Scientists from University of Exeter in the UK used genetics to show that shorter height in men or higher body mass index (BMI) - a measure of weight for a given height - in women leads to reduced chances in life, including income.
Using data from 120,000 participants in the UK Biobank (aged between 40 and 70) for whom genetic information was available, researchers studied 400 genetic variants that are associated with height and 70 associated with body mass index.
The findings showed if a man was 7.5 centimetres shorter for no other reason than his genetics, this would lead him to have an income 1,500 Pounds per year less than his taller counterpart.
If a woman was a stone heavier (6.3 kilogrammes) for no other reason than her genetics, this would lead her to have an income 1,500 Pounds less per year than a comparable woman of the same height who was a stone lighter.
"Because we used genetics and 120,000 people, this is the strongest evidence to date that there's something about being shorter as a man and having a higher BMI as a woman that leads to being less well-off financially," said Jessica Tyrrell from University of Exeter.
The findings were published in the BMJ.
