Guelph Family Health Study: Full Study (GFHS)

September 18, 2018 updated by: Jess Haines, University of Guelph
The overall objective of this research is to test, among families with children age 2-5 years, the immediate and longer-term impacts of a home-based intervention to improve household routines associated with reduced obesity risk. The investigators primary hypothesis is that, compared to control, children in the intervention group will have lower BMI following the 6-month intervention period and 18-month follow-up period. The secondary outcomes are change in children's % body fat, waist circumference and obesity-related behaviours: sleep, activity, sedentary behaviour, family meals, and dietary intake. Although child outcomes are the focus of this evaluation, changing household routines may also improve parent behaviour; thus, the investigators will assess change in parent behaviours and weight outcomes. This study will also assess the cost-effectiveness of the intervention from a societal perspective.

Detailed Description

The overall objective of this research is to test, among families with children age 2-5 years, the immediate and longer-term impacts of a home-based intervention to improve household routines associated with reduced obesity risk. The primary hypothesis is that, compared to control, children in the intervention group will have lower BMI following the 6-month intervention period and 18-month follow-up period. The secondary outcomes are change in children's % body fat, waist circumference and obesity-related behaviours: sleep, activity, sedentary behaviour, family meals, and dietary intake. Although child outcomes are the focus of this evaluation, changing household routines may also improve parent behaviour; thus, the investigators will assess change in parent behaviours and weight outcomes. This study also assess the cost-effectiveness of the intervention from a societal perspective.

The investigators will randomly allocate 356 socio-economically diverse Ontario families to receive either: 1) 4 motivational coaching home visits, bi-weekly emails, and mailed behaviour supports (intervention group), or 2) Monthly emails with general health information (control group). Primary and secondary outcomes will be assessed at baseline, post-intervention (6-months), and 18-month follow-up, and data will be analyzed by intention to treat.

This study tests a novel and promising approach to obesity prevention - an approach that engages families at home, where they eat, play, and sleep. The interdisciplinary investigator team has partnered with parents and key knowledge users in public health and primary care to develop this intervention. As a result, this research could provide a sustainable model for early life obesity prevention, leading to long-term improvements in health and reduction in costs to the health system and society as a whole.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Child - change in BMI
Time Frame: Baseline, 6 Months and 18 Months
Trained staff will use standard practices to measure child height to the nearest 0.1 cm with a Shorrboard stadiometer and child weight to the nearest 0.1 kg using a Seca scale. BMI will be the ratio of weight (kg) to the square of standing height (m).
Baseline, 6 Months and 18 Months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Baseline, 6 Months, 18 Months
Cost-effectiveness of Intervention
Time Frame: Baseline, 6 Months, 18 Months
The cost effectiveness of the study intervention will be assessed from a societal perspective. The direct costs associated with the intervention will be assessed, as well as health services use and indirect patient costs for both intervention and control groups. Direct costs of the intervention will be estimated from process data collected during the intervention. Through surveys at post-intervention, data will also be collected on costs to families for participating in the intervention, including time spent on home visits and other time costs associated with implementing the intervention recommendations. Health services use will be collected from parents and from linkage with administrative datasets (Ontario Health Insurance Plan). Parents will also be asked to report indirect patient costs, including number of missed school/work days.
