Purpose: This study was conducted to identify factors related to osteoporosis prevalence in postmenopausal women. Methods: This study was a secondary analysis research using data from the Eighth Korea National Health and Nutrition Examination Survey (KNHANES VIII-1), 2019, which were downloaded from the KNHANES website. The subjects of this study were 1,791 postmenopausal women who participated in the KNHANES VIII-1, 2019. Data analysis was performed using the IBM SPSS 21.0 program and complex sample design analysis was performed considering factors such as weight, cluster, and strata. Results: Osteoporosis prevalence of in postmenopausal women was 17.5%. Factors related to osteoporosis prevalence were age (65~74 years old, ≥75 years old), house income (low), household type (one-person household), postmenopausal period (10~19 years), drinking (non-drinking). Conclusion: Interventions for osteoporosis prevention and management in postmenopausal women need to focus on women less than 10 years after menopause and one-person household women. Furthermore, it is necessary to expand bone density testing for the early detection of osteoporosis in postmenopausal women.

Background: In postmenopausal women, there is rapid bone loss due to estrogen depletion. In women, reproductive factors such as age at menarche, breastfeeding, and parity are considered risk factors of osteoporosis. Many reports suggest that obesity is associated with a reduced risk of osteoporosis. This nationwide, population-based study aims to identify the association between maternal age and osteoporosis risk in postmenopausal women of different obesity classifications. Methods: We assessed data from the Korean National Health and Nutrition Examination Survey 2010-2012. The study included 1,328 postmenopausal women, after excluding women with missing data for reproductive history among 4,546 postmenopausal women in the survey. Multivariate regression was used to identify the association between childbirth age and postmenopausal bone mineral density after adjustments for confounding factors. Results: The prevalence of postmenopausal osteoporosis was 35.24% (n = 468). After dividing the subjects into obese and non-obese groups based on body mass index (BMI) and waist circumference, there were significant differences between non-osteoporosis and osteoporosis groups with regard to age at first childbirth, age at last childbirth, and parity in the BMI-based general obesity group. The prevalence of osteoporosis was highest in women older than 35 years old at last childbirth. The prevalence of osteoporosis was also greater in women with parity ${\geq}4$ compared to those with lower parity levels. Conclusion: Postmenopausal women of older age at last childbirth and higher parity were at increased risk of osteoporosis in the BMI-based non-general obesity group.

Purposes: To identify the predictors of calcium intake behavior and examine the relationships among bone mineral density, osteoporosis knowledge, osteoporosis health belief, osteoporosis self efficacy and calcium intake behavior of postmenopausal osteoporosis patients. Methods: The subjects consisted of 94 patients. The measurement tools were osteoporosis knowledge test, osteoporosis health belief scale, osteoporosis self-efficacy and calcium intake frequency questionnaire. The data were analyzed using the SPSS WIN 11.0 program. Results: The bone mineral density of the lumbar were $0.75g/cm^2$, T-score -2.67 and the femur neck were $0.67g/cm^2$, T-score -2.30. There was statistically a significant correlation between calcium intake behavior and health motivation (r=0.449, p=0.000) among the osteoporosis health belief. In hierarchial multiple regression analysis, current spouse(12.8%) and health motivation(19.9%) of the osteoporosis health belief explained the 32.7% of variance in calcium intake behavior. Conclusion: Nursing intervention should be developed for increasing the calcium intake behavior through promoting health motivation for the postmenopausal osteoporosis women having no spouse currently.

Objective : To identify the risk factors for postmenopausal osteoporosis in Korea Materials and methods : Bone mineral density (BMD) at the lumbar spine and femoral neck was measured by dual energy X-ray absorptiometry in 808 apparently normal postmenopausal Korean women. Questions about life style, demographic parameters, medical history and social habits etc. were asked on these women; 2ll women with normal bone mineral density, and 597 women with osteopenia or osteoporosis. Results 'Age of >50 years, low body mass index (BMI; <18.5 kg/m2), long duration of menopause(>10 years), and previous history of fracture were associated with increased prevalence of osteopenia or osteoporosis. Women without the outside activity also showed a higher frequency of low bone mass, Risk for osteopenia or osteoporosis was low in women with high BMI (>23 kg/m2) and women with job. The prevalence of low bone mass appeared to be independent of the following parameters: socioeconomic status, familial history, smoking, drinking, exercise, previous use of oral contraceptive, coffee or milk consumption, and degree of sunlight exposure. Conclusion 'Age, BMI, duration of menopause, previous history of fracture and degree of outside activity are the risk factors for postmenopausal osteoporosis in Korea.

Objectives: A community-based, cross-sectional survey was conducted to determine theprevalence of osteoporosis and to evaluate the effects of body composition, health behaviors and reproductive history on bone density in postmenopausal women. Methods: The study subjects were 362 postmenopausal women, aged 45 years old or over, who were invited to the hospital. Information on their socio-demographic characteristics and the potential risk factors such as their past medical history, smoking, alcohol intake, exercise, diet and menstrual/reproductive histories were collected by trained interviewers. Weight, height, the body mass index ($kg/m^{2}$), and body composition variables were measured. Bone mineral density of the lumbar spine was measured by dual energy X-ray absorptiometry (DXA). Results: The prevalence of osteoporosis was 30.6% in the $45{\sim}64$ years old women, 52.5% in the elderly women aged $65{\sim}74$, and 68.7% in the women aged 75 years or over. After adjustment for the effect of potential covariates, those women in the highest 25% (4th quartile) of the lean body mass are less likely to have osteoporosis (aOR=0.31, 95% CI=0.12-0.76), compared with the lowest quartile group. More parity also had significantly detrimental effects on osteoporosis. Conclusions: These findings suggest that the prevalence of osteoporosis in postmenopausal women increased with age from 46.3% of those aged 45-64 to 68.7% for those aged 75 and over. Lean body mass and parity appeared significant contributor to bone mineral density in postmenopausal women in this population.

Objectives: The purpose of this study is to report the clinical effectiveness and safety of herbal medicine treatment for postmenopausal osteoporosis. Methods: Researchers searched papers through 5 online databases including The Cochrane Library Central, Pubmed, China Academic Journal (CAJ), Oriental medicine Advanced Searching Integrated System (OASIS) and Korean studies Information Service System (KISS). Randomized controlled trials (RCTs) that used herbal medicine as treatment were included. Results: Twenty three studies were selected by the selection and exclusion criteria. The treatment group was treated with herbal medicine alone or with herbal medicine and conventional medicine. The control group was treated with conventional medicine. Most common evaluation index was Bone Mineral Density (BMD) followed by total efficacy rate and level of bone metabolism markers, level of sex hormones, etc. Compared with the control group, the treatment group was more effective and safer in all of 23 studies. Conclusions: Herbal treatment alone could be an effective and safe option in treating postmenopausal osteoporosis. Moreover herbal treatment with conventional medicine could improve its therapeutic effect on postmenopausal osteoporosis as well.

Osteoporosis and other related conditions pose a growing public health problem, especially in postmenopausal women. The main purpose of the study was to investigate the correlations among BMD, maternal factors, and life styles, and intake of nutrients in postmenopausal women. One hundred participants in Kyungge-do were divided into three groups according to their BMD measurements measured by DXA. Dietary analysis, anthropometric measurements, and questionares were administered to these women. The percentage of the osteoporosis, osteopenia(Osteopinia), and normal groups were 32%, 48%, and 20% respectively. The average age was significantly the highest in the osteoporosis group. The average age at menopause was 47.2. Osteoporosis group's age at menopause was significantly the lowest. The sleeping hours of the osteoporosis and osteopenia group were significantly longer than the normal group. The intake of vitamin B$_2$was positively correlated with the BMD of femoral neck. The BMD of these two sites was positively correlated with weight, BMI, waist, and hip size and negatively correlated with the length of the menstrual cycle, duration after menopause, the age at the last delivery, and sleeping hours. Spinal BMD positively correlated with hours of outdoor activity. Therefore, maternal factors, lifestyles, and intake of nutrients contribute to BMD.

Purpose: This study was to develop and test a theoretical model based on the revised health belief model explaining osteoporosis prevention behaviors among postmenopausal women under 65. Methods: This secondary data analysis included 342 postmenopausal women under 65 from original data sources of a total of 734 women. The measured instruments were scales for osteoporosis awareness, osteoporosis health belief scale (benefit, barrier, susceptibility, severity, and health motivation), self-efficacy, and osteoporosis prevention behaviors. Data were analyzed using SPSS/WIN 20.0 and AMOS 20.0. Results: The mean age of the subjects was 55.2 years and the mean age of menopause was 51.10. The hypothetical model of osteoporosis prevention behaviors was relatively fit. Osteoporosis prevention behaviors were significantly explained up to 62% by expectation factors (relative benefit, self-efficacy, health motivation) and modifying factors(knowledge only). Expectation factors of health belief had a mediation effect between modifying factors and prevention behaviors. Conclusion: This study partially supported the revised health belief model for explaining osteoporosis prevention behaviors. It provides a basis for developing an educational program focusing on expectation factors and knowledge with the aim of behavioral changes for osteoporosis prevention.

Purpose: The purpose of this study was to investigate the incidence of osteoporosis and falls and their consequences, and to identify predictors of fracture risk in the postmenopausal women. Methods: A total of 687 postmenopausal women were recruited through a stratified convenience sampling. A structured questionnaire was used to obtain osteoporosis and fall history and details of their most recent fall. To predict fracture risk factors, we collected demographic and physical health variables related osteoporosis and fall. Fracture risk was measured by FRAX$^{(R)}$ to calculate 10-year probability of major osteoporotic and hip fracture. Results: The prevalence of osteoporosis was 22.1%, and 66.4% of them had treatments for osteoporosis. The incidence of falls during the past year was 19.2% and 38.6% of those who fell suffered consequent fractures. Women with history of osteoporosis and falls were significant predictors of 10-year probability of major osteoporotic and hip fracture. Other significant predictors were history of fracture, chronic disease, surgical menopause, lower BMI, poorer perceived health and no job. Conclusion: It appears that history of osteoporosis and falls are main predictors of fracture risk. Nursing assessment should be performed by detail history taking for osteoporosis, fall, chronic disease, and fracture to screen fracture risk group among postmenopausal women.

BACKGROUND/OBJECTIVES: The aim of this study was to identify the effect of dairy products, milk and yogurt on osteoporosis incidence among Korean postmenopausal women using prospective cohort data. MATERIALS/METHODS: Between 2001 and 2003, 10,038 participants were recruited in rural and urban areas for a baseline examination of a community-based cohort study. Of those, 1,573 postmenopausal women (aged 40-69 years at baseline) were eligible for the present study. Intakes of dairy products, milk, and yogurt were assessed using a validated semi-quantitative food frequency questionnaire. The speed of sound at the radius and tibia were measured using a quantitative ultrasound device and osteoporosis was defined based on the WHO criteria (T-score ${\leq}-2.5$). RESULTS: During the 4-years follow-up study, the cumulative incidence of osteoporosis was 18.4% (273 cases) in the radius and 33.6% (407 cases) in the tibia. The subjects with higher frequency of dairy product consumption showed a decreased risk of radius osteoporosis after adjusting for potential confounders [hazard ratio (HR) = 0.51, 95% confidence interval (CI): 0.33-0.80 for >1 time/day vs. non consumer; P for trend = 0.0027]. Similarly, high frequency of milk and yogurt consumption had a protective effect on radius osteoporosis risk [milk: HR = 0.60, 95% CI: 0.42-0.87 for > 5-6 times/week vs. non consumer (P for trend = 0.0130), yogurt: HR = 0.51, 95% CI: 0.30-0.85 for > 5-6 times/week vs. non consumer (P for trend = 0.0167)]. However, high dairy products consumption was not related with tibia osteoporosis. CONCLUSIONS: This study suggests that daily intake of dairy products could potentially reduce radius osteoporosis incidence among Korean postmenopausal women.
