We have examined the hypothesis that the Gly972Arg variant of the insulin receptor substrate 1 (IRS1) gene is associated with the components contributing to overweight (obesity) and metabolic syndrome. We describe IRS1 genotype frequencies in 274 Korean men. The frequencies of Gly972Gly (GIG) and Gly972Arg (G/A variant) of the IRS1 gene were 88.3% and 11.7%, respectively, and the differences in frequencies between the overweight (BMI$\geq$25kg/m$^2$) group and non-overweight (BMI<25kg/m$^2$) group were statistically significant. The subjects with G/A variant of IRS1 gene in non-overweight had significantly higher level of visceral fat thickness and adiponectin/leptin ratio than those with GIG alleles. In overweight group, the subjects with G/A variant of IRS1 gene also showed significantly higher level of insulin than those with GIG alleles. These results suggest that the IRS1 genetic polymorphism is involved in the occurrence of overweight, as well as metabolic syndrome.

Objectives: This study was conducted to investigate the correlation between the health-related quality of life assessment according to socio-demographic characteristics, health behavior, and BMI for Gyeonggi-do community population. Methods: The 2012 Community Health Survey data was used. The data were collected by using a cross-sectional study with face-to-face interview. The variables of smoking, AUDIT, exercise, BMI, and Euroqol EQ-5D instrument were selected for analyses. The Difference on the EQ-5D index among groups were tested with Mann-Whitney U test and Kruskal Wallis test. Results: The EQ-5D index for Gyeonggi-do community was 0.951(${\pm}0.104$). The index were significantly different by sex, age, marital status, education level, and occupation. The health-related quality of life showed lower EQ-5D index in women than men, older than young, and less educated. The index were significantly different by health behavior (smoking, drinking, moderate physical activity and exercise) for both men and women). For BMIs, the index was lower to under-weighted male and over-weighted female. Conclusions: The findings suggest that the future intervention of health promotion programs should be carefully designed and tailored by health behavior and obese groups.

BACKGROUND/OBJECTIVES: A number of studies examined secular trends in blood lipid profiles using time series data of national surveys whereas few studies investigated individual-level factors contributing to such trends. The present study aimed to examine secular trends in dietary and modifiable factors and hyper-LDL-cholesterolemia (HC) prevalence and evaluate their associations using time series data of nationwide surveys. SUBJECTS/METHODS: The study included 41,073 Korean adults aged ≥ 30 years from the 2005, 2007-2009, 2010-2012, 2013-2015, and 2016 Korea National Health and Nutrition Examination Surveys. Stepwise logistic regression analysis was performed to select significant factors associated with HC, which was defined as serum LDL cholesterol levels ≥130 mg/dL. RESULTS: The following factors showed a positive association with HC (P < 0.05): for men having higher body mass index (BMI), being married, having an office job, and consuming higher dairy and vegetable oil products; for women having higher age or BMI, having no job or a non-office job, not in a low-income household, and consuming higher dairy products. In the given model, the 2016 survey data showed that a 2 kg/㎡ reduction in BMI of obese persons resulted in a decreased HC prevalence from 30.8% to 29.3% among men and from 33.6% to 32.5% among women. CONCLUSIONS: Based on these findings, it is suggested that primary prevention programs should advocate having proper BMI for Korean adults with a high-risk of HC. However, whether discouraging consumption of dairy and vegetable oil products can reduce HC prevalence warrants further studies with a prospective longitudinal design.

There are a few studies that reported the association of sleep duration with calorie intake and energy expenditure. Using cross-sectional data from a population-based prospective study, we evaluated the association of sleep duration with indicators of obesity including body mass index and waist circumference, calorie intake and its proportion of macronutrients, and physical activity. The study subjects were 4,226 male and female adults, who were aged 40 to 69 years and were free of diagnosed cardiovascular disease, diabetes mellitus, and dyslipidemia at baseline. Robust regression analysis was used to analyze associations. The study found that sleep duration is inversely associated with waist circumference, calorie intake, and percent of calories from fat intake and is positively associated with percent of calories from carbohydrate intake and physical activity. The inverse association between sleep duration and waist circumference was stronger among men than among women. The inverse association between sleep duration and calorie intake was stronger among women than among men and such association was also stronger among obese persons than those with a normal body mass index. The positive association between sleep duration and physical activity was strongly demonstrated regardless of sex or obesity. Physical activity is positively associated with sleep duration independent of potential confounding factors including age, sex, income, occupation, marital status, education, smoking status, waist circumference, calorie and macronutrient intake, and alcohol intake.

The purpose of this study were to explain the difference in body dimensions and body shape between the early in the twenties and the late in the twenties and to get information clothing construction. Subject were 483 Korean males, which were extracted from men's physique investigation on June to August in 1989, consisted of 149 aged $19\~24$ and $25\~29$. T-test and factor analysis were applied to 52 measurement items and 58 indices. The Result of the study were as follow; 1. As regards $19\~24$ aged group, they were taller their waistband level was higher than the late in the twenties. Upper arm and thigh were thick in comparison with trunk. As the difference between shoulder and waist in dimension was great, they showed reverse triangular silhouette. As regard $25\~29$ aged group, their body from variation between individual was greater than that of 19~24 aged group and they were obese on mainly waist and abdominal parts. For that reason, waist band level became low and their shoulder and hip looked slim relatively that reason, waist band level became low and their shoulder and hip look slim relatively to bust and waist parts. 2. Between $19\~24$ aged and $25\~29$ aged groups, as each had charicteristic body from, there was the difference in factor structure. 3. The change of men's body from with age in their twenties was obeseness on the whole body but the increasing rate of upper arm and thigh girth was less than that of trunk girth.

Purpose: The purpose of this study was to identify the features, risk scores and risk factors for deep vein thrombosis in critically ill patients who developed deep vein thrombosis in their lower extremities. Methods: The participants in this prospective descriptive study were 175 adult patients who did not receive any prophylactic medication or mechanical therapy during their admission in the intensive care unit. Results: The mean age was 62.24 (${\pm}17.28$) years. Men made up 54.9% of the participating patients. There were significant differences in age, body mass index, and leg swelling between patients who developed deep vein thrombosis and those who did not have deep vein thrombosis. The mean risk score was 6.71(${\pm}2.94$) and they had on average 4.01(${\pm}1.35$) risk factors. In the multiple logistic regression, body mass index (odds ratio=1.14) and leg swelling (odds ratio=6.05) were significant predictors of deep vein thrombosis. Conclusion: Most critically ill patients are in the potentially high risk group for deep vein thrombosis. However, patients who are elderly, obese or have leg edema should be closely assessed and more than one type of active prophylactic intervention should be provided.

Purpose: The purpose of this study was to provide basic data to develop a Fall Prevention Education Program by comparing and analyzing fall experiences and the factors that influence elderly people with dementia suffering falls. Methods: The participants were 302 patients with dementia aged 60 years or older with nursing records of hospitalization in three nursing homes located in a metropolitan area. The SPSS/Win 21.0 package was used to analyze the collected data. A logistic regression analysis was performed to identify the influence factors related to fall experiences. Results: For men, fall experiences were more frequent given the following factors: overweight; high fall risk tendency; aged 90 and above; married; dementia duration period of 5 to 9 years; and taking medication for dementia. For women, the factors included age range of 80 to 89; overweight; obese; both low and high fall risk tendency; separation by death; and having spent less than 1 year in nursing homes. Conclusion: We anticipate positive results in fall prevention education programs for the elderly with dementia if the results of this study are used as basic data, and interventions are customized to consider the sex and the relevant influence factors as to fall experiences.

Background: In order to determine the role of meat consumption and related nutrients in the etiology of prostate cancer we conducted a case-control study among Uruguayan men in the time period 1998-2007. Results: The study included 464 cases and 472 controls, frequency matched for age and residence. Both series were drawn from the four major public hospitals in Montevideo. Unconditional logistic regression was used to estimate odds ratios (ORs) and 95 % confidence intervals (95 % CI) of prostate cancer by quartiles of meat intake and related nutrients. The highest vs. the lowest quartile of intake of total meat (OR = 5.19, 95 % CI 3.46-7.81), red meat (OR = 4.64, 95 % CI 3.10-6.95), and processed meat (OR = 1.78, 95% CI 1.22-2.59) were associated with increased risk of prostate cancer. Meat nutrients were directly associated with the risk of prostate cancer (OR for cholesterol 5.61, 95 % CI 3.75-8.50). Moreover, both total meat and red meat displayed higher risks among obese patients. Conclusions: This study suggests that total and red meat and meat nutrients may play a role in the etiology of prostate cancer in Uruguay.

Objectives : This study was performed to assess the effect onf abdominal obesity treatment on changes in abdominal subcutaneous and visceral fat. Methods : The study was conducted on 61 abdominally obese patients (13 men and 48 women). Measures of body weight, waist circumference, abdominal subcutaneous and visceral fat area by CT scan, and V/S ratio (Viscero-subcutaneous fat ratio) were acquired before and after Kirindiet therapy. Paired t-test and Wilcoxon signed rank tests were used to est the effects of teatment. Results : Following a mean of 68 days of treatment, waist circumference (-15%), abdominal total fat (-40%), subcutaneous fat (-37.9%), visceral fat (-47.8%) and V/S ratio (-11.1%) were significantly reduced (p<0.05). The change in V/S ratio in female patients was not statistically significant (p=0.491) whereas the change in the V/S ratio in male patients was significant indicating a greater loss of visceral fat (p=0.017). Please check that my changes reflect what the study found Conclusions : The reduction in visceral fat was greater than for subcutaneous fat in male patients but not for female patients.
