Children gain weight when mothers work

ScienceDaily (Feb. 5, 2011) — Childhood obesity in the United States has more than tripled in the past three decades, and prior research has linked maternal employment to children's body mass index (BMI), a measure of their weight-for-height. A new study in the January/February issue of the journal Child Development has found that children's BMI rose the more years their mothers worked over their children's lifetimes.

The researchers found that the total number of years mothers were employed had a small but cumulative influence on their children's BMI, which, over time, can lead to an increase in the likelihood of overweight or obesity. The findings were strongest among children in 5th and 6th grades. Surprisingly, changes in children's physical activity, time spent unsupervised, and time spent watching TV didn't explain the link between maternal employment and children's BMI. Moreover, the time of day moms worked wasn't significantly associated with children's BMI.
