To examine the relationship between child maltreatment and cognitive development in extremely low birth weight infants, adjusting for perinatal and parental risk factors.
A total of 352 infants with birth weight of <1000 g were followed prospectively for 4 years. The data were analyzed with regard to perinatal and parental risk factors and referrals for suspected child maltreatment to government agencies. Perinatal risk factors included birth weight, gestation, gender, periventricular hemorrhage, ventricular dilation, home oxygen requirement, and necrotizing enterocolitis. Parental risk factors included maternal age, race, marital status, education, and hospital insurance status. Cognitive z scores were calculated at 1, 2, and 4 years, and head circumference z scores were calculated at birth, 2 years, and 4 years.
Fifteen percent of infants were referred to child protective services for suspected child maltreatment. The adjusted general cognitive index at 4 years was significantly reduced in infants who were referred for neglect (-17.6; 95% confidence interval: -3.3, -31.9). Infants whose neglect was substantiated had a progressive decline in their cognitive function over time (cognitive z scores: -0.97, -1.37, and -2.05 standard deviations at 1, 2, and 4 years, respectively), compared with non-neglected infants (z scores: -0.04 to -0.36). They had a significantly smaller head circumference at 2 and 4 years but not at birth (adjusted z score at 4 years: -0.812; 95% confidence interval: -0.167, -1.458). Perinatal risk factors and physical disability were not related to maltreatment referral; only parental factors were independent predictors.
Childhood neglect is associated significantly with delayed cognitive development and head growth. Addressing risk factors antenatally and in early childhood may improve outcomes.
This research output has an Altmetric Attention Score of 18. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 14 May 2020.

#2,561,489
of 34,492,055 outputs
Outputs from Pediatrics
#6,350
of 22,652 outputs
Outputs of similar age
#2,651
of 60,149 outputs
Outputs of similar age from Pediatrics
#40
of 151 outputs
Altmetric has tracked 34,492,055 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 92nd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 22,652 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 47.4. This one has gotten more attention than average, scoring higher than 71% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 60,149 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 95% of its contemporaries.
We're also able to compare this research output to 151 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 71% of its contemporaries.
