Shorter people are at greater risk of developing type 2 diabetes, according to a study published Monday in the journal Diabetologia.
Researchers looked at more than 2,500 middle-aged men and women in Germany from a pool of about 26,000 people. After adjusting for age, lifestyle, education and waist circumference, researchers found that greater height was associated with a lower risk for diabetes.
The team evaluated height by taking into account both sitting height and leg length. The heights ranged from under 5'6" (169.7 cm) to above 5'11" (180.3 cm) for men and under 5'2" (157.8 cm) to above 5'6" (168.1 cm) for women.
It found that, for both men and women, the risk of diabetes was lower by more than 30% for each three inch (10 cm) difference in height.
Part of the association between greater height and a lower risk for diabetes may come from the associations between greater height and lower liver fat content and other diabetic risk factors, like blood lipids, said Matthias Schulze, an author on the study, in an email.
The study also argues that shorter people should be monitored for diabetes and risk factors related to cardiovascular disease. Because liver fat contributes so much to the higher risk in shorter individuals, reducing liver fat may provide a way to reduce the risk of diabetes.
Gail Melkus, associate dean for research in NYU's Rory Meyers College of Nursing and a diabetes researcher, called the study "a piece of the pie" in researching diabetes. Melkus is unaffiliated with the study.
"I think that the conclusions have to be cautiously interpreted because it's a secondary data analysis, meaning they didn't get a group of people and follow them going forward," she told CNN.
She said the study poses an interesting question: Should short stature be another risk factor for screening for type 2 diabetes, along with family history or obesity? More research needs to be done to determine the answer.
Still, she said short people shouldn't au
