Purpose: The purpose of this study was to identify the influencing factors on osteopenia and osteoporosis in Korean aged 50 years and above. Methods: Data from the Fifth Korean National Health and Nutrition Examination Survey (KNHANES V-1, 2010) were obtained and 2,773 subjects who got bone density test and were classified "normal, osteopenia or osteoporosis" were selected. Data were analyzed $x^2$ test, ANOVA, $Scheff{\acute{e}}$ test and logistic regression using the SAS 9.4. Results: Gender, age, days of flexibility exercise, vitamin D in blood and weight were found to be influencing factors for osteoporosis in Korean aged 50 years and above. Gender. age and smoking were found to be influencing factors for osteopenia in Korean aged 50 years and above. Conclusion: This study suggested that nursing intervention should include exercise promotion, intake vitamin D, smoking cessation and weight control program in order to reduce the prevalence of osteoporosis and osteopenia.

Purpose: The purpose of the study is to identify differences in BMI between early and late elderly people, and factors having influence of them. Methods: This study is an analysis of secondary data that used the raw materials from the KNHANES from 2008 to 2010. The subjects involved in the final analysis were 4,772 elders aged 65 or higher. Descriptive statistics, $x^2$-test and F-test, and CSGLM from the complex sample design were used for the data analysis with SPSS/WIN 19.0. Results: Significant differences were observed in the socio-demographic characteristics, health behaviors and diet habits between early and late elderly people. Adjusted for gender, location of residence, and living alone, the factors that affected BMI of the early elderly people included current smoking status, number of disease, difficulty in chewing, and number of meals per day while those that affected BMI of the late elderly people were current smoking status, number of disease, self-rated health, and difficulty in chewing. Conclusion: The study concludes that we should consider age-specific traits for monitoring the weight status of the elderly and providing appropriate weight management programs for the elderly.

Objectives: Despite the considerable interest in the increase in obesity particularly of socially disadvantaged group in Korea, how obesity varies according to various socio-demographic characteristics still remains largely unanswered. To further develop the understanding of obesity in Korea, the present study focuses on the possibility that the relationship between educational attainment and obesity varies across age. Methods: Using 2010 Korea National Health & Nutrition Examination Survey (KNHANES), this study divides the adults into male and female groups and examines the interaction effect of age and educational attainment on obesity through binominal logit models for each group. Results: The most educated male group is more likely to be obese than those who did not complete high school. And the relationship between male's educational attainment and obesity does not significantly change across age. In contrast to male's obesity pattern, female educational attainment has a significant negative association with obesity. The gap in obesity across educational groups converges after middle ages in female. Conclusions: Health policies should pay more attention to those who are more vulnerable to obesity risk in order to effectively reduce obesity.

Purpose: The purpose of this study was to investigate effects of obesity on self-rated health in Korean males and females. Methods: The 2010 Korean National Health and Nutrition Examination Survey (KNHANES V-1) data were used. Participants included 1,231 males and 1,289 females aged 20 years or older and had no disease. Chi-square test, t-test, and multiple logistic regression with dummy variables using SAS 9.2 were performed. Results: From univariate analysis, total body fat was significantly greater in males with a self-perception of poor health (p=.006), and the percentage of total body fat was significantly greater in males and females with a self-perception of poor health (p for all=.001). After controlling for demographic and health behavior variables, similar results were found. Females with higher education had a healthy perception of their health. Smoking for males and drinking for females were significantly related to unhealthy perception of their health. Conclusion: The current study provides evidence that obese Korean males and females had worse self-rated health, even though they had no disease. In particular, it is important to note that the relatively direct obesity measures from Dual Energy X-Ray Absorptiometry, such as total body fat and percentage of body fat, were significantly related to self-rated health.

Objectives: We investigated the clustering of selected lifestyle factors (cigarette smoking, heavy alcohol consumption, lack of physical exercise) and identified the population characteristics associated with increasing lifestyle risks. Methods: Data on lifestyle risk factors, sociodemographic characteristics, and history of chronic diseases were obtained from 7,694 individuals ${\geq}20$ years of age who participated in the 2005 Korea National Health and Nutrition Examination Survey (KNHANES). Clustering of lifestyle risks involved the observed prevalence of multiple risks and those expected from marginal exposure prevalence of the three selected risk factors. Prevalence odds ratio was adopted as a measurement of clustering. Multiple correspondence analysis, Kendall tau correlation, Man-Whitney analysis, and ordinal logistic regression analysis were conducted to identify variables increasing lifestyle risks. Results: In both men and women, increased lifestyle risks were associated with clustering of: (1) cigarette smoking and excessive alcohol consumption, and (2) smoking, excessive alcohol consumption, and lack of physical exercise. Patterns of clustering for physical exercise were different from those for cigarette smoking and alcohol consumption. The increased unhealthy clustering was found among men 20-64 years of age with mild or moderate stress, and among women 35-49 years of age who were never-married, with mild stress, and increased body mass index (>$30\;kg/m^2$). Conclusions: Addressing a lack of physical exercise considering individual characteristics including gender, age, employment activity, and stress levels should be a focus of health promotion efforts.

BACKGROUND/OBJECTIVES: The objective of the study was to provide useful insights into plain water intake of Korean adults according to life style, anthropometric, and dietary characteristics. SUBJECTS/METHODS: The data from the 2008-2010 Korea National Health and Nutrition Examination Survey were used. The subjects were 14,428 aged 20-64 years. Water intake was estimated by asking the question "How much water do you usually consume per day?". Dietary intake was estimated by 24-hour dietary recall. A qualitative food frequency questionnaire including 63 food items was also administered. RESULTS: The mean plain water intake for men and women were 6.3 cup/day and 4.6 cup/day, respectively. Plain water intake increased as lean body mass, waist circumference, and body mass index levels increased, except for percentage of body fat. As energy and alcohol intakes increased, plain water intake increased. As total weight of food intake and total volume of food intake increased, plain water intake increased. Plain water intake increased as consumption of vegetables increased. Plain water intake increased as frequencies of green tea, alcoholic drink, and all beverages were increased in men. Plain water intake increased with increased frequencies of green tea, milk, soy milk, and alcoholic drink and decreased frequencies of coffee and soda in women. CONCLUSIONS: Our results suggest that persons who had a higher waist circumference or lean body mass and women with higher BMI consumed more plain water. The persons eating high quality diet, or the persons who had more vegetables, green tea, milk, soy milk, or alcoholic drink consumed more plain water.

Purpose: Obesity has been associated with higher total blood mercury levels, based on animal studies; however, studies that focus on children and adolescents are lacking. We aimed to assess the association between total blood mercury levels and the incidence of overweight and abdominal obesity in Korean adolescents. Methods: The study population comprised 1,567 adolescents (793 boys and 774 girls; aged 10-19 years), who participated in the Korea National Health and Nutrition Examination Survey 2010-2013. We analyzed total blood mercury levels according to obesity status in all participants. Results: The geometric mean of total blood mercury levels was $1.93{\mu}g/L$. Participants with overweight ($2.20{\mu}g/L$) and obesity ($2.17{\mu}g/L$) had higher levels than those with normal weight ($1.86{\mu}g/L$, P<0.0001). The prevalence of overweight significantly increased with elevation of the total blood mercury quartile in both sexes. Increased incidence of abdominal obesity corresponding to increased total blood mercury level was observed in boys. After adjusting for covariates, those in the highest total blood mercury quartile were found to be at higher risk of overweight/obesity than those in the lowest quartile in both sexes (odds ratio [95% confidence interval]: boys, 3.27 [1.66-6.41]; girls, 1.90 [1.03-3.49]). The association between total blood mercury quartile and abdominal obesity was significant after controlling for covariates in boys (2.35 [1.05-5.24]). Conclusion: Our results suggest an association between total blood mercury levels and overweight in Korean adolescents.

This study examined the age-related bone mineral density (BMD), accumulated bone loss rate (ABLR) at different skeletal sites in Korean men using the data from the Korea National Health and Nutrition Examination Survey (KNHANES)(the 1st (2010), 2nd (2010) and the year at the 5th survey). The cubic regression model was found to be the best for describing the age-related changes in BMD. The lumbar spine, total hip, femoral neck, trochanter, Ward's triangle in the bone mineral density difference were analyzed by ANOVA. The peak BMD was at 20-24 years at the lumbar spine, total hip, femoral neck, trochanter, Ward's triangle, and the 75-79 years of age group had the highest Accumulated Bone Loss Rate. Therefore, intensive management will be necessary for men over 75 years, and a diagnosis of osteoporosis in Korean men should be made according to The International Society for Clinical Densitometry; ISCD.

Recent studies suggest that vitamin D deficiency and cardiometabolic disorders are becoming increasingly more prevalent across multiple populations. However, there is a lack of comprehensive data for Korean adults. We investigated the vitamin D status, the prevalence of vitamin D deficiency and its association with metabolic syndrome (MS) risk in Korean adults aged 20 years or older. The study subjects (n = 18,305) were individuals who participated in the Korean National Health Examination and Nutrition Survey (KNHANES) in 2008-2010. Vitamin D status (25-hydroxyvitamin D [25(OH)D]) was categorized as < 20, 21-29, and ${\geq}$ 30 ng/mL, which are the cut-off points for deficiency, insufficiency and normal limits. A wide variety of cardiometabolic risk factors were compared according to the vitamin D status. Vitamin D deficiency was found in 53.9% of men and 70.5% of women. Mean BMI, systolic BP, HbA1c and low density lipoprotein cholesterol (LDL-C) were highest in the vitamin D deficiency group in both genders. Further, the MS was most prevalent in the vitamin D deficiency group in both genders (12.3%, P = 0.002 in men and 9.2%, P < 0.001 in women). Compared to the vitamin D normal group, the adjusted odds ratio (ORs) (95% confidence interval [95% CI]) for MS in the vitamin D deficiency group were 1.46 (1.05-2.02) in men and 1.60 (1.21-2.11) in women, after adjusting for confounding variables. In conclusion, Vitamin D deficiency is a very common health problem in Korean adults and is independently associated with the increasing risk of MS.

This study identifies the factors influencing Quality of Life (QoL) in both male and female workers with diabetes mellitus and examines the differences between them. Using data from the Korea National Health and Nutrition Examination Survey (KNHANES) for 2010-2017, 1693 workers (1082 males; 611 females), aged 19 or over, with diabetes mellitus were enrolled in the study. Data were analyzed by complex sample linear regression using SPSS/WIN 23.0. The factors influencing QoL differed between males and females. The common factors included household income, education, job, stress, disease duration, and disease complications. The additional factors in males included working style, and, in females included age, marital status, drinking habits, and the treatment and control of the disease. Males had a higher QoL than females in all the sub-factors. Patients with diabetes mellitus require gender-specific intervention and governmental and social policies that can support it must be developed.
