Overweight children are those whose body weight is significantly higher than what is considered healthy for their age and height. This condition is often measured using the Body Mass Index (BMI), which compares weight to height. Factors contributing to childhood overweight include poor diet, lack of physical activity, and genetic predisposition. Being overweight can lead to various health issues, such as diabetes, heart problems, and low self-esteem. It is important for parents and caregivers to encourage healthy eating habits and regular exercise to help children maintain a healthy weight. Schools and communities can also play a role in promoting physical activity and nutrition education.
