[TigerKids. Successful health promotion in preschool settings]

Abstract

The high prevalence of childhood obesity necessitates broadly effective prevention measures. A behavioral program for children in daycare settings was developed, and its effects were assessed in a 2-year cluster randomized controlled trial. A total of 64 daycare settings were cluster randomized in a 2:1 ratio to intervention and control in order to assess the effects of the program. Samples of 1318 and 1340 children were assessed after 5.7±2.6 and 17.6±2.3 months. Main outcome measures were prevalence of high fruit and vegetable consumption and of low consumption of high caloric drinks at home assessed by parental questionnaires. TigerKids achieved a significantly higher prevalence of high home consumption of fruits (66.6 vs. 55.7%, p<0.0001) and vegetables (42.7 vs. 33.6%, p=0.001) as well as a lower frequency of high consumption of energy rich beverages (47.7 vs. 60.4%, p<0.0001). The TigerKids group tended to show a lower prevalence of overweight (13.9 vs. 18.0%, p=0.05) and obesity (3.4 vs. 5.4%, p=0.07) in the first year. TigerKids is a low cost program applied in daycare settings which achieves significant behavioral changes in the home environment.
