The relationship between risk factors for CHD such as physical activity, cardiovascular fitness, subcutaneous body fat, dietary intake characteristics, age, and sex with the blood lipid profile was examined in 39 boys and 58 girls aged 10-15 yr. In boys, a high level of physical activity was related to higher concentrations of HDL-C (r = 0.32, P < 0.05), as well as to lower concentrations of VLDL-C, total triglycerides (TG), and the ratio of total cholesterol (TC) to HDL-C (r = -0.42; -0.40, both P < 0.01; and -0.37, P < 0.05). A high sum of 10 skinfolds (sigma 10SF) was related to a higher ratio of TC/HDL-C (r = 0.35; P < 0.05). In girls, physical activity was positively related to HDL-C (r = 0.29; P < 0.05). The sigma 10SF showed a negative association with Apo A-I and HDL-C (r = -0.26, -0.29, both P < 0.05) and a positive association with apolipoprotein B (Apo B) (r = 0.28, P < 0.05). Cardiovascular fitness was not significantly related to any of the blood lipid concentrations, in either boys or girls. Intake of saturated fats and dietary cholesterol was positively related to TC levels in boys, but the associations failed to reach statistical significance (r = 0.34 and r = 0.31, P > 0.05) due to the small sample size (N = 32).(ABSTRACT TRUNCATED AT 250 WORDS)
对39名10至15岁男孩和58名同龄女孩进行了研究，以探讨冠心病风险因素，如身体活动、心血管健康状况、皮下体脂、饮食摄入特征、年龄和性别与血脂谱之间的关系。在男孩中，高水平的身体活动与较高的高密度脂蛋白胆固醇（HDL-C）浓度相关（r = 0.32，P < 0.05），同时与较低的极低密度脂蛋白胆固醇（VLDL-C）、总甘油三酯（TG）浓度以及总胆固醇（TC）与HDL-C的比值相关（r = -0.42；-0.40，均P < 0.01；以及-0.37，P < 0.05）。10处皮褶厚度总和（sigma 10SF）较高与TC/HDL-C比值较高相关（r = 0.35；P < 0.05）。在女孩中，身体活动与HDL-C呈正相关（r = 0.29；P < 0.05）。sigma 10SF与载脂蛋白A-I（Apo A-I）和HDL-C呈负相关（r = -0.26，-0.29，均P < 0.05），与载脂蛋白B（Apo B）呈正相关（r = 0.28，P < 0.05）。心血管健康状况与男孩或女孩的任何血脂浓度均无显著相关性。男孩中饱和脂肪和膳食胆固醇的摄入量与TC水平呈正相关，但由于样本量较小（N = 32），这些关联未达到统计学显著性（r = 0.34和r = 0.31，P > 0.05）。（摘要截选至250字）
