"This does not mean that fitness is irrelevant," says the study's last author Viktor Ahlqvist, doctoral student at the Department of Global Public Health, Karolinska Institutet. "We could still see an association, although it was weaker after taking into account factors shared by full siblings. We also think that adolescence is an important time in life for establishing good habits such as exercising and having a healthy diet."
The strength of our study, which makes it more reliable than many other conventional observational studies, is that we have used sibling analyses," says the study's first author.
