Purpose:
Multiple sclerosis (MS) is a debilitating disease accompanied by physical and mental comorbidities. Little is known about the relation between different comorbidities and health-related quality of life (HRQOL) in people with MS (pwMS). Therefore, we designed this study to assess the association between comorbidities and HRQOL.
Methods:
In this cross-sectional study, of 976 pwMS attending the MS clinic of Kashani Hospital in Isfahan, Iran were assessed. The data on comorbidity were extracted from patients' medical records. The 36-Item Short Form Survey (SF-36) was used to measure HRQOL. Firstly, the association between each comorbidity and HRQOL was assessed. Then, the comorbidities were categorized into physical, psychiatric, and autoimmune, and the association of each comorbidity group with HRQOL was evaluated.
Results:
The mean (SD) age and disease duration were 37.58 (9.22) and 7.41 (5.24); most of them were female (82.8%) and had a relapsing course (77.1%). The most common comorbidity was migraine (13.6%), followed by hypothyroidism (13.5%), obsessive-compulsive disorder (OCD) (13.5%), and anemia (11.5%). There was a significant association between the physical component score (PCS) of HRQOL and reduced epilepsy, coronary artery disease, eye diseases, OCD, major depressive disorder (MDD), and borderline personality disorder. Regarding mental component (MCS), ovarian failure, polycystic ovary syndrome, OCD, and MDD had an association with low MCS. After categorization, both physical and psychiatric comorbidities were related to less PCS and MCS score. However, no significant association between autoimmune comorbidities and HRQOL was found.
Conclusion:
Our results show a significant association between comorbidities and HRQOL in MS patients.
Insights
Comorbidities significantly impact health-related quality of life (HRQOL) in multiple sclerosis (MS) patients. Physical and psychiatric conditions, unlike autoimmune ones, were linked to reduced HRQOL scores.
Area of Science:
- Neurology
- Public Health
- Psychiatry
Background:
- Multiple sclerosis (MS) is a chronic neurological disease impacting physical and mental health.
- Comorbidities are common in people with MS (pwMS) but their effect on health-related quality of life (HRQOL) is not fully understood.
Purpose of the Study:
- To investigate the association between various comorbidities and HRQOL in pwMS.
- To determine if physical, psychiatric, or autoimmune comorbidities differentially affect HRQOL.
Main Methods:
- Cross-sectional study of 976 pwMS in Isfahan, Iran.
- HRQOL assessed using the 36-Item Short Form Survey (SF-36).
- Comorbidities extracted from medical records and categorized.
Main Results:
- Migraine, hypothyroidism, obsessive-compulsive disorder (OCD), and anemia were most common comorbidities.
- Physical comorbidities (epilepsy, coronary artery disease, eye diseases) and psychiatric conditions (OCD, major depressive disorder) were associated with lower physical component scores (PCS).
- Psychiatric comorbidities (OCD, major depressive disorder) were linked to lower mental component scores (MCS). Both physical and psychiatric comorbidity groups negatively impacted PCS and MCS.
Conclusions:
- Comorbidities, particularly physical and psychiatric, are significantly associated with reduced HRQOL in pwMS.
- Autoimmune comorbidities did not show a significant association with HRQOL in this cohort.
