Aging, health and lifestyle as predictors of fitness for work: a new perspective for occupational physicians

We checked fit to work certifications in 2,334 workers (1,951 males and 383 females). Seven percent of male workers and 8.1% of females had limited fitness for work. The higher incidence of limitations were in workers over 55 years old in males and between 45 and 54 years old in females, in workers with a body mass index over 30 and in workers that smoke more than 20 cigarettes a day. We can conclude that aging workers have a higher rate of limitation; obesity and smoking is a prognostic factor for fitness to work limitations
