The objectives of this study were to determine the head circumference (HC) values of a representative sample of 4,346 school children aged 5 to 18 years from Chile's Metropolitan Region, to carry out a comparative study with international reference data of Tanner, Nellhaus and Roche et al and to compare the HC values by socioeconomic status (SES). The sample included school children of both sexes, from public, private subsidized and private non-subsidized schools and from urban and rural areas. HC was measured according to Jelliffe norms and SES through Graffar's Modified Method. Results showed a high correlation between HC values of school-age children from Chile's Metropolitan Region and Tanner, Nellhaus and Roche et al Tables, with similar growth curves; from this manner, HC values of school-age children from Chile's Metropolitan Region not differ significantly from international reference data. HC values were, in general, significantly higher in males than females in all age groups, in students from high SES to compare with other socioeconomic strata and in older school children. This fact was tested too in 1992, in a representative sample of 605 poor school children beneficiaries from the School Feeding Program in Peñalolen and Pirque Counties from Chile's Metropolitan Region with similar results. It can be concluded that HC values of school-age children from Chile's Metropolitan Region were higher in males than females, in high SES compared with medium and low SES and in older students and does not differ significantly from international reference data.
本研究的目的是确定来自智利首都大区的4346名5至18岁学童的代表性样本的头围（HC）值，与坦纳、内尔豪斯和罗氏等人的国际参考数据进行比较研究，并按社会经济地位（SES）比较HC值。样本包括来自公立、私立补贴和私立非补贴学校以及城乡地区的男女学童。HC根据杰利夫标准进行测量，SES通过格拉法改良法进行测量。结果显示，智利首都大区学龄儿童的HC值与坦纳、内尔豪斯和罗氏等人的表格之间存在高度相关性，生长曲线相似；由此可见，智利首都大区学龄儿童的HC值与国际参考数据无显著差异。总体而言，在所有年龄组中，男性的HC值显著高于女性，高SES学生与其他社会经济阶层相比以及大龄学童的HC值也更高。1992年，在来自智利首都大区佩尼亚洛伦和皮尔克县学校供餐计划的605名贫困学童受益人的代表性样本中也进行了此项测试，结果相似。可以得出结论，智利首都大区学龄儿童的HC值男性高于女性，高SES高于中低SES，大龄学生高于小龄学生，且与国际参考数据无显著差异。
