Antioxidant defense and oxidative damage vary widely among high‐altitude residents
OBJECTIVES: People living at high altitude experience unavoidable low oxygen levels (hypoxia). While acute hypoxia causes an increase in oxidative stress and damage despite higher antioxidant activity, the consequences of chronic hypoxia are poorly understood. The aim of the present study is to assess antioxidant activity and oxidative damage in high-altitude natives and upward migrants. METHODS: Individuals from two indigenous high-altitude popu…
Elevated pulmonary artery pressure among Amhara highlanders in Ethiopia
OBJECTIVE: Pulmonary arterioles respond to hypoxia with constriction that raises vascular resistance and pulmonary artery blood pressure. The response is sustained indefinitely by the chronic hypoxia of high-altitude residence among highlanders of European and Andean descent, but not Tibetans. The objective of this study was to identify the consequences of lifelong hypoxia exposure for the pulmonary vasculature among Amhara high-altitude natives …
Blood pressure variation among Ethiopians on the Simien Plateau
This report presents information on determinants of blood pressure variation in a rural sample of 263 Ethiopian highlanders 14-86 years of age, resident at 3530 m on the Simien Plateau. Mean systolic and diastolic blood pressures for males and females were 109/ 75 and 106/73, respectively, and there were no age differences. These findings confirmed that men and women can have low normal blood pressure throughout adulthood. Blood pressures increas…
