The study is a controlled trial in the PRENSA network, which includes six urban practices serving a disadvantaged Latino population. Using data from a health risk assessment (HRA) routinely collected in PRENSA practices, medical assistants will assess 4500 patients' behavioral risks and apply behavior-specific "assess-advise-agree-assist-arrange" algorithms to engage behavioral interventions in the practices, health system, and local public health department. Outcomes data will be collected at 6-9 month follow-up with repeated completion of a standardized health risk assessment. The primary analyses will compare outcome measures for smoking, problem drinking, sedentary lifestyle, and unhealthy diet in intervention and control patients.
