Effect of a smoking cessation intervention for women in subsidized neighborhoods: A randomized controlled trial
Abstract
Objective To evaluate the effectiveness of a community based participatory research (CBPR) developed, multi-level smoking cessation intervention among women in subsidized housing neighborhoods in the Southeastern US. Methods A total of n = 409 women in 14 subsidized housing neighborhoods in Georgia and South Carolina participated in this group randomized controlled trial conducted from 2009 to 2013. Intervention neighborhoods received a 24-week intervention with 1:1 community health worker contact, behavioral peer group sessions, and nicotine replacement. Control neighborhoods received written cessation materials at weeks 1, 6, 12, 18. Random coefficient models were used to compare smoking abstinence outcomes at 6 and 12 months. Significance was set a p < 0.05. Results The majority of participants (91.2%) were retained during the 12-month intervention period. Smoking abstinence rates at 12 months for intervention vs. control were 9% vs. 4.3%, p = 0.05. Additional analyses accounting for passive smoke exposure in these multi-unit housing settings demonstrated 12 month abstinence rates of 12% vs. 5.3%, p = 0.016. However, in the multivariate regression analyses, there was no significant effect of the intervention on the odds of being a non-smoker (OR = 0.44, 95% CI: 0.18–1.07). Intervention participants who kept coach visits, attended group sessions, and used patches were more likely to remain abstinent. Conclusions This CBPR developed intervention showed potential to engage…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 409 participants or records.
