A prospective, longitudinal two-year study to determine the epidemiology of persistent (> or = 14 days' duration) diarrhea in rural children of Guatemala was undertaken. Three-hundred and twenty-one children aged 0-35 months were kept under surveillance by twice-a-week home visits. The overall incidence of diarrhea was 0.147 per child-week; the incidence of persistent diarrhea was 0.014 per child-week. The peak of persistent diarrhea was observed in infants below six months of age, with a continuous decline thereafter. This trend in incidence of persistent diarrhea was associated with a higher proportion (16%) of illnesses persisting for more than 13 days in children younger than six months of age as compared to children 30-35 months old (4%). Males had more diarrhea (0.156 per child-week) than females (0.139 per child week). Among children above 18 months of age, the proportion of episodes that lasted for more than 13 days was lower in females than in males.
开展了一项前瞻性纵向两年研究，以确定危地马拉农村地区儿童持续性（持续时间≥14天）腹泻的流行病学情况。对321名年龄在0至35个月的儿童进行了监测，每周进行两次家访。腹泻的总体发病率为每儿童周0.147；持续性腹泻的发病率为每儿童周0.014。持续性腹泻的高峰出现在6个月以下的婴儿中，此后持续下降。持续性腹泻发病率的这种趋势与6个月以下儿童中持续超过13天的疾病比例较高（16%）有关，而30至35个月大的儿童这一比例为4%。男性腹泻（每儿童周0.156）比女性（每儿童周0.139）更多。在18个月以上的儿童中，持续超过13天的发作比例女性低于男性。
