青海省班玛县大骨节病病区居民饮食结构与病情关系调查

目的探讨青海省班玛县大骨节病病区居民饮食结构与病情的关系。方法采用问卷调查方法调查居民20年饮食结构,结合1984-2004年班玛县大骨节病病情监测资料进行二者间的关系分析。结果从20世纪80年代至2004年,居民饮食构成中主食越来越少,副食逐渐增多;自产粮越来越少,外购粮逐渐增多;1984年大骨节病X线检出率(成人和儿童)为42．01％,1990年儿童大骨节病X线检出率7．50％,1998、 2004年分别降为0。结论班玛县大骨节病病情自然消退,居民病情下降可能与饮食结构改变有关。

Relationship between diet structure and Kaschin-Beck disease in Banma Couty, Qinghai Province, an endemic disease area

Objective To explore the relationship between diet structure and Kaschin-Beck disease (KBD) in Banma County, a diseased area. Methods A questionnaire regarding the residential diet structure in recent twenty years was performed, and the outcome was analyzed in combination with the data of the surveillance on KBD in the period of 1984 to 2004. Results From 1984 to 2004, cereal, rice and highland barley, which were the staple food of the local residents, made up a less and less portion in their diet structure, while non-staple food, such as meat and vegetables, was eaten in a gradually increasing portion; Local grain yeilds became less and less, which was substituted by food produced elsewhere; KBD rate examined by X-ray descended by 42.01% of 1984 to 0 of 2004. Conclusions KBD prevalence in Banma naturally fades away, the dereased morbidity may correlate with the change of the diet structure.
