Objectives: We wanted to determine the distribution of the clustering of the metabolic risk factors and we wanted to evaluate the related factors in young schoolchildren. Methods: A cross-sectional study of metabolic syndrome was conducted in an elementary school in Seoul, Korea. We evaluated fasting glucose, triglyceride, HDL cholesterol, blood pressures and the body mass index, and we used parent-reported questionnaires to assess the potential risk factors in 261 children (136 boys, 125 girls). We defined the metabolic risk factors as obesity or at risk for obesity ($\geqq$ 85th percentile for age and gender), a systolic or diastolic blood pressure at $\geqq90th$ percentile for age and gender, fasting glucose at $\geqq110mg/dl$, triglyceride at $\geqq110mg/dl$ and HDL cholesterol at $\leqq40mg/dl$. Results: There were 15.7% of the subjects who showed clustering of two or more metabolic risk factors, 2.3% of the subjects who showed clustering for three or more risk factors, and 0.8% of the subjects who showed clustering for four or more risk factors. A multivariate analysis revealed that a father smoking more than 20 cigarettes per day, a mother with a body mass index of = $25kg/m^2$, and the child eating precooked or frozen food more than once per day were associated with clustering of two or more components, with the odds ratios of 3.61 (95% CI=1.24-10.48), 5.50 (95% CI=1.39-21.73) and 8.04 (95% CI=1.67-38.81), respectively. Conclusions: This study shows that clustering of the metabolic risk factors is present in young schoolchildren in Korea, with the clustering being associated with parental smoking and obesity as well as the child's eating behavior. These results suggest that evaluation of metabolic risk factors and intervention for lifestyle factors may be needed in both young Korean children and their parents.

The study investigated the relationship between vitamin D status and lifestyle risk factors in office workers. A total of 515 office workers(336 men and 179 women) aged 30 years or older were voluntarily recruited from S-city. Along with serum vitamin D levels, lifestyle risk factors including obesity index, physical fitness, metabolic risk factors, lipids profile and sedentary behavior were measured using standardized protocols. Subjects were classified as deficiency (<20ng/mL), insufficiency (20-29ng/mL), and sufficiency (≥30ng/mL) based on serum vitamin D levels. Linear contrast analysis using one-way ANOVA showed significant linear decreases in mean body fat (p=.030) and sedentary behavior (p<.001) and significant linear increases in skeletal muscle (p=.037), cardiorespiratory fitness (p<.001) and HDL-C (p=.013) across incremental serum vitamin D levels. Compared with the low cardiorespiratory fitness group, the high cardiorespiratory fitness group had a significantly higher odds ratio (men OR=2.144, p=.042, women OR=1.971, p=.045) for having vitamin D insufficiency or deficiency even adjustment after age. Compared to the shortest sitting time group, the longest sitting time group had a significantly higher odds-ratio in a group of female office workers (OR=1.262, p=.043) for having vitamin D insufficiency or deficiency even adjustment after age. The current findings of the study showed that poor physical fitness and sedentary behavior were the risk factors of low serum vitamin D levels, implying the urgent need for a healthy lifestyle modification along with vitamin D supplementation.

Benign prostatic hyperplasia (BPH) is one the most common prostate diseases in middle aged and elderly men. This study was conducted to investigate diet and lifestyle risk factors for benign prostatic hyperplasia in a community-dwelling free-living population group. The dietary data were collected from the 601 male subjects aged 50-79 years using the 24-hour recall method. The mean age of the BPH group ($63.0{\pm}7.9$ years) was significantly higher than that of the non-BPH ($58.8{\pm}7.4$ years). Among many nutrients, the amount of animal fat intake was increased while that of carbohydrate intake decreased in subjects with BPH compared to those with non-BPH. In BPH subjects, the proportion of energy from fat was also greater than in subjects with non-BPH. The logistic regression analysis on the food consumption data showed that the consumption of total animal food was increased while that of mushrooms was decreased in patients with BPH compared to the subjects with non-BPH. The age-adjusted odds ratios and 95% confidences limits for BPH incidence in subjects whose milk and milk products, beverages and alcoholic liquors intake was greater than the median were 1.796 (1.167-2.782) and 1.738 (1.129-2.676) respectively, compared to those in subjects whose intakes were below the median. These results may be applicable in the development of a nutrition intervention and education program toward a reduction in the risk for benign prostatic hyperplasia.

Objectives : High-normal blood pressure' is a factor influencing decision to initiate targeted intensive intervention strategy in westernized populations. JNC-VI offered the vigorous lifestyle modification for persons with 'high-normal blood pressure', who could be early detected. As a hypertension seems to be the result of multiple genetic factors operating in concert with associated environmental factors, it will be necessary to identify the high-normal blood pressure as a risk factor of hypertension for applying primary prevention strategy in Korean people. Methods : Although cohort study design might be adequate to recruit incidence cases, to keep time sequence of events, and to prevent information bias, nested case-control study was chosen for avoiding measurement errors because hypertension is a benign disease. Source population was the 'Seoul Cohort' participants and follow-up was done by using Korea Medical Insurance Corporation's database on the utilization of health services from 1 Jan93 to 30Jun97. Incidence cases were ascertained through the chart review, telephone contacts, and direct blood pressure measurements. Controls included the pairing of 4 individuals to each case on the basis of age. Results : As 75% of 247 incident cases had high-normal blood pressure, the crude odds ratio for hypertension was 2.04 (95% CI 1.47-2.83). Another statistically significant risk factors of hypertension were body mass index, dietary fiber, alcohol consumption, weekly activity and history of quitting smoking. The multivariate odds ratio of high-normal blood pressure adjusted for all risk factors was 1.84 (95% CI 1.31-2.56). Among high-normal blood pressure group, body mass index, weekly ethanol amounts, weekly physical activity, and dietary fiber except history of quitting smoking were still risk factors of hypertension. Conclusion : 'High-normal blood pressure' is a risk factor for hypertension in Korean middle-aged men, which represents that the vigorous lifestyle modification for persons with 'high-normal blood pressure' is need.

The purpose of this study was to identify population subgroups with similar patterns of diet quality, physical activity, alcohol consumption and cigarette smoking of Korean. The cluster analysis was conducted using the data from Korea National Health Survey(KNHS) in 1995, which consisted of 5,805 persons. We identified six health behavior typologies : 32.9% of the sample had a good diet but sedentary activity level(good diet lifestyle), 7.2% had high activity level but less diet quality(fitness lifestyle). Individuals in the passive lifestyle cluster(39.1%) had no active health promoting activities but tended to avoid risk taking health behavior such as cigarette smoking and alcohol drinking. 1.1% of the sample were in a drinking cluster, 17.2% in a smoking cluster and 2.5% had a hedonic lifestyle characterized by heavy drinking and smoking. The other characteristics of these lifestyle clusters could be presented by demographic and socioeconomic factors.

Background: The influence of lifestyle diseases on postoperative complications and long-term survival in patients with non-small cell lung cancer (NSCLC) is unclear. The aim of this study was to determine whether lifestyle diseases were significant risk factors of perioperative and long-term surgical outcomes in elderly patients with stage I NSCLC. Methods: Between December 1995 and November 2013, 110 patients aged 65 years or older who underwent surgical resection of stage I NSCLC at Dong-A University Hospital were retrospectively studied. We assessed the presence of the following lifestyle diseases as risk factors for postoperative complications and long-term mortality: diabetes, hypertension, chronic obstructive pulmonary disease, stroke, and ischemic heart disease. Results: The mean age of the patients was 71 years (range, 65 to 82 years). Forty-six patients (41.8%) had hypertension, making it the most common lifestyle disease, followed by diabetes (n=23, 20.9%). The in-hospital mortality rate was 0.9% (n=1). The 3-year and 5-year survival rates were 78% and 64%, respectively. Postoperative complications developed in 32 patients (29.1%), including 7 (6.4%) with prolonged air leakage, 6 (5.5%) with atrial fibrillation, 5 (4.5%) with delirium and atelectasis, and 3 (2.7%) with acute kidney injury and pneumonia. Univariate and multivariate analyses showed that the presence of a lifestyle disease was the only independent risk factor for postoperative complications. In survival analysis, univariate analysis showed that age, smoking, body mass index, extent of resection, and pathologic stage were associated with impaired survival. Multivariate analysis revealed that resection type (hazard ratio [HR], 2.20; 95% confidence interval [CI], 1.08 to 4.49; p=0.030) and pathologic stage (HR, 1.89; 95% CI, 1.02 to 3.49; p=0.043) had independent adverse impacts on survival. Conclusion: This study demonstrated that the presence of a lifestyle disease was a significant prognostic factor for postoperative complications, but not of survival, in elderly patients with stage I NSCLC. Therefore, postoperative complications may be influenced by the presence of a lifestyle disease.

Breast cancer is the most commonly diagnosed invasive cancer among women. Many factors, both genetic and non-genetic, determine a woman's risk of developing breast cancer and several breast cancer risk prediction models have been proposed. It is vitally important to risk stratify patients as there are now effective preventive strategies available. All women need to be counseled regarding healthy lifestyle recommendations to decrease breast cancer risk. As such, management of these women requires healthcare professionals to be familiar with additional risk factors so that timely recommendations can be made on surveillance/risk-reducing strategies. Breast cancer risk reduction strategies can be better understood by encouraging the women at risk to participate in clinical trials to test new strategies for decreasing the risk. This article reviews the advances in the identification of women at high risk of developing breast cancer and also reviews the strategies available for breast cancer prevention.

Purpose: This study was undertaken to identify stroke risk with risk factors and knowledge of stork in women with prehypertension. Methods: A total of 46 pre-hypertensive women in urban area aged 44.8 (SD 11.4) yr old in average were selected by a convenient sampling. Demographic data, risk factors, and knowledge of stroke were assessed through face to face interview. Stroke risk scores were calculated based on points given to age, systolic blood pressure, smoking, DM, and heart disease in Framingham stroke risk score. Data were analyzed by SPSS WIN 12.0 using descriptive statistics, two sample t-test, and Pearson's correlation coefficient. Results: The mean systolic blood pressure of participants was 133.11 mmHg, and HDL cholesterol was lower than the recommended level, although rest of physiologic risk factors were within normal. Of the participants, 82% did not do regular physical activity and 75% did not control fat intake persistently. Mean stroke risk points and knowledge scores were 4.48 and 29.15, respectively, which were significantly different between women with and without persistent controlling fat intake. Conclusion: Results indicate stroke prevention intervention for prehypertensive women should address comprehensively modifying lifestyle as well as physiologic factors, and information focusing on stroke risk factors and warning symptoms.

This study was conducted to identify the influence of the convergent lifestyles of the elderly consisting of physical exercise, smoking, drinking and social participation and the types of social participation on the risk of cognitive decline by using the 6th Korean Longitudinal Study of Ageing(KLoSA). Total 4,298 people aged 65 or older were included. Results show that all of lifestyle factors are significantly effected to prevent cognitive decline, social participation was derived as the most important explanatory variable to lower the risk of cognitive decline. In addition, participating in the religious groups, ascriptive groups, and expressive groups lowered the risk of cognitive decline. Therefore, active support at the community and policy for improving the convergent lifestyle of the elderly are needed.

Objectives: Being overweight or obese is central to metabolic syndrome, and these characteristics constitute dominant risk factors for chronic diseases. Although behavioral factors, including eating habits and sedentary lifestyles, are considered to be determinants of obesity, the specific childhood factors that contribute to this condition have not been clearly defined. Methods: The subjects consisted of 261 children aged 7- 9 years who were recruited from an elementary school during October 2003. Information was obtained from their parents using a questionnaire focused on eating behaviors and lifestyle factors, additional data were also collected via anthropometric measurements and biochemical examinations, including blood tests. Results: A total of 48 (18.4%) of the 261 children were overweight, and 34 (70.8%) had at least one other component of metabolic syndrome. Eating behaviors emerged as significant lifestyle-related risk factors for being overweight or obese. Those who engaged in overeating more than twice per week had three times the risk of being overweight (odds ratio [OR], 3.10, 95% confidence interval [CI], 1.39 to 6.92), and those who ate rapidly had three times the risk of being overweight (OR, 3.28; 95% CI, 1.68 to 6.41). Those who had fewer family meals (fewer than 2?3/month) had a nine times higher risk of being overweight than those who had family meals more frequently (at least 1/day) (OR, 9.51; 95% CI, 1.21 to 74.82). Conclusions: This study showed that being overweight or obese during preadolescence is associated with a higher risk of metabolic syndrome and is related to unhealthy eating behaviors. Thus, weight-control strategies and healthy eating behaviors should be developed early in life to reduce the risk for metabolic syndrome.
