Abstract

We examined the association between physical activity and reproductive factors with bone density among 313 Mexican women, aged 26–83 years. Bone mineral density (BMD) was measured with a HOLOGIC QRD 1000 w, DXA densitometer at the lumbar spine and femoral region. We explored the relation between BMD and parity, age, body mass index (BMI), type of menopause, and level of exercise. Multiple regression models examining determinants of bone density at the lumbar and femoral regions showed that increasing age and lack of exercise were statistically significant predictors of bone demineralization. The number of pregnancies also had a deletereous effect on bone density, especially for lumbar spine, as well as BMI < 20 kg/m2. Our results suggest that physical activity, parity, and BMI are important determinants of bone density in this population.
