Teenagers do not see their overweight



A recent British study, adolescents have difficulty evaluating their weight: most of them underestimate.

Adolescents have difficulty assessing their weight. Indeed, researchers at the Cancer Research UK organization published the results of their study in the International Journal of Obesity Tuesday, July 7. According to them, 40% of overweight adolescents find that their body size is normal.

Between 2005 and 2012, scientists interviewed 5,000 British teenagers aged 13 to 15 years. In addition to having calculated their body mass index (BMI), they would have asked them if they saw themselves as fat, thin or normal.

The BMI tool that takes into account the weight and size of a person to measure his size, is considered normal if it is between 18.5 and 25, beyond the individuals are either too heavy to be too light. According to survey results, 20% of respondents were overweight and 7% were obese, but nearly 40% of them underestimate their extra weight.

Ethnic origins and socio-professional category of guardians do not influence body perception adolescents. However, girls are better able to judge their weight with age.

Questioning BMI

The researchers explain that this data is important in the context of obesity prevention because “the adolescents with overweight or obese are more likely than others to continue to do the same age adult “. So help them become aware of their weight and to lose their excess weight could reduce the number of obese adults.

However, a recent Australian study may challenge the results of the British survey. Indeed, this study suggests that BMI can not all the time be reliable and that this indicator should be interpreted in different individuals. Based on this premise, the study shows that we can exceed the recommended BMI and be healthy.

Amanda Patterson, lead author of the Australian study, for example, explains that BMI often overestimates the weight of sports (whether amateur or professional). Indeed, the muscle is heavier than fat, people who regularly play sports often weigh heavier than others. Yet they are certainly healthier than sedentary individuals.
