Introduction. Healthcare students are subjected to high-stress levels due to different academic, social, and financial stressors. Persistent and severe stress might predispose students to depression and anxiety. Therefore, this research aims to investigate the level of perceived stress among healthcare students and its relation to anxiety and depression.Methods. A prospective cross-sectional study using a validated questionnaire was conducted among healthcare students in Saudi Arabia. The 14-item Perceived Stress Scale (PSS) was used to evaluate perceived stress, and depression and anxiety were measured using the Hospital Anxiety and Depression Scale (HADS). All statistical analyses were carried out using PSPP Statistical Analysis Software version 1.2.0.Results. A total of 701 respondents participated in this study. The average age of the students was 20.9 years old, and 59.3% were female. Almost three-quarters of students perceive themselves as stressed. Around two-thirds were categorized as having borderline/cases of depression or anxiety. Perceived stress was four times more likely among students with cases of anxiety [Adjusted Odds Ratio (AOR) = 4.83; 95% CI 2.89, 8.06], depression [AOR = 4.79; 95% CI 2.68, 8.53] as compared with those without these conditions.Conclusions. Stress is highly prevalent among healthcare students, and it is strongly associated with female gender and students’ anxiety and depression. Therefore, the mental health of healthcare students is an essential factor affecting perceived stress and at-risk individuals. Therefore, preventative mental health interventions targeting healthcare students are necessary to help improve mental health and cope with stressors in academic education.
