Predictors of Multiple Jobholding Among Dental hygienists in the State of Iowa


Little is known about the prevalence of multiple jobholding practices among dental hygienists or the factors contributing to these employment patterns. The purpose of this exploratory study was to examine predictors of multiple jobholding practices among dental hygienists in the state of Iowa.


A mailed paper survey was sent to all licensed dental hygienists (n=2080) in Iowa in May 2018. The dependent variable was whether hygienists worked more than one job in dental hygiene. Key independent variables included individual, family, and practice-related factors. Descriptive, bivariate, and binary logistic regression analyses were completed.


A total of 1215 dental hygienists participated in the survey, for a response rate of 58%. Among respondents, 12.2% worked more than one job overall, with 10.7% working 2 jobs and 1.5% working three or more. Respondents who had at least a bachelor's degree, did not have children in the household, were not married, had worked more years at their primary job, and worked more hours per week, were more likely to hold multiple jobs after adjusting for other factors.


Consistent with national estimates, there was a high multiple jobholding rate among dental hygienists in Iowa. Multiple individual, family, and practice characteristics were found to be related to multiple jobholding, with the strongest predictors being the hygienist's highest level of education and the number of hours worked at the primary job.
