Body mass index and mortality in elderly men and women: the Tromsø and HUNT studies
BACKGROUND: The impact of body mass index (BMI; kg/m(2)) and waist circumference (WC) on mortality in elderly individuals is controversial and previous research has largely focused on obesity. METHODS: With special attention to the lower BMI categories, associations between BMI and both total and ca...

METHODS: With special attention to the lower BMI categories, associations between BMI and both total and cause-specific mortality were explored in 7604 men and 9107 women aged ≥ 65 years who participated in the Tromsø Study (1994-1995) or the North-Trøndelag Health Study (1995-1997).
