Gene variant tied to time sitting, body mass index

By Kathryn Doyle (Reuters Health) – A common genetic variant may increase the risk of a high body mass index by increasing the amount of time a person spends sitting, according to a new study. There has been an explosion in our knowledge of the genes involved in susceptibility to obesity,” lead author Yann Klimentidis of the University of Arizona in Tucson told Reuters Health by phone. For example, he said, genes “could modulate how hungry we get or how quickly we become full after eating, modulate how active we are, and some people can sit for hours on end without any problem, some cannot sit for more than a few minutes.” “Those things probably have some genetic underlying factors,” he said.
