Mains Level: These days, Obesity is a serious health issue among children.
A new study in The Lancet
- The study was released on World Obesity Day on October 11
- The study looked at BMI (body mass index) trends in 200 countries from 1975-2016
(a) Obese Population
- It has found that the number of obese girls in age group 5-19 has risen from 5 million to 50 million in 40 years
- And that of boys from 6 million to 74 million.
(b) Underweight Polpulation
- The researchers say that if current world trends continue, “obese” will soon be more common than “underweight”
Results of the study on India
- India has among the largest shares of underweight children and teenagers
- And at the other end, it is part of a trend that has seen the number of obese under-20s worldwide rising tenfold in 10 years
- In India, the prevalence of obesity is between 1-2 %
- The prevalence of mild to severe underweight under-20s in India is 22.7% among girls and 30.7% among boys
Why is obesity increasing among children?
- The middle class and upper middle class in India have fewer children and tend to overfeed them under the pretext of pampering
- As per the Lancet study, the percentage is between 1-2 in India but these will increase as social structures are changing in India
Body Mass Index(BMI)
- The body mass index (BMI) or Quetelet index is a value derived from the mass (weight) and height of an individual
- The BMI is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m2, resulting from mass in kilograms and height in metres
