Dietary adherence and its determinants among type 2 diabetes population in Ethiopian: a systemic review with meta-analysis

PLOS ONE

Dear Dr. Abate,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Specifically the reviews were positive, and the study is thought to be impactful. There are a number of suggested edits to the manuscript that may make the manuscript easier to read. In addition, there are a few questions that the reviewer has raised that should be addressed, including why the participants aged 30 and above were considered an inclusion criteria, and how you assured the third independent review’ quality.

Please submit your revised manuscript by Mar 27 2022 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org.

2. Review Comments to the Author

REVIEWER #1 COMMENTS

1. COMMENT: Were the “independent reviewers” enough experienced to review? They should be

well-experienced reviewers, so it would be better to mention their level.

RESPONSE: they review each article independently. The have experience to review the quality of articles using assessment check list. The also published article systemic review and meta-analysis. They are assistant professors.

2. COMMENT: Change “Is” to “was”. Please proofread the manuscript again to revise minor

mistakes.

RESPONSE: Thank you this comment. We change the word ‘is’ to ‘was’ in the revised manuscript.

3. COMMENT: Remove one “with”. There are two “with”.

RESPONSE: we remove the word ‘with’ which was a typo error.

4. COMMENT: Why the participants aged 30 and above were considered an inclusion criteria? This is not consistent with the analyzed study target generation.

RESPONSE: We accept the constructive comment. We made editorial error in the inclusion criteria. We corrected as age 15 and above in the revised manuscript.

5. COMMENT: “find articles by reviewing the 5 reference lists of already identified researches.” This sentence is not easy to understand. Please rephrase.

RESPOSE: we try to rephrase these sentence

6. COMMENT: How did you assure the third independent review’ quality?

RESPOSE: through discussion using article review check list

7. COMMENT: How did you assure the “Discrepancies between reviewers resolved by discussion”? How was the discussion conducted?

RESPONSE: through discussion using article review standard check list

8. COMMENT: Please rephrase “the risk of bias of included studies”. It is difficult to follow.

RESPONSE: we try to clarify by rephrasing.

9. COMMENT: “For 2 the least risk of bias classification, discrepancies between the reviewers resolved via consensus” How did you assure the validity? Did you use any references? ….

RESPONSE: we use standard reference and quality assessment check list as we cited and provide supporting data. The last sentence was mistakenly written and we remove it.

10. COMMENT: “study setting (hospitals)” is this type of hospital? Please rephrase to make it clear.

RESPONSE: yes it is type of hospital (referral and general hospitals). We also include the manuscript.

11. COMMENT: Why was P-value set at 0.1, not 0.05? P-value of 0.05 has more significant than that of 0.1 statistically

RESPONSE: As far as our knowledge, we considered P-value less than 0.1 is more significant in Egger’s test of regression. If we set P-value at 0.05, we increase a chance to include a small study which turn increase bias. We are ready to learn if we understood in the wrong way, thank you.

12. COMMENT: “Eff ect” and “aff ected” It looks there are redundant space between f and e.

RESPONSE: we avoid space and rewrite again in the revised manuscript.

13. COMMENT: The response rate was quite high. Any bias? Did all studies take appropriate ethical consideration measure?

RESPONSE: During our review of the study articles, we thoroughly review the quality of study including the ethical review for each articles.

14. COMMENT: “study setting (hospital)” Same comment to page 8 line 14.

RESPONSE: we rewrite and make consistence

15. COMMENT: Miss typo “estimatio”

RESPONSE: Yes positively it is a miss typo, we corrected it.

16. COMMENT: Please rephrase “Egger’s test of the intercept 5 was 0.291 (95% CI: -0.085, 0.667) p > 0.05 (0.121) as judged by Egger’s test”. It is not easy to follow.

RESPONSE: we try to rephrase and try to clear for reader.

17. COMMENT: What is the evidence of “Dietary adherence emphasizes the importance of minimizing macro-vascular and micro- vascular complications in people with diabetes?”

RESPONSE: reference 62 is an evidence of the importance of minimizing macro-vascular and micro-vascular complication.

18. COMMENT: What is these “interventions”? There are various interventions for DM control

RESPONSE: intervention stands for ‘pharmacological intervention’

19. COMMENT: The knowledge of healthy diet behaviour would be different from the knowledge

gained at primary/junior high schools. Why we can say this relation?

RESPONSE: Being higher education levels could lead to having better judgment and decision-making ability for choosing healthy diet and eating behaviors

20. COMMENT: It should be that low-income participants are prone to follow unhealthy diet. It is not consistent with the findings. Why "emotional distress" is raised here suddenly? What is the meaning of "emotional distress" here?

RESPONSE: Yes it is not consistence. We re-edit as recommended.

21. COMMENT: “the cost of healthy diets increased with increasing 6 income quintiles” This is not clear. The expenditure of healthy diets?

RESPONSE: Accept the comment and re-edit in the revised manuscript.

12. COMMENT: What is the level of knowledge compared to a low level of it?

RESPONSE: Moderate and high level of knowledge

22. COMMENT: What is the difference of simple sugar and "sugar"? If there is no difference, it would be better to rephrase "sugar"

RESPONSE: we rephrase it.

23. COMMENT: Why "nutrition knowledge" is started to discuss here. The main theme should be summarized at the last paragraph. “nutritional knowledge” should not be fully equal to dietary adherence and healthy diet behavior for type 2 DM.

RESPONSE: We rephrase as dietary knowledge and rearrange the paragraph in the revised manuscript. This is not the main theme rather it is a discussion of the implication of dietary knowledge to dietary adherence.

24. COMMENT: What is the several strengths? I can identify only one strength of the sample size. Please mention clearly several strengths, if you want to say them here.

RESPONSE: we try to mention 1) large sample size, 2) pooled the proportion of dietary adherence and 3) pooled the proportion of common determinants of dietary adherence in the nation. As the review comment we rephrase the word several.

25. COMMONT: What is the result of the trial? Just "tried" cannot be the strength of this study.

RESPONSE: we try to rephrase this sentence in the revised manuscript.

26. COMMENT: Please rephrase “all primary studies were cross-sectional that is limited in this

study”. It is not easy to follow.

RESPONSE: since we are not incorporated a primary study those with a method of case-report study, qualitative study, and longitudinal study design.

Future research should focus on developing and testing a conceptual model that can use to enhance diabetes self-care practice in a national context. Finally, to give a long-term reduction in diabetes-related co-morbidity and mortality, researches should assess ways to extend and sustain diabetes self-care practice among this population.

27. COMMENT: What is the results of your trial? As the result, what is the limitation? Please rephrase to make clear the limitation. “Besides, we 8 tried extensive and diverse search strategies to find all possible available literature, some grey 9 literature, such as conference proceedings, remained difficult to find.”

RESPONSE: We try to rephrase these comment.

28. COMMENT: What kind of “effective strategies” could be suggested from this study? Please

describe.

RESPONSE: We try to describe in bracket in the revised manuscript.

29. COMMENT: “Future research should focus on development” What for is “development”?

RESPONSE: This is an editorial error. We complete the sentence and make clear the reader.

30. COMMENT: “Testing recommends food availability, affordability, and cultural acceptability in the 18 context of Ethiopians.” Please rephrase. What is “testing”?

RESPONSE: rephrase the word testing in the revised manuscript

31. COMMENT: What is the evidence of “based on what they see, hear, feel, and perceive the

healthy diet”?

RESPONSE: Since it make unclear for reader, we rephrase as ‘and attitude towards healthy diet during dietary counseling and education’

32. COMMENT: Please rephrase “Ensure more focusing on eating a healthy diet is as preventive and curative measures for 3 diabetes in health education programs as well in medical

curricula.” to make the meaning clear.

RESPONSE: Rephrase the sentence to make clear reader

COMMENT: The style of Reference does not follow the guideline. Please recheck the style.

RESPONSE: We try to follow the guideline.
