Purpose: The Guelph Family Health Study (GFHS) pilot was designed to examine the feasibility and effectiveness of a home-based obesity prevention intervention on health behaviours and obesity risk. The objective of this analysis was to determine the effect of the 6-month intervention on preschool-aged children’s dietary intakes.
Methods: Families with children aged 1.5–5 years old were randomized to receive one of the following: 4 home visits with a health educator as well as tailored emails and mailed incentives (4HV; n = 19 children); 2 home visits with a health educator as well as tailored emails and mailed incentives (2HV; n = 14 children); or general health advice through emails (control; n = 12 children). Three-day food records were completed by parents for their children before and after the 6-month intervention and analyzed for 3-day average intakes of energy, nutrients, and MyPlate food groups.
Results: After the 6-month intervention, the 4HV group had significantly higher fibre intake and the 4HV and 2HV groups had significantly higher fruit intake, both compared with the control group.
Conclusions: This study provides support for a home-based intervention approach to improve the diet quality of preschool-aged children.
