Two Birth Factors Linked to IQ Levels, Oxford Study Finds.

How Birth Conditions Shape Cognitive Development

According to TSN.ua: A team of international researchers has identified two birth-related factors that can significantly influence a person's cognitive development and academic performance: being born prematurely and having a low birth weight. The study, conducted by scientists at the University of Oxford, reveals that these factors may have lasting negative effects on intellectual growth.

Key Study Findings

Premature birth is defined as delivery before the 37th week of pregnancy. According to the research, individuals born early or with low birth weight tend to score an average of 10 points lower on IQ tests compared to those born full-term. This finding underscores the critical role that gestational age and newborn body weight play in a child's future development.

The researchers analyzed dozens of systematic reviews and hundreds of prior scientific studies, giving them a comprehensive view of the issue. The study found that children born significantly early face higher risks of health and developmental problems. This highlights the need for greater attention to these factors during pregnancy planning and in supporting maternal and child health.

These results emphasize the importance of timely medical monitoring during pregnancy and the need for support programs for mothers at risk of preterm birth or delivering low-weight babies. The findings may also encourage further research into the long-term effects of these factors on child development and strategies to reduce their negative impact.
