Excessive adipose tissue can lead to metabolic abnormalities resulting in lipid alteration and oxidative stress (OS) status. The lipid accumulation product (LAP) index is a biomarker that indicates central lipid accumulation and has been proposed as an accurate and independent indicator of risk for several cardiometabolic related conditions. There is a lack of information about the possible association of LAP and OS biomarkers. Therefore, this work aimed to investigate the relationship between LAP and OS biomarkers in adults. A cross-sectional study was performed in 250 subjects attending the Hospital Regional de Alta Especialidad de la Península de Yucatán. Anthropometrical and clinical parameters were measured. The serum oxidative biomarkers such as malondialdehyde (MDA) and total antioxidant capacity (TAC) were evaluated by spectrophotometry and by the oxygen radical absorbance capacity (ORAC), respectively. A positive and significant correlation between serum levels of MDA and LAP (r = 0.162, p = 0.010) was observed. This relationship was stronger in women (r = 0.189, p = 0.013) than in men. The association between them remained significant after adjusting for confounders (r = 0.23, p < 0.001). A cutoff of LAP of 73.73 predicts high levels of MDA in women aged between 40 and 59. LAP index was associated with OS biomarkers in women and men from Yucatan, Mexico. Therefore, the elevation of the LAP index could identify an imbalance in the redox status.
过多的脂肪组织会导致代谢异常,导致脂质改变和氧化应激(OS)状态。脂质蓄积产物(LAP)指数是一种生物标志物,表明中心脂质蓄积,并已被提出作为几种与代谢相关的心血管疾病的风险的准确和独立的指标。关于 LAP 和 OS 生物标志物之间可能的关联的信息很少。因此,这项工作旨在研究成年人中 LAP 和 OS 生物标志物之间的关系。在参加尤卡坦半岛高地专科医院的 250 名受试者中进行了一项横断面研究。测量了人体测量和临床参数。通过分光光度法和氧自由基吸收能力(ORAC)分别评估血清氧化生物标志物,如丙二醛(MDA)和总抗氧化能力(TAC)。观察到血清 MDA 水平与 LAP 之间呈正相关(r = 0.162,p = 0.010)。这种关系在女性中更强(r = 0.189,p = 0.013)。在调整混杂因素后,它们之间的关联仍然显著(r = 0.23,p < 0.001)。LAP 的截断值为 73.73 预测了 40 至 59 岁女性中 MDA 的高水平。LAP 指数与来自墨西哥尤卡坦的女性和男性的 OS 生物标志物相关。因此,LAP 指数的升高可能表明氧化还原状态失衡。
