ABSTRACT: Peripheral neuropathy (PN) is a disorder of the peripheral nervous system associated with significant morbidity and mortality. PN is common among U.S. adults, even in the absence of diabetes, where it presents with sensory symptoms such as tingling, numbness, burning, pain, and sensory ataxia. Motor symptoms include muscle cramps, stiffness, weakness, and wasting. The overall prevalence of PN in the United States is 13.5% in adults with diabetes and 11.6% in adults without diabetes, clearly indicating that PN is a significant public health problem among U.S. adults. Poverty and low income have been associated with poor health outcomes. There are no published studies examining whether poverty income ratio is associated with the effect of PN on overall mortality among U.S. adults without diabetes. Using the socioecological model as the theoretical framework, the purpose of this longitudinal study was to examine whether poverty income ratio moderated the effect of PN on overall mortality. Secondary data from the National Health and Nutrition Examination Survey (NHANES) 1999-2015 dataset were analyzed using complex sample Cox regression analysis with the threshold for statistical significance taken at p p p
