摘要Objective:To examine physical activity(PA)of post-percutaneous coronary intervention(PCI)patients and explore the demographic,clinical,and social psychological characteristics associated with PA levels.Methods:A total of 246 post-PCI patients from the Peking University Third Hospital in Beijing,China,were included in this cross-sectional study through convenience sampling.Data were collected from a self-reported questionnaire.PA was categorized into low,moderate,or high levels.The ordinal multinomial logistic regression model was used to estimate the relationship among demographic,medical,and psychosocial characteristics.Results:The overall prevalence of low,moderate,and high PA was 20%,70%,and 10%,respectively.For the domain-specific PA patterns,most participants took part in leisure-time PA(84.5%);walking was the most common PA.Increased motivation and self-efficacy,lower monthly income,and unemployment were predictors of high PA.Conclusions:PA levels in post-PCI patients was not optimal,and leisure-time PA had the highest participation rate.Analyses of influencing factors can provide medical staff and health workers information to focus on high-risk groups and introduce more tailored interventions.Future studies can explore more regions,and ecological models can be introduced to study more influencing factors.
