摘要
目的了解试管婴儿备孕期高龄女性膳食蛋白质摄入现状。方法选取2018年9月至2019年9月在山东大学附属生殖医院拟行试管婴儿技术助孕的高龄备孕女性459例,利用食物频率法进行膳食调查,分析每日膳食蛋白质、氨基酸摄入量以及蛋白质膳食来源。结果被调查的459例备孕女性膳食蛋白质摄入量中位数为61.73 g/d,达到推荐摄入量的人群占65.14%,其中居住地来源于城镇和农村的备孕女性蛋白质摄入量中位数分别为62.76 g/d和60.35 g/d,二者间差异无统计学意义(P=0.119)。城镇备孕女性膳食蛋白质达到推荐摄入量的人群比例为70.56%,高于农村备孕女性(59.65%),差异有统计学意义(P=0.015)。459例备孕女性蛋白质食物来源以植物性食物为主,占63.08%,优质蛋白质占蛋白质供给量的33.66%;来源于谷薯类食物的蛋白质摄入量农村备孕女性高于城镇备孕女性,差异无统计学意义(P=0.070),来源于畜禽肉、鱼虾、奶类食物的蛋白质摄入量城镇备孕女性高于农村备孕女性,差异有统计学意义(P<0.05)。各种必需氨基酸评分在0.97~1.83。结论被调查的459例试管婴儿备孕期高龄女性膳食蛋白质摄入量适宜,蛋白质食物来源以植物性食物为主,必需氨基酸模式与WHO/FAO推荐模式接近;但部分人群存在蛋白质摄入不合理的情况,农村备孕女性动物蛋白摄入量有待进一步改善。
Objective To investigate the status of dietary protein intake of elderly women during in vitro fertilization(IVF).Methods A total of 459 elderly women who planned to receive IVF in the Center for Reproductive Medicine,Shandong University during Sep.2018 and Sep.2019 were selected.Their diets were surveyed using the food frequency method to calculate the daily dietary protein,amino acid intake and protein dietary sources.Results The median dietary protein intake was 61.73 g/d,and 65.14% of the subjects reached the recommended intake.The median dietary protein intake of urban and rural subjects was 62.76 g/d and 60.35 g/d,respectively,with no significant difference(P=0.019).The proportion of urban subjects who reached the recommended dietary protein intake was 70.56%,which was higher than that of rural subjects(59.65%,P=0.015).The main source of protein food was plant,accounting for 63.08%,and high-quality protein accounted for 33.66% of the protein supply.Protein from grain and potato was higher among rural subjects(P=0.070),while protein from livestock,poultry,fish,shrimp and milk was higher among urban subjects(P<0.05).The scores of essential amino acids ranged from 0.97 to 1.83.Conclusion The dietary protein intake of elderly women during IVF is appropriate.The source of protein is mainly plant food,and the essential amino acid model is close to the WHO/FAO recommended model,but some subjects have unreasonable protein intake.Rural subjects need to intake more animal protein.
