ABSTRACT
Objective To evaluate the effectiveness of health education on controlling of coal-burning-borne endemic fluorosis(referred to as endemic fluorosis) in Guizhou,and to provide a scientific basis for development of control strategies.Methods A total of 37 counties were selected in Guizhou province,and 3 townships were chosen in each project county.Heath educational activities were carried out in the classes of grade 5 in the Central Primary School of each selected township.In the meantime,3 villages were chosen in each selected township where the health education for women of child-bearing age in the community was carried out.Survey on knowledge questionnaire of endemic fluorosis control was conducted among 30 students of grade 5 in the Central Primary School and 15 women of childbearing age of each selected township before and after the health educational activities.Results The knowing rate of endemic fluorosis control of pupils in all the 37 counties increased from 45.03％(14637/32505) to 89.79％(52898/58910),of women of child-bearing age increased from 38.97％ (5729/14700) to 76.55％(19198/25080) after the health education.ConclusionsThe knowing rate of endemic fluorosis control among pupils and women of child-bearing age is remarkably increased after implementing the health education projects.They have better life and health habits,and the project has reached desired goal.
ABSTRACT
Objective To study the follow-up management strategies after improving stoves for controlling coal-burning type endemic fluorosis in Guizhou and to provide a scientific basis for exploring the follow-up management measures.Methods In 2006 - 2009,three counties of Puding,Bijie and Liuzhi with improved stoves in 2005 and implemented follow-up management measures for subsequent three years were chosen,3 towns were chosen randomly in each chosen county,2 villages were selected randomly in each chosen town,10 households were investigated randomly in each chosen village,and 20 students were investigated of the knowledge of fluorosis control.The investigation included also the usage of the stoves,dehydration methods of grain and related conditions.Results ①The head of the family and student awareness of fluorosis control were 82.6％(743/900)and 91.7％ (1650/1800),respectively,and 35.0％ ( 385/1100 ) and 61.0％ (6605/10 835 ),respectively,before the test,and the difference was statistically significant( x2 =33.04,1189.12,all P ＜ 0.01 ).②The rates of chimney out of the house were 88.5％(69/78) and 100.0％(102/102),respectively,compared with those before the trial[74.4％(2125/2856) and 2.1％(104/4984),respectively],the difference was statistically significant(x2 =720.56,4295.38,all P ＜ 0.01).The iron stove and the table stove's airtight utilization rates were 85.9％(67/78) and 100.0％(102/102),respectively.③The corn and the hot pepper's correct drying rates were 100.0％(180/180).Compared with those[27.2％(49/180) and 32.2％(58/180),respectively]before the trial,the difference was statistically significant(x2 =26.68,37.38,all P ＜ 0.01 ).The corn and the hot pepper's washing rates before eating were 95.0％(57/60) and 98.3％(177/180),respectively.Compared with those[85.0％(153/180) and 77.8％(140/180)]before the trial,the difference was statistically significant(x2 =135.00,490.82,all P ＜ 0.01 ).Conclusions The target population's awareness and knowledge of fluorosis prevention and related behavior are significantly elevated and enhanced after implementation of the three years post-management,which has reached the desired goal.The strategies of the follow-up management suits Guizhou province and widespread application is suggested.
ABSTRACT
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.
