Early intervention programmes for preterm infants have a positive influence on cognitive and motor outcomes during infancy, with the cognitive benefits persisting into pre-school age. There is a great deal of heterogeneity between studies due to the variety of early developmental intervention programmes trialled and gestational ages of the preterm infants included, which limits the comparisons of intervention programmes. Further research is needed to determine which early developmental interventions are the most effective at improving cognitive and motor outcomes, and on the longer-term effects of these programmes.
The effects of an early developmental mother-child intervention program on neurodevelopment outcome in very low birth weight infants: a pilot study.
Several studies report increased minor neurodevelopment dysfunctions in children born very low birth weight (VLBW). Usefulness of preventive early intervention programs to improve neurodevelopment outcome of VLBW infants is still under investigation.
                To evaluate the effects of an early post-discharge developmental mother-child intervention program on neurodevelopment outcome at 36 months in VLBW infants.
                Prospective study.
                36 VLBW infants ([mean (S.D.)] birthweight=864 g (204 g); gestational age=27.9 weeks (2.4 weeks)), consecutively born January-August 2001, randomized in intervention and control groups.
                Neurodevelopment assessment at 36 months of chronological age with use of the Griffiths Mental Development Scale and related subscales.
                At 36 months of chronological age, as compared to controls, children in intervention group exhibited higher scores in personal-social subscales ([mean (S.D.)]=101.4 (9.3) vs. 92.9 (12.1), P=0.02), eye-hand coordination (92.7 (4.5) vs. 87.1 (9.9), P=0.041), practical reasoning (98.6 (8.2) vs. 89.4 (10.1), P=0.01). Development Scale were 97.6 (5.5) and 92.4 (9.9), respectively, in intervention and control groups (P=0.074).
                Early post-discharge developmental mother-child intervention program may have a positive effect on later neurodevelopment outcome of VLBW children.
