对36例肥胖青少年冠心病危险因素的发生率及20周饮食和运动的影响进行了研究。确定了以下危险因素的值：血清甘油三酯水平、高密度脂蛋白胆固醇水平、总胆固醇水平、收缩压和舒张压、最大工作能力、肥胖和有家族史的冠心病。在受试者中，97%的人有四个或更多的危险因素。两名受试者拥有全部八种危险因素。这些青少年被随机分配到对照组、饮食治疗和行为改变组，或者运动、饮食治疗和行为改变组。从治疗前到治疗后，后两组的多重风险分别降低了14.8%和41.4%。饮食行为改变组与对照组比较，差异无统计学意义。相比之下，运动-饮食-行为改变组比其他两组中的任何一组都能更好地降低多重风险(P<0.01)。结论是，肥胖青少年患冠心病的风险很高，运动加上适度的饮食限制可以降低多发性冠心病的风险。
The incidence of coronary heart disease risk factors and the effects of 20 weeks of diet and exercise were studied in 36 obese adolescents. Values for the following risk factors were determined: serum triglyceride level, high-density lipoprotein-cholesterol level, total cholesterol level, systolic and diastolic BP, maximum work capacity, obesity, and presence of coronary heart disease in the family history. Of the subjects, 97% had four or more risk factors. Two subjects possessed all eight risk factors. The adolescents were randomly assigned to either a control, diet therapy and behavior change, or exercise, diet therapy, and behavior change group. From pre- to posttreatment, a 14.8% and 41.4% reduction in multiple risk was noted for the latter two groups, respectively. No significant difference between the control group and the diet and behavior change group was found. In contrast, the exercise-diet-behavior change group reduced multiple risk (P less than .01) more than either of the other groups. It was concluded that obese adolescents are at high risk for the development of coronary heart disease and that exercise in addition to moderate dietary restriction can result in the reduction of multiple coronary heart disease risk.
