Reduced serum adiponectin levels in alexithymia

Area of Science:

• Psychoneuroimmunology
• Metabolic disease research

Background:

• Alexithymia is associated with altered cytokine profiles.
• Adiponectin and resistin are key adipokines with immunomodulatory roles.

Purpose of the Study:

• To investigate the independent association of adiponectin and resistin with alexithymic features.
• To examine these relationships in a population-based sample.

Main Methods:

• Utilized data from the Kuopio Depression Study general population sample (n=308).
• Compared subjects with high alexithymic features (n=85) to non-alexithymic controls (n=206) based on Toronto Alexithymia Scale scores.
• Assessed serum adiponectin and resistin levels.

Main Results:

• Significantly lower serum adiponectin levels were observed in subjects with alexithymic features.
• No significant difference in resistin levels between groups.
• Logistic regression confirmed lower adiponectin, but not resistin, associated with alexithymia, even after adjusting for multiple confounders.

Conclusions:

• Findings suggest a disturbed anti-inflammatory balance in alexithymia.
• Results expand the understanding of alexithymia, implicating immune system alterations and stress.
