We conducted this study to determine the factors associated with childhood obesity. The subjects were 170 preschool children in Busan. Data were collected by using questionnaires which asked for information about socioeconomic status, parental perception of their child's weight status and dietary/physical activity behavior. BMI was calculated for each child and their classification was determined, according to their age and sex, as follows: "overweight" at or above the 85th percentile, "normal" for the 15th-85th percentile, and with a BMI below the 15th percentile the children were deemed as underweight. Classification according to BMI percentile showed that 23.5% ($18.25{\pm}1.33\;kg/m^2$) of the children were overweight, 62.9% ($15.51{\pm}0.76\;kg/m^2$) normal, and 13.5% ($13.23{\pm}2.86\;kg/m^2$) were underweight. Socioeconomic status, as represented by the parents' level of education, the occupation of the father and the household income, did not affect the results. However, mothers working outside the household was a factor that was more likely to affect the weight status (p<0.05). Among mothers whose children were overweight, 30% underestimated their children's weight status (believing them to be of normal weight when they were overweight), and 25% failed to recognize the necessity of weight control for their overweight children. While sedentary activity and total daily activity levels were not related to BMI, the level of physically active leisure activity was inversely correlated with BMI (p<0.05). Although there were no differences in total energy intake, dietary behavior was significantly related to weight status. Overweight children had poor eating tendancies: they eat faster (in less than 15 minutes), overeat, and eat late at night. Based on our findings where hereby recommended the following interventions to help limit weight problems in Korean pre-schoolers: early promotion of active leisure behavior and healthy eating habits, along with attempting to correct parental misperception of healthy weight status for children.

Objects: The prevalence of asthma has increased in recent decades globally. The objective of the present study is to elucidate whether hospitalization for bronchiolitis in infancy and low socioeconomic status interact for bronchial hyperreactivity during teenage years. Method: We studied 522 children age 13-14 years attending schools in rural and urban areas to investigate the risk factors for bronchial hyperreactivity (BHR), defined as a provocation concentration of methacholine that causes a decrease of 20% ($PC_{20}$) in forced expiratory volume within 1 second. Clinical examination, skin prick test, spirometry, and methacholine challenge were performed on all study subjects, who provided written consent. We used multivariate logistic regression to investigate the risk factors for BHR, and analyze the interaction between hospitalization for bronchiolitis in infancy and low socioeconomic status. Results: Forty-six (10.3%) positive BHR cases were identified. In the multivariate logistic analysis, as independent predictors of BHR, adjusted odds ratio of bronchiolitis diagnosed before 2 years of age in low income families was 13.7 (95% confidence interval, 1.4 to 135.0), compared to reference group, controlling for age, gender, parental allergy history, skin prick test, and environmental tobacco smoke (ETS) exposure. Interaction was observed between bronchiolitis before 2 years old and low socioeconomic status on children's bronchial hyperreactivity (p-interaction=0.025). Conclusions: This study showed that bronchiolitis diagnosed before 2 years of age and low socioeconomic status interacted on children's bronchial hyperreactivity. Prevention of acute respiratory infection in early childhood in low socioeconomic status is important to prevent BHR as a precursor of asthma.

This study was conducted to assess the nutrient intake patterns among urban and rural adolescents and to investigate the effects due to parent's socioeconomic status and other factors, such as mother's job, family type and regular exercise on that pattern. 2,455 middle and high school students living in Seoul and Yangpong, Kyounffi-Do participated in a self-administered questionnaire that was used to collect data. The one-day dietary intake was surveyed through a 24-hour recall method. The factors significantly different between urban and rural adolescents according to monthly income, parent's education level, mother's job, family type and exercise. Income, the parents' education level and regular exercise were associated with the patterns of nutrient intakes as a percent of the RDA. So, when adjusted for parental income, the father's and mother's education level and regular exercise, there were no signifcant differences within the patterns of nutritional intake between urban and rural adolescents. The results provided the information regarding the determinants of nutrient status among adolescents and were expected to be helpful for planning school health promotion programs.

Objectives: This study was conducted to investigate the prevalence of childhood obesity, the association between the undesirable lifestyles and socioeconomic factors, the association between childhood obesity and various risk factors, including socioeconomic factors, and the agreement between the body mass index (BMI) classification and the body fat percentage. Methods: The study subjects were all the 5th grade students from all the elementary schools in Gunpo City, Kyunggi Province, South Korea (4043 children at 22 schools). The subjects were measured for their height, weight and percent body fat etc. and they were also surveyed by questionnaire from March 18th to April 25th, 2005. To determine whether the children were within normal limits or not, standardized BMIs for each age group were used. The data was analyzed by logistic regression analysis using SAS 9.0 version. Results: The prevalence of childhood obesity prevalence was 25.1 %. Boys had a higher prevalence of obesity (27.5%) than did the girls (22.5%). Children had tendencies of having undesirable lifestyles and getting obese if they had a lower socioeconomic status. The risk factors for childhood obesity were low paternal education (OR: 1.17, 95% CI : 0.97-1.42) and non-parental caregivers (OR: 1.34, 95% CI : 0.98-1.82). Other risk factors for childhood obesity were a high birth-weight, longer TV/computer-using time, a lower fruit-eating frequency, short sleeping hours and parental obesity. The agreement rate between the BMI classification and the body fat percentage was 93.1 %. Conclusions: This study showed the children had a higher prevalence of obesity: further, not only individual lifestyles, but also socioeconomic factors could influence childhood obesity. Childhood obesity was especially more problematic for children with a low socioeconomic status.

Objectives : Most studies about multiple roles and women's health suggested that combining with paid job, being married and having children was more likely to improve health status than in case of single or traditional roles. We investigated whether there was better health outcome in multiple roles among Korean women coinciding with previous studies of other nations. Methods : Data were from the 2005 Korea National Health & Nutritional Examination Survey, a subsample of women aged 25-59 years (N=2,943). Health status was assessed for self-rated poor health, perceived stress and depression, respectively based on one questionnaire item. The age-standardized prevalence of all health outcomes were calculated by role categories and socioeconomic status. Multiple logistic regression was used to assess the association of self rated health, perceived stress, and depression with multiple roles adjusted for age, education, household income, number of children and age of children. Results : Having multiple roles with working role was not associated with better health and psychological wellbeing. Compared to those with traditional roles, employed women more frequently experienced perceived stress, with marital and/or parental roles. Non-working single mothers suffered depression more often than women with traditional roles or other role occupancy. Socioeconomic status indicators were potent independent correlates of self-rated health and perceived stress. Conclusions : Employment of women with other roles did not confer additional health benefit to traditional family responsibility. Juggling of work and family responsibility appeared more stressful than traditional unemployed parental and marital role in Korean women.

Objectives: Adolescent suicide is a global problem. This study aimed to identify associations between parental marital status and suicidal behavior. Methods: This study analyzed 118 715 middle and high school students from the 13th and 14th Korea Youth Risk Behavior Web-based Survey. The odds ratios (ORs) of suicidal ideation, planning, and attempts were calculated based on parental marital status, living situation, and socioeconomic factors. The data were analyzed using multiple logistic regression. Results: When compared to those living with 2 married biological parents, the ORs of suicidal ideation among adolescents living with either remarried or no parents were 1.34 (95% confidence interval [CI], 1.17 to 1.53) and 1.36 (95% CI, 1.11 to 1.66), respectively. For suicidal planning, the OR of those living with 1 remarried biological parent was 1.24 (95% CI, 1.01 to 1.52), and that of those living without parents was 1.28 (95% CI, 0.95 to 1.73), when compared to adolescents living with 2 married biological parents. For suicide attempts, when compared to adolescents with 2 married biological parents, the OR of those living with 1 remarried biological parent was 1.48 (95% CI, 1.17 to 1.87) and that of those living without parents was 2.02 (95% CI, 1.44 to 2.83). For adolescents living with 1 remarried biological parent, suicidal behavior was strongly associated with having no siblings and were weakly associated with not living with grandparents. Conclusions: Suicidal behavior among adolescents was associated with the remarriage and loss of parents. Therefore, special attention and interventions are needed for adolescents in those situations.

Objective : This study examined the socioeconomic differentials for the health and health related behaviors among South Korean middle school students. Methods : A nationwide cross-sectional interview survey of 3,449 middle school second-grade students and their parents was conducted using a stratified multi-stage cluster sampling method. The response rate was 93.3%. The socioeconomic position indicators were based on self-reported information from the students and their parents: parental education, father's occupational class, monthly family income, out-of-pocket expenditure for education, housing ownership, educational expectations, educational performance and the perceived economic hardships. The outcome variables that were measured were also based on the self-reported information from the students. The health measures included self-rated health conditions, psychological or mental problems, the feelings of loneliness at school, the overall satisfaction of life and the perceived level of stress. The health related behaviors included were smoking, alcohol drinking, sexual intercourse, violence, bullying and verbal and physical abuse by parents. Results : Socioeconomic differences for the health and health related behaviors were found among the eighth grade boys and girls of South Korea. However, the pattern varied with gender, the socioeconomic position indicators and the outcome measures. The prevalence rates of the overall dissatisfaction with life for both genders differed according to most of the eight socioeconomic position indicators. All the health measures were significantly different according to the perceived economic hardship. However, the socioeconomic differences in the self-rated health conditions and the psychosocial or mental problems were not clear. The students having higher socioeconomic position tended to be a perpetrator of bullying while those students with lower socioeconomic position were more likely to be a victim. Conclusions : The perceived economic hardships predicted the health status among the eighth graders of South Korea. The overall satisfaction of life was associated with the socioeconomic position indicators. Further research efforts are needed to explore the mechanisms on how and why the socioeconomic position affects the health and health related behaviors in this age group.

Purpose: Obesity is one of the most common health problems among children and its prevalence has increased in recent decades. Socioeconomic status (SES) is a well-known risk factor for childhood obesity although the associations were different across countries. Previous studies in other countries have reported a positive association between childhood obesity and SES in developing countries, and inverse correlation has been reported in developed countries. For this reason, we wanted to investigate the relationship between SES and obesity in Korean children. Methods: Data were acquired 3,095 boys and girls who participated in the fifth Korea National Health and Nutrition Examination Survey, which was conducted from 2010 to 2012. Body mass index was calculated from measured anthropometric data using the 2007 Korean National Growth Charts. Results: Upon univariate analysis, we did not find any statistically significant differences in the parental employment status, monthly family income between children with and without obesity. Multiple logistic regression analysis showed childhood obesity was positively associated with maternal overweight (OR, 1.889; 95% CI, 1.079-3.309), maternal obesity (OR, 3.409; 95% CI, 2.228-5.215) and paternal obesity (OR, 2.135; 95% CI, 1.257-3.627). Conclusion: The present study showed that socioeconomic status might not an important risk factor for obesity in Korean children. These results warrant further studies to clarify the association between SES and obesity in Korean children.
