Peripheral adiponectin levels in anxiety, mood, trauma- and stressor-related disorders: A systematic review and meta-analysis [link]Website  abstract   bibtex   
Background: Anxiety, mood, trauma- and stressor-related disorders confer increased risk for metabolic disease. Adiponectin, a cytokine released by adipose tissue is associated with these disorders and obesity via inflammatory processes. Available data describing associations with mental disorders remain limited and conflicted. Methods: A systematic search was conducted for English, peer-reviewed articles from inception until February 2019 that assessed for serum or plasma adiponectin levels in adults with an anxiety, mood or trauma-related disorder. Diagnoses were determined by psychiatric interview, based on DSM-IV, DSM-5 or ICD-10 criteria. Analyses were performed using STATA 15 and Standardized mean difference (SMD) with 95% confidence interval was applied to pool the effect size of meta-analysis studies. Results: In total 65 eligible studies were included in the systematic review and 30 studies in this meta-analysis. 19,178 participants (11,262 females and 7916 males), comprising healthy adults and adults with anxiety, mood and trauma-related disorders, were included. Overall results indicated an inverse association between adiponectin levels and examined mental disorders. Specifically, patients with an anxiety disorder (SMD = −1.18 µg/mL, 95% CI, −2.34; −0.01, p = 0.047); trauma or stressor-related disorder (SMD = −0.34 µg/mL, 95% CI, −0.52; −0.17, p = 0.0000) or bipolar disorder (SMD = −0.638 µg/mL, 95% CI, −1.16, −0.12, p = 0.017) had significant lower adiponectin levels compared to healthy adults. Limitations: Heterogeneity, potential publication bias, and lack of control for important potential confounders were significant limitations. Conclusion: Peripheral adiponectin levels appear to be inversely associated with anxiety, mood, trauma- and stressor related disorders and may be a promising biomarker for diagnosis and disease monitoring.
