[Factors associated with labor capacity in electric industry workers]

The Brazilian electric utility sector has recently undergone major industrial restructuring, with impacts on working conditions and work organization that could jeopardize the capacity for work. This study aimed to evaluate factors associated with labor capacity in a sample of 475 workers from an electric utility company in the State of São Paulo, Brazil. This cross-sectional study included descriptive and multiple linear regression analyses. The mean labor capacity index (LCI) was 41.8 points (on a scale from 7.0 to 49.0). Multiple regression showed that the factors that best explained LCI variability were work stress (p < 0.001) and physical health (p < 0.001 in all the dimensions). In a separate analysis, excluding all the health dimensions, the variables associated with LCI were work stress (p < 0.001), workplace (p = 0.022), physical activity (p = 0.001), alcohol consumption (p = 0.012), and body mass index (p < 0.001). The results highlighted aspects to be considered when developing measures to protect labor capacity, with an emphasis on stress prevention and health promotion.
