Table 1.
Demographic and dietary characteristics of participants by potato consumption in the NIH-AARP diet and health study1.
Table 2.
Age and sex adjusted and fully adjusted hazard ratios for overall and cause specific mortality, for categories of total potato consumption (n = 410,701).
Fig 1.
Hazard ratios for overall mortality for different types of potato preparation.
Point estimates represent highest (≥7 times per week) vs. lowest category (<1 time per week) of consumption adjusted for age (years), sex (M, F), use or non-use of pipes or cigars, the number of cigarettes smoked per day, time of smoking cessation (<1 year, 1 to <5 years, 5 to <10 years, or ≥10 years before baseline), alcohol drinking (grams per day), ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic, Asian/Pacific Islander/Native American), body mass index (BMI)(kg/m2), education (high school or less, post-high school training, college graduate, post-graduate education), physical activity (never, rarely, 1–3 times per month, 1–2 times per week, 3–4 times per week, ≥ 5 times per week), self-report history of diabetes (yes, no), calories (kcal per day, quintile), red meat intake, white meat intake, whole grain intake, fruit intake, and vegetable intake (grams per day, quintile); HRs (95% CIs) were calculated by using a Cox regression model.
Fig 2.
Hazard ratios for overall mortality, for total potato consumption stratified by categories of suspected risk factors.
Point estimates represent highest vs. lowest category of potato consumption adjusted for age (years), sex (M, F),use or non-use of pipes or cigars, the number of cigarettes smoked per day, time of smoking cessation (<1 year, 1 to <5 years, 5 to <10 years, or ≥10 years before baseline), alcohol drinking (grams per day), ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic, Asian/Pacific Islander/Native American), body mass index (BMI)(kg/m2), education (high school or less, post-high school training, college graduate, post-graduate education), physical activity (never, rarely, 1–3 times per month, 1–2 times per week, 3–4 times per week, ≥ 5 times per week), self-report history of diabetes (yes, no), total energy intake (kcal per day, quintile), red meat intake, white meat intake, whole grain intake, fruit intake, and vegetable intake (grams per day, quintile); HRs (95% CIs) were calculated by using a Cox regression model.* P for interaction <0.05.
