  abstract     = {{Setting: Subnational, population-based
birth cohort studies (n = 45) in 23 low-and
middle-income
countries (LMICs) spanning 2000–2021.
Population: Liveborn infants.
Methods: Subnational, population-based
studies with high-quality
birth outcome
data from LMICs were invited to join the Vulnerable Newborn Measurement
Collaboration. We defined distinct newborn types using gestational age (preterm
[PT], term [T]), birthweight for gestational age using INTERGROWTH-21st
standards
(small for gestational age [SGA], appropriate for gestational age [AGA] or large
for gestational age [LGA]), and birthweight (low birthweight, LBW [<2500 g], non-
LBW) as ten types (using all three outcomes), six types (by excluding the birthweight
categorisation), and four types (by collapsing the AGA and LGA categories). We defined
small types as those with at least one classification of LBW, PT or SGA. We
presented study characteristics, participant characteristics, data missingness, and
prevalence of newborn types by region and study.
Results: Among 541 285 live births, 476 939 (88.1%) had non-missing
and plausible
values for gestational age, birthweight and sex required to construct the newborn
types. The median prevalences of ten types across studies were T+AGA+nonLBW
(58.0%), T+LGA+nonLBW (3.3%), T+AGA+LBW (0.5%), T+SGA+nonLBW
(14.2%), T+SGA+LBW (7.1%), PT+LGA+nonLBW (1.6%), PT+LGA+LBW (0.2%),
PT+AGA+nonLBW (3.7%), PT+AGA+LBW (3.6%) and PT+SGA+LBW (1.0%). The
median prevalence of small types (six types, 37.6%) varied across studies and within
regions and was higher in Southern Asia (52.4%) than in Sub-Saharan
Africa (34.9%).
Conclusions: Further investigation is needed to describe the mortality risks associated
with newborn types and understand the implications of this framework for local
targeting of interventions to prevent adverse pregnancy outcomes in LMICs.}},
