Being overweight or having obesity may increase the risk of several diseases, such as diabetes, heart disease, and some cancers, and may lead to short- and long-term health problems during pregnancy.

Being overweight has been shown not to increase mortality [qualify evidence] in older people: in a study of 70 to 75-year old Australians, mortality was lowest for "overweight" individuals (BMI 25 to 29.9), [18] while a study of Koreans found that, among those initially aged 65 or more, an increase in BMI to above 25 was not associated with ...
Researchers also did a cohort study on 19,397 babies from their birth until age seven and discovered that high-weight babies at four months were 1.38 times more likely to be overweight at seven years old compared to normal-weight babies. High-weight babies at the age of one were 1.17 times more likely to be overweight at age seven compared to ...
