A STUDY OF THE ASSOCIATION BETWEEN RELIGIOSITY AND DEPRESSION IN PATIENTS WITH PARKINSON'S DISEASE

Resumo

INTRODUCTION: Neuropsychiatric comorbidities are common in Parkinson's Disease (PD) and impact patients' quality of life. In parallel, religiosity is associated with the improvement of depressive and anxious symptoms in the general population. However, in other countries, the rates of religiosity among people with PD reported significantly lower levels of religiousness than did age-matched controls. That possibly happens because, in addition to the motor impairment that limits the experience of religious activities, depression, the main neuropsychiatric comorbidity, may influence the religious practices and beliefs of these patients. OBJECTIVES: To assess the level of religiosity in patients with PD and verify an association with depression and quality of life indices. METHODS: Patients with PD diagnosed according to the 2015 MDS criteria were included in this study. We excluded cases with the hypothesis of atypical parkinsonism. Religiosity was assessed using the Duke University Religiosity Index, with 3 components: organizational religiosity (OR), non-organizational religiosity (NOR) and intrinsic religiosity (IR). Beck Depression Index (BDI) and PDQ 39 evaluated depression and quality of life indices, respectively. The cutoff point for moderate depressive symptoms was BDI > 19. The Spearman test was used to assess the correlation between the variables. This study obtained approval from the local ethics committee approval. RESULTS: Twenty-eight patients were included, among which 3 had moderate depressive symptoms. The correlation coefficient between OR/NOR with the other variables was 0.308 for BDI (p=0.111); 0.218 for PDQ 39 (p=0.264) and 0.243 for UPDRS III (p=0.212). As for the relationship between RI and the other scales, the value found was -0.348 for BDI (p=0.069); -0.443 for PDQ 39 (p=0.018) and -0.407 for UPDRS III (p=0.032). Furthermore, the relationships between PDQ 39 and IDB (0.513; p=0.005) and PDQ 39 and UPDRS III (0.614; p<0.001) were analyzed. CONCLUSION: Only IR showed a significant correlation with PDQ 39 and UPDRS III. Intrinsic religiosity was weakly associated with better levels of quality of life and less motor impairment. Although not significant, a trend towards fewer depressive symptoms was observed in patients with a higher degree of intrinsic religiosity. There was also a significant association between quality of life with a lower degree of depressive symptoms and a lower degree of motor impairment.
