New York Times published an article on the findings from the study, Evaluation of linear growth at higher altitudes in the journal, Jama Pediatrics. Living at high altitudes may be associated with giving birth to smaller babies who grow more slowly through childhood. Researchers studied 964,299 children in 59 low- and middle-income countries in Asia, Africa, Eastern Europe, the Caribbean and Latin America. Among them, 106,441 lived above an altitude of 1,500 meters, or about a mile high. Researchers saw a direct relationship between height and altitude: beginning as low as 500 meters above sea level, the higher the altitude, the shorter the babies’ length at birth and the slower their growth up to 5 years old.
