a
Continuous and categorical measures of parity were added in separate models to examine linear and non-linear associations.
b
Controlling for age, weight, and dummy variables indicating whether lactating and pregnant at BMD measurement
c
Controlling for age and weight (no nulliparous post-menopausal women were sampled)
