title: Cohort Profile Update: The GAZEL Cohort Study.
abstract: The original GAZEL cohort was composed of 20 625 employees of the French national gas and electricity companies (15 011 male employees then aged 40 to 50 years and 5614 women between 35 and 50 years old) at its inception in 1989. A Cohort Profile article was published in 2007. By the end of 2013, participants were aged 60-75, and almost all of them retired during follow-up. Accordingly, the main focus of research in the past decade was devoted to the study of the persistent, long-term effects of occupational exposures after retirement; of the transition between professionally active life and retirement; and on determinants of early ageing. Accordingly, in addition to the health, behavioural and social data collected yearly since the beginning of the follow-up, new data were thus collected on cognitive complaints, cognitive and physical functioning, limitations in daily activities, time use and social relationships of retirees. This update presents the main findings of research within the GAZEL Cohort Study during the past 7 years. Any research group, in France or elsewhere, can submit a research proposal to work on the GAZEL cohort. To do this, interested researchers should contact one of the principal investigators of the GAZEL Cohort Study.
