摘要
本文通过对低海拔、中度海拔与高海拔地区人群AMD抽样调查研究,结果表明,AMD的发病随海拔增高而发病率增加(P<0.05),随年龄增加而增高,AMD在高海拔区以湿性为多,并研究了移居者与世居者发病情况,尽管二者无统计学差异,(P>0.05)但前者绝对发病率增加。作者指出,AMD在高海拔地区发病率高的主要原因可能与地面UVR增加,日照时延长有关,采取必要的紫外线(UV)防护措施,可能减少高海拔区AMD发病。此外,作者还对土著居民AMD发病相对较低的原因进行了初步探讨。
The incidence of AMD was investigated in the people who live in low-altitude area(<500m above sea-level),medial-altitude area(>2000m above sea-level)and high-altitude area(>3000m above sea level). The results show that it gets up with increased altitude and age.(P<0.005). Even though there is no statetically difference between aborigines and migrated people(P>0.05), the incidence increases absolutely in the latter. Most of AMD at high altitude area are wet type. The authors suggest that intensive UVR and long sunshine at high altitude area may play a major causitive role in AMD. The reason of low incidence in aborigines is briefly discussed in this paper.
