Monitoring results of coal-burning-borne endemic fluorosis in Hubei Province from 2012 to 2017 / 中华地方病学杂志

ABSTRACT

Objective@#To understand the prevention and control of coal-burning-borne endemic fluorosis in Hubei Province, and to evaluate the effects of prevention and control measures on coal-burning-borne endemic fluorosis.@*Methods@#According to the requirements of national "Coal-burning-borne Endemic Fluorosis Monitoring Program", 9 fixed monitoring villages and 15 non-fixed villages in Jianshi, Badong and Zhuxi were selected as the monitoring sites every year from 2012 to 2017, 10 households were selected in each village to carry out the dynamic monitoring of the usage of stove and health behavior related to the corn and pepper for human consumption. At the same time, the monitoring survey of children's dental fluorosis and urinary fluoride were carried out.@*Results@#From 2012 to 2017, the residents of the monitoring villages mainly used the improved stoves, the usage rates of the improved stove were all > 96%. There were statistically significant differences in the qualified rate and correct usage rate of the improved stove between each year (fixed monitoring villages χ2= 48.71, 63.72, P < 0.05; non-fixed monitoring villages χ2= 74.02, 84.80, P < 0.05). The correct usage rates of the improved stove were all 100.00% from 2015 to 2017. There were statistically significant differences in the correct rate of drying, keeping and washing eating corn and pepper between each year (fixed monitoring villages χ2= 10.18, 10.41, 4.99, 15.71, 4.67, 6.80, P < 0.05; non-fixed monitoring villages χ2= 6.22, 6.23, 18.86, 49.90, 23.88, 6.42, P < 0.05). From 2015 to 2017, all the rest rates were 100.00% except for the washing rate of pepper before eating. It showed a significant decline of dental fluorosis detection rate in 8 to 12 years old children annually (χ2=251.89, P < 0.05), from 33.57% (330/983) of 2012 to 10.26% (111/1 082) of 2017. The geometric means of urinary fluoride of children were 0.62, 0.60, 0.54, 0.53, 0.54 and 0.47 mg/L, respectively. There was statistically significant difference between each year (H=56.91, P < 0.05).@*Conclusions@#The prevention and control measures on coal-burning-borne endemic fluorosis of the 3 monitoring counties are implemented well in Hubei Province. Health behavior and life style are gradually formed, and the general condition gets better obviously.
