PLEASANTON, CA – A new study published in the journal Obesity suggests that adequate breastfeeding and avoiding sugary drinks in early childhood may significantly reduce the risk of preadolescent obesity in children who were exposed to gestational diabetes (GDM) during pregnancy.
Researchers at Kaiser Permanente Northern California, led by Dr. Baiyang Sun, analyzed data from 850 mother-infant pairs where the mothers had GDM. They examined the impact of GDM severity, breastfeeding practices, and the consumption of sugary beverages on the children’s weight between the ages of 6 and 11.
The study revealed that a substantial portion of the children had weight issues: 17.6% were overweight, 18.2% had moderate obesity, and 7.6% had severe obesity.
The most significant finding was the protective effect of adequate breastfeeding combined with the avoidance of sugar-sweetened beverages (SSBs) and 100% fruit juice (FJ). Children who were adequately breastfed and did not consume SSBs or FJ had the lowest risk of obesity.
Conversely, children who were inadequately breastfed and consumed SSBs or FJ had a 55% higher risk (adjusted relative risk [aRR], 1.55) of obesity compared to those with adequate breastfeeding and no sugary drinks. Even children who were adequately breastfed but consumed sugary drinks showed a 50% increased risk (aRR, 1.50).
The risk of severe obesity was particularly striking. Children with inadequate breastfeeding and sugary drink consumption had a 3.8 times higher risk (aRR, 3.80) of severe obesity compared to those with adequate breastfeeding and no sugary drinks.
“BF adequacy and avoidance of sugary beverages in early life are modifiable lifestyle behaviors that may combat preadolescent obesity in infants exposed to GDM, suggesting potential longer-term benefits on child cardiometabolic health,” the authors concluded.
This research underscores the importance of early intervention and lifestyle choices in mitigating the long-term health risks associated with GDM exposure. The study highlights that encouraging adequate breastfeeding and limiting sugary drinks in early childhood can have a profound impact on preventing obesity in vulnerable populations.
