“…In agreement with the findings of earlier studies [16], [17], smoking was significantly associated with alcohol use in our schizophrenia sample. Several studies have shown a higher prevalence of smoking in schizophrenia patients with lower educational attainment [2], [19]; however, we did not find such association in our sample, which is consistent with three previous studies [12], [16], [17]. This discrepancy might be attributable to the differences in sample characteristic.…”

“…Consequently, high rate of smoking may contribute to reduction in life expectancy and excess morbidity and mortality among people with schizophrenia [5]–[8]. In addition, cigarette smoking also has been demonstrated to be associated with more frequent hospital readmissions, increased financial burden, and higher rate of attempted suicide [9]–[12].…”

“…Some found that smoking was significantly correlated with younger age, earlier age at onset (AAO) of illness, increased number of hospitalizations, elevated risk of suicide, higher doses of antipsychotic agents, more antipsychotic drug induced side-effects, and more severe psychotic symptoms [2], [9], [12], [18], [27]–[30]. Thus schizophrenia smokers may be more serious cases, supporting the viewpoint of smoking as a marker of more severe illness process.…”

ObjectiveTo investigate the prevalence rate of cigarette smoking and its socio-demographic and clinical correlates in Chinese schizophrenia inpatients receiving antipsychotic mono-therapy.MethodsThis study was a cross-sectional, two-site, hospital-based survey. Four hundred and twenty-nine schizophrenia patients (male/female: 66.9% vs. 33.1%) were consecutively recruited from psychosis inpatient wards of two large specialty psychiatric hospitals in mainland China. Patients were assessed using a cigarette smoking questionnaire, the Positive and Negative Symptom Scale, the Simpson Angus Scale, the Barnes Akathisia Rating Scale, and the Abnormal Involuntary Movement Scale. Socio-demographic and other clinical data were also collected. We calculated the prevalence of current smoking in our sample as well as its indirectly standardized prevalence ratio (ISPR) using data from the 2010 Global Adult Tobacco Survey in China.ResultsThe prevalence rate of current smoking was 40.6% in our sample, and 57.5% in males and 6.3% in females. The ISPRs of all patients, men and women were 1.11(95%CI: 0.95∼1.29), 1.07(95%CI = 0.91∼1.24) and 4.64(95%CI = 2.12∼8.82), respectively. The overall and male-specific prevalence of current smoking did not differ significantly between patients and the general population. In multiple logistic regression analysis, male sex, older age, poor marital status, alcohol use, use of first-generation antipsychotics, longer duration of illness, more frequent hospitalizations, and more severe negative symptoms were independently associated with current smoking.ConclusionMale Chinese inpatients with schizophrenia who received a mono-therapy of antipsychotics were not more likely to smoke than the general population. Cigarette smoking is more common in schizophrenia patients with more severe illness.

People with schizophrenia show higher-than-normal rates of type 2 diabetes mellitus (T2DM); however, research on their understanding of diabetes self-efficacy and self-care behaviours is lacking. This study compared differences in scores of self-efficacy and self-care behaviours between outpatients with comorbid schizophrenia and T2DM and outpatients with T2DM alone. Data were collected using the Diabetes Management Self-Efficacy Scale and Summary of Diabetes Self-Care Activity questionnaire. In total, 105 outpatients with schizophrenia and T2DM and 106 outpatients with T2DM returned completed questionnaires. Results of this study revealed that outpatients with schizophrenia and T2DM had significantly lower total self-efficacy and self-care scores than outpatients with only T2DM. The stepwise regression analysis revealed that self-efficacy, the haemoglobin A1C level and current smoking were significant predictors of self-care behaviours in outpatients with comorbid schizophrenia and T2DM, which explained 33.20% of the variance. These findings help mental health professionals improve patient care through a better understanding of self-care behaviours among outpatients with comorbid schizophrenia and T2DM.

“…A correlation between suicide and impulsivity has also been mentioned in some studies (6,10). On the other hand, it can be noted that few studies exist in the literature evaluating the relationship between cigarette smoking in schizophrenia and symptoms and signs, insight, impulsivity, suicide, depression and hopelessness comprehensively (14).

Cigarette smoking in patients with schizophrenia in Turkey: relationships to psychopathology, socio-demographic and clinical characteristics Objective: In individuals with schizophrenia, the prevalence of cigarette smoking is significantly higher than that of the general population. This appears to be associated with specific psychosocial and clinical characteristics. However, there is limited data regarding the relationship between smoking and psychopathology, insight, impulsivity, suicidality, hopelessness and depression In patients with schizophrenia. In this regard, the purpose of this study was to examine the relationship between these characteristics and smoking in patients with schizophrenia in Turkey. Method: In this cross-sectional study, 133 outpatients with DSM-IV diagnosis of schizophrenia were recruited and independently interviewed for nicotine dependency with tobacco use. Scale for Assessment of Negative and Positive Symptoms (SANS and SAPS), Calgary Depression Scale for Schizophrenia (CDSS), Beck Hopelessness Scale (BHS), Barrât Impulsivity Scale (BIS), The Yale-Brown Obsessive-Compulsive Scale (YBOCS), Beck Cognitive Insight Scale, Scale of Unawareness of Mental Disorder (SUMD) were used to. evaluate related psychopathologic variables. Results:The results revealed that smokers with schizophrenia had higher rates of hospitalization, lifetime suicide attempts, more severe psychopathology, higher impulsivity and hopelessness scores than nonsmokers with schizophrenia. In addition, another important result was that smokers with schizophrenia have higher unemployment rates. Conclusion: From this study, we may gain new insights into the role of cigarette smoking in patients of schizophrenia in Turkey. Our findings suggest that cigarette smoking is associated with not only severe psychopathology but also with impulsivity and hopelessness which are related to suicidality, in patients with schizophrenia. This relationship between suicidality, impulsivity and hopelessness may be of clinical importance for patients with schizophrenia.
