单不饱和式脂肪酸与腰痛和全因死亡率的关系:基于NHANES流行病学因果推论

扫码查看
背景:单不饱和式脂肪酸多被认为是对人体健康有益的一种脂肪酸,有部分研究认为其可能造成人体多部位的非炎症性疼痛.目的:探讨单不饱和式脂肪酸对腰痛发生率及全因死亡率的影响,以提供腰痛管理和预防的潜在生物标志物和干预策略.方法:采用孟德尔随机化方法结合美国NHANES数据库的大样本数据,分析单不饱和式脂肪酸对腰痛发生及全因死亡率的潜在关联.利用多种统计模型(如逆方差加权法、MR-Egger回归、简单中位数法、加权中位数法和加权中值法等)对结果进行验证和敏感性分析,以增强因果推断的可靠性.在NHANES研究中,使用多变量Cox比例风险回归模型评估不同脂肪酸比值的独立预测值,并控制混杂因素.使用Kaplan-Meier曲线、log-rank检验和限制性三次样条曲线评估单不饱和式脂肪酸与全因死亡率之间的潜在非线性关系.结果与结论:研究发现,单不饱和式脂肪酸的升高与腰痛风险的显著升高相关,表明该脂肪酸具有不利作用.同时,单不饱和式脂肪酸可能增加腰痛患者的全因死亡率.这为单不饱和式脂肪酸对腰痛及全因死亡率潜在影响提供了的新见解,并为腰痛的营养干预提供了科学依据.结果支持在欧洲人群中可以通过调整饮食结构作为预防和管理腰痛的策略之一,但需要进一步研究以探索具体的生物机制和临床应用潜力,以应用于完善中国疾病的预防和治疗的指导.
Association between monounsaturated fatty acids and low back pain and patient all-cause mortality:causal inferences based on NHANES epidemiology
BACKGROUND:Monounsaturated fatty acids are mostly recognized as a fatty acid with beneficial effects on human health,and some studies have suggested that they may contribute to non-inflammatory pain at multiple sites in the body.OBJECTIVE:To investigate the effect of monounsaturated fatty acids on the incidence of low back pain and all-cause mortality,thereby providing potential biomarkers and intervention strategies for low back pain management and prevention.METHODS:A Mendelian randomization method was used to analyze the potential association of monounsaturated fatty acids on the incidence of low back pain and all-cause mortality in conjunction with large sample data from the National Health and Nutrition Examination Survey(NHANES)database.Results were validated and sensitivity analyzed using multiple statistical models(e.g.,inverse variance weighting,MR-Egger regression,simple median,weighted median,and weighted median)to enhance the reliability of causal inferences.In the NHANES study,multivariate Cox proportional risk regression models were used to assess the independent predictive values of different fatty acid ratios and to control for confounders.Potential nonlinear relationships between monounsaturated fatty acids and all-cause mortality were assessed using Kaplan-Meier curves,log-rank tests,and restricted cubic spline curves.RESULTS AND CONCLUSION:Elevated monounsaturated fatty acids have been found to be associated with a significantly higher risk of low back pain,suggesting an unfavorable effect of this fatty acid.Also,monounsaturated fatty acids may increase all-cause mortality in patients with low back pain.This provides new insights into the potential effects of monounsaturated fatty acids on low back pain and all-cause mortality,and provides a scientific basis for nutritional interventions for low back pain.The results support the use of dietary modification as one of the strategies for the prevention and management of low back pain in the European population,but further studies are needed to explore the specific biological mechanisms and potential for clinical application,thereby improving guidance for the prevention and treatment of diseases in China.
