	Total/cases	Model 1	Model 2	Model 3	Model 4
Age at menopause
≤44 years	1,733/125	0.96 (0.79–1.17)	1.00 (0.81–1.23)	1.03 (0.83–1.27)	1.06 (0.86–1.31)
45–52 years	12,991/948	Ref.	Ref.	Ref.	Ref.
≥53 years	2,352/215	1.25 (1.07–1.46)†	1.25 (1.06–1.47)†	1.21 (1.03–1.43)†	1.17 (0.99–1.39)

Model 1 only adjusted for age; model 2 adjusted for model 1 plus socioeconomic status and health behaviors including marriage status, education level, occupation, household income, parity, family history of diabetes, smoking status, alcohol consumption, sedentary/physical activity and use of contraceptive; model 3 adjusted for model 2 plus the physical measurements of body mass index and waist circumference; model 4 adjusted for model 3 plus hypertension. ^†Significant results.
