[The temporary work incapacities of professional administrative workers and nurses]

We show the results of a retrospective study designed to assess the features of transient job disability (TJD) episodes of workers from two groups (clerks and nurses) from an urban health basic zone with 24,536 inhabitants, out of which 6,009 were active workers registered in social security databases. Population pyramid and job distribution in active workers were obtained from a random sample including 5% of the active population, out of which 17% were clerks and 5.54% nurses. There were 1098 TJD episodes in 1990; 32.4% of them involved clerks and 8.3% nurses. The mean length of episodes was 28.2 days in nurses and 27.8 days among clerks, compared to 32.4 days in the active population. These differences remained (p < 0.001) even after excluding TJD episodes of pregnant women, in whose case the mean length of episodes involving male or female workers was the same. The percentage of TJD episodes was higher among female nurses and clerks, than among the whole female population. Influenza was responsible for 20.5% of TJD in clerks against 14.3% among nurses and 14.8% in the whole active population. We conclude that, in the groups studied, the rate of job absenteeism was higher than in the whole population, and higher in female than in males. However, in the whole population, there were no differences in TJD rates between males and females. We discuss that several factors other than illness may explain the differences among groups.
