Globally, childhood obesity has become one of the most common chronic health conditions among young people.

Indeed, research indicates that about 30% of Malaysian children are estimated to have excess weight – a worrying trend that experts say is appearing earlier in life, even before children enter primary school. According to consultant paediatrician Dr Ng Hui Ying, some preschool-aged children are already showing signs of health issues linked to early obesity. These include sleep problems, difficulty concentrating, and reduced attention in class. “Malaysia’s children are facing early-onset obesity, even before primary school,” she said, noting, however, that weight is often a sensitive topic for families. “Avoiding the discussion can delay screening and intervention. Infants or young children who gain weight rapidly may need evaluation for underlying risk factors.” Globally, childhood obesity has become one of the most common chronic health conditions among young people. The American Academy of Pediatrics estimates 14.4 million children and adolescents worldwide are living with obesity. Local research shows the problem has grown steadily over the decades. A 2025 meta-analysis published in Clinical and Experimental Paediatrics found obesity prevalence among Malaysian children increased from 8.4% in 1990 to 14.5% in the 2020s. Paediatricians use body mass index (BMI) charts to assess whether a child’s weight falls within a healthy range. Warning signs of potential health conditions among children who are overweight or obese include high blood pressure, darkened skin patches in body folds, excessive thirst, frequent urination, snoring at night, daytime sleepiness and difficulty concentrating. The risk of health issues also increases if there is a family history of conditions such as diabetes, hypertension or heart disease, as well as maternal diabetes during pregnancy or abnormal birth weight, Ng said. Overweight or obese children are more likely to experience bullying, depression and anxiety.

Studies have also shown that children who are overweight or obese are more likely to experience bullying, depression and anxiety, highlighting the importance of early intervention. Ng highlighted that most cases of childhood obesity are linked to lifestyle habits shaped by the child’s environment. Genetic, hormonal or metabolic causes may also play a role. As such, daily habits such as diet, physical activity and limiting screen time are key. The American Academy of Pediatrics suggests that children who watch more than two hours of television daily face a 42% higher risk of obesity, as prolonged screen time encourages snacking, reduces physical activity, and shortens sleep. Malaysian data shows similar concerns: the National Health and Morbidity Survey 2024 found that only about half of children consume all of the recommended five food groups daily. Meanwhile, 63% of adolescents drink more than one sugary beverage a day and 75% exceed recommended fat intake. As such, family habits, too, are crucial. “Children are more likely to reach a healthy weight when parents respond to hunger and fullness cues, model good habits, and maintain routines,” Ng noted. Encouraging balanced meals, limiting sugary drinks, and promoting regular physical activity can help children develop healthier eating patterns. Ultimately, “obesity is a chronic condition that needs ongoing care”, Ng concluded, stressing that regular paediatric check-ups allow doctors to monitor growth, identify underlying causes, and guide families on lifestyle changes.
