  • This study was performed to investigate the relationships between obese index and major risk factors of cardiovascular disease in CVD patients. Anthropometry, food intake patterns, blood pressure, serum lipids and hematological values were analyzed in 550 patients from June, 1991 to August, 1992. The results are as follows: Total food intakes, especially total vegetable food and alcohol intakes were significantly related with obese index, so that the heavier patients tended to consume more carbohydrate and less fat. The blood pressure were observed to have positive correlation with obese index in man but not in women. However, both in men and women, blood levels of TG, TC, and VLDL tended to be related to obese index positively, while HDL and HDL-C were shown to be oppositive. So, it seems that as the degree of obesity is higher the blood pressure and blood lipids patterns worse. Therefore, these results suggest that obesity is one of the major risk factors of CVD, and for prevention & treatment of the disease, controlling body weight by nutritionally adequate diet along with alcohol restriction is necessary.

  • The present study was conducted to investigate the effect of nutrition education program on anthropometric values and boichemical index in obese children who live in Gumi city. The subjects were 16 obese boys, 20 obese girls with obesity index over 130 and 36 of their parents. The nutrition education was carried out by the professional personnel such as doctors, professors, and dietitians. The children were provided with well-balanced lunch meals and had 40min-lectures on the reasonable weight management, 40 min-games and also had regular exercises (stretching, swimming) for 90 mins everyday during 2weeks of the program. The parents had 90 min-lectures on childhood obesity, diet therapy, behavior modification, and exercise for 6times. After the program, obesity index, BMI, % body fat were significantly decreased (p < 0.05) in boys and obese index, BMI, % body fat and WHR were significantly decreased (p < 0.05) in girls. Blood cholesterol and TG levels of girls were significantly decreased (p < 0.05). These findings show that the well-designed nutrition education program for obese children can be an effective approach to help them to improve their anthropometric values and biochemical index.

  • 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.

  • Since binge eating is known to be related to increased risk of body weight fluctuations, it may be associated with increased health risks. This study was conducted to investigate the risks of binge eating on the cardiovascular system of female university students in Korea. Sixty-five female university students who were interested in a weight control program were recruited from a university campus. After personal interviews were conducted using a semi-structured questionnaire, 36 individuals were classified as binge eaters and 29 as non-binge eaters according to modified criteria of the proposed DSM-IV by the American Psychiatric Association(APA). All subjects participate in anthropometric and clinical measurements to evaluate the level of obesity and cardiovascular risks. Binge eating subjects showed no significant differences in obesity index compared to non-binge eating subjects. However, they had a higher level of low-density lipoprotein (LDL) cholesterol and a higher atherogenic index. They also showed close correlations with general obesity and cardiovascular risk factors. Body mass index(BMI) was the main explanatory index related to cardiovascular risk factors according to the stepwise regression analysis. Furthermore, obese binge subjects had higher levels than non-obese binge subjects or non-binge subjects for total cholesterol, LDL-cholesterol, triacylglycerols, atherogenic index, and systolic blood pressure. The findings strongly suggest that obese young women having binge eating episodes might display a greater risk for cardiovascular disease tan that shown for obese non-binge eating women.

  • The purpose of this study is to investigate the differences in body fat distribution between obese boys and girls in high school and the relationship between the precent of body fat and the Broca Index. The survey of data was conducted from November 3rd to the 11th in 1997. The data were analyzed by the use of a mean, standard deviation and a Pearson's correlation coefficient. Measurements of the percentage of body fat and lean body mass were made by a Bioelectrical Impedence while height, weigh and the Broca index were measured by a fatness measuring system. First, measurements of height, weight and the Broca index were made by a fatness measuring system on 1,125 1st year students and 1,076 2nd year students. The result of measurements, 216 obese boys and 100 obese girls appeared to have above 10% of the Broca index. The result of this study can be summarized as follows: 1) Obese boys and girls were grouped by the level of the Broca index as follows: boys, 110-less than 120 60.0%, 120-less than 130 20.8%, 130-less than 140 11.1%, above 140 7.4%. ; girls, 110-less than 120 44.4%, 120-less than 130 32.0%, 130-less than 140 13.0%, above 140 11.0%. 2) Obese boys and girls were grouped by level of the percentage of body fat by Bioelectrical Impedence as follows: boys, less than 20% 5%, 20%-less than 25% 34.7%, above 25% 33.8% ; girls. less than 25% 15.0%, 25%-less than 30% 43.0%, above 30% 42.0%. 3) In obese boys the Broca index score appeared to be positively related to body weight(r = .741, p<.001), the percent of body fat(r=.604, p<.001), lean body mass(r=.375, p<.001), body fluid(r=.445, p<.001l). On the other hand the percent of body fat was not a significant correlation of lean body mass (r= -.074), body fluid(r= -.073). 4) In obese girls, the Broca index score appeared to be positively related to body weight(r= .693, p<.001), the percent of body fat(r=.645, p<.001), lean body mass(r=.531, p<.001), body fluid(r=.532, p<.01), and the percent of body weight score appeared to be positively related to lean body mass(r=.206, p<.01), body fluid(r=.207, p<.01).

  • Recent studies have reported that a subset of obese individuals who were metabolically healthy but obese had more favorable clinical outcomes than obese subjects with metabolic disturbances. The purpose of this study was to evaluate the distribution and agreement of obesity subtypes according to body mass index (BMI) and metabolic syndrome (MS). Furthermore, we examined the differences of nutrient intake among the groups. Data was analyzed for 1,095 female subjects older than 40 years using Korean National Health and Nutrition Survey in 2008. The degree of obesity was classified by two methods, using BMI (obese ${\geq}\;25\;kg/m^2$, not obese < $25\;kg/m^2$) and MS (meet ${\geq}\;3$ criteria among 5 index: waist circumference, triglyceride, glucose, HDL-cholesterol and blood pressure). Subjects were divided into 4 groups according to $2{\times}2$ cross table: non-obese without MS, non-obese with MS, obese without MS and obese with MS. Nutrient intakes were compared among 4 groups. The results showed that the proportions of non-obese without MS, non-obese with MS, obese without MS and obese with MS were 47.6%, 13.6%, 16.6%, and 22.2% of total subjects, respectively. The agreement (kappa value) of two methods was 0.354 (fair) in total subjects, 0.365 (fair) in 40-60 year old subjects and 0.304 (fair) in ${\geq}\;61$ year old subjects. In ${\geq}\;61$ years old subjects, intakes of percentage energy from carbohydrate, percentage of energy from fat, calcium, phosphorous, sodium, vitamin A, carotene, thiamine, riboflavin and niacin were significantly different among the groups. In contrast, the subjects of 40-60 years old, no differences in nutrient intakes were observed. In conclusion, there were differences in nutrient intakes among the groups subdivided by obesity and MS, especially in elderly female subjects. Individualized dietary guideline for subtype of obesity will be needed to treat metabolic disturbance of obesity.

  • This study set out to investigate the effects of 16-week nutrition education and exercise intervention run by a public health center on the physical activities and dietary patterns of obese children at the before, after, and after one month point. After the program, the obese index of the obese children dropped by 5.9% from 38.4% to 32.5%. One month after the end of the program, their obese index increased by 1.4% to 33.9% (p < 0.001). The obese children's hours of walking of physical activities increased to 2.6 hours from 1.2 hours after the program and remained at the 2.6 hours range one month after the end of the program (p < 0.01). The total scores of their food habits increased to 10.4 points from 9.1 points after the program and 10.3 points one month after the end of the program with significant differences (p < 0.01). The total scores of their eating behavior made a significant increase to 6.5 points from 5.3 points after the program and then dropped to 5.9 points one month after the end of the program (p < 0.05). As for changes to their dietary pattern scores according to the obese index, only the food habits scores showed significant main effects of term (p < 0.05). According to these results, there is still a need to develop proper programs to help them increase regular exercise, improve their physical activities by cutting down time with TV, computer, Internet, and video games, and enhance their nutritional knowledge and to provide them with ongoing management and guidance until the improved food habits and eating behavior become part of their habits.

  • This study was conducted to investigate the effects of ethanol extract from Lycii folium (L. folium) leaves on obesity index, serum lipids, homocysteine, leptin, ghrelin, and glucose in obese rats. Sprague-Dawley rats were administrated high-fat diets to induce obesity. Then, obese rats were divided into three diet groups: a basal-diet obese group (BO group), high-fat diet obese group (FO group), and high-fat diet plus L. folium extract obese group (FLEO group). Three groups were each fed experimental diet for 8 weeks. There were no significant differences in body weight and FER among the groups. However, obesity index such as Ro?hrer index, Lee index, and T.M. index of FLEO group was significantly decreased as compared to FO group. While serum triglyceride of BO group was significantly decreased as compared to FO group, there were no significant differences in serum lipids, homocysteine, leptin, ghrelin and glucose between FLEO group and FO group. In conclusion, these results indicated that ethanol extract from L. folium leaves might be beneficial with anti-obese effect by reduction of obesity indices in obese rats.

  • The purpose of this study was to determine the body weight control, food habits and nutrient intakes according to the obese index in male middle school students. This study was carried out through questionnaires and measurement by body fat analyzer (Inbody 4.0). The subjects were 275 male middle school students in Iksan. Chonbuk province. The average age, height, weight, and BMI of the subjects were 14.4 years old, 167.8 cm, 60.2 kg and $21.3kg/m^2$, respectively. Seventeen point one percent of the subjects were the underweight group, 47.6% were the normalweight group, and 35.3% were the overweight group by the classification of the Korean Pediatrics Society standard. Body fat of underweight, normalweight, and overweight were 16.1%, 19.0%, and 26.6%, respectively. Thirty one point nine percent of underweight, 39.7% of normalweight. and 31.9% of overweight had misperceptions of their weight (p<0.001). Sixty two point two percent of the males were dissatisfied with their body weight, and 55.3% of the whole tried to reduce their body weights. Even though they were normalweight, half of them dissatisfied with their weight. The source of weight control method was friends and family, TV radio, Internet, and school nutrition education, in order. The subjects exercised 3.4 days per week, 70.2 minutes per day, but it was not different significantly by the obese index. Forty percent of the subjects had meals fast, 58.5% of them have biased food habits even if they didn't differ by the obese index. Activity rate was different by the obese index significantly (p < 0.05), the number of severe activity was most in underweight. In conclusion, nutrition education programs should contain the necessity of normalweight, and regularity of lift habits and activities for energy expenditure in overweight students. It made them to recognize their weight correctly, establish healthy body images, and raise the ability to promote health and improve nutritional status.

  • To study the factors related to childhood obesity, 75 subjects were selected as an obese group and 75 subjects were selected as a control group according to their obesity index and BMI among the 583 children of 5th and 6th grade in elementary school in Seoul. For each subject, skinfold thickness was measured, information on the characteristics of family, nutrient intake and activity time of the subjects were obtained by questionnarie. The results were summarized as following: 1) Parents' obesity indices of obese group were significantly higher than those of control group(Father's Obesity Index : P<0.01, Mother's Obesity Index : P<0.05). 2) Questions about eating rate and behavior showed that subjects in obese group were significantly faster in their eating rate(p<0.05) and always more eager to eat food(p<0.001) compared to control group. 3) Dietary intake data showed that average daily intake of all the nutrients exceeded Korean recommended dietary allowances for the age group. In female children, fat intakes of obese group were significantly higher than control group(P<0.05). There was no such significant difference in male subjects. 4) Activity time record of subjects reveal that there was a trend for males to spend more time in moderate and high activity and less time in light activity compared to females. Subjects in obese group spent significantly more time for light activity(P<0.001) and significantly less time for moderate activity (P<0.001) compared to subjects in control group. The difference of activity was more pronounced in male subjects. 5) Correlation matrix of the variables showed that obesity index, BMI, and skinfold thickness of the subjects were highly correlated with each other. These indices were positively correlated to parent's obesity indices and the time spent for light activity, but negatively correlated to the time spent for moderate activity. Nutrient intakes were not significantly correlated to obesity indices. Form the results shown above, although both obese and control groups are from high socioeconomic class, obese children tended to come from family with fat parents. They eat fast and are always eager to eat. They tend to eat more fat but are very different from controls in nutrient intake. Obese children are significantly lower in their actinity compared to controls. So, for the prevention and treatment of childhood obesity, it seems to be more important to increase their activity levels.
