Rat pups exposed to tobacco smoke are at higher risk of developing metabolic disease
While many parents-to-be are aware that the health of their baby starts before they've actually arrived into the world, recent research reveals that "harm" (i.e., tobacco smoke, dirty air, poor nutrition, even preeclampsia) may not present itself disease-wise until well into adulthood or when a second harmful "hit" triggers the individual's susceptibility.
The results were announced at the Pediatric Academic Societies conference in Vancouver, British Columbia in May by Lisa Joss-Moore, Ph.D., University of Utah Department of Pediatrics.
"We're focusing on how certain prenatal events can cause you to develop lung disease and metabolic syndromes such as obesity, hypertension, diabetes and fatty liver," explains Joss-Moore, whose research reveals new insights into the molecular and structural changes occurring and possible targeted intervention preventing later-in-life diseases.
Results from her studies involving cigarette smoke revealed that rat pups exposed to tobacco smoke while in utero but not postnatally (equivalent age of infant/toddler stage) were at a higher risk of developing metabolic disease and a change in lung structure and function later in life (i.e., respiratory issues).
"People have known that smoking while pregnant is not necessarily good for the baby, but people still do it. There's this assumption that the baby is insulated from major harm, which isn't true," says Joss-Moore, whose research is part of a 20-year-old field known as The Developmental Origins of Health and Disease.
