BACKGROUND/OBJECTIVES: Numerous studies have examined the relationship between drinking behaviors and metabolic syndrome (MetS) for adults, but these include very few studies for young adults. This study therefore undertook to investigate the association between drinking behaviors and components of MetS among adult drinkers aged 20-30 years. SUBJECTS/METHODS: Using the 2016-2018 Korea National Health and Nutrition Examination Survey data, drinking behaviors of adults in the age group 20-30 years were divided into 4 groups: 1) group A, good drinking habits; 2) group B, frequent binge drinking but not frequent drinking; 3) group C, frequent drinking but not frequent binge drinking; 4) group D, frequent drinking and binge drinking. The association between MetS components and drinking behaviors was analyzed by applying multiple logistic regression analysis. RESULTS: We determined the prevalence risk compared to group A. In men, the prevalence risk of high triglyceride (TG) increased 2.051-fold in group C and 1.965-fold in group D. Moreover, in group D, the prevalence risk of low high density lipoprotein cholesterol (HDL-C) increased 0.668-fold, high blood pressure (BP) increased 2.147-fold, and MetS increased 1.567-fold. In women, there was an increased prevalence risk of low HDL-C (0.353-fold) and MetS (3.438-fold) in group C, whereas group D showed increased prevalence risk of abdominal obesity (2.959-fold), high TG (1.824-fold, and low HDL-C (0.424-fold). CONCLUSIONS: Our study indicates that frequent drinking increases the risk of high TG, whereas frequent and binge drinking increases the risk of high TG, low HDL-C, high BP, and prevalence of MetS in men. In women, frequent drinking without binge drinking increases the risk of low HDL-C and MetS, whereas frequent and binge drinking increases the risk of abdominal obesity, high TG, and low HDL-C. We propose that improvements in the drinking behaviors can reduce the prevalence of MetS.

Chronic obstructive pulmonary disease (COPD) had been considered the only major disease that is continuing to increase in prevalence. There were a few studies about the change of the prevalence of COPD, which showed the prevalence of COPD did not increase. In this review, we report on the trends in the prevalence of COPD in Korea using the data from Korea National Health and Nutrition Examination Survey (KNHANES). The prevalence of COPD in 2015 was 13.4% (male, 21.6%; female, 5.8%). The prevalence of COPD did not change much, which ranged from 13.1% to 14.6% during the period from 2010 to 2015. Among the subjects found to have COPD by spirometry, only 2.8% had been diagnosed as COPD by physicians during the period from 2011 and 2015. In conclusion, the prevalence of COPD did not change significantly during the period from 2010 to 2015. And most COPD patients still had not been diagnosed by physicians and consequently had not been treated appropriately.

Purpose: The purpose of this study is to estimate the prevalence of the metabolic syndrome in pre-menopausal housewives and to explore controllable and uncontrollable factors regarding metabolic syndrome. Methods: The study population of this cross-sectional survey was from the Korean Health and Nutrition Examination Survey (KHANES) 2010 through 2015, including the fifth and sixth population-based studies. The criteria for metabolic syndrome include waist circumference, blood pressure, fasting plasma glucose, triglyceride, high-density lipoprotein (HDL) based on Korean Clinical Practice Guideline for Metabolic Syndrome by the Korean Academy of Family Medicine 2015. Results: Among the 2,498 subjects, 247 subjects had metabolic syndrome and the prevalence was estimated to be 9.9%. The number of subjects who met the criterion of HDL was 936 (36.2%), which was the most prevalent among the criteria for metabolic syndrome. Statistically significant (p<.05) factors include age, livinghood benefit group, perceived health status, obesity, family history of DM, sleeping time, awareness of stress,leukocyte, and erythrocyte count. The odds ratio of obesity in the BMI ${\geq}25$ group was 12.59 times as high as that of the BMI <25 group (p<.001) for metabolic syndrome. Conclusion: The prevalence of metabolic syndrome in pre-menopausal housewives in the survey was not low, and it is necessary to develop and apply comprehensive health habit management programs to improve controllable factors including exercise and food intake.

Objectives : To estimate the prevalence of hypertension, rates of awareness, treatment modalities, and control of hypertension, and also to identify factors in rural Korea that are related to these aspects of hypertension. Methods : A cross-sectional survey, including blood pressure(BP) measurements and interviews, investigating the variables in the health belief model was peformed from August to November, 1999 on 1,426 (79.4%) study subjects out of 1,797 registered residents over 30 years old in Ibansong-Myun, Chinju City. A second survey was peformed from January to March, 2000 on 376 (80.0%) subjects out of 470 hypertensive (or suspected hypertensive) subjects found in the first survey. Two BP readings were taken in each survey using a standard mercury sphygmomanometer. Hypertension was defined as either a BP reading $\geq$ 140/90 mmHg in both surveys, or as subjects on oral hypertensive medication. Results : Estimated hypertension prevalence was 24.9% for men, and 30.4% for women. Rates of hypertension awareness, treatment (the regular use of oral hypertensives), and control (reduction of BP to <140/90 mmHg) were 52.5%, 34.4%, and 12.9%, respectively. The factors related to lower hypertension awareness in the logistic regression analysis were male gender, farming occupation, and higher perceived barrier to medical treatment (those for whom visiting health professionals is a burden). Conclusions : To improve the low awareness, treatment, and control of hypertension, a more active and out-reaching hypertension control program, including routine BP measurements for every visitor to primary care facilities, is needed in rural Korea.

This study was designed to estimate the prevalence of arthritis and to identify subgroups with high prevalence rates of arthritis. Study subjects were 18,406 Korean adults aged 19 and more from the 4th (2007-2009) Korea National Health and Nutrition Examination Surveys data. Annual self-reported prevalence and its rate ratios by demographic and behavioral factors were calculated using SAS 9.2 with survey procedure. The result was as follows. The crude prevalence of arthritis was 11.7% (osteoarthritis 10.2% and rheumatoid arthritis 1.7%). The prevalence was increased by age strata (2.4% in 19-44 aged, 16.4% in 45-64, 38.3% in 65 and more). After adjusting for age, we found the subgroups with high prevalence: older people, women, residents in non-apartment area, separated and divorced people, people with low education, people with several occupations (agricultural and fishery workers, elementary occupations, and unemployed), people with low household incomes, people with medical aid, and people with higher BMI. Those subgroups may be target populations in community health programs to control the disability from arthritis.

Background: Dokha is a novel form of smoking in United Arab Emirates (UAE) on which there is very little published literature, especially among adolescents, and this form of smoking has been not been addressed adequately in the smoking cessation strategies in the UAE. Objectives: To assess the prevalence of dokha smoking among male secondary school students in Ajman UAE. Materials and Methods: A cross sectional survey was conducted among male secondary school students in Ajman, UAE. A total of 560 participants filled in self-administered questionnaires. Results: The prevalence of ever smokers was 39%; ever dokha smokers was 36% and current dokha smokers was 24%. The prevalence is very high when compared to other forms of smoking in the region and globally. Prevalence increased with increasing age and grade of students, prevalence of ever smokers, ever dokha smokers and current dokha smokers was lower in students in the science stream. 40% of the smokers used dokha, cigarettes and shisha, 30% used dokha and cigarettes, and 21% used dokha alone. 30% of the students smoked dokha on all days of the month. Conclusions: The prevalence of ever smokers, ever dokha smokers and current dokha smokers is very high. There is an urgent need for specific health promotion programs tailored to this age group on prevention of dokha smoking and policies restricting the availability of dokha to this age group.

Objectives: The aim of this study was to investigate the prevalence of metabolically obese, normal-weight (MONW) phenotype and the association between lifestyle factors and the risk of MONW in Korean adolescents. Methods: Normal-weight (BMI, 5th to 85th percentile) subjects with ${\geq}1$ metabolic abnormalities were categorized as MONW phenotype. Data from adolescents aged 12 to 18 years who have participated in the Korean National Health and Nutrition Examination Survey in 1998 (n=751) and 2008 (n=455) were analyzed. Physical activity and dietary intakes were assessed. Results: The prevalence of hypertension and hyperglycemia in 2008 decreased compared with that in 1998 (P<0.001) but the prevalence of abdominal obesity, hypertriglyceridemia and low HDL did not changed. The overall prevalence of MONW in Korean adolescents declined over 10 years (P<0.001). Adolescent boys and girls engaging regular exercise significantly increased over 10 years (P<0.01). Physically active adolescents had a lower risk of being MONW in 1998. Dietary intake patterns were not associated with a risk of MONW. Conclusions: The prevalence of MONW among Korean adolescents declined over 10 years which may be due to the decreased prevalence of hypertension and hyperglycemia. The risk of MONW would be lower in individuals who are physically active.

Objectives : The objective of this study is to assess the prevalence and risk factors of metabolic syndrome (MS) among inpatients with schizophrenia, and to compare with general population. Methods : Nine hundreds seventy inpatients were included to assess the prevalence of MS from two mental hospitals in Yong-in city. Assessment of MS was performed based on modified American Heart Association criteria with abdominal obesity threshold of 90cm for men, 85cm for women. Comparative analysis was performed using age- and gender matched sample from Korea Health and Nutritional Examination Survey III. For evaluating risk factors, analysis included 766 inpatients taking consistent medications at least for 30 days. Results : The prevalence of MS of inpatients with schizophrenia was 26.2%, in females it was 33.2%, compared to 20.2% in males(p < 0.001). Compared to general population, the prevalence of MS was significantly lower in male and higher in female patients. In terms of criteria prevalence, who met abdominal circumference criterion were more prevalent in patient group(p < 0.001). After multivariate analysis, female gender and old age remained as risk factors of MS. Conclusions : The prevalence of MS of inpatients with schizophrenia was 26.2% and significantly low compared to general population. Female gender and old age were risk factors of MS.

Purpose: This study was conducted to estimate the prevalence of asthma and its risk factors in childhood asthma. Method: Random samples of 10,236 were selected from 43 kindergarten (1,418) and 57 elementary (8,718) in K city between september and November (2007). 1,079 (kindergarten children) and 7,271 (elementary children) were in the final analysis. The Korean-translated modified version of the questionnaire for the International Study of Asthma and Allergies in Childhood was used in this cross-sectional survey. Parents were surveyed to answer for the questionnaire. Result: The lifetime and 12-month prevalence of wheezing were 11.50%; 11.06% in kindergarten children and 19.24%; 4.80% in elementary children. The lifetime prevalence of asthma diagnosis and the 12-month prevalence of asthma treatment were 11.59%; 4.43% in kindergarten children and 4.43%; 10.78% in elementary children. The 12-month prevalence of night cough and exercise-induced wheezing were 12.90%; 3.33% in kindergarten children and 20.72%; 4.74% in elementary children. Risk factors analysis showed that age, paternal and maternal asthma, allergic disease, carpet use, monthly income, indoor environment were associated with a higher risk of asthma. Conclusion: The study suggests that prevalence of asthma has increased among the community children. These data have been used to manage a possible role of risk factors as predictors of childhood asthma.
