Objective: The aim of the present study was to determine the sociodemographic and clinical correlates of the gender of Chinese schizophrenia outpatients and their impact on patients quality of life (QOL).
Methods: Two hundred and fifty-five clinically stable schizophrenia outpatients were randomly selected in Hong Kong. Counterparts matched according to gender, age, age at onset, and length of illness were recruited in Beijing, China. All of the subjects at both sites were interviewed by the same investigator using standardized assessment instruments.
Results: The combined Beijing-Hong Kong sample contained 251 male and 254 female patients. On univariate analysis more male patients were employed, they had a significantly higher monthly income, and took higher doses of antipsychotic drugs. No difference was found, however, in any of the QOL domains between the genders. On multivariate analysis being employed, taking a higher dose of antipsychotic drugs, having more severe extrapyramidal side-effects, and a higher score on the physical domain of QOL were independently associated with male gender.
Conclusion: Female gender is independently associated with lower scores on the physical aspects of QOL, but there is no difference between the genders in the psychological, social and environmental aspects.
