Abstract
Objectives: To investigate the relationship between lifestyle and hipbone mineral density (HBMD) in women. Methods: A cross-sectional study was conducted among 313 pre-menopausal and 96 peri/post-menopausal women who participated in health checkups between September 2000 and April 2001. Information on lifestyle and HBMD (gm/cm2) was collected through a self-administered questionnaire and dual-energy X-ray absorptiometry (DEXA), respectively. Results: Age shows an inverse relationship with HBMD in the subjects. Compared with pre-menopausal women with rare or light exercise, women with moderate exercise had higher HBMD. A higher HBMD was also significantly associated with higher body weight and height. For pri/post-menopausal women, HBMD was positively associated with body height, but was negatively associated with number of years since menstruation ceased. Diet, smoking, and alcohol consumption showed no association with HBMD in both groups. Conclusions: Although the cross-sectional design precludes the causal inference between exercise and HBMD, our data tend to support the beneficial effects of recent exercise, a modifiable lifestyle, on HBMD, which seems to be more noticeable in pre-menopausal women than in peri/post-menopausal women.
