Young adults' physical activity (PA) is a foundation of creating future healthy lifestyles. The purpose of this study was to explore differences in PA, sedentary behaviour, walkability and health beliefs among young adults with different levels of cardiometabolic risks and the influence of moderate-to-vigorous PA.
A cross-sectional study was conducted using a structured questionnaire.
Totally, 1149 valid responses were received for a response rate of 86.32%. According to the self-reported worst health condition, participants were categorised into healthy adults, and adults at levels 1 (overweight), 2 (obese), 3 (hypertensive, hyperlipidaemic, and/or hyperglycaemic), and 4 (with a diagnosis of cardiometabolic diseases) of cardiometabolic risks.
PA, sedentary time, walkability and health beliefs.
Significant differences in PA (=3.78, p<0.01) and sedentary time (=2.39, p<0.05) among groups with various cardiometabolic risk levels were found. Healthy adults and adults at level 1 risk had significantly higher PA than adults at risk levels 2 and 3. Young adults at risk level 3 were less likely to participate in moderate-to-vigorous PA than were healthy adults (OR=0.64 (95% CI 0.41 to 0.99), p<0.05). Individuals who perceived that there were more recreational facilities (OR=1.27 (1.05 to 1.53), p<0.05), who had higher benefits of exercise (OR=1.73 (1.30 to 2.31), p<0.001), and who had lower barriers to exercise (OR=0.42 (0.32 to 0.55), p<0.001) were more likely to participate in moderate-to-vigorous PA.
Being aware of body weight changes could be a danger sign of a lack of PA. Developing environmental and psychological strategies to promote engaging in PA is necessary to promote the cardiometabolic health of young adults.
年轻人的身体活动（PA）是创造未来健康生活方式的基础。本研究旨在探讨不同心血管代谢风险水平的年轻人在 PA、久坐行为、可步行性和健康信念方面的差异，以及中高强度 PA 的影响。
使用结构化问卷进行横断面研究。
共收到 1149 份有效回复，回复率为 86.32%。根据自我报告的最差健康状况，参与者被分为健康成年人和心血管代谢风险水平 1（超重）、2（肥胖）、3（高血压、高脂血症和/或高血糖）和 4（患有心血管代谢疾病诊断）的成年人。
PA、久坐时间、可步行性和健康信念。
发现不同心血管代谢风险水平组之间的 PA（=3.78，p<0.01）和久坐时间（=2.39，p<0.05）存在显著差异。健康成年人和风险水平 1 的成年人的 PA 明显高于风险水平 2 和 3 的成年人。风险水平 3 的年轻人参与中高强度 PA 的可能性明显低于健康成年人（OR=0.64（95%CI 0.41 至 0.99），p<0.05）。认为有更多娱乐设施（OR=1.27（1.05 至 1.53），p<0.05）、运动益处更高（OR=1.73（1.30 至 2.31），p<0.001）、运动障碍更低（OR=0.42（0.32 至 0.55），p<0.001）的个体更有可能参与中高强度 PA。
意识到体重变化可能是缺乏 PA 的危险信号。制定促进参与 PA 的环境和心理策略对于促进年轻人的心血管代谢健康是必要的。
