The World Health Organization has unveiled its first comprehensive guidelines for managing childhood obesity, emphasizing family-based, long-term care over medication and surgery as global rates continue to climb among children under ten.
The World Health Organization has issued its first global guidelines for managing obesity in children from 29 days to under 10 years old, marking a shift away from prevention alone and towards structured care for children who are already living with the condition. According to the WHO, the recommendations are designed as an integrated, people-centred approach that weighs benefits, harms, cost, feasibility and the views of children and their carers. The move comes as childhood overweight and obesity continue to rise worldwide, with the organisation saying in 2024 that 35 million children under five were overweight and that 400 million children and adolescents aged 5 to 19 were overweight, including 170 million living with obesity. In Italy, Italia a Tavola noted that 32.3% of children aged three to 10 were overweight in 2024-25, a figure that combines overweight and obesity rather than obesity alone.
The WHO says obesity in childhood should be treated as a chronic and complex disease, not reduced to a question of body weight or body mass index alone. Its guidance places food, movement, sleep, behaviour change and mental health within the same care pathway, with family members or other carers involved throughout. For children aged two and above, the organisation recommends a structured nutritional plan supervised by trained professionals and adapted to age, health status, food preferences and mealtimes. It also stresses that language matters, urging care that is empathetic and free from stigma so that treatment does not become another source of distress.
Physical activity is another central element of the new guidance. The WHO says movement should be built into daily life and matched to the child’s abilities and interests, with the aim of making it sustainable rather than punitive. For children aged one to two, it recommends at least 180 minutes of physical activity spread across the day. From ages three to four, the same total remains in place, with at least 60 minutes at moderate or vigorous intensity. From age five onwards, the target is an average of at least 60 minutes a day of moderate to vigorous activity over the course of the week. Behavioural support should accompany these steps to help children and families change routines gradually and deal with setbacks.
The guidance also widens the definition of success. Alongside weight and BMI, clinicians are urged to consider quality of life, physical and psychological wellbeing, self-esteem and conditions linked to obesity. The WHO says anxiety, depression and eating disorders should be identified and treated when present. Digital tools such as apps, active video games and movement trackers may be used after the age of two, but only under adult supervision and with caution, because the evidence is still weak. The organisation also notes that more than two hours of recreational screen time a day is linked with poorer outcomes, including depression and reduced quality of life.
Where the WHO draws the clearest line is on medicines and surgery. It does not recommend anti-obesity drugs for children aged 0 to 9 years, nor bariatric surgery or devices intended to reduce or control weight in this age group. That caution reflects the thin evidence base: the WHO says it found no studies in children under six and only eight studies from age six upwards, seven involving metformin and one liraglutide. For surgery and weight-control devices, it found no direct evidence at all in children under 10. The broader message of the guideline is that effective care must be coordinated, family-based and long term, but the WHO also makes clear that far more research is still needed before stronger conclusions can be drawn.
