Arthritis and hypertension are the two most common health conditions affecting older workers, impacting 47% and 44%, respectively, of workers over the age of 55. An even greater proportion of workers (more than 75%) are estimated to have at least one chronic health condition that requires management. Diabetes is perhaps the most costly of these; one study found that 1/3 of all Medicare spending goes towards management of diabetes. The frequency of these conditions and others in older adults has important implications for workers can physically perform their duties, but also when. Higher morbidity means more absenteeism when an employee feels sick and more presenteeism when an employee is ill but shows up to work regardless. However, individual health risk factors are a stronger influence on future healthcare associated costs than advancing age alone. In comparing young workers with “high risk” of chronic disease (5 or more risk factors) to older workers with few or no risk factors, the younger workers had significantly higher medical costs associated despite the disparity in the age groups: 19-34 year olds, versus older workers aged 65-74.
