Guelph Family Health Study: pilot study of a home-based obesity prevention intervention.

ABSTRACT: OBJECTIVE:To examine the feasibility and preliminary impact of a home-based obesity prevention intervention among Canadian families. METHODS:Families with children 1.5-5 years of age were randomized to one of three groups: (1) four home visits (HV) with a health educator, emails, and mailed incentives (4HV; n?=?17); (2) two HV, emails, and mailed incentives (2HV; n?=?14); or (3) general health advice through emails (control; n?=?13). Parents randomized to the 2HV and 4HV groups completed post-intervention satisfaction surveys. At baseline and post-intervention, parents reported frequency of family meals and their children's fruit, vegetable, and sugar-sweetened beverage (SSB) intake. We assessed the children's physical activity, sedentary behaviour, and sleep using accelerometers and their % fat mass using bioelectrical impedance analysis. Differences in outcomes at post-intervention, controlling for baseline, were examined using generalized estimating equations. RESULTS:Of the 44 families enrolled, 42 (96%) had 6-month outcome data. Satisfaction with the intervention was high; 80% were "very satisfied" and 20% were "satisfied." At post-intervention, children randomized to the 4HV and 2HV groups had significantly higher fruit intake and children randomized to the 2HV group had significantly lower percentage of fat mass, as compared to the control. No significant intervention effect was found for frequency of family meals, the children's vegetable or SSB intake, physical activity, sedentary behaviour, or sleep. CONCLUSIONS:Our results suggest that the delivery of a home-based intervention is feasible among Canadian families and may lead to improved diet and weight outcomes among children. A full-scale trial is needed to test the effectiveness of this home-based intervention. CLINICAL TRIALS REGISTRATION NUMBER:NCT02223234.

Project description:Background:Home-based lifestyle behaviour interventions show promise for treating and preventing childhood obesity. According to family theories, engaging the entire family unit, including parents, to change their family behaviour and dynamics may be necessary to prevent the development of childhood obesity. However, little is known about how these interventions, which may change the family dynamics and weight-related behaviours of parents, affect weight outcomes in parents. Our objective was to examine the effect of a pilot home-based childhood obesity prevention intervention on measures of anthropometrics and body composition in Canadian parents. Methods:Forty-four families with children aged 1.5-5?years were randomized to one of three groups: 4 home visits with a health educator, emails, and mailed incentives (4?HV); 2 home visits, emails, and mailed incentives (2?HV); or general health emails (control). Both the 2?HV and 4?HV intervention were conducted over a period of 6?months. Body composition and anthropometric outcomes were measured at baseline and at 6?months and 18?months from baseline. Results:In parents with baseline body mass index (BMI)???25?kg/m2, the 2?HV group had significantly lower body mass and waist circumference at 6-month (CI = -5.85,-0.14 kg;-5.82,-0.30 respectively) and 18-month follow-up (CI?=?-7.57,-1.21?kg;-9.30,-2.50?cm respectively) when compared to control, and significantly lower BMI at 18-month follow-up when compared to control (CI?=?-2.59,-0.29?kg/m2). In parents with baseline BMI?<?25?kg/m2, the 4?HV group had significantly lower percentage fat mass (CI?=?-3.94,-0.12%), while the 2?HV group had significantly lower body mass (CI?=?-2.56,-0.42?kg) and BMI (CI?=?-0.77,-0.08?kg/m2) at 6-month follow-up, both compared to control; these effects were not maintained at 18-month follow-up. Conclusions:This study provides support that a home-based childhood obesity prevention intervention may improve weight outcomes among parents. Future research should explore how home-based interventions influence family behaviour and dynamics to impact weight outcomes in children and their parents. Trial registration:Prospectively registered August 2014, clinical trial identifier NCT02223234.

Project description:Objective:Community-based, family-centered obesity prevention/treatment initiatives have been shown to be effective in reducing body mass index (BMI) and improving healthy habits in children if implemented with high intensity and sufficient duration. Let's Go! 5-2-1-0 Program (5-2-1-0) was incorporated into family-centered, monthly physical activity classes and cooking classes over six months delivered by Young Men's Christian Association (YMCA) staff. We hypothesized that implementation of this intervention would improve 5-2-1-0 knowledge attainment, increase healthy behavior (based on 5- 2-1-0 curriculum), and improve BMI and waist circumference measurements in children. Methods:Children attending YMCA summer camps in Rochester, MN, during 2016 were recruited via study packets mailed to their families. Height, weight, and waist circumference measurements as well as the results of the Modified Healthy Habits Survey and the 5-2-1-0 Knowledge Acquisition Survey were recorded for each participating child at baseline and 6-month follow-up. The intervention group received monthly healthy habit reminder emails, and was invited to monthly evening cooking and physical activity classes for 7 sessions over a 6-month period. Results:Fifteen families in the intervention group attended classes. Of those, 13 families regularly participated in (attended at least 5 out of 7) both the monthly physical activity and cooking classes. The children in the intervention group had a significant improvement in the number of Knowledge Acquisition Survey questions answered correctly (p<0.001), while there was no improvement in the control group. As compared to children in the control group, there was no significant change in BMI or waist circumference or healthy habits in the intervention group. Conclusion:Our study findings indicate that our intervention resulted in improved knowledge about healthy habits, but did not significantly impact healthy habits or BMI. Potential reasons for this were the small sample size and the attenuated length and/or intensity of the intervention.

Project description:The Healthy Homes/Healthy Kids Preschool (HHHK-Preschool) pilot program is an obesity prevention intervention integrating pediatric care provider counseling and a phone-based program to prevent unhealthy weight gain among 2- to 4-year-old children at risk for obesity (BMI percentile between the 50th and 85th percentile and at least one overweight parent) or currently overweight (85th percentile ? BMI < 95th percentile). The aim of this randomized, controlled pilot study was to evaluate the feasibility, acceptability, and potential efficacy of the HHHK-Preschool intervention.Sixty parent-child dyads recruited from pediatric primary care clinics were randomized to: (1) the Busy Bodies/Better Bites Obesity Prevention Arm or the (2) Healthy Tots/Safe Spots safety/injury prevention Contact Control Arm. Baseline and 6-month data were collected, including measured height and weight, accelerometry, previous day dietary recalls, and parent surveys. Intervention process data (e.g., call completion) were also collected.High intervention completion and satisfaction rates were observed. Although a statistically significant time by treatment interaction was not observed for BMI percentile or BMI z-score, post-hoc examination of baseline weight status as a moderator of treatment outcome showed that the Busy Bodies/Better Bites obesity prevention intervention appeared to be effective among children who were in the overweight category at baseline relative to those who were categorized as at risk for obesity (p?=?0.04).HHHK-Preschool pilot study results support the feasibility, acceptability, and potential efficacy in already overweight children of a pediatric primary care-based obesity prevention intervention integrating brief provider counseling and parent-targeted phone coaching. What's New: Implementing pediatric primary care-based obesity interventions is challenging. Previous interventions have primarily involved in-person sessions, a barrier to sustained parent involvement. HHHK-preschool pilot study results suggest that integrating brief provider counseling and parent-targeted phone coaching is a promising approach.
