Abstract
Introduction: birth size is affected by diverse maternal, environmental, social, and economic
factors. Aim: analyze the relationships between birth size—shown by the indicators small for
gestational age (SGA) and large for gestational age (LGA)—and maternal, social, and environmental
factors in the Argentine province of Jujuy, located in the Andean foothills. Methods: data was
obtained from 49,185 mother-newborn pairs recorded in the Jujuy Perinatal Information System (SIP)
between 2009 and 2014, including the following: newborn and maternal weight, length/height, and
body mass index (BMI); gestational age and maternal age; mother’s educational level, nutritional
status, marital status and birth interval; planned pregnancy; geographic-linguistic origin of surnames;
altitudinal place of birth; and unsatisfied basic needs (UBN). The dataset was split into two groups,
SGA and LGA, and compared with adequate for gestational age (AGA). Bivariate analysis (ANOVA)
and general lineal modeling (GLM) with multinomial distribution were employed. Results: for SGA
newborns, risk factors were altitude (1.43 [1.12–1.82]), preterm birth (5.33 [4.17–6.82]), older maternal
age (1.59 [1.24–2.05]), and primiparous mothers (1.88 [1.06–3.34]). For LGA newborns, the risk
factors were female sex (2.72 [5.51–2.95]), overweight (1.33 [1.22–2.46]) and obesity (1.85 [1.66–2.07]).
Conclusions: the distribution of birth size and the factors related to its variability in Jujuy are found
to be strongly conditioned by provincial terrain and the clinal variation due to its Andean location
