Experts: High-Risk Newborns Susceptible to Disability, Delayed Development

Factors like under-nutrition and mental stress during pregnancy has an impact on infants development and results in high-risk newborns.

Babies born with low birth weight and other complications at birth, termed as high-risk newborns are more prone to developmental delays and other disabilities than healthy newborns, say Indian researchers.

The researchers highlighted the gap in early diagnosis in rural settings. Developmental delay refers to a child not achieving 'developmental milestones' at the right age.

Scientists Discover Genes Linked to Low Birth Weight, Adult Shortness, Later Diabetes Risk
Four new regions that contribute to low birth weight have been identified by scientists.

These 'milestones' refer to sets of functional skills or age-specific tasks that most children can do in a certain age-range.

Delays may be in physical ability or cognitive ability. Identifying such lags and intervening early can prevent disability to a large extent in children and reduce the burden in India, say experts.

"Incidence of developmental delay among high-risk newborns is significantly high with low birth weights, prematurity and neonatal illnesses being major contributors," said, Nandita Chatterjee, developmental pediatrician.

Low Birth Weight Kids Too, Should 'Move'
Female mice whose growth was restricted in the womb had lower birth weights, were less active later in their lives, and were at a greater risk of suffering from obesity, a new study found

For example, if the normal age-range for walking is 9 to 15 months and a child isn't walking by 20 months then this would be considered a development delay, explained Partha De, population studies expert from Kolkata's Indian Statistical Institute.

Chatterjee said high-risk newborns are those who are vulnerable to brain damage and neuro-developmental deficits in later life. They include babies with very low birth weights (LBW), premature babies, infants with severe infections, severe jaundice or any newborn who is very sick.

Study Finds Link Between Low Birth Weight And H1N1
Two research papers have shown that women who contracted H1N1 were more likely to give birth to lower birth weight babies as compared with women who had influenza-like illness .

"These children with developmental delay are not being diagnosed early in the rural areas, leading to developmental challenges and disability in later life," said Chatterjee, head of the department of pediatrics, IQ City Medical College, Durgapur, West Bengal.

The experts' observations are based on a study done in West Bengal's Purulia district, one of the most backward and impoverished regions of the state located in the remote, tribal belt.

Low Birth Weight Tied To Autism Risk
A new study has found that low birth weight is a key environmental factor which leads to the development of autism spectrum disorder (ASD) in children.

Published in 2015 in the Journal of Public Health Research, the study was carried out with field-based tracking and neuro-developmental screening of high-risk newborns discharged from the Special Neonatal Care Unit (SNCU) of the Purulia District Hospital.

The assessment was done from January 2010 to June 2012 in collaboration with UNICEF.

"In this study, we examined children mostly up to three years of age. We picked up a good number of children with early signs of developmental delay and evolving cerebral palsy," said, Chatterjee.

On screening 427 children, 31.6 percent were found to have some developmental delay/challenges.

The spectrum of challenges included motor deficits (difficulty in mobility) such as cerebral palsy, cognitive deficits (intellectual development) like mental retardation, hearing and speech defects, visual defects, behavioral defects including autism, attention deficit hyperactivity disorder (ADHD) and the like.

Further, researchers also identified gender disparity in healthcare in the district.

"A high male-to-female ratio was seen among the developmentally challenged children examined, as well as among the babies admitted to and discharged from the SNCU."

"This may reflect the fact that greater importance is attached to medical care for the male child," said Chatterjee.

According to De, reasons like under-nutrition and mental stress on the pregnant mother also impacts the infant's development.

"Once a disability develops in a child, the extent of the problem multiplies in medical, social and economic aspects."

"If we could determine the major contributing factors to developmental delays and reduce them through early intervention and treatment, the burden of developmental challenges and ultimate child disability could be minimized in India," De pointed out.

India has 2.04 million disabled children aged between 0 and 6 years. Around 71 percent of them - 1.45 million are in rural areas, as per the 2011 Census.

Given the magnitude of the problem, it becomes important to develop guidelines to provide services for the effective diagnosis, care, understanding the cause, management, treatment and prevention of various types of developmental challenges among children in India, De noted.
