Researchers Identify Gene Linked to Obesity in Children

Approximately 70 per cent of the human population carries at least one variant of this polymorphism, which is associated with an increased risk of obesity

Researchers have identified a common gene variant that increases the risk of obesity in children.
In a study published in Obesity journal, the researchers from University of Columbia found that a specific variant (single nucleotide polymorphism) of a gene called “FTO” affects eating behaviour that may be predictive of subsequent weight gain in children, who are at obesity risk.
“Early identification of the physiology and behaviours that constitute early risk factors for subsequent weight gain will help inform best practices for intervention and prevention of obesity in children,” said study author Michael Rosenbaum, a professor at Columbia University.
“This study shows that even before the development of an obese phenotype, children at risk, in this case by virtue of a common genetic variant, exhibit increased food intake,” added Rosenbaum.
For the study, the researchers included 122 children in the 5-10 year age group.
Obesity can now be cured by our body's natural weighing scales.

The study discovered that children who are at risk of obesity due to this genetic variant had an increased calorie intake which may contribute to gaining excess weight.
“Even though 65 calories is not a lot per se, if this pattern generalized to multiple meals per week or day, this increased caloric intake can add up over time and may contribute to gaining excess weight,” said Rosenbaum.
According to the researchers, the report could be used to further study children at obesity risk for other reasons.
“The ultimate goal is to prevent the at-risk child or the child who has obesity from becoming an adult with obesity,” added Rosenbaum.

Parents, please take note. Among the lifestyle habits that influence the risk of overweight and obesity in children, watching television is the worst, suggests new research.

“Identifying habits linked to overweight and obesity in the early stages of life can help us to define preventive strategies against other conditions, such as cardiovascular and metabolic diseases during adulthood,” said lead author of the study Rowaedh Bawaked, researcher at the Hospital del Mar Medical Research Institute in Spain.

The researchers analysed five lifestyle habits: physical activity, sleep time, television time, plant-based food consumption and ultra-processed food consumption.

The study, published in the journal Pediatric Obesity, was based on data from 1,480 children.

Parents were asked to complete various questionnaires on the children’s lifestyle habits at four years of age.

To calculate the health impact of these habits, the researchers measured the children’s body mass index (BMI), waist circumference and blood pressure at four and seven years of age.

Children who were less active and spent more time in front of the television at four years of age were at greater risk of being affected by overweight, obesity and metabolic syndrome at seven years of age, showed the findings.

The researchers also measured the time spent by the children on other sedentary activities, such as reading, drawing and doing puzzles. However, these activities did not appear to be associated with overweight or obesity.

“When children watch TV, they see a huge number of advertisements for unhealthy food,” said co-leader of the study Dora Romaguera from Barcelona Institute for Global Health in Spain.

“This may encourage them to consume these products,” Romaguera said.

Ultra-processed foods, such as pastries, sweet beverages and refined-grain products, are high in sugar, salt and saturated fat and low in nutritional value.

The study showed that high intake of these products at four years of age was associated with a higher BMI at seven years of age.

Moreover, television viewing “discourages physical activity and interrupts sleep time”, explained Silvia Fernandez, a post-doctoral researcher at Barcelona Institute for Global Health.

As the researchers noted, adequate sleep time in early childhood is essential for weight control later in childhood.

The study concluded that adult health depends on the establishment of healthy lifestyle habits during childhood: limited television time, extracurricular physical activity, getting enough hours of sleep, eating lots of vegetables and avoiding ultra-processed foods. (IANS)
