Reminder system for health screening in early childhood - an analysis regarding different social circumstances.

Background: Children with a low socio-economic position (SEP) participate in prevention and health examinations less often. In order to increase participation, reminder systems have been implemented in Germany since 2009. The aim of the study is to investigate whether this implementation is associated with an increased participation in health examination in early childhood for children in disadvantaged social circumstances.

Neighbourhood deprivation and obesity among 5656 pre-school children-findings from mandatory school enrollment examinations.

The risk of child obesity is strongly related to socioeconomic factors such as individual socioeconomic position (SEP) and neighbourhood deprivation. The present study analyses whether the relationship between neighbourhood deprivation and child obesity differs by child's individual SEP. Data from 5656 children (5-7 years) from the mandatory school enrollment examinations of the pre-school cohorts 2017/2018 in Düsseldorf were analysed.

[Is the school entrance examination a door opener for health sciences research? : Analyzing study participation of hard-to-reach groups].

Background: Additional scientific surveys within the compulsory school entrance examination (SEE) have become increasingly popular, partly because the SEE potentially reaches all socioeconomic groups. However, it has not been sufficiently explored whether selective participation in voluntary supplementary surveys actually results in no selection bias along socioeconomic characteristics. Therefore, the aim of this study is to analyze the participation of potentially hard-to-reach families in a parent survey at the SEE.
