Objectives : The purpose of this study was to examine the impact of the systemic osteoporosis of Korean adults on their periodontal diseases and CPI index based on the data of their systemic osteoporosis. Methods : The third-year raw data of the 4th 2009 National Health & Nutrition Survey that turned out to be representative and reliable were utilized. The subjects in this study were 7,285 adults who were over the age of 19 and got both of health and dental checkups. As for data analysis, the statistical packages PASW 19.0 and SAS 9.0 were employed. Results : The most periodontal diseases were found in those who had osteoporosis in the entire parts, entire femur, femoral neck and spiral bone, but there was no significant relationship between periodontal diseases and osteoporosis. As for the connections between peridontal diseases and osteoporosis, the adults who had femoral neck osteoporosis had a 2.057-fold less bone mass than those who had a normal bone density in this part, and the former's periodontal diseases increased in proportion to that. There was consequently a statistically significant relationship between the two(p<0.05). Among the prevalence factors of osteoporosis, a lower entire femur bone mineral density led to a lower CPI index(p<0.01), and a lower femoral neck bone mineral density led to a higher CPI index(p<0.05). Thus, there was a significant relationship between osteoporosis and the oral health indicator. Conclusions : The above-mentioned findings confirmed that in terms of the relationship among the periodontal diseases, CPI index and osteoporosis of Korean adults, a higher risk of osteoporosis affected the increase of chronic periodontal diseases.

Nutritional factors affecting bone mineral density (BMD) in the different age groups of Korean men were investigated to obtain baseline data for maintaining bone health. Information on diet and anthropometry was collected in 80 elementary school children, 83 high school students, 87 adults aged 25 to 35 years and 98 elderly people over 60 years of age. Data for food and nutrient intake were obtained by 24-hour recall method. BMDs of lumbar spine (L$_2$- L$_4$) and femoral neck were measured by dual energy x-ray absorptiometry. The relationship between BMD and nutritional factors were analyzed. In the femoral neck, 5.7% of adults was classified as osteopenia and 47.9% and 37.8% of the elderly were classified as osteopenia and osteoporosis. It was shown that plant protein, Ca, p, Fe, thiamin, riboflavin and vitamin C intakes were related with BMD in all age groups. As for the mean adequacy ratio (MAR) of nutrients, the lowest quartile group of BMD showed significantly lower MAR among children. The RDA percent of nutrients was a strong influential factor on BMD. Subjects who consumed below 75% of Korean RDA in energy, vitamin A, thiamin, and vitamin C showed lower BMD. Stepwise multiple regression analysis revealed that MAR in children, vegetable Ca in adolescents, and vitamin C in adults and elderly people were the highest influential factor on BMD. Therefore, the above results demonstrated that not only calcium but also other nutrients such as protein, iron, vitamin A, riboflavin, and vitamin C were necessary in order to keep the healthy bone status. In addition, although there were various dietary factors that influenced bone density, MAR was identified as the major factor that affected bone density. Thus, a balanced diet that includes all nutrients is necessary for a healthy bone density. (Korean J Nutrition 37(2) : 132-142, 2004)

This study was conducted among Korean women over aged 60 who participated in Korea National Health and Nutrition Examination Survey (KNHANES) (the 2nd and 3rd year at the 4th survey, and the 1st year at the 5th survey). The purpose of the study was to figure out a relation between femoral neck and lumbar spine bone mineral density and anthropometry, life style, diet, fracture history, family history of osteoporosis, medical history, menstrual history and reproductive factor. To express the strength of the associations, percent differences were calculated from multiple linear regression models using the formula ${\beta}{\times}$(unit/mean BMD). Unit for continuous variables were chosen to approximate 1 standard deviation(SD). In women aged 60 or older, lean mass(B: 0.257) and fat mass(B: 0.237) greatly influenced bone density in the femoral neck and lumbar spine. Therefore it will be an effective way to prevent osteoporosis for elderly women by increasing lean mass and maintaining proper weight.

Based on an analysis on the difference on the measurement sites and their relations to osteoporosis diagnosis and prevalence, this study attempts to investigate the patterns of prevalence in skeletal sites in the aging process. The samples were driven by the National Health and Nutrition Examination Survey (2008-2010) on Korean females (n = 4,449) aged from 50 to 89 years. The result shows that the differences on affected sites in the aging process were detected as follow: the osteoporosis prevalence in lumbar spine was relatively high in 50s, 60s and 70s; however, the prevalence in the proximal femur (total hip and femoral neck) was higher in 80s. In terms of the diagnosis identified in a single site, the prevalence in lumbar spine seemed to decrease as age increases; but, the rate went up in the figure of femoral neck. Overall, the osteoporosis prevalence for the diagnosis detected in multiple sites was increased as age goes up. In general, the increase in lumbar osteoporosis prevalence starts earlier than that of femoral neck. The findings of this study also suggests that if the proximal femur site is only used for diagnosing women age in 50s, 60s and 70s, the significant portion of osteoporosis patients could be misdiagnosed as normal.

The purpose of this study was to evaluate the nutrient intake, diversity and prevalence of diseases according to noodle consumption using data from the Korean National Health and Nutrition Examination Survey (KNHANES) of 2010. Korean adults (>20) were classified into two groups, noodle group (NG) and non-noodle group (NNG). NG was found to have higher intakes of protein, calcium, iron, sodium, potassium, and niacin. The DVS and DDS according to noodle consumption were found to be 21.76 and 3.51 for NG, and 18.56 and 3.40 for NNG, this result was thought to show that the diet of NG was more satisfactory than that of NNG in terms of dietary diversity. In the bone mass of entire subjects, NG showed higher figures in the femoral neck and lumbar spine than NNG. For bone mineral density, NG exhibited higher figures in the femoral neck, and for T-scores, the values of NG was significantly higher in the femoral neck than those of NNG. However, the prevalence of osteoporosis of NG and NNG was 11.6% and 9.5%. The prevalence of osteopenia of NG and NNG was 43.0% and 51.7%. Thus, these results showed that overall bone health of NG was better than that of NNG. Dietary balance and quality were also more satisfactory in NG. These results showed that noodle consumption may have an impact on the prevalence of chronic diseases.

Purpose: This study was to examine the effectiveness of exercise for bone mineral density (BMD). Methods: Four investigators reviewed English articles from Pub Med and CINAHL, selecting randomized controlled trials on exercise programs for middle-aged and older women. Out of 25 studies identified, 14 that satisfied with the inclusion criteria were included in the meta-analysis. The quality of the studies was assessed using recognized methods and the effect size was calculated as a Hedges'g using Comprehensive Meta-analysis Version 2.0. Primary outcomes were changes in BMD at femoral neck, trochanter, and lumbar spine. Subgroup analysis included changes in BMD according to exercise style. Results: Weight bearing exercise was effective(Q=20.1, p>.05, ES=0.32), and resistance exercise was effective in case of comparing to pre and post intervention (Q=4.15, p=.98, ES=0.14). At the femoral neck, 9 study groups were homogeneous and the experimental groups demonstrated a positive effect on BMD (Q=19.5, p>.05, ES=0.33). In contrast, marked heterogeneity (Q=33.3, p<0.01) was apparent in 7 study groups evaluating trochanter. Conclusion: These findings suggest that weight bearing is effective for BMD of the femoral neck, and is relevant to the non-pharmacological treatment of bone loss for middle-aged and older women.

Purpose: To evaluate the treatment result in polyostotic fibrous dysplasia classified according to the involvement of the femoral head. Materials and Methods: Twenty-three patients from March 1987 to March 2014 were reviewed retrospectively. Patients with no involvement of the physeal scar in the femoral head were classified as Type I, and those with involvement of the physeal scar were classified as Type II. A plain radiograph was used to measure the femoral neck shaft angle, articulo-trochanteric distance (ATD), and anterior bowing through the lateral view. A teleoroentgenogram of the lower limb was used to measure the leg length discrepancy and lower extremity mechanical axis. The pre- and postoperative femoral neck-shaft angle and ATD were compared to assess the degree of correction of the deformity. Results: Among a total of 46 cases (23 patients), 28 cases (23 patients) had lesions in the proximal femur. Type I were 16/28 cases (15/23 patients) and Type II were 12/28 cases (9/23 patients). The preoperative proximal femoral neck-shaft angle was 116.8° in Type I and 95.3° in Type II. The ATD was 12.08 mm in Type I and -5.54 mm in Type II. The deformity correction showed significant improvement immediately after surgery, the deformity correction was lost in Type II (neck shaft angle Type I: 133.8°-130.8°, Type II: 128.6°-116.9°, and ATD Type I: 17.66-15.72 mm, Type II: 7.44-4.16 mm). The extent of anterior bowing was 12.74° in Type I and 20.19° in Type II. The mean differences of 12 mm between the 9 patients who showed a leg length discrepancy and the lower extremity mechanical axis showed 4 cases of lateral deviation and 7 cases of medial deviation. Conclusion: In polyostotic fibrous dysplasia, when the femur head is involved, the femur neck shaft angle, ATD, and anterior bowing of the femur had more deformity, and the postoperative correction of deformity was lost, suggesting that the involvement of the femoral head was an important factor in the prognosis of the disease.

In this study, three different devices, Norland, Osteocore and Lunar were used to compare and analyze the measurement error by each bone density measurement device by classifying the physical characteristics into age, height and weight, the subject of total 300 sampling 100 persons for each device. Categorizing Lumbar region and Femoral neck as normal (T-score$\geqq$-1.0), osteopenia (-1.0>T-score>-2.5) and osteoporosis (T-score$\leqq$-2.5), the findings were observed as follows. Norland device showed the least measurement error in age and height, while Lunar showed the least in weight among the devices. And, the result of comparing the bone density measurement error based on the lumbar region showed that all of Lunar, Norland and Osteocore have the least variation of measurement error in osteopenia and the result of comparing based on the femoral neck showed that all of Lunar, Norland and Osteocore have the least variation of measurement error in osteoporosis. For each variable, the measurement error was observed to be vary upon the device. To solve this, standardized common Phantom should be used to compare and converge the measured value of each company and cross-calibration would be necessary when replacing the software.

Background: Examination of the effects of deer antler, old antler, and antler glue on postmenopausal osteoporosis in an ovariectomized Sprague-Dawley rat model. Methods: The study involved 7 experimental groups; SHAM (sham-operated rats), OVX (ovariectomized rats), E2 (ovariectomized rats with estradiol $10{\mu}g/kg$ daily, orally), DA (ovariectomized rats with deer antler extract 5.83 mg/kg), OA (ovariectomized rats with old antler extract 3.8 mg/kg), low-AG (ovariectomized rats with low dose of antler glue powder 12.5 mg/kg), high-AG (ovariectomized rats with high dose of antler glue powder 37.5 mg/kg). After 6 weeks of treatment, body weight, blood calcium, phosphorus, estradiol, liver [alkaline phosphatase (ALP), aspartate transaminase (AST), alanine transaminase (ALT)] and kidney [blood urea nitrogen (BUN)/creatinine ratio] function, and femoral bone mineral density (BMD) were measured. Results: The body weights of DA, OA, low-AG, and high-AG groups did not significantly differ from OVX group. Blood estradiol levels were significantly increased in the DA, low-AG, and high-AG groups compared to the OVX group. Blood calcium, phosphorus, ALP, AST, and ALT levels and BUN/creatinine ratio did not show significant changes in the DA, OA, low-AG, and high-AG groups. BMDs of the femur, and femoral head and neck were significantly increased in the low-AG group. In the OA group, the BMD of the femoral head and neck was significantly increased. Conclusion: Treatment with deer antler, or antler glue for 6 weeks was effective for increasing estradiol and femoral BMD in ovariectomized rats, suggesting that this may be of therapeutic benefit for osteoporosis.

This study was conducted to test the effect of brisk walking & muscle strengthening exercise program on bone mineral density(BMD) of the lumbar & femur in rheumatoid arthritis women. Research design was a quasi-experimental study of non-equivalent control group pretest-posttest design(16 weeks). 14 for the experimental group and 14 for the control group were selected from the outpatients on rheumatoid arthritis clinic of Dong-A University Hospital. The experimental group underwent 16 weeks of brisk walking and muscle strengthening exercise. Bone mineral density was measured before and after 16 weeks of exercise by DXA at lumbar spine, femoral neck, Ward's triangle and trochanter. The results were summarized as follows : 1. BMD of the lumbar spine in experimental group who carried out the brisk walking and muscle strengthening exercise was not significantly increased after 16weeks and there was no significant difference between experimental and control group(U=70.00 p>.05). 2. BMD of the femoral neck in the experimental group who carried out the brisk walking and muscle strengthening exercises was significantly increased after 16 weeks(Z=-2.901 p<.01). But, there was no significant difference between experimental and control group(U=83.00 p>.05). 3. BMD of the femoral Ward's triangle in the experimental group who carried out the brisk walking and muscle strengthening exercises was significantly increased after 16 weeks (Z=-2.355 p<.05). But, there was no significant difference between experimental and control group(U=86.00 p>.05). 4. BMD of the femoral trochanter in experimental group who carried out the brisk walking and muscle strengthening exercise was not significantly increased after 16weeks and there was no significant difference between experimental and control group(U=75.00 p>.05). These results suggest that brisk walking and muscle strengthening exercise program has an effect on promoting bone mineral density of femoral neck and Ward's triangle in rheumatoid arthritis women.
