Triglycerides, cholesterol, and depressive symptoms among undergraduate medical students: a cross-sectional study

Depression is one of the most common mental disorders among undergraduate stu-dents, particularly those in medical training, who face high academic demands and emotional burdens. Biological factors such as lipid abnormalities have been proposed as contributors to depressive symptoms, although evidence in this group is scarce. Therefore, we aimed to evaluate the association between triglyceride and total choles-terol levels and depressive symptoms in medical students.抑郁症是本科生群体中最为常见的精神障碍之一，其中尤以接受医学培养的医学生为代表，该群体面临着高强度的学业要求与情感负担。诸如脂质异常一类的生物学因素已被提出为抑郁症状的潜在诱因，但针对医学生群体的相关研究证据仍较为匮乏。因此，本研究旨在评估医学生体内甘油三酯（triglyceride）与总胆固醇（total cholesterol）水平和抑郁症状之间的关联。
