Summary: This study found an association between prenatal exposure to fine particulate matter (PM2.5) and small-for-gestational-age (SGA) birth and lower birthweight percentile. Comparing successive pregnancies in the same women, the study better controlled for confounding factors and strengthened the evidence for causal relationship between PM2.5 exposure and pregnancy outcomes.

Summary: This study reveals that small for gestational age (SGA) preterm infants with very low birth weight (VLBW) gradually develop a distinct gut microbiota profile in the early days of life, varying from appropriate for gestational age (AGA) preterm infants. Additionally, there is a noticeable separation in gut microbiota structure between the two groups on day 30.

Summary: This study aimed to assess neurocognitive function in adults born with low birthweight compared with controls and explore associations between neurocognitive function and psychopathology in these groups. The results showed that the very low birthweight group scored significantly lower than the control group on multiple neurocognitive measures, while the small for gestational age group scored lower on IQ and psychomotor speed. Adjusted for sex and parental socioeconomic status, lower IQ was associated with attention problems. These findings have important clinical implications.

Summary: This study compared the short-term neonatal outcomes of delayed cord clamping and early cord clamping in small for gestational age preterm infants, finding that delayed cord clamping was associated with reduced odds of mortality or major morbidity. Many benefits of delayed cord clamping in small for gestational age preterm infants were similar to those in non-small for gestational age preterm infants.

Summary: This study compared mortality and major morbidities between very preterm SGA and AGA neonates, and found that SGA neonates had higher odds of developing necrotizing enterocolitis, abnormal composite outcome, hypoglycemia, and anemia compared to AGA neonates.

Summary: There is a lack of research on the nonlinear associations between birth weight percentiles and cognitive performance in infancy. This study aims to investigate the culturally invariant, nonlinear associations of birth weight percentiles and gestational age with later cognitive performance.

Summary: This study evaluated the association between SGA severity and morbidity and mortality in very preterm infants. The results showed that an increase in weight was associated with decreased risk of major morbidity or mortality and other adverse outcomes. Additionally, symmetric growth restriction was not associated with neonatal outcomes.

Summary: This study aims to describe the linear growth trajectories of low birthweight small-for-gestational-age (SGA-LBW) infants during the first 6 months of life compared with appropriate-for-gestational-age LBW (AGA-LBW) infants. The results showed that SGA-LBW infants had slower linear growth, lower attained length, and lower LAZ score compared to AGA-LBW infants. Factors associated with poor catch-up growth in SGA-LBW infants included lower wealth quintiles, high birth order, home birth, male child, term delivery, non-exclusive breastfeeding, and pneumonia.

Summary: For children born very preterm between 2001 and 2015 in Taiwan, the improvement of maternal education levels and improvements in neonatal brain injury and mortality were temporally associated with trends of decreasing intellectual impairment at school age across all gestational age groups.

Summary: This study assesses the performance of two international birthweight standards in identifying perinatal morbidity and mortality indicators associated with small for gestational age infants at term. The results show that compared to INTERGROWTH-21st, GROW identifies more small for gestational age infants with adverse outcomes.

Summary: Among nonanomalous neonates, neither intrauterine nor birthweight-derived standards for small for gestational age accurately predicted neonatal morbidity and mortality, with no discriminatory ability at term. Intrauterine standards performed better than birthweight standards.

Summary: This study aims to evaluate the relationship between small for gestational age (SGA) and mortality and morbidity in Chinese preterm infants. The study found that the SGA group had increased risks of mortality and bronchopulmonary dysplasia (BPD) compared to the appropriate-for-gestation-age (AGA) group. The effects of SGA status on mortality and morbidity varied in different gestational age ranges.

Summary: This study aimed to investigate the association between antepartum stillbirth and the distribution of neonatal/fetal weight for different gestational ages. The study found a continuous association between fetal weight and the weight of antepartum stillbirth, which was influenced by gestational age. The highest risk of stillbirth occurred in fetuses with weights below the 1st percentile between 24 and 28 weeks' gestation.

Summary: This study analyzed the association of birthweight and gestational age with school entry, grade repetition, and school dropout. The results showed that low birthweight is negatively associated with school entry and age at school entry. Efforts to avoid low birthweights should be part of maternal and prenatal health care because the associated difficulties may be difficult to overcome later in the child's life.

Summary: This study investigated the predictors of small for gestational age (SGA) among women with type 2 diabetes in pregnancy who were treated with metformin. It was found that the presence of comorbidities and the use of metformin were predictive of SGA. Women with comorbidities who received metformin had a much higher risk of SGA compared to those without comorbidities.
