Project Summary/Abstract Physical inactivity and poor diet quality, including low fruit and vegetable consumption and high sugar- sweetened beverages, have been linked with diabetes, overweight/obesity and numerous chronic health conditions. For Latina women in the U.S., the disproportionately low physical activity (PA) levels and unhealthy dietary habits contribute to the high and rising prevalence of diabetes and overweight/obesity, as well as heart disease, hypertension, and stroke. Reducing these disparities requires culturally appropriate interventions that promote multiple health behaviors of PA and healthy eating. The majority of lifestyle interventions that target these behaviors in Latinos have been implemented using face-to-face approaches, which may not be accessible to Latinas due to common barriers (e.g., lack of time, fear of immigration enforcement, and lack of transportation) and can require costly resources to implement. Internet-based interventions can overcome barriers of face-to-face approaches and have potential for wide reach. Latinos now report higher Internet usage than White and Black adults (95% Latinos use Internet) and are more likely than non-Latinos to use their mobile devices to access health information. While most Latinas report more than one modifiable risk factor contributing to cardiometabolic disease (physical inactivity, poor diet quality) no Internet-based interventions have yet been developed that are culturally tailored to address both diet and PA needs of Latinas. Our research team has already developed and tested a culturally and linguistically adapted, theory-driven, Internet- based intervention promoting PA in Latina women, Pasos Hacia la Salud, that has shown success by increasing and maintaining PA gains in this population over 12 months. Latina participants in our team’s PA studies have also expressed interest in learning more about dietary quality. Thus, we will expand our Internet- based PA intervention to include promotion of healthy eating in Latinas as a more comprehensive approach to reducing cardiometabolic disease in Latinas. We will then test the preliminary efficacy of the adapted web- based multiple behavior change intervention for Latinas in a 12-week pilot RCT. Participants (N=70) will be randomized to: 1) PA and dietary intervention arm, or 2) wait-list control arm. The goal of the proposed study is to help Latinas meet national PA and dietary guidelines for F&V and SSB consumption. This work leverages our existing infrastructure (web-based platform), didactic training, and the unique and complementary expertise of the mentorship team and collaborators in developing innovative technology-based and individually tailored PA and diet interventions in at-risk populations. The proposed project will provide the PI (Dr. Benitez) training on nutrition research and new methodologies in this area (Intervention Mapping process, evaluation of nutrition interventions, and multiple behavior clinical trials). This study proposes a novel, low-cost and high reach approach to reduce the burden of cardiometabolic disease in Latinas and will provide the PI with skills for developing and conducting culturally tailored multiple behavior (nutrition and physical activity) clinical trials.
