A new study offers the “strongest evidence to date” that overweight people and short people face social and economic barriers to success because of their size.
Using genetic data from more than 119,000 British people between the ages of 37 and 73, researchers from the U.S. and the U.K. found that higher body mass index is associated with lower income and greater social deprivation, which takes into account unemployment, car and home ownership, and home overcrowding.
Shorter height is associated with a lower income, level of education, and job class. The study, published in the BMJ on Wednesday, reveals that these effects are particularly punitive for shorter men and heavier women.
Several studies have previously linked tallness and thinness to higher socio-economic status in developed countries, but the direction of the association—whether being tall and thin makes people wealthy, or whether wealthy people grow tall and maintain a slim figure because they can afford better food and health care, for instance—was a mystery.
