The aim of this study was to investigate the prevalence and correlates of depressive symptoms in the largest number of Korean individuals examined to date. We analyzed cross-sectional data collected from 229,595 Korean adults aged 19 yr and above who participated in a Korean Community Health Survey conducted in 2009. The Center for Epidemiologic Studies Depression Scale (CES-D) was used as the measurement tool for depressive symptoms (CES-D score over 16) and definite depression (CES-D score ove

This study aimed to estimate nationwide prevalence of the metabolic syndrome and to identify its association with cardiovascular diseases. The data on a national rep-resentative sample of 6,147 adults from 1998 Korea National Health and Nutrition Survey were analyzed. The syndrome was determined according to two kinds of modified definition from ATP III, in which abdominal obesity was determined by waist circumference (WC) standard for Asians and waist-to-hip ratio (WHR). Based on the former, pr

In January 2008, an outbreak of acute gastroenteritis at a waterpark was reported to the Bundang-gu Public Health Center in Seongnam, Korea. To determine the etiological agent and mode of transmission, a retrospective cohort study was done using structured questionnaires and stool samples from patients who had current gastrointestinal symptoms and three food handlers were tested. A total of 67 (31.0%) students and teachers developed acute gastroenteritis. No food items were associated with an in

This study compared interview and telephone surveys to select the better method for regularly estimating nationwide vaccination coverage rates in Korea. Interview surveys using multi-stage cluster sampling and telephone surveys using stratified random sampling were conducted. Nationwide coverage rates were estimated in subjects with vaccination cards in the interview survey. The interview survey relative to the telephone survey showed a higher response rate, lower missing rate, higher validity a

BACKGROUND/OBJECTIVES: The inverse relationships of combined fruits and vegetables intake with blood pressure have beenreported. However, whether there are such relationships with salty vegetables has rarely been investigated in epidemiologicstudies. We evaluated the relation of combined and separate intake of fruits, vegetable intakes, and salty vegetables, as wellas sodium and potassium, with blood pressure among the middle-aged and elderly populations. SUBJECTS/METHODS: The present cross-sect

The objective of this study was to identify the factors that determine serum homocysteine concentrations in Korean population. In a community-based study, 871participants completed detailed questionnaires and physical examination. We found that increased age, male sex, family history of stroke, deficiencies of serum folate and vitamin B12, and elevated serum creatinine significantly increased the risk of hyperhomocysteinemia. However, hormonal and behavioral factors (smoking, alcohol drinking, c

This study analyzes the food frequency for the elderly regarding different family types and finds the factors for nutritional risk, offers a basic reference for providing nutritional support for them. The study referred to the dietary behavioral survey data of 3,680 elderly people (1652 male and 2028 female) from 21 regions in the northern Kyeonggi province. The data was collected through the method of one-to-one interviews and was a part of the Community Health Survey for 2008 by the Korea Cent

도시는 물리적환경과 인구·사회·경제 등의 복잡하고 다양한 요소들이 섞여 있는 공간이며, 사람들의 정신건강에도 영향을 줄 수 있다. 사람들의 정신건강에 영향을 미치는 주요 요인은 성격, 소득, 직업, 가족들과의 관계 등 내부적 요인과 물리적환경과 같은 외부적 요인이 있다. 따라서 본 연구의 목적은 사람들의 우울에 영향을 미치는 개인과가구특성뿐만 아니라 근린의 물리적 환경 특성을분석하여 거주민의 정신건강을 증진하기 위한 정책적 시사점을 제공하는 것이다.

Background/Aims: The frequencies of opportunistic diseases (ODs) vary across countries based on genetic, environmental, and social differences. The Korean HIV/AIDS cohort study was initiated in 2006 to promote research on human immunodeficiency virus (HIV) infection in Korea, and to provide a logistical network to support multicenter projects on epidemiological, clinical, and laboratory aspects of HIV infection. This study evaluated the prevalence of ODs among HIV-infected patients in the era of

This study aimed to examine whether a dose-response relationship exists between psychological distress and types of physical activity (total, occupational, and leisuretime). The study subjects (233 men and 313 women) were recruited for a study on cardiovascular disease in the Yangpyeong community located in South Korea. The type and characteristics of physical activity were measured with a modified version of the Stanford 5 city project’s questionnaire by well-trained interviewers using a standa

Currently, metabolic complications are the most common problem among human immunodeficiency virus (HIV)-infected patients, with a high incidence. However, there have been very few studies regarding metabolic abnormalities published in Asia, especially in Korea. This cross-sectional study was performed to investigate the prevalence of and risk factors for metabolic abnormalities in 1,096 HIV-infected patients of the Korea HIV/AIDS cohort study enrolled from 19 hospitals between 2006 and 2013. Dat

Purpose: The number of benign prostatic hyperplasia (BPH) subjects has been increasing worldwide, and many studies have been conducted to determine the treatment that can delay drug therapy or surgery. Subsequently, most of these studies involved physical activity (PA) and associated factors. Therefore, we aimed to determine factors associated with BPH prevalence based on a review of past and present studies and to investigate the effect of a healthy lifestyle as a protective factor of BPH occur

The number of persons infected by HIV/AIDS has consistently increased in Korea since the first case of HIV/AIDS infection in 1985 and reached 15,208 by 2016. About 1,100 new patients with HIV/ AIDS infections have emerged every year since 2013. In Korea, the Korea HIV/AIDS Cohort Study was established for the evidenced-based prevention, treatment, and effective management of patients infected with human immunodeficiency virus (HIV) in December 2006. This study monitored 1,438 patients, who accou

Since the early 1990s, Korea has made efforts to strengthen its National Communicable Disease Control System. In 2005, the Korea...
