In this study, the Dietary Reference Intake standards were used to evaluate the prevalence of inadequate intakes of micronutrients in obese and non-obese youth.
Dietary intake was analyzed with a dietary history taken by a registered dietitian. The obese group (n=156) had a body mass index (BMI) above the 95th percentile for age and sex. The non-obese group (n=90) was between the tenth and 85th BMI percentiles.
In the obese subjects, the prevalence of inadequate intakes was 81% for vitamin E and 27% for magnesium; the proportions with intakes below the Adequate Intakes (AIs) for calcium and vitamin D were 55% and 46%, respectively. The obese children consumed 124% of estimated need for energy, 32% of which came from fat. The non-obese had a similar prevalence of inadequate intakes (vitamin E, 93%; magnesium, 29%; calcium, 51%; vitamin D, 44%). They consumed 107% of estimated need for energy, and 31% of energy came from fat. For both groups, all other nutrient intakes were adequate.
Even though children may consume an excess of energy, they may not be meeting all of their micronutrient needs.
在本研究中，膳食参考摄入量标准被用于评估肥胖和非肥胖青少年微量营养素摄入不足的患病率。
由注册营养师采用饮食史法分析膳食摄入量。肥胖组（n = 156）的体重指数（BMI）高于年龄和性别的第95百分位数。非肥胖组（n = 90）的BMI处于第10至85百分位数之间。
在肥胖受试者中，维生素E摄入不足的患病率为81%，镁摄入不足的患病率为27%；钙和维生素D摄入量低于适宜摄入量（AI）的比例分别为55%和46%。肥胖儿童的能量摄入量为估计需求量的124%，其中32%来自脂肪。非肥胖者摄入不足的患病率相似（维生素E为93%；镁为29%；钙为51%；维生素D为44%）。他们的能量摄入量为估计需求量的107%，31%的能量来自脂肪。两组的所有其他营养素摄入量均充足。
尽管儿童可能摄入了过量的能量，但他们可能并未满足所有微量营养素的需求。
