Quality assessment of self-inspection projects for control and evaluation of drinking water-borne endemic fluorosis in Henan Province / 中华地方病学杂志

ABSTRACT

Objective:To master the provincial-level quality assessment of the self-inspection projects for control and evaluation of drinking water-borne endemic fluorosis in the counties (cities, districts) of Henan Province, so as to ensure the quality of self-inspection.Methods:Totally 30 counties (cities, districts) with drinking water-borne endemic fluorosis in Henan Province were selected as project counties (cities, districts), using consulting and checking data, on-site investigation and review, the implementation of self-inspection projects were audited. The water improvement and the water fluorine content, and the prevalence of dental fluorosis in children aged 8-12 were investigated in villages with drinking water-borne endemic fluorosis, and the provincial-level quality assessment of the self-inspection projects was carried out.Results:A total of 99 villages with drinking water-borne endemic fluorosis in 30 counties (cities, districts) were investigated, and all 30 counties (cities, districts) completed the investigation task of self-inspection projects. A total of 99 water samples were collected, and there were 23 counties (cities, districts) with the same results of county (city, district) self-inspection and provincial-level review of water fluorine, accounting for 76.67%; a total of 5 815 children aged 8-12 were investigated, there were 18 counties (cities, districts) with the same results of county (city, district) self-inspection and provincial-level review of dental fluorosis detection rate, accounting for 60.00%.Conclusions:The self-inspection projects of control and evaluation of drinking water-borne endemic fluorosis at the county (city, district) level in Henan Province are completed well. Most of the self-inspection projects are consistent with the provincial-level review results, but the disease diagnosis ability of grass-roots professional personnel and the detection technical level of laboratory technician in some counties (cities, districts) need to be improved.
