Increased WIC Cash Value Benefit is Associated with Greater Amount and Diversity of Redeemed Fruits and Vegetables among Participating Households.

Background: Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food packages for children ages 1 to 4 y include a cash value benefit (CVB) redeemable for fruits and vegetables (FVs) with participating vendors. The CVB value was increased beginning in June 2021.
Objectives: This study evaluated associations of the augmented CVB with the amount and diversity of redeemed FVs.
Methods: Price look-up codes (PLUs) in redemption data determined outcomes including any redemption (any, none), amount redeemed (United States dollars [USD]/mo), and percent of total CVB redemption (percent) in 54 FV commodity groups among a cohort of 1770 WIC-participating children in Southern California. Outcomes across all commodity groups for fresh fruits, fresh vegetables, and all FVs were evaluated including dollar amount redeemed , percentage of redemption , and diversity of produce redeemed (variety and balance among items redeemed). Comparisons were made between augmented CVB periods (35 USD/mo in June-September 2021, 24 USD/mo October 2021-June 2022) and the preaugment period (9 USD/mo in June 2020-May 2021). Associations were tested in multivariable generalized estimating equation Poisson (any redemption) and linear (amount, percent, diversity) regression models.
Results: The augmented CVB was associated with higher any redemption prevalence and amount redeemed for 53 of 54 commodity groups at both 35 USD/mo and 24 USD/mo compared with 9 USD/mo. Redemption diversity increased for both fruits, vegetables, and all produce during both augment periods, and modestly greater increases in redeemed fruits relative to vegetables were observed at 35 USD/mo. The most commonly redeemed vegetables were tomatoes, onions, cucumbers, peppers, and avocados and the most commonly redeemed fruits were bananas, apples, grapes, limes, and melons.
Conclusions: The augmented CVB was associated with greater redeemed FV amount and greater redeemed FV diversity. Data on FV intake diversity among WIC-participating children are needed to understand dietary impacts of the CVB increase.
