Abstract

Background: Physical activity (PA) and sedentary behaviour (SB) have been shown to be independent risk factors for adverse health outcomes in adults such as diabetes, obesity and chronic heart disease. Little is known however about the independent associations between worktime PA, worktime SB and absenteeism, presenteeism, body composition and musculoskeletal troubles. The aim of this study was to examine independent associations between worktime PA, worktime SB, and absenteeism, presenteeism, body composition and musculoskeletal problems in a representative population of adult workers in the North West of England. Methods: 134 sedentary workers (64.2% female, mean age 44.6 ± 9.3 years) received an ActiGraph tri-axial accelerometer to measure PA and SB. The Work Limitations Questionnaire assessed absenteeism and presenteeism, the 27-item Nordic Musculoskeletal Questionnaire assessed musculoskeletal trouble, and body mass index was the body composition marker. Results: There was a significant and positive association between worktime SB and reduced Output (OR = 1.01; 95% CI: 1.00 to 1.02, P = 0.047). Increasing worktime LPA by 10 minutes/day was significantly associated with a decrease in expected number of days off in the previous 12 months by a factor of exp(- 0.1243)=0.883 or 11.7% (P = 0.044). Increasing MVPA by 10 minutes/day was significantly associated with an increase of 12-month absenteeism by a factor of exp(0.1239)=1.132 or 13.2% (P = 0.044). No significant associations were found between worktime PA, worktime SB, and BMI or musculoskeletal troubles. Conclusions: Worktime LPA decreases the expected days absent in the last 12 months; while MVPA increases expected days absent in the last 12 months. No other significant associations were found between worktime LPA, MVPA, total PA and musculoskeletal trouble, 2-week absence, BMI or presenteeism. No significant relationships were found between worktime SB and presenteeism, absenteeism, BMI or musculoskeletal troubles. Therefore, this would suggest worktime PA rather worktime SB should be targeted in future workplace health interventions.
