Objectives: This study was performed to investigate trends of smoking characteristics and to identify the relationship between smoking characteristics and obesity among military personnel in Korea. Methods: The study participants were 50,680 military personnel who participated smoking cessation clinic from January in 2009 to December in 2017(excluded in 2011). Obesity was defined as body mass index${\geq}25kg/m2$. Smoking characteristics was included cigarettes of smoked per day, age of initial smoking, smoking duration, and nicotine dependence. Binominal logistic regression analysis was performed to confirm the relationship of smoking and obesity among military personnel. Results: The prevalence of obesity of study subjects was 20.4%. The military personnel were more likely to be obese if they who smoked more than 20 cigarettes per day(adjusted OR 2.271, CI 2.027-2.545), who smoked for more than 10 years(adjusted OR 2.046, CI 1.820-2.299), and who smoked their initial smoking at later than 20 years(adjusted OR 1.357, CI 1.223-1.493). Conclusions: Obesity is closely related to cigarettes of smoked per day, age of initial smoking and smoking duration among military personnel. Thus, intervention included both smoking cessation and weight control are necessary for smokers with obese who are interested in losing weight among military personnel.

The purpose of this research was to investigate the mediation effect of bullying on the associations between children's overweight and obesity problem and mental health problems. Data from a subsample of 2,306 adolescents, who participated in the "child-youth synthesize survey" was utilized. The measurement and structural models were estimated using structural equation modeling. Partial and full mediation models were compared, and X2 difference test was conducted between the two models. The study results show that children's overweight and obesity problem have a direct effect on mental health problems. In addition, bullying was found to mediate the association between children's overweight and obesity problem and mental health problems. The analytic results confirmed that the model fit for the full mediation model was better than the partial mediation model when examining the mediating effect of bullying on the relations between children's overweight and obesity problem and mental health problems. Efforts to prevent mental health problems may require interventions for children's with overweight and obesity problems as well as inventions for reducing bullying in general.

BACKGROUD/OBJECTIVES: Obesity is globally a major public health issue. Evidence suggests that elevated ferritin levels are associated with obesity, dyslipidemia, insulin resistance, and metabolic syndrome. This study was undertaken to examine the relationship between the serum ferritin level and depression in Korean male adults with respect to classification of the prevailing obesity. SUBJECTS/METHODS: This was a case-control study; subjects were classified into obese group (${\geq}25.0kg/m^2$, 28 subjects) and normal group ($18.5-22.9kg/m^2$, 27 subjects). A survey was conducted to assess the depression levels as per the guidelines suggested by the Center program for Epidemiological Studies-Depression (CES-D). Blood was collected from each group for assessing biomarkers, and isolated plasma was evaluated for fasting glucose, insulin, quantitative insulin sensitivity check index, and ferritin levels. Data were analyzed, and groups were compared with respect to Body Mass Index (BMI), depression scale and biomarkers. RESULTS: The average depression score of the obesity group was 16.86, which was higher than the normal group (12.56). Subjects scoring more than 16 points comprised 53.6% of the population in the obese group, which was more than double that in the normal group, as assessed by the CES-D program. Furthermore, the serum ferritin level of the obesity group was 207.12 ng/mL, which was higher than that of the normal group (132.66 ng/mL). Lastly, the BMI appeared to be significantly correlated with both depression (r = 0.320, P = 0.017) and elevated ferritin levels (r = 0.352, P = 0.008). CONCLUSION: This study provides evidence of existing correlation between ferritin and depression with obesity.

Purpose : Obesity is a major public health burden in developed countries and a well-known risk factor for cardiovascular disease. Short sleep duration is associated with obesity, as well as diabetes, heart disease and death. In modern society, habitual sleep restrictions seem unavoidable due to social obligations and work schedules along with a tendency toward decreased sleep time. Therefore, the purpose of this study is to examine the effect of differences in sleep time between weekdays and weekends on body mass index (BMI). Methods : This study involved 4,234 Korean adults aged 20 to 64 years based on data obtained from the 7th national health and nutrition examination survey (2016). All subjects were classified into the weekend catch-up sleep group (weekend CUS group). and the non catch-up sleep group (non-CUS group). Results : The longer the average sleep time, the lower was the BMI, and the larger the difference in sleep time between weekdays and weekends, the lower was the BMI. Compared with those with an average sleep time of 8 hours or more, obesity was 1.6-fold higher when the average sleep time was less than 6 hours, and 1.2-fold higher in the case of sleep time of 7 hours or more and less than 8 hours. When the difference in sleep time between weekdays and weekends was 0 or less, more than 0 hours but less than 1 hour, and more than 1 hour and less than 2 hours, the risk of obesity was 1.2-fold, 1.1-fold and 1.1-fold higher, respectively, compared with the risk associated with a sleep time difference of 2 hours or greater between weekdays and weekends. However, the difference was not statistically significant. Conclusion : Short sleep duration is positively associated with obesity. In addition, weekend catch-up sleep affects BMI.

Objectives: The study aim was to analyze the regional differences in dietary protein intake and protein sources of Korean older adults and their association with metabolic syndrome. Methods: Study participants were 1,721 older adults aged 65 and over who participated in 2016-2019 Korea National Health and Nutrition Examination Survey. Using 24-hour recall dietary intake data, protein intake and their food sources were examined. The association between protein intake and metabolic syndrome, obesity, and abdominal obesity were analyzed by multiple logistic regression. Results: Total protein and animal protein intakes were higher in urban area (60.0 g, 24.4 g, respectively) than in rural area (54.6 g, 19.6 g, respectively). With increase of protein intake level, animal to total protein proportion was increased in both areas. Total protein and plant protein intake was negatively associated with the risk of obesity, abdominal obesity in both areas. Animal protein intake was negatively associated with the risk of obesity in both areas, and with abdominal obesity only in urban area. In urban area, plant protein intake was also negatively associated with the risks of metabolic syndrome, elevated triglyceride, and reduced high density lipoprotein-cholesterol. In urban area, the risk of metabolic syndrome was decreased when their protein intake was more than 0.91 g/kg and was lowest when their protein intake was more than 1.5 g/kg (P for trend < 0.001). Conclusions: Korean older adults showed inadequate protein intake and those in rural area showed lower animal protein intake than in urban area. The risk of obesity and metabolic syndrome was decreased with the increase of protein intake level. These findings may help develop effective nutrition support strategy for older adults to reduce regional health disparity.

This study aimed to analyze the association between hyperuricemia and hs-CRP in adults with hypercholesterolemia and abdominal obesity, utilizing data from the 7th Korea National Health and Nutrition Examination Survey. The subjects were classified into fourgroups based on hypercholesterolemia and abdominal obesity, and binary logistic regression analysis was conducted. The association between hyperuricemia and hs-CRP wasevident in the abdominal obesity group, with an OR 2.22 (95% CI 2.070-2.395). In thegroup with both conditions, the OR was 2.31 (95% CI 2.032-2.626). Stratified by gender, both conditions showed a higher OR in males 2.29 (95% CI 1.911-2.748), while in females, the abdominal obesity group exhibited a higher OR of 2.44 (95% CI 2.146-2.775), indicating a gender-specific difference. In conclusion, hyperuricemia and hs-CRP in adults with hypercholesterolemia and abdominal obesity demonstrated a significant association, suggesting their role as predictive factors for inflammatory responses.

The purpose of this study was to determine the mediating effect of perceived stress in the influence of obesity awareness on health behavior, and to verify the moderating effect of nationality between Koreans and Chinese in the influence of obesity awareness on health behavior through perceived stress. Data were collected from August 26 to October 11, 2019, through in-person questionnaire surveys administered to 140 adult participants from a university and general hospital in Seoul, South Korea and 140 adult participants from a university and general hospital in Shenyang, China. Study results revealed that, the obesity awareness of participants had a significant effect on their health behavior, and the mediating effect of perceived stress was significant in the influence of obesity awareness on health behavior. According to nationality, a significant difference was shown between Koreans and Chines in the way obesity awareness directly affected health behavior. However, the indirect effect of obesity awareness on health behavior through perceived stress was not controlled. These results showed that the obesity awareness of Chinese adults had a greater effect on their health behavior than Koreans. In addition, obesity awareness increased perceived stress and decreased positive health behavior in both Koreans and Chinese adults. Therefore, managing the stress caused by obesity is an important factor in increasing positive health behavior.

The purpose of this study is to provide basic data for the oral health and obesity management of adults by grasping the relationship between obesity and oral health. Among the patients who visited the dental clinic, 229 patients who agreed to fill out questionnaires were analyzed by self - filling questionnaire. Body mass index and waist circumference were used for the study of obesity. Body mass index and poor periodontal health status were significantly higher(33.3%) and abdominal obesity and poor periodontal health status were 10.9%.Abdominal obesity was significantly higher(28.6%) in the group with less than 20 teeth. Body mass index and abdominal obesity were higher in body pain, psychological discomfort, physical abilities, psychological abilities, social disadvantage, and oral health than in normal subjects. As a result of correlation analysis with obesity index, it was found that the more period of obesity, the more periodontal disease and mucosal state related symptoms appeared(p<0.05). Therefore, in order to solve health problems such as obesity, it is necessary to recognize the importance of oral health and to make efforts to induce positive oral health behavior.

The objectives of this research is to examine: 1) how the rates of adolescents' BMI change over time in terms of the state level; and 2) development difference in the state level of BMI in terms of children's obesogenic behaviors from 1999 to 2011. Data were drawn from the 1999-2011 Youth Risk Behavior Survey in the United States (N=260, 293, grades 9-12, and 27 states). Ordinary least squares regression and hierarchical linear modeling were utilized to capture a longitudinal time effect of school-aged adolescents' obesity rates across the states, controlling for demographics and nutrition- and physical activity-related behaviors. The state's level of children's BMI percentile was significantly associated with longitudinal time. Longitudinal time effect across the states appears to play an important factor associated with children's decrease of BMI percentile. Therefore the states' implementation of physical activity and nutritional policies seems to be effective for preventing and reducing childhood obesity during last decade. More attention should focus on enforcing the policy and overcoming current barriers in order to minimize children's obesogenic factor.
