This study was conducted to investigate the factors which are related to Bone Mineral Density(BMD) of female for prevention of osteoporosis. We measured the BMD of lumbar spine(L2-L4) and femoral neck in 4802 female, using dual energy X-ray absorptionmetry(DEXA; DPX-alpha. Lunar, U.S.A.). and then analysed the 9 factors-age group, body mass index(BMI), amount of smoking, drinking, exercise, sleep, and fast blood sugar-which are related to BMD of female. The following results were obtained : 1. In age group, T-score was the highest at 36-42(六七) years group in lumbar spine(L2-L4) and at 15-21(三七) years group in femoral neck. and then it was decreased rapidly after 43-49(七七) years group in both lumbar spine(L2-L4) and femoral neck. Therefore we concluded that T-score of female in lumbar spine(L2-L4) and femoral neck change according to age group in $\ll$Hwangjaenaekyong Somun; 黃帝內經 素問$\gg$. 2. In BMI, T-score of lumbar spine(L2-L4) and femoral neck were increased according to BMI increase. 3. In amount of drinking and smoking, T-score was highest in heavy groups(women who have drunk soju more than 4 bottles for a week) in both lumbar spine(L2-L4) and femoral neck. But there t was no significant difference in comparison according to age group. 4. In exercise, T-score was higher in exercising group than non exercising group. And it appeared that women who have taken proper exercise had higher T-score than women who have taken exercise daily. 5. T-score was higher in women who ordinarily sleep well in both lumbar spine(L2-L4) and femoral neck than sleep badly. And there was significant difference in 43-56 years group. 6. T-score was low in the group that exceed 110mg/dl in fast blood sugar. Conclusions : The age group in $\ll$Hwangjaenaekyong Somun; 黃帝內經 素問$\gg$ is related to BMD of women. And risk factors-BMI, exercise, sleep, fast blood sugar, thyroid disease-are related to BMD of women. Therefore we expect that this study will help for prevention of osteoporosis of women, and further study will be achieved.

The purpose of this study was to find the relationship between osteoporosis and various factors such as general personal background, physical activity, menstruation, daily life and dietary habit. The following are the results of this study: 1. In the relationship of osteoporosis status with general personal background, the risk of osteoporosis increased with age. Active women with higher education, high income and jobs tended to have less risk of osteoporosis. Women with earlier menarche had a tendency of having thicker bone mineral density. 2. As for disease related to bone mineral density, stomach disease, thyroid, bone damage, and bad teeth conditions were significant factors affecting bone mineral density. Women with those diseases and family history of osteoporosis were more likely to have osteoporosis. 3. In relation to food intake regular diet of dairy products, anchovy, or meat showed significantly less risk of osteoporosis. 4. In relation between dietary habits and bone mineral density, unbalanced diet had statistically less probability of osteoporosis. It is important for genetically disposed women to prevent osteoporosis in advance by considering acquired factors like life-style and medication.

Osteoporosis has recently been recognized as a major health problem in the elderly population. The disorder is manifested as a loss of bone mass accompanied by structural alteration of bone and increased incidence of fracture. Mandible also may be affected. So, I evaluated panoramic views of 66 postmenopausal women for finding the possibility of useful diagnostic mandibular parmeters of osteoporosis. To know the correlationship between skeleton and mandible, the average of the bone mineral density of lumbar from 2nd to 4th by the dual energy X-ray absorptiometry(DEXA, LUNAR DPZ. USA), and age and mandibular parameters, that is, the number of residual teeth, alveolar ridge resorption ratio, panoramic mandibular index (PMI), mandibular cortical width (MCW), angular cortical thickness (ACT), ramus cortical thickness (RCT), morphology of mandibular inferior cortical (MIC) were compared. And I divided the all tested women to the osteoporotic group and non-osteoporotic group by the use of T-score -2.0, which was derived from skeletal bone mineral density (BMD). To find the correlationship of the each group with mandibular parameters, t-test and discriminant analysis were done. The results of the t-test were that all parameters were highly related with 2 groups (p<0.05). Especially ACT, MIC, age have had even higher correlationship than others (p<0.001). The results of the discriminant analysis by the use of these ACT, MIC and age were that the discriminant function was Z = -2.973+(-1.447)$\times$(ACT)+1.131$\times$(MIC score)+(0.052)$\times$(age), the cutting score was 0.257 and the classification accuracy was 84.8%. Therefore I suggest that the consideration of the angular cortical thickness (ACT), the age of patient and the morphology of mandibular inferior cortical(MIC) may help find the osteoporosis.
This study identified an effective control method for periodontitis by investigating the association between blood levels of vitamin D and periodontitis in Korean elderly based on raw data from the fifth Korea National Health & Nutrition Examination Survey of 2010 (KNHANES). In this study, 1,021 adults over 65 years of age were evaluated based on data from the KNHANES. Periodontal disease was assessed using community periodontal index (CPI), with CPI codes ${\geq}3$ defined as periodontitis. Blood levels of vitamin D were measured from blood samples and divided into four groups (first quartile: ${\leq}13.23ng/ml$, second quartile: 13.24~16.95 ng/ml, third quartile: 16.96~21.58 ng/ml), and fourth quartile >21.59 ng/ml). Using multiple logistic regression analyses, the variables were adjusted for general characteristics, oral health-related characteristics, health-related characteristics, and bone mineral density. The statistical analysis was performed using the SAS (ver. 9.2). The results of this study are as follows: the prevalence of periodontitis was 42.6% in Korean elderly. After adjusting for general, oral health-related, and health-related, the risk of periodontitis in the first quartile group was 1.74 times (95% confidence interval [CI], 1.02~2.98) higher than that of the fourth quartile group (p=0.041). After adjusting for general, oral health-related, and health-related characteristics as well as bone mineral density, the risk of periodontitis in the first quartile group was 1.73 times (95% CI, 1.02~2.96) higher than that of the four quartile group (p=0.042). There was a significant relationship between blood vitamin D level and periodontitis in Korean elderly. For the prevention of periodontitis, factors related to vitamin D should be considered along with other risk factors.
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$\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). 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.

Objectives: The objective of this study was to investigate analysis of bone mineral density according to Women with low back pain women. Methods: The data were collected from women who visited Physical Examination Center of a Catholic university hospital located in Daegu. Questionnaires were completed by 50 women during the period from July 20, 2000 to January 12, 2001. The sample was divided into three groups(the normal group of 16 cases and the osteopenia group of 12cases and the osteoporosis group of 22 cases). Bone mineral density(BMD) of lumbar spine was measured using energy absorptiometry. Results: The bone mineral density of the lumbar spine decreased with aging. The bone mineral density of the lumbar spine decreased with the serum Calcium and Phosphorus and Alkaline phosphatase increased. The mean bone mineral density of the lumbar spine of healthy women in age(50~59) was 0.87g/$cm^2$, the lumbar spine of women with low back pain in age(50~59) was 0.77g/$cm^2$. In the multiple regression of risk factors to bone mineral density(BMD) of lumbar spine were correlated with age, marriage existence, exercise time, the loving food of taste, calcium, bone mineral density standard T scores(p<0.05). The experience for LBP increased as weight increased(Odds ratio=999.000). The experience for LBP increased as number of Exercise decreased(Odds ratio=999.000). The experience for LBP increased as menopause existence increased(Odds ratio=999.000). The experience for LBP increased as serum Calcium and Phosphorus increased (Odds ratio=999.000). however all four variables had significant no relationship. The correlation in variables in relation to low back pain and bone mineral density, age showed contra-correlation with low back pain existence, Alkaline phosphatase(p<0.01). Weight showed contra-correlation with body mass index(BMI)(p<0.01). Exercise time showed correlation with number of exercise(p<0.01). The loving food of taste showed contra-correlation with Alkaline phosphatase(p<0.05). Bone mineral density showed correlation with menopause existence(p<0.05). Conclusions: Results from this study indicated that a statistically significant association between bone mineral density of the lumbar spin and age, marriage existence, exercise time, the loving food of taste, calcium, bone mineral density standard T scores. In logistic regression test, there were no related variables. The combination of bone mineral density measurement and assessment of the bone turnover rate by measuring biochemical would be helpful for the treatment of patients with risks of osteoporosis. The more precise study for risk factors to osteoporosis is essential.
The purpose of this study is to review the prognosis of the TG Osseotite implant(3i Co, USA) placed in partial edentulous area of oral cavity and to suspect the possible causes leading to failure. 124 TG Osseotite implants that had been inserted between 2000 - 2002 were followed up for 2 years(avg : 9.5 months) in function. Medical records, and radiographs were evaluated and analyzed by the over all success rate, gender and age factor, general disease, implant fixture length and diameter, implant site, bone density, and various surgical methods. Chi square test was used statistically. Of the 124 TG Osseotite implants, 9 implants(7.3%) were removed in early phase and 3 implants(2.4%) were in late phase. The cumulative survival rate was 90.2%. The failure of the TG Osseotite implant was closely related with the use of bone graft techniques such as sinus elevation or immediate implantation and not with the age, sex, general disease, implant site, bone density of implanted site. The failure of the TG Osseotite implant was well developed when it was the wide type of implant and it was inserted for single tooth replacement. The developement of peri-implantitis was the most important factor in the failure of the TG Osseotite implant.
Purpose: This study were to investigate BMD of middle-aged women and to examine the relationships between BMD and Physical, Obstetric characteristics Method: The data was collected from 119 healthy women who were 40-60 years old. they were examined for BMD at 4 regions(forearm, lumbar, femur, whole body), %fat by DEXA and investigated physical, obstetric characteristics using scale, questionnaire from January to March, 2001. Result: 1) According to bone diagnostic results by WHO classification, 95.8% of forearm and whole body BMD were normal but 21.8-48.7% of lumbar and femur BMD(neck, trochanter, ward's triangle) were diagnosed osteoporosis or osteopnea. 2) The bones were significantly positive correlations of each other (r=.19-.69, p=.04-.00) and there were significant correlations between BMD and physical, obstetric characteristics such as age (r=-.22, p=.02), weight(r=.36~.48, p=.00), height(r=.22, p=.02), %fat(r=.19, p=.04) and age of first delivery(r=-.28, p=.00). Conclusion: Based on this study, healthy middle-aged women were also exposed to risk of osteoporosis related to aging, change of physical conditions or hormonal release. Further research to develop nursing interventions for the purpose of preventing osteoporosis by modifying risk factors is suggested.
The objective of this study was to investigate the relation of serum calcium level, body mass index(BMI) with bone status expressed as broadband ultrasound attenuation(BUA) measured by quantitative ultrasound (QUS) and the occurrence of osteopenia among adult men and women. Two hundred eleven(63 male and 148 female) workers who worked in 4 different battery factories were recruited from March 2005 to October 2005. BUA was used as a surrogate of bone mineral density and measured at left calcaneous bone area. The BUA value transformed into T-score by WHO standard conversion criteria to determine osteopenia (-2.5
Postmenopausal women lose more bone mass than men as a result of estrogen deprivation. The resultant low bone mineral density (BMD) is a major risk factor in the development of osteoporosis. Calcium, phosphorus and magnesium are main components of bone. The purpose of this study is to investigate nutrient intake and serum osteocalcin, Ca, P and Mg and their correlation to bone mineral density in Korean postmenopausal women residing in rural areas. We conducted 24 hour dietary recalls, anthropometric measurements and blood analysis on 60 postmenopausal women. The BMD of the lumbar spine (L2$\rightarrow$L4) and the femoral neck were measured by dual energy X-ray absorptiometry (DEXA). Subjects were assigned to one of three groups:normal (T-score> -1, n=20), osteopenia (-2.5> T-score $\leq$ -1, n=23), and osteoporosis ( T-score $\leq$ -2.5, n=17). The mean age, height, weight and BMI were 62.37 yr, 154.36 cm, 55.28 kg and 23.18 $kg/m^2$ respectively. The mean daily energy and protein intakes were 76.35% and 87.41% of RDA for Koreans. The mean intakes of calcium, phosphorus, and magnesium were 463.62 mg (66.23% of RDA), 955.32 mg (136.47% of RDA), 345.87 mg respectively. The mean serum levels of calcium, phosphorus and magnesium were 8.76 mg/dl, 3.80 mg/dl, and 2.10 mg/dl, respectively, and there were no significant differences among the three groups. However, the BMD of the femoral neck showed a significantly negative correlation with serum magnesium (p<0.05). To summarize the results, most nutrient intakes (especially calcium) in postmenopausal women did not reach the RDA values for Koreans. Also, increase of serum magnesium levels may be related to bone loss.
