Abstract

Objective: To evaluate the association between body roundness index (BRI) and stroke risk in middle-aged and elderly Chinese population.

Methods: This retrospective cohort study utilized data from the China Health and Retirement Longitudinal Study (CHARLS), including participants aged ≥45 years. BRI was the exposure variable, and stroke incidence was the outcome. Weighted Cox regression models analyzed the association and evaluated the threshold effect of BRI on stroke risk.

Results: Among 7651 participants, 519 stroke cases were identified. A one-unit increase in BRI was associated with a 15.8% elevated stroke risk [hazard ratio (HR) = 1.158, 95% confidence interval (CI): 1.158-1.159, P < 0.00001]. Quartile analysis revealed that the highest BRI quartile group had an 80.3% increased stroke risk compared to the lowest quartile (HR = 1.803, 95%CI: 1.800-1.806, P < 0.00001). A threshold effect was observed: when BRI was <5.94, a 1-unit increase was associated with an 18% increased stroke risk (HR = 1.18, 95%CI: 1.08-1.29, P = 0.0002). However, when BRI was >5.94, a 1-unit increase was associated with a non-significant 13% decreased risk (HR = 0.87, 95%CI: 0.68-1.12, P = 0.2944).

Conclusion: BRI is significantly and positively associated with stroke risk in middle-aged and elderly Chinese population, with a threshold effect observed. BRI may serve as a valuable marker for stroke prediction and prevention, particularly at lower levels. Further research is needed to investigate BRI's applicability in diverse populations and its potential in developing stroke prevention strategies. Key message What is already known on this topic.  Stroke remains a leading cause of death and disability, particularly in China, emerging body shape indices warrant investigation as cardiovascular predictors, extending beyond the cross-sectional associations documented in previous studies. What this study adds.  In this first longitudinal study of Chinese adults aged 45 and older, we identified four distinct BRI trajectory patterns over a 10-year follow-up, revealing that consistently high and rapidly increasing trajectories were associated with elevated stroke risk, with notable gender differences. How this study might affect research, practice, or policy.  Our findings support BRI trajectory monitoring as a valuable stroke risk assessment tool, emphasizing the importance of gender-specific prevention strategies, stable body shape maintenance, and early intervention for unfavorable patterns.

中国中老年人体圆度指数与脑卒中发病率的关系:CHARLS数据的纵向分析
目的:探讨中国中老年人群体圆度指数(BRI)与脑卒中风险的关系。方法:本回顾性队列研究采用中国健康与退休纵向研究(CHARLS)的数据,包括年龄≥45岁的参与者。BRI是暴露变量,卒中发生率是结果。加权Cox回归模型分析相关性,并评估BRI对卒中风险的阈值效应。结果:在7651名参与者中,确定了519例中风病例。BRI增加1个单位与卒中风险升高15.8%相关[危险比(HR) = 1.158, 95%可信区间(CI): 1.158-1.159, P 5.94, 1个单位增加与卒中风险降低13%相关(HR = 0.87, 95%CI: 0.68-1.12, P = 0.2944)。结论:BRI与中国中老年人群卒中风险显著正相关,存在阈值效应。BRI可以作为预测和预防中风的有价值的标志物,特别是在较低水平时。需要进一步研究BRI在不同人群中的适用性及其在制定卒中预防策略方面的潜力。关于这个话题的已知信息。中风仍然是导致死亡和残疾的主要原因,特别是在中国,新兴的身体形状指标值得作为心血管疾病的预测指标进行调查,超出了以往研究中记录的横断面关联。这项研究补充了什么?在这项针对45岁及以上中国成年人的首次纵向研究中,我们在10年的随访中确定了四种不同的BRI轨迹模式,揭示了持续高且快速增长的轨迹与卒中风险升高相关,且存在显著的性别差异。这项研究如何影响研究、实践或政策。我们的研究结果支持BRI轨迹监测作为一种有价值的卒中风险评估工具,强调了针对性别的预防策略、稳定的体型维持和对不利模式的早期干预的重要性。

期刊介绍: Postgraduate Medical Journal is a peer reviewed journal published on behalf of the Fellowship of Postgraduate Medicine. The journal aims to support junior doctors and their teachers and contribute to the continuing professional development of all doctors by publishing papers on a wide range of topics relevant to the practicing clinician and teacher. Papers published in PMJ include those that focus on core competencies; that describe current practice and new developments in all branches of medicine; that describe relevance and impact of translational research on clinical practice; that provide background relevant to examinations; and papers on medical education and medical education research. PMJ supports CPD by providing the opportunity for doctors to publish many types of articles including original clinical research; reviews; quality improvement reports; editorials, and correspondence on clinical matters.
