Effects of smoking on cognitive function in male inpatients with schizophrenia
Abstract：Objective To explore the effects of smoking on cognitive function in male inpatients with schizophrenia .Methods Cognitive function was measured using MATRICS Consensus Cognitive Battery (MC‐CB) in 149 male schizophrenic inpatients with smoking and 75 schizophrenic inpatients without smoking with cross -sectional studies .Clinical symptoms were assessed using Positive and Negative Syndrome Scale (PANSS) in all patients .The cognitive function and clinical symptoms were compared between two groups ,the correlation between smoking and cognitive function was explored .Results There was no significant difference in clinical symptoms between smoking patients and non -smoking patients .Scores of digital sequence test [(14 .52 ± 5 .51)vs(17 .39 ± 5 .54)] ,verbal learning test [(17 .11 ± 5 .56)vs (19.69 ± 6 .05)] ,and brief visual memory test [(13 .41 ± 8 .10)vs (16 .96 ± 8 .06)] were significantly decreased in patients with smoking comparing with that of patients without smoking (P< 0 .05) .No sig‐nificant correlations were shown between cognitive function and smoking indexes such as smoking times , smoking amount and smoking index (P> 0 .05) .Conclusions Smoking may exacerbate cognitive deficits in male patients with schizophrenia ,especially on memory .
