The purpose of this study was to provide fundamental materials for improving school health promotion programs by investigating the relationships between the change in obesity rate and risk factors of metabolic syndrome among middle school students in Ulsan. We analyzed the routine health check-up data in 58,298 2nd-year middle school students in Ulsan, which conducted by the Planned Population Federation of Korea from 2007 to 2011. The overall and girls obesity rates gradually decreased throughout the first four years but increased again in 2011. The boys obesity rates were highest in 2008 and lowest in 2010. Throughout the research years, the incidence rates of over-weight and obesity were statistically significantly higher in boys compared to girls(P<0.05). Prevalence rates of the metabolic syndrome, assessed with the modified Cook criteria except high blood pressure, were 0.58%, 0%, 0.01%, 0.31% and 4.53%, respectively in total, low, normal, over-weight, and obese groups. It indicates that the prevalence of metabolic syndrome is increasing and directly related to the obesity rate among adolescents. Hypertriglyceridemia was the most common component (36.58%) of the metabolic syndrome among the middles school students followed by low HDL cholesterol (6.47%), abdominal obesity (3.72%), and high blood sugar (0.47%). Prevalence of the various components of the metabolic syndrome were significantly higher in the obese group compared to other groups. In this study we observed the decrease in obesity rates between 2007 and 2010, and developing obesity prevention programs is essential in order to maintain the trend. Additional study should be necessary to find the cause of increase of obesity rate in 2011 and so to create more effective school health promotion programmes.

Diabetes Mellitus (DM) is well known for increasing morbidity and mortality, especially related to their complications. The purpose of this study was to investigate the factors affecting the prevalence rate of DM and provide a fundamental material to develop an intervention strategy to reduce the prevalence rate of DM. The study subjects were adults aged over 19 on the basis of the primitive data of "The Fifth Korean National Health and Nutrition Examination Survey, 2012". Therefore, the data of 5995 participants were analyzed. For data process, the complex sample analysis module of SPSS 18.0 program was employed to add weighting before analysis. According to the analysis, the prevalence rate of DM of the study subjects was 10.5%. Regarding the odds ratio of DM prevalence, the subjects who graduated from middle school had the odds ratio 2.51 times higher than those who graduated from college and more; those in subjective bad health condition 4.77 times higher than those in subjective good health condition; those in obesity 1.44 times higher; those with high blood pressure 2.57 times higher; those with hyperlipidemia 2.63 times higher; those who fail to control their weight 1.31 times higher; those going on a diet 2.75 times higher. This study revealed that a level of education, perceived health status, obesity, high blood pressure, hyperlipidemia, weight control, and dietary therapy were the predictable variables of the prevalence rate of DM, and thereby suggested the nursing direction and research direction to reduce the prevalence rate of DM.

Purpose : The aim of this study was to evaluate whether breast milk feeding at infancy has the effect of a programming agent preventing school-age obesity, or whether formula milk feeding is the cause of elementary school-age obesity. Methods : We randomly selected 4 elementary school in Masan and Changwon city. We calculated the BMI and obesity degree from height and weight data on the school record of 1,275 children of first and second grade. The parents of 1,275 children were asked to a questionnaire about their birth history and feeding modality during infancy. Based on these data, we categorized them into 4- different groups : breast fed for less than 2 months; breast fed for 2-6 months; breast fed more than 6 months; mixed fed. We compared the mean BMI, obesity degree and prevalence rates of obesity of each groups. Results : There was no statistical difference on the prevalence rates of overweight and obesity, which was defined by BMI, according to the duration of breast feeding. The same was true for mild obesity and moderate obesity, which was defined by obesity degree. The mean BMIs and the mean obesity degree were not different among different feeding types. Conclusion : There seems to be no protective effect of breast feeding during infancy on reducing the prevalence rates of overweight and obesity. However, even wider and larger studies considering confounding factor might be needed to reach a definite conclusion in the future.

Background: The aim of this study was to examine the association between physical activity and periodontitis in the Korean population. Methods: This study utilized data from 9,191 participants of the Korea National Health and Nutrition Examination Survey. Periodontitis was defined as a CPI score of 3 or 4. Physical activity was assessed by the trained interviewer using the International Physical Activity Questionnaire-Short Form (IPAQ-SF). IPAQ-SF is composed of vigorous physical activity, moderate physical activity, and walking activity. Multivariable logistic regression analyses and stratified analyses by obesity were performed. All analyses were conducted separately for males and females. Results: Females who engaged in vigorous and moderate physical activity had a 28% (OR = 0.72, 95% CI = 0.54 - 0.95) and 34% (OR = 0.66, 95% CI = 0.44 - 0.98) lower risk of periodontitis, respectively. In obese females, moderate physical activity in obese had a 65% lower risk of periodontitis (OR = 0.35, 95% CI = 0.18 - 0.67). Conclusions: Our findings suggest that moderate-intensity physical activity was inversely associated with a lower risk of periodontitis. In obese females, moderate physical activity had an independent inverse association with periodontitis.

Purposes: This study aimed to investigate the differences in the prevalence of obesity according to sex and age and self-rated health in adults with metabolic syndrome according to sex, age, and the presence or absence of metabolic syndrome. Methods: The study subjects were 5,674 adults, who completed all three components of the KNHANES VI-2. The subjects were categorized, using life transition periods, into young adults, middle-aged adults, and older adults. Research methods were selected based on the research objectives of the KNHANES VI-2. IBM SPSS 23.0 was used for complex samples cross-tabulation and a complex samples general linear model analysis. Results: Obesity was prevalent in 77.2% of young male adults, 66.2% of middle-aged male, and 52.3% of older male adults with metabolic syndrome, whereas it was prevalent in 72.4% of young female adults, 73.9% of middle-aged female adults, and 64.6% of older female adults with metabolic syndrome. Men had higher self-rated health than women. As age increased, self-rated health status decreased. Those with metabolic syndrome had lower self-rated health status than those without metabolic syndrome. Conclusion: The prevalence of obesity was found to be high in those with metabolic syndrome. This study found that based on sex, men had the highest self-rated health status, and based on age, young adults had the highest self-rated health status, whereas those with metabolic syndrome had low self-rated health status.

Purpose : The objective of this study was to provide current estimates of the prevalence and examine trends of overweight and obesity in children and adolescents. Methods : Height and weight measurements from 183,159 (112,974 in 1997, 70,185 in 2005) children and adolescents aged 2 to 18 years were obtained via the 1997 and 2005 National Growth Survey. Obesity among children and adolescents was defined as being at or above the 95th percentile of the gender-specific body mass index (BMI) for age in the 2007 Korean National Growth Charts or a BMI of 25 or higher; overweight was defined as being at or above the 85th percentile to less than the 95th percentile BMI. Results : In 2005, 9.7% (11.3% for boys, 8.0% for girls) of South Korean children and adolescents were obese; 19.0% (19.7% for boys, 18.2% for girls) were overweight or obese. The overall prevalence of obesity increased from 5.8% in 1997 to 9.7% in 2005 (from 6.1% in 1997 to 11.3% in 2005 for boys and from 5.5% in 1997 to 8.0% in 2005 for girls); the increasing trend was most evident in boys, especially those aged 13-18 years. Conclusion : The prevalence of obesity among children and adolescents increased significantly during the eight-year period from 1997 to 2005. This study suggests that we need to make a priority of developing strategies to control obesity in children and adolescents; the potential health effects of increases in obesity are of considerable public health importance.

Leptin, as an adipocyte-derived hormone, is an important regulator of food intake and energy expenditure. In the cross-sectional study, leptin was shown to be positively related to body adiposity and metabolic disorders in adults. However, there were very few studies which reported the leptin as a predictor of weight gain over time. We examined whether serum leptin can be used as an indicator of the present and 1-year past weight status in very young children. First grade students from elementary schools in Gwacheon City were enrolled in the study since 2005. The study subjects(total 375 students; 195 boys and 180 girls) participated in the investigation of both 2005 and 2006. Physical examinations including height, weight, waist circumference were done. To examine the prevalence of obesity, obesity index was used. Serum leptin was measured, and their nutritional status was also evaluated based on 3-Day dietary records. Serum leptin levels were strongly positively related with the value of the present BMI and with the value of the BMI one year before. We found no association with leptin levels and amount of energy intake and macronutrient intake in this children population. Children were divided into three groups according to leptin tertiles. The highest leptin tertile group showed highest prevalence of obesity in year 2006 as well as in year 2005. Serum leptin levels can reflect the weight status now and as well as 1-year before. Possibly serum leptin levels can predict the weight gain of year later. Without an action against the obesity on children with high leptin level, those children would maintain the excess adiposity growth and progress into the obesity-related metabolic disorders. Further studies are needed to predict the obesity as early as possible and preventive system then after.

The purpose of this study was to investigate the relationship between oral health behaviors and periodontal diseases in adult obese people. Using the original data of the second phase of the 6th National Health and Nutrition Survey, the final 4381 adults were extracted. We analyzed frequency and technical statistics and chi - square test and multiple logistic regression analysis using SPSS statistical program to confirm the association between body mass index, number of brushing, drinking, smoking and oral health status and behavior. As a result, the prevalence of periodontal disease decreased as the number of toothbrushing increased, and the prevalence of periodontal disease increased as the body mass index increased. Through this study, obesity, a global health issue, should be more concerned with oral care and develop oral health management programs.
