Relationship of DSM-IV-Based Depressive Disorders to Smoking Cessation and Smoking Reduction in Pregnant Smokers

THE AMERICAN JOURNAL ON ADDICTIONS, Issue 4 2006
Janice A. Blalock PhD
This study investigated DSM-IV depressive disorders as predictors of smoking cessation and reduction in 81 pregnant smokers participating in a smoking cessation trial. Thirty-two percent of the sample met criteria for current dysthymia, major depressive disorder in partial remission, or minor depression. There was no significant reduction in smoking among women with or without current depressive disorders. Unexpectedly, as compared to women without depressive disorders, women with dysthymia significantly increased the mean number of cigarettes smoked (from 8 to 23 cigarettes per day during the 2 to 30 days post-targeted quit date period) and were smoking significantly more cigarettes at 30 days. A main effect approaching significance suggested that women with current depressive disorders were less likely to be abstinent than women without current depressive disorders (OR = 6.3; 3.9% vs. 12.7% at 30 days post-targeted quit date; 0% vs. 6.2% at 30 days post-partum). Results add to previous findings indicating a correlation between depressive symptoms and continued smoking in pregnant women. Further investigation of mood-focused smoking cessation interventions may be warranted. [source]


Smoking cessation in severe mental illness: what works?

ADDICTION, Issue 7 2010

ABSTRACT Aims The physical health of people with severe mental illness (SMI) is poor. Smoking-related illnesses are a major contributor to excess mortality and morbidity. An up-to-date review of the evidence for smoking cessation interventions in SMI is needed to inform clinical guidelines. Methods We searched bibliographic databases for relevant studies and independently extracted data. Included studies were randomized controlled trials (RCTs) of smoking cessation or reduction conducted in adult smokers with SMI. Interventions were compared to usual care or placebo. The primary outcome was smoking cessation and secondary outcomes were smoking reduction, change in weight, change in psychiatric symptoms and adverse events. Results We included eight RCTs of pharmacological and/or psychological interventions. Most cessation interventions showed moderate positive results, some reaching statistical significance. One study compared behavioural support and nicotine replacement therapy (NRT) to usual care and showed a risk ratio (RR) of 2.74 (95% CI 1.10,6.81) for short-term smoking cessation, which was not significant at longer follow-up. We pooled five trials that effectively compared bupropion to placebo giving an RR of 2.77 (95% CI 1.48,5.16), which was comparable to Hughes et al.'s 2009 figures for general population data; RR = 1.69 (95% CI 1.53,1.85). Smoking reduction data were too heterogeneous for meta-analysis, but results were generally positive. Trials suggest few adverse events. All trials recorded psychiatric symptoms and the most significant changes favoured the intervention groups over the control groups. Conclusions Treating tobacco dependence is effective in patients with SMI. Treatments that work in the general population work for those with severe mental illness and appear approximately equally effective. Treating tobacco dependence in patients with stable psychiatric conditions does not worsen mental state. [source]


The feasibility of smoking reduction: an update

ADDICTION, Issue 8 2005
John R. Hughes
ABSTRACT Aim To update conclusions of a previous review of smoking reduction on the extent to which (1) smokers spontaneously reduce their smoking, (2) smokers who try to quit and fail return to smoking less, (3) smokers can substantially reduce and maintain reductions via pharmacological and behavioral treatments and (4) smokers compensate when they reduce. Method Qualitative systematic review. Data sources Systematic computer searches and other methods. Study selection Published and unpublished studies of smokers not trying to stop smoking. We located 13,26 studies for each of the four aims. Data extraction The first author entered data with confirmation by second author. Data synthesis Due to the heterogeneity of methods and necessity of extensive recalculation, a meta-analysis was not feasible. Results Few daily smokers spontaneously reduce. Among those who try to stop smoking and relapse, some return to reduced smoking but whether they maintain this reduction is unclear. Nicotine replacement (and perhaps behavior therapies) can induce smokers not interested in quitting to make significant reductions in their smoking and maintain these over time. Some compensatory smoking occurs with reduction but significant declines in smoke exposure still occur. Conclusions These results indicate that reduction is feasible when aided by treatment. Whether reduction should be promoted will depend on the effect of reduction on health outcomes and future cessation. [source]


Balancing absolute and relative risk reduction in tobacco control policy: the example of antenatal smoking in Victoria, Australia

Abstract Objective: This descriptive epidemiological analysis aims to explore the benefits, risks and policy balance between a whole-of-population and high-risk reduction approach to reducing antenatal smoking prevalence. Methods: Using Victorian hospital antenatal statistics the rate-ratio for smoking in each hypothesised high prevalence group was calculated and combined with the absolute number of births in each high-risk group. The effect on smoking prevalence of whole-of-population reductions and high-risk group reductions was then modelled. Results: In Victoria, there were higher rates of antenatal smoking among single [RR = 4.67 (3.46,4.42)], teenage women [RR (95%CI) = 3.26 (3.00,3.54)] of indigenous ethnicity [RR = 4.39 (3.94, 4.88)] with low income [RR = 4.67 (4.17,5.22)] and low education attainment [RR = 3.89 (3.47,4.36)] who lived in less accessible areas [RR = 2.14 (1.92,2.39)]. However, as each of these high-risk groups represents a relatively small proportion of mothers, most antenatal smokers are aged 25,34, educated, city-based, non-Indigenous and non-impoverished. Conclusions: The majority of Victorian women who smoke in pregnancy do not belong to traditional high-risk groups. Implications: Absolute reductions in smoking prevalence in high-risk groups can potentially be achieved by whole-of-population prevalence reductions, despite a potential continuance in high relative risk among these groups. Conversely, an exclusive focus on smoking reduction in high-risk groups may fail to reduce the whole-of-population antenatal smoking prevalence. [source]
