This study investigated and compared the daily activities and energy expenditure of normally-weighted and obese elementary school children. The participants were 115 boys and 115 girls (6th grade) at ten elementary schools in Busan. Time spent on each activity was evaluated using the twenty-four hour recall method. 1) The general characteristics of the normally-weighted and obese children did not differ, although the normally-weighted children exercised and used stairs more than the obese children.2) Among their classified activities, the children spent most of their time resting, study, leisure, physiology and hygiene, commuting, and housework in that decreasing order. Normally-weighted children spent less time tying down and in conversation with family and friends than obese ones. 3) The children's average activity factors were 1.47 - 1.50. The normally-weighted children's rest energy expenditure (REE) (1391.4 kcal,1264.7 kcal) was less than that of the obese children (1711.4 kcal. 1461.0 kcal) . The normally-weighted children's daily energy expenditure was less than that of the obese, but energy expenditure per body weight was less in obese children than in the normally-weighted. In conclusion, sedentary activities and energy expenditure per body weight was less in the obese compared to the normally-weighted children. Programs to help children perceive and practice desirable physical activities should be suggested for prevention of obesity in children. (Korean J Nutrition 38(10): 847$\sim$855,2005)
The dietary habits of middle-aged obese, overweight and normal subjects were evaluated for the purpose of providing the background information of the degenerative disease control. A survey was conducted with 293 subjects (121 males and 172 females) between the ages 40-64 and they were divided into three groups of normal (BMI 18.5-22.9), overweight (BMI 23-24.9) and obese ($BMI\geq25$) based on the criteria of Korean Obesity Association (2000). The mean age of the subjects was $52.0\pm7.3(male)\;and\;51.9\pm6.9$ (female). Socioeconomic levels of subjects belong to the mid-upper class, since 71.9% of the males and 39.5% of the females received above a college education. More than 40% (44.6%) of males and 22.1% of females were obese, and educational background did not affect the obesity rate in males, whereas in females those who received lower education had a higher rate of obesity (p < 0.001). The subjects had a similar degree of drinking to the national average value. but had a lower degree of smoking. The obese group had the higher rate of drinking (p < 0.01) and smoking (p < 0.01). The annual increase in weight, more than 4 kg, was 8.8% for normal group and 30.9% for obese group. However, there were no differences in the mean annual increase in weight among the three groups. In females there were greater tendencies of weight changes in obese group (p < 0.05). About 44.9% of subjects responded that they were exercising regularly, and the obese group appeared to put into practice less than the other groups and to use more strenuous exercise. There was the greater rate of skipping dinner in the obese female group (p < 0.05). The unbalanced dietary pattern was found more with normal group than the other groups (p < 0.01). The food consumption frequency by food groups was not different among the groups. The obese group consumed less frequently meats, vegetables and fruits and had higher frequency in fish, legumes and their products, instant or fast food. In all subjects the higher rate of obesity was found with males than females and with those of heavier smoking and drinking, and in females the higher rate of obesity was found with lower education levels, skipping meals and having an unbalanced diet. In middle-aged subjects of this study with higher educational and socioeconomic background factors contributing to the effects of obesity may include smoking, drinking, educational background, skipping meals or unbalanced dietary pattern. The predictable characteristics for the development of obesity can be defined as sudden fluctuation of weights, exercise regularity and intakes of vegetables and fruits.
This study was carried out to find out differences about meal conditions and food preference between non-obese and obese elementary school children. Ten children(non-obese 5 and obese 5) from each of the nationwide 192 schools were surveyed by self-developed questionnaire. Total of 1,767 questionnaires(815 from non-obese and 952 from obese children) were collected and data were analyzed using SPSS 12.0 program. The results of the comparative analysis were summarized as follows. There was not significantly different in height between non-obese $group(151.0{\pm}12.5cm)$ and obese $group(151.2{\pm}12.3cm)$. But BMI was significant difference between non-obese $group(18.0{\pm}2.2cm)$ and obese $group(27.3{\pm}3.2cm)$. Economical status was not significantly different between 2 groups. But educational level of parents and mother’ job were significant differences between 2 groups. Only 2/3 of the subjects reported to have breakfast at regular basas, regularity of having breakfast was not significantly different between 2 groups. Also regularity of having lunch during vacation was not significantly different between 2 groups. But Reasons of skipping breakfast and lunch were significantly different between 2 groups. Regularity of having dinner, reasons of skipping dinner, intake amount in dinner, and frequency of having snacks were significantly different between 2 groups. But the time required for lunch and dinner were under 20 minutes of 60-80% of the subjects, and were not significantly different between 2 groups. Non-obese group have liked fast foods, fruits & juices, sweets, and cakes & cookies than obese group. Obese group have liked meat & meat products and ramyeon, but they have not eaten those foods frequently because of anxiety about being more fatty. These findings suggested that nutrition education programs include different strategy according to obesity and obese prevention program is needed for non-obese school children.
Recently obesity which had not been at issue very much before comes to the fore as an important health problem. But women frequently attempt excessive weight controls not to cure obesity but to fit false norms of women's appearances. Both these trends and tendencies of perceiving themselves to be fatter than what thay are work as a kind of stressor which impose psychological burden on most women, and finally threaten their mental health. In this point, the purpose of this study was to analize the factors having an effect on women's weight-related stress. This study included a survey and obese level measurement of a systematic random samples of 431 E. University senior students for 17 days(from 13 May 1996 to 29 May 1996). As results, obese level, especially the subject's evaluation for her obese level, history of weight control, and strong weigh control beliefs that the success depends on herself influenced stress.
This study was conducted to determine the eating habits of obese elementary school students residing in Iksan city, in June 2006 using 1167 participants(obese: 233, normal weight: 934). The results are summarized as follows. The average age was 12 years-old in both the obese and normal weight groups. The average BMI, ideal body weight and obesity index in the obese and normal weight groups were $24.8kg/m^2$, 39.8 kg, and 32.5% and $18.2kg/m^2$, 37.7 kg and -1.4%, respectively. Regarding the number of subject who acknowledged their physical build, the obese group was highest(88.9%) in stating obese or extremely obese, while the normal group was highest(71.5%) in stating they were normal weight. For the frequency of eating breakfast, the obese group the results were: "eating it everyday"(69.1%) and $"3{\sim}4\;times/week"$ (13.7%), while in the normal weight group, the highest response was "eating it everyday"(75%) and the lowest response was "never eat it"(4.1%). In terms of having breakfast with someone, there were slight differences for eating alone between the obese group(17.4%) and normal group(12.4%) and also between the obese group(19.6%) and normal group (39.6%) for eating with parents. There were considerable gaps in the association of eating habits with weight such as having irregular meals in the obese group(52.4%) and having regular meals in the normal group(61.1%). The frequency of having snacks was different by the rate of obesity, where 65.9% of the obese group, and 57.8% of the normal group had snacks more than once. There were significant differences in the practice of controlling intake with the obese group at 77.3% and the normal group at 36.3%. There were high numbers regarding eating more than average in stressful times for both the obese group(10.3%) and normal group(7.7%). The results of this study show the prevalence of obesity in Iksan, and proper nutrition education is currently needed. Moreover, the greater the level of obesity, the higher the frequency of skipping breakfast, eating alone, and eating irregular meals, and the more experience in attempting to control weight. To resolve the problems triggered by inappropriate food habits, proper food and eating methods to control weight should be included in nutrition education programs for elementary students.
Purpose: The purpose of this study was to understand sleep circadian rhythm and sleep quality between normal-weight and obese group according to Body Mass Index to develop education and nursing intervention programs for the obese. Methods: This study involved 186 subjects who visited at S hospital obesity clinic, K province. They were divided into 2 groups: normal-weight group 91 and obese group 95. Data were collected from October 18th to November 12th in 2013. Data were analyzed with frequency, percentage, ${\chi}^2$-test, Mann-Whitney U test, ANCOVA, t-test and ANOVA with using SPSS version 20.0. Results: The results showed that morning type 1.1%, middle type 91.2% and evening type 7.7% of sleep circadian rhythm in normal-weight group and middle type 92.6% and evening type 7.4% of sleep circadian rhythm in obese group. There were statistically significant results on sleep quality with covariance sex and stress, sleep duration, habitual sleep efficiency and sleep disturbance between normal-weight and obese group. There were statistically significant results on sleep quality, sleep duration, habitual sleep efficiency and sleep disturbance in middle type of sleep circadian rhythm between normal-weight and obese group. Conclusion: Therefore, it is necessary to consider subject's sleep pattern to develop education and nursing intervention programs for the obese.
The purpose of this study was to investigate the nutrient intakes, nutritional knowledge, food habits, and lifestyle behaviors of moderately or severely obese children living in the Kyonggi-do area. The subjects in this study were 37 obese children with an obesity index higher than 130% in the forth to sixth grades of elementary school. Anthropometric measurements, 24-hour recall of dietary intakes, and a survey on nutritional knowledge, food habits, and lifestyles behavior were conducted in the 37 obese children (25 boys and 12 girls). The average age, body weight, BMI, and R$\ddot{o}$hrer Index were 12.4 years, 68.6 kg, $29.6kg/m^2$, and 194.9 in boys and 12.7 years, 65.7 kg, $29.8kg/m^2$, and 201.8 in girls, respectively. The percentage of correct answers on nutritional knowledge and nutritional attitude score/max score were 85.8% and 23.0/50 in boys and 87.0% and 17.5/50 in girls, respectively. Except for calcium (85.3%) in girls and calcium (62.7%) and folic acid (83.3%) in boys, the average daily nutrient intakes percentages of nutrients were greater than the DRIs values (107.9~327.3% in boys and 103.0~416.0% in girls). This study showed the existence of some problems associated with obesity, such as higher frequency of skipping breakfast, irregular meal times, unbalanced diet, lack of intake of some nutrients, low nutritional attitude, lack of physical activity, and time management in obese children. These results suggest that a systematic education program including nutritional education on balanced diet, good eating habits and behaviors, and importance of eating breakfast and meal regularity must be emphasized to improve nutrient intakes and food habits in obese children. Obese children also require a more concentrated program that includes physical activity, weight reduction, and weight maintenance strategies to improve their life habits.
Purpose: The purpose of this study was to compare metabolic syndrome (MS) risk factor prevalence by obesity and age in middle-aged women. Method: Two hundred and fifty-one subjects were recruited from the health promotion center of a tertiary care hospital in an urban city. MS was defined by the third report of the national cholesterol education program (NCEP) expert panel on detection, evaluation, and treatment of high blood cholesterol in adults(Adult Treatment Panel III)(ATP III), and obesity was determined by body mass $index(BMI){\geq}25kg/m^2$. Results: The mean blood pressure, fasting glucose, total cholesterol, and triglyceride were significantly higher in the obese group than in the non-obese group. The prevalence of MS, hypertension, and impaired fasting glucose were significantly higher in the obese group than in the non-obese group. In the forties, blood pressure was significantly higher in the obese group than in the non-obese group. In the fifties, body fat, systolic blood pressure, fasting glucose, total cholesterol, and triglyceride were significantly higher in the obese group than in the non-obese group. Conclusions: These results show that the nurse should focus on the obese fifty year old female patients for improvement of the MS risk factors.
This study was carried out to compare the hair mineral status of obese, over-weighted and non-obese individuals, to gather basic data for customizing menu development and to create an education manual for the obese persons. Food preferences or various disease states could be suggested by different mineral patterns in TMA(tissue mineral analysis). The results indicated that Zn status was considerably lower in the obese individuals than in the non-obese(p<0.001) whereas hair Na(p<0.0001), K(p<0.01) and Fe(p<0.05) were at significantly higher levels in the obese individuals. The ratio of Ca/K(p<0.001) was significantly lower in the obese than in the non-obese. But the levels of hair toxic minerals such as Sb, As, Hb, Al et al. were not differ according to BMI groups. The obtained data demonstrate the changes of hair mineral content in both overweight and obese individuals thus suggesting metabolic mineral disturbance in those groups.

This study was designed to contribute to the right development of children's physical strength and growth by making a comparative analysis of 6 graders' physical strength with the help of the 6 events of physical strength tests according to sex and trying to work out some relationship between obese children and normal ones. With this in mind, the subjects were 400 elementary students, obese and normal, who reside in Seoul. The results were made by means of the average records and standard deviation test of 6-event physical strength tests per sex and group. The conclusions were as follows; 1. The normal children's average score was better than those of their counterparts, showing a significant difference in the 6-event of physical strength tests. 2. There was a little difference per sex. And there was a significant static interrelations in 4 events except a 100 m race and a standing broad jump when the subjects do well in the two afore-mentioned events. All the other groups minus female normal one show a low interrelations in such events as a 100 m race, a chin-up, and hanging down from the horizontal bar. 3. The obese group was inferior to the normal one regardless of sex. In terms of the physical interrelations, there was no difference among the three groups minus the female normal one.
