어촌과 도시지역 여고생의 영양실태 , 체조성 및 혈액성상에 관한 연구 = A Study on Nutrients Intakes , Body Composition and Hematological Status of High School Girls in Fishing and Urban Areas

다국어 초록 (Multilingual Abstract)

The purpose of this study was to examin height, weight and body composition, nutrient intakes and serum lipids for high school girls in urban and fishing area. The subjects consisted of 78(44 fishing and 34 urban) high school girls aged in average 17.3 and 17 years. Their dietary intakes were assesed for 1 day by means of 24 hours dietary recall method. Concentrations of serum lipids, percentage of body fat and volume of total body water were measured. The mean energy intake of the subjects were 1431 ㎉ in fishing and 1659 ㎉ in urban area. The subjects in fishing area(urban) consumed 58(67) g protein, 27(36) g lipid, 459(634) ㎎ calcium, 676(945) ㎎ phosphorous, 11(14) ㎎ iron, 786(574) RE retinol, 2.8(3.6) ㎎ tocopherol, 0.9(1.0) ㎎ thiamin, 1.2(1.1) ㎎ riboflavin, 16.9(20.5) ㎎ niacin and 64.1(92.8) ㎎ ascorbic acid, respectively. Energy, calcium, iron and tocopherol intakes were lower than the Korean RDA in both girls. The mean percentage of body fat of fishing girls were 19.8% and significantly lower than 25.6% in urban. These values seem to fall in the desirable range in fishing girls, but high school girls in urban is seemed to overweight. The mean saturated fatty acid(SFA), monounsaturated fatty acid(MUFA), polyunsaturated fatty acid(PUFA) and dietary choesterol(Chol) intakes were 7.3 g, 8.1 g, 7.2 g and 263 mg for fishing girls were 13.1 g, 12.1 g, 9.1 g and 216 mg for urban girls respectively. The fat, SFA and MUFA intakes in fishing girls were significantly lower than urban girls. The P/M/S ratio was 0.9/1.1/1 for fishing, was 0.7/0.9/1 for urban. The mean serum triglyceride(TG), total choesterol, HDL-cholesterol, LDL-cholesterol concentrations were 77.7(61.8) ㎎/dl, 124.5(142.3) ㎎/dl, 59.3(22.4) ㎎/dl and 49.6(1(Y7.8) ㎎/dl in fishing girls(urban girls), respectively. All of these values seem to fall in the desirable range but HDL-chlesterol concentrations in fishing girls were significantly higher than urban girls and LDL-cholesterol concentrations in fishing girls were significantly lower than urban girls. There were positive correlation between body fat percent and total cholesterol or LDL-cholesterol concentration : negative correlations between between body fat percent and HDL-cholesterol concentration: positive correlation between fat intake and LDL-cholesterol concentration : negative correlation between serum HDL-cholesterol concentration and fat or SFA or MUFA intakes.
