Serious psychological distress and health outcomes for persons with epilepsy in poverty

Epidemiology literature demonstrates socioeconomic status as an important variable for outcomes in persons with epilepsy. However, no previous studies have analyzed the association between poverty and epilepsy in the United States. Forty-one percent (246/604) of persons with a history of epilepsy (PWHE) in the 2005 California Health Interview Survey (n=43,020) had an annual income <200% Federal Poverty Level (FPL), adjusted lifetime prevalence rate 0.5% [98.33% CI 0.4-0.7]. Four groups are presented in the analyses: (1) those with a history of epilepsy <200% FPL, (2) those with a history of epilepsy > or =200% FPL, (3) those not reporting a history of epilepsy <200% FPL and (4) those not reporting a history of epilepsy > or =200% FPL. PWHE in poverty reported significantly higher amounts of serious psychological distress, based on the validated Kessler 6 (K6) scale, than both non-epilepsy populations. After adjusting for demographics and other comorbid conditions, logistic regression analyses show PWHE in poverty are significantly more likely to report fair or poor self-rated health status when compared to the PWHE not in poverty and both non-epilepsy populations. PWHE in poverty are also more likely to report > or =14 generally unhealthy days and > or =14 physically unhealthy days in the past 30 days compared to the PWHE not in poverty and both non-epilepsy populations. Psychological well-being needs to be incorporated into any comprehensive treatment strategy for managing epilepsy.
