The purpose of this study is to analyze the effects of nutrition education and aerobic exercise program on weight control program of middle aged abdominal obese women. Data for the study were collected from February 14 to April 22, 2005. The study objects were 10 pre-obese women and 10 obese women. The results were as follows; Body weight, body mass index, waist-hip ratio and waist circumference of pre-obese group and obese group were significantly decreased. Nutrition education and aerobic exercise program on body weight and waist circumference were more effective in obese group than in pre-obese group. Total Cholestreol and Creatinine of pre-obese group and Total Cholestreol, Creatinine, U/A and Glucose of obese group were significantly decreased. TG(Triglyceride), BUN(Blood Urea Nitrogen), U/A(Uric Acid), Glucose, SGOT(Serum Glutamic Oxaloacetic Transaminase) and SGPT(Serum Glutamic Pyruvic Transaminase) of prer-obese group and TG, BUN, SGOT and SGPT of obese group were no differences. Obesity management program on Total Cholestreol were more effective in obese group than in pre-obese group. Therefore, it is concluded that the nutrition education and aerobic exercise program on weight control program of middle aged abdominal obese women were more effective in obese group than in pre-obese group.
The purpose of this study is to observe the longitudinal changes in BMI (Body Mass Index) of obese and non-obese 3rd. grade high school students in Seoul for 12 years and to see the trends of overt weight gain in obese adolescents. The results are as follows; 1. The average annual increasing rates of body mass Indices in male students were $1.14kg/m^2$ in obese group and $0.59kg/m^2$ in non-obese group. In female students, the average annual increasing rates of body mass indices were $0.93kg/m^2$ in obese group and $0.53kg/m^2$ in non-obese group. 2. The change rate of BMI for 12 years was significantly higher in obese group than non-obese group. 3. Puberty had less influence on the change rate of BMI in obese group compared to non-obese group. 4. In obese group, 71.8% of the variance in BMI at 17 can be predicted by BMI at 16 years in male students. In female students 44.4% can be predicted by BMI at age 16. 5. Among the 17-year-old obese students, 58.8% of the males and 56.2% of females were found not to have been obese at 7 years of age. 6. Among the 17-year-old obese students, those who were obese at 7 years of age were found to have higher BMI at later ages than those who were in the non-obese group. Obese adolescents were more likely to be obese in their childhood than non-obese group. There was no optimal age for the significant weight gain and the increasing rate of BMI was constantly higher in obese group than in non-obese group. Due to the fact that child obesity in early age contributes to obesity in adolescence, close observation is advised. On the other hand, a large proportion of obese adolescents can be preventable by early interventions, because about 50% of obese adolescents were not obese in early elementary school age.
This study investigates differences in middle school male students' anthropometric variables and dietary habits using BMI (Body Mass Index) classifications. $\chi^2$ -test for frequency and ANOVA test for mean value and duncan value were used to analyze results. Averaged results of three groups of middle school male students' anthropometry including height (normal group 164.4 cm, overweight group 165.0 cm, obese group 167.0 cm), weight (normal group 56.0 kg, overweight group 70.0 kg, obese group 83.2 kg) and waist circumference (normal group 20.7 cm, overweight group 79.8 cm, overweight group 89.6 cm) were resulted. Classification of obese group was based upon 2007 growth charts using BMI criteria. This study indicates the normal weight group boys have over-eating related dietary habits and the obese groups have less calorie dietary habits. They answered oppositely to normal recognition. The obese group reflected dietary problems, such as preferences for sweet fruit rather than normal group males. Dinnertime of the groups were significantly different and obese group's earlier dinnertime can influence on their late night snack eating. Forty precent of obese male group like fruits as late night eating food. Three meal amount of three groups were significantly different, as obese group answered they ate same amount at every meal. It can mean obese group ate more amount of food in every meal. Overweight and obese male students have dietary problem of fast eating and answers of unbalanced eating were higher in normal group. These could mean obese group eats well in every food and fast eating habit could lead a lot of food eating habit. Obese group chooses out-going food of less calorie and frequency of fast food eating was lower than normal group. In result, obese group answered that they have less calorie related dietary habits, it could mean their answers were false or fixed dietary habit. Therefore, more researches should be followed.
The purpose of this survey was to investigate the relationship among obese children, dietary intake and environmental factors. Therefore, this survey compared obese children with normal children on dietary intake and environmental factors. The survey were 110 obese children and 110 normal children whose age, height, and sex were same as the obese children of 21 elementary school in Inchon. The statistical analysis of data was completed using SAS program. The results were summarized as follows : 1) The student's obesity was related to parent's obesity and number of their siblings. There were significant differences between obese groups and normal group for these two factors. 2) Meal time of the obese group showed more irregularity than that of the normal group. Otherwise, the normal group were more "piclity" about special food than the obese group(p<0.05). Also obese children showed unconsious eating while reading or watching TV(p<0.01). The normal group attended physical education class more eagerily the obese group(p<0.001). There was no significant difference between obese children and normal children for learning habits. 3) Obese children shoed higher intake of nutrients compared to normal children. Among all the nutrients, minerals and vitamins showed significant differences. Therefore, further study on obese children and their intake of minerals and vitamin is needed. Also, in order to prevent factors which influence obesity, nutrition education at home as well as school was needed.as needed.
Obesity has been directly associated with the development of hypertension and cardiovascular disease. The purpose of this study was to investigate the blood pressure response during graded exercise test in obese adults. 189 subjects (age: $47.96{\pm}10.23$) were assigned to two groups: non-obese group (N=105, BMI: $22.05{\pm}1.57$, waist circumference: $76.90{\pm}6.17$) and obese group (N=84, BMI: $26.96{\pm}2.51$, waist circumference: $88.29{\pm}6.41$). The subjects underwent health screening and exercise treadmill test from January 2012 to December 2014. Graded exercise test was performed according to the Bruce protocol. Exercise duration (P=0.046) and METs (P=0.015) were significantly lower in obese group than non-obese group. There was no difference in the rate of change in blood pressure response between obese group and non-obese group during exercise, and the recovery rate of systolic blood pressure was delayed in the obese group compared to non-obese group in the first recovery period (P=0.020). The significant factors of increasing rate of change in maximum systolic blood pressure was waist (P=0.046) and hip circumference (P=0.008). In conclusion, these results demonstrate that, for hypertension prevention in obese adults, waist and hip circumference levels should be managed within normal range.
The purpose of this study is to analyze the effects of exercise therapy on serum lipid levels and antioxidants of obese and normal college female students. The subject group composed of ten normal-weight students(below 30% body fat ratio) and ten obese students(above 30% body fat ratio). After a pilot test, the subjects were given an eight-weeks exercise program. Before and after the exercise program, the subjects were given test for serum lipid and antioxidants were analyzed. The SAS program was used in the data analysis. The statistical measurements employed here were T-test, Wilcoxon signed rank test, and Wilcoxon rank sum test. The results of this research are as follows. 1) The effects of exercise therapy on serum lipid levels : Before the exercise therapy, the levels of Total-cholesterol, Triglyceride and LDL-cholesterol of the obese group were highier than those of the normal-weight group. However, the HDL-cholesterol levels were highier in the normal-weight group than in the obese group, but these differences were not significant. With the exercise therapy, the levels of Total-cholesterol increased gradually. The HDL-cholesterol increased gradually, the LDL-cholesterol level decreased in both groups, However, the Triglyceride level decreased in the obese group and increased in normal group, but the difference was not significant. 2) The effects of the exercise therapy on serum antioxidants ; Before exercise therapy, the serum FR and GSSG levels of the obese group were significantly highier than those of the normal-weight group(p=0.00, p=0.04). The serum GSH level of the normal-weight group was highier than that of the obese group, and the serum MDA level of the obese group was highier than that of the normal-weight group. Again these differences were not significant. With exercise therapy, serum FR level was reduced and serum GSSG level significantly increased in both group(obese group p=0.01, normal-weight group p=0.01), The serum GSH level of the obese group significantly increased (p=0.01), and serum MDA level significantly increased in the obese group(p=0.01), but the difference in the normal-weight group was not significant. These results show that regular exercise therapy reduces serum FR levels and activation of antioxidant systems, and suppress oxidative stress. These effects were slightly highier in the obese group than in the normal-weight group. The regular exercise therapy decreased the serum Triglyceride levels more in the obese group than in the normal-weight group. However the improvement of the serum lipid profile may require a longer exercise period than eight weeks. The results show that the exercise therapy was overall more effective in the obese group than the normal-weight group.
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.
The 297 middle school girls in Inchon were devided into three groups according to body mass index(BMI), the under weight group, the normal weight group and obese group to find out relationship between their food habits, food preference, and obesity. The average height and weight are 159.40cm, 67.02kg for obese group, 158.17cm, 39.11kg for under weight group, 156.93cm, 53.78kg for normal weight group. Obese group feels that they are healthy and fat, and their parents are fat also than the other groups. Obese group took more exercise. Total Food habits scores of obese group were lower than the other two groups. In terms of supper, bedtime-smack, unbalanced diet, balanced intake of five basic food groups obese group had lower scores. Especially, intake of carbohydrate, protein, milk group were irregular. There is no significant different in size of meal, overeating eating speed. The preferences of fast food, instant food, high caloric density food were lower in obese group than in the other two groups. The mother of obese group prepared meals according to food composition and prepared little snakes.
This study was conducted to investigate the differences in environmental and psychological factors in children with obesity and to offer useful information for obesity treatment and prevention. 123 children of 5-6th grade in elementary school and their mothers were included in this study and divided into either the obese group and normal group(obese group: 61, normal group: 62) according to the Weight-Length Index(WLI). Results showed that between the two groups there no significant differences in family income, mother's occupation status, educational level, and anthropometric measurement. Nutritional knowledge in the obese group was significantly higher than that of the normal group(p<0.05). The mothers of children with obesity had a higher level of nutritional knowledge than the mothers of normal children(p<0.05). There were no significant differences in food behavior between the obese and normal groups. There were no significant differences in maternal child-rearing practices and in maternal attitude on flood behavior of children. Considering psychological factors ; 72.1% of the children with obesity appraised their body image as obese(p<0.05), and 54.1% of the mothers in obese group perceived their child's body shape as obese(p<0.05). The level of self-esteem were not significantly different when compared between the obese and normal groups. From these results, it was suggested that effective measures for obesity treatment and prevention should include nutritional monitoring, and such efforts need to be maintained in order to help the obese children and their mothers.
This study was an investigation of obesity, food habits and daily nutrient intakes of the 4th grade elementary school students in daejeon. A total of 148 children(male:71, female:77) participated in the study. We classified the subjects into normal group and obese group according to the grade of obesity indices by body fat ratio(BFR), 70% of the male and 31% of the female were obese group. The average height, weight were $140.1{\pm}4.9cm$, $33.0{\pm}3.6kg$(obese group), $141.9{\pm}5.7cm$, $42.0{\pm}3.6kg$(normal group) for the male, $141.2{\pm}6.4cm$, $42.4{\pm}6.2kg$(obese group), $139.5{\pm}6.4cm$, $33.0{\pm}4.5kg$(normal group) for the female. Weight showed a noticeable increase in the obese group, but height was not statistically significant. In dietary habits, it wasn't statistically significant but male obese group showed statistically increase in terms of eating fast(p>0.05) and eating snacks before sleeping(p>0.01) and female obese group was higher in frequency of eating out a month than normal group. Energy intakes of obese group was more than normal group and the average intakes of Vit. A, folic acid, Ca, were below the RI. The average intakes of vit A, vit C, folic acid, Ca, were also below the RI in normal group. The average intakes of vit A, folic acid, Ca, Fe were below the RI in female. Especially in female the intake of Ca was only 53.6%(obese group), 56.4%(normal group) of RI. From these results, we knew prevalence of obesity in elementary school students were high and obese groups were high in energy intakes but low in essential nutrients. Therefore we have to try to prevent and treat childhood obesity. So nutrition education of balanced diet and good dietary habits is needed for elementary school students.
