Calcium intake is one of the most important predictors of the amount of bone mass gained during growth. Therefore, this study was designed to estimate the dietary calcium intake of Costa Rican urban and rural adolescents ages 13-18 years old. Calcium dietary intake was determined using prospective 3-d diet records. Two-thirds (or 66.7%) or less of the Adequate Intake (AI) was used as the criterion for inadequate calcium intake as suggested by several authors. Reported mean daily calcium intake was 573 mg +/- 290. On average 82% of the adolescents did not meet two-thirds of the Al for calcium. A higher percentage of rural than urban youngsters reported inadequate calcium intake (92% and 75% respectively, p = 0.000). Likewise a higher percentage of girls (91%) than boys (77%) reported marginal calcium intake. This study shows evidence that nutritional interventions and educational strategies are urgent for increasing calcium consumption among adolescents in order to reduce the future burden of osteoporosis in old age.
钙摄入量是生长过程中获得骨量的最重要预测因素之一。因此，本研究旨在估算哥斯达黎加13 - 18岁城乡青少年的膳食钙摄入量。使用前瞻性3天饮食记录来确定膳食钙摄入量。正如几位作者所建议的，将适宜摄入量（AI）的三分之二（即66.7%）或更低作为钙摄入不足的标准。报告的平均每日钙摄入量为573毫克±290毫克。平均而言，82%的青少年未达到钙适宜摄入量的三分之二。报告钙摄入不足的农村青少年比例高于城市青少年（分别为92%和75%，p = 0.000）。同样，报告钙摄入量处于边缘水平的女孩比例（91%）高于男孩（77%）。这项研究表明，为了减轻未来老年人骨质疏松症的负担，迫切需要采取营养干预和教育策略来增加青少年的钙摄入量。
