This study was designed to examine the height-for-age z-scores (HAZ), and the prevalence of intestinal inflammation, gastrointestinal infections with parasites, and enteroaggregative Escherichia coli (EAEC) in rural Panamanian children. Stool microscopy and polymerase chain reaction (PCR) testing for EAEC detected Giardia lamblia (32%, 32 of 100) and EAEC (13%, 11 of 87) in the study participants, respectively. Anthropometric analyses showed that those children who were > 12 months of age had lower HAZ scores (mean of -1.449) than the reference population. As a group, the children in the study 1 to 5 years of age did not show recovery from the previously mentioned decline in terms of their HAZ. The HAZ means of the children infected with G. lamblia, EAEC, and Ascaris lumbricoides were -1.49, -1.67, and -2.11, respectively. Furthermore, the study participants with A. lumbricoides and EAEC infections in the presence of lactoferrin showed another decrease of 0.19 and 0.13, respectively, in their HAZ means.
本研究旨在检测巴拿马农村儿童的身高年龄 Z 分数（HAZ）以及肠道炎症、寄生虫引起的胃肠道感染和肠聚集性大肠杆菌（EAEC）的流行情况。粪便显微镜检查和针对 EAEC 的聚合酶链反应（PCR）检测分别在研究参与者中检测到贾第虫属（32%，100 例中的 32 例）和 EAEC（13%，87 例中的 11 例）。人体测量分析表明，那些年龄大于 12 个月的儿童的 HAZ 评分较低（平均值为-1.449），低于参考人群。作为一个整体，1 至 5 岁的儿童在 HAZ 方面并没有从之前提到的下降中恢复过来。感染贾第虫属、EAEC 和蛔虫的儿童的 HAZ 平均值分别为-1.49、-1.67 和-2.11。此外，在乳铁蛋白存在的情况下，感染蛔虫和 EAEC 的研究参与者的 HAZ 平均值分别又下降了 0.19 和 0.13。
