[The relationship between pulmonary function and work ability of aging workers].
To explore the relationship between pulmonary function and work ability, a field study was conducted in 285 aging workers (aged 40 to 60) of different occupations in Chengdu area. The pulmonary function indices included FVC, FEV1, FEV1%, MMEF, and the pulmonary function index (PFI) which was the sum of the rating values from the first three indices. The work ability index (WAI) was also measured. Between work types, the indices, including FVC and FEV1%, showed significant difference (P < 0.05); FVC also showed significant difference between male and female workers (P < 0.05). There was a significant relationship between PFI (including FEV1% and MMEF) and WAI (P < 0.05), but the relationship between FVC (or FEV1) and WAI was not statistically significant (P > 0.05). Moreover, the agreement percentage between the classifications of PFI and WAI was 43.8%; the disagreement percentage was 4.56%. The results suggest that FEV1% and MMEF may be beneficial to the objective evaluation of the work ability of aging workers.
