Using web-based technology to promote physical activity in Latinas: Results of the Muévete Alabama pilot study

摘要

Latinas in the U.S. report high levels of physical inactivity and are disproprotionally burdened by related health conditions (ex., Type 2 Diabetes, obesity), highlighting the need for innovative strategies to reduce these disparities. A one-month single-arm pre-posttest design was utilized to assess the feasibility and acceptability of a culturally and linguistically adapted Internet-based physical activity intervention for Spanish-speaking Latinas. The intervention was based on the Social Cognitive Theory and the Transtheoretical Model. Changes in physical activity and related psychosocial variables were measured at baseline and the end of the one-month intervention. The sample included 24 Latina adults (mean age= 35.17±11.22). Most (83.3%) were born outside of the continental United States. Intent-to-treat analyses showed a significant increase (p= .001) in self-reported moderate-to-vigorous intensity physical activity from a median of 12.5 minutes per week at baseline to 67.5 minutes per week at the one-month assessment. Participants reported significant increases in self-efficacy as well as cognitive and behavioral processes of change. Nearly half (45.8%) of the participants reported advancing at least one stage of change during the course of the one-month intervention. Findings support the feasibility and acceptability of using interactive Internet-based technology to promote physical activity among Latinas in Alabama.
