In developing countries, where energy-dense foods with low nutrient content are highly accessible, the fear of feeling hungry and the desire of prolonging satiation have been documented.
To evaluate the role of valuation of eating and satiation in the relationship of food insecurity with diet, obesity, and cardiometabolic risk with structural equation modeling.
A validated questionnaire that measures the value of eating and satiation (VES) as the basis of wealth was administered to 321 adult women from Queretaro, Mexico. Instruments for measurement of socioeconomic status, food insecurity, physical activity, and a semiquantitative food frequency questionnaire were also applied. Women were measured and weighed, and they provided a fasting blood sample to determine lipid profile, glucose, and insulin concentrations. Structural equation models were used for prediction of the homeostasis model assessment-insulin resistance (HOMA-IR) index and triglyceride/high-density lipoprotein (HDL) cholesterol index.
The models confirmed, with acceptable goodness-of-fit parameters, the mediation position of VES between past experiences of food insecurity and a greater intake of carbohydrates and its impact on obesity, and on the HOMA-IR and the triglyceride/HDL-cholesterol index.
Experiences of food insecurity may increase VES in women and influence eating behavior, increasing intake of sugars and starches in their diet, thus increasing the risk of obesity and cardiometabolic diseases such as diabetes. The understanding of essential values that induce unfavorable eating behavior in a population that has experienced past food insecurity may help to develop public health strategies for prevention of cardiometabolic diseases.
在发展中国家,人们极易获取营养成分低但能量密集的食物,害怕饥饿以及渴望延长饱腹感的现象已得到证实。
运用结构方程模型评估饮食和饱腹感评估在粮食不安全与饮食、肥胖及心血管代谢风险关系中的作用。
对来自墨西哥克雷塔罗州的321名成年女性进行了一项经过验证的问卷调查,该问卷以饮食和饱腹感价值(VES)作为衡量财富的基础。还应用了社会经济地位、粮食不安全、身体活动的测量工具以及一份半定量食物频率问卷。对这些女性进行了身高和体重测量,并采集了空腹血样以测定血脂、血糖和胰岛素浓度。采用结构方程模型预测稳态模型评估-胰岛素抵抗(HOMA-IR)指数和甘油三酯/高密度脂蛋白(HDL)胆固醇指数。
模型以可接受的拟合优度参数证实了VES在过去粮食不安全经历与更多碳水化合物摄入量之间的中介地位,以及其对肥胖、HOMA-IR和甘油三酯/HDL胆固醇指数的影响。
粮食不安全经历可能会增加女性的VES并影响饮食行为,增加其饮食中糖和淀粉的摄入量,从而增加肥胖和糖尿病等心血管代谢疾病的风险。了解在过去经历过粮食不安全的人群中诱发不良饮食行为的基本价值观,可能有助于制定预防心血管代谢疾病的公共卫生策略。
