Relationship between depression and apolipoproteins A and B: a case–control study
Abstract
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…
