With the addition of these important variables, specific indicators of health can be cross-tabulated to identify high-risk subpopulations of workers in your state. These include demographic information, household income, education level, health status (self-rated), life satisfaction (self-rated), asthma (ever diagnosed), cardiovascular disease (ever diagnosed), disability, body mass index, tobacco use (history and current use), alcohol consumption (# drinks per day past 30 days), exercise (outside of work, past month), sleep (days with insufficient amount, past month), seatbelt use (how often used), drinking and driving, falls, immunization (flu vaccine, past 12 months), and high-risk behavior for human immunodeficiency virus/acquired immune deficiency syndrome (past year).
This provides a new and meaningful data source that improves state-based public health surveillance systems for the prevention of work-related injury and illness, allows for better understanding of work as a social determinant of health, including health disparities related to work, and provides a potential mechanism for early identification of emerging occupational diseases. States are encouraged to administer the optional I/O module and to leverage I/O with the addition of other questions about work-related conditions, exposures, or risk factors. NIOSH provides several resources for participating states, including interviewer training and resources, coding of data received through the optional module, and dissemination of resources to partners.
