Intervention Effects on Latinas' Physical Activity and Other Health Indicators.

INTRODUCTION: U.S. Latinas do not engage in sufficient leisure-time physical activity. This study examined whether adding promotor-facilitated healthy lifestyle classes to an exercise intervention would promote exercise session attendance and improve health indicators. METHODS: The Familias Sanas y Activas II (Healthy and Active Families II) study used a within-subjects, longitudinal design, with measures at baseline and at 6 and 12 months post-baseline. The intervention was developed by the San Diego Prevention Research Center and implemented between May 2011 and June 2014 in South San Diego County. Three organizations each hired a part-time coordinator and trained volunteer promotores (six to ten per organization) to deliver the intervention in various community locations. A convenience sample of 442 Latinas were in the evaluation cohort. Measured variables included a step test, blood pressure, waist circumference, height, and weight; physical activity was self-reported. RESULTS: Attendance at healthy lifestyle classes was positively associated with exercise session attendance (p≤0.001). Mixed effects models showed improvements in systolic and diastolic blood pressure (p≤0.001); waist circumference (p≤0.001); weight (p≤0.05); and BMI (p≤0.05) between baseline and 12 months. At 12 months, fewer participants met clinical guidelines for being hypertensive and having an at-risk waist circumference. Exercise session attendance was associated with improved fitness (p≤0.05) and increased self-reported MET minutes of leisure-time physical activity (p≤0.01). CONCLUSIONS: The intervention represents an effective strategy for improving the health status of Latinas, a population with significant health disparities, including high obesity rates. Research efforts are needed to assess methods for scaling up such interventions.

Community health partnerships for chronic disease prevention among Latinos: the San Diego Prevention Research Center.

Over 20 years ago, university-community partnerships (i.e., Prevention Research Centers [PRCs]) across the United States were funded by the Centers for Disease Control and Prevention to conduct research and training in order to promote health and prevent disease in underserved populations. In 2004, the San Diego PRC (SDPRC) became the first PRC to focus on obesity prevention and control in a community of mostly Mexican Americans/Mexican immigrants. The SDPRC was also the first PRC to comprise a university-community partnership with a school of public health, a school of medicine, and a federally qualified health center. In conjunction with two additional funded community partners and involvement of a community advisory board, the SDPRC seeks to develop effective intervention strategies that ultimately lead to behavior change. Now in its second cycle of funding, the SDPRC has identified three primary principles that are important for these and similar efforts: (1) developing culturally appropriate interventions requires community engagement; (2) building the evidence in a systematic and rigorous way yields meaningful strategies for translation to practice; and (3) translating evidence-based interventions to practice involves capacity building for both researchers and community partners. This article describes these principles to help others involved in similar intervention efforts identify the best approach for promoting health in their own communities.
