Objective: To determine the factors associated with the development of depression, anxiety and stress in the context of the COVID-19 pandemic in police officers in Lima, Peru. Methods: Analytical cross-sectional study conducted in 210 police officers who were administered the Depression Anxiety and Stress Scale-21 (DASS-21) in October 2020, as well as a form, via Google Forms, to obtain sociodemographic and clinical data. A bivariate and a multivariate analysis were performed using crude and adjusted prevalence ratios, with a confidence interval >95% and a significance level of p≤0.05. Results: Depression, anxiety and stress prevalence rates were 11.43%, 10% and 7.62%, respectively. In the bivariate analysis, anxiety was associated with the number of children (cPR:3.18; 95% CI [1.10-9.17]; p:0.032) and history of disease (cPR:2.50; 95%CI[1.08-5.75]; p:0.031)...
