Conversely, premature death can refer to a death that occurs before old age arrives, for example, human death before a person reaches the age of 75. [76] Animal and plant cells normally reproduce and function during the whole period of natural existence, but the aging process derives from the deterioration of cellular activity and the ruination ...
Years of potential life lost (YPLL) or potential years of life lost (PYLL) is an estimate of the average years a person would have lived if they had not died prematurely. [1] It is, therefore, a measure of premature mortality. As an alternative to death rates, it is a method that gives more weight to deaths that occur among younger people.
1 in 1,000–10,000. Sudden infant death syndrome (SIDS), sometimes known as cot death, is the sudden unexplained death of a child of less than one year of age.

63,250–70,000. 70,000–80,000. More than 80,000. 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.
Infant death refers to the death of a child before their first birthday or within 12 months of life. Some of the main causes include premature birth, SIDS, low birth weight, malnutrition and infectious diseases. And lastly, the under-5 mortality rate refers to children who die under the age of 5 years old or within the first 5 years of life. [10]
At the population level, diabetes and high alcohol consumption have a low prevalence. Physical inactivity, smoking and low socioeconomic status (SES) are then the top three preventable causes of early death. Smoking, physical inactivity and low SES account for almost two thirds of all avoidable deaths.
Necrotizing enterocolitis (NEC) is an intestinal disease that affects premature or very low birth weight infants. [4][1] Symptoms may include poor feeding, bloating, decreased activity, blood in the stool, vomiting of bile, multi-organ failure, and potentially death. [1][2] The exact cause is unclear. [1]
