Abstract:
Objective To provide a basis for specific intervention by dynamic observation of the households'related health life behavior and the children fluorosis change trend caused by the coal-burning-borne endemic fluorosis in Pu'an County.Methods Three villages were chosen using simple random sampling method in 2011-2013 for continuous monitoring.Every monitoring year in each monitoring village,according to the principle of every household survey,10 households were selected to survey related health life behavior;,and in the monitoring village all the children aged 8-12 years old were selected for Diagnosis of Dental Fluorosis (WS/T 208-2001),and in each age group,10 urine samples (half male half female) were collected,the fluoride content was determined by the ion selective electrode method (WS/T 89-1996).Results In 2011-2013,the households stoves qualified rate,stoves correct usage rate and the corn or chili correct drying rate were all 100.00％ (30/30).The dental fluorosis incidences of 8-12 years old children were 63.60％ (332/522),25.44％ (173/680) and 14.29％ (80/560),respectively,decreased year by year (x2 =324.67,P ＜ 0.05).In 2011-2013,children urinary fluoride levels were 0.83,0.84 and 0.68 mg/L,respectively.The difference between years was statistically significant (x2 =26.89,P ＜ 0.05),and the level in 2013 was significantly lower than those of 2011 and 2012 (all P ＜ 0.01).Conclusion In 2011-2013,the residents in Pu'an have good health life behavior,and the condition of children's dental fluorosis is decreased year by year.
