In this study 4435 insurance applications to the Swiss Life insurance company ("Rentenanstalt") by individuals aged 20-39 years from the time period 1950-1990 were evaluated. Each application contained the self-reported body weight, height, and other informations such as martial status or city of residence. For each individual the body mass index (BMI) was computed and the prevalence of overweight and obesity for each year was calculated using standard definitions. This is the first study which tries to determine the prevalence rates of overweight and obesity in Switzerland over time. The absolute body weight (kg) increased continuously from 1950 to the year 2000. The most pronounced increase was seen in individuals (aged 20-29 years) above the 90th percentile of body weight and BMI, i.e. already overweight and/or obese individuals showed the largest increase in body weight. In men (aged 20-29 years) the prevalence of overweight increased between 1980 and 1990 by more than 10% to a prevalence rate of 25%. In women (aged 20-29 years) the prevalence of overweight increased continuously from 1960 onward and reached a rate of 10.5% in 1990. In the age group of the 30-39 years old individuals no change in the prevalence rates was observed. These data suggest that there is a trend for an increased prevalence of overweight in Switzerland. Since the study sample was not representative for the Swiss population the results have to be interpreted with caution only. Nevertheless the results are in agreement with the trends in other countries and it can be assumed that similar developments do occur also in Switzerland.
在本研究中，对1950年至1990年期间年龄在20至39岁的个人向瑞士人寿保险公司（“养老金机构”）提交的4435份保险申请进行了评估。每份申请都包含自我报告的体重、身高以及其他信息，如婚姻状况或居住城市。为每个人计算了体重指数（BMI），并使用标准定义计算了每年超重和肥胖的患病率。这是第一项试图确定瑞士超重和肥胖患病率随时间变化情况的研究。绝对体重（千克）从1950年到2000年持续增加。在体重和BMI处于第90百分位以上的人群（年龄在20至29岁之间）中，体重增加最为明显，即已经超重和/或肥胖的个体体重增加幅度最大。在男性（年龄在20至29岁之间）中，超重患病率在1980年至1990年间增加了超过10%，达到25%。在女性（年龄在20至29岁之间）中，超重患病率从1960年起持续上升，1990年达到10.5%。在30至39岁的年龄组中，患病率没有变化。这些数据表明瑞士超重患病率有上升趋势。由于研究样本不具有瑞士人口的代表性，因此这些结果只能谨慎解读。尽管如此，这些结果与其他国家的趋势一致，可以假设瑞士也会出现类似的发展情况。
