Childhood obesity is emerging as a major health concern in Malaysia, with one in five children now classified as obese. Doctors are reporting illnesses once considered adult-onset appearing in increasingly younger patients.
Prof Dr Muhammad Yazid Jalaludin, senior consultant paediatric endocrinologist at Universiti Malaya Medical Centre, said clinics are seeing children with a wide range of complications. “Beyond insulin resistance and type 2 diabetes, we are seeing fatty liver, high blood pressure, abnormal cholesterol, early puberty, and sleep-disordered breathing,” he said, noting that these conditions are now affecting primary school-aged children and significantly raising long-term health risks.
The latest National Health and Morbidity Survey shows that 23.1% of Malaysian children were overweight or obese in 2024. Prof Muhammad Yazid highlighted that metabolic diseases are now being diagnosed in adolescents and even pre-teens, about a decade earlier than before, with his youngest patient just eight years old. Early onset increases the lifetime risk of heart disease, stroke, kidney failure, and vision loss, while also placing added pressure on healthcare services, especially in areas with limited specialist access.
Obesity also carries serious mental health implications. “Many children face poor body image, low self-esteem, anxiety, and social isolation,” he said, noting that weight-related bullying in schools can exacerbate unhealthy habits and reduce physical activity. Doctors are increasingly incorporating psychological support into treatment plans for obese children.
Experts link the rise in childhood obesity to lifestyle and environmental factors, including high consumption of sugary drinks and fast food, frequent snacking, sedentary behaviour, excessive screen time, and poor sleep patterns. Urbanisation, academic pressures, and fewer opportunities for outdoor play have also contributed. Parents are advised to monitor their children’s growth and seek medical advice if warning signs of unhealthy weight gain appear. Children are considered overweight if their BMI exceeds the 85th percentile and obese if above the 95th percentile, based on WHO growth charts. Signs to watch for include rapid weight gain, increasing waist size, breathlessness during light activity, reduced physical activity, or darkened skin folds (acanthosis nigricans), which may indicate insulin resistance.
Prof Muhammad Yazid emphasised that prevention and early intervention are key. Families can begin with simple lifestyle changes such as reducing sugary drinks and processed snacks, increasing fruits, vegetables, and whole grains, practising portion control, ensuring at least 60 minutes of daily physical activity, limiting screen time, and maintaining regular meal schedules and nine to eleven hours of sleep. “Parents should focus on health, strength, and energy rather than weight alone. Role-modelling healthy habits is a powerful influence on children,” he said.
Malaysia’s National Strategic Plan for Non-Communicable Diseases and school health programmes support these measures, though experts stress that reversing childhood obesity will require coordinated action across education, urban planning, food policy, and healthcare.
