Article Synopsis
  • The WIC program enhances nutrition for low-income families by providing nutritious food, and in June 2021, it increased funding specifically for fruits and vegetables (FV).
  • An analysis of grocery transactions from 496 stores in North Carolina revealed that WIC participants increased their FV purchases by $12.4 per month after the funding boost, significantly more than non-WIC shoppers.
  • In addition to increased FV purchases, WIC shoppers also bought more processed foods and sugary beverages, indicating a need for further research on the overall impact of these funding changes on dietary habits.

Background: More than one-third of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participants identify as Latino, but participation has been declining and individuals who speak predominantly Spanish face additional barriers to participation. During the COVID-19 pandemic, there were changes in WIC eligibility and benefits that may have been differentially accessible to Spanish-speaking Latina participants due to factors such as language barriers and lack of awareness of changes. Understanding Spanish-speaking Latinas' experiences with the WIC program generally and during the pandemic can inform efforts to equitably implement future emergency food response policies and improve the WIC program and Latina participant enrollment more broadly.

Background: Families participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) experienced barriers to accessing healthy food during the COVID-19 pandemic, but we do not yet understand how WIC participant food purchases shifted during the pandemic.

Objectives: We aimed to describe the association between the initial shock of the pandemic in March 2020 and WIC shoppers' food purchases and changes in purchases before and during the pandemic at a top grocery chain and examine differences in these relationships by duration of WIC use.

Methods: We used longitudinal food transaction data from WIC shoppers ( = 2,989,116 shopper-month observations from 175,081 unique WIC shoppers) from 496 stores in a top grocery store chain in North Carolina between October 2019 and May 2021.

Bacterial vaginosis (BV), a dysbiosis of the vaginal microbiota, is a common coinfection with (Ct), and BV-associated bacteria (BVAB) and their products have been implicated in aiding Ct evade natural immunity. Here, we determined if a non-optimal vaginal microbiota was associated with a higher genital Ct burden and if metronidazole, a standard treatment for BV, would reduce Ct burden or aid in natural clearance of Ct infection. Cervicovaginal samples were collected from women at enrollment and, if testing positive for Ct infection, at a follow-up visit approximately one week later.
