A meta-analysis of worldwide studies, found by a 10-year literature follow-up and/or by searching PubMed, was performed. Forty-two studies across 20 nations consistently demonstrated an association between schizophrenia and current smoking (weighted average odds ratio, OR=5.9; 95% confidence interval, CI 4.9--5.7). In 32 male studies across 18 nations, the weighted average OR was 7.2 (CI, 6.1--8.3). In 25 female studies across 15 nations, the weighted average OR was 3.3 (CI, 3.0--3.6). The… Expand
Epidemiology of Comorbid Tobacco Use and Schizophrenia: Thinking About Risks and Protective Factors
ABSTRACT A meta-analytic review demonstrated that, when compared with the general population, schizophrenia is consistently and strongly associated with current tobacco smoking with a world averageExpand
Worldwide prevalence of smoking cessation in schizophrenia patients: A meta-analysis of comparative and observational studies.
TLDR
It is found that the prevalence of smoking cessation was significantly lower among schizophrenia patients compared to healthy control and those with other psychiatric disorders and better understanding of the barriers to smoking cessation and more effective measures for quitting smoking should be developed for patients with schizophrenia. Expand
Smoking in male patients with schizophrenia in China: A meta-analysis.
TLDR
The pooled prevalence of current smoking of male patients with schizophrenia in China is lower compared to Western and other Asian countries, and possible relationships between lower prevalence ofCurrent smoking and psychopathology in patients with schizophrenic patients require further investigation. Expand
Secondhand smoke exposure and mental health in adults: a meta-analysis of cross-sectional studies
TLDR
Exposure to SHS among non-smoker is associated with depressive symptoms and psychological distress, emphasizing the significance of reducing SHS exposure at a population level. Expand
Smoking and schizophrenia in population cohorts of Swedish women and men: a prospective co-relative control study.
TLDR
This association does not arise from smoking onset during a schizophrenic prodrome and demonstrates a clear dose-response relationship, and smoking prospectively predicts risk for schizophrenia. Expand
Associations of cigarette smoking with psychiatric disorders: evidence from a two-sample Mendelian randomization study
TLDR
It is found that cigarette smoking was causally associated with increased risks of a number of psychiatric disorders, including anxiety, bipolar disorder, insomnia, major depressive disorder, posttraumatic stress disorder, suicide attempts, and schizophrenia. Expand
Smoking is associated with schizophrenia, but not with mood disorders, within a population with low smoking rates: A matched case–control study in Bucaramanga, Colombia
TLDR
It is suggested that the association between schizophrenia and smoking behaviors can stand in populations with low monetary income and low smoking rates, and may not be observable in countries where people have limited economic resources. Expand
Smoking rates among schizophrenia patients in Japan
TLDR
The association between smoking rate and schizophrenia is consistent across countries, including Japan, and this percentage was significantly higher in the schizophrenia than in the control group, adjusting for sex and age. Expand
Incidence of cancer in patients with schizophrenia and their first-degree relatives: a population-based study in Sweden.
TLDR
The significantly decreased incidences of cancers in patients diagnosed with schizophrenia and their unaffected relatives suggest that familiar/genetic factors contributing to schizophrenia may protect against the development of cancer, especially for those cancer sites observed in both settings. Expand
Genetics of schizophrenia and smoking: an approach to studying their comorbidity based on epidemiological findings
TLDR
The approach, which examines the results of epidemiological studies on comorbidities and then looks for genes that simultaneously satisfy epidemiologically suggested sets of hypotheses, may also apply to the study of other major illnesses. Expand

Investigating the association between cigarette smoking and schizophrenia in a cohort study.
TLDR
Cigarette smoking may be an independent protective factor for developing schizophrenia, consistent with animal models showing both neuroprotective effects of nicotine and differential release of prefrontal dopamine in response to nicotine. Expand
Smoking and major depression. A causal analysis.
TLDR
The results suggest that the association between smoking andMD in women is not a causal one but arises largely from familial factors, which are probably genetic, that predispose to both smoking and MD. Expand
Tobacco smoking and bipolar disorder.
TLDR
It is suggested that smoking may be more prevalent in bipolar patients than in the normal population and vulnerability to bipolar illness may make subjects vulnerable to become tobacco smokers. Expand
Factors affecting smoking in schizophrenia.
TLDR
It appears that smoking in schizophrenia is influenced by gender and subtype, and the nature of this association remains uncertain because in the vast majority of the patients smoking initiation occurs earlier than the disease onset. Expand

OBJECTIVE: The prevalence of cigarette smoking among schizophrenia patients is significantly higher than in the general population; this may reflect self-medication of symptoms and/or adverse effectsExpand
The association between high nicotine dependence and severe mental illness may be consistent across countries.
TLDR
New studies, specially designed to test for transcultural differences in nicotine dependence, are needed to verify that nicotine dependence in severely mentally ill patients is consistently high and similar in different countries. Expand

TLDR
Two studies suggest that schizophrenia is strongly associated with smoking, and neither substance use, antipsychotics, nor institutionalism can explain this relationship. Expand

TLDR
In this population-based study, a reduced risk of cancer among persons diagnosed with schizophrenia is demonstrated. Expand

TLDR
Overall multiple ANCOVA demonstrated a significant main effect for smoking status but not gender or the interaction between gender and smoking status, and Smoking status is a significant factor that should be considered in assessment of neuroleptic dose requirements and Neuroleptic side effects.

TLDR
The prevalence of smoking among schizophrenic patients was similar to the rates found in Western cultures, however, the prevalence of substance abuse was lower in Turkish patients as compared with patients in the Western population. Expand
