Haben gestillte Kinder ein geringeres Risiko, später an Übergewicht zu leiden? Diskussion einer Metaanalyse

Zusammenfassung

Der Zusammenhang zwischen Stillen und späterem kindlichen Übergewicht steht momentan im Fokus des wissenschaftlichen Interesses. Seit dem Jahr 2000 wurden mehr als 20 Kohortenstudien mit unterschiedlichen Ergebnissen zu diesem Thema publiziert. Während kürzlich durchgeführte Metaanalysen einen zwar geringen, aber signifikanten protektiven Effekt des Stillens fanden, konnte zuletzt eine große Studie keinen solchen Effekt nachweisen. Ziel dieses Beitrages ist es, Stärken und Limitationen einer Metaanalyse anhand der Ergebnisse einer ausgewählten Arbeit exemplarisch zu diskutieren.

Abstract

The relationship between breast-feeding and childhood obesity is of great interest. Since 2000, several studies have been published with conflicting data regarding the potential protective effect of breast-feeding on childhood obesity. Meta-analyses suggested a small but significant protective effect of breast-feeding, but a recent study was not able to show such an effect. This paper summarises one of these meta-analyses and discusses the strengths and limitations of the meta-analysis approach.
