"In an earlier study, we observed that middle-aged children of long-lived siblings have lower thyroid function compared to controls from the general population,"
"In the current study, we sought to assess whether in the generation of the long-lived siblings low thyroid function was related to enhanced survival of the parents of the siblings as well,"
After rating the longevity of these siblings' parents, the team analyzed the thyroid hormones in the siblings' blood. The two sets of values appeared to be strongly linked, supporting previous findings of heritability in decreased thyroid functioning and its relationship to long life.
Is lower thyroid activity linked to longevity?
