Patients with major depressive disorder may have significantly high Triglyceride levels and CVD risk: Study

Until March 2023, the studies were searched in the Cochrane, EMBASE, PsycINFO, and PubMed databases. The standardized mean difference (SMD) was calculated by extracting the mean (±SD) for TG concentrations and combining them quantitatively using random-effects meta-analysis. Meta-regression and subgroup analysis were used to investigate the heterogeneity resource.

38 studies that measured peripheral blood TG concentrations in 3272 HCs and 2604 MDD patients were included. According to the findings of the meta-analysis, the patients with MDD had significantly higher TG levels than HCs. There was evidence of heterogeneity (χ2 = 269.97, p < 0.01, I2 = 85%). Subgroup analysis revealed that there were no differences across groups, although there were significant variations in TG levels between patients with MDD and HCs based on age, body mass index, and medication usage (p < 0.05). Additionally, meta-regression revealed no significant factors. Overall, these results point to the need to measure the possible advantages of a low-triglyceride diet in MDD patients and look into the possible roles of triglycerides in the pathophysiology of depression.
