The overall burden of disease is assessed using the disability-adjusted life year (DALY), a time-based measure that combines years of life lost due to premature mortality (YLLs) and years of life lost due to time lived in states of less than full health, or years of …

The burden of disease is calculated using the disability-adjusted life year (DALY). One DALY represents the loss of the equivalent of one year of full health. DALYs for a disease or health condition are the sum of years of life lost due to premature mortality (YLLs) and years of healthy life lost due to disability (YLDs) due to prevalent cases ...

一个daly可以被看做是因为伤残而损失的一个“健康”年。 所有人的DALY加起来，可以被看作是目前人群健康状态，和无人受疾病伤残困扰、长寿的理想健康状态之间的差距，换言之就是疾病负担程度。

Disability-adjusted life years (DALYs) are a measure of overall disease burden, expressed as the number of years lost due to ill-health, disability, or early death. It was developed in the 1990s as a way of comparing the overall health and life expectancy of different countries.

失能調整生命年 （英語： disability-adjusted life year，缩写： DALY）是衡量整體 疾病負擔 的一種方法。 最初是由 世界衛生組織 所開發，現在則漸漸地在 公共衛生 和 健康影響評估 （英语：Health impact assessment） 等方面變得普遍。 失能調整生命年「擴展了因過早 死亡 而損失的潛在壽命這一概念…將因為健康狀況不佳或 失能 而損失的『健康』年歲也包括進去 [2]。 」這麼做，即可以將 死亡率 和 發病率 合併成單一的、共同的度量。

2011年12月1日 · Disability-Adjusted Life Year (DALY) The DALY is an alternative tool which emerged in the early 90s, as a means of quantifying the burden of disease. DALYs sum years of life lost (YLL) due to premature mortality and years lived in disability/disease (YLD). 1

The DALY is a summary measure which combines time lost through premature death and time lived in states of less than optimal health, loosely referred to as ^disability _. The DALY is a generalization of the well-known Potential Years of Life Lost measure (PYLLs) to include lost good health. One DALY can be : .

What is a DALY? A DALY (Disability-Adjusted Life Year) is a measure of health burden, including both reduction in life expectancy and diminished quality of life. More specifically, the DALY burden for a particular condition is the sum of YLL (years of life lost due to premature mortality) and YLD (years lost to disability).

2015年4月1日 · Disability adjusted life year (DALY) has been widely used since 1990s for evaluating global and/or regional burden of diseases. As many environmental pollutants are hazardous to human health, DALY is also recognized as an indicator to quantify the health impact of environmental pollution related to disease burden.

The disability adjusted life year (DALY) is a summary measure much like the QALY, developed by Christopher Murray and colleagues. The main difference is that it uses a scale of severity of illness from zero (full health) to unity (as bad as being dead) instead of a scale of utility from zero (dead) to unity (full health).
