Smoking Cessation Intervention in Public Housing
Keywords
Abstract
Description
This was a cluster randomized controlled study evaluating the effect of a multi-level intervention, Sister to Sister, on the smoking cessation in two Southeastern US metropolitan areas. Fourteen subsidized housing neighborhoods, eight in Charleston, SC and six in Augusta, GA, were pair matched based on size; with one neighborhood in each pair randomized to the intervention to ensure balanced recruitment between groups. Neighborhoods ranged in size from 22 to 33 participants with a total sample size of 409 women; neighborhoods were chosen as the primary sampling unit to prevent contamination of the outcome within neighborhoods, with women in the neighborhoods as secondary sampling unit. All statistical analyses were conducted using SAS 9.2 (SAS Institute, Cary, NC) with statistical significance at an alpha level of 0.05. Comparison between groups at baseline used t-tests for continuous variables and chi-square tests for categorical variables. The primary outcome of interest was smoking status which was dichotomized (smoker/non-smoker) at the 6 and 12 month measurements. Smoking status was determined by cotinine levels in saliva with non-smokers defined as those with cotinine levels of 14 ng/mL or less.

Arm Groups
| Arm | Intervention/treatment |
|---|---|
| Active Comparator: Delayed Control Women in the delayed control condition received culturally sensitive smoking cessation written materials at week 1, and mailed materials at week 6, 12, and 18. At the end of the study (i.e., after the 12 month data collection), participants were offered counseling, nicotine patches, and community health worker contacts. | Behavioral: Delayed Control Written Cessation Materials |
| Experimental: Experimental Women in neighborhoods randomized to the S2S received 24-week bundled multi-level intervention. Individual-led strategies were led by paid community health workers (CHWs). The CHWs provided 1:1 contact to reinforce social support, and enhanced self-efficacy with cessation attempts. A certified smoking cessation counselor led behavioral group sessions using the S2S handbook based on the PHS Guidelines. The weekly group sessions were initiated during the 1st week of the intervention, with a total of 6 group sessions over a 6-week period. Transdermal nicotine patches were offered to participants who set a quit date. Within the 24-week study period, the neighborhood tenant association, in partnership with study staff, implemented at least two neighborhood level anti-smoking activities | Behavioral: Experimental Neighborhood level interventions, peer group (counseling, NRT), and individual level (Coach/CHW) |
