Indian children growing taller, heavier

PUNE, Sept 22: Indian children are growing taller and heavier than earlier generations. Compared to eight years ago, 18-year-old boys and girls from the country’s middle and upper classes are 3 cm and 1 cm taller, respectively, according to the latest growth charts published this year for children aged five to 18. The growth figures — last updated in 2007, using data collected more than two decades ago — reveal upsides and downsides.

The new charts reflect the rise of taller and heavier urban children. Girls are taller than earlier, but stop growing once they hit puberty, which is happening sooner.

“Boys and girls are heavier than before, and modern India is seeing a huge epidemic of obesity,” said Vaman Khadilkar, consultant paediatric endocrinologist at Jehangir Hospital, Pune, and convener of the Indian Academy of Pediatrics’ (IAP) growth-chart committee.

Convened in January 2014, the committee worked on the revisions and published its findings and charts in the jourl ‘Indian Pediatrics’ this year. The new charts are based on contemporary data on growth and development of 33,991 children of upper and middle socio-economic groups living in 14 Indian cities.

Growth charts answer questions that often plague parents: Is my child growing well or not? Is she gaining enough weight and height? The problem with those questions is, no matter how much we fuss, worry and compare with peers, we continue to doubt the answers.

A simple way to get rid of ambiguity and anxiety is to use a growth chart - an old but little-used statistical tool. Growth charts are graphs that show the ideal weight and height of a child at a given age. Such charts are also great diagnostic tools, as they not only let you monitor your child’s growth in normal conditions, they also make it easier to spot irregularities.

The charts are like a “standard that every child should attain and if she is not doing so, we need to find the reasons”, says Sanjay Wazir, director of neotology, Cloudnine Hospital, Gurgaon. He cites the example of a baby whose growth curve started faltering from the age of one, despite adequate nutrition. It emerged that the child had celiac disease.

Over the past few decades, for a certain section of society, good nutrition has ceased to be a problem. Fincial security has not only made sure that our plates are full, it has also caused a change in dietary patterns for many Indians.

As a result, obesity and the huge burden of lifestyle diseases that tag along have become rampant, as IndiaSpend previously reported.

Obese children have a greater chance of becoming obese adults burdened by lifestyle disorders. “The new growth charts are the best tools to diagnose obese and overweight [children] sooner,” said Khadilkar.

However, while some Indian children are overweight and obese, many are malnourished. So, how do these charts help children from both categories, and are they valid for poorer children, since they were created using data on children from the upper and middle socio-economic classes? Paediatricians advocate the use of IAP charts irrespective of socio-economic group.

“These charts should be used across all socio-economic classes, as they are prepared from a set of children who are believed to be living in an optimal nutritiol environment in India,” said Archa Dayal Arya, senior consultant paediatric endocrinologist, Sir Gangaram Hospital, New Delhi.

If paediatricians want to account for the nutritiol divide between rich and poor and urban and rural children, “presently no growth charts are available that account for them or adjust for them”.

We do not have options other than to use one of these charts, said Neelam Kler, chairperson, Department of Neotology, Institute of Child Health, Sir Ganga Ram Hospital, New Delhi. Wazir concurred. “Given the limitation of ideal growth charts, the IAP charts are our best bet,” said Wazir.

The World Health Organisation (WHO) also provides growth charts for children in the 5-18 age group to be used worldwide. But Khadilkar and his associates on the growth-chart committee believe IAP charts are better suited for Indian kids.

“Growth patterns differ amongst different populations, especially in children above the age of five, as nutritiol, environmental and genetic factors, and timing of puberty seem to play a major role not only in the attainment of fil height but also in the characteristics of the growth curve.” they write in their paper.

Hence, the need for country-specific growth charts. Many paediatricians appear to agree with this view. For children under five, IAP also recommends WHO charts, which appear to have universal acceptability among the paediatricians.

While there may exist a debate about which charts to use, India does not have a great track record in monitoring children’s growth. “Although, there is no tiol data available, my estimate is only about 20-30 percent pediatricians plot growth”, said Khadilkar.

Parents and schools must also pitch in. Many schools record height and weight of children annually, but they fail to connect with a doctor to plot and interpret this data on a chart.

For younger children, especially under the age of two, frequent measurements are needed. Beyond the age of five, annual measurements are enough. Rajesh Chandwani, a pediatrician and professor at IIMA has developed an app called Babysteps, to monitor the growth and development of children under the age of two. Chandwani said older children, too, require height and weight monitoring, as many “growth-related disorders and nutritiol deficiencies can be detected and maged”.

In their concern about their children looking smaller than their peers, sometimes parents give food supplements to their children. This is not a good idea because it may “lead to diabetes, blood pressure and heart attacks later in life, especially for babies who were born small at birth,” said Wazir. (IANS)
