Nutrient intake in aging infants and toddlers: 3-year follow-up of the Nutrintake study

We performed a 3-year follow-up of the children enrolled into the Nutrintake Study to evaluate the changes of anthropometry and nutrient intake in aging infants and toddlers. Nutrient intake was assessed using a 7-day weighted food-diary. Of the 390 Nutrintake children, 164 (42%) participated in the present study. Their median (IQR) age was 54 (48; 66) months and their anthropometrical status, expressed as standard deviation scores, remained stable during the follow-up. During the same period, there was no biologically relevant change in the intake of macronutrients expressed as percentage of energy while median increases of 757 mg/day, 0.7 mg/day and 3.1 g/1000 kcal per day were detected for sodium, iron and fibre, respectively. As compared to the Italian reference standards, the Nutrintake children continued to show at the 3-year follow-up an excessive intake of simple carbohydrates, proteins, sodium, and a low intake of iron and fibre.

我们对纳入Nutrintake研究的儿童开展了为期3年的随访，以评估生长发育中婴幼儿的人体测量学指标与营养素摄入的变化情况。营养素摄入采用7天加权食物日记法进行评估。在390名Nutrintake研究儿童中，共有164名（占比42%）参与了本项研究。受试对象的年龄中位数（四分位距，Interquartile Range, IQR）为54（48；66）月龄，以标准差评分表示的人体测量学状态在随访期间保持稳定。同期，以能量占比表征的宏量营养素摄入未出现具有生物学意义的显著变化；但钠、铁与膳食纤维的摄入中位数分别升高了757毫克/天、0.7毫克/天与3.1克/1000千卡·天。与意大利参考标准相比，Nutrintake研究儿童在3年随访结束时仍存在简单碳水化合物、蛋白质与钠摄入过量，以及铁与膳食纤维摄入不足的情况。
