Abstract
Introduction: Major depressive disorder (MDD) is one of the most prevalent mental disorders associated with various negative impacts such as lower overall quality of life, increased morbidity risk, and even premature mortality. According to the biopsychosocial model of health and disease, multiple factors contribute to the development and manifestation of MDD. Here, we assessed social, psychological, and biological variables and tested their power to predict MDD diagnosis using logistic regression models.
Methods: In twenty-four patients with current MDD diagnosis and thirty-five healthy control participants, the following variables were measured to test for associations with MDD diagnosis: (1) emotional neglect and adult attachment style as social variables, (2) thought suppression and cognitive reappraisal as psychological variables, and (3) mitochondrial biogenesis (citrate synthase activity as a surrogate marker of mitochondrial density) measured in peripheral blood mononuclear cells (PBMC) as a biological variable.
Results: The following biopsychosocial variables were associated with MDD diagnosis. Participants with greater emotional neglect (OR: 1.273, 95 % Cl: 1.059-1.645), higher levels of intrusive thoughts (OR: 1.738, 95 % Cl: 1.282-3.066), and decreased mitochondrial density in PBMC (OR: 0.298, 95 % Cl: 0.083-0.784) had a higher probability of belonging to the MDD group.
Conclusions: In line with biopsychosocial models of depression, the present results indicate that variables at different level of analysis are conjointly related to MDD. These findings open new perspectives for the diagnosis and treatment of MDD, but they need to be replicated in larger samples in the future.
期刊介绍:
The rapidly expanding area of research known as neuroimmunomodulation explores the way in which the nervous system interacts with the immune system via neural, hormonal, and paracrine actions. Encompassing both basic and clinical research, ''Neuroimmunomodulation'' reports on all aspects of these interactions. Basic investigations consider all neural and humoral networks from molecular genetics through cell regulation to integrative systems of the body. The journal also aims to clarify the basic mechanisms involved in the pathogenesis of the CNS pathology in AIDS patients and in various neurodegenerative diseases. Although primarily devoted to research articles, timely reviews are published on a regular basis.
