To determine if there has been a genuine fall in the incidence of acute appendicitis, an epidemiological study using HAA and Korner datasets for the years 1975-1994 was carried out to identify those children and young adults undergoing appendicectomy for acute appendicitis. The overall incidence of acute appendicitis fell from 1.84/1000 to 1.17/1000. This fall was statistically significant (R2 = 0.74, P < 0.01). The decrease was significant in both males (overall reduction, 34%) and females (overall reduction, 40%). No significant reduction was observed in either males or females between 15 and 19 years of age. The overall reduction remains essentially unexplained, but may have implications for health planning and provision of services.
为确定急性阑尾炎的发病率是否真的有所下降,开展了一项流行病学研究,利用1975年至1994年的HAA和科纳数据集,以确定那些因急性阑尾炎接受阑尾切除术的儿童和年轻人。急性阑尾炎的总体发病率从1.84/1000降至1.17/1000。这一下降具有统计学意义(R2 = 0.74,P < 0.01)。男性(总体下降34%)和女性(总体下降40%)的发病率均显著下降。15至19岁的男性和女性发病率均未观察到显著下降。总体下降的原因基本上仍不明确,但可能对卫生规划和服务提供有影响。
