A new study explores the obesity link between grandparent and grandchild. The findings of the study are published in Pediatric Obesity.
Obesity is known to cluster in families, but most studies to date are limited to two generations.
The study found a consistent relationship between waist circumference in maternal grandmother and grandchild, with no relationship seen in other lineages.
The results may suggest an intrauterine or environmental effect, with potential public health and clinical implications.
"These findings may have practical implications for family interventions at a time of global challenge in combating obesity," said senior author Dr. Cecily Kelleher, of University College Dublin, in Ireland.
"But they also emphasize the need to understand in scientific terms cross-generation transmission of non-communicable disease risk."
