目的:探讨营养因素对贵州省燃煤型地方性氟中毒重病区形成的影响。方法:采用随机抽样方法,对2个重病区村寨和1个对照病区村寨作了营养因素相关流行病学现况调查。根据《中国居民膳食营养素推荐摄入量-Chinese DRIs》及《食物营养计算器V1.6》进行相关营养素计算,比较分析儿童和成人膳食营养水平。结果:2个重病区成人和儿童能量、蛋白质摄入低于国家标准和对照病区村;重病区村人群B族维生素和钙、锌、硒等元素摄入不足,尤以钙缺乏最为明显,摄入量显著低于对照病区村。结论:能量、蛋白质、维生素及钙、锌、硒等元素缺乏对地氟病重病区形成有显著影响。
Objective: To investigate the effect of nutritional factors on the formation of coal-burning endemic fluorosis in Guizhou Province. Methods: A random sampling method was used to investigate the epidemiological status of nutritional factors in two seriously ill villages and one control ward. According to “Chinese residents dietary nutrient recommended intake - Chinese DRIs” and “food nutrition calculator V1.6” related nutrients calculation, comparative analysis of children and adults dietary levels. Results: The energy and protein intake of adults and children in two seriously ill areas were lower than those of the national standard and control ward. The B vitamins, calcium, zinc, selenium and other elements of the villagers in the seriously ward were not adequately taken in, especially the calcium deficiency, The intake was significantly lower than the control ward village. Conclusion: The deficiency of energy, protein, vitamins, calcium, zinc and selenium have significant effects on the formation of endemic fluorosis.
