摘要：Objectives To conduct a comprehensive analysis in Hainan centenarians on the link between sleep status and their blood pres-sure status.Furthermore,the study also aims to explore how inflammatory indicators may mediate the relationship.
Methods The China Hainan Centenarians Cohort Study(CHCCS)collected baseline data on sleep status,inflammatory indicat-ors,and blood pressure data.The study used a mediation model to investigate how inflammatory indicators mediate the relation-ship between sleep status and blood pressure status.
Result In this study,a total of 967 centenarians were included.The prevalence of hypertension among the centenarians was 71.4％.The analysis showed that centenarians with poor sleep quality had a 43％higher risk of hypertension compared to those with nor-mal sleep quality(OR=1.43,95％CI:1.03-1.97).Additionally,centenarians with nighttime sleep durations of ≤ 6 h or＞9 h had higher proportions of high pulse pressure(PP),with OR values of 1.76(95％CI:1.18-2.63)and 2.07(95％CI:1.34-3.19),respect-ively.Mediation analysis illustrated that complement C3 played a mediating role in the relationship between sleep quality and hypertension,with an effect ratio of 2.4％.Similarly,lymphocyte count,the neutrophil-to-lymphocyte ratio(NLR),and the sys-temic immune-inflammation index(SII)were identified as mediating factors in the association between nighttime sleep duration and high PP,with effect ratios of 91.22％,36.93％,and 0.20％,respectively.
Conclusion In centenarians,poor sleep quality raises the risk of hypertension,with complement C3 as a mediator.Addition-ally,nighttime sleep durations of ≤ 6 h or＞9 h increases the risk of high PP,mediated by lymphocyte count,NLR,and SII.
