Thus, stroke prevention and treatment at high altitudes are challenging. We conducted a cross-sectional study to estimate the prevalence of stroke, the detection rate of individuals at high risk of stroke and the risk factors for stroke in the Qinghai-Tibet Plateau in China, a high altitude plateau that inhabits approximately 15 million people.<h4>Design</h4>A population-based cross-sectional study in the Qinghai-Tibet Plateau.<h4>Setting</h4>Data were collected from participants through face-to-face screening using a primary screening table. The table relied on the China National Stroke Screening and Prevention Project.<h4>ParticipantsBMJ openPrevalence of stroke and associated risk factors: a population-based cross-sectional study from the Qinghai-Tibet Plateau of China.PMC96852682019-ZJ-7051Li ZJi WHu QFan QfalsePrevalence of stroke and associated risk factors: a population-based cross-sectional study from the Qinghai-Tibet Plateau of China.<h4>Background and objectives</h4>The epidemiology of stroke at high altitudes has not been extensively studied, especially at heights of 4000 m and above.
