Health-related quality of life of relapsing or remitting multiple sclerosis patients: a case-control study.

Background: Patients with multiple sclerosis (MS) report lower health-related quality of life (HRQoL) than other chronic disease populations. This study aims to identify risk factors of relapsing or remitting multiple sclerosis (RRMS) and assess its impact on HRQoL in Lebanese MS patients. Patients and methods: A three-month case-control study was performed among 75 RRMS case patients recruited from two clinics in Beirut and 225 controls from the general population. Results: Heavy cigarette smoking, moderate and heavy water pipe smoking, vitamin D deficiency, cardiovascular disease, and psychological disorders were significantly associated with RRMS. Linear regression showed that the multiple sclerosis international quality of life global index significantly decreased with the number of relapses, the incomplete recovery between relapses, and the psychological disorder. Higher-income and physical activity had a positive effect on quality of life (QoL). Conclusions: Findings of this study highlighted the risk factors of RRMS, which can be used for informed decision-making and targeted awareness campaigns. Other factors affecting the HRQoL of MS patients should be considered to improve their experience throughout and after treatment. [ABSTRACT FROM AUTHOR]
