目的了解燃煤污染型氟中毒病区改良炉灶的效果,为该防制措施提供有效依据。方法在改炉灶前、后分轻、中、重病区调查7~10岁儿童氟斑牙患病率、尿氟、居室空气氟含量并进行比较。结果改炉灶后比改炉灶前居室空气氟下降了136倍,尿氟下降了5.9倍,氟斑牙患病率由61.0%下降到21.9%。结论燃煤污染型氟中毒病区改良炉灶效果是显著的,但仍需加强改良炉灶的质量和健康教育。
Objective To understand the effect of improving stoves in coal-fired fluorosis area and provide an effective basis for the prevention measures. Methods In the light, middle and severe ward before and after the stoves were changed, the prevalence of dental fluorosis, urinary fluoride and fluoride in the air of 7-10 years old children were surveyed and compared. Results After the stove was changed, the fluoride in the air in the room was 136 times lower than that in the stove before the stove was changed, and the urinary fluoride was decreased by 5.9 times. The prevalence of dental fluorosis decreased from 61.0% to 21.9%. Conclusion The effect of improving stoves in coal-fired fluorosis area is significant, but the quality and health education of stoves should be improved.
