Longitudinal studies were done in two villages in rural Bangladesh to learn more about the interactions between infectious diseases and the nutritional status of children. An intensive system of surveillance was used to determine the occurrence and frequency of infectious diseases in a cohort of 197 children aged 2-60 months in 1978-1979. This surveillance revealed that illnesses of the upper respiratory tract, such as purulent rhinitis and pharyngitis, had the highest prevalence. Diarrheas were the second most common illnesses, with a peak prevalence rate in children 6-11 months of age. Diarrhea was also the most frequent reason for hospitalization of study children. The overall prevalence of infectious diseases was high: at least one and often several concurrent illnesses were noted on 75% of all days of observation. Compared with children in the surrounding area, children in this study had a low mortality rate, perhaps because of medical services provided during the study. Nevertheless, the extensive morbidity from infectious diseases may have had adverse effects on the growth and development of the children.
在孟加拉国农村的两个村庄开展了纵向研究，以进一步了解传染病与儿童营养状况之间的相互作用。1978 - 1979年期间，采用了一种密集监测系统来确定197名年龄在2至60个月的儿童队列中传染病的发生情况和发病频率。该监测显示，上呼吸道疾病，如脓性鼻炎和咽炎，患病率最高。腹泻是第二常见的疾病，在6至11个月大的儿童中患病率达到峰值。腹泻也是研究儿童住院的最常见原因。传染病的总体患病率很高：在所有观察日中，75%的日子里至少发现一种且常常是几种并发疾病。与周边地区的儿童相比，本研究中的儿童死亡率较低，这可能是因为研究期间提供了医疗服务。然而，传染病导致的广泛发病可能对儿童的生长发育产生了不利影响。
