Prevalence and impact of comorbid chronic pain and cigarette smoking among people living with HIV

Heavy Versus Light Smoking: Its Association With Opioid Use, Chronic Pain, and Mental Health

INTRODUCTION

There is much concern that substance use treatment programs are rarely integrated with smoking cessation programs. Here, the first national statistics are presented on the connection between heavy vs. light smoking and the opioid epidemic.

METHODS

Using the 2013-2021 Medical Expenditure Panel Survey linked to the National Health Interview Survey, N=81,400 adults-years, logit regressions estimate the impact of heavy vs. light smoking on opioid use, chronic pain, work limitations due to pain, and poor mental health. Analyses were conducted from October 2023 to May 2024.

RESULTS

Only 37 percent of the population has ever smoked, but they used 69% of the nation's annual prescription opioids. Adults who smoked more than 5 cigarettes a day composed 12% of the population but used about the same number of opioids as the 63% of the population who never smoked. Adults who formerly smoked used 16% fewer opioids than adults who currently smoke (p<0.01). The percent with chronic pain during the year varied from 12.2% for adults who never smoked to 14.2% for light smoking, to 16.5% for those smoking more than a pack a day (p<0.01). Severe work limitations due to pain varied from 7.3% for adults who never smoked to 16.9% for those smoking more than a pack a day (p<0.01). Adults smoking more than a pack a day were twice as likely to report fair or poor mental health compared to those who never smoked (29.2% vs 13.6%) (p<0.01).

CONCLUSIONS

As nations deal with the opioid epidemic, integrating smoking cessation programs into substance abuse treatment programs appears prudent.

African American/Black and Latino Adults with Detectable HIV Viral Load Evidence Substantial Risk for Polysubstance Substance Use and Co-occurring Problems: A Latent Class Analysis

Substance use problems are highly prevalent among persons living with (PLWH) in the United States and serve as serious barriers to engagement in HIV care. Yet, in contrast to studies of single substances, little is known about patterns of polysubstance use in this population. Moreover, other risk factors (e.g., financial hardship, incarceration, homelessness, and mental health distress) are also prevalent and complicate HIV management. The present study drew on a cross-sectional survey with African American/Black and Latino (AABL) adult PLWH from low socioeconomic status backgrounds in New York City who were insufficiently engaged in HIV care and evidenced detectable HIV viral load (N = 512). We used latent class analysis (LCA) to explore patterns of polysubstance use and their relationships to financial hardship, incarceration, homelessness, and mental health. LCA yielded three substance use classes: Class 1, a high polysubstance use/high-risk substance use class (9%); Class 2, a polysubstance use/moderate substance use risk class (18%); and Class 3, a moderate polysubstance use/moderate-to-low-risk substance use class (74%). Mental health symptoms were prevalent in all classes, but Class 1 had greater mental health distress than the other two classes. Current homelessness was more prevalent in Classes 1 and 2. We cannot end the HIV epidemic without engaging and treating AABL PLWH who have serious barriers to engagement along the HIV care continuum, and who evidence polysubstance use along with co-occurring risk factors. Clinical settings can develop outreach and engagement approaches to bring this subpopulation of PLWH into care settings, and further, specialized services are needed to successfully screen, treat, and retain them.
