Article Abstract
Background: Obesity and depressive disorders are significant public health concerns, and their association is well-documented. This study investigates the role of inflammatory markers, specifically C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR), in mediating the relationship between obesity and depressive symptoms.
Methods: We utilized data from 37,538 adults from the National Health and Nutrition Examination Survey (NHANES), covering the period from 2005 to March, 2020, pre-pandemic. Depressive symptoms were measured using the Patient Health Questionnaire-9 (PHQ-9), while inflammatory markers were assessed via NLR and CRP levels.
Results: Results indicated a positive correlation between obesity, NLR, and CRP levels, and depressive symptoms. Notably, CRP exhibited a significant mediating effect in the obesity and depressive symptoms link, whereas NLR did not. (NLR: 0.0926%, = 0.740; CRP: 32%, < 0.001). Furthermore, the mediating effect of CRP in the male group was significantly higher than in the female group (Men: 57%, < 0.001; Women: 16%, = 0.046).
Conclusion: These findings provide new insights into the mechanisms linking obesity and depressive symptoms, especially in men, and may guide future therapeutic strategies.

Cardiac rehabilitation programs (CRPs) are multifactorial interventions defined by the World Health Organization as essential strategies to improve patients' health-related quality of life (HRQoL) by enhancing their physical, psychological, social, and occupational well-being. These programs are a cornerstone in the comprehensive treatment of heart disease, facilitating the recovery of functional capacity and reintegration into the workforce through a multidisciplinary approach. The objective of this study was to assess the efficacy of CRPs in enhancing functional capacity (cardiac and psychological) and HRQoL in workers with ischemic heart disease.
