Effectiveness of Theory-Based Physical Activity and Nutrition Interventions in Aging Latino Adults: A Scoping Review

In the United States (US), Latino individuals older than 50 years face health disparities compared to their White counterparts. Considering the rising life expectancy and the projected increase of older Latino adults in the US, this scoping review aimed to determine the effectiveness of theory-based and culturally relevant strategies that promote healthy aging in Latinos. Web of Science and PubMed databases were searched between December 2022 and February 2023 for peer-reviewed articles assessing healthy aging interventions tailored to community-dwelling aging Latino adults. We included nine studies describing the effects of seven interventions on physical activity- or nutrition-related outcomes. Although not always statistically significant, interventions had a beneficial impact on well-being indicators. The most commonly used behavioral theories were Social Cognitive Theory and Attribution Theory. Latino cultural elements in these studies included partnering with community organizations that serve Latinos (such as Catholic churches), delivery of in-person bilingual group sessions by trusted community members (such as promotoras or Latino dance instructors), and incorporating values such as family and religion into the health curriculum, among others. Future strategies that promote healthy aging in Latino adults should proactively culturally adapt the theoretical foundations and the design, recruitment, and implementation processes to ensure their relevance and effectiveness.
