Objective : To get a better understanding of obesity and etiological factors of obesity among school children. Methods : We have conducted a questionnaire survey of 4542 (2395male and 2147female) age from 7-15 in Shanghai School District to study their 24h nutrition intakes ; we have asked all our survey participating students to take a physical exam and body mass index measurement to determine the morbidity of obesity. Common statistic method was used in analyzing the data. Results : The result shows an over all morbidity (boys and girls) of $12.3\%$ among the students we have studied. Our research shows that boys have a higher rate of morbidity of obesity $17.1\%$ vs. $7.0\%$ for girls. The morbidity for boys starts under age 10, reaches the peak at age 10 ($24.3\%$), then declines after age 11 ; as for girls the morbidity starts at under age 9, reaches the peak at 9, and then declines after 10. Our study also indicates that the daily nutrition intake of protein, fat and carbohydrate by the students have satisfied Chinese Dietary Reference Intakes (DRIs), while the daily intakes of calcium, iron, zinc, and vitamin C are below the $80\%$ of the DRIs suggested value. For students who are obese, our study shows that their average daily intakes of calories and protein have reached $90\%$ of the suggested value by the RNI while the intakes of calcium, iron, and zinc are far below standards. Furthermore, our research shows that the obese students usually intake more calories, proteins and vitamin $B_1$, but less for iron and calcium compared to the normal students. Some other factors such as the education and occupation of the parents, especially the mother, the family history of obesity and the eating habits are important factors that should be closely watched. Conclusion : The morbidity of obesity among boys is higher than girls. Obesity is closely related to the family history, the diet habits and the life styles.

The purpose of this study was to provide information on obesity assessment for Koreans. Among total of 1012 research papers enlisted in the Korean J Community Nutrition form 1996 to 2011, 248 articles were examined in which subjects were divided into more than 2 groups by obesity rate. About the method of anthropometric data collection, more than half of the research papers examined 52.5% and 28.7% of studies utilized the directly measured data and self-described data, respectively. About the utilization of obesity assessment methods, indirect methods of weight-height index (BMI, BMI percentile, and R$\ddot{o}$hrer index) and PIBW (WLR, Broca index, and KDA) were 62.4% and 23.2%, respectably, and the direct method of percent body fat assessment was only 9.3%. The most frequently utilized methods were WLR in under primary and primary school children, and BMI in the middle and high school students and in adults. For primary school students, WLR was the most frequently utilized method up to 2007, but it changed to BMI percentile afterward. Broca Index was no longer utilized since 2008. There were no articles utilizing BMI percentile and R$\ddot{o}$hrer index for obesity assessment in adults. Criteria for obesity assessment were not consistent among research papers: for example, % body fat, 19~40%; BMI, 20~30; BMI percentile, 85th or 95th. In the case of PIBW, 120% of ideal weight was the most frequently utilized criterion for obesity. Based on these findings, we suggest that proper methods and criteria of obesity assessment for each age group should be determined and proclaimed.

The purpose of this study is to determine the prevalence of obesity and to examine the eating habits of elementary school students in Iksan dity. The study was carried out on 292 students(male: 151, female : 141)in May of 1997. The average height and weight of the subjects were 141 cm and 37kg in males and 142 cm and 36kg in females, which were similar to the average of Chonbuk. A Weight/Length Index(WLI), Broca Index, Rohrer Index(RI), Body Mass Index(BMI) and Waist Hip Ratio(WHR) were used as an obesity index to classify degree of obesity. WLI, Broca Index and RI were proper for judging child obesity and strict judgments were conducted in the order of RI, WLI and Brcoa Index. The subjects were classified as 30.8% underweight, 43.5% normal, 8.2% overweight and 17.5% obese by WLI and there were significant differences between height(p＜0.05) and weight(p＜0.01) according to obesity degree among the four groups. 50.3% of the boys and 55.3% of the girls are regularly, and the main reason they didn＇t ate regularly, and the maim reason they didn＇t eat breakfast(78.4%) was due to lack of time. The frequency of snacks were 1-2 times a week(40.4%), fruits(40.4%) from market and supermarket(68.2%). According to the survey 84.6%, 77.45, 78.1%, 69.9%, 59.9% and 86.6% of subjects didn＇t eat meat, fish, soysauce, instant food, sugar and seaweed respectively. Seaweed, meat, and soysauce showed low preferences. 69.5% and 74.75 of the subjects drink milk and ate kimchi respectively. By analyzing eating habits according to the degree of obesity, the rate of skipping breakfast(p＜0.01), and eating meat or fish(p＜0.05) were high in the overweight and obese groups of girls. In the boys case, the rate of not eating food in sugar(p＜0.05) was high in the obese group. Obese children need to correct their eating habit. This reasserts the importance of nutrition education in children though teachers, parents, and dietitions. The findings of this study may be applied to nutrition education to ensure better physical fitness for children.

Hypertension is a major risk factor for myocardial infarction, stroke, and cardiovascular mortality in adults; its treatment reduces the risk of cardiovascular events. In recent times, attention is being paid to monitoring of blood pressure from childhood to adulthood. Childhood hypertension is associated with hypertension in later life, and early intervention is important. In the Korean socioeconomic background, a rapid increase is observed in the number of obesity cases and the rate of increase in the incidence of obesity is more in childhood. The strong association of high blood pressure with obesity and the marked increase in the incidence of childhood obesity indicate that both hypertension and prehypertension are becoming significant health issues. In this comprehensive review, we acquaint the clinician with the available literature on childhood hypertension to provide recommendations for the diagnosis, evaluation, and treatment of hypertension based on the available evidence and consensus in Korean clinical conditions.

Obesity rates are increasing worldwide, associated with excess acute and chronic disease risk. In most countries, obesity rates among women exceed rates in men, particularly during the post menopausal years. Many factors affect body weight and appetite, including age, metabolic rate, physical activity level, stress, cultural factors, socioeconomic status, health status and health literacy, diet composition, attitudes, and beliefs. Gender affects appetite and body weight indirectly by altering factors contributing to food choice. However, there is emerging evidence that gender affects appetite and body weight directly, altering the physiological control systems regulating appetite. The follicular menstrual cycle phase (estrogen-rich) is associated with relative suppression of appetite. Lower estrogen levels are associated with increased food intake, body weight gain, and altered body fat distribution in humans and animals. This paper reviews the linkages between estrogen and appetite regulation. While relationships among appetite, body weight, and gender-linked hormones are complex, research elucidating these interrelationships could lead to development of gender-specific treatment approaches for obesity and appetite dysregulation.

The prevalence of obesity has been increasing worldwide. Several dietary treatments have been suggested to control weight, and recent guidelines recommend individualizing the composition of macronutrients. Carbohydrates are the most important nutrients in meals, and carbohydrate restriction is a dietary strategy that promotes weight loss. A low-carbohydrate diet is effective for short-term weight loss and can help improve glycated hemoglobin, systolic blood pressure, diastolic blood pressure, and triglyceride levels; however, the long-term effects and safety of this diet remains doubtful. In the short term, there is a risk of gastrointestinal symptoms such as vomiting, diarrhea, constipation, and gastroesophageal reflux, and type 1 diabetes patients are at risk of severe hypoglycemia, while in the long term, it can lead to malnutrition and decreased exercise capacity. Thus, rather than limiting the intake of carbohydrates, it is important to limit the intake of refined grains, sugar, honey, syrup, and sweetened beverages while maintaining the planned carbohydrate intake rate and improving meal quality.

This study was examined 718 workers who had consistent blood pressure results in 2001 and 2002 general health examinations that were held at a work places managed by a health care agency in Seoul. Significant results are found as follows by analysing SPSS 11.0 on the result of self-recorded questionnaires investigated from Mar 1, 2003 to April 30, 2003. 1. A sampled healthy group and a sampled unhealthy group had significant differences in four variables out of possible nineteens that are sex, age, marriage and occupation. The unhealthy group had more males than females, more aged (over 50 years old) than youngers (under 50 years old), more married than singles, more manufacturing workers than non-manufacturing workers. In the case of systolic blood pressure, as the healthy group had 16.52mmHg while that of the other group had 149. 58mmHg, 33.06mmHg of difference between those groups were detected. In the case of diastolic blood pressure, 74.93mmHg of the healthy group and 96.53mmHg of the unhealthy group yielded 21.60mmHg of difference between them. This result implies that a guidance of health care is required to be aware of 20-30mmHg volatility in blood pressure rate or to understand and treat properly own blood pressure. as it is difficult to detect hypertension in early stage due to no initial symptom. According to the result. an establishment of management system of workers, companies and health care agencies is required for consist health care. 2. In terms of risky habits to health, the unhealthy group had more proportion of past smokers, over-twice-a-week drinkers, people with higher obesity rate. However, in terms of excercise, the proportion of regularly exercising people is higher in the unhealthy group while that of non-exercising people is higher in the healthy group. On the other hand. the average grade of health practicing behaviour in two groups are not significantly different as the health group had 3.00 out of possible 6.00 while the other had 3.10. This result means that as workers are not interested in health practicing behaviour. health promoting programmes must be developed in such a way of various method of motivations and incentives. Particularly this implies that distortional objectives of exercises should be readjusted through health guidance. 3. Systolic blood pressure in the healthy group can be explained by sex and the obesity rate while that in the unhealthy group can be explained by subjective health awareness and the obesity. Diastolic blood pressure in the healthy group can be explained by sex and the obesity rate like the former. The obesity rate was significant variable affecting the blood pressure of both groups, and particularly the effect to the unhealthy group was remarkably higher than that to the healthy group. Therefore, this research identified that the health care on the blood pressure of workers is not only limited to hypertension patients, but also extended to all workers. In order for consistent care, an establishment of management system of workers, companies and health care agencies is required.

This study was conducted to evaluate the rate of obesity of 212 women (age 45-60 years) in Seoul and the Kyunggi area through analysis of BMI and the dietary life factors related to obesity using a survey on dietary habits, dietary assessment, and nutrient intake. The height of the underweight group was taller than normal. The height of the obese group was equal to that of the normal group, but the weight was 8.5 kg greater than the normal group. Women in the underweight group consumed meals irregularly, and only 33.4% ate breakfast. Additionally, the rate of overeating was low in the underweight group, and milk, dairy products (yogurt, etc.), fruit, and fruit juice were consumed more than once a day. It was found that 62.1% of the women in the obese group never ate out, and the rate of eating one serving of fruit, drinking one cup of fruit juice, and eating various kinds of foods was high. The average point of women's dietary life was $21.9{\pm}2.9$, and 12.7% of all women responded that their dietary life was good. However, in the obese group, only 6.9% of the women reported that their dietary life was good. Evaluation of snacking habits revealed that the underweight group consumed a high level of carbonated drinks and ice cream, whereas for in the obese group, 24.1% of the women consumed milk and its products and 5.6% regularly consumed fast and fried foods. Evaluation of nutrient intake revealed that the consumption of energy, protein, vitamin A, vitamin $B_1$, $B_2$, $B_6$, niacin, vitamin C, and vitamin E was high in all of the groups, but the intake of folic acid in the underweight group was lower than the required level. Overall, 24.1% of the women in the obese group were found to have metabolic diseases, mostly hypertension (43%). In conclusion, a balanced diet to avoid excessive nutrient intake is needed to prevent obesity.
