Abstract:
Objective:To understand the status and tendency of coal-burning-borne endemic fluorosis after implementation of prevention and control measures in Jiangxi Province.Methods:According to the requirements of the national "Coal-burning-borne Endemic Fluorosis Monitoring Program", 3 fixed monitoring villages and 5 non-fixed monitoring villages in Luxi, Shangli were selected as monitoring sites every year from 2014 to 2018, respectively, 10 households were selected by simple random method in each village to survey the usage of stove and health behavior related to the consumption of pepper. At the same time, dental fluorosis and urinary fluoride were monitored in children aged 8 - 12 years in fixed monitoring villages.Results:There were significant differences in the utilization rate of improved stoves, the utilization rate of electric cookers and the qualified rate of improved stoves in fixed monitoring villages between each year (χ 2 = 111.70, 83.96, 36.64, P < 0.05), but there was no significant difference in the correct utilization rate of qualified improved stoves(χ 2 = 2.35, P > 0.05). There were significant differences in the utilization rate of improved stoves, the utilization rate of electric cookers, the qualified rate of improved stoves and the correct utilization rate of qualified improved stoves in non-fixed monitoring villages between each year (χ 2 = 132.32, 42.63, 50.03, 15.29, P < 0.05). There was no significant difference in pepper correct drying rates between fixed monitoring villages and non-fixed monitoring villages between each year (χ 2 = 4.068, 3.436, P > 0.05), the rate of pepper correct keeping and washing methods was 100% in monitored villages each year. From 2014 to 2018, the detection rate of dental fluorosis in children aged 8 - 12 years decreased from 17.04% (106/622) to 6.68% (90/1 347), and showed a downward trend year by year (χ 2trend = 72.60, P < 0.01). The annual geometric mean of urinary fluoride of children was 0.77, 0.74, 0.71, 0.74 and 0.72 mg/L, respectively. There was no significant difference among years ( H = 4.142, P > 0.05). Conclusion:Remarkable achievements have been made in the prevention and control of coal-burning-borne endemic fluorosis in Jiangxi Province.
