Introduction: Lifestyle modification, such as healthy diet habits, regular physical activity, and maintaining a normal body weight, must be prescribed to all hypertensive individuals. This study aims to test whether a multicomponent intervention is effective in improving lifestyle and body weight among low-income families. Study design: Cluster randomized trial conducted between June 2013 and October 2016. Setting/participants: A total of 1,954 uninsured adult patients were recruited in the study within 18 public primary healthcare centers of Argentina. Intervention: Components targeting the healthcare system, providers, and family groups were delivered by community health workers; tailored text messages were sent for 18 months. Main outcome measures: Changes in the proportion of behavioral risk factors and body weight from baseline to end of follow-up. Data were analyzed in 2017. Results: Low fruit and vegetable consumption (fewer than 5 servings per day) decreased from 96.4% at baseline to 92.6% at 18 months in the intervention group, whereas in the control group it increased from 97.0% to 99.9% (p=0.0110). The proportion of low physical activity (
