The relationship between % Body Fat and Blood Pressure, Total Cholesterol, and Serum Lipoprotein Ratios in College Students

대학생의 체지방 수준과 혈압, 총콜레스테롤 및 혈청 지단백비율과의 관계

The purpose of this study was to develop cardiovascular health related percent body-fat standards that may be applied to epidemiologic investigations of the prevalence and incidence of obesity in adolescents, pediatric health screenings, and youth fitness tests. The subjects included 102 males and 80 females aged 19～22years. All subject were Honam University Students Total body fat was derived from body density which was estimated from age and the triceps and subscapular skinfold thickness measured with Lang calipers to the nearst l.0mm. Serum total cholesterol and lipoprotein cholesterol fraction(HDL-CLDL-C) were measured from blood obtained from fore arm vein after blood pressure measurement. In analyses to determine critical fat levels associated with elevated CDD(Chronic Degenerative Disease) risk factors;male and female were grouped by level of percent fat as follows: male, 〈 10%, 10-14.9%, 15-19.9%, 20-24.9%, and $\geq$ 25%;female, 〈 20%, 20-24.9%, 25-29.9%, 30-34.9%, and $\geq$ 35%. As the results of the data, the conclusions were as follows: 1. A dose respones effect was observed between blood pressure and percent body fat in males and females; in contrast, total cholesterol and lipoprotein ratios were relatively independant of percent fat among the lower four fatness group in males and the lower three fatness groups in females. 2. The percentage of subjects in the uppermost quintile for S-Bp, D-Bp, TC, LDL/H was significantly(P〈.05) greater than expected by change alone(20%) in males with $\geq$ 25% fat and in females with $\geq$ 30% fat females with $\geq$35% had even greater representation in the uppermost quintile of all CDD risk factors compared to females with 30-34.9% fat.
