Purpose: To evaluate physical characteristics, lifestyle related to bone-health, and bone mineral density (BMD) in mothers and their daughters and to determine the predictors of BMD. Method: BMDs at the forearm, lumbar spine, and femur were measured in 101 healthy, mother-daughter pairs by dual energy X-ray absorptiometry. Mother-daughter differences between general characteristics, means for BMDs were assessed by ${\chi}^2$-test, t-tests. Multiple regression analyses were used to identify predictors of BMD in each group. Results: Mothers had significantly higher BMD than their daughters at forearm, lumbar spine, and femur. The predictors of mothers' BMDs were body weight, body mass index (BMI) and percentage body fat, explaining 5.1~31.6% of the variation in BMDs. BMI, percentage body fat and their mother's BMD of the corresponding site bone were predictors in daughters, explaining 17.5~31.6% of the variations in BMDs. Conclusion: These results indicate the importance of weight on bone that the BMDs seems to be related to fat free mass both in young-adult daughters and in middle aged mothers. These also suggest the importance ofintervention for the development of BMD in daughter of mother with low BMD.

Purpose : This study was carried out to evaluate correlation between Bone Mineral Density(BMD) and degenerative lumbar disease in postmenopausal low back pain patients. Methods : 69 postmenopausal patients with low back pain were examined. Magnetic resonance imaging was performed to evaluate degenerative lumbar disease and bone mineral density of lumbar spine was measured by Dual energy X-ray absorptiometry. Data were analyzed by Pearson's Linear Correlation Coefficient. Results : In postmenopausal patients with low back pain, BMD(T-score, Z-score) had negative correlation with the grade of intervertebral disc herniation and positive correlation with weight. Other lumbar diseases including Spinal stenosis, Spondylolisthesis and Facet joint arthrosis didn't have significant correlation with BMD. Conclusion : In postmenopausal patients with low back pain, BMD(T-score, Z-score) had inverse relationship with the grade of intervertebral disc herniation.

The purpose of this study is to analyze the cost-effectiveness of four medications for treating and preventing osteoporosis -HRT therapy(conjugated equine estrogen 0.625mg for 25 days and medroxyprogesterone acetate 5mg for 01112 days), Alendronate(10mg and 5mg), Active Vitamin D(Calcitriol), and Calcium. Total costs include the direct medical cost -examination fee, consultation fee, prescription fee, fee for preparing medications, and the price of pharmaceuticals- and the indirect cost of patients such as traffic expenses and time cost. In addition, the costs of monitoring in adverse reactions are added. The effects of four medications are expressed as BMD(Bone Mineral Density) percent change measured by DEXA(Dual Energy X-ray Absorptiometry) in lumbar spine(L2-L4) and femoral neck site. A mixed model based on meta analysis provides the estimates of effectiveness, which are then appled to the hypothetical cohort consisting of postmenopausal women at the age of 50-59. HRT therapy is the most cost-effective medication at 172,433.64 won (lumbar spine site) and 546,328.28 won (femoral neck site) per BMD percent change for osteoporosis. Alendronate 10mg is more cost-effective than Alendronate 5mg as 345,971.23 won and 378,441.63 won per lumbar BMD percent change at 0.991ｇ/$cm^2$, respectively. Alendronate 10mg is more cost-effective than Alendronate 5mg as 1,329,257.89 won and 1,467,291.23 won per femoral neck BMD percent change at 0.834ｇ/$cm^2$, respectively.

The objectives of this study were to obtain normative data for 45 mother-daughter pairs on spine, femur(neck, ward's triangle, trochanter) and total body BMD (bone mineral density) measured by dual energy X-ray absorptiometry, anthropometric measurement, body composition, biochemical markers, nutrient intakes and energy expenditure, to determin the interrelations of these factors within each group, to measure familial resemblance for each variable. We observed significantly positive correlations between height, weight, head, hip and calf circumferences, tricep, femur and calf skinfold thickness, total lean body mass(=weight-total fat body mass-bone mineral content), protein and fat intakes, Ca index, serum total protein and albumin of monter-daughter pairs(p<.05-p<.001). Among mothers, age, osteocalcin, higher, weight, Ca and energy intakes were predictors of BMDs. Among daughters, weight and energy intake were predictors of BMDs. The BMD in lumbar spine(r=.48, p<.01), femoral neck(r=.38, p<.05), ward's triangle(r=.36, p<.05) of the mothers were significantly correlated with those of the daughters, after adjustment for mother's age, hight, weight, osteocalcin, Ca and energy intakes and daughter's weight, energy intake. In regression analyses, mother's BMD also were positively associated with daughter's BMD in lumbar spine, femoral neck, ward's triangle. Our findings support that mothers with low BMD tended to have daughters with low BMD. In the age groups studied, as well genetic factors as environmental factors may have an important role in determining BMD. This study suggests that women may successfully enhance their genetically determined BMD through adequate nutrient intakes and weight bearing exercise.

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 health promotion center for health examinations volunteered to participate in this study and they were divided into two groups according to the bone status by T-score : normal or osteopenic group and osteoporotic group. The demographic and general characteristics, and dietary intake were surveyed using the questionnaire. BMDs of the lumbar spine and femoral neck of subjects were measured by dual energy X-ray absorptiometry. Serum samples were measured for Lipid concentration, and calcium, phosphorus, alkaline phosphatase as bone formation indicators. Urine was analysed for creatinine as bone resolution indicators. The results are as follows:The mean BMDs of the lumbar spine and femoral neck were 1.21 0.02g/cm$^2$ and 0.97 0.04g/cm$^2$, respectively and the BMD levels of osteoporotic group were significantly lower than that of normal or osteopenic group (p<0.001, respectively). Height in osteoporotic group was significantly lower than that of normal or osteopenic group (p<0.01), and bodyweight did not show any significant difference but had a lower tendency. Mean daily intake of energy was 1720 52ka1. When nutrient intake was compared with recommended dietary allowances (RDA) of subjects, calcium, Fe, vitamin A and riboflavin intakes showed means lower than RDA. The nutrient intake did not show any significant difference between normal or osteopenic group and osteoporotic group except intakes of protein fat and niacin. Serum and urine levels did not show any significant differences between normal or osteopenic group and osteoporotic group and all were within normal range, however, serum alkaline phosphatase level of osteoporotic group was significantly higher than that of normal or osteopenic group (p<0.001). Height showed positive correlations with lumbar spine bone mineral density (LBMD, r=0.332, p<0.01), no correlation was found with femoral neck bone mineral density (NBMD). Age, age at menarche, bodyweight, 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 a negative correlation with LBMD (r=-0.698, p=0.0001; r=-0.503, p=0.0001, respectively). The results suggested that the BMDs 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 way to minimize bone loss would be higher intake of niacin and vitamin C rich foods and habitual physical activity may have a beneficial effect on BMD in premenopausal period.

This study was conducted with 20 female gymnasts and 23 age-matched controls to examine the relationship of diet, menstrual function and bone mineral density (BMD). The results obtained are summarized as follows : Energy intake of gymnasts was 968.9$\pm$421.4kcal, and energy expenditure was 2091.4$\pm$361kcal showing negative energy balance(-1,122.5$\pm$534.6kcal). The average intakes of calcium, iron, vitamin A, thiamin, riboflavin and niacin did not meet the Recommended Dietary Allowances for their age groups. Mean age at menarche in gymnasts is 15.8$\pm$1.2 years compared with 11.8$\pm$2.8 years in age-matched controls. The profile of estradiol, progesterone, and luteinizing hormone was lower than age-matched controls but not significant. Athletic amenorrheic gymnasts(n=12) have the menstrual irregularity(n=10) and amenorrhea(n=2). A number of variables as such nutritional deficiency in diet, negative energy blasnce and hypogonadotropic hormonal status were included. The bone mineral density (BMD) of female gymnasts were significantly higher than controls for the lumbar neck(p<0.001), trochanter(p<0.01), and Ward's triangle(p<0.001), but there were no significant differences for the lumbar spine and forearm. The lumbar spine BMD had a positive correlation with age and lean body weight. The femoral neck BMD was significantly associated with age, group and lean body mass. The trochanter BMD had significant relationship with group, body mass index, energy expenditure and follicular stimulating hormone. Ward's triangle BMD were related to body mass index and follicular stimulating hormone. The significant association was deterced between forearm BMD and age and lean body weight. The major finding of this investigation is that the BMD of gymnasts were higher than age-matched controls despite the fact that gymnasts as a group had inadequate dietary calcium and a higher propensity to have an interruption of their menstrual cycle. These data indicate that grymnsts involved in sports producing significant impact loading on the skeleton had greater femoral neck, trochanter and Ward's triangle bone density than age-matched controls.

The objective of this study is to examine the factors affecting bone mineral density in pre- and postmenopausal women. The subject were 30 Korean premenopausal women with mean ages of 33.6 years, and 30 Korean post menopausal women with mean ages of 63.3 years without diagnosed diseases. Data for food and nutrient intake were obtained by the24-hour recall method. BMD of lumbar spine and femoral neck were measured by the dual-energy X-ray absorptiometry (DEXA). Anthropometric measurement were made, and a blood sample was taken for assay osteocalcin. The results are summarized as follows: 16.67% of the subjects in the premenopausal women and 87.33% of the subjects in the postmenopausal women was less than the korean RDA level exceping phosphorus and vitamin C. In the premenopausal women, BMD of lumbar spine is correlated significantly with anthropometric measurement such as weight, waist circumference, BMI, and body fat mass BMD of femoral neck for the premenopausal women is correlated significantly with weight, BMI, waist circumference, body fat mass, hip circumference, and BMDs of both site are negatively correlated with lean body mass, total body water, but they are not related with intake of nutrients in this study. In the postmenopausal women group, BMDs of both site are not significantly correlated with anthropometric measurement, but BMD of lumbar spine showed positive relation with intake of energy, protein, and carbohydrate. In conclusion, adequate nutrient intake, especially energy, protein have been suggested to prevent the loss of bone mineral density in the postmenopausal women. Also, adequate body weight and BMI have been suggested in the 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$\pm$0.02$g/cm^2$ and 0.97$\pm$0.04$g/cm^2$, respectively. The BMD levels of the osteoporotic group were significantly lower than those of the non-osteoporotic group (p<0.001, respectively). The heights of the women in the osteoporotic group were significantly lower than those of the non-osteoporotic group (p<0.01) however, their body weights did not show any significant differences although they tended to be lower. The mean daily intake of energy was 1720$\pm$52㎉. 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).

Higher bone mineral density (BMD) at a young age, calcium intake, and exercise are important for prevention of osteoporosis later in life. We examined familial effects of BMD between mothers and children and adolescents aged 8-19 in Cheonan, Korea and the relationships between BMD and lifestyle parameters, including: food and nutrient intake and exercise. For daughters and sons, significant differences in BMD were observed at the three bone sites (total femur, femur neck, and lumbar spine) according to age, gender, body mass index, exercise, and milk consumption, compared to the reference value for each classification category. Mean differences in children's BMD were observed according to maternal BMD. Energy and calcium intake were lower in both children and mothers in comparison to the estimated daily energy requirement; however, their protein intake was much greater than the daily recommended intake. After adjusting for age and gender and for mother's age, body mass index, and total calorie intake, results of the food frequency test showed an association of a higher intake of meat, meat products, milk and milk products with greater BMD of total femur, femur neck, and lumbar spine of children. In addition, exercise was positively associated with higher BMD. Regression analysis showed a positive association of BMD with age, male gender, exercise, and mother's BMD. In conclusion, after adjustment for environmental parameters, maternal BMD had a positive influence on BMD in daughters and sons. This finding suggests that parents need to check their BMD in order to determine whether their children are at increased risk of low BMD.
