湖南地区食用槟榔流行病学研究

目的探讨湖南地区居民咀嚼槟榔的原因和安全性,为槟榔的开发提供科学依据。方法采用多阶段抽样方法进行湖南省城乡居民咀嚼槟榔情况调查,运用国家规定的方法开展槟榔加工前后化学成分的检测及毒理学试验。结果湖南省居民咀嚼槟榔率为38.40%,其中城区为42.65%,乡村为34.12%;咀嚼槟榔的年限城区5年以下占24.72%,乡村5年以下占46.91%;日咀嚼槟榔数量的中位数城区为23.6 g,乡村为22.8 g;过瘾、提神醒脑和交际需要是居民咀嚼槟榔的前三位原因;检测17种槟榔成分,镉、锡、铅、总砷、柠檬烯、薄荷醇、香兰素加工前后无变化,加工后含量增加的有水份、脂肪和乙基麦芽酚3种,含量减少的有铁、粗纤维、锌、锰、铜、粗多糖和槟榔碱7种。毒理学实验证明,槟榔干果为无毒级,无遗传毒性和亚慢性毒作用。结论湖南地区城乡居民咀嚼槟榔已成为一种生活嗜好,食用槟榔对人体健康的影响仍有待于进一步研究。
