Insights

Short stature is common in preterm infants, especially those with growth restraint. Systemic steroids increase risk, while breastfeeding may be protective for growth outcomes.

Area of Science:

  • Pediatrics
  • Neonatology
  • Growth and Development

Background:

  • Preterm birth is associated with various developmental challenges.
  • Children born preterm, particularly those small-for-gestational age (SGA) or with ex utero growth restraint (GR), face increased risks of growth abnormalities.
  • Understanding long-term growth trajectories and identifying associated risk factors is crucial for early intervention.

Purpose of the Study:

  • To assess growth patterns in very preterm infants up to 5 years of age.
  • To specifically evaluate growth in infants born SGA or with ex utero GR.
  • To identify key risk factors contributing to short stature at 5 years of age.

Main Methods:

  • A population-based cohort study (EPIPAGE) included children born before 33 weeks gestation.
  • Short stature was defined as height <-2SD using WHO growth curves.
  • Logistic regression analyses identified predictors of short stature, considering factors like SGA, maternal height, gestational age, and corticosteroid use.

Main Results:

  • Short stature affected 5.6% of very preterm children by age 5.
  • Among children with available data at 2 and 5 years, 24% born SGA and 36% with ex utero GR exhibited short stature.
  • Risk factors for short stature included SGA, maternal height ≤ 160 cm, gestational age <29 weeks, and systemic corticosteroid exposure.

Conclusions:

  • Short stature is a significant concern for children born preterm, with higher prevalence in those experiencing ex utero GR.
  • Systemic corticosteroid use demonstrates a lasting negative impact on growth, warranting cautious application.
  • Breastfeeding at discharge emerged as a protective factor against developing short stature.

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...
Signs of Puberty01:27

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
