Infant_mortality

From Wikipedia, the free encyclopedia Infant mortality Infant mortality deaths that occur in the first year of life for 1000 live births. In past times, infant mortality claimed a considerable percentage of children born, but the rates have significantly declined in the West in modern times, mainly due to improvements in basic health care, though high technology medical advances have also helped. Infant mortality rate is commonly included as a part of standard of living evaluations in economics. [1] The infant mortality rate is reported as number of live newborns dying under a year of age per 1,000 live births, so that IMRs from different countries can be compared. A good source for the most recent IMRs as well as under 5 mortality rates (U5MR) is the UNICEF publication ’The State of the World’s Children’ available at http://www.unicef.org/ sowc/. For example, the worst U5MR is 284 in Sierra Leone. (That is, 28% of all children born die before they turn 5 years old.) The 29 countries with the highest U5MRs are in Africa. World infant mortality rate 2007 Infant mortality is defined as the number of deaths of infants (one year of age or younger) per 1000 live births. The most common cause of infant mortality worldwide has traditionally been dehydration from diarrhea. Because of the success of spreading information about Oral Rehydration Solution (a mixture of salts, sugar, and water) to mothers around the world, the rate of children dying from dehydration has been decreasing and has become the second most common cause in the late 1990s. Currently the most common cause is pneumonia. Major causes of infant mortality in more developed countries include congenital malformation, infection and SIDS. Infanticide, abuse, abandonment, and neglect may also contribute to infant mortality Related statistical categories: • Perinatal mortality only includes deaths between the foetal viability (22 weeks gestation) and the end of the 7th day after delivery. • Neonatal mortality only includes deaths in the first 28 days of life. • Post-neonatal death only includes deaths after 28 days of life but before one year. • Child mortality includes deaths within the first five years after birth. Comparing infant mortality rates The infant mortality rate correlates very strongly with and is among the best predictors of state failure.[2] IMR is also a useful indicator of a country’s level of health or development, and is a component of the physical quality of life index. Some claim that the method of calculating IMR may vary between countries based on the way they define a live birth. The World Health Organization (WHO) defines a live birth as any born human being who demonstrates independent signs of life, including breathing, voluntary muscle movement, or heartbeat. UNICEF uses a statistical methodology to account for reporting differences among countries. "UNICEF compiles infant mortality country estimates derived from all sources and methods of estimation obtained either from standard reports, direct estimation from micro data sets, or from UNICEF’s yearly exercise. In order to sort out differences Infant mortality rate Infant mortality rate (IMR) is the number of newborns dying under a year of age divided by the number of live births during the year. The infant mortality rate is also called the infant death rate. It is the number of 1 From Wikipedia, the free encyclopedia between estimates produced from different sources, with different methods, UNICEF developed, in coordination with WHO, the WB and UNSD, an estimation methodology that minimizes the errors embodied in each estimate and harmonize trends along time. Since the estimates are not necessarily the exact values used as input for the model, they are often not recognized as the official IMR estimates used at the country level. However, as mentioned before, these estimates minimize errors and maximize the consistency of trends along time."[3] While the United States reports every case of infant mortality, it has been suggested that some other developed countries do not. A 2006 article in U.S. News & World Report claims that "First, it’s shaky ground to compare U.S. infant mortality with reports from other countries. The United States counts all births as live if they show any sign of life, regardless of prematurity or size. This includes what many other countries report as stillbirths. In Austria and Germany, fetal weight must be at least 500 grams (1 pound) to count as a live birth; in other parts of Europe, such as Switzerland, the fetus must be at least 30 centimeters (12 inches) long. In Belgium and France, births at less than 26 weeks of pregnancy are registered as lifeless.[4] And some countries don’t reliably register babies who die within the first 24 hours of birth. Thus, the United States is sure to report higher infant mortality rates. For this very reason, the Organization for Economic Cooperation and Development, which collects the European numbers, warns of head-to-head comparisons by country."[5] However, all of the countries named adopted the WHO definition in the late 1980s or early 1990s.[6] Historically, until the 1990s Russia and other countries of the former Soviet Union did not count as a live birth or as an infant death extremely premature infants (less than 1,000 g, less than 28 weeks gestational age, or less than 35 cm in length) that were born alive (breathed, had a heartbeat, or exhibited voluntary muscle movement) but failed to survive for at least 7 days.[7] Although such extremely premature infants typically accounted for only about 0.005 of all live-born children, their exclusion from both the numerator and the denominator in the reported IMR led to an estimated 22%-25% lower reported IMR.[8] In some cases, too, perhaps Infant mortality because hospitals or regional health departments were held accountable for lowering the IMR in their catchment area, infant deaths that occurred in the 12th month were "transferred" statistically to the 13th month (i.e., the second year of life), and thus no longer classified as an infant death.[9] Another challenge to comparability is the practice of counting frail or premature infants who die before the normal due date as miscarriages (spontaneous abortions) or those who die during or immediately after childbirth as stillborn. Therefore, the quality of a country’s documentation of perinatal mortality can matter greatly to the accuracy of its infant mortality statistics. This point is reinforced by the demographer Ansley Coale, who finds dubiously high ratios of reported stillbirths to infant deaths in Hong Kong and Japan in the first 24 hours after birth, a pattern that is consistent with the high recorded sex ratios at birth in those countries and suggests not only that many female infants who die in the first 24 hours are misreported as stillbirths rather than infant deaths but also that those countries do not follow WHO recommendations for the reporting of live births and infant deaths.[10] Another seemingly paradoxical finding is that when countries with poor medical services introduce new medical centers and services, instead of declining the reported IMRs often increase for a time. The main cause of this is that improvement in access to medical care is often accompanied by improvement in the registration of births and deaths. Deaths that might have occurred in a remote or rural area and not been reported to the government might now be reported by the new medical personnel or facilities. Thus, even if the new health services reduce the actual IMR, the reported IMR may increase. Global infant mortality trends For the world, and for both Less Developed Countries (LDCs) and More Developed Countries (MDCs), IMR declined significantly between 1960 and 2001. World infant mortality rate declined from 126 in 1960 to 57 in 2001.[11] However, IMR remained higher in LDCs. In 2001, the Infant Mortality Rate for Less Developed Countries (91) was about 10 times 2 From Wikipedia, the free encyclopedia Rank 1 2 3 4 5 219 220 221 222 223 Country Angola Sierra Leone Afghanistan Liberia Niger Hong Kong Japan Sweden Bermuda Singapore Infant mortality rate (deaths/1,000 live births) 180.21 154.43 151.95 138.24 116.66 2.92 2.79 2.75 2.46 2.31 Infant mortality average, much less than those among the more developed countries.

For Least Developed Countries, the Infant Mortality Rate is 17 times as high as it is for More Developed Countries.
