In the Czech Republic, half of 13-year-olds have a normal weight, with 15 percent obese. The Ministry of Health's newly launched Buď Fit 24 campaign targets overweight children aged 6-11, involving 1,000 kids in a year-long mobile app program. Pediatricians will monitor their progress, including physical exams. Parents can join via their GP. If successful, health insurance could fund the initiative. The program aims to combat rising childhood obesity, worsened by Covid-related inactivity.
