The purpose of this study is to look at the best ways to prevent anxiety and depression in older Latino adults who are at risk for developing anxiety and depression. Participants will be randomized to either a health promotion intervention or a healthy lifestyles education program.

Given the prevalence and morbidity of depression in later life, the inadequacies of current treatment approaches for averting years living with disability, the inequities in access to the mental health care delivery system, and the workforce shortages to meet the mental health needs of older Latinos, development and testing of innovative strategies to prevent depression and anxiety are of great public health significance and have the potential to change practice.
