Gestational weight gain generally does not influence child cognitive development

29.02.2012
A child's cognitive development is not generally impacted by how much weight his or her mother gained during pregnancy, according to a study from Nationwide Children's Hospital. This is the first study to use methods controlling for the widest range of confounding factors when directly examining the association between gestational weight gain and childhood cognition.

Insufficient or excessive weight gain in pregnancy can have negative consequences for fetuses and children including infant mortality. The Institute of Medicine recently revised gestational weight gain guidelines, recommending that women gain weight within specific weight gain ranges for their Body Mass Index category. Yet little is known about the association between extremes of gestational weight gain and child cognition.

"One challenge for studies examining gestational weight gain and child outcomes is separating the effect of gestational weight gain from confounders," said Sarah A. Keim, PhD, principal investigator in the Center for Biobehavioral Health at The Research Institute at Nationwide Children's Hospital. "Confounders such as maternal intelligence, whether the family environment promotes cognitive development, family diet and exercise and some genetic factors can influence neurodevelopment postnatal and also gestational weight gain."

To address these gaps in data, Dr. Keim led a study to assess the association between gestational weight gain and the cognitive performance of children at 4 and 7 years of age. The study appears in the International Journal of Epidemiology.

Using data from the U.S. Collaborative Perinatal Project, Dr. Keim's team employed two statistical approaches. The more traditional approach adjusted for factors like the mother's weight before pregnancy, her race and the baby's sex. The other used a fixed-effects approach to control for all potential confounding factors that are shared among siblings, such as a proportion of genetic factors and parenting practices.

Findings showed that any observed detrimental influence of extremes of gestational weight gain on cognition can be explained by familial or shared genetic factors rather than gestational weight gain itself. Dr. Keim cautions that these results do not apply to preterm children and don't account for all possible confounding factors. "Strength of our approach is the potential for reduced bias in our estimates," said Dr. Keim. "However, this does not eliminate the possibility of residual confounding from factors siblings do not share. Our findings suggest that gestational weight gain is generally unassociated with child cognitive development."

Im Focus: Successfully Tested in Praxis: Bidirectional Sensor Technology Optimizes Laser Material Deposition

The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.

Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Im Focus: MPSD team discovers light-induced ferroelectricity in strontium titanate

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.

Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...

Im Focus: Determining the Earth’s gravity field more accurately than ever before

Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.

The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
