Brief fruit and vegetable messages integrated within a community physical activity program successfully change...

Area of Science:

• Public Health
• Health Behavior Change
• Nutrition Interventions

Background:

• Low fruit and vegetable intake is a public health concern, with less than 25% of Americans meeting daily recommendations.
• Effective behavior change strategies require theory-based approaches and community support.
• Existing health promotion programs offer a platform for integrating dietary interventions.

Purpose of the Study:

• To evaluate the effectiveness of a low-intensity, theory-based intervention to increase fruit and vegetable consumption.
• To assess the impact of a fruit and vegetable intervention (FVI) integrated into a community physical activity program.

Main Methods:

• A randomized controlled trial with 86 participants assigned to either the FVI or a standard control group.
• The FVI utilized social cognitive theory-based messages delivered via nine weekly newsletters.
• Participants were recruited from an existing community physical activity program.

Main Results:

• Participants in the FVI group increased daily fruit and vegetable intake by approximately 1 to 1.3 servings.
• No significant change in consumption was observed in the control group.
• Reading seven or more newsletters correlated with a two-serving daily increase, indicating dose-response relationship.

Conclusions:

• The FVI effectively improved fruit and vegetable consumption in adults.
• Minimalist interventions like newsletters can reach broad audiences and integrate into existing health programs.
• This approach holds significant potential for public health impact by promoting healthier diets.
