Minister of Health Paulette Lenert provided this information in her response to a parliamentary enquiry from MP Nancy Kemp-Arendt from the Christian Social People's (CSV) party.

Minister Lenert further underlined that there is missing data from the 2019/2020 school medical examinations, which fell short due to the pandemic. Nevertheless, a number of facts can still be established with the help of existing records.

In 2019, 9.75% of primary school pupils were considered overweight, a number which increased to 9.91% in 2020. Statistics from secondary schools mostly align with this tendency: 9.07% in 2019 and 9.35 in 2020.

4.15% of primary school children examined in 2020 were considered obese, thereby remaining the same as during the previous year. For students in secondary schools, however, the obesity rate increased from 5.25 to 7.48% in the span of a year. In general the rate for obese children has seen a slight increase over the past decade but Minister Lenert underlined that there are no signs of an exponential increase.

Data from primary schools shows that the rate for overweight children increases with age: from 3% in Cycle 1 to 6.39% in Cycle 4. The same evolution continues in secondary schools, where the rate for overweight children begins at 8.69% in 7e classes and increases to 10.84% in 3e classes. Obesity ranges from 4.68% in 7e classes to 7.8% in 3e classes.
