Purpose: The purpose of this study is to identify influencing factors of subjective health status perception of obese college students. Methods: We used the data from the 2015 Community Health Survey. The subjects of this study included 951 obese college students. The data were analyzed using t-test, ANOVA and multiple linear regression with SPSS ver. 23. Results: The average score of subjective health status was $3.81{\pm}0.81$. Gender, age, residential area, stress and depression were found to be the influencing factors of subjective health status perception and explained 6.7% of the subjective health status. Conclusion: These findings indicate that effective intervention programs are needed to help obese college students correctly recognize their subjective health status and manage stress and depression.

Objectives: The intention of this study was to find out the impact of mother's body mass index, eating habits, nutrition status and sociodemographic factors on the body mass index of the children. Methods: The study used original data of Korea National Health and Nutrition Examination Survey (2010-2011) and had 957 children in the ages of 1-5 years and 957 mothers of these children, a total 1,914 as subjects. The weights (body mass indexes) of the children, subjects under 5th percentile were classified into a underweight group, 5~84th percentile into a normal weight group, 85-94th percentile into an overweight group and more than 95th percentile into an obesity group based on the 2007 Korean children and adolescents growth chart. Results: We observed that when the body mass index of a mother increased by 1, the possibility that her child would belong to the overweight group increased by 6.5% (95% confidence interval: 1.01~1.13), and the possibility that the child would belong to the obesity group increased by 95% (confidence interval: 1.01~1.18). With regard to the number of deficient nutrients which were ingested according to estimated average requirements (EAR) amid nutrients ingested by the mother increased by 1, the possibility that the child would belong to the obesity group increased by 16.6% (95% confidence interval: 1.01~1.35). In case the birth weight of child increased by 1kg, the odds ratio that the child would belong to the obesity group was 2.022 (95% confidence interval: 1.08~3.77). Conclusions: We conclude that the body mass index, eating habits and nutrition status of the mother had significant effects on the body mass index of the child. Therefore, it is critical to recognize the importance of this observation and provide practical training for eating habits and nutrient intakes in order to achieve healthy growth and prevention of obesity among children.

Objectives: This study examined the differences in dietary life and health related factors, such as drinking behavior, exercise and leisure activities, mental health, and subjective perception for oneself according to obesity in poor urban Peruvian adolescents. Methods: A total of 1,532 Peruvian adolescents were selected from six schools in poor regions using stratified random sampling. The subjects were classified into two groups based on their BMI: 'normal weight group (NW group=980)' or 'overweight and obese group (OWOB group=293)'. The differences in the general characteristics, dietary life, drinking behavior, physical activity and leisure, mental health and subjective perception of oneself in the two groups were compared. ${\chi}^2$ analysis and independent sample t-test were performed using the SPSS program ver. 24. Results: For the total and male students, the frequency of breakfast and dinner were significantly lower in the OWOB group than in the NW group (all p<0.001). For total and female students, the percentage of subjects who received nutrition education was significantly higher in the OWOB group than in the NW group (all p<0.05). For total students, the percentage of subject who exercised more than five days/week was lower in the OWOB group than in the NW group (p<0.05). For the total and female students, the subjective health status was worse in the OWOB group than in the NW group (all p<0.05). The subjective body image was significantly different between the OWOB group and NW group in the total, male and female subjects (all p<0.001). Conclusions: The frequency of meals and exercise, and the subjective perceptions of the health status and body image differed according to obesity in poor urban Peruvian adolescents. Therefore, a school-based intervention program focused on regular meal and exercise, and adequate subjective perceptions for health status and body image need to be developed to prevent adolescent obesity.

The purpose of this study was to examine the blood pressure, serum lipid levels and obesity indices according to smoking status, and the effects of smoking cessation on blood pressure, serum lipid and obesity indices. The 2,230 male workers aged 30-59 years were observed the age, smoking status, SBP, DBP, TC, TG, HDL-C, LDL-C, AI, BMI, body fat rate and waist circumference, from April to July, 2011. As a results, the mean score of SBP, DBP, TC, TG and BMI were significantly higher in smoking group than non-smoking group, but HDL-C were significantly lower in smoking group than non-smoking group, the distribution of hypertension was significantly higher in smoking group than non-smoking group. The abnormal levels of TC, TG and HDL-C were significantly higher in smoking group than non-smoking group, and the distribution of obesity was significantly higher in smoking group than non-smoking group. Age adjusted odds ratio(ORs) was significantly increase in smoking group than non-smoking group: hypertension(3.59 times), hypercholesteremia (1.49 times), hyperlipidemia(1.81 times), low HDL-cholesteremia(1.58 times), high level of atherogenic index(1.27 times). Above results suggested that the smoking related with blood pressure and serum lipid levels.

This study was performed to analyze children's perceptions and practice levels according to gender and obesity status using a dietary life safety index. A national survey was conducted on fifth grade children (n = 2,400), who were selected using three-stage stratified cluster sampling from 16 provinces. The average height was 144.8 cm, and weight was 38.8 kg. The average body mass index was 18.4 kg/$m^2$ and underweight, overweight, and obese children were identified using the 2009 KHNANES cutoff values, which were 5.3%, 10%, and 5.9%, respectively. The perception and practice scores for hand-washing prior to eating were high and the score for willing to buy at a clean store was also high. However, students answered that the hygiene level of food stores near the school was poor. More students skipped breakfast than lunch or dinner. The frequency scores for fruit and vegetables were significantly higher for girls than those for boys. Students had a good understanding of nutrition labeling but did not frequently check the label. Seventy-five percent of the students tried to avoid high calorie foods with low nutritional value, but only 40% had the appropriate knowledge about high calorie foods with low nutritional value. Girls had better dietary life perception and practice levels than those of boys. No differences in perception or practice levels were observed based on obesity status. Nutrition education on the importance of eating breakfast and having accurate knowledge on nutrition labeling and high calorie foods with low nutritional value is needed. Behavior-centered education should be implemented to improve the perceptions and practice level of student's dietary life.

Adolescents grow rapidly and have lots of schoolwork for entrance examination, so good nutrition is very important to them. However, adolescents tend to have a poor dietary behavior including frequent consumption of empty calorie foods and skipping breakfast. In particular, frequency of drinking milk has been low among Korean adolescents, thus their dietary calcium intakes has been low. Undesirable dietary behavior of adolescents is a risk factor for poor nutrition, obesity and chronic disease of them. Milk is a good source for calcium, high quality of protein, vitamin and bioactive compounds including anti-obesity component, thus it has been reported that milk helps improvement of dietary nutrient adequacy and physical growth, increment of bone mineral density, and prevention of obesity and chronic diseases. Therefore, milk consumption of adolescents should be encouraged in order to help their nutritional status, physical growth and health.

Breastfeeding is the best source of nutrition for every infant, and exclusive breastfeeding for 6 months is usually optimal in the common clinical situation. However, inappropriate complementary feeding could lead to a nutrient-deficient status, such as iron deficiency anemia, vitamin D deficiency, and growth faltering. The recent epidemic outbreak of obesity in Korean children emphasizes the need for us to control children's daily sedentary life style and their intakes of high caloric foods in order to prevent obesity. Recent assessment of breastfeeding in Korea has shown that the rate is between 63% and 89%; thus, up-to-dated evidence-based nutritional management of breastfeeding infants to prevent common nutrient deficiencies or excesses should be taught to all clinicians and health care providers.

Hair tissue mineral analysis is widely accepted for assessing essential and toxic elements which can give information about disease, metabolic disorder, nutritional imbalance, drug abuse, environmental exposure and so on. In Oriental Medicine, hair have been used as a diagnostic method which reflects the physiological and pathological status of body, especially kidney system(腎臟) and blood(血) like the quotations from Donguibogam(東醫寶鑑), 'hair belongs to kidney system(髮屬腎)' and 'hair is the remainder of blood(髮者血之餘)' Therefore we have suggested that HTMA have possibility to be utilized for screening and treatment for obesity, growth disorder, general deficiency syndrome(諸虛證), etc. in Oriental Medicine.

Great attentions have been given to obesity in Korea, while the obesity rate has rapidly risen up due to various reasons including the dietary change into the western style. Central and local governments have tried to reduce the rate through various policies and action plans. The governments' activities are frequently criticised to be more coordinated in order to achieve the aim of the activities. The purpose of this study was to develop the coordination strategies through the examination of the acts relating to obesity. At present, activities relating to obesity are based on 25 acts including 'Health Promotion Act', 'Special Act on Children Diet Management' and so on. Six ministries including the Ministry of Health and Welfare and the Ministry of Education, Science and Technology are in charge of these acts. As a result, a number of areas, especially dietary guidance, research, manpower and institutions, seem to overlap. In a short term, Ministerial Council on Obesity should be established in order to enforce the coordination of the policies and activities. In the mid-long term, it is recommended that functions of the Ministries should be more simplified through the reorganization.
