Abstract: BackgroundThere is limited research regarding the prevalence of betel quid use and its effects on symptoms of patients with schizophrenia. Available studies suggest an association between betel chewing and positive symptoms among males with schizophrenia. AimsThis study aimed to compare the prevalence of betel quid chewing between patients with and without mental illness, and to explore the association between betel quid use, symptoms of schizophrenia and side effects of psychotropic medication. MethodsA cross sectional descriptive study was carried atoutpatient clinics at a tertiary care hospital in Sri Lanka. A structured interview schedule was administered to all participants. ResultsOut of 1000 participants, 20.9% chewed betel quid (95%CI: 18.4% - 23.4%). The rate of betel chewing among patients with and without a mental illness was 20.7% (95% CI: 17.0% - 24.4%) and 21.0% (95% CI: 17.6% - 24.5%) respectively and there was no significant difference between the two groups. There was no statistically significant difference between the occurrence of positive or negative symptoms and extra pyramidal side effects in patients with schizophrenia who did and did not chew betel. Female gender (p=0.004) and betel quid chewing (0.002) were associated with more anticholinergic side effects. ConclusionsThere was no association between betel quid usage and the occurrence of positive or negative symptoms of schizophrenia or extra pyramidal side effects.
