CHOKing Prevention Project

The aim of such study is to compare three different school-based (in nurseries, kindergartens and primary schools) interventions aimed at teaching to families how to prevent food choking injuries.

The topic of food choking primary and secondary prevention is placed in a more general topic regarding food safety, including education on food labeling and on food waste prevention.

The CHOP has been designed as a community intervention trial that compares three different school-based intervention strategies aimed at teaching to families how to prevent food choking injuries in children, together with the basics of food safety. The choice of employing such study design is motivated by the facts that community intervention trials allow to reach as many people as possible regardless their risk of experiencing the outcome of interest and to inform policy-makers on the effectiveness of an intervention on a community basis instead of an individual basis.

Forty-eight educational facilities (nurseries, kindergartens and primary schools) equally distributed between North, Centre, South, and major Islands of Italy will be enrolled.

Educational facilities will be stratified so that each stratum will include one educational facility from each educational stage (stratum=1 nursery, 1 kindergarten, 1 primary school).

The assessment of the effectiveness of each intervention strategy will be performed through a structured telephonic interview one month after the delivery of the intervention. I
