The effects of screening a group of 98 general practitioners and teachers for fitness, body mass index, serum cholesterol and lifestyle measures--smoking, alcohol consumption, diet and exercise habits were assessed 6 and 24 months later by postal questionnaire (response rate 98%). There was no significant difference for any screened measure between zero months and 6 or 24 months except that subjects found to have a raised cholesterol at 0 months were subsequently more likely to reduce the proportion of fat in their diet. There were no significant differences between screened subjects compared with a control group of non-screened doctors and teachers at 24 months. The number of subjects with abnormal measurements found at the screening session who altered to measurements within the normal range was equal to the number of subjects who changed from normal to abnormal measurements over the 2 year period of study.
对98名全科医生和教师进行了健康状况、体重指数、血清胆固醇及生活方式指标（吸烟、饮酒、饮食和运动习惯）筛查，并在6个月和24个月后通过邮寄问卷进行评估（回复率98%）。除了在0个月时被发现胆固醇升高的受试者随后更有可能减少饮食中的脂肪比例外，0个月与6个月或24个月时的任何筛查指标均无显著差异。在24个月时，筛查对象与未筛查的医生和教师对照组之间无显著差异。在为期2年的研究中，筛查时测量值异常并转变为正常范围的受试者数量与测量值从正常转变为异常的受试者数量相等。
