Abstract

Objective To explore the differences of physical activity levels between Chinese and British patients with cardiovascular disease (CVD) and its influencing factors. Methods Based on the baseline survey of China Kadoorie Biobank (CKB) and United Kingdom Biobank (UKB), we identified the case and control group according to the self-reported disease history in the questionnaire. Metabolic equivalent of task, as the assessment of physical activity level, was graded according to the tertiles of specific ages and genders. Multiple logistic regression models were used to analyze the correlation between CVD status and physical activity levels. Results We included 509 170 Chinese adults and 360 360 British adults in the analysis. After adjusting for multiple factors, we found a positive correlation between CVD patients and low physical activity levels in both CKB and UKB populations (CKB: OR =1.21, 95% CI :1.17-1.25; UKB: OR =1.24, 95% CI :1.20-1.28). There was a high correlation between the prevalence of CVD and low physical activity levels in males with CKB ( OR =1.33, 95% CI :1.27-1.40).Unlike the UKB population, as the length of CVD increased, the physical activity levels of CKB patients gradually approached that of the non-CVD population, and stroke was positively correlated with low physical activity levels ( OR =1.46, 95% CI :1.38-1.53). The decline in physical activity was more pronounced among CKB and UKB CVD patients with lower educational levels, current or former smokers or drinkers, and those with other chronic diseases. In CKB, there showed a high correlation between CVD disease and low physical activity levels in rural areas and non-retired populations. In UKB, there appeared a higher correlation between CVD disease and low physical activity levels in urban and non-working populations. Conclusions The physical activity levels of CVD patients in both China and the UK were lower than that in non-CVD population. In addition to low-educated individuals, current or former smokers or drinkers, and those with other chronic diseases, it is critical to pay attention to the physical activity levels of rural, male, and non-retirees among Chinese patients.</p>
