The dominant type of adipose tissue accumulation in the body is associated with the peculiarities of using key substrates in energy metabolism and their hormonal regulation. Hormonal and metabolic parameters were investigated in women with android and gynoid obesity before and after the short-term food deprivation test.
At baseline, at gynoid obesity as compared to android obesity, the women's blood contained lower glucose and insulin levels and higher FFA levels. The reaction to food deprivation manifested by a decrease in glucose level and an increase in FFA level in the blood is less pronounced in women with gynoid obesity than in those with android obesity. At the same time, a similar (though varying in expression) decrease in insulin level and elevated levels of glucagon, growth hormone and thyroxine were revealed in women's blood in both groups. Blood cortisol level increased in women with gynoid obesity and remained unchanged in those with android obesity.
More pronounced activation of hormonal mechanisms for maintaining blood glucose levels at gynoid obesity as compared to android one suggests that glucose is the preferable substrate for energy metabolism at gynoid obesity in women.
体内脂肪组织积累的主要类型与能量代谢中关键底物的利用特性及其激素调节有关。在短期食物剥夺试验前后,对患有腹部肥胖和臀部肥胖的女性的激素和代谢参数进行了研究。
在基线时,与腹部肥胖相比,臀部肥胖女性血液中的葡萄糖和胰岛素水平较低,游离脂肪酸(FFA)水平较高。与腹部肥胖女性相比,臀部肥胖女性血液中因食物剥夺而出现的葡萄糖水平降低和FFA水平升高的反应不那么明显。同时,两组女性血液中胰岛素水平均有类似(尽管程度不同)的下降,胰高血糖素、生长激素和甲状腺素水平升高。臀部肥胖女性的血液皮质醇水平升高,而腹部肥胖女性的则保持不变。
与腹部肥胖相比,臀部肥胖时维持血糖水平的激素机制激活更为明显,这表明葡萄糖是女性臀部肥胖时能量代谢的首选底物。
