Metabolic Syndrome (MetS) is an energy-disturbance disease associated with insulin resistance. Hence, the intake of energy-rich macronutrients might affect some MetS components. The aim of this study was to explore the association of ingested macronutrients with MetS components in older women.
A cross sectional study was conducted in 245 older women (≥60 years). Whole-body dual-energy X-ray absorptiometry was used to assess total body fat, percentage body fat (absolute and relative), and skeletal muscle mass. Venous blood samples were collected after a 12 h fasting to determine glucose, high-density lipoprotein (HDL-c), and triglycerides. Anthropometric measurements and resting blood pressure were also evaluated. Food consumption was assessed through the 24-hour dietary recall method, and the macronutrients were distributed by tertiles of consumption. The Student t-test, Mann-Whitney U test, and logistic regression analysis were used for statistical analysis.
The MetS and non-MetS groups demonstrated similar food-energy intake and fat consumption. The MetS group presented lower protein and higher carbohydrate intake than the non-MetS group. Individuals in the lowest protein intake (<0.72 g/kg/d) had greater odds of presenting abdominal obesity and impaired glucose levels. Higher consumption of carbohydrates was associated with lower HDL levels and higher hypertriglyceridemia. The chances of having MetS were increased by three times when ingesting either a low protein or high carbohydrate diet.
Either high carbohydrate or low protein intake would be risk factors for altering MetS components and the presence of MetS in elderly women.
代谢综合征(MetS)是一种与胰岛素抵抗相关的能量失调疾病。因此,摄入富含能量的宏量营养素可能会影响某些 MetS 成分。本研究旨在探讨老年女性摄入的宏量营养素与 MetS 成分之间的关系。
对 245 名≥60 岁的老年女性进行了一项横断面研究。全身双能 X 射线吸收法用于评估全身脂肪、体脂百分比(绝对和相对)和骨骼肌量。空腹 12 小时后采集静脉血样,以测定血糖、高密度脂蛋白胆固醇(HDL-c)和甘油三酯。还评估了人体测量学测量值和静息血压。通过 24 小时膳食回忆法评估食物摄入量,并根据摄入量的三分位数分配宏量营养素。采用学生 t 检验、Mann-Whitney U 检验和逻辑回归分析进行统计学分析。
MetS 组和非 MetS 组的食物能量摄入和脂肪摄入量相似。MetS 组的蛋白质和碳水化合物摄入量低于非 MetS 组。蛋白质摄入量最低的个体(<0.72 g/kg/d)发生腹部肥胖和血糖水平受损的几率更高。碳水化合物摄入较高与 HDL 水平较低和高甘油三酯血症有关。摄入低蛋白或高碳水化合物饮食会使 MetS 的发生几率增加三倍。
高碳水化合物或低蛋白摄入均可能成为改变 MetS 成分和老年女性 MetS 发生的危险因素。
