Childhood Obesity: Causes and Prevention Strategies

Childhood obesity is a growing concern worldwide. According to the World Health Organization (WHO), approximately 41 million children under the age of five were overweight or obese in 2016. Children who are obese are at an increased risk of developing health problems, including Type 2 diabetes, heart disease, and even cancer. This article explores the causes of childhood obesity and strategies for prevention.

Causes of childhood obesity

There are several contributing factors to childhood obesity including genetic, behavioral, and environmental factors. Many children have a genetic susceptibility to obesity, but environmental factors can significantly contribute to the development of obesity. The following are some of the leading causes of childhood obesity.

1. Eating habits – Children who consume high-calorie, high-fat, and high-sugar foods regularly are at risk of obesity. Parents who allow their children to eat unhealthy foods often contribute to the development of obesity.

2. Reduced physical activity – With the growing dependence on technology and sedentary lifestyle, many children are not getting enough physical activity. This sedentary lifestyle can lead to obesity, especially when coupled with unhealthy eating habits.

3. Parental influence – Parents play a significant role in their children’s eating and physical activity habits. A sedentary lifestyle, unhealthy eating habits, and a lack of physical activity are often mirrored by the children.

Prevention Strategies

1. Encourage physical activity – Children should be encouraged to engage in physical activity, both structured and unstructured. Physical activity can include playing outside, participating in sports or dance classes, and walking or cycling to school.

2. Promote Healthy Eating – A healthy balanced diet rich in fruits, vegetables, whole grains, lean proteins, and low-fat dairy products can help prevent obesity. Parents should limit the consumption of processed, high-fat and sugary foods and encourage their children to have a healthy diet.

3. Engage with their health care providers – Parents need to discuss their children’s growth with their health care providers. Health care providers can assess their body mass index (BMI) and provide recommendations on healthy diet and physical activity.

4. Limit screen time – Parents can limit their children’s screen time by setting limits on phone, computer, and tablet use. Television time can also be limited.


Childhood obesity is a growing concern, and it is essential to address the contributing factors to prevent its onset. Encouraging physical activity, promoting healthy eating habits and engaging with health care providers are all effective strategies to prevent childhood obesity. Parents, caregivers, health care providers, and schools need to work together to ensure children maintain a healthy lifestyle that can reduce the chances of developing obesity and associated health problems.
