This study was peformed to assess the relationships among bone mineral density(BMD), nutrient intake and lifestyle factors in postmenopausal women. A trained nutritionist examined the interviewed usual dietary intake and physical activity of 85 subjects in Chungnam with a questionnaire interview, and BMDs of the lumbar spines($L_2-L_4$), femoral necks(FN), ward's triangles(WT) and trochanters(TR) were measured by dual energy X-ray absorptiometry (DEXA). The BMDs(T-score) of $L_2-L_4$, FN, and WT were $0.996g/cm^2(-1.601),\;0.697g/cm^2(-1.697)$, and $0.793g/cm^2(-1.512)$, respectively, which were assessed as osteopenia by T-score,. and TR was normal at $0.718g/cm^2(-0.675)$. Subjects included 85 in Chungnam were divided into three groups according to the BMD measurement of the $L_2-L_4$ and FN assessed by T-score. The percentages of the osteoporosis, osteopenia, and normal groups were $32.9\%,\;42.4\%$ and $24.7\%$ respectively. The average age was significantly the highest of the osteoporosis group than in the other two osteopenia or normal groups(P<0.001). Among lifestyle factors, the BMD of lifestyles was significantly related with exercise but it was not significant with medication., salt. intake, bone fracture, coffee consumption, drinking and smoking. The nutrient intake of the subjects was most nutrient intake adequate to the Korean RDA level for most nutrients excepting energy intakes and calcium. The BMD of lumbar spines $L_2-L_4$ showed significant positive association with the intake of most nutrients except carbohydrate, especially in the normal group. The Higher BMD levels were found for those with high intake of protein and vitamin B1. The BMDs of $L_2-L_4$, and FN were positively correlated with showed energy expenditure, exercise, miscellaneous activity, per weekend and week(P<0.05) in normal group but that was showed negatively correlated in the osteopenia group. Therefore, this study confirmed that one of the most effective ways to minimize bone less in postmenopausal women is to maintain an adequate intake of calcium and other nutrients and regular physical activity.
