Association of Revised WIC Food Package With Perinatal and Birth Outcomes: A Quasi-Experimental Study.

ABSTRACT:

Importance

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) serves more than one-quarter of pregnant and postpartum women. In October 2009, the WIC food package underwent revisions to improve nutritional content. No studies have investigated the downstream effects of this revision on maternal and infant health.

Objective

To investigate whether the revised WIC food package improved perinatal and birth outcomes among recipients.

Design, setting, and participants

We conducted a quasi-experimental difference-in-differences analysis, comparing WIC recipients (the treatment group) before and after the package revisions while accounting for temporal trends among nonrecipients (the control group). Multivariable linear regressions were adjusted
