Brief Summary

Despite numerous interventions designed to increase physical activity, few are specifically tailored to Latinas, a population where higher rates of obesity, diabetes, and other chronic diseases are present. This proposed smartphone app, ¡Caminemos Juntas!, will use location-based services to connect Latinas with one another in order to improve walking habits by increasing social support and decreasing perceived barriers, both of which are known to play a role in physical activity behaviors. Through a randomized comparative-effectiveness trial, this Phase II project will test the effectiveness of a smartphone application for improving physical activity among Latinas when providing them with real-time opportunities to connect socially with the goal of walking.

Outcome Measures

Primary Outcomes (2)

• Change in Physical Activity at 4 Weeks

  The Community Healthy Activities Model Program for Seniors (CHAMPS) is a 41-item PA questionnaire that measures self-reported minutes-per-week of PA calculated as total weekly caloric expenditure for all PA. It was developed for underactive populations and validated among older adults. However, CHAMPS has been used with younger and racially/ethnically diverse populations; it is sensitive to change specifically in Latino and other populations including ones younger than senior age. The CHAMPS asks about activities undertaken for exercise, daily activities that are physical in nature, and physically active recreational activities during "a typical week in the past 4 weeks."

  0 weeks and 4 weeks

• Change in Physical Activity at 8 Weeks

  The Community Healthy Activities Model Program for Seniors (CHAMPS) is a 41-item physical questionnaire that measures self-reported minutes-per-week of physical activity calculated as total weekly caloric expenditure in all physical activity. Hours and minutes per week were assessed for different types of physical activity. Using body weight and minutes of physical activity (by type), total caloric expenditure was calculated. Data is presented as a T-score with higher values (positive) indicating more calories expended at 8 weeks compared to baseline. Range = 2.5-145.2 kilocalories/kg/hr in the World Walking App condition; range = 6.9-120.1 kilocalories/kg/hr in the Caminemos condition. This measure was administered at 8 weeks to measure changes in physical activity.
