Association between daily sitting time as well as vigorous activity and cardiovascular disease based on the National Health and Nutrition Examination Survey（NHANES）2007–2018: a cross-sectional study

Abstract

Objective This study aimed to examine the correlation of sitting time with cardiovascular disease (CVD) risk and to elucidate whether vigorous activity can reduce the risk of CVDs. Method A large, cross-sectional study was carried out with the National Health and Nutrition Examination Survey database 2007–2018 derived data. Meanwhile, daily sitting time, CVD history, and vigorous activity in daily life were retrieved based on 24-h recall interviews and questionnaires, whereas to investigate the correlation, subgroup and logistic regression analyses were performed. For stratifying analysis, vigorous recreational activity was employed. Results A total of 29622 participants aged ≥ 20 years who had sufficient data were enrolled in the present study. The total prevalence of CVD was 12.7%. In overall and non-vigorous recreational activity participants, the prevalence of CVD increased with the elevation of a daily sitting time (P<0.001). Nonetheless, such a trend could not be detected among patients taking vigorous recreational activity (P>0.05). Moreover, the risk of CVDs is dramatically reduced by vigorous activity (P<0.001). Conclusion According to our findings, the prevalence of CVDs increases as daily sitting time elevates in overall participants especially those not having vigorous activity. Vigorous recreational activity may balance the risk of CVDs, which is because of prolonged daily sitting time.
