Abstract
As the detrimental health effects of sedentary behaviour are well established, insight into the individual and environmental factors that influence adults’ sedentary behaviour is needed. Most studies to date rely on self-reported measures of sedentary time. Therefore, the aim of the current study was to examine individual and environmental correlates of objectively measured sedentary time in Dutch and Belgian adults. Between March and August 2014, Belgian (n = 133) and Dutch (n = 223) adults, recruited as sub-sample of the SPOTLIGHT survey, wore an ActiGraph accelerometer to provide objectively measured sedentary and moderate to vigorous physical activity time. Participants completed a questionnaire assessing sociodemographic (country of residence, age, gender and educational level), lifestyle (sleep, smoking, sugar-containing beverage consumption, alcohol intake), health (body mass index, self-rated health), work (employment status and type of work), happiness, physical environmental (owning a car, number of screens, socioeconomic status and residential density) and social environmental factors (social network, social cohesion). Univariate and multivariable regression analyses showed that Belgian participants had a lower odds of being sedentary for at least 9 hours per day compared to Dutch participants. Women, older participants and those meeting the WHO recommendation for physical activity were also less likely to sit for 9 hours or more per day. Participants doing (heavy) manual work or being in education, homemaker, unemployed had lower odds of being sedentary for at least 9 hours per day compared to participants with a sitting job. Those with a higher self-reported social network also had lower odds for sedentary time. No associations between physical and other social environmental characteristics and sedentary time were found. Our findings add to the growing evidence of factors associated with prolonged sedentary time in adults. These findings may be used to inform the development of strategies and interventions aimed at reducing sedentary time, and to identify high risk groups.
Highlights
Evidence has been accumulating that prolonged sedentary behaviour is associated with an elevated risk of all-cause, cancer- and cardiovascular mortality [1;2]

The objective of the current study was to explore sociodemographic, lifestyle, health, work, psychological, physical home and neighbourhood and social neighbourhood correlates of objectively measured sedentary time in adults who participated in the SPOTLIGHT (‘Sustainable prevention of obesity through integrated strategies’) project in Belgium and the Netherlands
Summary
Evidence has been accumulating that prolonged sedentary behaviour is associated with an elevated risk of all-cause, cancer- and cardiovascular mortality [1;2]. In order to combat sedentary lifestyles through approaches that target high-risk groups, information on factors that are associated with (prolonged) sedentary behaviour is essential. A review by Rhodes et al (2012) concluded that several sociodemographic factors (such as age and gender), and health and lifestyle related factors (such as physical activity (PA) and body mass index (BMI)), were linked to sedentary behaviour. They noted a lack of studies focusing on a relation with cognitive characteristics or ‘upstream’ characteristics in the social and physical environment [4]
