Newborns at higher altitudes have up to 37 percent higher mortality rates

image: Adjusted hazard ratios of the incidence rate of death per each altitude stratum according to three mixed-effects multivariate Cox proportional hazards models, considering the reference an altitude of the health care facility where neonates were attended of <80m. Estimated hazard ratios from mixed-effects multivariate Cox proportional models. All models (1, 2 and 3) estimated fixed effects for next individual variables: gestational age, birth weight, Apgar scale at five minutes, and comorbidities; and random effects for contextual variables in this way: (i) administrative planning areas, type of health care facility, and level of care in Model 1, (ii) administrative planning areas, and level of care in Model 2; and (iii) level of care in Model 3. view more

Newborns at higher altitudes have up to 37 percent higher mortality rates, perhaps because of lower availability of blood oxygen, vitamins and minerals.
