ObjectiveTo investigate the risk factors associated with aggression in patients with
schizophrenia.MethodsPatient clinical, behavioural, and demographic information was collected and
reported online to the Beijing Mental Health Information Management System
by psychiatrists. We used chi-square tests to analyse information between
2011 and 2015 to determine the prevalence and incidence of schizophrenia and
the rate of aggression. We used univariate and binary logistic regression to
analyse risk factors of aggressive behaviours.ResultsThe prevalence and incidence of schizophrenia, and the proportion of cases
displaying aggressive behaviour, increased considerably from 2011 to 2015.
Risk of aggression was associated with non-adherence to medication (odds
ratio [OR]: 2.92; 95% confidence intervals [CI]: 2.08–4.11), being unmarried
(OR: 1.62; 95% CI: 1.03–2.55), having physical disease (OR: 3.26; 95% CI:
2.28–4.66), and higher positive symptom scores (OR: 2.01; 95% CI:
1.06–3.81). Physical disease was a risk factor associated with committing
more than one type of aggression.ConclusionWe confirmed that demographic factors, treatment-related factors, and
clinical symptoms were associated with aggression in patients with
schizophrenia in Beijing. A focus on improving controllable factors,
including medication adherence and physical health status, might help to
prevent aggressive behaviour.
