Postnatal Growth in a Cohort of Sardinian Intrauterine Growth-Restricted Infants

الملخص EN

Recent studies have shown that infants with intrauterine growth restriction (IUGR) undergo catch-up growth during infancy.

The aim of our study was to evaluate the postnatal growth in a cohort of IUGR infants born in a tertiary-level Obstetric University Hospital of Northern Sardinia.

An observational retrospective study was conducted on 12 IUGR (group A) and 12 control infants (group B) by measuring the anthropometric parameters of weight (W), length (L) and head circumference (HC) from birth to the 3rd postnatal year.

At birth, significant differences were found between group A and group B with regard to all the auxological parameters (W, mean 1846.6 versus 3170.8 g, p < 0.0001; HC, 30.1 versus 34.4 cm, p < 0.0001; L, mean 43.4 versus 49.4 cm, p < 0.0001).

During the 1st year, 8 of 12 (70%) IUGR infants exhibited a significant catch-up growth in the 3 anthropometric parameters and a regular growth until the 3rd year of follow-up.

The majority but not all infants born with IUGR in our series showed significant postnatal catch-up growth essentially during the first 12 months of life.

An improved knowledge of the causes of IUGR will help to develop measures for its prevention and individualized treatment.
