In 2018, over 40% of the US adult population was considered obese (BMI of 30 or higher), up from 30% in 2000. Almost 10% of adults are considered severely obese (BMI of 40 or higher). Obesity among women of childbearing age is also steadily increasing, rising from just shy of 24% in 2008, to almost 31% in 2018. Unfortunately, researchers are finding that going into pregnancy at an unhealthy weight may increase the health risks for both mom and the baby, and the number of people considered obese is still climbing.

In addition to other health risks, a study in the journal Obesity Reviews suggests that the children of mothers who are obese during pregnancy may be at increased risk of various psychological disorders. These conditions can include cognitive problems and symptoms of attention deficit hyperactivity disorder in childhood, eating disorders in adolescence, and even psychotic disorders in adulthood.
