Vulnerable newborn types: analysis of subnational, population-based birth cohorts for 541 285 live births in 23 countries, 2000–2021

Objective: To examine prevalence of novel newborn types among 541 285 live births in 23 countries from 2000 to 2021. Design: Descriptive multi-country secondary data analysis. 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], nonLBW) 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.The Children's Investment Fund Foundation, grant 2004-04670.

Injections during labor and intrapartum-related hypoxic injury and mortality in rural southern Nepal

Objective To estimate the association between unmonitored use of injections during labor and intrapartum-related neonatal mortality and morbidity among home births. Methods Recently delivered women in Sarlahi, Nepal, reported whether they had received injections during labor. Data on breathing and crying status at birth, time to first breath, respiratory rate, sucking ability, and lethargy were gathered. Neonatal respiratory depression (NRD) and encephalopathy (NE) were compared by injection receipt status using multivariate regression models. Results Injections during labor were frequently reported (7108 of 22 352 [31.8%]) and were predominantly given by unqualified village doctors. Multivariate analysis (excluding facility births and complicated deliveries) revealed associations with intrapartum-related NRD (relative risk [RR] 2.52; 95% CI, 2.29-2.78) and NE (RR 3.48; 95% CI, 2.46-4.93). The risks of neonatal death associated with intrapartum-related NRD (RR 3.78; 95% CI, 2.53-5.66) or NE (RR 4.47; 95% CI, 2.78-7.19) were also elevated. Conclusion Injection during labor was widespread at the community level. This practice was associated with poor outcomes and possibly related to the inappropriate use of uterotonics by unqualified providers. Interventions are required to increase the safety of childbirth in the community and in peripheral health facilities.

Incidence of and risk factors for neonatal respiratory depression and encephalopathy in rural Sarlahi, Nepal

OBJECTIVES: To characterize the incidence of, risk factors for, and neonatal morbidity and mortality associated with respiratory depression at birth and neonatal encephalopathy (NE) among term infants in a developing country. METHODS: Data were collected prospectively in 2002-2006 during a community-based trial that enrolled 23 662 newborns in rural Nepal and evaluated the impact of umbilical-cord and skin cleansing on neonatal morbidity and mortality rates. Respiratory depression at birth and NE were defined on the basis of symptoms from maternal reports and study-worker observations during home visits. RESULTS: Respiratory depression at birth was reported for 19.7% of live births, and 79% of cases involved term infants without congenital anomalies. Among newborns with probable intrapartum-related respiratory depression (N = 3465), 112 (3%) died before their first home visit (presumed severe NE), and 178 (5%) eventually developed symptoms of NE. Overall, 629 term infants developed NE (28.1 cases per 1000 live births); 2% of cases were associated with congenital anomalies, 25% with infections, and 28% with a potential intrapartum event. The incidence of intrapartum-related NE was 13.0 cases per 1000 live births; the neonatal case fatality rate was 46%. Infants with NE more frequently experienced birth complications and were male, of multiple gestation, or born to nulliparous mothers. CONCLUSIONS: In Sarlahi, the incidence of neonatal respiratory depression and NE, associated neonatal case fatality, and morbidity prevalence are high. Action is required to increase coverage of skilled obstetric/neonatal care in this setting and to evaluate long-term impairments. Copyright © 2011 by the American Academy of Pediatrics

Risk factors for neonatal mortality due to birth asphyxia in southern Nepal: A prospective, community-based cohort study

OBJECTIVE. Our goal was to identify antepartum, intrapartum, and infant risk factors for birth asphyxia mortality in a rural, low-resource, population-based cohort in southern Nepal. PATIENTS AND METHODS.Data were collected prospectively during a cluster-randomized, community-based trial evaluating the impact of newborn skin and umbilical cord cleansing on neonatal mortality and morbidity in Sarlahi, Nepal. A total of 23 662 newborn infants were enrolled between September 2002 and January 2006. Multi-variable regression modeling was performed to determine adjusted relative risk estimates of birth asphyxia mortality for antepartum, intrapartum, and infant risk factors. © 2008 by the American Academy of Pediatrics
