摘　　要：研究目的:探讨肥胖少年颈围(NC)、腰围(WC)与心肺耐力(CRF)及心血管疾病(CVD)危险因素的关系,探讨CRF对心血管健康的影响,为心血管疾病的早期预防提供科学依据。研究方法:招募8~17岁肥胖少年57名(男25人,女32人),平均年龄13.5岁。使用皮尺对所有受试者进行NC、WC测量。功率自行车递增负荷试验测量心肺耐力(CRF),CRF水平通过气体代谢分析仪所测定的峰值摄氧量表示。测量安静收缩压(SBP)、舒张压(DBP),检测空腹血糖(FPG)、总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDLC)、低密度脂蛋白胆固醇(LDL-C)。结果:调整年龄、性别后,NC、WC、腰围身高比(WHt R)均与SBP、DBP、TG正相关,均与CRF负相关;NC、WC均与HDL负相关。调整年龄、性别、CRF后,NC是高SBP、高TG、低HDL-C的独立危险因素,OR值分别为1.278(95%CI:1.027,1.590)、1.342(95%CI:1.017,1.772)、1.287(95%CI:1.042,1.589),WC是高SBP的独立危险因素,OR值为1.095(95%CI:1.013,1.185),但是WC对高TG的预测效果受到CRF的影响。调整年龄、性别后,CRF与TG负相关,对TG变异的解释增加12.1%(P<0.05)。与没有CVD危险因素者相比,具有1个以上危险因素者,NC、WC、WHt R均显著较高(P<0.05),CRF显著较低(P<0.05)。结论:肥胖少年的颈围、腰围与血压、血脂关系密切,但关联程度受到心肺耐力的调节,心肺耐力是血脂水平的保护因素。此外,颈围、腰围对心肺耐力也具有预测作用,颈围、腰围越小,心肺耐力越好。建议今后对肥胖少年的相关研究需要重视颈围、腰围的测量,重视心肺耐力对保护心血管健康的作用。Objectives： To investigate the relationship of neck circumference （NC）, waist circum- ference （WC） and cardiorespiratory fitness （CRF） with cardiovascular disease （CVD） risk fac- tors, and provide scientific basis for the primary prevention of cardiovascular diseases. Methods： Recruited 57 obese adolescents （25 boys, 32 girls） aged 8~ 17. The average age is 13.5. Tapes were used to measure the NC and WC. CRF levels were expressed by peak oxygen uptake, which was measured with the gas metabolism analyzer in the graded exercise test. Blood pressure （BP）, lipids, glucose were assessed. Results： Multiple linear regression models showed that after adjust- ing for age and gender, NC, WC, waist height ratio （WHtR） were all positively correlated with SBP, DBP, TG, and were all negatively correlated with CRF. NC, WC were negatively correlat- ed with HDL. NC was one of risk factors of high SBP （OR：1.278,95%CI： 1.027, 1.590）, high TG （OR： 1.342, 95%CI： 1.017,1.772） and low HDL-C （OR： 1.287, 95%CI： 1.042,1.589）, in- dependent of age, gender, CRF, WC was one of risk factors of high SBP （OR：1.095,95%CI： 1.013, 1.185）, but the prediction of high TG was affected by CRF. After adjustment for age and sex, CRF was negatively correlated to TG. Compared with those of no CVD risk factors, adoles- cents of more than 1 risk factors, NC, WC, WHtR were significantly higher （P〈0.05）, CRF was significantly lower （P〈0.05）. Conclusion： NC and WC are both associated with blood pres- sure and blood lipid in obese adolescents, but the correlation degree is affected with cardiorespira- tory fitness. CRF is a protective factor for blood lipid level. What＇ s more, NC and WC could pre- dict the CRF. NC and WC are shorter, CRF is better. It is suggested that studies of obese adoles- cents should pay attention to the measurement of neck circumference and waist circumference, and the CRF should also be placed great emphasis in the protection of cardiovascular health in th
