RESUMO

OBJECTIVE: To investigate the relation between major depressive disorder and metabolic risk factors of coronary heart disease. INTRODUCTION: Little evidence is available indicating a relationship between major depressive disorder and metabolic risk factors of coronary heart disease such as lipoprotein and apolipoprotein. METHODS: This case-control study included 153 patients with major depressive disorder who fulfilled the criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV), and 147 healthy individuals. All participants completed a demographic questionnaire and Hamilton rating scale for depression. Anthropometric characteristics were recorded. Blood samples were taken and total cholesterol, high-and low-density lipoproteins and apolipoproteins A and B were measured. To analyze the data, t-test, χ2 test, Pearson correlation test and linear regression were applied. RESULTS: Depression was a negative predictor of apolipoprotein A (β = -0.328, p<0.01) and positive predictor of apolipoprotein B (β = 0.290, p<0.05). Apolipoprotein A was inversely predicted by total cholesterol (β = -0.269, p<0.05) and positively predicted by high-density lipoprotein (β = 0.401, p<0.01). Also, low-density lipoprotein was a predictor of apolipoprotein B (β = 0.340, p<0.01). The severity of depression was correlated with the increment in serum apolipoprotein B levels and the decrement in serum apolipoprotein A level. CONCLUSION: In view of the relationship between apolipoproteins A and B and depression, it would seem that screening of these metabolic risk factors besides psychological interventions is necessary in depressed patients
