Objective To explore the effect of different processing and drying methods of corn and hot pepper on fluorine content in coal-burning type of the endemic fluorosis areas, and to screen food processing and drying methods which meet the quality requirements of grain drying and able to effectively reduce the total fluoride intake of local population. Methods Farmers of endemic fluorosis area in Bijie, Guizhou province were divided into 3 groups: sun-baked drying group, stove drying group with air-tight cover and stove drying group with no cover, 10 households in each group. Corn and fresh hot pepper and samples dried for 2 weeks, or 1, 3, 6-month were collected, and water and fluoride content were detected, and the total daily fluoride intake were calculated in accordance with the "Determination of Water in Food" (GB/T 5009.3-2003) and "Determination of Fluorine in Foods"(GB/T 5009.18-2003). Results Fluoride content in fresh corn and dried for 2 weeks, or 1, 3, 6-month [of sunbaked drying group: (1.40 ± 0.16), (1.56 ± 0.14), (2.15 ± 0.47), (2.70 ± 0.64), (4.06 ± 1.75)mg/kg, stove drying group with air-tight cover: (1.41 ± 0.16), (2.39 ± 0.56), (4.60 ± 0.97), (8.46 ± 5.55), (11.36 ± 3.60)mg/kg,stove drying group with no cover: (1.40 ± 0.13), (4.69 ± 3.97), (4.47 ± 2.77), (9.65 ± 6.47), (26.12 ± 14.52)mg/kg] and pepper[sun-baked drying group: (5.41 ± 1.61), (16.60 ± 7.62), (32.60 ± 7.88), (50.26 ± 17.60),(240.20 ± 272.49)mg/kg, stove drying group with air-tight cover: (754 ± 2.95), (3238 ± 11.50), (119.18 ± 156.45),(224.00 ± 196.58), (495.70 ± 417.29)mg/kg, stove drying group with no cover: (4.82 ± 1.25), (44.30 ± 13.48),(122.89 ± 66.43), (334.23 ± 166.05), (531.01 ± 397.40)mg/kg] increased with elongation of drying time, and the group difference was significant(F = 44.77, 128.71, 126.87, 41.61, 53.63, 170.63, all P ＜ 0.05), with the largest rate of increase in stove drying group with no cover, and the lowest in sun-baked drying group;fluoride was significantly lower (t = 7.93,63.07,5.36,11.98,55.76,7.45, all P ＜ 0.05) after sample washing;total fluoride intake per person per day was 2.57 mg in local adult when ate washed and sun-baked corn, peppers, the total fluoride intake were 5.92, 8.14 mg when ate the food processed by other two drying methods and washed corn, peppers,respectively. Conclusions In the coal-burning type of fluorosis endemic area, should take appropriate health education measures, and instruct local residents to use sun bake their edible corn and pepper for human consumption, and cultivate a habit of washing corn and pepper before cooking, which can reduce the population total fluoride intake, and control endemic fluorosis.

Objective To evaluate the effects of implementing the health education in the Central Fund Program to control endemic fluorosis in Guizhou.Methods The samples were randomly surveyed to evaluate knowledge awareness in students and households as well as the habit formation after implementing the integrated program which mainly consisted of installing the improved stoves,supported by the Central Funds and health education in 5 counties.Results After health education,the rates of knowledge awareness in the students and the households were 94.80%(15 562/16 415)and 88.23%(4482/5080),respectively,and increased significantly compared with those before intervention[44.20%(26 364/59 645),22.81%(3082/13 510)],the difference being significant(χ2=13 324.05,6546.24,P＜0.01).The rates of drying corn and chili with the coal fire were 5.61% (57/1016)and 5.41%(55/1016),respectively,and decreased significantly compared with those before intervention [77.41%(1076/1390),78.92%(1097/1390)],the difference being significant(χ2=1214.49,1270.92,P＜0.01).The rates of washing corn and chili were 99.51%(1011/1016)and 94.59%(961/1016),respectively,and increased significantly compared with those before intervention[84.60%(1176/1390),76.55%(1064/1390)],the difference being significant(χ2=154.80,143.32,P＜0.01).The rates of using the uncovered and unventilated iron stoves and table stoves were 4.71%(38/807)and 8.37%(60/717),respectively,and decreased significantly compared with those before intervention[29.99%(14 483/48 299),98.33%(95 070/96 685)],the difierence being significant(χ2=243.51,25 282.99,P＜0.01).Conclusions Implementing the health education is the basis for the integrated measures for controlling the endemic fluorosis in the endemic regions.The consciousness and activity of the target people have been enhanced greatly.The good behaviors in the target people are forming,the expected goal is reached.

Objective To explore the influence of stoves and mode of coal-burning on the prevalence of endemic fluorosis in Guizhou Province.Methods Three previous severe endemic villages and two mild villages(as control)were investigated by ways of random sampling in the present and retrospect epidemiological study on stove usage,coal burning mode and the severity of disease.Results Before the 1990's Of 20th century all the households in the previous severe endemic villages used the open stove without ventilated pipe(chimney)and dehydrated the corn over the coal-fire of the open stoves in house,which resulted in severe pollution of the corn and indoor air by fluoride.After the 1990's,each household,although still dried the corn with the coal fire,used the table stoves and iron stoves increasingly year by year,which resulted in the decrease of the emitted fluoride from the coal fire significantly,reduced the fluoride pollution of the indoor air and the main food,thus the incidence of endemic fluorosis consequently decreased. On the other hand, most of the households in the previous severe endemic villages such as Lianhe and Yuanzi still used the open, unventilated stove without chimney, very few installed chimney leading to outside of the room,the rates being 51.3%(41/80)and 41.7%(35/84),respectively.It was concordant to the high incidence of endemic fluorosis.Compared with 1979,the detective rates of dental fluorosis in the crowd aged above 8 years old were increased significantly in Hehua Village in 2006,90.51%(248/274)and 96.08%(392/408),respectively(χ2=7.85,P＜0.01).Conclusions The usage of stoves and mode of coal-burning significantly influence the incidence of the endemic fluorosis caused by domestic coal-burningin Guizhou Province,and inappropriated use of stove and the mode of coal burning are the key factors in cause the prevalence of the severe fluorosis in endemic regions in Guizhou.
