[Longitudinal data of the Kiel Obesity Prevention Study (KOPS)].
The Kiel Obesity Prevention Study (KOPS) has been performed since 1996. Examinations were performed at age 6, 10 and 14 years. In addition, birth weight as well as height and weight at age 2 years were collected retrospectively. For the study 4,997, 1,671 and 748 children were recruited at baseline (at age 6 years) as well as at 4 and 8-year follow-up, respectively. In this paper we will analyze and discuss (i) the important time period for preventive measures, (ii) effect sizes needed for successful interventions and (iii) suitable approaches for preventive measures. The main results were: (i) at age 6 years persistence of overweight was 69% while at younger ages persistence was 21% only. Thus, school entry was shown to be an important period for preventive measures. (ii) Interventions have to reduce energy balance by 140 kcal/day to prevent overweight (e.g. a reduction of energy intake). (iii) Prevention programs should involve the family and focus on increasing physical activity.
