AI Article Synopsis

  • The study investigated adverse neonatal outcomes in children born to mothers with different eating disorders, including anorexia nervosa (AN), bulimia nervosa (BN), and eating disorder not otherwise specified (EDNOS).
  • It analyzed data from over 1.5 million births in Denmark from 1991 to 2015, comparing outcomes based on whether the eating disorder diagnosis was recent (within 2 years of conception) or past (over 2 years before conception).
  • Findings showed that recent eating disorders, especially AN, were linked to higher risks of low birthweight, small-for-gestational-age, and preterm birth, emphasizing the need for better prevention and monitoring of eating disorders during pregnancy.

Article Abstract

Objective: We examined the risk of adverse neonatal outcomes among children born to mothers with anorexia nervosa (AN), bulimia nervosa (BN), and eating disorder not otherwise specified (EDNOS).

Design: Cohort study.

Setting: Population-based using Danish national registers.

Population: We included 1 517 839 singletons born between 1991 and 2015 in Denmark.

Methods: For each ED subtype, we compared children born to mothers with a recent (≤ 2 years before conception and during pregnancy) or past (> 2 years before conception) diagnosis, with children born to mothers who had not been diagnosed with the ED of interest before the index delivery.

Main Outcome Measures: Using multinomial logistic regression, we estimated relative risk ratios (RRRs) and 95% confidence intervals (CIs) for gestational age, birthweight, weight-for-gestational age, low Apgar score, Caesarean section, congenital malformations and postpartum haemorrhage.

Results: Both recent and past AN were associated with increased risk of low birthweight (recent: RRR = 2.36 [95% CI = 1.76-3.18]; past: 1.22 [1.04-1.43]), small-for-gestational age (recent: 1.52 [1.01-2.26]; past: 1.37 [1.16-1.62]), and preterm birth (recent: 1.83 [1.37-2.45]; past: 1.17 [1.00-1.36]), with more pronounced risks in recent AN. Recent (but not past) BN was associated with increased risk of low Apgar score (1.44 [1.03-2.00]). Recent (but not past) EDNOS was associated with increased risk of SGA (1.53 [1.04-2.27]).

Conclusions: Children born to mothers with EDs have an increased risk of some adverse neonatal outcomes, with more pronounced risks in recent than past EDs. These results underscore the need for improved prevention of maternal EDs and enhanced monitoring throughout pregnancy to mitigate adverse outcomes.

Adverse birth outcome research case definitions associated with maternal HIV and antiretroviral drug use in pregnancy: a scoping review.

BMC Pregnancy Childbirth

December 2024

Department of Paediatrics & Child Health, Faculty of Medicine and Health Sciences, Stellenbosch University, Cape Town, South Africa.

Background: Adverse birth outcomes (preterm birth, low birth weight, small for gestational age, and stillbirth) seem to persist in infants born to people with HIV, even in the context of maternal antiretroviral therapy. However, findings have been disparate, inconclusive, and difficult to compare directly across settings, partly owing to variable outcome definitions. We aimed to collate, compare, and map existing adverse birth outcome definitions to inform a harmonized approach to universally measure these outcomes in studies including pregnant people with HIV.

Background: High fasting plasma glucose (HFPG) has been indicated as one of the important risk factors for cancers. This study aimed to estimate the disease burden of cancers attributable to HFPG in China from 1990 to 2021 and predict the burden until 2031.

Methods: The data of cancers attributable to HFPG were extracted from Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 project.

Background: Neonatal seizures are common with acute brain injury. Up to 25% of survivors develop postneonatal epilepsy. We hypothesized postneonatal epilepsy diagnosed by age 24 months would increase risk for early markers of neurobehavioral disorders than acute provoked neonatal seizures alone.
