Table 1.
Demographic characteristics of the male and female workers based on the single item self-reported work ability item.
| Variables | Male | Female | ||
|---|---|---|---|---|
| Reduced Work ability (n = 24) | Good Work ability (n = 50) | Reduced Work ability (n = 11) | Good Work ability (n = 42) | |
| Age in years (M, SD) | 37.6 (9.5) | 43.0 (9.6) | 45.6 (7.4) | 45.7 (8.2) |
| Seniority in months (M, SD) | 112.0 (114.9) | 145.3 (127.7) | 150.1 (105.6) | 146.7 (134.1) |
| BMI in kg/m2 (M, SD) | 25.4 (3.5) | 25.7 (3.2) | 26.0 (5.2) | 25.7 (6.1) |
| Current smokers (%) | 45.5 | 45.8 | 40.0 | 53.8 |
| HRR in % (M, SD) | 35.8 (6.8) | 31.0 (6.7) | 28.8 (6.1) | 31.6 (6.6) |
| Aerobic capacity in mL/kg/min (M, SD) | 34 (10) | 34 (8) | 29.1 (7) | 29 (7) |
| Influence at work (M, SD) | 33.9 (19.7) | 43.4 (19.9) | 33.0 (33.2) | 43.8 (24.1) |
Notes: Reduced work ability <8 and good work ability ≥8 on a scale from 0 (not capable of working) to 9 (best work ability); BMI = body mass index; M = mean; n = number of workers; SD = standard deviation; According to the recommendation of the STROBE statement [39], no significance test to discriminate between reduced and good work ability groups was performed.
