Impact of a Community-based Intervention on Serving and Intake of Vegetables among Low-income, Rural Appalachian Families

Abstract Objective To evaluate the effectiveness of a community-based intervention promoting the serving and eating of deep-orange, cruciferous, and dark-green leafy vegetables. Design Randomized, parallel-group, community-based intervention with a baseline/postintervention/3-month follow-up design. Setting and Participants Low-income food preparers (n = 50) and their partners (n = 50) in rural Appalachia Pennsylvania. Intervention Experimental food preparers attended 8 weekly interactive lessons; control food preparers received 8 weekly mailings that included similar recipes and handouts. Main Outcome Measures Target vegetable intake and frequency of serving by experimental and control treatment groups and by high and low meal diary scores, a measure of recipe acceptability. Analysis Linear mixed-model analysis with repeated measures. Results No significant differences resulted between the original experimental and control treatment groups. When grouped by high and low meal diary scores, more experimental families had high scores than in controls. High scores were associated with significant changes in frequency of serving and intake of the target vegetables. Conclusions and Implications Meal diary use may foster food preparer negotiation with partners and children to become involved in vegetable dish evaluation. Tools to help the trained food preparer draw family members into recipe evaluation, such as the meal diary, are useful and needed.
