(2001), the
head circumference of ELBW infants was smaller than that of the term infant by 1.8 cm, and the infants were 5.8 cm shorter and 5.8 kg lighter than the adolescent born at term.
For
head circumference, the risk rose nine per cent for every 1.5 centimetre size increase.
Our study also found that maternal ghrelin concentration was positively associated with baby's
head circumference (and therefore brain development).
"Prenatal alcohol exposure was not related to weight or body mass index at 7.5 or 14 years, suggesting that the effects on height and
head circumference were not attributable to poor maternal nutrition," the researchers reported in their poster presentation.
However, the researchers noted that when they added infant
head circumference to the model, the strength of the relationship between cocaine exposure and mental development at 24 months decreased slightly, implying that "some of the negative effects of cocaine exposure on cognitive outcome were mediated through smaller
head circumference at birth."
Head circumference was measured at all ages and the Wechsler Intelligence Scale for Children individually administered at age 7.
Pregnant women who use cocaine or marijuana are more likely to give birth to infants with lower birth weight, decreased length, or smaller
head circumference, says a study funded by the National Institute on Drug Abuse (NIDA).
Body weight, length and
head circumference at birth in a cohort of Turkish newborns.
In this study, we measured the crown-heel length and
head circumference of term newborns for creating gender specific centile charts for newborns born at Government Medical College, Kottayam, Kerala.
The finding that some children born with microcephaly went on to develop normal
head circumference by age 1 means that "microcephaly is not necessarily static," Nielsen-Saines said.
These include increased
head circumference, sunsetting eyes, veins on the head, separated skull bones and at times, vomiting and shivering.
