Clinical Trial Summary

Comprehensive smoke-free policies have the potential to substantially reduce tobacco-related disparities among populations in subsidized housing. This study fills this gap by identifying approaches to increase the implementation of smoke-free policies in all types of subsidized housing by increasing the voluntary adoption of smoke-free homes and promoting access to smoking cessation services.

Description:

OBJECTIVES:

The investigators will build on previous studies, where a smoke-free home intervention to increase voluntary adoption of smoke-free homes in permanent supportive housing for formerly homeless adults was developed and evaluated.

Aim 1: To estimate the effect of our adapted smoke-free home intervention on the primary outcome of residents' voluntary adoption of smoke-free homes and the secondary outcome of biochemically-verified tobacco abstinence at 6-months follow-up.

Aim 2: To determine the cost of our adapted smoke-free home intervention and determine whether it is a cost-effective use of health care resources.

Aim 3: To evaluate variation in stakeholders' perspectives on the adapted smoke-free home intervention's adaptability, scalability and sustainability.The proposed intervention can expand access to smoke-free policies and smoking cessation services in subsidized housing, thereby reducing racial/ethnic disparities in tobacco use, tobacco exposure and chronic disease in these populations.

OUTLINE:

A wait-list cluster randomized controlled trial of the adapted smoke-free home intervention compared to usual care among residents from subsidized housing sites in Northern California. Participants from twenty-four subsidized housing sites will be randomized into intervention and waitlist control arms
