| Abstract: | BackgroundFood shopping frequency may be an important modifiable factor related to increasing fruit and vegetable (FV) intake. Because of mixed findings of individual studies of shopping frequency, a systematic review is needed to examine findings across studies and store types.ObjectiveTo conduct a systematic review of articles examining the relationship between frequency of food shopping and FV intake including examination of participation in federal nutrition assistance programs on FV intake, if reported.MethodsA search, guided by the Preferred Reported Items for Systematic Reviews and Metanalyses, using terms related to FV consumption and food shopping across 4 online databases, was conducted. Studies conducted in the US and published through October, 2020, included adults, and had a cross-sectional, longitudinal, cohort, or randomized study design were eligible for inclusion.ResultsTwenty-four articles were included. The majority of studies found at least 1 positive finding between the frequency of food shopping and FV intake, indicating that as the frequency of food shopping increased, FV intake increased. In studies with 100% participation in government/federal nutrition assistance programs, participation was associated with FV intake. Studies that included participation as a subset found participation not associated with FV intake.Implications for Future Research and PracticeThe frequency of shopping may be modifiable to increase FV intake. Experimental research is needed to test the directionality and causality of the relationship. Federal nutrition assistance programs may be a logical place to test the relationship through the adjustment of fund disbursements. |
