This article is from PLoS ONE, volume 9.AbstractObjective: To examine the association of constipation with exercise, non-exercise physical activity, and sedentary behaviours in Hong Kong adolescents. Methods: In 2006–2007, 42 secondary schools were randomly selected to participate in the Hong Kong Student Obesity Surveillance HKSOS project. A total of 33692 Form 1–7 students 44.9% boys; mean age 14.8, SD 1.9 years completed an anonymous questionnaire on lifestyle behaviours. Constipation was defined as a frequency of evacuation of less than once every two days. Exercise moderate-to-vigorous levels and non-exercise physical activity NEPA were each considered insufficient when less than 1 hour per day, and sedentary behaviours were considered excessive when over 4 hours per day. Logistic regression was used to calculate adjusted odds ratio AOR for constipation in relation to exercise, NEPA, and sedentary behaviours, adjusting for potential confounders. Results: Constipation was identified in 15.6% 95% CI 15.2% – 16.0% of adolescents overall, 14.0% in those with sufficient exercise and 19.6% in those without. Constipation was associated with insufficient exercise AOR 1.26, 95% CI 1.16 – 1.36, insufficient NEPA 1.21 1.10 – 1.33 and excessive sedentary behaviours 1.25, 1.17 – 1.34. Compared with having none of the above 3 inactive behaviours, increasing AORs of constipation were observed for having 1 AOR 1.23, 2 AOR 1.57 and 3 AOR 1.88 inactive behaviours p for trend
