BACKGROUND The aim of this study was to analyze the association between inflammatory markers and recurrent and severe falls in 1304 community-dwelling older adults from the Bambuí Cohort Study of Aging. METHODS Information about falls in the previous 12 months was collected, and classified based on recurrence (two or more falls) and severity (requirement of medical attention). The screened biomarkers included interleukins (IL-1β, IL-6, IL-10, and IL-12, TNF), chemokines (CXCL8, CXCL9, CXCL10, CCL2, and CCL5), and high-sensitive C-reactive protein (hs-PCR). Potential confounders included sociodemographic, behavioral, and health indicators. Associations were evaluated through logistic regression, using odds ratios (OR) and 95% confidence intervals (95% CI), with Stata 13.1. RESULTS The prevalence of recurrent and severe falls was 10.7% and 9.0%, respectively. After adjustments, elevated levels of IL-12 (OR: 1.92; 95% CI: 1.09-3.37) and CXCL9 (OR: 1.67; 95% CI: 1.05-2.66) were found to be associated with recurrent falls, while elevated levels of TNF (OR: 1.58; 95% CI: 1.01-2.50), IL-12 (OR: 2.04; 95% CI: 1.13-3.70), CXCL10 (OR: 1.75; 95% CI: 1.04-2.92), and CCL5 (OR: 1.90; 95% CI: 1.18-3.07) were associated with severe falls. CONCLUSIONS The results highlight a wide range of biomarkers not yet explored in the literature and suggest that inflammation may be an important component of recurrent and severe falls.

与秋天复发和严重程度相关的炎症标志物:Bambuí队列研究。

背景技术这项研究的目的是分析Bambuí队列研究中1304位社区居民中老年人的炎症标志物与反复和严重跌倒之间的关系。方法收集有关前12个月跌倒的信息,并根据复发(两次或两次以上跌倒)和严重程度(需要医疗救护)进行分类。筛选的生物标志物包括白介素(IL-1β,IL-6,IL-10和IL-12,TNF),趋化因子(CXCL8,CXCL9,CXCL10,CCL2和CCL5)和高敏感性C反应蛋白(hs -PCR)。潜在的混杂因素包括社会人口统计,行为和健康指标。通过Logistic回归使用Stata 13.1,使用比值比(OR)和95%置信区间(95%CI)对关联进行评估。结果复发和严重跌倒的患病率分别为10.7%和9.0%,分别。调整后,发现IL-12(OR:1.92; 95%CI:1.09-3.37)和CXCL9(OR:1.67; 95%CI:1.05-2.66)升高与复发性跌倒相关,而IL-12升高TNF(OR:1.58; 95%CI:1.01-2.50),IL-12(OR:2.04; 95%CI:1.13-3.70),CXCL10(OR:1.75; 95%CI:1.04-2.92)和CCL5(或:1.90; 95%CI:1.18-3.07)与严重跌倒有关。结论该结果突出了文献中尚未探索的多种生物标志物,并表明炎症可能是反复发作和严重跌倒的重要组成部分。1.75; 95%CI:1.04-2.92)和CCL5(OR:1.90; 95%CI:1.18-3.07)与严重跌倒有关。结论该结果突出了文献中尚未探讨的多种生物标志物,并提示炎症可能是反复发作和严重跌倒的重要组成部分。1.75; 95%CI:1.04-2.92)和CCL5(OR:1.90; 95%CI:1.18-3.07)与严重跌倒有关。结论该结果突出了文献中尚未探索的多种生物标志物,并表明炎症可能是反复发作和严重跌倒的重要组成部分。
