Abstract: The purpose of this study was to explore the association between a home-based childhood obesity prevention intervention and preschooler body composition. The family-based intervention focused on the following obesity-related health behaviours: family meals, physical activity, screen time, sugar-sweetened beverage consumption, and sleep routines. Baseline and six-month follow-up data were collected from 42 families participating in the family-based obesity prevention intervention, the Guelph Family Health Study. Families were randomized into a two or four home visit group, or control group. Families randomized into the intervention groups received two or four home visits from a health educator, tailored weekly e-mails and mailed resources. The intervention was based on Motivational Interviewing counseling techniques. The majority of participants identified as Caucasian and were aged 18 months to 5 years. Using the World Health Organization (WHO) growth charts, 67.3% and 71.7% of children were classified as normal weight at baseline and six-month follow-up, respectively. At baseline, 3.9% of preschoolers were classified as overweight and this increased to 5.7% at six-month follow-up. No participants were classified as obese. The intervention was found to be associated with improved body composition outcomes for total body water for the two home visit and combined intervention groups, and for fat mass (% and kg) for the two home visit group. The intervention showed no significant associations with body composition measures for the four home visit group. The findings from this study suggest that a smaller intervention dose may be appropriate to achieve favourable changes in body composition and weight status. This study provides insight into how a family-based obesity prevention intervention in the home setting combined with MI counseling techniques can impact preschooler body composition outcomes.
