Previous studies suggested a link between gestational diabetes in pregnant women and an increased risk of attention deficit hyperactivity disorder (ADHD) in their children. However, new research from National Cheng Kung University challenges this notion. Led by Professor Lai Jiazhen from the Department of Pharmacy and the Center for Population Health Data at the Institute of Clinical Pharmaceutical Technology, the study used real-world data from seven countries, including Taiwan, to investigate this relationship.
Contrary to previous findings, the study found that gestational diabetes does not elevate the risk of ADHD in children. This conclusion was drawn after analyzing health data from approximately 3.6 million mothers and children. The research employed a sibling control approach, accounting for family dynamics, environmental factors, genetics, and other variables. The findings, published in “Natural Medicine,” emphasize that gestational diabetes does not play a causal role in ADHD development.
According to Professor Lai, earlier studies often faced limitations such as small sample sizes or insufficient consideration of genetic and environmental influences. By utilizing extensive cross-national data, the study aimed to provide a clearer understanding of the relationship between gestational diabetes and ADHD, ultimately guiding future public health policies and treatment strategies.
The research underscores the importance of accurate causal inference methods in medical studies, aiming to prevent unwarranted stigma or guilt towards mothers and affected children.
