A study conducted in a periurban Rio de Janeiro community, Vila do João, sought to assess the extent to which diarrhea was influencing the growth of infants and young children. Using a prospective research design, the investigators studied a population of 159 children under 18 months of age living in the study area during the period January--September 1985. Weight and length measurements were used to calculate monthly weight and length increases. Information on diarrhea morbidity was collected at seven-day intervals by means of house-to-house visits. A multiple linear regression model was used to carry out the statistical analysis, which showed inverse and statistically significant correlations between the prevalence of diarrhea and increases in weight and length. It was estimated that the presence of diarrhea reduced increases in weight and length. It was estimated that the presence of diarrhea reduced increases in weight and length by averages of 13.4 g and 0.132 mm per day. These findings support the idea that control of diarrhea can improve nutritional status among children in developing countries.
在里约热内卢一个城市周边社区——若昂村开展的一项研究，旨在评估腹泻对婴幼儿生长的影响程度。采用前瞻性研究设计，研究人员对1985年1月至9月期间居住在研究区域的159名18个月以下儿童进行了研究。通过测量体重和身长来计算每月体重和身长的增长情况。每隔七天通过挨家挨户走访收集腹泻发病率信息。使用多元线性回归模型进行统计分析，结果显示腹泻患病率与体重和身长增加之间存在反向且具有统计学意义的相关性。据估计，腹泻的存在会降低体重和身长的增长。据估计，腹泻的存在使体重和身长的增长平均每天减少13.4克和0.132毫米。这些发现支持了这样一种观点，即控制腹泻可以改善发展中国家儿童的营养状况。
