Stroke is the leading cause of adult disability in the US and a leading cause of death. Mexican Americans (MA), the largest subgroup of Hispanic Americans, have a substantially higher stroke risk than European Americans, especially at younger ages where the risk is more than double. Given the greater risk and earlier onset, the impact of stroke is disproportionately experienced by MAs. Reasons for increased stroke risk in MAs are poorly understood. More than half of ischemic stroke patients have sleep apnea, a very common and important risk factor for stroke and potentially a risk factor for poor stroke outcome. No published studies have established the prevalence of sleep apnea in MAs to discern sleep apnea's contribution to excess stroke burden in this population. Small studies conducted in academic medical centers have suggested that stroke patients with sleep apnea have particularly poor stroke outcomes, but population-based studies in diverse populations are lacking. The current application seeks to investigate health disparities related to sleep apnea in stroke patients in order to understand the marked ethnic differences in stroke. This research will inform the development of interventions to prevent or treat sleep apnea in MAs, which will reduce the ethnic stroke disparity.
