  1. 1All values are odds ratios and 95% confidence intervals.2Obtained by the use of tertiles of DPI as an ordinal variable in the model.3Model 1: Adjusted for age, and energy intake in stratified analysis for sex categories. Adjusted for age, sex, and energy intake in stratified analysis for BMI categories.4Fully-adjusted model: Additionally adjusted for marital status, physical activity (HEPA), homeownership, anti-depressing medication, education status, obstructive sleep apnea (OSA), family size, history of diabetes, coffee and tea intake after 8 pm, and BMI in stratified analysis for sex categories. Additionally adjusted for marital status, physical activity (HEPA), homeownership, anti-depressing medication, education status, obstructive sleep apnea (OSA), family size, history of diabetes, coffee and tea intake after 8 pm in stratified analysis for BMI categories.
