This review synthesizes findings from studies examining the effects of health care–based interventions designed to reduce FI.METHODS We conducted a systematic review of peer-reviewed literature published from January 2000 through September 2018 that described health care– based FI interventions. Standardized mean differences (SMD) were calculated and pooled when appropriate. Study quality was rated using Grading Recommendations Assessment Development and Evaluation criteria.RESULTS Twenty-three studies met the inclusion criteria and examined a range of FI interventions and outcomes. Based on study design and sample size, 74% were rated low or very low quality. Studies of referral-based interventions reported moderate increases in patient food program referrals (SMD = 0.67, 95% CI, 0.36-0.98; SMD = 1.42, 95% CI, 0.76-2.08) and resource use (pooled SMD = 0.54, 95% CI, 0.31-0.78). Studies describing interventions providing food or vouchers reported mixed results for the actual change in fruit/vegetable intake, averaging to no impact when pooled (–0.03, 95% CI, –0.66 to 0.61). Few studies evaluated health or utilization outcomes; these generally reported small but positive effects.CONCLUSIONS Although a growing base of literature explores health care–based FI interventions, the low number and low quality of studies limit inferences about their effectiveness. More rigorous evaluation of FI interventions that includes health and utilization outcomes is needed to better understand roles for the health care sector in addressing FI. ER -
