Geographic altitude and prevalence of underweight, stunting and wasting in newborns with the INTERGROWTH-21st standard
Journal Title: Jornal de Pediatria - Year 2019, Vol 95, Issue 3
Abstract
Objective To assess the prevalence and risks of underweight, stunting and wasting by gestational age in newborns of the Jujuy Province, Argentina at different altitude levels. Methods Live newborns (n=48,656) born from 2009–2014 in public facilities with a gestational age between 24+0 to 42+6 weeks. Phenotypes of underweight (weight/age), stunting (length/age) and wasting (body mass index/age) were calculated using INTERGROWTH-21st standards. Risk factors were maternal age, education, body mass index, parity, diabetes, hypertension, preeclampsia, tuberculosis, prematurity, and congenital malformations. Data were grouped by the geographic altitude: ≥2.000 or <2.000m.a.s.l. Chi-squared test and a multivariate logistic regression analysis were performed to estimate the risk of the phenotypes associated with an altitudinal level ≥2.000m.a.s.l. Results The prevalence of underweight, stunting and wasting were 1.27%, 3.39% and 4.68%, respectively, and significantly higher at >2.000m.a.s.l. Maternal age, body mass index >35kg/m2, hypertension, congenital malformations, and prematurity were more strongly associated with underweight rather than stunting or wasting at ≥2.000m.a.s.l. Conclusions Underweight, stunting, and wasting risks were higher at a higher altitude, and were associated with recognized maternal and fetal conditions. The use of those three phenotypes will help prioritize preventive interventions and focus the management of fetal undernutrition.
