Workers of CEASA: factors associated with fatigue and work ability

a cross-sectional study was conducted in 2011 and the sample was composed by 90 workers from the supply center of Campinas. Three questionnaires were used: Fatigue; Work ability index; and socio-demographic characteristics.

Results:

in the univariate regression analysis, the variables associated with work ability were: education, use of medicine, stress, pain in the last six months and pain in the last week. In univariate regression analysis the variables associated with fatigue were: education, stress, sleepiness, pain in the last six months, pain in the last week and health problems.

Conclusion:

these results indicate the need for health promotion program implementation among these workers.

Key words:
Fatigue; Work Capacity Evaluation; Life Style; Working Conditions; Nursing
