This study aims to explore the association between a healthy lifestyle and abnormal ambulatory blood pressure (ABP) in Chinese youths.
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.
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.
A healthier lifestyle is associated with a better ambulatory BP profile among youths.
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）之间的关联。
对 1296 名大学生进行了基于学校的样本调查。通过综合 5 种生活方式因素（包括吸烟、饮酒、饮食、体育活动和睡眠）来计算生活方式评分。总分为 0 至 5 分，得分越高表示生活方式越健康。将该评分分为 3 类，代表低健康生活方式依从性（0-2 分）、中等依从性（3 分）和高依从性（4-5 分）。异常 24 小时血压（BP）定义为收缩压（SBP）≥130mmHg 和/或舒张压（DBP）≥80mmHg。异常日间 BP 定义为日间 SBP≥135mmHg 和/或 DBP≥85mmHg，而异常夜间 BP 则表现为夜间 SBP≥120mmHg 和/或 DBP≥70mmHg。我们使用二项回归模型评估了这些关联。
平均年龄为 18.81 岁，74.5%为女性。异常 24 小时 BP、日间 BP 和夜间 BP 的患病率分别为 4.2%、3.7%和 9.0%。我们发现，与低健康生活方式依从性的参与者相比，高健康生活方式依从性的参与者异常 24 小时 BP（患病率比[PR] = 0.15，95%CI：0.05，0.48）和异常日间 BP（PR = 0.16，95%CI：0.05，0.52）的患病率显著降低，且在调整了潜在混杂因素后仍然如此。
更健康的生活方式与青少年的动态血压谱更好相关。
