Abstract
INTRODUCTION: Latinas report low rates of physical activity (PA) and are at risk for poor health outcomes. Language and literacy barriers impede access and utilization of PA-related resources. This study examined health literacy as a moderator on changes in moderate-to-vigorous physical activity (MVPA) in 196 Latinas enrolled in Seamos Saludables, a randomized-controlled trial of a 6-month culturally and linguistically adapted PA print intervention METHODS: Secondary analyses were conducted on demographics, acculturation and generation status, and health literacy (Newest Vital Sign). MVPA was determined by 7 day physical activity recall, assessed at baseline and 6 months. General linear models examined interaction effects between health literacy (HL), experimental condition (treatment vs. control), and generation status. RESULTS:Health literacy moderated change in MVPA from baseline to 6 months. The intervention effect was greater among first-generation Latinas with limited health literacy. DISCUSSION: Differences in health literacy level appear to influence MVPA outcomes. Formative research is recommended to ensure that materials are appropriate when developing print-based PA interventions, particularly among first-generation Latinas who are more likely to have limited health literacy.
