Anthropometric and lifestyle associations of bone mass in healthy pre-menopausal Mexican and Asian American women.
Few studies have established the lifestyle predictors of peak bone mineral density (BMD) in Mexican-American (MA) and Asian-American (AA) women. Pre-menopausal MA (n = 48) and AA (n = 58) women aged 30-45 years old were tested for BMD, body composition, aerobic fitness, and muscle function. Socio-demographic characteristics, health status, prevalence of osteoporosis risk factors, physical activity, and diet were determined via questionnaire. Pearson's correlations and multiple linear regressions were used to test the associations between various osteoporosis risk factors and BMD. Body composition, anthropometric, and BMD differences were noted between groups. Hip, but not spine BMD, remained significantly higher for the MA compared to the AA group after adjustment for age, BMI, income, and physical activity index. Lean body mass was a significant predictor of hip BMD for both groups and this relationship was stronger for the AA group. Lean body mass may explain ethnic differences in BMD.
