A review of occupational physical activity and sedentary behaviour correlates.

BACKGROUND: Physical activity reduces the risk of morbidity and high sedentary time may be associated with negative health outcomes. The workplace offers an arena to promote physical activity and reduce sedentary time, but existing workplace-based interventions have typically yielded small effects. AIMS: To collate the literature on correlates of occupational physical activity and sedentary behaviour and to inform future novel approaches to workplace-based intervention or policy.
METHODS: Systematic literature searches were conducted in December 2014 using multiple databases. Identified papers were screened against an inclusion criterion. Papers were deemed eligible for this review if they included occupational physical activity and sedentary behaviour as an outcome, were quantitative observational studies and included an adult working population. Identified correlates of occupational physical activity and sedentary behaviour were organized into levels of the socioecological model.
RESULTS: Forty studies met the inclusion criterion. A higher number of studies included only occupational physical activity, not sedentary time, as an outcome and were carried out in the USA and Australia. The review identified that white-collar workers are at greater risk of low occupational physical activity and high sedentary time. The majority of correlates found to be associated with occupational physical activity and sedentary time were intrapersonal and non-modifiable.
CONCLUSIONS: Intervention efforts to increase occupational physical activity and reduce sedentary time may be most effective when targeted at white-collar workers. Research is needed to identify additional modifiable correlates of occupational physical activity and sedentary behaviour, in white-collar workers.
