Healthy Home Offerings Via the Mealtime Environment (HOME) Plus

Not Applicable

Completed

• Conditions: Obesity
• Interventions: Behavioral: HOME Plus intervention

• Registration Number: NCT01538615
• Lead Sponsor: University of Minnesota

Brief Summary

The goal of the proposed project is to see if an innovative family-based intervention can reduce childhood obesity by actively engaging the whole family in promoting healthy behaviors in the home. In additions, the project will also examine how the HOME Plus family intervention influences children's dietary intake, frequency of family meals, availability of healthy and unhealthy foods in the home and served at meals and snacks, and screen time (TV, game systems). The study will provide important information on strategies that families can use at home to prevent obesity.

Detailed Description

Childhood obesity is a serious public health problem with limited effective prevention strategies to date. Although previous nutrition and physical activity environmental approaches for obesity prevention show some promise, most studies have not shown reductions in excess weight gain. Moreover, few prevention studies significantly engage parents and focus on the home environment. To prevent childhood obesity it is essential to promote healthy behaviors in the home environment because parents are influential primary role models for healthy eating and sedentary behavior, and are gatekeepers for food and beverage availability and degree of inactivity within the home. Moreover, the home setting is where most of children's calories and energy dense foods are consumed and where children engage in much of their sedentary behavior, particularly screen time (e.g., television, computer, game system). The proposed study will test the efficacy of the Healthy Home Offerings via the Mealtime Environment (HOME) Plus program, a ten-month, family-based health promotion intervention to prevent excess weight gain among 8-12 year old children. The program is based on Social Cognitive Theory and a socio-ecological framework and promotes both regular and nutritionally-sound snacks and meals in which family members eat together (i.e., family meals) and encourages reductions in sedentary behavior, particularly screen time among children in the home setting. The efficacy of the intervention will be tested in a randomized controlled trial with 160 families randomized to two conditions (intervention or attention-only control). Two cohorts of families, recruited from after-school programs and community centers, will be followed for 2.5 years. The primary hypothesis is that, by the end of the ten month intervention, target children in the intervention families, relative to children in the control families, will have significantly lower body mass index (BMI; primary outcome) after adjustment for baseline BMI values. Secondary outcomes include frequency of weekly family meals and number of healthful foods and beverages available in the home and served at family meals and snacks (as reported by parent), target children's daily intakes of healthful foods and beverages, and target children's minutes of sedentary behavior per week, particularly screen time. Child and parent measurement will occur in their homes at baseline, post-intervention (12-months post-randomization), and follow-up (9-months post-intervention) by trained research staff. The proposed study builds upon successful methods from our HOME pilot study (2006-2008; NIH R21-DK0072997) and is innovative as it actively engages entire families in experiential activities and capitalizes on the home setting. The study will provide important information on environmental and behavioral strategies that families can use at home to prevent excess weight gain. The intervention program has high translation potential and is likely to be immediately useful to families of school-age children because it will be tested in real-world community settings and sustained across the state of Minnesota by the University of Minnesota's Extension Service.

HOME Plus Intervention	HOME Plus intervention	described below

Primary Outcome Measures

Name	Time	Method
Change in Child Body Mass Index (BMI Z-score)	Change from Baseline at 12 and 21 months	Trained study staff will measure parent and child height and weight and use this to calculate body mass index (BMI). BMI values were than standardized for age and gender using CDC guidelines to obtain BMI z-scores. Analyses controlled for child age and parent education at baseline.

Secondary Outcome Measures

Name	Time	Method
Change in Target Children's Daily Intakes of Fruits and Vegetables	Change from Baseline at 12 and 21 months	A trained interviewer will complete three 24-hour dietary recalls at each data collection time point with the child. The three days will be averaged to get an estimate of usual intake. Analyses controlled for child age and parent education at baseline.
Change in Number of Fruits and Vegetables Available in the Home	Change from Baseline at 12 and 21 months	The HOME Food Inventory assesses which foods families currently have in their home from a list of items. Analyses controlled for child age and parent education.
Change in Target Children's Hours of Screen Time (Television Viewing, Video and Computer Game Playing) Per Week	Change from Baseline at 12 and 21 months	Screen time will be measured with survey questions asking children how many hours per day they spend doing each sedentary activity (such as watching TV, using the computer, playing video games). Separate questions will be asked for week days and weekend days then the will be weighted to determine the hours of sedentary activity per week. Analyses controlled for child age and parent education at baseline.
