在常规健康信息不完整或缺乏的情况下，特别是在发展中国家，特定人群的纵向人口监测系统（DSS）可以提供重要信息。布塔吉拉农村卫生项目就是一个这样的例子，该项目于 1987 年在埃塞俄比亚农村启动。DSS 依靠定期的社区监测作为生命事件登记的一种手段，在足够的人口基础上对孕产妇死亡等相对罕见事件的发生率和趋势得出有意义的结论。然后，对特定健康问题的调查也可以使用该框架来量化特定问题或评估干预措施。根据 336000 人年的观察数据，埃塞俄比亚农村人口在 10 年间的人口特征和趋势作为 DSS 方法的说明。出生时的总体预期寿命为 50 岁。人口统计参数在 10 年间总体上显示出适度的改善趋势。DSS 方法可用于描述一段时间内社区层面的人口特征，为健康规划和干预提供重要信息。这种方法背后的方法论问题需要进一步探索和发展。
Longitudinal demographic surveillance systems (DSSs) in selected populations can provide important information in situations where routine health information is incomplete or absent, particularly in developing countries. The Butajira Rural Health Project is one such example, initiated in rural Ethiopia in 1987.DSSs rely on regular community-based surveillance as a means of vital event registration, among a sufficient population base to draw meaningful conclusions about rates and trends in relatively rare events such as maternal death. Enquiries into specific health problems can also then use this framework to quantify particular issues or evaluate interventions.Demographic characteristics and trends for a rural Ethiopian population over a 10-y period are presented as an illustration of the DSS approach, based on 336000 person-years observed. Overall life expectancy at birth was 50 y. Demographic parameters generally showed modest trends towards improvement over the 10-y period.The DSS approach is useful in characterising populations at the community level over a period of time, providing important information for health planning and intervention. Methodological issues underlying this approach need further exploration and development.
