Investigation on marital status of patients with neuromyelitis optica spectrum disorders in China.

Background: Neuromyelitis optica spectrum disorders (NMOSD) may have a great impact on patients' marriage, and marital status may also affect patients' compliance and prognosis. We investigated the marital status of 494 NMOSD patients in China to explore the mutual influence between them.
Methods: A cross-sectional survey was conducted by the online questionnaires or telephone follow-up. Basic information of all respondents was analyzed from NMOSD-database of West China hospital. All 444 married respondents finished self-assessment of NMOSD's effect on marriage and over 80% of them accepted Marital Cumulative Damage Score (MCDS).
Results: The proportion of unmarried male patients is higher than female (23.1% vs. 9.0%), especially in youth stage (44.0% vs. 20.2%). However, the females reported bigger impacts on their marriage among married NMOSD patients (97.5% vs. 70.7%). Compared to married patients, divorced patients costed more in hospital every time (29,857.1 CNY vs. 15,577.2 CNY), received longer education (12.75 years vs. 9.36 years), had longer duration of disease (117.16 vs. 93.62 months), more relapses (5.50 vs. 3.73) and higher EDSS score (3.58 vs. 2.59). EDSS scores are associated with MCDS (R ² =0.267, P<0.0001), and divorced patients have higher MCDS (P<0.01). Decreased group activities (84.1%), declined working ability (73.7%) and alienation from friends (72.54%) are the first three factors in MCDS.
Conclusion: NMOSD exerts cumulative damage for patients' marriage, and the progression of NMOSD is more likely to lead to marital breakdown. Healthy marriage may improve the prognosis of patients by providing the psychological support and improving treatment compliance.
