From The LA Times?..
Alright, you?ve heard your newborn bundle of joy?s lusty cry; you?ve counted his or her fingers and toes; you may just have learned the baby?s gender. So let?s not waste another minute before sucking the joy from this picture of blissful innocence and answering a key question about his or her health and appearance: Will he or won?t she be fat?
Noting that ?prevention of obesity should start as early as possible after birth,? international researchers have devised a checklist of factors that can be quickly toted up at a mother?s bedside to predict with moderate certainty ? an accuracy of between 71% and 85% ? her newborn?s prospects of becoming obese.
The resulting checklist, published Wednesday in the journal PLoS One, uses just six inputs to determine a newborn?s probability of remaining obese (in the absence of early intervention) throughout childhood and beyond: his or her parents? body-mass indices (BMI), the baby?s birth weight, the mother?s weight gain during pregnancy, the number of members in the baby?s household, the professional category of the baby?s mother, and whether mom smoked during pregnancy.
A child?s prospects of obesity were ?largely driven? by his or her parents? BMI, researchers found: If one or both were obese, the baby?s odds of joining them in that status increased steadily as a function of how obese, and whether one or both were obese. But other factors ? mom?s avoidance of tobacco while pregnant, a larger number of household members, a mother?s status as a professional rather than an unskilled worker ? could powerfully check the bad start that came from having an obese parent (or two).
Least likely to become obese was a baby born into a household of five people who weighed about 6.5 pounds (3 kg) at birth and had a normal-weight father and a professional mother of normal weight who didn?t smoke during pregnancy. This baby?s likelihood of becoming obese in childhood was calculated at 0.13%.
By contrast, a baby born at close to 9 pounds into a household of three, including an obese father and a mother with a BMI of over 35 who smoked during pregnancy and worked as a skilled manual laborer had a probability of childhood obesity of more than 77%.
Importantly, the researchers set out to include genetic variations that would help predict a baby?s prospects of accumulating too much fat. In the end, they found that none of the known genetic variations associated with obesity predicted a baby?s future girth as powerfully as the six factors listed above.
