Gaining too much weight during pregnancy may contribute to mothers becoming obese and can endanger their babies. Now researchers have devised a low-cost way to help keep pregnant women on track. In a study, mothers-to-be discussed with a dietitian the food and lifestyle changes they could make during pregnancy, as well as weight-gain goals appropriate for their body sizes. Then, at each routine obstetrical appointment, participants charted their weight gain and received feedback on it from a health care provider. A control group of pregnant women got standard prenatal care. The mamas who watched their weight gained fewer pounds, gave birth to babies who weighed less, and had fewer cesarean sections than those receiving standard care. Note, though, that many moms-to-be need to make sure they gain enough weight (see table, below).
