A Comparative Study on the Serum Lipid Levels and the Dietary Intake of Physical Education Major and Non-Major Male Students: Kyoung A Choi, Myung Hee Kim; Korean J Community Nutr 2003;8(5):667-674. Published online October 31, 2003

Abstract PDF: The paper examines the effect of physical exercise on blood lipid with young male students. Our analysis is based on the body measurement, food intake and blood lipid component for 70 male students of Kongju National University who either major in physical exercise (group A) or do not major in physical exercise (group B). The average weight of group A is 71.97 +/- 10.79 kg while that of group B is 67.57 +/- 8.66 kg. The former is significantly higher (p < 0.05) than the latter. The SBP of group A (128.20 +/- 11.40 mmHg) is significantly (p < 0.001) higher than that of group B (136.27 +/- 13.18 mmHg). In terms of the intake of total kcal, group A marks significantly higher than group B; group A goes with 2190.26 +/- 581.96 kcal and group B goes with 2392.94 +/- 769.03 kcal. The comparative analysis of the three nutrient intake shows that the intake proportions for group A are carbohydrate 55.08 +/- 6.03%, protein 15.58 +/- 2.75%, and lipid 29.34 +/- 5.16% while the intake proportions for group B are carbohydrate 57.29 +/- 8.09%, protein 15.62 +/- 3.26%, and lipid 27.10 +/- 6.90%. For group A, the vitamin B1 intake amounts to 1.50 +/- 0.5 mg which fulfills 100% of RDA, and the niacin intake amounts to 16.57 +/- 5.54 mgN.E which is less than RDA. In contrast, both intakes for group B are more than the RDA. In the case with minerals except calcium, both group A and B mark more intake than RDA. Group A's calcium intake is 517.12 +/- 200.63 mg and group B's is 409.56 mg. The total cholesterol intake for group A is 447.00 +/- 245.08 mg which is significantly (p < 0.05) higher than for group B with 352.35 +/- 200.25 mg. The total cholesterol in the lipid of serum is 151.30 +/- 12.92 mg/dl for group A and 182.30 mg/dl for group B, where the dominance of group B over group A is true at the level of significance 0.01. In the case with triglyceride, group A is 107.57 +/- 31.60 mg/dl and group B is 108.07 +/- 33.93 mg/dl so that the group difference is non-significant. The HDLcholesterol for group A is 54.67 +/- 6.49 mg/dl which is significantly higher (p < 0.001) than for group B with 36.13 +/- 4.64 mg/dl. We conclude that regular exercise may have an effect on blood lipid metabolism among young males.

Serum Lipids by Gender, Age and Lifestyle in Korean Adults: Mi Kyung Kim; Korean J Community Nutr 2000;5(1):109-119. Published online March 31, 2000

Abstract PDF: The purpose of this study was to measure serum lipids concentrations by gender and age, and to investigated the relation of serum lipids levels to cigarette smoking alcohol intake exercise and menopausal status in Korean adults. The subjects consisted of 463 healthy adult(29- men and 173 women) volunteers who were visiting the health Promotion Center in the Asan Medical Center from July 1, 1994 to July 22, 1994 Subjects were ambulatory free-living people and aged 20- 80 years, Anthropometric measurement was performed and serum triglyceride(TG), HDL-cholesterol and total cholesterol(TChol) concentrations were measure by automatic system(Hitachi 736-40). Data on life styles were obtained using structured questionnaires issued by a trained interviewer, All data were statistically analyzed by PC-SAS(Version 6.04) Serum concentrations of triglyceride and total cholesterol was higher(p<0.05) in men than in women, and serum HDL-cholesterol was lower(p<0.05) in men than in women. The prevalence of hyperlipidemia(TG>170 mg/dL and TChol>220 mg /dL) was 12.5% in men and 4.1% in women. The levels of serum triglyceride, total cholesterol and BMI increased with age in women. The distribution curves of serum triglyceride, total cholesterol and LDL-cholesterol of women were located in lower increased more rapidly with aging than in men, The distribution curves of BMI of women increased with aging after the thirties, The BMI of women was located in higher levels than of men in their sixties. The serum concentration of triglyceride and total cholesterol of male current-smokers and non-smokers were significantly(p<0.05) higher than those of ex-smokers. The concentrations triglyceride the male current0drinkers were higher(p<0.05) than those of male non-drinkers. In non-smokers and non-drinkers, serum TG concentration were lower (p<0.05) than those of current-smokers and current-drinkers. In exercisers, the serum triglyceride concentration was significantly(p<0.05) lower than in non-exercisers. In postmenopausal woman BMI and serum concentrations of TChol, TG and LDL-Chol were significantly by age and gender and smoking alcohol drinking, exercise and menopausal staus might be a better indicator to predict serum lipids in both genders.
