Abstract：
BACKGROUND: This study aims to explore the association between a healthy lifestyle and abnormal ambulatory blood pressure (ABP) in Chinese youths.
METHODS: A school-based sample of 1,296 college students was investigated. A lifestyle score was calculated by synthesizing 5 lifestyle factors, including smoking, alcohol consumption, diet, physical activity, and sleeping. The total score ranged from 0 to 5, with a higher score indicating a healthier lifestyle. This score was then divided into 3 categories representing low adherence to a healthy lifestyle (0-2), medium adherence (3), and high adherence (4-5). Abnormal 24-hour blood pressure (BP) was defined as systolic BP (SBP) ≥ 130 mm Hg and/or diastolic BP (DBP) ≥ 80 mm Hg. Abnormal daytime BP was determined as daytime SBP ≥ 135 mm Hg and/or DBP ≥ 85 mm Hg, while abnormal nighttime BP was characterized as nighttime SBP ≥ 120 mm Hg and/or DBP ≥ 70 mm Hg. We assessed the associations using the binomial regression model.
RESULTS: Mean age was 18.81 years, and 74.5% were women. The prevalence of abnormal 24-hour BP, daytime BP, and nighttime BP are 4.2%, 3.7%, and 9.0%, respectively. We found that participants with a high level of adherence to a healthy lifestyle had a significantly lower prevalence of abnormal 24-hour BP [prevalence ratios (PR) = 0.15, 95% CI: 0.05, 0.48] and abnormal daytime BP (PR = 0.16, 95%CI: 0.05, 0.52), when compared to those with a low level of adherence and after adjusting for the potential covariates.
CONCLUSIONS: A healthier lifestyle is associated with a better ambulatory BP profile among youths.

摘要：
背景：本研究旨在探讨中国青少年健康生活方式与异常动态血压（ABP）之间的关系。
方法：以学校为样本，对1,296名大学生进行了调查。通过综合五个生活方式因素来计算生活方式得分，包括吸烟,酒精消费,饮食，身体活动,和睡觉。总分从0到5不等，得分越高表明生活方式越健康。然后将该分数分为三类，代表对健康生活方式的低依从性（0-2），中等附着力（3），和高依从性（4-5）。24小时血压（BP）异常定义为收缩压（SBP）≥130mmHg和/或舒张压（DBP）≥80mmHg。日间血压异常确定为日间SBP≥135mmHg和/或DBP≥85mmHg，夜间血压异常表现为夜间SBP≥120mmHg和/或DBP≥70mmHg。我们使用二项回归模型评估了这些关联。
结果：平均年龄为18.81岁，74.5%为女性。24小时血压异常的患病率，白天血压，夜间血压为4.2%，3.7%,和9.0%，分别。我们发现，坚持健康生活方式的参与者24小时BP异常[患病率比（PR）=0.15，95％CI：0.05，0.48]和白天BP异常（PR=0.16，95CI：0.05，0.52）的患病率显着降低，与依从性较低的患者相比，以及在调整潜在协变量后。
结论：在年轻人中，更健康的生活方式与更好的动态血压有关。
