The purpose of this study was to examine relationships between aerobic fitness (AF), fatness, and coronary-heart-disease (CHD) risk factors in 12- to 13-year-olds. The data were obtained from 208 schoolchildren (100 boys; 108 girls) ages 12.9 +/- 0.3 years. Measurements included AF, indices of obesity, blood pressure, blood lipids and lipoproteins, fibrinogen, homocysteine, and C-reactive protein. An inverse relationship was found between AF and fatness (p <or= .05). Fatness was related to a greater number of CHD risk factors than fitness was (p <or= .05). Further analysis revealed fatness to be an independent predictor of triglyceride and blood-pressure levels (p <or= .05). Our findings indicate that, for young people, fatness rather than fitness is independently related to CHD risk factors.
本研究的目的是调查12至13岁儿童的有氧适能（AF）、肥胖程度与冠心病（CHD）风险因素之间的关系。数据来自208名12.9±0.3岁的学童（100名男孩；108名女孩）。测量指标包括有氧适能、肥胖指数、血压、血脂和脂蛋白、纤维蛋白原、同型半胱氨酸和C反应蛋白。研究发现有氧适能与肥胖程度之间呈负相关（p≤0.05）。与适能相比，肥胖程度与更多的冠心病风险因素相关（p≤0.05）。进一步分析显示，肥胖程度是甘油三酯水平和血压的独立预测因素（p≤0.05）。我们的研究结果表明，对于年轻人来说，与冠心病风险因素独立相关的是肥胖程度而非适能。
