The study was designed to investigate the relationship between dietary intakes and the obesity of 400 students who were the third grade in middle school in some areas of Seoul. The survey conducted from March 3 to 13 , 1993. The results obtained were summarized as follows :The average height and weight of surveyed subject were similar to that of standard ( the third grade students in middle school in Seoul, 1991) . Compared to the standard weight/height ratio, subject who belonged to overweight and obese group were 16.4% of male students, 16.1% of female students respectively. Female subjects showed higher ratio than male subjects in skipping meals, frequency of snack per day and concern about a dieting . In case of subjects who belonged to weight /height ratio was high, their speed of dining was fast and they have more concern about a dieting. Compared to the amount of the nutritional intakes of RDA, calcium intakes of male and female subjects were deficient. Especially iron intakes of female subjects were deficient. In takes of Calorie (p<0.01) protein(p<0.05) and fat 9p<0.01) of obese group were higher those of non-obese group. Obese group showed good appetite and overeating also . Correlation analysis showed that obese group seemed to the closely associated with relative body weight of parents, family income, frequency of meals per day, frequency of meals per day, frequency of snack per day, speed of dining and overeating .

Purpose: This study was to investigate the effect of a 12-week plyometric training on body composition, physical fitness and bone mineral density in obese male adolescents. Method: Twenty adolescent boys who are obese were randomly assigned to a control group (CON, n=10) or plyometic exercise group (EXE, n=10). The EXE group was performed 3 times per week for 12 weeks. The body composition, physical fitness, and bone mineral density were measured before and after the 12 weeks intervention. Results: The results of this study were as follows: i) In EXE group, the fat mass was significantly decreased between pre and post, whereas the difference of the body weight, BMI, and LBM were not significant. ii) Among the physical fitness factors, grip strength, muscular endurance, and 2 0m shuttle running were significantly improved but flexibility did not show any significant difference. iii) The bone mineral density was significantly improved between pre and post in EXE group. Conclusion: These results suggested that plyometric training for 12 weeks may be effective in improving body composition, physical fitness, and bone mineral density in obese adolescents. Further implications were discussed.

Purpose of this study was to compare serum phospholipid fatty acid composition of obese children with that of normal weight children reside in Kangnung area. Subjects were consisted of 56(41 boys and 15 girls) moderately or severely obese elementary school children, and age and sex-matched normal weight children as a control group. Level of serum phospholipid fatty acids was measured by thin layer chromatography(TLC) followed by gas chromatography(GLC). for male subjects, serum triglyceride(121 $\pm$ 4.7mg/dl) and total cholesterol(180 $\pm$ 37.1mg/dl) concentrations were significantly(p < 0.05) higher in obese group than those for control group(81.5 $\pm$ 2.5mg/dl and 161 $\pm$ 32.0mg/dl, respectively). Obese group showed significantly higher percentage of serum phospholipid myristic acid(C14:0) than the value for control group in both male and female subjects. Obese male subjects had significantly higher percentages of palmitoleic acid(16 : 1), oleic acid(18 : 1), dihomo-${\gamma}$-linoleic acid(20 : 3, $\omega$6) and docosatetraenoic acid(22 : 4, $\omega$6), and lower percentages of eicosenoic acid(20 : 1, $\omega$6), docosapentaenoic acid(22 : 5, $\omega$6), EPA(22 : 5, $\omega$3) and DHA (22 : 6, $\omega$3) compared to values for control male subjects. For male subjects, obese group showed significantly higher ratios of 16 : 1($\omega$9)/16 : 0 and 18 : 1($\omega$9)/18 : 0, and significantly lower ratios of 22 : 5($\omega$6)/22 4($\omega$6), and 22 : 6($\omega$3)/22 : 5($\omega$3) compacted to values for the control group. But there was not significant differences in elongation and desaturation indices of serum phospholipids fatty acid metabolism between obese and control group in female subjects. Most of anthropometric measurements related to obesity were negatively correlated with the percentages of PUFA, $\omega$3 fatty acids or DHA(22 : 6, $\omega$3), and positively correlated with the percentage of myristic acid(14 : 0) or $\omega$6/$\omega$3 ratio in serum phospholipids. Serum triglyceride concentration was negatively correlated with the percentage of PUFA or $\omega$3 fatty acids, and positively correlated with $\omega$6/$\omega$3 ratio in serum phospholipids. These results indicate that obesity related changes in blood lipid levels and metabolism are more significant in male subjects than in female subjects. Also changes in serum phospholipid fatty acid composition observed in obese children appear to demonstrate the increased susceptibility of these children to cardiovascular disease and other related chronic diseases.

BACKGROUND/OBJECTIVES: Spirulina, a blue-green alga, is widely produced and commercialized as a dietary supplement with bio- and immune-modulatory functions. We have previously shown that spirulina had favorable effects on lipid profiles, immune functions, and antioxidant capacity in healthy Korean elderly. Despite favorable effect of spirulina supplementation, some sub-populations have shown a poor response to supplementation. Obesity is a factor related to poor-response. Therefore, the purpose of this study was to determine the immuno-modulation, antioxidant capacity, and lipid-lowering effect of spirulina in obese and non-obese Korean elderly. SUBJECTS/METHODS: The subjects were 78 elderly aged 60-87 years. In a randomized double blind, placebo-controlled study, subjects were fed either placebo or spirulina daily, at 8 g for 12 weeks. Subjects were divided into the non-obese group and the obese group based on body mass index (BMI) criteria for Asians suggested by the International Obesity Task Force: $BMI<25kg/m^2$ (non-obese) and $BMI{\geq}25kg/m^2$ (obese). RESULTS: In the non-obese group, spirulina supplementation showed a significant lowering effect on plasma concentration of total cholesterol and LDL-cholesterol, a significant increase in interleukin (IL)-2 concentration (P < 0.01) and a significant increment (P < 0.05) in IL-2/IL-6 ratio, and a significant increase in total antioxidant status level and a significant decrease in thiobarbituric acid reactive substances level. However, these effects were not observed in the obese group. CONCLUSION: These results demonstrated that blood lipid lowering and immune and antioxidant improving response for spirulina supplement was affected by obesity in Korean elderly.

Carnitine is known to be involved in lipid metabolism and affects body composition as well as energy metabolism of the whole body. Improvement of obesity by L-carnitine supplement suggests that obesity can be related with the abnormality of carnitine metabolism and therefore, plasma carnitine level in normal and obesity groups was investigated. For the characterization of plasma carnitine level in obese people, 60 plasma samples collected from Korean women subjects were analyzed using LC/MS and plasma fatty acid level was also determined using GC/MS. Additionally, several clinical chemical parameters including fasting glucose, cholesterol, AST, and ALT level were measured. All the data obtained were combined and pattern recognition analysis was carried out with the dataset. Obese group showed a different metabolic pattern compared with normal group. Plasma acylcarnitine level of the obese group was found to be $11.7{\mu}g/ml$, which was higher than that of normal group ($8.0{\mu}g/ml$). Statistically significant differences in plasma fatty acid level were not observed between the two groups. Other clinical parameters for the obese group were within normal ranges but AST and ALT levels were slightly elevated compared to normal group. The obese group showed elevated plasma acylcarnitine level.
