Abstract
The relationship between major depression and increased platelet activity has been previously stated by several studies. This study sought to test the relationship between mean platelet volume (MPV) – an indicator of platelet activity – and major depression, in an adult Turkish population sample. Respondents were 2286 participants interviewed in a regional survey. The diagnosis of current (one month) major depression was made according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. MPV was measured along with total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, BMI, and waist circumference. Two hundred eighty-nine participants (12.5%) were diagnosed as having major depression. Patients with major depression were found to have increased MPV levels in comparison with participants without depression (p = 0.001). After excluding the subjects with risk factors capable of influencing platelet activity, MPV was still found to be elevated in patients with major depression compared with non-depressed individuals (p < 0.01). Linear regression analysis revealed a significant independent association of major depression with MPV levels (r = 0.123; p = 0.001). According to the findings of this study, increased MPV (or platelet activation) is associated with current (one month) diagnosis of major depression. Future research should investigate the effect of depression treatment on MPV.
