如果缺氧會影響大腦發育，那麼是否自幼生活在高海拔地區的人智力也會較低？有無相關研究？

之前看過一個紀錄片，講的就是高海拔地區（5000m以上）生活的藏族人身體給養功能和內地人的差別。

結論是：由於長期生活在高海拔地區，他們的血液中的血紅素要遠遠高於內地的人，也就是運輸氧氣的能力要遠遠高於內地人。所以題主所說的缺氧問題，在他們身上並不存在。

但是這也造成一個問題，這些人下到內地時會得低地病。。。

Denis Jourdanet (1815–1892) and the early recognition of the role of hypoxia at high altitude

Denis Jourdanet (1815–1892) was a French physician who spent many years in Mexico studying the effects of high altitude. He was a major benefactor of Paul Bert (1833–1886), who is often called the father of high-altitude physiology because his book La pression barométrique was the first clear statement that the harmful effects of high altitude are caused by the low partial pressure of oxygen.

However, Berts writings make it clear that the first recognition of the critical role of hypoxia at high altitude should be credited to Jourdanet. Jourdanet noted that some of his patients at high altitude had features that are typical of anemia at sea level, including rapid pulse, dizziness, and occasional fainting spells.

These symptoms were correctly attributed to the low oxygen level in the blood and he coined the terms 「anoxyhémie」 and 「anémie barométrique」 to draw a parallel between the effects of high altitude on the one hand and anemia at sea level on the other. He also studied the relations between barometric pressure and altitude, and the characteristics of the native populations in Mexico at different altitudes.

Jourdanet believed that patients with various diseases including pulmonary tuberculosis were improved if they went to altitudes above 2,000 m. This led him to recommend 「aérothérapie」 in which these patients were treated in low-pressure chambers. Little has been written about Jourdanet, and his work deserves to be better known.
