Impact of a Home-Based Obesity Prevention Intervention on Children's and Parents' BMI: Findings From the Guelph Family Health Study Randomised Controlled Trial.
Background: To prevent the development of obesity and related comorbidities, interventions must begin early in life. This study aimed to assess the impact of a home-based obesity prevention intervention on children's and parents' body mass index (BMI).
Methods: The Guelph Family Health Study is a randomised controlled trial of a 6-month obesity prevention intervention aimed at establishing healthful household routines regarding family meals, children's screen time, physical activity and sleep among 285 families with preschool-aged children. The control group received 6 emails on child health behaviours. The analytic sample included 376 children (3.6 ± 1.3 years old, 20.2% at risk for overweight, 8.2% with overweight/obesity) and 481 parents (58.2% with overweight/obesity).
Results: Compared to controls, the intervention had no significant impact on children's or parents' BMI at post-intervention and 1 year after the intervention. Children in both the intervention and control groups had a non-significant decrease in BMI from baseline to post-intervention [intervention; -0.23 kg/m2 (95% CI, -0.46, 0.002); control; -0.17 kg/m2 (95% CI, -0.40, 0.06)] and from baseline to 1-year follow-up [intervention, -0.29 kg/m2 (95% CI, -0.67, 0.08); control, -0.06 kg/m2 (95% CI, -0.42, 0.30)].
Conclusions: Compared to controls, this home-based obesity prevention intervention had no significant impact on children's or parents' BMI immediately after the intervention or after 1 year of follow-up, indicating that the intervention had no additional effect compared to the control group on children's or parents' BMI over time. Future data collection phases will allow for the examination of the intervention effect on BMI as children age.
Trial registration: This study is registered at clinicaltrial.gov identifier: NCT02939261.
期刊介绍：
Pediatric Obesity is a peer-reviewed, monthly journal devoted to research into obesity during childhood and adolescence. The topic is currently at the centre of intense interest in the scientific community, and is of increasing concern to health policy-makers and the public at large.
Pediatric Obesity has established itself as the leading journal for high quality papers in this field, including, but not limited to, the following:
Genetic, molecular, biochemical and physiological aspects of obesity – basic, applied and clinical studies relating to mechanisms of the development of obesity throughout the life course and the consequent effects of obesity on health outcomes
Metabolic consequences of child and adolescent obesity
Epidemiological and population-based studies of child and adolescent overweight and obesity
Measurement and diagnostic issues in assessing child and adolescent adiposity, physical activity and nutrition
Clinical management of children and adolescents with obesity including studies of treatment and prevention
Co-morbidities linked to child and adolescent obesity – mechanisms, assessment, and treatment
Life-cycle factors eg familial, intrauterine and developmental aspects of child and adolescent obesity
Nutrition security and the "double burden" of obesity and malnutrition
Health promotion strategies around the issues of obesity, nutrition and physical activity in children and adolescents
Community and public health measures to prevent overweight and obesity in children and adolescents.
