目的了解天津市地氟病重病区的流行现状。方法根据地氟病重病区的分布特点,选取3个重病区,每个重病区按照整群抽样的方法抽取调查点,每个调查点测定水氟、8~12岁儿童氟斑牙、尿氟及对16岁~人群氟骨症患者进行临床检查和X线检查。结果在8个调查村中,儿童尿氟中位数为2.64 mg/L,女童尿氟高于男童,不同年龄儿童尿氟差异无统计学意义;水氟与尿氟之间呈高度正相关;14个调查村中儿童氟斑牙检出率为81.1%,不同性别儿童氟斑牙分度差异无统计学意义;但随年龄的增加氟斑牙分度增加,饮水氟含量与氟斑牙分度呈正相关;临床氟骨症检出率为29.2%,X线检查氟骨症阳性率为39.4%,不同性别间氟骨症差异无统计学意义,但不同年龄间氟骨症差异有统计学意义。结论天津市地氟病重病区病情依然较重,水氟越高儿童氟斑牙、成人氟骨症越严重,年龄越大成人氟骨症越严重。
Objective To understand the prevalence of endemic fluorosis in Tianjin. Methods According to the distribution of endemic fluorosis in the area, three serious wards were selected. Each serious ward was sampled according to the cluster sampling method. Fluoride, fluoride fluoride and fluoride in children aged 8 ~ 12 were measured at each investigation point. 16-year-old people with skeletal fluorosis in clinical examination and X-ray examination. Results The median urinary fluoride in children was 2.64 mg / L in 8 survey villages, urinary fluoride in girls was higher than that in boys, and urinary fluoride in children of different ages had no significant difference. There was a positive correlation between water fluoride and urinary fluoride . The detection rate of dental fluorosis among children in 14 surveyed villages was 81.1%. There was no significant difference in the dental demarcation between children of different sexes. However, with the increase of age, dental fluorosis increased, The positive rate of skeletal fluorosis was 29.2%. The positive rate of fluorosis was 39.4% by X-ray. There was no significant difference in skeletal fluorosis among different sexes, but there was statistical difference Significance of learning. Conclusion The prevalence of dendritic disease in Tianjin is still relatively high. The higher the water fluorosis, the more severe dental fluorosis in children. The older the older, the more severe the skeletal fluorosis is.
