THE NEED  FOR NEW BORN SCREENING IN INDIA

By : Dr. Rajan R Patil. Epidemiologist. School of Public Health,SRM University, Chennai.

Genetics is essentially public health than than therapeutic.The  strength of genetics  lies in prevention of disease and not its cure. It  therefore needs to be taken up as public health measure  for prevention of physical and mental handicap The uniqueness of genetic disorders is variety and rarity. In medicine roficiency comes by numbers, whereas most individual genetic disorders are rare having the prevalence of 1:5000-15000 births, or even  more.

INDIAN CONTEXT
Out of every 100 babies born in this country annually, 6 to 7 have a birth defect. In Indian context, this would translate to 1.7 million birth defects annually and would account for 9.6 per cent of all newborn deaths.With a large birth cohort of almost 26 million per year, India would account for the largest share of birth defects in the world. This would translate to an estimated 1.7 million babies born with birth efects annually. In the study conducted by National Neonatology Forum, congenital  malformations were the second commonest cause (9.9%) of mortality among stillbirths and the fourth commonest  cause (9.6%) of neonatal mortality and that accounted for 4 per cent of under-­ ve mortality.

 Birth defects account for 9.6% of all new-born deaths and 4% of under five mortality. According to March of Dimes, 2006, out of every 100 babies born in this country annually, 6 to 7 have a birth defect. In Indian context, this would translate to 17 lakhs birth defects annually. Development delays affect at least 10% children and these delays if not intercepted timely may lead to permanent disabilities including cognitive, hearing or vision. 

GLOBAL CONTEXT

Globally, about 7.9 million children are born annually with a serious birth defect of genetic or partially genetic origin which accounts for 6 percent of the total births . At least 3.3 million children under ­ ve years of age die from birth defects every year and another 3.2 million of those who survive may be isabled for life. Cutting across countries and  their economic status, 64.3 infants per thousand live births are born annually with birth defects
