The aim is to analyze and compare individual body mass index (BMI) growth patterns of adults from Switzerland and the US.
The analyses are based on data from two population representative longitudinal household surveys, one from Switzerland, the other from the US. Each data set contains up to four data points for each adult individual. We use multilevel models for growth.
It can be shown that growth patterns are different in different cohorts in the two countries: there are only small growth differences in the youngest and oldest, but large differences in the middle ages. The individual BMI increase of the middle-aged Swiss amounts to only half of that in the comparable US individuals.
Given the much higher BMI level, especially in the youngest cohort, this points to severe obesity problems in the US middle-aged population in the near future. A positive correlation between individual BMI level and growth may emphasize this fact.
分析和比较瑞士和美国成年人的个体体重指数（BMI）增长模式。
分析基于来自瑞士和美国的两项具有代表性的人口纵向家庭调查的数据。每个数据集包含每个成年人最多四个数据点。我们使用多层次模型进行生长分析。
可以表明，两国不同队列的生长模式不同：在最年轻和最年长的人群中，生长差异较小，但在中年人群中差异较大。瑞士中年人的个体 BMI 增长仅为可比美国个体的一半。
鉴于更高的 BMI 水平，尤其是在最年轻的队列中，这表明美国中年人群在不久的将来将面临严重的肥胖问题。个体 BMI 水平与生长之间的正相关可能强调了这一事实。
