Insights
This study compared growth and metabolic status in preterm (PT) and full-term (FT) small for gestational age (SGA) babies. While most SGA infants achieved catch-up growth, prematurity combined with intrauterine growth retardation (IUGR) impacted auxological outcomes.
Area of Science:
- Pediatrics
- Neonatology
- Endocrinology
Background:
- Small for gestational age (SGA) infants present unique auxological and metabolic challenges.
- Intrauterine growth retardation (IUGR) is a significant factor influencing infant development.
- Understanding the long-term outcomes for SGA infants is crucial for appropriate clinical management.
Purpose of the Study:
- To compare the auxological and metabolic status of preterm (PT) and full-term (FT) SGA babies from birth to two years.
- To investigate the role of IUGR in the auxological and metabolic outcomes of SGA infants.
Main Methods:
- A cohort of 44 SGA infants (22 FT, 22 PT) was followed for two years with six-monthly assessments.
- Anthropometric measurements (weight, length) and metabolic markers (glucose, insulin, total cholesterol, triglycerides) were collected.
- Homeostatic model assessment for insulin resistance (HOMA-IR) was used to evaluate insulin sensitivity.
Main Results:
- Both PT and FT SGA infants showed significant growth in the first six months, with weight gain slowing in PT infants between 6-12 months.
- Catch-up growth was observed in 90% of FT and 87% of PT SGA infants by 24 months.
- Insulin levels and HOMA-IR decreased over time in both groups, particularly between 6-12 months. PT SGA infants with IUGR had smaller size, lower growth velocity, and higher initial insulin/HOMA-IR compared to FT SGA without IUGR.
Conclusions:
- No significant differences in auxological and metabolic parameters were found between PT and FT SGA infants.
- Prematurity combined with IUGR is a significant factor influencing auxological outcomes in SGA infants.
- The timing of auxological follow-up for SGA subjects should consider the presence of prematurity and IUGR.
Objective:
To compare auxological and metabolic status of preterm (PT) and fullterm (FT) small for gestational age (SGA) babies from birth until age 2 years and to study the role of intrauterine growth retardation (IUGR) in auxological and metabolic outcome in SGA babies.
Methods:
We enrolled 44 SGA babies (22 FTs, 22 PTs) followed up six monthly. Anthropometric and metabolic measurements (fasting glucose, basal insulin level, total-cholesterol, triglycerides) were performed. HOMA-IR was selected to assess insulin sensitivity.
Results:
Both FTs and PTs from birth to age 6 months showed a significant increase in weight and length; the weight gain decreased from 6 to 12 months only in PTs. At 24 months, we observed catch-up growth in 90% of FTs and 87% of PTs. Insulinemia and HOMA-IR decreased from birth to 24 months, in particular between 6 and 12 months. PTs SGA with IUGR were significantly smaller than FTs SGA without IUGR (p = 0.01) and showed a lower length growth velocity. Moreover they showed also higher insulin levels and HOMA-IR at birth; these values decreased at 12 and 24 months.
Conclusions:
Our study showed no significant difference between PTs and FTs SGA in auxological and metabolic parameters. However, prematurity with IUGR proved to be a significant factor that should be considered in the timing of auxological follow-up of SGA subjects.
