Abstract

Introduction: Multiple aspects of the home food environment shape dietary patterns. The purpose of this study was to test a more scalable version of an intervention designed to promote healthy eating by improving home food environments, and to determine its cost-effectiveness.

Study design: A randomized controlled trial was conducted with follow-up at four and nine-months post-baseline (2020-2023).

Settings/participants: Participants were clients of four United Way 2-1-1 information and referral organizations in Georgia.

Intervention: Healthy Homes/Healthy Families is a three-month program alternating weekly coaching calls and text messages to encourage healthy eating by creating healthier home food environment through eight healthy actions.

Main outcome measures: The Healthy Eating Index (HEI-2015) was calculated from two 24-hour dietary food recalls. Data were analyzed in 2023-2024.

Results: The majority of participants (n=510) were women (91.6%) and identified as African American or Black (82.7%). The HEI-2015 improved more (3.26 units, p=.005) for the intervention than control group at nine-months in intent-to-treat analyses. Both total fruits (0.53, p=.009) and added sugar (0.81, p=.004) HEI-2015 domain scores also improved significantly. Multiple aspects of the home food environment improved in a desired direction, including inventories of unhealthy snacks/foods, food preparation and food serving practices, family meals from non-home food sources, and frequency of family meals and snacks while watching TV. Costs averaged $85 per participant ($95 for full program delivery); costs per unit HEI increase were $26. The intervention is cost-effective, with a cost per quality-adjusted life year of $28,762. The intervention is cost-saving as long as the benefits last three years or longer.

Conclusion: The intervention was effective in promoting modest changes in diet quality by improving home food environments.

期刊介绍： The American Journal of Preventive Medicine is the official journal of the American College of Preventive Medicine and the Association for Prevention Teaching and Research. It publishes articles in the areas of prevention research, teaching, practice and policy. Original research is published on interventions aimed at the prevention of chronic and acute disease and the promotion of individual and community health. Of particular emphasis are papers that address the primary and secondary prevention of important clinical, behavioral and public health issues such as injury and violence, infectious disease, women''s health, smoking, sedentary behaviors and physical activity, nutrition, diabetes, obesity, and substance use disorders. Papers also address educational initiatives aimed at improving the ability of health professionals to provide effective clinical prevention and public health services. Papers on health services research pertinent to prevention and public health are also published. The journal also publishes official policy statements from the two co-sponsoring organizations, review articles, media reviews, and editorials. Finally, the journal periodically publishes supplements and special theme issues devoted to areas of current interest to the prevention community.
