A study conducted by Public Health Wales among adolescents and adults aged 16 to 65 in Wales, and relayed by the site PsyPostthus suggests that “negative childhood experiences”, such as abuse and neglect (both physical and emotional), mental illness and substance abuse at home, witnessing domestic violence or Having an incarcerated parent can be factors in obesity in adulthood.

Eating in response to negative emotions
