Working age adults often work in more than one job to gain extra income or to advance skills or entrepreneurial opportunities. The objective of this study was to compare the risk of injury for those working in multiple jobs (MJH) with those working in only one job (SJH).

Using information from the National Health Interview Survey for the years 1997-2011, we estimated the rate of multiple job holding in the U.S. and compared characteristics and rates of self-reported injury (work and non-work) for SJHs vs. MJHs.

Approximately 8.4% of those employed reported working more than one job in the week before the interview. The incidence rate of work and non-work injury episodes per 100 employed workers was higher for MJHs compared with SJHs (4.2 vs. 3.3 work injuries and 9.9 vs. 7.4 non-work injuries per 100 workers, respectively). The rate ratio of injury episodes remained higher for MJHs when calculated per 100 Full time Equivalents (p<0.05).

Our findings suggest that working in multiple jobs is associated with an increased risk of an injury (work and non-work) and should be considered in injury surveillance.
