  1. The fully adjusted model includes age (years), sex (men, women), educational attainment (no education, primary, secondary or higher), occupational status (employed, unemployed, retired, househusband/housewife), alcohol intake (g/d), former drinking (yes, no), extreme sleep duration (yes, no), body mass index (kg/m2), waist circumference (cm), systolic blood pressure (mm Hg), hypercholesterolemia status (yes, no), and history of coronary heart disease (yes, no), stroke (yes, no), diabetes mellitus (yes, no), hip fracture (yes, no), and cancer (yes, no).+ indicates the addition of each variable or variables to the full model. χ 2 is the likelihood ratio statistic for each variable or variables when added to the full model. P-values for pairwise comparisons between the presented model and the full model. Traditional behaviors: smoking, physical activity and diet. Non-traditional behaviors: sleeping, sitting time and social interaction with friends. a P <0.001 compared with the model with three traditional behaviors combined. b P = 0.040 compared with the model with three traditional behaviors combined.
