Our objective was to assess the relationship of hormones such as cortisol and dehydroepiandrosterone-sulfate (DHEA-S) with insulin resistance and overweight.
We designed and conducted a cross-sectional, observational survey consisting of home visits within a previously defined area of Mexico City. The study included 303 apparently healthy volunteers from a middle-class socioeconomic urban community. We measured glucose, cholesterol, triglycerides, insulin, cortisol, and DHEA-S. Insulin resistance (IR) was defined as belonging to the first quartile of fasting glucose/insulin ratio (G/IR) distribution or fourth quartile of IR (HOMA). Overweight was defined as body mass index (BMI) > or =25 kg/m(2).
To predict IR in women < or =35 years of age, principal component analysis (PCA) disclosed three components: 1) cholesterol, BMI, and diastolic blood pressure (DBP); 2) cholesterol, triglycerides, and cortisol, and 3) dehydroepiandrosterone-sulfate [DHEA-S]. Solely the latter (DHEA-S) was significantly associated with IR (odds ratio [OR] = 1.80, confidence interval 95% [CI 95%] 1.11-2.91, p = 0.015). For men < or =35 years of age, there were two components: 1) cholesterol, triglycerides, BMI, and DBP, and 2) DHEA-S, cholesterol, and cortisol. Component 1 was significantly associated with IR (OR = 5.65; CI 95% 1.62-19.65, p = 0.006). To predict overweight in women >35 years of age, there were three components, including 1) cholesterol and triglycerides, 2) cortisol, and 3) DHEA-S and G/IR. Component 2 was significantly associated with overweight (OR = 0.38, CI 95% 0.23-0.64, p = 0.000).
In women < or =35 years of age, high DHEA-S levels were associated with insulin resistance, which suggests that in young women DHEA-S exerts anti-estrogenic action, perhaps caused by its competitive binding with the estrogen receptor. Additionally, in women >35 years of age, low cortisol levels were associated with overweight. These associations were not identified for the male subgroup.
我们的目标是评估皮质醇和硫酸脱氢表雄酮(DHEA-S)等激素与胰岛素抵抗和超重之间的关系。
我们设计并开展了一项横断面观察性调查,包括在墨西哥城预先划定的区域内进行家访。该研究纳入了来自城市中产阶级社会经济社区的303名表面健康的志愿者。我们测量了血糖、胆固醇、甘油三酯、胰岛素、皮质醇和DHEA-S。胰岛素抵抗(IR)被定义为处于空腹血糖/胰岛素比值(G/IR)分布的第一个四分位数或胰岛素抵抗(HOMA)的第四个四分位数。超重被定义为体重指数(BMI)≥25 kg/m²。
为预测35岁及以下女性的IR,主成分分析(PCA)揭示了三个成分:1)胆固醇、BMI和舒张压(DBP);2)胆固醇、甘油三酯和皮质醇;3)硫酸脱氢表雄酮 [DHEA-S]。仅后者(DHEA-S)与IR显著相关(优势比 [OR] = 1.80,95%置信区间 [CI 95%] 1.11 - 2.91,p = 0.015)。对于35岁及以下男性,有两个成分:1)胆固醇、甘油三酯、BMI和DBP;2)DHEA-S、胆固醇和皮质醇。成分1与IR显著相关(OR = 5.65;CI 95% 1.62 - 19.65,p = 0.006)。为预测35岁以上女性的超重,有三个成分,包括1)胆固醇和甘油三酯;2)皮质醇;3)DHEA-S和G/IR。成分2与超重显著相关(OR = 0.38,CI 95% 0.23 - 0.64,p = 0.000)。
在35岁及以下女性中,高DHEA-S水平与胰岛素抵抗相关,这表明在年轻女性中DHEA-S发挥抗雌激素作用,可能是由于其与雌激素受体的竞争性结合所致。此外,在35岁以上女性中,低皮质醇水平与超重相关。在男性亚组中未发现这些关联。
