Disability free life expectancy (DFLE) is an index of mean length of healthy life. It aims at measuring the evolution in the populations state of health. The first calculations were achieved at the end of the 60s and about ten experimental calculations have been made until now, mostly in the United States, Canada, Japan and France. Nowadays this index is very well accepted. Its major qualities are its usefulness for setting health targets and determining the present and future needs. Is DFLE destined for becoming a conjonctural index of health state? The circumstances are undoubtedly propitious. Nevertheless, in order to be used in routine the DFLE index must answer three conditions, which the current approach does not fulfil i.e. the viability of disability measurement for comparisons in time; a registration of period data which is based on the incidence of entrance in disability; a calculation which is adapted to the disability whether it is reversible or not.
无残疾预期寿命（DFLE）是健康生命平均长度的一个指标。它旨在衡量人群健康状况的演变。最初的计算是在60年代末完成的，到目前为止已经进行了大约十次实验性计算，主要在美国、加拿大、日本和法国。如今，这个指标已被广泛接受。它的主要优点是对设定健康目标以及确定当前和未来需求很有用。DFLE会注定成为健康状况的一个形势指数吗？情况无疑是有利的。然而，为了在日常中使用，DFLE指标必须满足三个条件，而当前的方法并未满足，即残疾测量用于时间比较的可行性；基于残疾进入发生率的时期数据登记；一种适用于无论残疾是否可逆的计算方法。
