National study comparing psychiatric presentations among migrants and citizens in Qatar.

Arab countries host 10 % of the global migrant population, yet research on the mental health of migrant workers within this region is notably lacking. Addressing this gap, our study marks the inaugural nationwide investigation into psychiatric conditions among migrant workers compared to native Qatari citizens in an inpatient setting. Employing a retrospective cohort methodology, we scrutinized psychiatric presentations among two cohorts: migrant workers (cohort 1) and Qatari nationals (cohort 2) admitted to psychiatric inpatient facilities in Qatar. Our sample comprised 150 migrant workers and 138 Qatari inpatients, with a predominance of males in both cohorts and mean ages around 34-35 years. The median length of hospitalization was 13 days for migrant workers and 14 days for Qatari patients. Qatari inpatients exhibited a higher prevalence of prior psychiatric history and comorbid physical conditions. The primary diagnosis upon discharge for approximately one-third of patients in both groups was schizophrenia spectrum and other psychotic disorders, with bipolar disorder representing roughly one-quarter of cases in each cohort. Notably, migrant workers demonstrated a higher incidence of depressive disorders, trauma, and stress-related conditions, while Qatari patients were more frequently diagnosed with substance use disorder and displayed aggressive behaviors.
