Absenteeism
For absenteeism, the scores were calculated according to the following formula:[Number of hours missed from work because of health problems/(Number of hours missed from work because of health problems+Number of hours worked)]×100This resulted in a percentage of work time missed due to health ranging from 0 to 100, where 0 represents no impairment and 100 represents that the person was completely absent from work during the previous 7 days.
