This study aimed at reducing risk factors for coronary heart disease through improving living habits in the population. It was conducted in a rural community in the canton of Zürich; a similar community without an intervention programme served for comparison. Data from questionnaires and examinations in random population samples examined at the start and a year later (1974-75) indicated that a favourable effect on smoking habits was achieved while blood-pressure levels were reduced in both communities, presumably because hypertensives were referred to their physician in the intervention as well as in the control area. Serum-cholesterol level and eating habits could not be demonstrably influenced. However, there was a trend toward weight reduction and an increase in physical activity in the intervention community. On comparing the initial findings, based on random samples, with an independent new sample examined at the end of the study, no overall changes in risk-factor levels could be found in the general population but the statistical power to show an effect is impaired by small numbers. The intensity of the intervention programme was limited by the available means; it was well accepted by the population.
本研究旨在通过改善人群的生活习惯来降低冠心病的风险因素。该研究在苏黎世州的一个农村社区进行；一个没有干预计划的类似社区用作对照。1974 - 1975年在研究开始时和一年后对随机抽取的人群样本进行问卷调查和检查的数据表明，干预对吸烟习惯产生了积极影响，同时两个社区的血压水平都有所降低，这可能是因为干预区和对照区的高血压患者都被转诊给了医生。血清胆固醇水平和饮食习惯没有受到明显影响。然而，干预社区有体重减轻和身体活动增加的趋势。在将基于随机样本的初始结果与研究结束时检查的一个独立新样本进行比较时，在普通人群中未发现风险因素水平的总体变化，但由于样本数量少，显示出效果的统计效力受到了损害。干预计划的强度受到可用资源的限制；该计划受到了人群的广泛接受。
