鼻粘膜炎症と体質をめぐる問題—（その6）千葉県下における慢性副鼻腔炎の疫学的研究

THE RELATION OF NASAL INFLAMMATION TO CONSTITUTIONAL BACKGROTND (SIXTH REPORT) A STUDY OF CHRONIC SINUSITIS AMONG CHILDREN IN CHIBA PREFECTURE

　著者^1）はウィーンと千葉における慢性副鼻腔炎の比較で1）日本には慢性副鼻腔炎が甚だ多い。2）病因的にはウィーンにアレルギー性のものが多い。3）両者の頻度の差の原因は明らかではないが，鼻Pneumatisationに差が著しく，これがある役割をなしていることなどを明らかにした。しかしそのほか民族性，栄養，気候その他の要因も無視できないのを知り，これらの副鼻腔炎発症の意義を明らかにしようと，千葉県下各地の小学校の集団検診を行つた。

Selecting 19 different areas in Chiba Prefec turc with the school-aged children in these areas, an attempt was made to investigate the relation of the morbidity rate of sinusitis with other variable factors, such as the ind-ividual differences in the development of paranasal sinuses, the state of nutrition, the family occupation and the seasonal weather conditions.

1) The morbidity rate of sinusitis was sma- ller in the cities than on the farms; less in southern districts of the Prefecture than the northern; no definite data were obtained by difference in family occupati- ons.

2) The morbidity rate appeared to be greater among those in whom the frontal sinus was less developed.

3) No definite relation was established bet- ween the morbidity rate and other facto- rs, such as blood specific gravity, the amount of serum protein and hematocrit reading but it seemed to be occurring by far the less among those who were sup- plied with foods ample in protein, fat, calcium, iron, phosphorus, vitamin B₁ and B₂ contents than as not.

4) The morbidity rate appeared to be less in areas where the winter was mild than where it was more severe.
