Obesity is a physical marker of poor health, increasing the likelihood of various diseases. [2] Due to social constructs surrounding health, the belief that being skinny is healthy and discrimination against those perceived to be 'unhealthy', [3] people who are considered overweight or obese on the BMI scale face many social challenges.
In the United States the number of children a person has had is related to their risk of obesity. A woman's risk of obesity increases by 7% per child, while a man's risk increases by 4% per child.

Obesity has been associated with depression, likely due to social factors rather than physical effects of obesity. [15] However, it is possible that obesity is caused by depression (due to reduced physical activity or, in some people, increases in appetite). [54] Obesity-related disabilities may also lead to depression in some people. [54]
