World Birth Defects Day: Why are Birth Defects So Common in Low and Middle-Income Countries?

Who is at risk of serious birth defects? Almost 9 out of 10 children living in low/middle-income countries are born with serious birth defects, said World Health Organization (WHO)

Children born with birth defects tend to face a higher risk of health problems throughout their life.

The World Health Organization (WHO) has underlined the urgent need for countries in the Southeast Asia region and globally to strengthen health systems to prevent, detect, manage and care for birth defects to mark this year's World Birth Defects Day (March 3).

Global Birth Defects

Globally, an estimated 8 million newborns are born with a birth defect every year. Nine out of every 10 children born with a serious birth defect are in low and middle-income countries, said the global health body.

The most common severe birth defects are heart defects, neural tube defects and down syndrome, but there are many others, which can be caused by one or more genetic, infectious, nutritional or environmental factors.

"In the Southeast Asia region, birth defects are the third most common cause of child mortality, and the fourth most common cause of neonatal mortality, accounting for 12 percent of all neonatal deaths. Between 2010 and 2019, birth defects increased as a proportion of child mortality in the region, from 6.2 percent to 9.2 percent, and in four countries, birth defects now contribute to more than 20 percent of under-five mortality," said Poonam Khetrapal Singh, WHO Regional Director for Southeast Asia.

Singh said that birth defects contributed to at least 117,000 deaths in the region, equal to around 22 percent of the global total in 2019.

Quiz on Birth Defects
Birth defects are structural or functional abnormalities that happen while a baby is developing in the mother’s body. Most birth defects occur during the first trimester of pregnancy. Main categories of birth defects include structural birth defects and functional/developmental birth defects.

"Since 2014, WHO has supported all countries of the region to drive rapid, sustained reductions in maternal, newborn and child mortality, which has included targeted action to prevent, detect, manage and care for birth defects. All member states have initiated hospital-based birth defect surveillance and are implementing national action plans to prevent and manage birth defects," she added.

Six member states - Bangladesh, Bhutan, India, Maldives, Myanmar and Nepal - continue to support a WHO-developed online database to better track birth defects.
