Objective: The Resources for Health trial evaluates a social-ecologically based lifestyle (physical activity
and diet) intervention targeting low-income, largely Spanish-speaking patients with multiple chronic
conditions. Design: A randomized controlled trial was conducted with 200 patients recruited from an
urban community health center and assigned to intervention and usual care conditions. Intervention
involved 2 face-to-face, self-management support and community linkage sessions with a health
educator, 3 follow-up phone calls, and 3 tailored newsletters. Main Outcome Measures: Primary
outcomes measured at 6-months were changes in dietary behavior and physical activity. Changes in
multilevel support for healthy living were evaluated as a secondary outcome. Results: After adjustment
for age, sex, language, and number of chronic conditions, significant intervention effects were observed
for dietary behavior and multilevel support for healthy lifestyles but not for physical activity. Conclu-
sion: The Resources for Health intervention provides an effective and practical model for improving
health behavior among low-income, Spanish-speaking patients with multiple chronic conditions.
