Scientists from Rocky Mountain Regional VA Medical Center found that whether tall or short, a person’s height increases their risk for a variety of diseases.
The research is published in PLOS Genetics and was conducted by Sridharan Raghavan et al.
Height has been a factor associated with multiple common conditions, ranging from heart disease to cancer.
But scientists have struggled to determine whether being tall or short is what puts them at risk, or if factors that affect height, like nutrition and socioeconomic status, are actually to blame.
In the study, the team set out to remove these confounding factors by looking separately at connections between various diseases and a person’s actual height, and connections to their predicted height based on their genetics.
They used data from the VA Million Veteran Program, which included genetic and health information from more than 200,000 white adults and more than 50,000 Black adults.
The results confirmed previous findings that being tall is linked to a higher risk of atrial fibrillation (a heart rhythm problem) and varicose veins, and a lower risk of coronary heart disease, high blood pressure and high cholesterol.
The study also found new associations between greater height and a higher risk of peripheral neuropathy, which is caused by damage to nerves on the extremities, as well as skin and bone infections, such as leg and foot ulcers.
The researchers conclude that height may be a previously unrecognized risk factor for several common conditions in adults.
However, they say that more studies are needed to clarify some of these associations, and that future studies would benefit from including a larger, more diverse international population.
