Title: | The longitudinal association between inflammation and incident depressive symptoms in men: The effects of hs-CRP are independent of abdominal obesity and metabolic disturbances | Contributor(s): | Tully, Phillip J (author) ; Baumeister, Harald (author); Bengel, Jürgen (author); Jenkins, Alicia (author); Januszewski, Andrzej (author); Martin, Sean (author); Wittert, Gary A (author) | Publication Date: | 2015-02 | Early Online Version: | 2014-11-22 | DOI: | 10.1016/j.physbeh.2014.11.058 | Handle Link: | https://hdl.handle.net/1959.11/52479 | Abstract: | Background This cohort study evaluates whether the association between low-grade inflammation and incident depressive symptoms is independent of abdominal obesity and metabolic disturbances. Methods A cohort of 1167 non-depressed men aged 35 to 80 years were followed up over 5 years to assess incident depressive symptoms measured by the Centre for Epidemiology Scale—Depression or Beck Depression Inventory—I. Venous tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and high sensitivity C-reactive protein (hsCRP) were quantified at baseline and 5 years. Logistic regression determined whether hsCRP, IL-6 and TNF-α were associated with incident depressive symptoms independent of abdominal obesity and metabolic factors. Ancillary analysis utilizing depression z scores stratified participants by waist circumference ≥ 102 cm and ≥ 2 metabolic disturbances. Results Incident depressive symptoms occurred in 95 men at 5 years (8.14% of total). Clinically relevant depressive symptoms were associated with baseline hsCRP (adjusted OR = 1.04; 95% CI 1.00–1.07, p = .03) and annualized ΔhsCRP (adjusted OR = 1.04; 95% CI 1.01–1.08, p = .02). Ancillary analysis showed that the association between annualized ΔhsCRP and depression z score was only significant in men with waist circumference < 102 cm (β = .19, p < .001) and ≤ 1 metabolic disturbance (β = .18, p < .001). None of the measured cytokines were significantly associated with depression. Conclusions hsCRP and annualized ΔhsCRP were positively associated with depressive symptoms in a cohort of men. Further investigation into the role of abdominal obesity and metabolic disturbances in the inflammation–depression hypothesis is warranted. | Publication Type: | Journal Article | Grant Details: | NHMRC/627227 | Source of Publication: | Physiology & Behavior, v.139, p. 328-335 | Publisher: | Elsevier Inc | Place of Publication: | United States of America | ISSN: | 1873-507X 0031-9384 |
