Formative Research - Developing a Family-based Obesity Prevention Intervention in the Canadian Context

Study Overview
=================
Brief Summary
-----------------
This formative research shows that parents of preschool-aged children are enthusiastic about learning general parenting skills, such as discipline strategies, but that they are less interested in information on child nutrition and physical activity needs. To capitalize on this enthusiasm, Dr. Haines developed Parents and Tots Together (PTT), an intervention that embeds strategies to improve children's nutrition and activity behaviours within an existing general skills parenting program. Results from the investigators feasibility trial with 16 Boston-area parents show that PTT is feasible for implementation and is extremely well-received by parents. Results are also encouraging with respect to changing parent feeding behaviours and children's nutrition and activity behaviours. What is not known is whether this program is feasible and contextually appropriate for Canadian families. Thus, the next step in this research program, and the overall goal of this study, is to assess Parents and Tots Together (PTT), a family-based intervention to prevent obesity among children 3 to 5 years of age, within the Canadian context. To achieve this goal, the investigators will conduct a pilot trial of the PTT program with 60 families recruited through Ontario Early Years Centres (OEYC). The investigators will randomize 30 families to the 3-month PTT intervention and 30 to a control condition. The investigators primary objective is to implement and test the feasibility and acceptability of PTT among families with preschool children so appropriate revisions can be made to adapt it to a Canadian context. The investigators secondary objective is to compare the following outcomes among intervention versus control participants: Parent weight-related behaviours (i.e., parent physical activity, intake of sugar-sweetened beverages, and television/video viewing, as well as responsiveness to child satiety cues). General parenting behaviours (i.e., use of positive discipline strategies). Child weight-related behaviours (i.e., sleep duration, physical activity, intake of sugar-sweetened beverages, television/video viewing). Nutritional risk score based on a screening tool for preschoolers. Child change in body mass index (BMI), standardized to age and gender.
