Abstract
Background
Smoking rates among people living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS; PLWHA) are at least twice as high as rates in the general population. Consistent with the reciprocal model of pain and smoking, PLWHA with pain who smoke may use smoking as a means of coping with pain, thus presenting a potential barrier to quitting. The aim of this study is to better understand how pain relates to smoking cessation among 474 HIV-positive adults enrolled in a cell phone–delivered smoking cessation trial.
Methods
Participants were randomly assigned to usual care (cessation advice and self-help materials) or 11 sessions of cell phone–delivered smoking cessation treatment. Pain, as assessed by the Medical Outcomes Study-HIV Health Survey (MOS-HIV), and point prevalence abstinence were collected at the 3-month treatment end and at 6- and 12-month follow-ups. Self-reported abstinence was biochemically verified by expired carbon monoxide (CO) level of <7 ppm.
Results
Using multilevel modeling for binary outcome data, the authors examined the relationship between pain and abstinence, from treatment end through the 12-month follow-up. Consistent with the authors’ hypothesis, less pain was associated with greater likelihood of 24-hour (β = .01, t(651) = 2.53, P = .01) and 7-day (β = .01, t(651) = 2.35, P = .02) point prevalence abstinence, controlling for age, gender, baseline pain, nicotine dependence, and treatment group. No pain × treatment group interaction was observed.
Conclusions
These results can help us to better identify PLWHA at greater risk for relapse in smoking cessation treatment. Future research may examine the effectiveness of more comprehensive smoking cessation treatment that incorporates aspects of pain management for PLWHA who smoke and have high pain and symptom burden.
