目的了解古蔺县地氟病区居民氟斑牙患病状况及其影响因素,为改进地氟病防治策略提供根据。方法采用多阶段分层抽样的方法抽取古蔺县地氟病区的部分居民进行调查。结果居民氟斑牙患病率为84.97%,1998年后出生的居民(8～12岁儿童)CFI为(0.84±0.86),氟斑牙患病率44.59%,1981年后出生居民的氟斑牙患病率明显降低(χ2趋势=85.08,P﹤0.001)。“12岁前家里煮饭和取暖用煤”是氟斑牙发生的主要危险因素,OR值(95%CI)为3.08(2.12～4.47)。“12岁前家中参加了改良炉灶、家庭经济年收入高”是氟斑牙发生的保护因素,OR值(95%CI)分别为0.45(0.29～0.69)、0.72(0.58～0.88)。结论该地区的地氟病防制措施取得了显著的成效,但儿童氟斑牙患病率仍然较高,应进一步分析居民降氟炉灶的使用情况及其影响因素,改进防治方案,促进地氟病防治工作的可持续发展。
Objective To understand the prevalence and influential factors of dental fluorosis among residents with endemic fluorosis in Gulin County and provide evidence for the prevention and control of fluorosis. Methods A multi-stage stratified sampling method was used to investigate some residents of the endemic fluorosis area in Gulin County. Results The prevalence of dental fluorosis in residents was 84.97%. The CFI of residents (8-12 years old) born after 1998 was (0.84 ± 0.86), the prevalence of dental fluorosis was 44.59%. The fluoride spot of residents born after 1981 The prevalence of teeth was significantly lower (χ2 trend = 85.08, P <0.001). The main risk factor for the occurrence of dental fluorosis was “cooking and heating coal at home 12 years old”, and the odds ratio (95% CI) was 3.08 (2.12 to 4.47). “At home, 12 years old participated in the improved stove, the family income is high,” is the protective factor of dental fluorosis. The odds ratio (95% CI) was 0.45 (0.29-0.69) and 0.72 (0.58-0.88) respectively. Conclusion The endemic fluorosis has achieved remarkable results in this area, but the prevalence of dental fluorosis in children is still high. The use of fluoride-lowering stoves and its influential factors should be further analyzed to improve the prevention and treatment plan and to promote fluoride Disease prevention and control work of sustainable development.
