Abstract
Background:
Little is known about how multiple sclerosis (MS) presents in Hispanic/Latinx (HL) people with MS (pwMS).
Objective:
Compare age at onset (AAO) and onset severity between HL versus non-Hispanic White (NHW) pwMS.
Methods:
A cross-sectional study leveraged the MS PATHS registry spanning seven US tertiary care institutions. HL was subcategorized as HL White (HLW) and HL Other (HLO; all other races). Multivariable models examined relationships between ethnoracial variables and AAO and self-reported presenting disease course. Models were repeated restricting to those born ⩾1970.
Results:
The study population included 8231 pwMS, including 540 HL (200 HLW, 340 HLO). The sex distribution did not differ across ethnoracial subgroups. From the statistical models (1) HLO pwMS had an earlier AAO and a higher prevalence of initial progressive disease course than NHW pwMS; (2) among all HL pwMS, irrespective of race, AAO did not differ by sex or between relapsing and progressive MS at onset. In younger HLO adults (born ⩾1970), those with progressive MS at onset had an earlier AAO than those with relapsing MS; and (3) in HL pwMS there was no sex-bias in presenting disease course.
Discussion:
Distinct differences in the presentation of MS in HL compared with NHW individuals were observed.
