Many overweight moms and children tend to underestimate their weight, according to a new Columbia University study, indicating that heavy has become the new norm in many urban neighborhoods.

To come to their results, researchers questioned 111 moms and 111 children from New York City about their age, weight and income. Sixty-six percent of the moms were overweight or obese while 39 percent of children were too heavy. About 80 percent of participants were Hispanic, while the rest were either black, white or Asian.

When asked to estimate their own weight, 82 percent of obese women believed they weighed less than they did, while 42.5 percent of overweight women did the same. In addition, 86 percent of heavy children underestimated their weight. However, while almost half of moms with overweight children thought their kids were at a healthy body mass index, 41 percent of children thought their moms should lose weight.

Children who are overweight are considerably more likely to be obese as adults, according to the Centers for Disease Control and Prevention, a problem that could lead to a number of diseases and raise health insurance rates. The agency report[s] that one study discovered that 80 percent of children who were overweight between the ages of 10 and 15 were obese by 25.
