The purpose of this study was to investigate the relationship between serum leptin, lipids, bone metabolism markers and nutrient intakes of obese middle-school girls compared to those of normal subjects. Each subject was assigned to either the normal(n=22) or obese groups(n=25) according to their BMI. The subjects were asked for their general characteristics and nutrient intakes using a questionnaire and 24-hr recall method. The serum leptin, lipids and osteocalcin(bone metabolism marker) were measured using blood analyses. The average ages of the subjects in the normal and obese groups were 13.9 and 14.0 years, respectively. The average weight(p<0.001) and BMI(p<0.001) of normal group were significantly lower than those of the obese group. The plant protein intake of the girls in the obese group was lower than that of the normal group(p<0.01). The levels of serum leptin in the obese and normal groups were 18.0 and 10.0 ng/mL, respectively(p<0.001). The serum LDL-cholesterol(p<0.01) and triacylgeride(p<0.05) of the obese girls were higher than those in the normal group. Also, the serum osteocalcin(bone formation marker) in the obese group was lower than that in the normal group(p<0.001). The BMI was negatively correlated to osteocalcin(p<0.001), but positively correlated to the serum leptin(p<0.001). The serum osteocalcin was also positively correlated to the plant protein intake(p<0.05). In conclusion, the excessive increase in weight and % body fat in middle-school students appeared to have a negative impact on bone health. Based on these results, further studies will be needed on the effects of bone metabolism markers, obesity and nutrient intakes for proper bone health.

The factors for the childhood onset obesity were assessed to provide informations for the nutrition education program targeting the primary school children. The subjects of this study were 529 primary school children in Iksan City, Jeon-buk Province. Children were classified into obese(236) and control(293) groups by the obesity index. Anthropometric measurement dietary intake through 24-hour recall method, blood analysis and questionnaire response including nutritional knowledge and attitude, body image recognition and eating habits were conducted The mean age of subject was 12.0 years. The average body weight(p<0.001), BMI(p<0.001), and obesity index(p<0.001) in obese group were significantly different from those in control group; their values in the former were 26.5 kg/m2 and $37.7\%$ and 43.0 kg, 19.8 kg/m2 and $3.2\%$ in the latter, respectively. The average scores of self-satisfaction were significantly different in two groups (p<0.001), 31.2, and 34.1, respectively. Among the obese subjects, $60.6\%$ were unsatisfied or very unsatisfied with their body image, and $76.5\%$ had experiences of weight control and $67.5\%$ took diet control as a weight control method Among mothers of obese subjects, $89.1\%$ were unsatisfied with their children's body image. $64.4\%$ of obese subjects had obese parents. Average intake of energy were $76.7\%$ of RDA in obese group and $74.9\%$ of RDA in control group. Average intake of cereals(p<0.01), potatoes & starch(p<0.01) and eggs(p<0.01) between obese and control subjects were significantly different; 295.4g, 76.2g, 55.6g in the former and 277.9g, 38.1g, 45.6g in the latter, respectively. The mean serum triglyceride(p<0.05), GPT(p<0.05), hemoglobin(p<0.001) concentration of the obses and control subjects were significantly different; in the former, 103.6mg/dL, 24.6U/L, 13.4g/dL, and in the latter, 93.7mg/dL, 19.9U/L, 13.1g/dL, respectively, The results suggest that practical nutrition education for the prevention of childhood onset obese should be provided to primary school children.

The principal objective of this study was to assess the effects of eating habits and health-related lifestyle on blood pressure, $\gamma$-Glutamic acid Peptide Transferase ($\gamma$-GPT), glucose and HDL-Cholesterol (HDL-C). All subjects (261 male, 252 female) were from the Iksan area of Korea, and were at least 50 years of age. The mean systolic blood pressure (SBP), diastolic blood pressure (DBP) and HDL-C for all the subjects was 131.3 mmHg, 78.5 mmHg, and 43.1 mg/dl, respectively. The HDL-C of the $50{\sim}64$ year-old group was higher than that of the over-75-year-old group. The "regular breakfast" group evidenced a lower SBP, $\gamma$-GPT, and higher HDL-C than the "seldom breakfast" group (p<0.001, p<0.001, p<0.01). SBP in the "snacking everyday" group was higher than that of the "seldom snacking" group (p<0.001). As for the frequency of using alcohol, SBP and $\gamma$-GPT for the group using alcohol everyday were higher than those of the non-drinking group (p<0.001, p<0.001), SBP and DBP were higher and $\gamma$-GPT was lower in the group that regularly drank more than 4 glasses of Soju than in the non-drinking group (p<0.001, p<0.05, p<0.001). SBP, DBP, and $\gamma$-GPT for the "heavy smoker" group were higher than those of the non-smoker group (p<0.01, p<0.01, p<0.05). The HDL-C was lower in the "heavy smoker" group than in the "non-smoker" group (p<0.05). The SBP with exercise was as follows: Group 1 ($0.022{\sim}0.073\;kcal/min/kg$) was lower than that of Group 3 ($0.144{\sim}0.161\;kcal/min/kg$) and Group 4 (0.161 kcal/min/kg) (p<0.001). To conclude: advancing age, snacking, and frequent alcohol consumption increased blood pressure; the lowest blood pressure was detected in the group that ate breakfast everyday and in the group that engaged in more frequent exercise; Moreover, $\gamma$-GPT was higher and HDL-C was lower in the smokers' group than in the non-smokers' group. Considering the results of this study, there appears to be an urgent need to instruct aging adults about eating breakfast everyday, reducing smoking, using less or no alcohol, and getting proper and regular exercise.

이다홍(Da-Hong Lee) 동아시아식생활학회 2007 동아시아식생활학회지 Vol.17 No.5

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 24.8 kg/㎡, 39.8 kg, and 32.5% and 18.2kg/㎡, 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 3~4 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.

The purpose of this study was to investigate the relationship between obesity and, erythrocyte SOD (superoxide dismutase) activity and serum antioxidant mineral (Fe, Zn, Cu, Mn and Se) concentrations of adolescents. Subjects were assigned to one of two groups such as obese (BMI≥25, 32 boys, 24 girls) and normal group (18.5<BMI<23, 27 boys, 30 girls). Subjects were evaluated based on anthropometric measurements, 24-hr dietary recalls and blood analysis. The mean age of the total subjects was 13.8 years. The mean weight (p<0.001), BMI (p<0.001) and body fat (p<0.001) of obese were higher than those of normal group. There was no significant difference in nutrient intake between obese and normal groups. SOD activity of obese group was not significantly different from normal groups, in both males and females. However, in the males, serum Cu concentration of obese were significantly lower than those of normal group. In the females, Serum Mn concentration of obese were significantly lower then those of normal group. In the correlation analysis, BMI of the subjects had significantly negative correlations with serum Cu, Zn and Mn. To summarize the results, increase of obesity may lead to decrease of serum antioxidant minerals such as Cu, Zn and Mn. (Korean J Nutrition 40(1): 41~48,2007)
