Descriptive and transversal study, first to report the dietary intake of energy and macronutrients in pregnant women in the northeast of Mexico. Convenience sample of 125 pregnant women (15-45 years of age) in the third trimester, who were prenatal patients in the Hospital Regional Materno Infantil, Nuevo León, Mexico. It was reported the level of studies, marital and professional status, weight, height and body mass index (BMI). Diet was evaluated by 24-hour food recalls, in 3 non-consecutive days. There were analyzed the intake of energy and the percentage contribution of calories from macronutrients according to the recommendations of intake of pregnant women. Intake of energy was 1683,8 Cal/day. The caloric contribution of saturated fat was higher than the recommendation in 53.6% of women. 76.8% of participants ate more than 55% of energy from carbohydrates, while 86.4% ate more sugars than the amount suggested. The median intake of protein was 12.0% of total energy intake. 75% of participants consumed less than 22,5 g of total dietary fiber. The relevance of knowing the intakes of energy and macronutrients in pregnant women may be due to the possible influence of diet over the child's appetite and maternal complications. Results of this study suggest the need to provide women with adequate nutritional recommendations since the first trimester of gestation, according to their nutritional status and social environment.
描述性横断面研究,首次报告墨西哥东北部孕妇的能量和常量营养素膳食摄入量。选取了125名孕晚期孕妇(年龄15 - 45岁)作为便利样本,她们均为墨西哥新莱昂州地区母婴医院的产前患者。报告了她们的学历水平、婚姻和职业状况、体重、身高以及体重指数(BMI)。通过连续3天的24小时食物回顾法评估饮食情况。根据孕妇的摄入量建议,分析了能量摄入量以及常量营养素热量的百分比贡献。能量摄入量为1683.8千卡/天。53.6%的女性饱和脂肪的热量贡献高于建议值。76.8%的参与者碳水化合物提供的能量超过55%,而86.4%的人摄入的糖超过建议量。蛋白质摄入量中位数占总能量摄入量的12.0%。75%的参与者膳食纤维总摄入量低于22.5克。了解孕妇能量和常量营养素摄入量的相关性可能是由于饮食对胎儿食欲和母体并发症可能产生的影响。本研究结果表明,有必要根据孕妇的营养状况和社会环境,从妊娠早期就为其提供适当的营养建议。
