BACKGROUND
Bone mineral density (BMD) screening guidelines for women younger than 65 years are inconsistent. We investigated BMD-related factors in postmenopausal women younger than 65 years to help clinicians identify which women in this age group should undergo this investigation. METHODS: The study subjects included 108 postmenopausal women, younger than 65 years, who visited one university hospital from January to June 2007 and had a BMD by DEXA. Information on socio-demographic characteristics, menarche, menopause, smoking, alcohol use, past history of fracture and diet were gathered using a self-reported questionnaire. Height and weight were measured. The association between each risk factor and BMD was assessed using Pearson's correlation and ANOVA test. Finally, multiple regression analysis was done, using the model including significant variables of baseline analysis. RESULTS: In our subjects, age was negatively and body weight was positively correlated with BMD of lumbar spine and femur. The reproductive years was positively correlated with BMD of lumbar spine and past history of fragility fracture was negatively associated with BMD of femur. Moderate alcohol users had higher BMDs of lumbar spine and femur. CONCLUSIONS: In postmenopausal women younger than 65 years, age and body weight are major determinants of BMD of lumbar spine and femur, negatively and positively, respectively. Our data suggest women younger than 65 years with low lean body mass, past history of fracture, and premature menopause could be good candidates for BMD. |
