Objective : To develop a boner understanding of the relationship between weight status and the prevalence of obesity related diseases in the Korean population. Methods : The 1998 Korean National Health and Nutrition Survey was used and 10,880 persons who had previously taken health examinations were selected for study. The Korean Society for the Study of Obesity's classification of weight status was used. Hypertension, diabetes mellitus, dyslipidemia, osteoarthritis, chronic heart disease, stroke were included as obesity related disease. A logistic regression model was developed to estimate the prevalence odds ratio by obesity class adjusted for demographic and socioeconomic factors and we converted the odds ratio to a prevalence ratio using the base line prevalence of disease to aid in the interpretation of the ratios. Results : The prevalence of obesity was 26.3% based on the KSSO classification $(BMI\geq25)$. A graded increase in the prevalence ratio was observed with increasing severity of overweight and obesity for all health outcomes with the exception of chronic heart disease in men and stroke in both men and women. With normal weight individuals as the reference, for men who were younger than 50 years, the prevalence ratios were highest for hypertension BMI<23-25: 1.70(95% CI=1.41-2.05), 25$BMI\geq30$: 4.83(95% CI=3.70-5.84). The prevalence ratios for dyslipidemia were as high as hypertension, but were lower than hypertension for diabetes mellitus and osteoarthritis. Prevalence ratios generally were greater in younger adults. The prevalence of having 2 or more obesity related diseases increased with weight status category, except in people who were older than 50 years. Conclusions : Based on results, obesity is an increasingly important health problem in Korea and the disease burden increases according to weight status. For Korean adults, the strongest relationship was seen between weight status and hypertension and dyslipidemia. In older people the impact of excess weight and obesity is stronger than that seen in younger people. Increased efforts in the study of obesity and prevention and treatment of obesity and obesity related disease are required.
The prevalence of childhood obesity is increasing worldwide at an alarming rate. While obesity is known to increase a variety of cardiovascular and metabolic diseases, it also acts as a risk factor for the development and progression of chronic kidney disease (CKD). During childhood and adolescence, severe obesity is associated with an increased prevalence and incidence of the early stages of kidney disease. Importantly, children born to obese mothers are also at increased risk of developing obesity and CKD later in life. The potential mechanisms underlying the association between obesity and CKD include hemodynamic factors, metabolic effects, and lipid nephrotoxicity. Weight reduction via increased physical activity, caloric restriction, treatment with angiotensin-converting enzyme inhibitors, and judicious bariatric surgery can be used to control obesity and obesity-related kidney disease. Preventive strategies to halt the obesity epidemic in the healthcare community are needed to reduce the widespread deleterious consequences of obesity including CKD development and progression.
Obesity is correlated with diabetes mellitus, hyperlipidemia, hypertension, cardiovascular, renal, neurologic, psychological and many other disease. Owing to the elevated income and behavioral changes, the prevalence of obesity has remarkably increased in Korea also. Considering the trend of the epidemic, we can easily expect the excessive spendings for the treatment of the obesity-related diseases in near future. In order to check the prevalence of obesity and serum lipid levels of Korean employees, we analyzed the medical check-up sample data of 10,332 adults who took physical check-ups at an institute in 2006. Through the logistic regression analysis we found the prevalence rate of total risk group showing ${\geq}23.0Kg/m^2$ was 57.4% and uric acid was found to be a definitive factor in the prevalence of obesity. Among the adults who eat more meat, drink more and smoke more smoking, the values of BMI, uric acid, cholesterol, HDL- and LDL-cholesterol and TG were significantly higher than rest of the examinees. And the average BMIs were significantly higher among those who have risk factors of liver disease, hypertension, cardiovascular and heart disease, and diabetes mellitus.
Purpose: The purpose of this study was to investigate factors related to obesity of mid-age women and to examine the relationship between obesity and chronic diseases including diabetes, hypertension, and heart disease. Methods: Using data from Korean American adults living in California, we analyzed the health behavior (diet, exercise, smoking, and binge drinking) and psychological stress of obese women with body mass index ${\geq}25$ by using chi-square test. Logistic regression was used to investigate independent effects of obesity on chronic diseases, after controlling for risk factors. Results: The prevalence of obesity appeared about 16.9%. The Obese group was less likely than the non-obese group to eat vegetables and more likely feel psychological stress. There were no significant differences in smoking, alcohol intake, and physical exercise between the two groups. Obesity was strongly related to chronic diseases (OR=4.642, 95% CI=1.328-16.222). Conclusion: This study suggests that obesity of mid-age women could be reduced by encouraging health behavior such as eating vegetables daily, performing physical exercise regularly, and taking care of emotional stress. Diet and physical activity interventions and emotional supports should be developed for weight loss and prevention of weight gain in mid-age women.
Objectives: Metabolic disease is strongly associated with future insulin resistance, and its prevalence is increasing worldwide. Thus, identifying early biomarkers of metabolic-related disease based on serum profiling is useful to control future metabolic disease. Our study aimed to assess the association of serum branched chain amino acids (BCAAs) and aromatic amino acids (AAAs) ratio and metabolic disease according to body mass index (BMI) status among Korean adults. Methods: This cross-sectional study included 78 adults aged 20-59 years in Korea. We compared serum amino acid (AA) levels between adults with normal-weight and adults with obesity and investigated biomarkers of metabolic disease. We examined serum AA levels, blood profile, and body composition. We also evaluated the association between serum AAs and metabolic-related disease. Results: The height, weight, BMI, waist circumference, hip circumference, waist-hip-ratio, body fat mass, body fat percent, skeletal muscle mass, systolic blood pressure, and diastolic blood pressure were higher in the group with obesity compared to normal weight group. The group with obesity showed significantly higher levels of BCAA, AAA, and BCAA and AAA ratio. Further, BCAA and AAA ratio were significantly positively correlated with triglyceride, body weight, and skeletal muscle mass. The evaluation of metabolic disease risks revealed an association between the ratios of BCAAs and AAAs, hypertension, and metabolic syndrome. Conclusions: Our study is showed the associations between BCAA and AAA ratio, obesity, and obesity-related diseases using various analytical approaches. The elevated BCAA and AAA ratio could be early biomarkers for predicting future metabolic diseases in Korean population.
Purpose : Obesity is, along with metabolic syndrome, closely related with nonalcoholic fatty liver disease. This study tried to evaluate the prevalence of nonalcoholic liver disease in obese children and verify the factors associated with the disease. Methods : Two hundred and seventy nine children who showed a body mass index of 95 percentile over the baseline in health examinations of surrounding schools were evaluated. Questionnaires, body measurements, blood examinations, and ultrasonographic measurements of abdominal fat were examined. Results : Out of 279 children enrolled for the study, 27 children were found to possess nonalcoholic liver disease(9.7%). Among those found to be positive for nonalcoholic liver disease, it's prevalence increased to 15.2%(22 out of 144 children) among children with severe obesity. Factors known to be involved with metabolic syndrome, namely waist/hip circumference ratio and thickness of abdominal fat, were found to be closely related to nonalcoholic fatty liver as well. Conclusion : The prevalence of nonalcoholic fatty liver in obese children was 9.7%, with higher incidence observable in severer obesity. Factors responsible for metabolic syndrome were closely associated with nonalcoholic fatty liver disease, and the level of insulin resistance, which is an useful index in both diseases, can be utilized in evaluation of the effect of treatment and control of risk factors.

Objectives: Obesity is a considerable and growing public health concern worldwide. The present study aimed to quantify socioeconomic inequalities in adult obesity in western Iran. Methods: A total of 10 086 participants, aged 35-65 years, from the Ravansar Non-communicable Disease Cohort Study (2014-2016) were included in the study to examine socioeconomic inequalities in obesity. We defined obesity as a body mass index ${\geq}30kg/m^2$. The concentration index and concentration curve were used to illustrate and measure wealth-related inequality in obesity. Additionally, we decomposed the concentration index to identify factors that explained wealth-related inequality in obesity. Results: Overall, the prevalence of obesity in the total sample was 26.7%. The concentration index of obesity was 0.04; indicating that obesity was more concentrated among the rich (p<0.001). Decomposition analysis indicated that wealth, place of residence, and marital status were the main contributors to the observed inequality in obesity. Conclusions: Socioeconomic-related inequalities in obesity among adults warrant more attention. Policies should be designed to reduce both the prevalence of obesity and inequalities in obesity by focusing on those with higher socioeconomic status, urban residents, and married individuals.
Objectives : Non-alcoholic fatty liver disease (NAFLD) is known to be increasing and becoming a health-related issue worldwide. This study aimed to analyze its prevalence and characterize NAFLD. Methods : NAFLD-related papers were surveyed via PubMed and in Korean medical journals, and then the prevalence and pathology were reviewed. Results : The prevalence of NAFLD in the general population is around 10~30% worldwide. The prevalence of NAFLD in Korea is estimated as 15~30%, which is higher than in China and Japan. The most important etiological-factors of NAFLD include central obesity resulting from excessive calorie intake and less physical activity, which lead to adiponectin hypoactivity and insulin resistance. The Oriental medicine view point of NAFLD pathology is phlegm-dampness by dysfunction of free flow in liver. Conclusions : This study provided an overview of the prevalence and pathology of NAFLD, and can support the development of a strategy for traditional Korean medicine-based prevention or treatment of NAFLD.
Purpose: The purpose of this paper was to compare community health status by region and to investigate related factors using community health and social indicators. Methods: Data were collected from statistics of local districts that were provided by KNSO and KCDC. ANOVA and correlation were analyzed using PASW 18.0. Results: The standardized cancer mortality rate was higher in metropolitan areas than in other areas. On the contrary, the mortality of respiratory disease, traffic accident, and suicide were higher in rural areas. Small cities and county districts showed higher prevalence in obesity prevalence than metropolitan areas. Metropolitan areas presented higher prevalence in alcohol drinking during the previous month, perceived stress, and seat belt use. The age-adjusted standardized mortality rate was correlated with higher prevalence of smoking, obesity, percentage of the elderly, number of beds, number of social welfare facilities, number of registered cars, lower percentage of financial independence, number of doctors, and percentage of water supply service & sewage. Conclusion: Since significant differences in mortality rate and prevalence of health risk behaviors exist between regional areas and the mortality rate was correlated with other social indicators and health indicators, health policies and social policies considering these differences should be develop and implemented to the communities.
Objective : To estimate the socioeconomic costs of obesity in Korea,1998. Methods : The 1998 National Health and Nutrition Examination Survey(1998 NHNES) data was used and 10,880 persons who had taken health examinations were selected for study. Essential hypertension, NIDDM(non insulin-dependent diabetes mellitus), dyslipidemia, osteoarthritis, coronary heart disease, stroke were included as obesity related disease. The data of direct costs of obesity was obtained from the National Federation of Medical Insurance. The category of indirect costs was the loss of productivity caused by premature death and admission, time costs, traffic costs, nursing fees due to obesity. Multiple logistic regression model was developed to estimate prevalence odds ratio by obesity class adjusted demographic and socio-ecnomic factors and calculate PAF(Population Attributable Fraction) of obesity on obesity related disease. And we finally calculated the socioeconomic costs of obesity in relation to BMI with PAF. Results : The direct costs of obesity were 2,126 billion${\sim}965$ billion Won in considering out of pocket payment to uninsured services, and the indirect costs of obesity were 2,099 billion${\sim}1,086$ billion Won. Consequently, in considering out of pocket payment to uninsured services, the socioeconomic costs of obesity were 4.225 billion${\sim}2,050$ billion Won, which corresponded to about $0.094%{\sim}0.046%$ of GDP and $1.88%{\sim}0.91$ of total health care costs in Korea. Conclusions : Obesity represents a major health problem with significant economic implications for the society. This results are conservative estimates as far as all obesity related disease and all health care and indirect costs were not included due to missing information. further studies are needed to caculate socioeconomic costs of obesity more exactly.
