长期氟暴露儿童生长发育的调查研究

目的探明长期氟暴露对儿童生长发育的影响。方法在氟中毒病区选取高氟区,并在相邻地区选择非高氟区作为对照组,分析比较两组间儿童生长发育水平的差异。结果高氟组儿童平均智商低于对照组(t=2.621,P<0.01);智商与儿童尿氟呈一定程度的负相关(r=-0.119,P<0.05)。高氟组儿童身高、体重均低于对照组(t=2.621,P<0.01;u=3.535,P<0.01)。结论长期氟暴露对儿童生长发育会产生一定的影响。针对氟暴露对儿童产生的危害,应积极采取综合防治措施,保护氟病区儿童的身体健康。

Investigation on children''''s growth and development under long -term fluoride exposure

Objective To study the influence on children's growth by long-term high fluorous exposure.Methods Case group was selected in high fluoride areas,and control group was selected in non-high fluoride areas.The difference of children's growth levels were analyzed between 2 groups.Results The IQ of case group was significantly lower than that of control group(t=2.621,P<0.01),and it was negatively correlative with the concentration of children's urinary fluoride in a certain extent(r=-0.119,P<0.05).Children's heights and weights of case group were significantly lower than that those of control group(t=2.621,P<0.01;u=3.515,P<0.01).Conclusions Long-term fluorous exposure can affect children's growth and development.In order to protect children's heath, synthetically measures of prevention and treatment should be adopted.
