OBJECTIVE: This study describes the associations between sedentary behaviour (television viewing) and participation in vigorous recreational activity with @entity28 and with biomarkers of @entity65 ( @entity65 ) risk profile. DESIGN: Cross-sectional analysis of the EPIC-Norfolk cohort study. SETTING: The study is a population-based study of @entity1 living in Norfolk, UK. SUBJECTS: A total of 15 515 @entity1 and @entity1 aged between 45 and 74 y, recruited through General Practice lists, who completed the detailed physical activity questionnaire. RESULTS: Following exclusion of those with self-reported @entity583 , @entity64 and @entity6 , 14 189 @entity1 remained for the analysis. Self-reported television viewing was positively and participation in vigorous activity negatively associated with markers of @entity28 , blood pressure and plasma lipids. In multiple regression analysis, adjusting for age, alcohol, smoking, treatment for @entity101 , vigorous and total physical activity, these associations remained significant. For @entity1 who participated in more than 1 h/week of vigorous activity and who watched fewer than 2 h of television each day, the adjusted mean body mass index was 1.92 kg/m(2) less than for @entity1 who reported participating in no vigorous activity and who watched more than 4 h of television each day (P<0.001). The equivalent figure for @entity1 was 1.44 kg/m(2) (P<0.001). In a similar analysis, with blood pressure as the outcome, mean diastolic blood pressure difference between the extreme groups of vigorous activity and television viewing was 3.6 mmHg in @entity1 (P<0.001) and 2.7 mmHg (P=0.001) in @entity1 . CONCLUSIONS: These data suggest that time spent participating in vigorous recreational physical activity and television viewing, an indicator of a sedentary lifestyle, are associated with @entity28 and markers of @entity65 risk independent of total reported physical activity. Whether these observations represent the true underlying aetiological relations or are a manifestation of the different precision with which the subdimensions of activity are measured remains uncertain.

Television viewing and low participation in vigorous recreation are independently associated with @entity28 and markers of XXXX risk: EPIC-Norfolk population-based study.
