To investigate the relationship between serum ferritin levels and OSA in overweight/obese individuals and assess the association between ferritin levels and all-cause mortality in overweight/obese female OSA patients.
Cross-sectional (n = 4,809) and prospective (n = 832) data from overweight/obese adults from the 2005-2008, and 2015-March 2020 NHANES cycles were analyzed. Participants were categorized into quartiles (Q1-Q4) based on their ln-transformed serum ferritin levels. Multivariable logistic regression and restricted cubic spline regression (RCS) investigate associations. Kaplan-Meier survival analyses and Cox proportional hazards regression examined the relationship between ferritin levels and all-cause mortality in OSA patients.
After adjusting for potential confounding factors, we found that ln-transformed ferritin levels were associated with an increased risk of OSA (Q4 vs Q2: OR = 1.07, 95% CI: 1.01-1.13, P = 0.020, P for trend = 0.010). A non-linear U-shaped association was observed between ferritin levels and OSA risk (P-non-linear = 0.029), with an inflection point at ln-transformed ferritin of 4.58 (corresponding to a serum ferritin concentration of 97.51 ng/mL). In female OSA patients, elevated ferritin levels were associated with increased all-cause mortality risk (Q4 vs Q2: HR: 5.46, 95% CI: 1.18-25.16, P = 0.029, P for trend = 0.032).
Ferritin levels in overweight/obese individuals show a U-shaped relationship with OSA risk, and elevated levels correlate with increased all-cause mortality in female overweight/obese OSA patients. In the future, further research is needed to explore the potential associations between ferritin, inflammation, obesity, and OSA.
研究超重/肥胖个体血清铁蛋白水平与阻塞性睡眠呼吸暂停(OSA)之间的关系,并评估超重/肥胖女性OSA患者铁蛋白水平与全因死亡率之间的关联。
分析了2005 - 2008年以及2015年至2020年3月美国国家健康与营养检查调查(NHANES)周期中超重/肥胖成年人的横断面数据(n = 4809)和前瞻性数据(n = 832)。参与者根据其对数转换后的血清铁蛋白水平分为四分位数(Q1 - Q4)。采用多变量逻辑回归和受限立方样条回归(RCS)研究关联。采用Kaplan - Meier生存分析和Cox比例风险回归检验铁蛋白水平与OSA患者全因死亡率之间的关系。
在调整潜在混杂因素后,我们发现对数转换后的铁蛋白水平与OSA风险增加相关(Q4与Q2相比:比值比(OR)= 1.07,95%置信区间(CI):1.01 - 1.13,P = 0.020,趋势P值 = 0.010)。铁蛋白水平与OSA风险之间观察到非线性U型关联(非线性P值 = 0.029),对数转换后的铁蛋白拐点为4.58(对应血清铁蛋白浓度为97.51 ng/mL)。在女性OSA患者中,铁蛋白水平升高与全因死亡风险增加相关(Q4与Q2相比:风险比(HR):5.46,95% CI:1.18 - 25.16,P = 0.029,趋势P值 = 0.032)。
超重/肥胖个体的铁蛋白水平与OSA风险呈U型关系,且铁蛋白水平升高与超重/肥胖女性OSA患者的全因死亡率增加相关。未来需要进一步研究以探索铁蛋白、炎症、肥胖和OSA之间的潜在关联。
