The rate of obesity in young people aged 10-19 is 40 per cent higher in London than the rest of England. While London enjoys a good record compared to the national average in all adult age groups the numbers for youngsters suggest future health problems for London families.
Across England 3.1% of youngsters are classified as obese. But in London that figure jumps to 5.3%. In all other age groups London levels are below the national average.
The data is based upon the Health Survey for England, the Sport England Active Person Survey and BMI information from the Understanding Society study for Health England.
Obesity is measured using the Body Mass Index (BMI). BMI is calculated by dividing your weight in kilograms by your height in meters. The NHS’s easy calculator is here. A BMI of 18.5 to 24.9 is considered normal, healthy weight. Below 18.5 is underweight, above 25 is overweight and 30 and above is obese.
Obesity is broken down into three categories – severely obese, morbidly obese and super obesity. All the children in London are in the first category. Across England there are a small number of teenagers in the other two.
Obesity is linked to a number of health problems, including type-2 diabetes and heart disease.
