The effect of a comprehensive rehabilitation programme, including diet therapy, was studied in overweight male myocardial infarction (MI) patients randomly assigned to a rehabilitation group (n = 69) and a control group (n = 64). The results show a mean weight decrease of 3.8 kg in the rehabilitation group and a mean weight increase of 1.1 kg in the control group (t = -5.78, p less than 0.001). The proportion of patients reducing their weight more than 5 kg was 33% in the rehabilitation group and 5% in the control group (chi 2 = 15.6, p less than 0.001). Patient characteristics which significantly affected the weight change by univariate analysis were age, level of overweight, smoking habits, employment situation and social problems. Multivariate analyses yielded a two-variable model with moderate explanatory power in the rehabilitation group. The model includes the variables Body Mass Index and cessation of smoking before MI.
对随机分配至康复组（n = 69）和对照组（n = 64）的超重男性心肌梗死（MI）患者，研究了包括饮食疗法在内的综合康复计划的效果。结果显示，康复组平均体重下降3.8千克，对照组平均体重增加1.1千克（t = -5.78，p < 0.001）。体重减轻超过5千克的患者比例，康复组为33%，对照组为5%（χ2 = 15.6，p < 0.001）。单因素分析中显著影响体重变化的患者特征包括年龄、超重程度、吸烟习惯、就业状况和社会问题。多因素分析在康复组产生了一个具有中等解释力的双变量模型。该模型包括体重指数和心肌梗死前戒烟这两个变量。
