연구배경 본 연구는 여자대학생들의 비만증 예방을 위하여 혈중 렙틴 농도와 신체 계측치, 건강체력을 측정하여 관련성을 비교 분석함으로써 여자대학생의 건강증진을 위한 기초자료를 제공하는데 연구의 목적이 있다. 방 법 연구 대상자는 31명의 여자대학생을 무선표집으로 추출하였다. 혈액을 채취를 통하여 렙틴을 분석하였으며, 생체전기저항법으로 체지방률, 체지방량, 신장, 체중, 허리엉덩이둘레비율, 신체질량지수를 측정하였고, 피부두겹법으로 삼두근 부위, 서혜부, 대퇴부의 두께를 측정하였으며, 건강체력 요인 측정 종목으로는 근력, 근지구력, 유연성, 심폐지구력을 측정하였다. 모든 자료의 통계처리는 혈중 렙틴농도와 체지방률, 신체 계측치, 그리고 건강체력과의 피어슨 상관분석과 다중선형회귀분석, Dubin Watson Test를 실시하였다. 결 과 여자대학생의 혈중 렙틴 농도는 체중, 체지방률, 체지방량, 신체질량지수, 허리엉덩이둘레비율, 허리둘레, 엉덩이둘레, 삼두근 부위, 서혜부, 대퇴부, 배근력, 근지구력, 유연성, 심폐지구력과 유의한 상관관계가 나타났다(p<.05). 그리고 체지방률, 대퇴부는 혈중렙틴 농도의 독립적인 예측인자로 나타났다. 결 론 결론적으로 성인병과 심혈관질환의 원인이 되는 비만을 예방하기 위하여 혈중 렙틴 농도를 적절하게 조절하기 위해서 신체 계측치과 건강체력을 바람직한 방향으로 향상시키는 것이 가장 좋은 전략이라고 사료된다.
Abstract
Background Whether blood leptin concentration is associated with percent body fat, anthropometric parameters, and health-related physical fitness across gender and ethnic groups remain less clear. This study was investigated to the relations of blood leptin concentration with anthropometric parameters(weight, fat mass, waist-hip ratio, WHR, waist circumstance, WC, hip circumstance, HC, body mass index, BMI, triceps thickness, supraileum thickness, thigh thickness) and health-related physical fitness(back muscle strength, sit-up, trunk forward bending, Harvard step test) in 31 Korean female college students. Methods We measured blood leptin concentration, percent body fat, weight, fat mass, triceps thickness, supraileum thickness, thigh thickness, WHR, WC, HC, BMI, back muscle strength, sit-up, trunk forward bending, Harvard step-test. Pearson product-moment correlation, multiple linear regression, and Dubin Watson test were used to investigate the association of blood leptin concentration with anthropometric parameters, and health-related physical fitness to examine the statistical significance using SPSS 12.0 windows. Results Blood leptin concentration was significantly associated with weight, percent body fat, fat mass, BMI, WHR, WC, HC, triceps thickness, supraileum thickness, thigh thickness, back muscle strength, sit-up, flexibility, and PEI respectively. Percent body fat, thigh thickness and trunk forward bending were independent variables which influence blood leptin concentration in multiple linear regression analysis. Conclusions In conclusion, improvements in health-related physical fitness may reduce blood leptin concentration, while being obese may increase blood leptin concentration in Korean female college students.
