Objective measures of activity level and mortality in older men.

ABSTRACT:

Objectives

To examine associations between objective measures of activity level and mortality risk in older men.

Design

Prospective cohort study.

Setting

Six U.S. sites.

Participants

Men aged 71 and older followed an average of 4.5 years (N = 2,918).

Measurements

Time awake spent in sedentary behavior (metabolic equivalent (MET) level ≤1.50), light activity (MET level 1.51-2.99), and at least moderate activity (MET level ≥3.00) measured using an activity monitor worn for 5 days or longer and expressed as quartiles. Deaths were confirmed with death certificates; cause of death was adjudicated by review of certificates and records.

Results
