Supporting Smoke-Free Policy Compliance in Public Housing

Columbia University405 enrolled

Overview

This project seeks to determine the effectiveness of two types of interventions to reduce exposure to secondhand smoke in residential buildings. One intervention is geared toward all building residents (resident endorsement) and the other targets smokers (smoking reduction via relocation and reduction in personal smoking/cessation) with the goal of reducing personal smoking and secondhand smoke exposure.

Smoke-free housing policies in multi-unit housing are promising and increasingly widespread interventions to reduce smoking and secondhand smoke exposure. Little research has identified factors that improve compliance with smoke-free housing policies in low-income multi-unit housing and test corresponding solutions. The proposed randomized controlled trial (RCT) addresses key gaps in knowledge and capitalizes on key scientific opportunities by: 1) leveraging the federal mandate to ban smoking in a public housing system of more than sufficient size to conduct an adequately powered RCT; 2) expanding our understanding of smoke-free policy compliance beyond policy implementation by testing two novel treatments: a) in-residence smoking cessation and b) resident endorsement, while 3) addressing population and location-specific tobacco-related disparities. The investigators hypothesize that the relocation/cessation plus resident endorsement intervention will yield significantly larger reductions in personal smoking and secondhand smoke exposure, compared to standalone interventions and the standard approach.

Building Inclusion Criteria: * NYCHA buildings in Manhattan \& the Bronx (stratified evenly by borough) with more than 50 units, not undergoing major renovations. Building Exclusion Criteria: * Buildings in a borough that is not in Manhattan or the Bronx * Buildings smaller than 50 units * Buildings undergoing major renovations * Buildings that are or will be part of Rental Assistance Demonstration (RAD) or Permanent Affordability Commitment Together (PACT) * Buildings that are mixed finance * Buildings that are exclusively for elderly * Buildings that are privately managed * Buildings that have other research studies ongoing Participant Inclusion Criteria: * Recruit NYCHA residents via door knocking and lobby intercepts until we reach our targeted number per group (4 smokers, 4 non-smokers in each building). * Residents will be screened for smoking status. Both smokers and non-smokers to be recruited but only one participant- smoker or a non-smoker- will be recruited per apartment. * Smoking will be defined as those that report using a cigarette or other combustible tobacco product (e.g., little cigar, cigarillo) at least 5 days in the past month. Non-smokers include never smokers and former smokers who had quit 12 months ago or earlier. * Additional eligibility criteria include individuals above 18 years old living in the building at least 5 days/week and 9 months/year, not planning on moving in the next 2 years. Participant Exclusion Criteria: * Individuals with severe physical or mental medical conditions (i.e. cognitive disability) or other factors that could limit participation or ability to give informed consent in the study at baseline or during follow-ups. * Individuals who participated in the earlier focus groups. * Individuals who only smoke non-tobacco products (e.g., marijuana).

Outcomes

Primary Outcomes

Change in number of cigarettes smoked per day

Self-reported average number of cigarettes smoked per day among smokers

Time frame: Measured at baseline (in person interview), 3 months (phone interview) and 12 months (in person interview)

Change in salivary cotinine

Salivary cotinine (saliva collected as passive drool) will be measured for 25% of the sample among smokers and non-smokers alike

Time frame: At baseline and at the 12-month follow-up

Change in secondhand smoke exposure

Self-reported secondhand smoking exposure (hours of secondhand smoke exposure in the building in the past 7 days); among smokers \& non-smokers

Time frame: Measured at baseline (in person interview), 3 months (phone interview) and 12 months (in person interview)

Secondary Outcomes

Change in number of participants with successful quit attempts

Binary; whether smokers have successfully quit

Time frame: Measured at baseline (in person interview), 3 months (phone interview) and 12 months (in person interview)

Change in number of quit attempts

Mean number of quitting attempts among smokers

Time frame: Measured at baseline (in person interview), 3 months (phone interview) and 12 months (in person interview)

Change in number of participants with secondhand smoke observations

Binary; whether participant has observed someone smoking indoors in the building; among smokers \& non-smokers

Time frame: Ever observing someone smoking indoors within the past 7 days measured at baseline (in person interview), 3 months (phone interview) and 12 months (in person interview)
