摘要
目的探讨煤烘玉米氟病村不同摄氟量和氟负荷人群氟斑牙病情与相关经济社会因素的关系,为干预和控制煤烘玉米氟病区提供参考.方法对6个煤火烘干玉米氟病村和1个非病村总摄氟量、玉米氟和尿氟含量进行检测,用统一户表对各村约600名成年常住人口的氟斑牙、主食结构、家庭现金平均年收入等进行检查和调查.结果交通方便、现金收入高购买力强、主食玉米比例减少的氟病村,对应年龄段的氟斑牙患病率逐渐减轻,相关系数(r)为0.912和0.916(P<0.05);现金收入低的农耕氟病村各年龄段氟斑牙病情没有明显变化.玉米氟含量与学生和不同年龄段氟斑牙患病率和缺损率的r值为0.755~0.980与0.302~0.811(P值均<0.05);尿氟与学生的r值为0.811与0.915(P值均<0.05),与其余年龄段的r值无显著统计学意义.家庭现金收入与氟斑牙病情均呈负相关.结论玉米氟含量比尿氟含量与各年龄段的氟斑牙病情关系更加密切.购买力增强所带来的主食玉米比例减少,成为煤烘玉米氟病区氟斑牙病情显著减轻的主要影响因素.
Objective To discuss the relations of dental fluorosis and the social economic status in fluorosis-stricken vllages where drying the corm by buming coal was prevail.Methods A total of 6 fluorosis-endemic vllges and one non-endemic village were involved in the study.The general fhuorine intaken and the concentrations of fluorine in cormn,in the pupils'were tested.Dental fluorosis among the pupils Was also examed.A individual interview or household questionnaire survey was conducted to probe the economic condition and staple food structure in 600 adults.Results The fluorosis prevalence was lower in the villages of transportation conveniency,higher income,less coal-dried corm intake.There was a declining trend of dental fluorosis in the corresponding age groups(r:0.912,0.916;P<0.05);There was no sigificant changes in age-specified dental fluorosis in the low income villages.The correlation(r)of corm fuorine concentration and student's age-specified dental fluorosis prevalence and disparity was 0.755-0.980(P<0.05)and 0.302-0.811;The urine fluorine concentrations were 0.811 and 0.915(P<0.05).It WBS assumed that there was a negative correlation between family cash income and the dental fluorosis.Conclusions The corn fluorine concentration is closely related to age-specified dental fluorosis.With the economic improvement,taking less coal-bumed corm is the one of major factors in reducing the of dental fluoroeis in these areas.
