Summary, Etc.  

요약The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is a federal nutrition assistance program that provides access to nutritious food, nutrition and breastfeeding education, and health care and social service referrals to more than six million families in the US, including more than 260,000 North Carolina families. To address the drastic increases in food insecurity during the COVID-19 pandemic, WIC increased the amount of money available to participants for fruits and vegetables by about $25/person/month through the Cash Value Benefit (CVB). Understanding how WIC participants' food purchases changed during the pandemic and in response to the CVB increase can inform WIC policy in emergency and non-emergency settings.Using longitudinal food transaction data from a large grocery store chain in North Carolina, we examined WIC shoppers' food purchases before and after the shock of the pandemic. We then used longitudinal food transaction data and focus groups with WIC participants in North Carolina to estimate the effects of the CVB increase on WIC households' fruit and vegetable purchases.After the pandemic, we observed increases in total calories purchased per day from all food categories examined, small decreases in the share (%) of total calories purchased from fruits and vegetables, and small increases in the share of total calories purchased from processed foods and sugar-sweetened beverages (SSBs) among WIC shoppers. After the CVB increase, WIC shoppers purchased a larger quantity and variety of fruits and vegetables compared to non-WIC shoppers. WIC participants had positive perceptions of the CVB increase, but experienced some challenges redeeming CVB benefits, and many felt they needed more than the increased CVB amount to meet their family's needs.Policies such as healthy food incentives and expanded access to nutrition assistance programs may be important in providing access to FV and other nutrient-dense foods in future public health emergencies. This study also provides important and timely evidence of the effectiveness of the CVB increase in improving WIC participant fruit and vegetable purchases and satisfaction with the foods provided by WIC that can inform improvements to the foods provided by WIC in non-emergency settings.
