DAYWORKERS AND SHIFTWORKERS LEISURE-TIME

Cross-sectional studies of working and living conditions were conducted in two Brazilian petrochemical plants between 1988-1989. This paper presents analyses of reported activities undertaken during day- and shiftworkers' leisure time. One hundred and sixteen workers (67 continuous shiftworkers) daily logged standard protocols of all leisure activities, for three consecutive weeks. Workers logged 11957 instances grouped in 27 different activities. The 14 most commonly mentioned leisure activities were analysed. Those most reported were meals with the family (breakfast, lunch, and dinner) and home TV viewing. Using chi2 statistics, the results showed that the two factors studied-activities and work schedules (day and shift)-were not related. Analysing estimated coefficients of a second order log linear model, only a very few of the 14 activities most mentioned, did not differ in their frequencies between day and shiftworkers of the same plant. The same happened with the 12 activities most-mentioned of both plants: shiftworkers and dayworkers showed significant differences (p<0.0001) on almost all frequencies of those activities mentioned. Hypotheses are made to explain some of the results. Home placement, and types of shiftwork schedules (weekly or swiftly rotating shifts) can be responsible for some of the activities performed during the workers' leisure time. Further investigation of those activities which are disturbed or cannot be performed due to work schedules is suggested.
