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 …

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 …

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 …

This report examines interventions designed to reduce or eliminate smoking during pregnancy. It considers these interventions using a “better practices” methodology designed by Moyer, Cameron, Garcia, and Maule (2002, p. 124) for intervention studies published prior to 2003, and a systematic review methodology from the National Institute for Health and Clinical Excellence (NICE) (2006) in the UK for those studies published after 2003. We contextualize the results of these analyses in the wider literature on women’s health, women-centred care, and women’s tobacco use to better interpret them. These results build on those in the first edition of Expecting to Quit …

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 …

Background: In many countries, smoking remains the leading preventable cause of death. In North America, reductions in population smoking levels are stabilising and, in recent years, those involved in tobacco control programming have turned their attention to particular segments of society that are at greatest risk for tobacco use. One such group is people with mental illness. A picture of tobacco use patterns among those with mental illness is beginning to emerge; however, there are several unanswered questions. In particular, most studies have been limited to particular in-patient groups. In addition, while it is recognised that men and women differ …

Current evidence confirms that young women who smoke or who have regular long-term exposure to secondhand smoke (SHS) have an increased risk of developing premenopausal breast cancer. The aim of this research was to examine the responses of young women to health information about the links between active smoking and SHS exposure and breast cancer and obtain their advice about messaging approaches. Data were collected in focus groups with 46 women, divided in three age cohorts: 15–17, 18–19 and 20–24 and organized according to smoking status (smoking, non-smoking and mixed smoking status groups). The discussion questions were preceded by information …

Are There Differences In The Smoking Identities Of Adolescents Boys And Girls?, Chizimuzo T.C. Okoli, Iris Torchalla, Pamela A. Ratner, Joy L. Johnson
Are There Differences In The Smoking Identities Of Adolescents Boys And Girls?, Chizimuzo T.C. Okoli, Iris Torchalla, Pamela A. Ratner, Joy L. Johnson
Chizimuzo T.C. Okoli
Purpose:
To assess sex-disaggregated differences in youth characterizations of their own smoking behaviour
Background:
•Smoking identities represent psychosocial constructions of how adolescents who smoke perceive themselves in relation to their smoking behaviour (e.g, ex-smoker, social smoker, occasional smoker, e.t.c.)
•These smoking identities converge (or diverge) with established taxonomies used to describe youth smoking behaviour
•Few quantitative studies have examined differences in smoking identity between boys and girls
Is Exposure To Peer And Family Smoking Associated With Youths' Initial Smoking Experiences?, Chizimuzo T.C. Okoli, Chris G. Richardson, Joy L. Johnson
Is Exposure To Peer And Family Smoking Associated With Youths' Initial Smoking Experiences?, Chizimuzo T.C. Okoli, Chris G. Richardson, Joy L. Johnson
Chizimuzo T.C. Okoli
Background:
- Peers and family member’s smoking is associated with adolescent smoking.
- Sensitivity to the initial smoking experience, determined by positive (for e.g., feeling relaxed, high, and good) and/or negative (for e.g., feeling nervous, sick, coughing) symptoms upon initial smoking experimentation, is also associated with youth smoking.
- However, the effect of peer and family member’s smoking on the initial smoking experiences of adolescents has not been previously studied.
- We present the findings of a cross-sectional analysis assessing the association between exposure to smoking from peers and family members on the symptoms of the initial smoking experience of …
Assessing Secondhand Tobacco Smoke Exposure Among Persons With Severe And Persistent Mental Illness, Chizimuzo T.C. Okoli, Joy L. Johnson, Leslie Malchy
Assessing Secondhand Tobacco Smoke Exposure Among Persons With Severe And Persistent Mental Illness, Chizimuzo T.C. Okoli, Joy L. Johnson, Leslie Malchy
Chizimuzo T.C. Okoli
Background
• Secondhand tobacco smoke (SHS) exposure increases the risk for cancer, respiratory illness, and cardiovascular disease.
• Individuals with severe and persistent mental illness (SPMI) have a higher smoking prevalence than the general population, placing them at increased risk for related morbidity and mortality.
• Given the higher smoking prevalence in this population, the risk for SHS exposure among smokers and nonsmokers with SPMI should be an issue of concern. Yet, SHS exposure in this population is understudied.
• The purpose of our study was to examine the correlates of SHS exposure in this population. Our specific aims were …

Smoking Cessation And Drug Treatment: Identifying Gaps, Milan Khara, Chizimuzo T.C. Okoli, Ric M. Procyshyn, Joy Johnson, Alasdair Barr, Lorraine Greaves
Chizimuzo T.C. Okoli
BACKGROUND: An estimated 70% - 90% of individuals in drug treatment con-currently smoke cigarettes. Although individuals in drug treatment settings are motivated and can succeed in smoking cessation, there is still a lack of systematic knowledge regarding the long-term abstinence, methods employed for successful cessation, and the barriers to smoking cessation in this population.
OBJECTIVES: To: a) describe types of smoking cessation interventions (i.e., cognitive-behavioral and/or pharmacotherapy) employed in drug treatment settings, b) determine the effectiveness of such interventions, and c) identify gaps in knowledge regarding smoking cessation interventions among the drug treatment populations
METHODS: A comprehensive review of the …

Chizimuzo T.C. Okoli
Background
Despite considerable medical and research attention, smoking in pregnancy remains a serious public health problem, especially among young and disadvantaged women in high income countries and general populations of women in low and middle income countries. Facilitating successful and enduring smoking cessation during pregnancy and preventing relapse is therefore an ongoing public health challenge globally
Objectives
This Canadian project is aimed at better breaking the cycle of smoking during pregnancy, or quitting and relapsing during postpartum; especially for young, disadvantaged women. Equally, it will address the apparent blockages to effective uptake by health professionals, of research evidence and better …

Background
•Despite considerable efforts by health care professionals, and an overall reduction in smoking prevalence, it is estimated that approximately 20% to 30% of pregnant women still smoke during pregnancy
•To date, smoking cessation interventions to reduce smoking during pregnancy and postpartum have been relatively unsuccessful. Despite the influx of research examining smoking and pregnancy over the last five years, the prevalence of smoking among pregnant and postpartum women has only slightly decreased
•Advice to quit smoking by health care providers, is associated with increased smoking cessation attempts in the general population. Also, studies have shown that smoking cessation interventions …
