This paper studied the incidence of secretory and chronic otitis among a random group of 5,950 children, aged from 4 to 9, coming from four different climatic regions of Spain, and including a group of Gypsy children. Each of the children was given a questionnaire regarding socio-economic and environmental situation and pathological antecedents; the results for sick and normal children were then statistically analysed. The most significant aetiological factors to emerge were: low economic level, prior respiratory infection, climatic conditions, cases of rhinosinusitis and acute otitis, and family history. Among Gypsy children a much greater incidence was observed, due not to racial origin but to the greater incidence of the factors cited above.
本文研究了来自西班牙四个不同气候地区、年龄在4至9岁的5950名儿童的随机样本中的分泌性中耳炎和慢性中耳炎发病率，其中包括一组吉普赛儿童。每个孩子都收到了一份关于社会经济和环境状况以及病理史的问卷；然后对患病儿童和正常儿童的结果进行了统计分析。出现的最显著病因因素有：经济水平低、既往呼吸道感染、气候条件、鼻窦炎和急性中耳炎病例以及家族病史。在吉普赛儿童中观察到的发病率要高得多，这不是由于种族原因，而是由于上述因素的发病率更高。
