P0428 - Acculturation and lower socioeconomic status are associated with early disability in Hispanic/Latinx with Multiple Sclerosis. (ID 1494)
Abstract
Background
Acculturation and socioeconomic (SES) factors are known to play a large role in racial and ethnic health disparities in the United States (US). Lower SES has been reported to increase the risk of disability progression in multiple sclerosis (MS) in whites. How these measures relate to early MS in vulnerable US populations is not known. This is being evaluated as part of GAHMS, a prospective longitudinal study of Genetic ancestry and Acculturation in Hispanic background with early MS.
Objectives
To examine the association of sociodemographic and acculturation measures in early MS disability in Hispanic/Latinx (Latinx).
Methods
Cross-sectional assessment of 219 self-identified US Latinx, including Puerto Rico. Early MS was defined as a diagnosis of <5 years. Sociodemographic status (SES) markers (education, household income, public assistance) and acculturation measures including language preference, place of birth, years in the US and Short Acculturation Scale for Hispanics (SASH; a composite measure of acculturation to US) were collected as part of the baseline examination. Bivariate correlations assessed SASH correlation with acculturation proxies. Unadjusted and adjusted multivariable logistic and linear regression were used to examine the relationship between ambulatory disability (using the Expanded Disability Status Scale; EDSS) and acculturation and SES.
Results
Most participants were female (75.8%), had a mean age of onset of 30.65 years (SD±13.93), had relapsing remitting MS (85.3%), and self-identified as Latinx with Caribbean (46.3%) or Mexican origin (37.8%). Most were overweight (BMI Mean: 28.9±8.04) and unemployment was reported by 35%. A strong correlation was seen between SASH and language preference (0.75, <0.0001) and place of birth (0.70, <0.0001). Increased odds of severe ambulatory disability was associated: with being male, longer disease duration, education of high school or less (3.90, 95%CI 0.33-45.65), household income <$60,000 (3.22, 95%CI 0.26-39.75), and acculturation to US culture (4.041, 95%CI 0.79-20.62) after adjustment. EDSS also increased with acculturation to US (Beta 0.53, p=0.05) and low income (Beta 0.80, p=0.02) using adjusted linear regression.
Conclusions
Our study reveals insights into early disability patterns among diverse Latinx heritage, in the context of SES and cultural integration differences defined by strong acculturation measures. Preservation of Latinx cultural heritage in the US could have the capacity to alter disease severity and be protective in Latinx with MS. Further sociocultural investigations are warranted.
