Odds ratios of sarcopenia according to childbirth parameters

Variable	No. of deliveries	Age at first delivery	Age at last delivery	Duration from last delivery
Unadjusted	0.93 (0.84–1.03)	1.01 (0.96–1.07)	0.998 (0.97–1.03)	1.04 (1.01–1.08)
Model 1	0.78 (0.67–0.90)	1.05 (0.99–1.12)	0.95 (0.91–0.99)	1.05 (1.01–1.10)
Model 2	0.78 (0.65–0.95)	1.02 (0.95–1.10)	0.95 (0.91–0.99)	1.06 (1.01–1.12)
Model 3	0.79 (0.64–0.97)	1.05 (0.95–1.10)	0.95 (0.91–1.002)	1.05 (0.99–1.11)

Values are presented as odds ratios (95% confidence intervals). Model 1: adjusted for age, alcohol, smoking, and physical activity; model 2: adjusted for variables considered in model 1+body mass index, level of education, and house income; and model 3: adjusted for variables considered in model 2+total energy intake per day, total protein intake per day, duration after menopause, and oral contraceptive use.
