Sjúkdómabyrð

Sjúkdómabyrð refers to the impact of a disease or health condition on a population. It encompasses both the mortality (deaths) and morbidity (illness, disability, and reduced quality of life) caused by a specific disease or group of diseases. Measuring sjúkdómabyrð is crucial for understanding the health status of a population, prioritizing public health interventions, and allocating resources effectively.

Several metrics are used to quantify sjúkdómabyrð. Life expectancy lost due to premature death and the burden of living with a disability are key components. Commonly used measures include "ár misst vegna veikinda og ótímabærs dauða" (years of life lost due to illness and premature death), often abbreviated as YLL, and "ár sem lifað er með fötlun" (years lived with disability), abbreviated as YLD. The sum of YLL and YLD gives the "ár sem lifað er með óheilsu" (disability-adjusted life years), or DALY, which represents the total burden of disease in a population.

Understanding sjúkdómabyrð helps public health officials identify the most pressing health challenges, evaluate the effectiveness of healthcare programs, and forecast future health needs. It provides a standardized way to compare the impact of different diseases and to track changes in health over time. This information is vital for developing evidence-based policies and strategies aimed at improving overall population health and well-being.
