Correction to: Sex differences in body mass index and waist circumference trajectories and dementia risk: the HUNT4 70+ study (apr,10.1007/s11357-025-01660-3,2025)

The original version of this article unfortunately contained an error in the description of waist circumference (WC) measurement during the fourth wave of the Trøndelag Health Study (HUNT4). In page 3, under Body mass index and waist circumference section, "WC was measured at the height of the umbilicus to the nearest whole cm with the person in a standing position with arms hanging relaxed. WC was measured three times; at HUNT2, 3, and 4 (..)". However, for most participants at HUNT4, WC was measured using the InBody 770 bioimpedance body composition analyzer. The correct statement should therefore be: "WC was measured at the height of the umbilicus to the nearest whole cm with the person in a standing position with arms hanging relaxed at HUNT2 and HUNT3, and using the InBody 770 bioimpedance body composition analyzer at HUNT4. Participants who were unable to stand or had pacemakers were measured manually at HUNT4, using the same procedure as at HUNT2 and HUNT3."
