Results The recovery rate of the questionnaire was 96.5%, and 164 qualified questionnaires were obtained. Fourteen students (8.5%) had depression and 28(17%) had anxiety problems. Fifty-seven cases (34.76%) needed the help of self-rating questionnaire and 110 cases (67.07%) needed the help of depression and anxiety counseling. The proportion of demand for depression/anxiety counseling among sixth grade medical students was significantly higher than that of fifth grade (82% vs 50%; P＜0.05) and seventh grade (82% vs 57%; P＜0.05).
