Development and outcome of indices of obesity in normal children.
Based on the Zürich longitudinal growth study, differences are analyzed between those children who later became light adults (later light) and those who later became heavy (later heavy) adults. This is of interest to discover how and when overweight develops, and which variables are most affected (weight, body mass index, circumferences and skinfolds are studied). A further question is whether maturation proceeds differently in these children. The principal idea is to split the sample with respect to adult body mass index into three parts, and to analyse the two extreme groups. It is shown that structural average curves for these subgroups lead to a substantial insight into the processes going on in different variables. Whereas maturation is not much different, subjects later heavy gain substantially more in fat and body mass index from about 4 to 5 years onwards. The natural pattern of ups and downs becomes exaggerated in subjects who are to become heavy at adult age. In those phases where it is natural to build up body mass index there is not much of a difference. In phases where later lean subjects hardly increase their body mass index, later heavy subjects continue to build it up substantially.
