“…For example, in most of the psychiatric wards in China, male patients are allowed to smoke, which may also lead to increasing smoking behavior in chronic patients who usually received more inpatient treatments than first-episode and younger patients. As chronic patients are older than first-episode counterparts, it is not surprising that older age was a risk factor of smoking in previous studies (Hou et al, 2011;Zhang et al, 2010c), which was confirmed by this meta-analysis.…”

“…Third, our sample was relatively small and was limited to chronically hospitalized male patients with more severe psychopathology and longer duration of illness than typical psychotic outpatients or first-episode and drug-naïve patients with schizophrenia. Moreover, gender differences in smoking behaviors and BDNF levels in schizophrenia have been reported Zhang et al 2010). Therefore, it is interesting to evaluate whether our findings in the present study could generalize to female subjects.…”

“…Because smoking is substantially more common among Chinese men than in women in schizophrenia (Zhang et al 2010), as well as gender differences in smoking behaviors (De Leon and Diaz 2005), we included only male subjects. The purposes of this study were to determine (1) differences in BDNF levels between smokers and nonsmokers with schizophrenia and (2) any associations between BDNF levels and schizophrenic symptoms in smokers and nonsmokers.…”

“…As smoking is very infrequent among women in China (61% men and 4% women), and because of the gender differences in smoking behaviors, we included only male participants [19]. We therefore compared the lipid profiles in male smokers and non-smokers with schizophrenia and determined whether there is any relationship between the profiles and psychopathological symptoms in these patients.…”

Schizophrenia is associated with a high prevalence of cigarette-smoking and abnormal lipid profiles. The purpose of this study was to determine whether the profiles differ between schizophrenic smokers and non-smokers and whether the lipid profiles are related to psychopathological symptoms. Serum lipid profiles were measured in 130 male inpatients with DSM-IV-defined schizophrenia: 104 smokers and 26 non-smokers. Symptoms were assessed using the Positive and Negative Syndrome Scale (PANSS). Our results showed that positive PANSS symptoms were fewer in smokers than in non-smokers, while the negative symptoms were fewer in those who smoked more cigarettes. Total protein and globulin levels were significantly lower in the smokers than in the non-smokers. However, there was no significant difference in total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol, apolipoprotein A1, or apolipoprotein B between the smokers and non-smokers. However, the PANSS positive subscale had a significant negative correlation with the HDL-c levels (a protective factor) in the smokers but not in the non-smokers. Our findings suggest that schizophrenic patients who smoke have fewer psychotic symptoms, but contrary to expectation, smoking does not alter lipid profile levels.
