| mortality rate, neonatal | The number of children dying under 28 days of age divided by the number of live births that year. The neonatal mortality rate in the united states, which was 8.4 per 1,000 live births in 1980, declined to 5.8 per 1,000 live births in 1990. (12 Dec 1998) |
|---|---|
| hospital mortality | A vital statistic measuring or recording the rate of death from any cause in hospitalised populations. (12 Dec 1998) |
| standardised mortality ratio | The ratio of the number of events observed in a population to the number that would be expected if the population had the same distribution as a standard or reference population. (05 Mar 2000) |
| neonatal mortality rate | The number of children dying under 28 days of age divided by the number of live births that year. The neonatal mortality rate in the united states, which was 8.4 per 1,000 live births in 1980, declined to 5.8 per 1,000 live births in 1990. (12 Dec 1998) |
| infant mortality | Perinatal, neonatal, and infant deaths in a given population. (12 Dec 1998) |
| infant mortality rate | The number of children dying under a year of age divided by the number of live births that year. The infant mortality rate in the united states, which was 12.5 per 1,000 live births in 1980, fell to 9.2 per 1,000 live births in 1990. (12 Dec 1998) |
| type II mortality | <epidemiology> A mortality schedule in which all hosts are assumed to die at a constant rate. This constant rate is equal to the inverse of the life expectancy. (05 Dec 1998) |
| type I mortality | <epidemiology> A mortality schedule in which all hosts are assumed to live for a fixed number of years equal to the life expectancy. (05 Dec 1998) |
| foetal mortality rate | <epidemiology> The ratio of foetal deaths divided by the sum of the births (the live births + the foetal deaths) in that year. In the United States, the foetal mortality rate plummeted from 19.2 per 1,000 births in 1950 to 9.2 per 1,000 births in 1980. (12 Dec 1998) |
