Preterm infants may develop altered adiposity, a risk factor for metabolic syndrome. The aim was to evaluate if body composition and blood pressure were altered in a cohort of children born preterm followed up to prepubertal age. Observational, longitudinal, explorative study. Forty children born preterm underwent growth and body composition assessment by an air displacement plethysmography system at term c.a. and at 5 years. BMI, skinfold thicknesses and blood pressure were further measured at 5 years. Inclusion criteria were birth weight <1500 g and gestational age <32 weeks. Exclusion criteria were congenital/chromosomal or surgical diseases. Forty-three healthy children born at term were the reference group. At term c.a. preterm children were lighter (2455 +/- 484 g vs 3247 +/- 345 g; p<0.001) and shorter (45.6 +/- 3.4 cm vs 49.1 +/- 2.3 cm; p<0.001) than children born at term and their fat mass was higher (14.8% vs 8.6%; p=0.02). At 5 years of life, weight and height of children born preterm were lower than those of their counterpart (18.328 +/- 3.01 vs 20.302 +/- 3.01 g; p=0.008 and 109.7 +/- 6.5 vs 112.7 +/- 4.3 cm; p=0.02, respectively). No difference in percentage of fat mass was detected. Abdominal, subscapular and suprailiac skinfolds (mm) were larger in the preterm group (6.9 +/- 3.6 vs 5.3 +/- 2.8, p=0.002; 6.5 +/- 2.8 vs 5.0 +/- 1.6, p=0,01 and 11.8 +/- 4.3 vs 9.3 +/- 3.8, p=0,01, respectively). Diastolic pressure (mmHg) was higher in the preterm group (62.2 vs 57.5, p=0.01). At prepubertal age children born preterm tend towards a greater truncal adiposity and increased values of diastolic pressure which might have adverse consequences for later health.
Obiettivi: valutare possibili alterazioni della composizione corporea e della pressione arteriosa in una coorte di ex-pretermine a 5 anni di età. Metodi: studio osservazionale longitudinale, esplorativo. Quaranta neonati pretermine venivano sottoposti a valutazione antropometrica e della composizione corporea tramite pletismografo ad aria a 40 settimane di età corretta e a 5 anni. A 5 anni venivano inoltre misurate pressione arteriosa e pliche cutanee e calcolato il BMI. Criteri di inclusione per i neonati prematuri: peso inferiore a 1500 g, età gestazionale alla nascita inferiore a 32 settimane. Criteri di esclusione: anomalie congenite/cromosomiche e patologie chirurgiche. Quarantatre neonati sani a termine costituivano il gruppo di riferimento. Risultati: al presunto termine, i nati prematuri presentavano peso e lunghezza inferiori ai controlli (18.328±3.01 vs 20.302±3.01 g; p=0.008 e 109.7±6.5 vs 112.7±4.3 cm; p=0.02, rispettivamente), mentre non venivano rilevate differenze nella percentuale di massa grassa. Le pliche addominale, sottoscapolare e sacroilaca (mm) risultavano maggiori nei bambini nati prematuri rispetto ai controlli (6.9±3.6 vs 5.3±2.8, p=0.002; 6,5±2,8 vs 5.0±1.6, p=0,01 e 11.8±4.3 vs 9.3±3.8, p=0,01, rispettivamente). I nati prematuri presentavano inoltre valori maggiori di pressione diastolica (62.2 vs 57.5 mmHg, p=0.01). Conclusioni: In età prepubere, i bambini prematuri presentavano maggiore adiposità truncale e pressione diastolica più elevata, con possibili effetti negativi sulla salute a distanza

Abstract
Preterm infants may develop altered adiposity, a risk factor for metabolic syndrome. The aim was to evaluate if body composition and blood pressure were altered in a cohort of children born preterm followed up to prepubertal age. Observational, longitudinal, explorative study. Forty children born preterm underwent growth and body composition assessment by an air displacement plethysmography system at term c.a. and at 5 years. BMI, skinfold thicknesses and blood pressure were further measured at 5 years. Inclusion criteria were birth weight <1500 g and gestational age <32 weeks. Exclusion criteria were congenital/chromosomal or surgical diseases. Forty-three healthy children born at term were the reference group. At term c.a. preterm children were lighter (2455 +/- 484 g vs 3247 +/- 345 g; p<0.001) and shorter (45.6 +/- 3.4 cm vs 49.1 +/- 2.3 cm; p<0.001) than children born at term and their fat mass was higher (14.8% vs 8.6%; p=0.02). At 5 years of life, weight and height of children born preterm were lower than those of their counterpart (18.328 +/- 3.01 vs 20.302 +/- 3.01 g; p=0.008 and 109.7 +/- 6.5 vs 112.7 +/- 4.3 cm; p=0.02, respectively). No difference in percentage of fat mass was detected. Abdominal, subscapular and suprailiac skinfolds (mm) were larger in the preterm group (6.9 +/- 3.6 vs 5.3 +/- 2.8, p=0.002; 6.5 +/- 2.8 vs 5.0 +/- 1.6, p=0,01 and 11.8 +/- 4.3 vs 9.3 +/- 3.8, p=0,01, respectively). Diastolic pressure (mmHg) was higher in the preterm group (62.2 vs 57.5, p=0.01). At prepubertal age children born preterm tend towards a greater truncal adiposity and increased values of diastolic pressure which might have adverse consequences for later health.File | Dimensione | Formato | |
