Factors contributing to educational differences in obesity among women: evidence from South Korea.

Background: Obesity is more prevalent among less-educated women than highly-educated women around the world. However, little is known about the factors which cause this difference in obesity, and almost nothing is known about how the individual factors which explain differences in education among women alone contribute to obesity. In this study, we identified the factors which help explain the relationship between education and obesity in women, and quantified their separate contributions to obesity.

Sex-specific role of education on the associations of socioeconomic status indicators with obesity risk: A population-based study in South Korea.

Background: No study of obesity risk for people in developed countries has conducted a multi-dimensional analysis of the association of socioeconomic status with obesity. In this paper, we investigated if education functions as either a confounder or an effect modifier in the association of another socioeconomic status indicator with obesity.

Methods: This cross-sectional study analyzed data of an adult population sample (10,905 men and 14,580 women) from the Korea National Health and Nutrition Examination Survey (2010-2014).

Gender-specific interactions between education and income in relation to obesity: a cross-sectional analysis of the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V).

Objectives: To identify gender-specific associations between education and income in relation to obesity in developed countries by considering both the interaction-effect terms of the independent variables and their main-effect terms.

Design: A cross-sectional study. Education and income levels were chosen as socioeconomic status indicators.

Modifying effects of education on the association between lifestyle behaviors and the risk of obesity: evidence from South Korea.

Background: No previous study has explored the interactions between education and lifestyle in relation to obesity. This study hypothesized that education may be obesogenic through its interplay with lifestyle behaviors.

Methods: Data for a nationally representative sample (6937 men and 9333 women) from the Korea National Health and Nutrition Examination Survey (2010-2012) were analyzed.

The socioeconomic burden of coronary heart disease in Korea.

Objectives: We aimed to estimate the annual socioeconomic burden of coronary heart disease (CHD) in Korea in 2005, using the National Health Insurance (NHI) claims data.

Methods: A prevalence-based, top-down, cost-of-treatment method was used to assess the direct and indirect costs of CHD (International Classification of Diseases, 10th revision codes of I20-I25), angina pectoris (I20), and myocardial infarction (MI, I21-I23) from a societal perspective.

Results: Estimated national spending on CHD in 2005 was $2.

Why is high-risk drinking more prevalent among men than women? Evidence from South Korea.

Background: It is important to identify and quantify the factors that affect gender differences in high-risk drinking (HRD), from both an academic and a policy perspective. However, little is currently known about them. This study examines these factors and estimates the percentage contribution each makes to gender differences in HRD.

Differences between the factors affecting high-risk drinking and those affecting smoking in Korea.

This study examines the factors influencing high-risk drinking and cigarette smoking and assesses the differences in those factors between 2 risky behaviors in Korea. A national, cross-sectional health behavior survey was performed on 12,303 households in 2006 and a data set of 2925 adult males was analyzed using bivariate probit estimation model. The likelihood of high-risk drinking rose with an increase in the level of income, whereas that of smoking was lowest in a medium income.

Estimating the lifetime economic burden of stroke according to the age of onset in South Korea: a cost of illness study.

Background: The recently-observed trend towards younger stroke patients in Korea raises economic concerns, including erosion of the workforce. We compared per-person lifetime costs of stroke according to the age of stroke onset from the Korean societal perspective.

Methods: A state-transition Markov model consisted of three health states ('post primary stroke event', 'alive post stroke', and 'dead') was developed to simulate the natural history of stroke.

Economic burden of injuries in South Korea.

Unlabelled: BACKGROUND STUDIES: on the cost of injury are useful in setting research and policy priorities and it is valuable to observe differences in the economic burden of injuries across countries.

Objective: To estimate the treated prevalence rate, economic burden and gender- and age-specific costs of injuries in Korea in 2006.

Design: Annual direct healthcare costs associated with injuries were estimated from the National Health Insurance, Medical Aid and Automobile Insurance databases.

Factors influencing gender differences in smoking and their separate contributions: evidence from South Korea.

This paper explores gender differences in smoking using information on 15,277 adults obtained from the Korea National Health and Nutrition Examination Surveys of 2001 and 2005. Applying a decomposition approach extended from the Oaxaca-Blinder method, we obtained factors influencing gender differences in smoking and estimated their separate contributions. According to the outcomes of decomposition analyses, gender differences in smoking-tendency (or inclination to smoke) accounted for 98% of the total gender difference in smoking.

[Socioeconomic inequity in self-rated health status and contribution of health behavioral factors in Korea].

Objectives: The study is investigated socioeconomic variations in self-rated health status and contribution of health behavioral factors in Korea.

Methods: A nationally representative sample (2,800 men and 3,230 women aged 20-64 years) from the 2005 Korea National Health and Nutrition Surveys was analyzed using logistic regression.

Results: Self-rated health was lower among lower socioeconomic groups compared with higher socioeconomic groups, with gender being irrelevant.

Factors influencing cigarette smoking and quantified implications for anti-smoking policy: evidence from South Korea.

Objectives: The aim of this study was to determine the factors that are associated with adult males' smoking in South Korea and simulate the effects of a potential anti-smoking policy.

Methods: We conducted a national, cross-sectional, telephone survey among males aged 20 years and older in 2006 and analyzed a dataset of 2,847 subjects by using the full information maximum likelihood sample selection model.

Results: The likelihood of smoking was highest among the wealthy, employed, Christian, or people who exercise regularly.

The influence of housing tenure and marital status on smoking in South Korea.

Objective: This study aimed to identify the most influential socioeconomic indicator of smoking in South Korea.

Methods: This study analyzed a nationally representative sample (6141 men and 7133 women aged 20-65) from the 2001 and 2005 Korea National Health and Nutrition Surveys. Weighted estimates were computed, adjusting for a complex survey design using "surveyfreq" and "surveylogistic" procedures of SAS 9.

[Socioeconomic costs of stroke in Korea: estimated from the Korea national health insurance claims database].

Objectives: To estimate the annual socioeconomic costs of stroke in Korea in 2005 from a societal perspective.

Methods: We identified those 20 years or older who had at least one national health insurance (NHI) claims record with a primary or a secondary diagnosis of stroke (ICD-10 codes: I60-I69, G45) in 2005. Direct medical costs of the stroke were measured from the NHI claims records.

[Analysis of willingness-to-quit cigarette price among Korean male adults].

Objectives: The purpose of this study was to estimate the willingness to quit cigarette price among Korean male adults, and to examine he factors affecting the willingness to quit cigarette price.

Methods: The data was collected by a random digit dial telephone survey. 702 samples were analyzed by using t-tests, ANOVA and OLS regression analysis.

[The effect of cigarette price on smoking behavior in Korea].

Objectives: To determine the impact of cigarette prices on the decision to initiate and quit smoking by taking into account the interdependence of smoking and other behavioral risk factors.

Methods: The study population consisted of 3,000 male Koreans aged > or =20. A survey by telephone interview was undertaken to collect information on cigarette price, smoking and other behavioral risk factors.
