Obesity knows “an increase which is strong in the youngest age groups”, summarized Annick Fontbonne, epidemiologist at Inserm, during a press conference on Monday.
The researcher detailed a study she conducted on the proportion of obese or overweight adults in France in 2020.
According to this study, carried out by survey of around 10,000 people representative of the population, nearly half of the French (47%) weigh too much compared to medical recommendations.
Among them, a sixth of the French (17%) would be obese, that is to say at a level of weight considered unhealthy as opposed to simply being overweight.
Etude comparative
This study is a reference on the subject of obesity and overweight in France, as it has been carried out regularly since the end of the 1990s.
It is therefore interesting for evaluating the evolution of obesity and overweight. However, if the latter tends to stabilize or even decrease for a decade, obesity continues to affect more and more French people.
These results were already generally known, because they had been made public last year by the League once morest Obesity, an association which relaunched this study following a period of inactivity.
They are now the subject of a publication in a journal, the Journal of Clinical Medicine, and in the meantime, the researchers were able to refine their conclusions.
Rise of the youngest and geographical distribution
They therefore noticed that the rise in obesity particularly affected 18-24 year olds. The latter are, in absolute terms, the least affected age group with one-tenth (9.2%) obese, but this share has quadrupled over the past twenty years.
Another notable conclusion, obesity is more or less common depending on the region: it affects more than 20% of people questioned in Hauts-de-France or Grand Est.
This geographical distribution corresponds in particular to socio-economic realities, with the poorest regions tending to be more affected.
“People are not ‘addicted’ to bad food but they are encouraged to buy it because it is cheaper”notes Ms. Fontbonne. “Good quality foods, foods that are said to be healthy, are generally more expensive.”
