With an ageing population, there is an increasing societal impact of ill health in later life. People who adopt healthy behaviours are more likely to age successfully. To engage people in health promotion initiatives in mid-life, a good understanding is needed of why people do not undertake healthy behaviours or engage in unhealthy ones.
Searches were conducted to identify systematic reviews and qualitative or longitudinal cohort studies that reported mid-life barriers and facilitators to healthy behaviours. Mid-life ranged from 40 to 64 years, but younger adults in disadvantaged or minority groups were also eligible to reflect potential earlier disease onset. Two reviewers independently conducted reference screening and study inclusion. Included studies were assessed for quality. Barriers and facilitators were identified and synthesised into broader themes to allow comparisons across behavioural risks.
From 16,426 titles reviewed, 28 qualitative studies, 11 longitudinal cohort studies and 46 systematic reviews were included. Evidence was found relating to uptake and maintenance of physical activity, diet and eating behaviours, smoking, alcohol, eye care, and other health promoting behaviours and grouped into six themes: health and quality of life, sociocultural factors, the physical environment, access, psychological factors, evidence relating to health inequalities. Most of the available evidence was from developed countries. Barriers that recur across different health behaviours include lack of time (due to family, household and occupational responsibilities), access issues (to transport, facilities and resources), financial costs, entrenched attitudes and behaviours, restrictions in the physical environment, low socioeconomic status, lack of knowledge. Facilitators include a focus on enjoyment, health benefits including healthy ageing, social support, clear messages, and integration of behaviours into lifestyle. Specific issues relating to population and culture were identified relating to health inequalities.

With an ageing population, there is an increasing economic, societal and health and social care impact of dementia, disability, frailty and non-communicable chronic diseases (NCDs) in later life. Ill health in later life is heavily influenced by behaviours across the life course, which in turn are influenced by a variety of wider contextual social, economic, and organisational factors [1,2]. People who adopt healthy behaviours are more likely to age successfully and have improved quality of life [3–5].
As they age, those people now in mid-life have a greater risk of development of disease and frailty than younger people in the next decades [6–8]. There is also considerable potential for inequalities in health promoting behaviours and health outcomes, arising from poverty, social and environmental factors [9,10], so risk factors for ill health in later life may manifest at a younger age in disadvantaged, minority or harder to reach groups. To minimise the risk of ill health in later life in these populations, effective ways to change people’s behaviours are needed. In order to engage people in health promotion initiatives in mid-life and inform the design of effective interventions that consider their specific circumstances, a good understanding is needed of why people do not undertake healthy behaviours or engage in unhealthy ones.
This systematic review was one of a series of reviews conducted to inform the development of UK national public health guidance on mid-life approaches to prevent dementia, disability and frailty (DDF) in later life (https://www.nice.org.uk/guidance/ng16). The aim of the review was 1) to identify key issues (barriers and facilitators) for people in mid-life that prevent or limit or which help or motivate them to take up and maintain healthy behaviours that may ultimately impact on healthy ageing including prevention or delay of dementia, disability, frailty or NCDs, and 2) to identify any specific issues that may influence health inequalities, for example by ethnicity, socioeconomic status, gender or in minority or harder to reach groups. Clearly, the goal was not to summarise the whole of the public health literature on barriers and facilitators to behaviour change. Rather, we aimed to identify evidence targeted at or of particular relevance to people at mid-life. People in this segment of the population are likely to share some of the same issues and challenges when it comes to changing or maintaining behaviours. With a similar focus, the other two reviews in the series looked at the association between mid-life risk factors and late life outcomes, and at the effectiveness of mid-life interventions on behavioural risks and late life outcomes.
The review was conducted as a rapid systematic review to provide best available evidence within limited timescales. The scope of the review was defined by the funders (National Institute for Health and Care Excellence—NICE), after open consultation with stakeholders and the protocol (available on request) was agreed prior to the start of work. Established systematic review methods of NICE  were broadly followed, except as described below.
Searches: The following electronic sources were searched for peer-reviewed studies published in the English language (to March 2014): MEDLINE; EMBASE; PsycINFO; CINAHL; HMIC; Cochrane Central Register of Controlled Trials; Cochrane Database of Systematic reviews; Database of Abstracts of Reviews of Effectiveness; HTA database; NHS EED database; Web of Science, Applied Social Sciences Index and Abstracts and relevant websites (S1 Text). Time constraints precluded hand searches or contact of authors for additional data.
Searching was conducted 1) for systematic reviews using a search filter (SIGN filter ) for a broad range of health behaviours, 2) for primary studies for a broad range of health behaviours specifically at mid-life, and 3) specific targeted searches for studies where there were gaps in the evidence, relating to vision, hearing and inequalities. Due to an initial large number of search hits, searches were limited by the use of mid-life terms and indexing (S2 Text). Studies from any country, published in English, from year 2000 onwards were eligible.
Inclusion and exclusion criteria
Populations: The populations covered by this review included 1) mid-life adults (aged 40–64 years), including those at increased risk of disability, dementia, frailty, or other NCDs or 2) adults aged 39 and younger in populations at higher risk of health inequalities, which refer to people from disadvantaged and minority groups. These groups include (but are not limited to) people of low socioeconomic status, ethnic minority groups, lesbian, gay, bisexual and transgender (LGBT) groups; travellers, and other groups with protected characteristics under the equality and diversity legislation.
Outcomes: Barriers and facilitators which prevent or limit or which help and motivate people to take up and maintain healthy behaviour, including (but not limited to): 1) physical activity or inactivity; diet and nutrition; weight loss (in overweight people) or control; smoking or tobacco consumption; alcohol consumption; multiple behavioural risk factors; healthy behaviours in general, social activity or prevention of loneliness; prevention of sight or hearing loss 2) behaviour at individual, group, family, community level in any setting. Barriers and facilitators relating to participation in or effectiveness of specific interventions are not included.
Study design: Systematic reviews, primary qualitative studies and primary longitudinal cohort studies were considered for inclusion in this review. As few reviews focused on mid-life, systematic reviews in adults in general were included.
Exclusions: Studies in populations with: existing dementia or cognitive impairment, disability, frailty and NCDs, including obesity or their diagnosis, care and management. Barriers and facilitators to: use of medications; recreational drugs; supplements; national policies, legislation or implementation. Cross-sectional studies, systematic reviews that only included cross-sectional studies, abstracts, letters, editorials and unpublished theses were excluded.
Identification of relevant studies: Titles and abstracts were screened, and then checked, independently by two reviewers. Differences were resolved by discussion or with a third reviewer. Fig 1 illustrates the flow chart for the study selection process. Studies excluded at the full paper screening stage are reported in S1 Table along with reason for exclusion.
Assessment of methodological quality: Systematic reviews were assessed using AMSTAR . Primary studies were assessed using NICE checklists [14,15] and rated as ++, + or–based on the checklist criteria (Table 1; detailed assessments are in S2 Table). A minimum of 10% of the studies were assessed by two reviewers and discrepancies resolved by discussion. No studies were excluded on the basis of methodological quality.
Data extraction and evidence synthesis: Study data was extracted on population, setting, study design, outcomes, method of analysis, results and funding (S3 Table) by one reviewer and checked for accuracy by another. Issues relevant to the uptake and maintenance of health behaviours and their context were identified in the literature and analysed thematically to identify common themes, integrating qualitative and quantitative evidence .
In total 81 studies (46 systematic reviews and 39 primary studies specifically in mid-life) are included in the review. The studies’ characteristics and overall quality ratings are shown in Table 1 (Detailed quality assessments are in S2 Table).
Nineteen systematic reviews focused on physical activity, seven on diet, three on overweight, four on smoking, three on alcohol consumption, four on cardiovascular health, and six on health promoting practices more generally. Most reviews focused on the adult population in general with six examining specifically mid-life populations. Of the 46 reviews, seven focused on ethnic groups, nine related to disadvantaged groups, four focused specifically on women.
All 39 primary studies focused on specifically mid-life healthy behaviours. Of these, 28 were qualitative studies and 11 were longitudinal cohort studies. In the qualitative studies, 15 were in women only and five in men only, four studies were relevant to health inequalities focused on ethnic groups or deprived, hard to reach or minority groups. Of the cohort studies, four studies were exclusively in female cohorts and two in male cohorts.
The findings were organised in three levels (Table 2): 1) by health behaviour: evidence was found for physical activity, diet, smoking, smokeless tobacco, alcohol, eye care, health behaviours in general including cardiovascular prevention 2) under broad themes identified: health and quality of life, sociocultural factors, the physical environment, access to facilities and resources, psychological factors, health inequalities 3) barriers and facilitators identified within each broad theme. Some issues could be both barriers and facilitators depending on the context.
Physical Activity (PA)
Health and wellbeing.
Barrier: Existing physical ailments or chronic conditions were a barrier to PA participation in four qualitative studies [17–20], one cohort , and three systematic reviews [22–24].
Facilitators: 1) Improved sense of wellbeing, energy, positive feelings or self-esteem. Evidence from six qualitative studies [18–20,25–27] indicates that promotion of ‘feel good’ benefits like greater self-esteem and confidence can be a motivator for behaviour change. A cohort study  found that females who focused on a sense of wellbeing and/or stress reduction goals participated in significantly more PA than those who focused on weight loss and/or health benefits.
2) Health benefits in general. Eight qualitative studies [17,18,20,25,27,29,30,31] and a cohort study  reported improved health benefits as motivators for participation in PA. Another cohort study  found that a high value placed on health was positively associated with change in health practices in men. One systematic review  found associations between expected health benefits and PA in repeated studies.
3) Fear of illness or ageing and wanting to promote a healthy old age was reported in seven qualitative studies [17,18,20,25,29,31,34] so that people were able to do the things they wanted, for example, travel, hobbies and caring for families in later life.
4) Weight loss, body image, physical appearance was reported in six qualitative studies [17–19,25,27,35]. However, in cohort studies [28,35], participants with weight loss goals participated in significantly less PA than those with sense of wellbeing or stress reduction goals or body shape, toning or losing weight motives.
5) Enjoyment of the activity. There is consistent evidence from three qualitative studies [18,20,30], one systematic review  and one cohort study [33,36] in which ‘enjoyment’ was a powerful determinant of later PA.
6) Previous experience of ill health. Two qualitative studies [19,29] reported ill health (high blood pressure, diabetes, obesity, stroke) as a motivator for PA and one reported a family history of disease was important when considering preventive health care . However, evidence was not always consistent. In cohort studies, elevated blood pressure, risk factors for cardiovascular disease or myocardial infarction were associated with positive lifestyle changes in men  but a history of hypertension or diabetes was not .
7) Integration of PA into lifestyle. In qualitative studies  key messages related to positive swapping of behaviours; for example, walking as an easily integrated part of everyday activity to replace sedentary travel  and strategies for incorporating PA into daily lifestyle ; a systematic review in UK South Asian populations found a need for PA to be incorporated into everyday activities .
8) Focus on short-term benefits. One qualitative study found the promotion of short-term benefits that are quickly achievable, potentially leads to longer-term benefits such as prevention of heart disease .
9) Supplying the tools to make and sustain behaviour changes. In one qualitative study most people felt they lacked specific information and strategies to make changes in their daily lives .
Barriers: 1) Lack of time. In seven qualitative primary studies, lack of time was raised as a barrier to participation in mid-life activity [17–20,25,29,41] in particular because of conflicting demands of work, childcare, family and household responsibilities in all genders and ethnic groups represented. Additionally, six systematic reviews also raised relevant barriers relating to lack of time [23,24,33,42]; high job strain  and having child care responsibilities .
2) Self-consciousness or social concerns. Concerns about social discomfort or self-consciousness about participation in PA programmes or in the gym were raised in three qualitative studies [19,39,44], all in women.
3) Lack of knowledge. This was raised in one qualitative study  in middle-aged women in Iran and one systematic review in adults in general .
Facilitators: 1) Support. Supportive partners, family or friends, having a companion to do PA, or support from a physician were cited as facilitators of PA in three qualitative studies [17,20,30] and three systematic reviews [22,33,42]. Conversely, lack of support was cited as a barrier in four qualitative studies [17,20,29,41].
2) Being a good role model. Two qualitative studies in men [25,34] reported being a good role model for children and others as being a motivator for PA.
Barrier/Facilitator: Life changes/more time at home. In one qualitative study, middle-aged adults reported spending more time in front of the computer or TV once children had moved out . A review  found that changes at work were associated with increased PA in middle-aged women.
Barriers: 1) Neighbourhood safety. Two qualitative studies [19,29] and three systematic reviews [22–24] reported concerns about unsafe neighbourhoods.
2) Weather. Two qualitative studies in women reported the weather as a barrier to PA participation [19,39].
3) Driving instead of walking. One qualitative study reported tendency to drive instead of walk, with cars seen as a symbol of status and security .
4) Lack of recreational space. One systematic review in mid-life populations reported lack of parks or recreational space and traffic as a barrier .
Access (to facilities and resources).
Barriers: 1) Financial costs. Three qualitative studies [18,20,34] and one systematic review  reported that the costs of organised PA or fitness club membership were a barrier to PA.
2) Transport issues. Inconvenience, for example, having to drive to participate in PA, was cited as a barrier in one qualitative study in men . Lack of transport was a barrier to PA in one qualitative study in women  and in one systematic review in adults .
3) Lack of availability or access to community programmes and facilities. Two qualitative primary studies [17,19] and two systematic reviews highlighted lack of availability or limited places on PA programmes or access to places to do PA including recreational space, gyms [22,24].
4) Programmes delivered by mobile phones/social networking. One qualitative study  found interventions delivered via mobile phone was not of interest to most participants; though if they had a smartphone they were more open to the idea. Social media networking was not a high priority in the mid-life population studied due to lack of time.
Facilitator: Fast, easy to use websites. Middle-aged men preferred websites that were fast, easy to use, clutter-free, and concise with reliable information and interactive features that could give feedback, such as podcasts, step-by-step videos and pictures .
Barriers: 1) Lack of motivation. This was reported in three qualitative studies [19,25,34] and one systematic review .
2) Low self-efficacy. Three systematic reviews in adults found a relationship between self-efficacy (belief in one’s own ability to complete tasks and reach goals) and PA participation [33,47,48]. Two qualitative studies [20,41] in women found perception of lack of capability often prevented PA participation.
3) Entrenched attitudes and behaviours in mid-life. For example when structured PA was not a part of self-identity or had become associated with a fear of being judged for decreasing abilities .
Facilitator: Positive view of ageing. One cohort study  found that a positive view of ageing was associated with increased sporting activity in those who were healthy enough to take part.
Barriers or facilitators cited previously were also applicable in broader population groups. Only those more specific to disadvantaged and minority groups are discussed here:
Barriers: Six systematic reviews [22,33,50,51–53] in adults in general linked higher SES, education or income with higher levels of PA. Lower occupation status was associated with higher total PA in one review  and two reviews [52,53] reported a higher level of occupational PA in lower socioeconomic groups; those with higher socioeconomic position were more active during leisure time.
Ethnic minority groups.
Barriers: 1) Language barriers. Language was highlighted as a barrier to PA participation in two qualitative studies in US women [19,41], one in an Asian population and one in a Latin-American population.
2) Cultural barriers. Cultural beliefs and traditional roles for women that focus on family and domestic duties were cited in US qualitative studies, in Asian [29,41] and Latin American populations . An emphasis of intellectual activity over physical activity in Asian culture was also a barrier . From systematic reviews [23,40], culturally inappropriate facilities included mixed sex swimming pools and male instructors (for women).
Facilitators: 1) Type of activity. Walking was most commonly recommended PA followed by sports-related activities in one qualitative primary study in mid-life African American men [23,34].
2) Having exercise equipment at home. South Asian populations reported this as a facilitator .
Gender and gender roles.
Barriers: 1) Female gender and gender roles. This was highlighted in four qualitative studies [19,29,30,41] and three systematic reviews [23,40,54], including two specifically in South Asian women. One systematic review  reported that women were more likely to begin exercise referral schemes but less likely to maintain participation.
2) Hair maintenance. One systematic review found that hair maintenance was perceived as a barrier to PA in African American women .
Facilitator: Physically active female role models. One systematic review in adult women in general found  that they would feel more confident about adding PA to their lifestyles if they had female role models.
Health and quality of life.
Barrier: Misinterpretation of health messages. In a UK qualitative study , misinterpretation of food messages like eating ‘five a day’ could mean fruit and vegetables were being added to existing daily food intake.
Facilitators: 1) Clear and simple food advice. One qualitative study about bone health  found that women preferred to have clear and simple food choices for overall health.
2) Health concerns. In one qualitative study in US women  food choices were affected by personal health concerns.
3) Previous experience of ill health. In one qualitative study , a motivating factor for changes in diet relating to bone health was diagnosis of osteoporosis in a family member.
4) Focus on swapping foods. A UK qualitative study  reported that strategies for replacing unhealthy snacks with healthy ones, replacing high calorie meal components with lower calorie ones providing new and interesting ways to add fibre to the diet were behaviour change messages that engaged mid-life adults. Reducing alcohol consumption was less motivating due to the pleasure associated with drinking.
5) Weight loss/short term benefits. Promotion of weight loss was a facilitator for dietary change when it was supported by information on other short-term benefits .
6) Supplying the tools to make and sustain behaviour changes. Most people felt they were aware of the changes they needed to make but lacked the specific information and strategies to make the changes in their daily lives .
Barriers: 1) Eating out of home. In one systematic review , eating out of home was associated with higher energy and fat intake and lower micronutrient intake.
2) Competing priorities. One systematic review  identified competing food choice priorities as a barrier. These included enjoyment, cost, managing relationships and convenience and may be influenced by personal, social and food context.
3) Lack of time. Insufficient time for healthy eating was highlighted in one systematic review  often related to family schedules and work demands.
4) Unplanned shopping routines. In a qualitative study  it was found that unplanned shopping trips encouraged impulsive and indulgent purchases.
5) Co-existence of other unhealthy lifestyle behaviours. In a qualitative study, , alcohol consumption increased the energy of the overall diet and encouraged unhealthy food choices. In one cohort study, drinkers or smokers were more likely to consume higher amounts of fatty, sweetened or salted foods .
Facilitator: Support. Family support was a determinant of the uptake and maintenance of healthy eating behaviour in one cohort study  and identified as a factor influencing eating behaviour in one systematic review .
Barrier/facilitator: Social environment around food. In one qualitative study conducted in women  food choices were influenced by family members and co-workers. In one systematic review , social relationships and context influenced how people interpret healthy eating.
Barrier/facilitator: Food environment. In one qualitative study conducted in US women , food chosen at home and at work was influenced by the surrounding food environment including the type of food available and convenience of access. In two systematic reviews [62,63], greater access to supermarkets or less access to takeaway outlets was associated with lower prevalence of overweight and obesity but mixed associations were found with dietary behaviours .
Access (to facilities and resources).
Barriers: 1) Financial costs. One systematic review  found that people reported that healthy foods were too expensive.
2) Interventions delivered by mobile phones/social networking were considered in one primary qualitative study, as above .
Barrier/Facilitator: Food accessibility or availability. Widespread availability of unhealthy food such as junk food and lower availability of healthy food was reported in a systematic review . Another review  found some limited evidence that fruit and vegetable consumption was higher when more easily available and having your own vegetable garden or a supermarket in the local area.
Facilitator: Fast, easy to use websites. One primary qualitative study , as above.
Barriers: 1) Perception of lack of capability/knowledge/motivation. In one systematic review beliefs about capabilities and knowledge and motivation were consistently associated with fruit and vegetable intake .
2) Existing entrenched behaviours around eating. In one qualitative study  unhealthy behaviours around eating were deeply embedded, such as snacking, bingeing, junk food, skipping meals, oversized portions, or fussy eating habits retained from childhood.
Barrier/facilitator: Identity. One systematic review  reported the influence of a person’s self-concept on how they eat, as some people desire to be healthy eaters whereas others viewed it as weird or picky.
Barriers: 1) Socioeconomic status. Lower household income or SES was associated with lower fruit, vegetable or fibre consumption and higher total fat intake from three systematic reviews [62,64,66]. A further review found that fast food restaurants were more prevalent in low-income areas .
2) Food environment. In two systematic reviews [63,68] there was some limited data that the food environment (greater access to supermarket or less access to takeaway outlets) was associated with lower prevalence of overweight and obesity in socioeconomically deprived areas and in US black or Hispanic populations.
Health and quality of life.
Facilitators: 1) Participation in other healthy behaviours. One systematic review  and one cohort study  found that those who participated in other healthy behaviours were more likely to quit.
2) Initiation of prescribed drug use or development of disease were identified as facilitators in one cohort study .
Barriers: 1) Higher level of current smoking. In one cohort study  quit attempts were less successful in heavier smokers. In one systematic review, higher number of cigarettes smoked was associated with failed quit attempts .
2) Younger age of initiation of smoking. One cohort study found that those who started smoking at a younger age were less likely to stop smoking .
Facilitator: Motivational factors. In one systematic review , motivation to quit and intention to quit were positively associated with making a quit attempt but not with quit attempt success.
No studies identified barriers or facilitators related to the physical environment or access.
Barriers: 1) Low SES. One systematic review found that media campaigns to promote smoking cessation are often less effective in low SES groups . In another review , higher social grade was predictive of quit attempt success in two studies. One Japanese cohort study  found that white-collar workers were more likely to quit than blue-collar workers.
2) Unemployed young adults. One review reported a lack of literature relating to smoking cessation among unemployed young adults .
All data for smokeless tobacco is from one systematic review that examined the cultural and social acceptance of use in South Asian communities including in the UK, India, Pakistan and Nepal  and is summarised in Table 1.
Barrier: Neighbourhood disorder and crime. One systematic review  found evidence that alcohol use may be higher in communities with greater social disorders.
Barriers: 1) Availability. One systematic review  assessed the relationship between alcohol use and availability from commercial sources at the community level. Results were not significant in the included studies in adults overall but higher outlet density, defined as shops, bars and restaurants in a community, may be associated with an increase in alcohol use.
2) Advertising and media. One systematic review  assessed the relationship between alcohol use and advertising at the community level. Only one of the included studies for this exposure was conducted in adults (in women) but that study reported a significant relationship between advertising and alcohol use.
No studies were identified which assessed health and quality of life, access (to facilities and resources), or psychological barriers and facilitators.
Barriers: 1) Socioeconomic status. One UK cohort study  found that socioeconomic disadvantage was linked to mid-life moderate-binge, non-/occasional and problem drinking but not low-problem heavy drinking. One systematic review  found the association between community-level socio-economic factors (deprivation, income, employment) and alcohol use was inconclusive with some indication that alcohol use may be greater in high-income communities but also in communities with higher unemployment levels.
2) Gender. One review  concluded that while women with alcohol use disorders are more likely to seek help, they are less likely to be identified by their physicians. Barriers to seeking help include: fear of abandonment by partner, fear of loss of children and financial dependency.
3) Identity. One qualitative study  with lesbian women found that the use of alcohol can be associated with a disconnection from an individual’s identity; in particular with their lesbian identity but also from other roles such as student, partner, employee and parent or from childhood issues.
Eye Care Behaviours
Only one qualitative primary study was found for eye care in mid-life men and women in the US with little or no health insurance and is summarised in Table 2 .
Health Behaviours in General
Health and quality of life.
Facilitators: 1) Health check-ups. One cohort study  reported that those attending health check-ups were more likely to be engaged with healthy behaviours. In a qualitative study  most participants reported going for regular, quick annual check-ups; however women often reported that dismissive statements from healthcare professionals sometimes stopped them seeking preventive check-ups.
2) Knowledge of healthy behaviour. One qualitative study  found that health related knowledge, was positively related to health-promoting behaviours.
3) Participation in other healthy behaviours. One cohort study  found that participating in physical activity had a positive effect on mental health (which is positively associated with health-related behaviours) and in another cohort study  activity was a factor for success in lifestyle change. In a systematic review  lack of exercise experience was a barrier to adopting health-promoting behaviours. In one cohort study  lower alcohol intake was associated with positive lifestyle changes.
4) Experience or fear of ill health. One qualitative study conducted with women in Iran  found that development of, or fear of chronic disease, or disease in relatives, prompted more health-promoting behaviours.
Barrier: Lack of time. In a review  lack of time was reported to be a barrier to health-promoting behaviours. In one qualitative study  lack of time was reported to be a barrier to accessing the healthcare system for rural women.
Facilitators: 1) Being married or cohabiting. Non-attenders for health checks were more likely to be single in one systematic review . Another review  found that not being married, not living with a partner or being single could be a barrier to lifestyle change in (in six included studies while eight studies found no association). In one cohort study  being married or cohabiting at mid-life was a predictor of a positive change in health behaviour. However, in another cohort study  marital status was not significantly associated with successful lifestyle change.
2) Education. In one review , those not engaging with preventative health practices were less well educated. In two other reviews, people with higher levels of education tended to be more physically active  and engaged in self-care activities . In cohort studies, two cohort studies reported that education was one of the strongest predictors of a positive change in health behaviours  . However, education was not associated with positive lifestyle change in another cohort study .
3) Support. In one qualitative study  women found it difficult to sustain healthy practices if they had no one supportive of their efforts. One systematic review  found that physicians felt that their capability in helping patients change their lifestyle was generally low in the areas of smoking, nutrition, exercise, and alcohol consumption.
4) Benefits of health behaviour including the opportunity for socialisation and improved self-esteem was reported as a facilitator for women in one systematic review .
Barrier/facilitator: Family responsibilities. One cohort study  reported that having a child at home was one of the strongest predictors of a beneficial change in health behaviours. In a review  caretaking responsibilities and family obligations were found to be barriers to health-promoting behaviour.
Barrier: Distance. One review  found that longer travel time and greater distances from healthcare facilities, or problems with transport, were consistently associated with poorer uptake of lifestyle programmes. In rural mid-life women geographical barriers to accessing healthcare systems were reported .
Access (to facilities and resources).
Barrier: Lack of time (doctors). One review  found that some clinicians lacked time to spend on preventive medicine. In one US qualitative study  women reported that their physicians were very busy which prevented access to healthcare.
Facilitators: 1) Self-efficacy. Two reviews found that uptake of lifestyle programmes or lack of engagement with preventive health practices was related to self-efficacy [82,83].
2) Value placed on health. One cohort study  found that a high value placed on health was independently associated with positive change of general health practice. In one review  those not engaging with preventive health practices were shown to value health less strongly. In one qualitative study  women who valued their health were more likely to undertake health-promoting behaviours.
Barriers: 1) Lack of time. Two reviews [81,82] found that lack of time was a barrier to health-promoting behaviour. It was also raised as an issue in two qualitative studies in mid-life women who found family obligations and caretaking responsibilities limited time for healthy behaviours [31,37].
2) Entrenched attitudes and behaviours in mid-life. One qualitative study  reported resistance to the idea of change in mid-life, including reluctance to be told what to do and a belief that benefits of behaviour change needed to be experienced before adoption of the changes long-term.
Barrier: 1) Low SES. One review found that men on low incomes, low SES, and unemployed or less well educated were less likely than others to attend health check-ups . Lack of money was reported in one systematic review .
2) Gender. One review  and one cohort study  found that men were less likely to attend health checks or adopt a healthy lifestyle. In one qualitative study  in US women, various roles (caring for homes, jobs, children, grandchildren, and parents) women fulfilled limited time and access to the healthcare system. One qualitative study  found that social responsibilities inside and outside home interfered with participation in health behaviours. One systematic review  found that caretaking responsibilities and family obligations for women were a barrier to health behaviours relating to CHD.
3) Ethnicity. In a cohort study  conducted in the US, those from African American, or BME communities were less likely to adopt a healthy lifestyle.
This review found a broad range of barriers and facilitators that either prevent or limit, or which help or motivate individuals to take up and maintain healthy behaviours in mid-life. Evidence was found relating to barriers and facilitators to physical activity, diet and eating, smoking, smokeless tobacco, alcohol, eye care and health behaviours in general, in particular in relation to prevention of cardiovascular disease. Evidence was sought, but not found, for barriers and facilitators to other health behaviours, including mid-life social activity and prevention of hearing loss.
Most of the available evidence is from developed countries (European nations, USA, Canada, Australia and New Zealand). In relation to health inequalities, substantial evidence was found that low SES is a barrier to healthy behaviour. Evidence for both men and women at mid-life was found and the perspectives of a range of ethnic minority groups across different health behaviours were represented. There is a comprehensive study of barriers and facilitators to PA for disabled people in the US , and a qualitative study relating to alcohol use in lesbian women. However, there is little evidence relevant to other minority or disadvantaged groups or for different health behaviours.
The review had a wide scope as it sought information relating to a wide range of health behaviours in mid-life. In order to provide timely evidence and obtain a manageable number of search hits, the searches were limited to studies that included terms related to mid-life in the title, abstract or indexing terms. There may be other studies that include a predominantly mid-life population that have not been indexed in this way. While this was a rapid review, established, rigorous systematic review methods have been used and reported in the methods, inclusions, quality assessment and synthesis of studies [87,88].
Remarkably, we found no overlap between studies in systematic reviews and primary studies identified perhaps reflecting differing inclusion criteria and dates for systematic reviews and the challenges of searching the large volume of work that has been published in this area. This review has only included studies published from 2000 onwards so it may be that some of the available data was published before then.
Some systematic and narrative reviews included in this review contained both qualitative and quantitative studies, including cross-sectional studies. To compensate for this we extracted and focused on longitudinal data as much as possible, without going back to individual primary studies. Most of the data in included quantitative studies was self-reported (S3 Table), and few studies used objective measures.
Many of the barriers and facilitators identified were found in a number of different studies, across different study designs, ethnic groups, in men and women. Some of the same issues were also identified in disadvantaged and minority groups. Therefore there is a fairly high degree of confidence in the crosscutting barriers and facilitators identified. Additionally, some of the same barriers and facilitators were found across studies that examined different health behaviours.
Key barriers that recur across different health behaviours include lack of time (in particular in relation to family, childcare, household and occupational responsibilities), access issues (transport, facilities and resources), financial costs, personal attitudes and behaviours (including lack of motivation), personal identity, restrictions in the physical environment, low socioeconomic status and lack of knowledge. Key facilitators include a focus on enjoyment of the healthy behaviour, doing other healthy behaviours, health benefits, prevention of illness, the potential benefits for healthy ageing and wellbeing as motivation; social support and encouragement; clear, accurate health messages, and integration of behaviours into lifestyle and routine. Specific issues relating to population and culture were identified for disadvantaged and minority groups.
While a number of studies have shown that mid-life interventions can be effective in changing health behaviours for those that participate , few existing mid-life interventions have addressed issues that may affect uptake and participation in programmes or individual participation in the first place. There is scope to design tailored interventions at both population and individual levels that address the mid-life barriers and facilitators identified in terms of intervention design to address capability, opportunity and motivation , including ease of access to and take up of programmes.
Conclusion and Recommendations
The barriers and facilitators to mid-life health behaviours identified in this review are important considerations that can inform the design of mid-life interventions. While change in health behaviour can occur in mid-life, health behaviours may be more entrenched. Yet, there are opportunities to change behaviour as people start to think more about the need to maintain health in later life in order to make the most of retirement, family and grandchildren for example.
While interventions to change health-related behaviour in mid-life can be effective for people that participate in them, issues around access, including availability and affordability also need to be considered as part of the design of health promoting strategies to address time constraints and competing priorities, ease of access and financial issues for people in mid-life.
Strategies to promote mid-life healthy behaviours that could be considered include: The provision of locally available, affordable programmes that allow quick and easy access such as shorter, bite-sized interventions; strategies to enable people to integrate healthy behaviours into their daily lives, such as promotion of home-based interventions, for example quick home preparation of healthy food, home physical activity programmes or improving the local environment to encourage walking, cycling, active transport or healthier food outlets; promote programmes as an opportunity for socialisation, support and enjoyment; highlight the short-term and long-term benefits of healthy behaviour such as promotion of wellbeing and healthy ageing; ensure websites with information or programmes are fast and easy to use; develop interventions and strategies around children and family, using local community resources, including those that their children also use, such as schools and recreational facilities; provide interventions at convenient times and in easily accessible places, for example outside office hours, in workplaces or local community settings; provide programmes and information in a range of appropriate languages and culturally acceptable styles and facilities; target health promotion at times in people’s lives when substantial change occurs such as retirement or when children leave home; target lower socioeconomic status groups and consideration of specific strategies to encourage women to take up activity programmes.
Addressing barriers and facilitators of behaviour change in the design and implementation of public health interventions in mid-life, can inform the delivery of tailored, evidence-based strategies towards maintaining health in later life.
