Factors Affecting Bone Mineral Density in Korean Women by Menopause: Hye Bok Na; Korean J Community Nutr 2004;9(1):73-80. Published online February 29, 2004

Abstract PDF: Bone mineral density (BMD) focus one's attention on prevention effects of osteoporosis. This study was conducted to investigate BMD (lumbar spin:L2 - L4, femur neck:FN, femur trochanter:TR, femur ward's triangle:WT, wrist) and look into the factors that affect BMD by menopause in 89 nonsmoking healthy Korean women (40 - 60 yr). Anthropometric index and body composition, nutrient intakes, osteocalcin and total protein, albumin, total cholesterol, triacylglycerol and calcium in serum were determined. Body fat mass, diastolic blood pressure and serum cholesterol concentration of postmenopausal women were significantly higher than those of premenopausal women. FN, TR, WT, wrist BMD of postmenopausal women were not different from those of premenopausal women. However L2 - L4 BMD of postmenopausal women was lower than that of premenopausal women. Significant positive correlations were found between L2 - L4, FN, TR, WT and weight (r = 0.44, r = 0.64, r = 0.58, r = 0.57) and significant positive correlations were found between FN, TR, WT and BMI (r = 0.54, r = 0.45, r = 0.54) of premenopausal women. Whereas significant positive correlation was only found between TR BMD and weight, BMI (r = 0.38, r = 0.29) of postmenopausal women. FN BMD and WC (waist circumstance) of premenopausal women were found significant positive correlation (r = 0.35) whereas L2 - L4 BMD and WC of postmenopausal women was found significant negative correlation (r = -0.31). In premenopausal women, differences of bone BMD were not shown by exercise and alcohol drinking, but in postmenopausal women, significant difference of FN BMD was shown by exercise and alcohol drinking. These results suggested that by menopause, effects of weight, BMI, WC, exercise and alcohol drinking on bone BMD were different. Therefore, by menopause, we should consider the different ways to increase the bone BMD according to different factors.

Factors Affecting Bone Mineral Status of Premenopausal Women: Se In Oh, Hang Shin Lee, Mee Sook Lee, Cho Il Kim, In Soon Kwon, Sang Chul Park; Korean J Community Nutr 2003;8(6):927-937. Published online December 31, 2003

Abstract PDF: This study was conducted to investigate dietary and other factors affecting bone mineral density (BMD) in Korean premenopausal women. Seventy-eight premenopausal women who visited the Health Promotion Center for health examinations volunteered to participate in this study. They were divided into two groups according to their bone status as shown by their T-scores: a non-osteoporotic group and a osteoporotic group. The results are as follows: The mean BMDs of the lumbar spine and femoral neck were 1.21 +/- 0.02 g/cm2 and 0.97 +/- 0.04 g/cm2, respectively. The BMD levels of the osteoporotic group were significantly lower than those of the non-osteoporotic group (p < 0.001, respectively). The heights of the women in the osteoporotic group were significantly lower than those of the non-osteoporotic group (p < 0.01) however, their body weights did not show any significant differences although they tended to be lower. The mean daily intake of energy was 1720 +/- 52 kcal. When the nutrient intake was compared with the Korean recommended dietary allowances (RDA), calcium, Fe, vitamin A and riboflavin intakes were lower than the RDA. Their was no significant difference in the nutrient intake of the non-osteoporotic group and osteoporotic group except for the intakes of protein, fat and niacin. Their was no significant difference between the non-osteoporotic group and the osteoporotic group and all were within the normal range. However, the serum alkaline phosphatase level of the osteoporotic group was significantly higher than that of the non-osteoporotic group (p < 0.001). Height measurements showed positive correlations with lumbar spine bone mineral density (LBMD, r = 0.332, p < 0.01) however there was no correlation with femoral neck bone mineral density (NBMD). Age, age at menarche, body weight, body mass index (BMI) and obesity showed no correlation with BMD. The BMD of the lumbar spine was significantly and positively related to the intake of niacin and vitamin C (r = 0.236, p < 0.05; r = 0.274, p < 0.05). Serum levels of calcium and phosphorus showed negative correlations with LBMD (r = -0.698, p = 0.0001; r = -0.503, p = 0.0001, respectively). The results suggested that the BMD of the lumbar spine was positively related to the intake of niacin and vitamin C in premenopausal women. Therefore, this study confirmed that one of the most effective ways to minimize bone loss would be have a higher intake of niacin and vitamin C rich foods and engaging habitually in physical activity may have a beneficial effect on BMD in the premenopausal period.
