Development of Novel Behavioral Intervention for Sustainable Weight Loss in Hispanic Adults With Obesity

Stopped early · Not applicable

Conditions studied: Obesity

In brief

There are great disparities in the prevalence of obesity and chronic disease in different sociodemographic groups. US Hispanic adults, in particular, have a higher prevalence of obesity and chronic diseases than non-Hispanic whites. Population aging is also a major contributing factor to the high prevalence of chronic disease, and Hispanics already make up approximately 10% of the older population. Therefore, preventive measures are needed to reduce the burden of chronic disease risks for Hispanics. Current lifestyle interventions for weight management have been particularly ineffective in this population. The purpose of this pilot project is to develop a novel tailored lifestyle intervention for use by Hispanic older adults with obesity. The Healthy Weight for Living intervention has been validated among adults with mixed racial/ethnic backgrounds and has achieved clinically impactful weight-loss. Its design features make it particularly suitable for use in populations with low adherence to traditional interventions, including no requirement for daily food logging and no increase in physical activity. The final product of this project will be a culturally adapted prototype intervention in Hispanic older adults that accounts for cultural heterogeneity. This work has direct relevance to reducing health disparities and the burden of obesity-associated chronic disease in a particularly at-risk population.
