Impact of worksite cafeteria interventions on fruit and vegetable consumption in adults: a systematic review

International Journal of Workplace Health Management,Volume 10, Issue 2, April 2017. Purpose Increasing obesity rates and health care costs have prompted worksites to investigate interventions to improve employee health. The purpose of this systematic review is to determine the effect of worksite cafeteria interventions on fruit and vegetable (F/V) consumption. Design/methodology/approach This review was guided by the PRISMA method. After a thorough literature search and screening process, 18 studies were included in the review. Data was extracted, and a risk of bias assessment was created for the primary studies. An un-weighted average was used to determine the overall ranking for each study. Findings There appears to be a moderately-strong association toward a positive impact of cafeteria interventions to increase F/V consumption. Of the 18 studies in the review, 13 reported a statistically significant increase, one reported a significant decrease, three reported mixed results, and one did not assess a change in consumption. Research limitations/implications Much of the data was self-reported and is subject to error. Furthermore, the heterogeneity of study design, method and outcome measures among the studies warrants additional research with consistent methodology. Practical implications A positive impact on F/V consumption may be realized by the following techniques: price-point subsidies, point-of-purchase materials, and menu modification. Originality/value This ne...
