This study examined trends in abdominal aortic aneurysm (AAA) incidence and mortality in New Zealand (NZ) and compared these with mortality rates from England and Wales.
Cause-specific death data were obtained from the NZ Ministry of Health, UK Office for National Statistics and National Archives (for England and Wales). The NZ National Minimum Data Set provided hospital discharge data from July 1994 to June 2009.
In 2005-2007 the age-standardized AAA mortality rate for men was 33·3 per cent less in NZ than in England and Wales (5·21 versus 7·81 per 100 000), whereas for women it was 9·8 per cent less (2·12 versus 2·35 per 100 000). Standardized mortality rates in NZ fell by 53·0 per cent for men and 34·1 per cent for women from 1991 to 2007. Between 1991-1992 and 2005-2007 the probability of a 65-year-old dying from an AAA fell by 28·2 per cent (from 1·872 to 1·344 per cent) in men, and by 6·3 per cent (from 0·837 to 0·784 per cent) in women. New AAA admission and hospital death rates in NZ peaked in 1999 for men, and in 2001 for women, and have since declined sharply. Hospital mortality ratios have also fallen, except for women with a ruptured aneurysm.
The burden of AAA disease has been falling since at least 1991 in NZ, and since 1995 in England and Wales. Although survival appears to be improving, most of the reduction is due to lower disease incidence.
本研究调查了新西兰（NZ）腹主动脉瘤（AAA）发病率和死亡率的趋势，并将其与英格兰和威尔士的死亡率进行了比较。
从新西兰卫生部、英国国家统计局和国家档案馆（英格兰和威尔士）获得了特定原因的死亡数据。新西兰国家最低数据集提供了 1994 年 7 月至 2009 年 6 月的住院数据。
2005-2007 年，新西兰男性 AAA 死亡率比英格兰和威尔士低 33.3%（5.21 比 7.81/100000），而女性低 9.8%（2.12 比 2.35/100000）。1991 年至 2007 年，新西兰男性标准化死亡率下降了 53.0%，女性下降了 34.1%。1991-1992 年至 2005-2007 年，65 岁男性死于 AAA 的概率从 1.872%降至 1.344%，下降了 28.2%；女性从 0.837%降至 0.784%，下降了 6.3%。新西兰新的 AAA 入院和住院死亡率在 1999 年达到男性峰值，在 2001 年达到女性峰值，此后急剧下降。除了破裂性动脉瘤的女性外，医院死亡率也有所下降。
自 1991 年以来，新西兰的 AAA 疾病负担一直在下降，自 1995 年以来，英格兰和威尔士的疾病负担也在下降。尽管生存情况似乎有所改善，但大部分减少是由于发病率降低。
