As ofmore than 41 of these sites on the human genome have been linked to the development of obesity when a favorable environment is present. The term "non-syndromic obesity" is sometimes used to exclude these conditions.
Their ability to take advantage of rare periods of abundance by storing energy as fat would be advantageous during times of varying food availability, and individuals with greater adipose reserves would be more likely to survive famine.
This tendency to store fat, however, would be maladaptive in societies with stable food supplies. Medical illnesses that increase obesity risk include several rare genetic syndromes listed above as well as some congenital or acquired conditions: Social determinants of obesity The disease scroll Yamai no soshi, late 12th century depicts a woman moneylender with obesity, considered a disease of the rich.
While genetic influences are important to understanding obesity, they cannot explain the current dramatic increase seen within specific countries or globally. There are a number of theories as to the cause but most believe it is a combination of various factors.
The correlation between social class and BMI varies globally. A review in found that in developed countries women of a high social class were less likely to be obese. No significant differences were seen among men of different social classes.
In the developing world, women, men, and children from high social classes had greater rates of obesity. The decrease in strength of correlation was felt to be due to the effects of globalization.
A similar relationship is seen among US states: It is thought that in developed countries, the wealthy are able to afford more nutritious food, they are under greater social pressure to remain slim, and have more opportunities along with greater expectations for physical fitness.
