Związek między skumulowaną nierównością społeczną a epilepsją: badanie przekrojowe
Association between cumulative social disadvantage, as measured by the social determinants of health score, and epilepsy: a cross-sectional study
W skrócie
Badanie wykazało, że osoby żyjące w trudniejszych warunkach społecznych i ekonomicznych (takich jak bieda, brak dostępu do edukacji, mieszkanie w bezpiecznej okolicy) częściej chorują na epilepsję. Każdy dodatkowy punkt na skali trudnych warunków życia zwiększał szansę na epilepsję o 31 procent. Naukowcy przeanalizowali dane od ponad 13 tysięcy Amerykanów i stwierdzili, że osoby z epilepsją miały znacznie wyższe wskaźniki nierówności społecznej niż osoby zdrowe.

BACKGROUND: Social determinants of health (SDoH) shape access to care, health behaviors, and long-term outcomes, yet their cumulative relationship with epilepsy has not been well quantified. This study examined whether a composite SDoH score was associated with epilepsy in adults. METHODS: This cross-sectional study used data from the National Health and Nutrition Examination Survey 2013-2018. The SDoH score ranged from 0 to 8 and summarized eight unfavorable social conditions. Epilepsy was identified using medication-based ascertainment. Survey-weighted logistic regression models were applied to evaluate the association between SDoH score and epilepsy. Restricted cubic spline, subgroup, sensitivity, and receiver operating characteristic analyses were also performed. RESULTS: A total of 13,119 participants were included, of whom 114 had epilepsy. Participants with epilepsy had a higher mean SDoH score than those without epilepsy (3.41 ± 0.24 vs. 2.35 ± 0.06, P < 0.001). In the fully adjusted model, each 1-point increase in SDoH score was associated with 31% higher odds of epilepsy (OR 1.31, 95% CI 1.16-1.48). Compared with the low-score group (0-2), the adjusted odds ratios were 2.09 (95% CI 1.06-4.15) for scores of 3-5 and 2.67 (95% CI 1.34-5.33) for scores of 6-8. Spline analysis showed a significant overall association without evidence of nonlinearity. Adding SDoH components to demographic variables improved model discrimination (AUC 0.731 vs. 0.589, P for difference <0.001). CONCLUSION: Greater cumulative social disadvantage, as reflected by the SDoH score, was associated with higher odds of epilepsy.
