氟中毒地方病区域氟斑牙发生情况的影响因素研究

Effects of incidence of dental fluorosis endemic in fluorosis region factors

目的探讨氟中毒地方病区域氟斑牙发生情况的影响因素。方法 2014年3~7月采用多阶段分层抽样的方法抽取叙永县及古蔺县地氟病区的部分居民进行调查,并分析相关影响因素。结果氟斑牙患病率达84.95%,其中轻度902例(33.11%),中度958例(35.17%),重度454例(16.67%)。随着出生年份的增加,氟斑牙总患病率逐渐降低,差异有统计学意义(χ2=74.012,P<0.05),氟斑牙流行严重程度(CFI)也随年龄减小显著降低(F=63.912,P<0.05)。多因素Logistic回归分析结果表明影响氟斑牙患病的主要因素有12岁家里烧煤,12岁以前家里炉改灶以及年龄,家庭收入和职业。结论尽管近年来氟斑牙发生率有所下降,但2000~2003年儿童氟斑牙发病率仍然在50%左右,氟斑牙的防控工作仍需加强。影响氟斑牙发生的主要因素包括12岁家里烧煤,12岁以前家里炉改灶以及年龄,家庭收入和职业。

Objective To investigate the effects of incidence of dental fluorosis endemic in fluorosis region factors.Methods Multi-stage stratified sampling method was used to select some residents in fluorosis ill districts in Gulin,and the prevalence of dental fluorosis and the related factors were surveyed from March to July in 2014.Results The prevalence rate of dental fluorosis was 84.95%,including 902 mild cases account for 33.11%,958 moderate account for35.17%,454 cases of severe account for 16.67%.With the increase of the birth year,the prevalence rate of dental fluorosis decreased significantly(χ2=74.012,P<0.05),the severity of dental fluorosis(CFI)also decreases with age significantly decreased(F=63.912,P<0.05).Logistic analysis showed that the main influencing factors of dental fluorosis including that burn coal in home before 12 years old,reform of stove before 12 years old,age,family income and occupation.Conclusion Although the incidence of dental fluorosis decreased in recent years,but the incidence of dental fluorosis of children born from 2000 to 2003years still reached about 50%,dental fluorosis prevention and control work still needs to be strengthened.Occurrence of dental fluorosis influence factors including burn coal in home before 12 years old,reform of stove before 12 years old,age,family income and occupation.
