Conclusion : Positive clinical ly meaningful effects ( > 5 points ) are seen to an age of 36 months , but are no longer present at 5 years
Objective : To determine in a systematic review , whether interventions for infant development that involve parents , improve neurodevelopment at 12 months corrected age or older .
Minimizing adverse effects of low birthweight: four-year results of an early intervention program.
The outcome of an early intervention program for low-birthweight ( LBW ) infants was examined in this study . The intervention consisted of 11 sessions , beginning during the final week of hospitalization and extending into the home over a 3-month period . The program aim ed to facilitate maternal adjustment to the care of a LBW infant , and , indirectly , to enhance the child 's development .  Neonates weighing less than 2,200 grams and under 37 weeks gestational age were r and omly assigned to experimental or control conditions . A full-term , normal birthweight ( NBW ) group served as a second control . 6-month analyses of dyads who completed all assessment s over a 4-year period ( N 's = 25 LBW experimental , 29 LBW control , and 28 NBW infant-mother dyads ) showed that the experimental group mothers reported significantly greater self-confidence and satisfaction with mothering , as well as more favorable perception of infant temperament than LBW control group mothers . A progressive divergence between the LBW experimental and LBW control children on cognitive scores culminated in significant group differences on the McCarthy GCI at ages 36 and 48 months , when the LBW experimental group caught up to the NBW group . Possible explanations for the observed delay in the emergence of intervention effects on cognitive development and the mediating role of favorable mother-infant transactional patterns are discussed in light of recent evidence from the literature
