Abbreviation: FSH, follicle-stimulating hormone.
a Weighted percentage accounting for the complex survey sampling design, not including missing data. Some data were missing (unweighted n’s) for education (n = 5), family income (n = 23), smoking (n = 7), body mass index (n = 1), age at menarche (n = 14), unilateral oophorectomy (n = 5), hysterectomy (n = 2), and postmenopausal status (n = 1).
b Total combined family income in the last 12 months.
c Participants were considered never drinkers if they had never consumed at least 12 alcoholic drinks; former drinkers were defined as those who had ever consumed at least 12 drinks but reported not consuming at least 12 drinks in the past 12 months; and participants were defined as current drinkers if they had consumed at least 12 drinks in the past 12 months.
d Participants were considered never smokers if they had never smoked at least 100 cigarettes in their lifetime; former smokers were defined as those who had ever smoked at least 100 cigarettes but reported having quit smoking.
e Weight (kg)/height (m)2.
