The Child and Adult Care Food Program and young children's health: a systematic review.

Abstract

The Child and Adult Care Food Program (CACFP) is a federal nutrition program that supports young children's nutrition. Its potential impacts on child well-being have not been summarized. The objective of this review was to summarize the evidence for the impact of CACFP on children's diet quality, weight status, food insecurity, and cognitive development. Databases searched included MEDLINE, CAB Abstracts, Web of Science Core Collection, ERIC, PsycInfo, Dissertations & Theses Global (Proquest), EconLit, NBER, and the USDA's Economic Research Service (ERS), from database inception to November 12, 2021. Studies were included if the sample drew from child care programs serving children between the ages of 2years and 18years and if a comparison group of nonparticipating programs was included. Two reviewers independently extracted data on study design, year(s) of data collection, region, sample size, participant demographics, outcomes, and risk of bias. Due to the heterogeneity of the studies, a narrative synthesis was used. Nineteen articles were reviewed, most of which had been published since 2012. Seventeen used cross-sectional designs. Twelve evaluated foods and beverages served; 4 evaluated dietary intake; 4 evaluated the child care nutrition environment; 2 evaluated food insecurity, 1 evaluated weight status; none evaluated cognitive outcomes. Studies typically found either a small beneficial association with CACFP or no significant association. Currently, evidence for an association between CACFP and children's health is inconclusive, though it is slightly suggestive of a benefit for some dietary quality outcomes. More research, with stronger study designs, is needed. A protocol for this systematic review was registered with the PROSPERO systematic review protocol registry (PROSPERO 2021 CRD42021254423).
