目的为及时掌握若尔盖县饮茶型氟中毒病区居民户合格砖茶普及情况,动态评价病区人群饮茶型地氟病流行趋势,为采取针对性干预措施提供依据。方法 2011年对5个监测村50个居民户采集砖茶并测定茶氟含量,检测8～12岁儿童氟斑牙患病情况及成人氟骨症X线患病情况。结果检测村民砖茶氟含量最小值为502.05 mg/kg,最大值为1 513.4 mg/kg;平均值为990.28 mg/kg,无合格份数,日人均摄氟量达5.23 mg;检查137名8～12岁儿童,共检出极轻度及以上氟斑牙病例15例,检出率为10.95%;共X线拍摄成人氟骨症111名,检出49例氟骨症患者,检出率为44.14%。结论若尔盖县属于饮茶型氟中毒高流行区,农牧民群众处于高摄氟状态;成人氟骨症病情重,呈现慢性氟中毒蓄积。
The objective is to grasp the popularization of qualified brick-tea in households with drinking-tea-fluorosis area in Zoige County in time and to dynamically evaluate the trend of drinking tea-type endemic fluorosis in the ward, and to provide basis for taking targeted interventions. Methods In 2011, 50 brick-tea harvesters were collected from 5 monitoring villages and the content of tea fluorine was measured. The prevalence of dental fluorosis and the prevalence of X-ray of adult skeletal fluorosis in children aged 8 ~ 12 years were measured. Results The minimum fluoride content in brick tea was 502.05 mg / kg and the maximum value was 1 513.4 mg / kg in villagers. The average value was 990.28 mg / kg, In 12-year-old children, a total of 15 cases of mild and severe dental fluorosis were detected, the detection rate was 10.95%. A total of 111 adult skeletal fluorosis patients were detected by X- 44.14%. Conclusions Ruoergai County belongs to the high endemic area of drinking tea-type fluorosis. The masses of farmers and herdsmen are in a state of high fluoride exposure. Adult fluorosis patients are severely ill and present with chronic fluorosis.
