Logistic regression analyses were used to see the association between different variables and the outcome variable. Odds ratios with 95% Confidence Interval (CI) were computed to determine the presence and strength of the association.ResultsIn this study, the prevalence of workplace violence was 29.9% [95% CI: 26.5, 33.5)] of which physical violence accounted for 36 (18.22%), verbal abuse for 172 (89.58%) and sexual harassment for 25 (13.02%).
