  • This study was conducted to investigate osteopenia and osteoporosis prevalence of radius and tibia using Quantitative Ultrasound (QUS) and to identify affecting factors of osteoporosis. A total of 4,340 women aged 40 - 69 years, living in Ansung (rural) and Ansan (mid-sized) area, and free of illnesses affecting bone metabolism participated in the community-based cohort study. Among them 4,059 subjects measured radius bone density and 4,089 measured tibia. The T-score threshold, defined as < -1.0 and $\le$-2.5, was used to identify subjects with osteopenia and osteoporosis by WHO criteria. The crude prevalence of osteoporosis in radius and tibia was $8.4\%$ and $23.3\%$ respectively; after adjustment for age, it changed $6.3\%$ and $18.8\%$. In simple logistic regression analysis, the prevalence of osteoporosis increased by aging, non-marital status, low education, low income. Otherwise, high intakes of Ca/P, thiamin, riboflavin, vitamin B6, and vitamin E were decreased osteoporosis prevalence. Compared to the normal BMI (body mass index) group 08.5 $\le$ BMI < 23), the odds ratio (ORs) of the low BMI group (BMI < 18.5), and high BMI groups (BMl25-30, BMI $\ge$ 30) were significantly increased. The OR of osteoporosis decreased across increasing quartiles of intakes of Ca, P and Ca/P. Therefore, maintaining normal BMI and increasing Ca intake and Ca/P ratio may have a beneficial effect on bone health of Korean women.

  • Statistical analysis was performed on the patients who took bone densitometry using Lunar and Hologic equipments for 5 months from January $1^{st}$ 2010 to May $30^{st}$, 2010. Patients consisted of 50 in their 40s, 100 in 50s and 50 in 60s. In addition, the results from bone densitometry were carried out on the same subject with two equipments on the same day. In case of 200 subjects, who received the bone densitometry with two equipments, the average age was 54.5 and 54.4 years old, respectively. There was no difference. The T- score of Lunar equipment was $-1.377{\pm}1.221$ and that of Hologic equipment was $-1.806{\pm}1.123$. The T-score of Lunar equipment was measured higher than that of Hologic equipment. T-test was conducted to determine the equality of the mean of two groups with 200 patients. Since the pvalue was 0.000, the value of bone mineral density was significant in two equipments. Furthermore, the patients, who were diagnosed by Lunar, showed more 'normal' and who were diagnosed by Hologic, showed more osteoporosis, which cartegorized by WHO, such as normal, osteopenia, and osteoporosis. Thus, compared results of bone densitometry on lumbar spine L1 - L4 of four normal people with the same equipment showed that T- score of Lunar equipment was $-0.4{\pm}1.2$, and T- score of Hologic equipment was $-1.1{\pm}1.5$. It showed the higher T- score was measured in Lunar equipment as well. Therefore, the correction factor should be considered to use, since T- scores are different between two equipments.

  • Several nutrients are known to affect bone mineral density (BMD). However, these nutrients are combined with food intake and dietary patterns and little is known about the association of dietary patterns and BMD. The objective of this study was to investigate the association of dietary patterns with BMD in Korea Genome Epidemiology Study subjects. Among 2,884 women (40-69 yr) recruited at baseline study (2001), 861 subjects with BMD measurements at baseline and a 4-year follow up study (2005) completed the semi-quantitative food frequency questionnaire. BMD was measured by the Quantitative Ultrasound method. One hundred three food items were combined into 17 food groups and 4 dietary patterns were identified by factor analysis. Cluster analysis using factor score classified each subject into one of three dietary pattern groups named 'Rice and kimchi eating' (n = 617), 'Contented eating' (n = 124), and 'Healthy and light eating' (n = 120). The 'Healthy and light eating' group, characterized by higher intake of fruit, vegetables, fish, milk and dairy products, and younger age, more exercise, higher education, and higher income than other groups. The tibia BMD of the 'Healthy and light eating' group was higher than the other groups after adjusting for the age. After the adjustment for the age BMI and exercise, the 'Healthy and light eating' group showed significantly lower odds of tibia osteopenia/osteoporosis risk compared to the 'Rice and kimchi eating' group both at the baseline [OR(95% CI) : 0.50(0.30-0.84)] and follow-up [OR(95% CI) : 0.59(0.36-0.97)] examinations. The dietary pattern with low calorie and high intakes of fruit, vegetables, fish, milk and dairy products may have beneficial effects on BMD in middle-aged women.

  • The purpose of this study was to analyze the effects of ballet program training at the Royal Academy of dance (RAD) on body composition (BC), physical fitness (PF) and bone mineral density (BMD) in college women. The subjects for this study were 14 females aged 19 to 22, who were divided into the Experimental group (n=7, EG) and the Control group (n=7, CG). The RAD ballet program training was done by 7 subjects (EG), 60 minutes per day, three times a week for 12 weeks. The TBF and %fat significantly decreased and LBM increased in the Experimental group, but all the variables of Body composition in the Control group did not significantly changed. The AMS, Sit ups, STF, SLJ CFB and 1,200 m R & W in the EG significantly increased, but 1,200 m R & W in the CG decreased. The lumbar vertebra (LV), femoral neck (FN), greater trochanter (GT) and ward's triangle (WT) did not significantly change in the EG, but LV, GT and WT in the CG decreased. There was no significant difference in osteopenia for EG, but there were increases in GT and WT for the CG. There was significant correlation between BMDs and body weight, TBF, LBM, %fat, BMI, AMS. There was significant correlation between LV and FN and LV and whole body. In conclusion, regular and continuous RAD training was effective in improving the body composition, physical fitness and bone mineral density. Consequently, RAD training will be effective for preventing osteopenia and osteoporosis, and for improving the health-related fitness for college and middle-aged women.

  • This study examined the impact of osteoporosis on thyroid hormone in health check-up examinees. The study subjects were 1,117 adults, 20 years and over (636 males, 481 females), who underwent a health package check-up at the general hospital G from January to December, 2011. After adjusting for factors, such as year and gender, the mean thyroid stimulating hormone increased with decreasing T-score (Normal[${\geq}-1g/cm^2$], $1.61{\pm}0.07{\mu}IU/m{\ell}$ and osteopenia[-1 >, ${\geq}-2.5g/cm^2$],$1.82{\pm}0.08{\mu}IU/m{\ell}$ and osteoporosis[< $-2.5g/cm^2$],$3.14{\pm}0.27{\mu}IU/m{\ell}$). After adjusting for factors, such as gender and FBS, the mean free thyroxine decreased with decreasing T-score(Normal, $1.30{\pm}0.01ng/d{\ell}$, and osteopenia, $1.22{\pm}0.01ng/d{\ell}$, and osteoporosis, $1.13{\pm}0.04ng/d{\ell}$). Conclusion. These results suggest that a decrease in T-score might increase the thyroid stimulating hormone and decrease the free thyroxine levelin euthyroid adults.

  • The factors affecting bone mineral density (BMD) of 103 rural women aged 30 to 76 years were investigated. Data for food and nutrient intake was obtained by 24-hour recall method. BMD of lumbar spine(L1-L4), femoral neck, ward's triangle and trochanter was measured by XR-series x-ray bone densitometer. Serum was collected and analyzed for total Ca, P and ionized Ca (Ca++)content. Relationship between the factors and BMDs was analyzed by Pearson's correlation coefficient(r) and multiple regression analysis. The results are summarized as follows. 50% of the subjects under 50 years of age($\leq$49 yr group) and 86.4% of the subjects from 50 up($\geq$50yr group) were classified as osteopenia or osteoporosis. Mean body weight, height and BMI were 153.1cm, 59.1kg and 25.0kg/$m^2$ in $\leq$49 yr group and 151.9cm, 55.9kg, and 24.2kg/$m^2$ in $\geq$50 yr group. BMDs of lumbar spines and femurs ranged from 0.84 to 1.05g/$m^2$ and from 0.67 to 1.16g/$m^2$ in $\leq$49 yr group, and ranged from 0.67 to 0.85kg/$m^2$ and from 0.68 to 0.44g/$m^2$ in $\geq$50 yr group, respectively. On the whole, the BMDs were reduced to 83.8 to 94.2% of peck bone mass in $\leq$49 yr group and 55.2 to 78.9% of those in $\geq$50 yr group. Mean daily intake of Ca was much less than the Korean RDA, \67.2% in $\leq$49 yr group and 62.3% in $\geq$50 yr group. The average concentration of total Ca, P and Ca++ in serum were within normal range in both age group. Both age and height were significantly related with BMD in both age group but the relationship tended to be stronger in $\geq$50 yr group than in $\leq$49 yr group. Body weight was also a potent determinant of BMD only in 50 yr group. In $\leq$49 yr group, total food intake was positively related with BMDs of ward's triangle, L1 and L2 and intake of cereals and grain products, sugars and sweets, milk and dairy products was positively related with BMDs measured in this study. On the contrary, intake of eggs, oil and fats were positively related with a few BMDs in 50 yr group. The BMDs were positively affected by intake of energy, protein, carbohydrate, Ca, P and Fe in $\leq$49 yr group and those of protein, fat Ca, P, vitamin B1, vitamin B2 and vitamin C in $\geq$50 yr group. It was noteworthy that serum Ca++ concentration was positively related with BMDs of lumbar spine in boty age groups. According to multiple regression analysis, the four factors, age, body weight, height and BMI additionally accounted for 21% of the variance in BMD of trochanter in $\leq$49 yr group and only two factors, age and C a intake accounted for 38% of that of femoral neck in $\geq$50 yr group. Further investigation is necessary to make sure of the relations between BMD and serum Ca++ level.

  • Type 1 diabetes mellitus (T1DM) is a pathological condition associated with osteopenia. $WNT/{\beta}$-catenin signaling is implicated in this process. Trabecular and cortical bone respond differently to $WNT/{\beta}$-catenin signaling in healthy mice. We investigated whether this signaling has different effects on trabecular and cortical bone in T1DM. We first established a streptozotocin-induced T1DM mouse model and then constitutively activated ${\beta}$-catenin in osteoblasts in the setting of T1DM (T1-CA). The extent of bone loss was greater in trabecular bone than that in cortical bone in T1DM mice, and this difference was consistent with the reduction in the expression of ${\beta}$-catenin signaling in the two bone compartments. Further experiments demonstrated that in T1DM mice, trabecular bone showed lower levels of insulin-like growth factor-1 receptor (IGF-1R) than the levels in cortical bone, leading to lower $WNT/{\beta}$-catenin signaling activity through the inhibition of the IGF-1R/Akt/glycogen synthase kinase $3{\beta}$ ($GSK3{\beta}$) pathway. After ${\beta}$-catenin was activated in T1-CA mice, the bone mass and bone strength increased to substantially greater extents in trabecular bone than those in cortical bone. In addition, the cortical bone of the T1-CA mice displayed an unexpected increase in bone porosity, with increased bone resorption. The downregulated expression of WNT16 might be responsible for these cortical bone changes. In conclusion, we found that although the activation of $WNT/{\beta}$-catenin signaling increased the trabecular bone mass and bone strength in T1DM mice, it also increased the cortical bone porosity, impairing the bone strength. These findings should be considered in the future treatment of T1DM-related osteopenia.

  • Purpose: This study was performed to assess the relationships among bone mineral density, dietary habits, life styles and anthropometric measurements in young women. Subjects included 229 female college students in Seoul and Kyunggi province. Method: The subjects were asked about dietary habits and life styles using questionnaire. A sampel of 229 young women was assessed anthropometric measurements and bone mineral density on calcaneous using quantitative ultrasound. Result: The percentages of the osteoporosis(T-score<-2.5), osteopenia(-2.5${\leq}$T-score<-1.0), and normal(T-score${\geq}$-1.0) groups were 1.75%, 13.53% and 84.71%, respectively. Weight, soft lean mass, and BMI were positively related with T-score and Z-score. But height was negative related with SOS(Speed of sounds). Conclusion: This study confirmed that one of the most effective ways to minimize bone mineral density less in young women is to maintain an adequate body weight, soft lean mass, and BMI. And the young women were recommended do not one-side eating, daily intakes of milk products, perform daily physical exercise, and do not drink coke or soft drinks for the bone health.

  • Brown tumors also called as osteoclastomas, are rare nonneoplastic lesions that arise in the setting of primary or secondary hyperparathyroidism. Parathyroid adenomas or hyperplasia constitute the major Brown tumor source in primary hyperparathyroidism while chronic renal failure is the leading cause in secondary hyperparathyroidism. Most of the patients with the diagnosis of primary hyperparathyroidism present with kidney stones or isolated hypercalcemia. However, nearly one third of patients are asymptomatic and hypercalcemia is found incidentally. Skeletal involvement such as generalized osteopenia, bone resorption, bone cysts and Brown tumors are seen on the late phase of hyperparathyroidism. The symptoms include axial pain, radiculopathy, myelopathy and myeloradiculopathy according to their locations. Plasmocytoma, lymphoma, giant cell tumors and metastates should be ruled out in the differential diagnosis of Brown tumors. Treatment of Brown tumors involve both the management of hyperparathyroidism and neural decompression. The authors report a very rare spinal Brown tumor case, arisen as the initial manifestation of primary hyperparathyroidism that leads to acute paraparesis.
