The relationship between altitude of residence and child linear growth is studied using data for 630,499 children below age 5 years born between 1992 and 2016, as recorded in 47 countries at elevations ranging from − 377 to 4498 m above sea level. Regressions are used to measure the role of household, community, and environmental factors in explaining an observed altitude effect on linear growth. Controlling for birth year and country effects, and a range of factors correlated with altitude and associated with nutrition outcomes, for each 1000 m gain in elevation, height for age z score (HAZ) declines by 0.195 points on average. Country-specific estimates of the association vary and include positive associations. Results highlight the potential links between developmental risks for children and features of their physical environment.

使用 1992 年至 2016 年间出生的 630,499 名 5 岁以下儿童的数据研究了居住海拔高度与儿童线性增长之间的关系，这些数据记录在 47 个国家海拔从 - 377 到 4498 米的海拔范围内。回归用于衡量家庭、社区和环境因素在解释观察到的海拔对线性增长的影响方面的作用。控制出生年份和国家效应，以及一系列与海拔高度相关和营养结果相关的因素，海拔每增加 1000 米，年龄 z 得分 (HAZ) 的身高平均下降 0.195 分。该关联的特定国家/地区估计各不相同，包括正关联。结果突出了儿童发育风险与其物理环境特征之间的潜在联系。
