  • A Norwegian study suggests a link between longer exclusive breastfeeding and fewer ADHD symptoms in children by age 8.
  • The research analyzed data from over 37,000 families, tracking breastfeeding duration and later attention development.
  • While the study indicates a correlation, researchers emphasize that ADHD is complex and influenced by genetics and other factors, and breastfeeding is not a guaranteed prevention.

New research from Norway indicates that the duration of exclusive breastfeeding in infancy may play a role in a child's attention development later in life. The study, published in the journal Biological Psychiatry, found a correlation between longer periods of exclusive breastfeeding and a reduced likelihood of children exhibiting symptoms of Attention Deficit Hyperactivity Disorder (ADHD) by the age of eight.

The longer the duration of exclusive breastfeeding, the less likely children are to exhibit ADHD symptoms before the age of 8.

— Study FindingSummarizing the core result of the Norwegian research.

Researchers from the University of Bergen analyzed data from the 'Norwegian Mother, Father, and Child Cohort Study,' involving over 37,600 families. Mothers provided information on their breastfeeding practices, including exclusive breastfeeding and mixed feeding, approximately six months after childbirth. This data allowed the study's authors to estimate the duration of exclusive breastfeeding for each child.

Any form of breastfeeding was associated with lower ADHD symptom levels, but as the feeding time increased, the degree also increased.

The analysis revealed that children who were exclusively breastfed for longer periods showed lower levels of ADHD symptoms at ages three, five, and eight. The study noted that any form of breastfeeding was associated with lower ADHD symptom levels, but this association became more pronounced with increased duration. The upper limit for exclusive breastfeeding duration observed in the study was six months.

ADHD is a complex neurodevelopmental disorder, and genetic factors remain the most significant influencing factor.

— Study ResearchersEmphasizing that breastfeeding is not the sole determinant of ADHD.

Scientists involved in the research suggest that breast milk contains crucial components like long-chain fatty acids, amino acids, antibodies, and beneficial bacteria that support brain growth and immune system development. However, they caution that the relationship between breastfeeding and ADHD is complex and could be influenced by multiple factors. The study is observational, meaning it shows an association rather than a direct cause-and-effect relationship, and researchers stress that genetic factors remain the primary influence on ADHD, alongside various biological and environmental factors.

This study is only an observational study and does not mean that breastfeeding can prevent hyperactivity disorder.
