Internet access has grown markedly in Latinos during the past decade. However, there have been no Internet-based physical activity interventions designed for Latinos, despite large disparities in lifestyle-related conditions, such as obesity and diabetes, particularly in Latina women. In this study, Inactive Latinas (N = 205) were randomly assigned to either the Tailored Physical Activity Internet Intervention or the Wellness Contact Control Internet Group. Participants in both groups received emails on a tapered schedule over 6 months to alert them to new content on the website. The primary outcome was minutes/week of moderate to vigorous physical activity at six months as measured by the 7-Day Physical Activity Recall; activity was also measured by accelerometers. Data were collected between 2011 and 2014 and analyzed in 2015.
The study found that increases in minutes/week of moderate to vigorous physical activity were significantly greater in the Intervention Group compared to the Control Group. Increases in objectively measured moderate to vigorous physical activity were also significantly larger in the Intervention Group. The Intervention Group was also significantly more likely to meet national physical activity guidelines at six months. Findings from this study suggest that this Internet-delivered individually tailored intervention successfully increased moderate to vigorous physical activity in Latinas compared to a Wellness Contact Control Internet Group.
