Gender Differences In Smoking Behaviour And Cessation, Chizimuzo T.C. Okoli, Iris Torchalla, Natalie Hemsing, Lorraine Greaves

Chizimuzo T.C. Okoli

This article reviews the literature to compare differential outcomes among men and women after smoking cessation, assess barriers they may face during cessation and provide recommendation to address gender-specific challenges in smoking cessation interventions. There is some evidence that women achieve lower abstinence rates than men after a quit attempt with nicotine replacement therapy, as well as without pharmacotherapy, and several underlying mechanisms were discussed to account for these findings. These include: (a) women have specific genetic variants that affect pharmacokinetics and pharmacodynamics of the medication, (b) hormonal influences increase nicotine metabolism and withdrawal symptoms, (c) women are more responsive …

Smoking Cessation Among Persons With Co-Occurring Substance Use Disorder And Mental Illness, Chizimuzo T.C. Okoli, Milan Khara

Chizimuzo T.C. Okoli

Aims: A history of either a substance use disorder (SUD) or psychiatric disorder (PD) is associated with tobacco use. However, there is limited information available on tobacco dependence treatment outcomes among individuals with co-occurring SUD and PD. Methods: Data from 202 participants enrolled in a tobacco dependence treatment program in an outpatient clinic setting were analysed. Findings: In multivariate analysis, having a history of SUD only (OR =.11, 95% CI = .02–.76) and having a co-occurring SUD and PD (OR = .13, 95% CI = .02–.81), as compared to having neither, were significant predictors of a lower likelihood of achieving …

Men's Smoking Cessation Interventions: A Brief Review, Chizimuzo T.C. Okoli, Iris Torchalla, John L. Oliffe, Joan L. Bottorff

Chizimuzo T.C. Okoli

Background: Smoking is associated with adverse health effects and significant disease burden among men, making it an important men's health issue. Conversely, smoking cessation is associated with significant reductions in smoking-attributable risk. However, few studies have examined men-specific smoking cessation programs. The aim of our study was to conduct a comprehensive review of the literature to identify men-specific smoking cessation programs to make recommendations about future efforts to develop, implement and evaluate men-centered smoking cessation interventions.

Methods: A comprehensive search of the COCHRANE Library, MEDLINE, and PsycINFO and SIGLE databases was performed. Out of 873 studies that we retrieved from …

Trauma, Psychiatric Disorders, Substance Use, And Smoking Among Women, Chizimuzo T.C. Okoli, Nancy Poole, Natalie Hemsing, Karin O'Leary

Chizimuzo T.C. Okoli

Despite decreasing smoking rates among women in the general population, there remain subgroups of women characterized by high nicotine dependence, who remain less able to quit.

One subgroup of women who continue to smoke at rates higher than the general population are those who: have past experiences of trauma, are vulnerable to psychiatric disorders and have substance use problems/addictions.

However, the prevalence of the co-occurrence of trauma, psychiatric disorders, and substance use problems/ addictions, with smoking among women has not previously been synthesized.

The purpose of this study is to conduct a comprehensive review to identify the prevalence of smoking …

Treatment Outcomes From The Tdc: A Look At Smoking Cessation Among Patients With Co-Occurring Substance Use And Psychiatric Disorders, Chizimuzo T.C. Okoli

Chizimuzo T.C. Okoli

Summary of Key Findings

• Smoking abstinence at end of program:
• Intent to treat analysis: 32.2% (83/258)
• Among program completers: 41.3% (83/201)

• Significant predictors of abstinence:
• Having an alcohol, heroin (or other opioid) or marijuana use history was a significant predictor of being less likely to quit smoking when compared to having no history of substance use disorder.
• Having a lower CO level at program enrolment was a significant predictor of being more likely to quit
• Attending the TDC program for a longer duration was a significant predictor of being more likely to quit.
