通过调查氟斑牙和氟骨症病人的生存质量 ,用加权法计算生存质量指数 ,然后根据寿命表法的原理用生存质量指数调整病区人群的期望寿命。结果饮水氟浓度为 1 0～ 2 0mg/L以下、2 0～ 4 0mg/L以下、4 0～ 7 0mg/L以下和 7 0mg/L以上的病区 ,其 0岁的质量调整期望寿命分别为 6 5 2 6 5 7、6 4 176 4、6 3 44 86和 6 3 16 2 4岁 ,即地方性氟中毒患病率越高 ,质量调整期望寿命越短。表明质量调整期望寿命作为综合衡量生存质量和生存时间的一个指标 ,可以定量地评价和比较不同国家或地区之间的健康状况和医疗水平。 By investigating the quality of life of patients with dental fluorosis and skeletal fluorosis, the quality of life index was calculated using the weighted method, and then the life expectancy index was used to adjust the life expectancy of the ward population according to the life table method. Results: 0-year-old quality adjusted life expectancy for wards with drinking water fluoride concentrations of 10 to 20 mg/L, 20 to 40 mg/L, 40 to 70 mg/L, and 70 mg/L. For 6 5 2 6 5 7, 6 4 176 4, 6 3 44 86 and 6 3 16 2 4 years old, the higher the prevalence of endemic fluorosis, the shorter the quality adjustment life expectancy. It shows that adjusting quality life expectancy as an indicator to comprehensively measure the quality of life and survival time can quantitatively evaluate and compare health status and medical level among different countries or regions.
