aORs and CIs were adjusted for age, BMI and physical activity (as continuous variables for the three variables), smoking status (never, ex- and smokers = 0, 1 and 2), habitual drinking (never, ex- and drinkers = 0, 1 and 2), feeling stressed (many times, normal and rare = − 1, 0 and 1) and education level (< 12, 12 and ≥ 12 = 0, 1 and 2)
bTrend association was assessed by assigning ordinal numbers (− 1, 0 and 1) to unmarried, married and ‘bereavement/divorce’ for marital status, those (0, 1, 2 and 3) to single, couple, two generations and three generations for family structure, and then those (0, 1 and 2) to good, somewhat good and “not so good/not good” for family relationships, respectively
