Factors associated with work ability and perception of fatigue among nursing personnel from Amazonia. Rev. bras. epidemiol. [online]. 2011, vol.14, n.4, pp. 688-697.

OBJECTIVE: To analyze factors associated with inadequate work ability and perceived fatigue among nursing professionals. METHODS: A cross-sectional study was conducted involving 272 nursing personnel at an emergency hospital in Rio Branco/State of Acre, Brazil. Data collection was performed using the following instruments: questionnaire on sociodemographic data, working conditions and life styles; the Work Ability Index - WAI, and a questionnaire on perceived fatigue. Bivariate and multiple Poisson regression was used in the analysis of factors associated with work ability and perceived fatigue. RESULTS: The prevalence of inadequate work ability was 40.8% and presented the following associated factors: female sex (RP = 1.84; 95% CI 1.06 - 3.18); refering: other job commitment (RP = 1.71; 1.25 - 2.35); understaffing (RP = 1.96; 1.10 - 3.47); repetitive and monotonous tasks (RP = 1.84; 1.24 - 2.72); reporting three or more clinically undiagnosed morbidities (RP = 1.48; 1.06 - 2.06); excessive reported fatigue (RP = 2.37; 1.81 - 3.12). The prevalence of severe fatigue was 25.7% and the associated factors were: repetitive and monotonous tasks (RP = 1.74; 1.00 - 3.03); reporting three to five clinically-diagnosed morbidities (RP = 1.98; 1.00 - 3.11) and six or more self-reported morbidities (RP = 3.79; 2.04 - 7.03). CONCLUSIONS: The study revealed that most of the studied population showed reduced work ability and high levels of fatigue. These results point toward the need for interventions on an individual level (such as life conditions) and workplace improvements, looking jointly at the organizational aspects and work environment, particularly organizational aspects.
