Lessons Learned From a Feasibility Study Delivered in 2 WIC Sites to Promote Physical Activity Among Pregnant Latinas

To assess the feasibility, including demand for and acceptability of a physical activity (PA) intervention among pregnant Latinas recruited at the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).

Women <20 weeks gestation and self-reporting <150 minutes of PA/wk were recruited from 2 WIC locations in Southern California. The 9-wk, promotora-led intervention included 1-hour sessions and 2 walking groups/wk.

WIC was supportive of recruitment, intervention, and evaluation activities. Of an estimated pool of 525 women at <20 wks gestation, 141 expressed interest, 108 were screened for eligibility, and 21 were enrolled. Of the 21 who enrolled, 12 completed the postintervention assessment (7 in the participant group and 5 in the nonparticipant group).

Demand and acceptability will need to be improved before this intervention can be considered feasible, potentially by extending eligibility and improving access to intervention.
