UsualWork Profile

Related data elements about the work a person reports having performed for the longest amount of time during his or her life, regardless of the person’s current job and regardless of whether or not the person performed this work for a continuous time. Knowledge of person’s Usual Work can potentially assist in diagnosis, treatment and/or prevention of chronic condition(s) or conditions with a long latency. The potential for exposure to Occupational Hazard(s) related to an Occupation and/or an Industry can change over time, and a person could have been in and out of their Usual Work over time, so additional data are helpful to fully evaluate the possible impact of the person’s Usual Work on their health and guide appropriate use of screening tests to detect early disease. Example: a person has worked for a total of 30 years as a building carpenter (Occupation), but in various industries, mostly hotel construction. Her Usual Occupation is ‘building carpenter’ and her Usual Industry is ‘hotel construction.’ Usual Work does not include work that was unpaid or voluntary.
