To provide updated estimates of life expectancy at birth for Indigenous and non-Indigenous people in the Northern Territory, 1999-2018; to quantify the contributions of changes in life years lost to disease-specific causes of death to overall changes in life expectancy.
DESIGN, SETTING, PARTICIPANTS: Analysis of Australian Coordinating Registry data on underlying and nine multiple causes of death (ICD-10) for deaths in the NT, by age, sex, and Indigenous status, 1 January 1999 - 31 December 2018.
Life expectancy at birth by year and 5-year period, by Indigenous status and sex; change in life expectancy by year and 5-year period, by Indigenous status and sex; contributions in changes in life years lost to leading underlying causes of death, by 5-year period, Indigenous status and sex.
Life expectancy for Indigenous men increased from 56.6 years in 1999 to 65.6 years in 2018 (change, 9.0 years; 95% CI, 7.9-10.0 years) and from 64.8 to 69.7 years for Indigenous women (4.9 years; 95% CI, 3.2-6.7 years); for non-Indigenous men, it increased from 77.4 to 81.0 years (3.6 years; 95% CI, 2.8-4.4 years), and from 84.3 to 85.1 years for non-Indigenous women (0.8 years; 95% CI, -0.4 to 1.9 years). Increased life expectancy for Indigenous men was primarily linked with fewer years of life lost to cancer (23% of overall change), unintentional injuries (18%), and cardiovascular disease (17%), and for Indigenous women with fewer life years lost to cancer (24%), intentional injuries (17%), and kidney disease (14%). During 1999-2018, the difference in life expectancy between Indigenous and non-Indigenous people declined by 26% for men (from 20.8 to 15.4 years) and by 21% for women (from 19.5 to 15.4 years).
Life expectancy improved markedly during 1999-2018 for Indigenous people in the NT, particularly with respect to fewer years of life lost to cancer, injuries, and chronic disease. The smaller gains in life expectancy for non-Indigenous people were linked with improved survival for those with cancer and neurological conditions.
提供北领地 1999-2018 年出生时预期寿命的最新估计值；量化因特定疾病死因而丧失的生命年变化对预期寿命总体变化的贡献。
设计、地点、参与者：对澳大利亚协调登记处关于北领地死亡的潜在和九个多种死因（ICD-10）的登记数据进行分析，按年龄、性别和土著身份进行分类，时间为 1999 年 1 月 1 日至 2018 年 12 月 31 日。
按年份和 5 年期间划分的出生时预期寿命，按土著身份和性别划分；按年份和 5 年期间划分的预期寿命变化，按土著身份和性别划分；主要潜在死因导致的生命年丧失变化的贡献，按 5 年期间、土著身份和性别进行划分。
土著男性的预期寿命从 1999 年的 56.6 岁增加到 2018 年的 65.6 岁（变化 9.0 岁；95%CI，7.9-10.0 岁），土著女性从 64.8 岁增加到 69.7 岁（4.9 岁；95%CI，3.2-6.7 岁）；对于非土著男性，从 77.4 岁增加到 81.0 岁（3.6 岁；95%CI，2.8-4.4 岁），而非土著女性从 84.3 岁增加到 85.1 岁（0.8 岁；95%CI，-0.4 岁至 1.9 岁）。土著男性预期寿命的增加主要与癌症（占总体变化的 23%）、意外伤害（18%）和心血管疾病（17%）导致的寿命损失减少有关，而土著女性则与癌症（占总体变化的 24%）、意外伤害（17%）和肾脏疾病（14%）导致的寿命损失减少有关。1999-2018 年期间，男性（从 20.8 岁降至 15.4 岁）和女性（从 19.5 岁降至 15.4 岁）的土著和非土著人之间的预期寿命差距分别缩小了 26%和 21%。
1999-2018 年期间，北领地土著居民的预期寿命显著提高，特别是癌症、伤害和慢性疾病导致的寿命损失减少。非土著人预期寿命的较小增长与癌症和神经疾病患者的生存改善有关。
