India in 2015 had more deaths among children under five than any other country; and had large disparities in the under-five mortality rate between richer and poorer states; but according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health.
In the study, published in The Lancet Global Health, the researchers analyzed state-level Indian data; on the causes of death among children under five for the years 2000-2015. They found that India made great progress during the period, reducing annual mortality among children under five from 2.5 million in 2000 to 1.2 million in 2015.
But among India’s states, great disparities remained: The highest mortality rate, in Assam, a state in northeastern India; was more than 7 times that in the western state of Goa. Although most under-five deaths were due to preterm complications; preventable infectious diseases featured prominently as causes of death in higher-mortality states.
Government health surveys
India can accelerate its reduction of under-five mortality rates by scaling up vaccine coverage; and improving childbirth and neonatal care, especially in states where mortality rates remain high”; said Li Liu, PhD, assistant professor in the Department of Population, Family and Reproductive Health; at the Bloomberg School, study co-lead author.
The research team included scientists from the Bloomberg School, the London School of Hygiene & Tropical Medicine; World Health Organization (WHO), Indian government health and vital records agencies and other institutions. The other co-lead author was Yue Chu, MSPH, a research associate; but in the Department of International Health at the Bloomberg School.
Using data sources such as Indian government health surveys; the team assessed total mortality, mortality rates and causes of mortality for children under five in India’s 25 major states. Such large analyses help governments gauge their progress and allocate resources as needed to reach public health goals.
Under-five mortality rate
These goals include one of the United Nations Millennium Development Goals (MDG) set in the year 2000: to reduce the under-five mortality rate in 2015 to one-third of the 1990 figure. For India that would have meant reducing the under-five mortality rate to 39 deaths per 1,000 live births. The analysis showed, however, that despite great progress since 1990–and even since 2000 when the under-five mortality rate was 90.5 deaths per 1,000 live births India in 2015 was still well above the MDG target, at 47.8 deaths per 1,000 live births.
Most (57.9 percent) of deaths among Indian children under five in 2015 occurred in the first four weeks of life–the neonatal period. Countrywide, the leading cause of death for children under five was preterm birth complications, which accounted for 27.5 percent of the mortality total.
But second on the list for cause-of-death was pneumonia (15.9% of deaths), and infectious illnesses were more often among the top causes in the poorer, high-mortality states. “Noncommunicable diseases such as preterm birth complications and congenital abnormalities were usually the leading causes in states with low under-five mortality,” said Li Liu, PhD
