Purpose: The purpose of the present study was to identify prevalence of excessive daytime sleepiness(EDS) and its associations with sleep habits, sleep problems, depression, subjective health status and obesity in community dwelling adults. Method: Data was collected from adults aged 20-59 years by random sampling. Subjects completed a questionnaire which was composed of the Epworth Sleepiness Scale, Center for Epidemiologic Studies Depression Scale, and questions that included items about sleep habits, sleep problems, subjective health status and sociodemographic characteristics. Height and weight were measured for calculation of body mass index. The statistical analyses was based on 3,302 adults (51.5% males and 48.5% females). Descriptive statistics, univariate logistic regression and multiple logistic regression were used. Result: The prevalence of EDS was 17.1% Multiple logistic regression showed that the associated factors of EDS were depression, obesity, dissatisfaction with sleep time, irregular sleep, and habitual snoring. Depression was the most significant associated factor(adjusted odds ratio for severe depression=2.27, 95% Confidence Interval=1.73-2.96). Conclusion: EDS is a common symptom in adults. Our finding suggested that persons with a complaint of EDS should be completely assessed for depression and obesity as well as sleep problems.
This study was performed to investigate the differences in food choice, nutrition labeling perceptions, and prevalence of obesity due to meal skipping in Korean elementary school children. A national survey was performed in 2010 to collect data on food intake frequency, understanding of nutrition labeling, and body mass index from 2,335 fifth grade students in 118 elementary schools selected from 16 metropolitan local governments by stratified cluster sampling. The data were analyzed using the SAS 9.1 and SUDAAN 10.0 packages. Students who consumed three meals for 6-7 days during the past week were classified into the regular meal eating (RM) group (n = 1,476) and those who did not were placed into the meal skipping (MS) group (n = 859). The daily intake frequency of fruits, vegetables, kimchi, and milk was significantly lower in the MS group compared to that in the RM group (P < 0.001), whereas the daily intake frequency of soft drinks and instant noodles (ramyeon) was significantly higher in the MS group than that in the RM group (P < 0.05). The MS group demonstrated a significantly lower degree of understanding with regard to nutrition labeling and high calorie foods containing low nutritional value than that in the RM group. The distribution of obesity based on the percentile criteria using the Korean growth chart was different between the MS and RM groups. The MS group (8.97%) had a higher percentage of obese subjects than that in the RM group (5.38%). In conclusion, meal skipping was related to poor food choice, low perception of nutrition labeling, and a high prevalence of obesity in Korean fifth grade children.
The purpose of this study was to determine the prevalence of obesity and to examine the eating habits of elementary school students in Kwangju. The study was carried out on 931 students(male : 454, female : 477) in September and October of 1996. The results are summarized as follows ; Obesity was defined as body mass index(BMI) that exceeds 20. The rate of obesity was 10.0%(male 4.7$\%$, female 5.3$\%$) in subjects. Subjects were divided into 3 groups : normal group(BMI〈20), mildly obese group(20〈BMI〈25), and moderatly obese group(25〈BMI〈30), respectively. With regard to frequency of skipping breakfast, 9.1$\%$ of normal children and 17.5$\%$ of mildly obese children and 33.3$\%$ of moderately obese children had skipping every morning(p$\ll$0.001). With regard to the regularity of meal time, 62.1$\%$ of normal children had ‘regular meals’but 58.0$\%$ of mild obese children and 50.0$\%$ of moderate obese children had‘irregular meals’(p$\ll$0.05). With regard to meal volume, obese children consumed much more meal volume than normal children(breakfast p$\ll$0.001, lunch p〈0.005, dinner p$\ll$0.001). With regard to try to lose weight, 22.9$\%$ of normal children and 55.6$\%$ of mild obese children and 83.3$\%$ of moderated obese children indicated they had attempted(p$\ll$0.001). The results of this study showed that the prevalence of obesity in elementary school students in Kwangju has a tendency to be increased. Obese children need to correct their eating habits. This reasserts the importance of nutrition education in children through teachers, parents and dietitians. The findings of this study should be applied to nutrition education to ensure better physical fitness of children. (Korean J Community Nutrition 2(4) : 486-495, 1997)

Background: In postmenopausal women, there is rapid bone loss due to estrogen depletion. In women, reproductive factors such as age at menarche, breastfeeding, and parity are considered risk factors of osteoporosis. Many reports suggest that obesity is associated with a reduced risk of osteoporosis. This nationwide, population-based study aims to identify the association between maternal age and osteoporosis risk in postmenopausal women of different obesity classifications. Methods: We assessed data from the Korean National Health and Nutrition Examination Survey 2010-2012. The study included 1,328 postmenopausal women, after excluding women with missing data for reproductive history among 4,546 postmenopausal women in the survey. Multivariate regression was used to identify the association between childbirth age and postmenopausal bone mineral density after adjustments for confounding factors. Results: The prevalence of postmenopausal osteoporosis was 35.24% (n = 468). After dividing the subjects into obese and non-obese groups based on body mass index (BMI) and waist circumference, there were significant differences between non-osteoporosis and osteoporosis groups with regard to age at first childbirth, age at last childbirth, and parity in the BMI-based general obesity group. The prevalence of osteoporosis was highest in women older than 35 years old at last childbirth. The prevalence of osteoporosis was also greater in women with parity ${\geq}4$ compared to those with lower parity levels. Conclusion: Postmenopausal women of older age at last childbirth and higher parity were at increased risk of osteoporosis in the BMI-based non-general obesity group.

Purpose: This study was conducted to differentiate the factors associated with the BMI group of adolescents between rural and urban areas, and provide baseline data in the development of health education programs considering their personal and environmental characteristics. Methods: Secondary data analysis was performed using the data from an on-line survey of the 9th adolescence behavioral health in 2013. The instruments included general, behavioral, and psychosocial characteristics. This study was a cross-sectional survey conducted with 26,513 adolescents. The data were analyzed using a t-test, two-way ANOVA, and multinomial logistic regression analysis. Results: Significant differences in the prevalence of obesity between urban and rural areas were nated and rural areas exhibited a higher prevalence of obese adolescents (p<0.05). The factors associated with the BMI group were the mothers' education level (low) and lower age of adolescents (middle school) in rural areas, wherase those for urban areas were gender (boys) and the fathers' education level (low) (p<0.05). Conclusion: Because there was a significant difference in the prevalence of obesity between rural and urban areas, it is necessary to develop a tailored education program considering the regional and environmental characteristics that the adolescents belonged to in order to prevent and control adolescent obesity.
Objectives: The purpose of this study is to identify prevalence and related factors of the elderly, who took health examination, with metabolic syndrome. Methods: The health examination and lifestyle survey were performed for 21,512 adults at 60 years of age or older who took health examination in H health promotion center during January-March 2009. Results: The prevalence of metabolic syndrome for the subject was 24.0%. Of the subject with metabolic syndrome, the prevalence of the diseases was obesity 60%, abdominal obesity 78.5%, hypertension 82.6%, dyslipidemia 89.7% and diabetes 51.9%. In comparison of the relationship between metabolic syndrome and other diseases, the male subject with metabolic syndrome were significantly higher in BMI, waist circumference, systolic/diastolic blood pressure, hemoglobin, AST, ALT, $\gamma$-GTP, TG, AC glucose, creatinine than normal male(p<0.001). In comparison of the relationship between metabolic syndrome and lifestyle, more drinking frequency and amount in male and more drinking frequency in female were associated with increased risk of metabolic syndrome(p<0.01). Regardless of exercise intensity, practice of exercise contributed to reduce the risk of metabolic syndrome(p<0.01). Conclusion: In conclusion, TLC program, focused on lifestyle behaviors which is strongly associated with the prevalence of metabolic syndrome, should be developed for the improvement of life quality in the elderly with metabolic syndrome.
Objectives: The purpose of this study was to estimate the prevalence of metabolic syndrome (MS), metabolic abnormalities, and nutrient intakes in Korea children and adolescents using the Korea National Health and Nutrition Examination Survey from 2008. Methods: A sample of 838 children and adolescent males (n=442) and females (n=396) aged 10-18 was used from the 2008 Korea National Health and Nutrition Examination survey. The diagnosis of the metabolic syndrome subjects was adapted from modified National Cholesterol Education Program-Adult Treatment Panel III by Ford. To compare nutrient intakes, we used a judgment sampling. The first group was composed of all children and adolescents (n=46) with MS. The second one along with the first group had children and adolescents with the same age, sex, and body mass index (BMI) but without MS (n=46). The control group like the first two had children and adolescents with same sex and same age but with normal BMI and without MS (n=46). Results: In this randomized controlled controlled trial, the prevalence of the metabolic syndrome was 5.8%. The risk factors was associated with the MS were abdominal obesity 9.4%, hypertriglyceridemia 25.0%, low HDL-cholesterol 10.3%, hypertension 23.4%, and hyperglycemia 7.1%. Among metabolic abnormalities, blood pressure was significantly affected by sex, age and obesity. On the other hand, HDL-cholesterol, triglycerides, and waist circumference were directly linked to obesity. There were no significant differences in nutrient intakes among the three groups. Conclusions: The prevalence of MS was higher in children (10-11 years old) than in adolescents (12-18 years old). There was a difference in hypertension among risk factors by gender, and there were no significant differences in nutrient intakes.
Purpose: We evaluate the influence of the types of coffee beverage on obesity and abdominal obesity in Korean adults who were aged 19 years or over by using the 2013 ~ 2016 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: Specific questions were asked about frequency of coffee intake, the type of coffee beverage, the addition of milk and/or sugar to coffee by using the food frequency questionnaire of the 2013 ~ 2016 KNHANES. Results: We found that coffee intake increased the prevalence of obesity and abdominal obesity. After multivariable adjustment, coffee consumption increased the risk of obesity by 1.30 (95% CI: 1.08 ~ 1.57) in the group that drank coffee twice a day, and 1.33 (95% CI: 1.11 ~ 1.60) in the people who drank coffee ${\geq}3$ times a day as compared to that of the non-coffee intake group. The risk of abdominal obesity increased to 1.27 (95% CI: 1.02 ~ 1.57) in the < 1 time/day coffee drinking group, 1.34 (95% CI: 1.08 ~ 1.66) in the 1 time/day coffee drinking group, 1.35 (95% CI: 1.09 ~ 1.67) in the 2 times/day coffee drinking group, and 1.40 (95% CI: 1.14 ~ 1.72) in the ${\geq}3$ times/day coffee drinking group as compared to that of the non-coffee drinking group. The influence of black coffee intake was different according to gender: males showed a high prevalence of abdominal obesity and females showed a high prevalence of obesity. Mixed coffee consumption increased the risk of obesity and abdominal obesity by more than 34% in men who consumed coffee more than 3 times a day and in women who consumed coffee more than 2 times per day. Conclusions: We found that coffee intake, regardless of the type of coffee, increased the prevalence of obesity and abdominal obesity. It is necessary to refrain from drinking coffee to prevent obesity.
This study was carried to estimate the prevalence of obesity and to investigate the relationship between stress and obesity in children. The subjects were 508 children, who were randomly selected from the fifth and sixth grade at nine elementary schools in Kangnung. The height, body weight, waist and hip circumferences and body fat(%) were measured and the levels of stress were assessed by a questionnaire consisting of the following 3 domains ; 4 items for personal factors, 11 for home, and 18 for school. The prevalence of obesity in male and female children greatly varied by the indices from 2.5% and 1.7% when judged by BMI, 9.5% and 4.0% by obesity index, and 29.7% and 34.4% by body fat(%). The stress scores from personal(47.1%) and school (47.9%) factors were higher than the stress score from home(38.5%). The stress score from personal factors of female children is significantly higher than that of male children, but the stress score from home of female children is significantly lower than that of male children. The personal stress score and the total stress score of obese female children were significantly higher than those of non-obese female children. In male children, the obesity index(%) or body fat(%) have a significant positive correlation with the stress scores from over-expectation of parents, a lack of conversation with family, examinations, discontent about school, teacher's partiality to students, and sexual curiosity. The female children have a significantly positive correlation of obesity index (%) or body fat(%) with stress scores from appearance, quarrels of parents, and inferiority complex to brothers or sisters. These results suggested that counselling and education about not only balanced diet but also the strategies for actively coping with stress are needed to prevent and treat childhood obesity.
Objectives: This study was to examine the associations between obesity level and major chronic diseases in older population in Korea, using different obesity indicators. Methods: Data was from the 2008 KloSA Biomarker pilot, a nationwide sample of 514 non-institutionalized subjects (age $63.6{\pm}9.8$ years; women 57.2%). Anthropometric information was collected by home visiting nurses. Portable bioimpedence devices(Omran HBF359) were used for measuring fat mass. Obesity cut-offs used the Asian criteria of $BMI{\geq}25$, $WC{\geq}90/85cm$, and $fat%{\geq}25/35$ for men and women. Chronic disease prevalence was defined by physician-diagnosed history of 8 specified diseases. Results: Prevalence of chronic diseases significantly increased with increment of obesity level by BMI, WC and fat %. Odds ratios of acquiring chronic diseases remained significant in the obese group (BMI OR 2.76, 95%CI 1.82-4.19; WC OR 2.73, 95%CI 1.81-4.11; Fat OR 1.87 95%CI 1.26-2.78), after adjusting for age, sex, marital status, education, work participation, household income, smoking, drinking, and exercise. Conclusions: Obesity measured by all three indicators, BMI, WC, and fat mass cannot be disregarded, accentuating the significant effect on increases in disease risks among older population. BMI and WC measure appeared better to assess the risks of chronic diseases.
