Elevated body roundness index and epilepsy prevalence: a cross-sectional study.

Area of Science:

• Neurology
• Metabolic Health
• Epidemiology

Background:

• Obesity and epilepsy share a complex, bidirectional relationship.
• Body Mass Index (BMI) is a common metric but doesn't detail fat distribution.
• The Body Roundness Index (BRI) specifically measures abdominal adiposity.

Purpose of the Study:

• To investigate the association between BRI and epilepsy prevalence.
• To determine if abdominal fat distribution is a significant factor in epilepsy.

Main Methods:

• Analysis of 17,914 adults from the NHANES 2013-March 2020 dataset.
• Logistic regression modeling of BRI (continuous and tertiles) against prevalent epilepsy.
• Sensitivity analyses excluding users of specific antiepileptic drugs (valproate, carbamazepine).

Main Results:

• A significant positive association was found between higher BRI and increased odds of prevalent epilepsy (OR per unit: 1.08, P=0.03).
• The highest tertile of BRI (Q3) showed significantly higher epilepsy odds compared to the lowest (Q1) (OR: 1.73, P=0.03).
• Results remained consistent after sensitivity analyses.

Conclusions:

• Elevated abdominal adiposity, indicated by higher BRI, is associated with a greater prevalence of epilepsy.
• These findings suggest abdominal fat distribution may play a crucial role in epilepsy.
• Further prospective studies are warranted to confirm these associations.
