本文报道了1989年对大理地区地方性氟病区及非病区1558例居民的尿氟含量分析,结果表明尿氟浓度与饮水氟浓度呈正相关关系,即水氟浓度越高,尿氟浓度亦越高。病区、非病区14岁以下年龄组男女性别间尿氟浓度无显著差异,但15岁以上年龄组男性尿氟浓度高于女性。病区15岁以上年龄组尿氟浓度高于14岁以下年龄组(P<0.01),提示主要依据成人尿氟水平作为评价氟病严重程度的指标之一。本研究对大理地区尿氟正常值进行了探讨,建议以1.67毫克/升,作为大理地区尿氟正常值的上限。
This paper reports on urinary fluoride content of endemic fluorosis and non-endemic 1558 residents in Dali district in 1989. The results show that there is a positive correlation between urinary fluoride and fluoride in drinking water, that is, the higher the fluoride concentration, the greater the urinary fluoride concentration The higher. There were no significant differences in urinary fluoride concentrations between men and women in ward and non-ward age groups, but men and women aged 15 and over had higher urinary fluoride concentrations than women. Urinary fluoride concentrations in patients over 15 years old in the ward were higher than those under 14 years old (P <0.01), suggesting that urinary fluoride levels in adults were mainly used as indicators to evaluate the severity of fluorosis. This study of Dali normal urinary fluoride were discussed, it is recommended to 1.67 mg / L, as the upper limit of normal urinary fluoride in Dali.
