We explored the associations between aerobic physical fitness with blood lipids and a composite index of blood lipids and fasting glycaemia in adolescents, analysing possible interactions with weight status.
Body mass index and aerobic physical fitness was measured in 2090 adolescents (1034 males and 1056 females) 13-18.5 years by using the 20-m shuttle run test. Plasma glucose, total, high density lipoprotein (HDL) and low density lipoprotein (LDL) cholesterol, triglycerides, apolipoprotein (apo) A-I, apo B-100 and lipoprotein(a) [Lp(a)] were measured in 460 of the 2090 subjects. After adjustment for confounding factors, a continuously distributed summary score for blood lipids and fasting glycaemia was significantly related to aerobic fitness in males (P=0.018) and females (P=0.045, from the 2nd to the 4th quartile of aerobic fitness). After adjustment for gender, age, sexual maturation and economic status, aerobic fitness was related to the composite index of blood lipids and glycaemia in both overweight and non-overweight adolescents (P< 0.05). However, for the same level of aerobic fitness, the composite index of blood lipids and glycaemia was significantly higher in overweight adolescents (P=0.001). After setting the minimal aerobic fitness standards to present a healthy lipid profile, about 50% of males did not reach such values.
Our data suggest that both aerobic fitness and weight management are associated with a composite index of blood lipids and glycaemia in adolescents. Our study also provides the minimal levels of aerobic physical fitness associated with a favourable lipid profile in male adolescents, a new tool which should be adopted by schools as "aerobic fitness standards".
我们探讨了青少年有氧体能与血脂及血脂和空腹血糖综合指数之间的关联，并分析了与体重状况可能存在的相互作用。
通过20米往返跑测试，对2090名13至18.5岁的青少年（1034名男性和1056名女性）进行了体重指数和有氧体能测量。在这2090名受试者中，对460人测量了血浆葡萄糖、总胆固醇、高密度脂蛋白（HDL）和低密度脂蛋白（LDL）胆固醇、甘油三酯、载脂蛋白（apo）A-I、apo B-100和脂蛋白(a)[Lp(a)]。在对混杂因素进行调整后，血脂和空腹血糖的连续分布综合评分与男性（P=0.018）和女性（有氧体能第二至第四四分位数，P=0.045）的有氧体能显著相关。在对性别、年龄、性成熟度和经济状况进行调整后，有氧体能与超重和非超重青少年的血脂和血糖综合指数均相关（P<0.05）。然而，对于相同水平的有氧体能，超重青少年的血脂和血糖综合指数显著更高（P=0.001）。在设定最低有氧体能标准以呈现健康血脂谱后，约50%的男性未达到该值。
我们的数据表明，有氧体能和体重管理均与青少年的血脂和血糖综合指数相关。我们的研究还提供了与男性青少年良好血脂谱相关的最低有氧体能水平，这是一种新工具，学校应将其作为“有氧体能标准”采用。
