Abbreviations: CI, confidence interval; SD, standard deviation.

* Generalized estimating equations was used to estimate the relative risk (and 95% CI).

^† Mixed-effects linear regression was used to estimate the difference in mean change between study groups.

^a One serving of fruit equals a medium-sized fruit or two small-sized fruits or half a glass of fruit juice or a bowl of grapes. One serving of vegetables (excludes tubers) equals 80 grams.

^b Self-reported history of moderate or vigorous physical activities during leisure time performed in bouts of at least 10 minutes’ duration.

^c Smoking or use of smokeless tobacco (chewing tobacco and snuff) in the past 30 days.

^d Consumed an alcoholic drink (spirits, wine, beer or toddy [palm wine]) in the past 30 days.

^e One standard drink of alcohol refers to 30 ml of spirits, 120 ml of wine, 285 ml of beer, or 285 ml of toddy (palm wine).
