The objective of this study was to map and synthesize evidence on the adequacy of dietary calcium intake and dairy products in Brazilian preschoolers and schoolchildren.
Evidence searches were performed in the MEDLINE (via PubMed) and Latin American and Caribbean Health Sciences Literature (LILACS; via BVS) databases, with no restriction on date or language of publication. Experimental or observational studies that evaluated healthy Brazilian children between 2 and 12 incomplete years old were included.
A total of 18 studies were included. Seven of 11 studies of 11 studies (63.6%) identified mean values of dietary calcium intake below the age recommendation, especially in schoolchildren, with the progression of the age group. Among preschoolers, studies with direct weighing of food showed higher mean values of dietary calcium ingested compared to those with dietary recall. Children attending public daycare centers on a part-time basis tended to have inadequate calcium intake. The consumption of milk and dairy products was lower among older children, especially schoolchildren.
Inadequate dietary calcium intake seems to be prevalent in Brazil during childhood, especially among schoolchildren. Therefore, the evaluation of milk and dairy products intake must be considered in order to desgn appropriate corrective actions.
本研究旨在绘制并综合巴西学龄前儿童和学童膳食钙摄入量和乳制品摄入量充足性的证据。
在 MEDLINE（通过 PubMed）和拉丁美洲及加勒比健康科学文献数据库（LILACS；通过 BVS）中进行了证据检索，未对出版日期或语言进行限制。纳入了评估 2 至 12 岁不完全年龄段健康巴西儿童的实验或观察性研究。
共纳入 18 项研究。11 项研究中的 7 项（63.6%）发现膳食钙摄入量的平均值低于年龄推荐值，尤其是在学童中，且随着年龄组的进展而降低。在学龄前儿童中，与膳食回忆相比，直接称重食物的研究显示出更高的膳食钙摄入量平均值。在全日制日托中心接受非全日制照顾的儿童往往钙摄入量不足。随着年龄的增长，儿童对牛奶和乳制品的消费减少，尤其是学童。
在巴西，儿童期膳食钙摄入不足似乎很普遍，尤其是在学童中。因此，必须考虑评估牛奶和乳制品的摄入量，以便制定适当的纠正措施。
