Spain's Youth Obesity Crisis
New data shows over half of Spain is overweight, with obesity rising fastest among 18-24 year-olds—a 40%+ increase in recent years. This trend reflects a global challenge and highlights the critical need for early, sustained interventions in youth health before the problem becomes entrenched.
While the overall adult obesity rate in Spain has seen a slight dip, the sharp increase among young adults is a significant cause for concern. Data from HM Sanchinarro University Hospital indicates that obesity in the 18-24 age bracket climbed from below 5% to 7% between 2020 and 2023 alone. There are notable regional differences across the country. The Canary Islands report the highest obesity rate at 20.6%, with Murcia close behind at 20.1%. In contrast, the Community of Madrid records the lowest level of obesity in Spain, at 10.3%. A key contributing factor is the rise of an "active-sedentary" lifestyle among Spanish youth. This phenomenon describes a situation where young people may engage in some sport but spend the majority of their leisure time in sedentary activities, often involving screens. More than 60% of Spanish adolescents spend over two hours per day in front of a screen on weekdays, a figure that jumps to over 85% on weekends. This trend has tangible health consequences. Among children and adolescents, there are an estimated 154,000 cases of hypertension linked to high body mass index, 225,000 with high triglyceride levels, and 433,000 suffering from fatty liver disease. In response to the broader issue of childhood and adolescent obesity, the Spanish government, in partnership with the Gasol Foundation, has launched the National Strategic Plan for the Reduction of Childhood Obesity. The plan, which includes over 200 measures, aims to reduce excess weight in children and adolescents by 25% by the year 2030. Interestingly, the crisis among young adults contrasts with a more hopeful trend in younger age groups. Spain is one of the few countries to see a recent decline in obesity and overweight rates for those aged 10 to 19. The prevalence in this demographic fell from 32.5% in 2010 to 30.5% in 2025.
