Obesity is a condition where excess body fat has accumulated to the point where it negatively affects a person’s health or well-being. Obesity in children is known as Childhood obesity. Childhood obesity is defined as a Body Mass Index (BMI) greater than the 95th percentile on the child’s growth chart. It is becoming a larger problem than child malnutrition, as more and more children are being overweight or obese by the age of five.
The increase in the prevalence of childhood obesity can be attributed to several factors. The most obvious and easily measured factor is the increased availability of food. The introduction of the fast-food industry, the proliferation of the junk food industry, and the increased access to and affordability of highly processed foods in our society has contributed to the increasing prevalence of childhood obesity. The prevalence of obesity and overweight in children and young adults is higher than ever before in the history of the United States.
Causes of Obesity in children
Childhood obesity has become a global problem. It is a complex condition brought on by a range of factors.
- Unhealthy diet: A diet that is high in calories and low in nutrients can contribute to weight gain and obesity in children. This may include a diet that is high in processed and high-fat foods and low in fruits, vegetables, and other nutrient-rich foods. Also, when children eat more food than they need, the extra food is stored in the form of fat cells. This makes their weight increase.
- Lack of physical activity: Children who are inactive and do not engage in regular physical activity are at an increased risk of obesity.
- Environment: There is increasing evidence that the living environment of children can affect their physical activity behaviours and their risk of obesity. Several studies have found positive associations between active play, outdoor play and access to and use of parks and recreational areas with physical activity and a lower risk of obesity.
- Genetics: Polymorphisms in genes that control appetite and metabolism may predispose individuals to obesity when excessive calories are consumed. Some genetic conditions that can cause obesity in children include:
- Prader–Willi syndrome Bardet–Biedl syndrome
- MOMO syndrome
- Leptin receptor mutations
- Congenital leptin deficiency
- Melanocortin receptor mutations
- Family history: Obesity tends to run in families, suggesting that there may be a genetic component to the condition. Also, research has shown that children of two obese parents are more likely to be obese compared to children from two parents who have a normal weight.
- Medical conditions: Certain medical conditions, such as hypothyroidism and Cushing’s syndrome, can cause weight gain and obesity in children.
- Medications: Some medications, such as antidepressants and corticosteroids, can cause weight gain in children.
- Sleep patterns: Disruptions to sleep patterns, such as getting too little or too much sleep, can contribute to weight gain in children.
Treatment of obesity in children
In order to effectively address obesity in children, it’s important to consider the underlying causes and develop a treatment plan that addresses those factors. This may involve making changes to the child’s diet and physical activity habits, as well as addressing any underlying medical conditions or other factors that may be contributing to the condition. The best approach for a child will depend on their individual circumstances and needs.
Treating obesity in children typically involves a combination of diet, exercise, and behavioural therapy. In severe cases, medications or weight loss surgery may also be recommended.
- Diet: Making healthy changes to a child’s diet can help them lose weight and maintain a healthy weight over the long term. This may involve reducing the child’s intake of unhealthy foods, such as processed and high-fat foods, and increasing their intake of fruits, vegetables, and other nutrient-rich foods.
- Exercise: Encouraging children to engage in regular physical activity is an important part of any weight loss program. Aim for at least 60 minutes of moderate- to vigorous-intensity physical activity per day for children and adolescents.
- Behavioural therapy: Working with a healthcare professional or a mental health professional can help children identify and change behaviours that contribute to weight gain and obesity. This may involve learning new coping skills, setting achievable goals, and developing healthy habits.
- Medications: In some cases, medications may be recommended to help with weight loss in children. These medications work by reducing appetite, increasing feelings of fullness, or inhibiting the absorption of fat.
- Weight loss surgery: In severe cases of obesity in children, weight loss surgery may be recommended. There are several types of weight loss surgery, including gastric bypass surgery, laparoscopic banding, and gastric sleeve surgery. Weight loss surgery is typically reserved for children with a BMI of 40 or higher or those with a BMI of 35 or higher and a related health condition, such as diabetes or sleep apnoea.
Prevention of obesity in children
There are several strategies that can be used to prevent obesity in children. There are several effective strategies, including:
- Encourage a healthy diet: Help children make healthy food choices by providing them with a variety of nutrient-rich foods, such as fruits, vegetables, whole grains, and lean proteins. Avoid giving children sugary drinks and snacks and limit their intake of processed and high-fat foods.
- Promote physical activity: Encourage children to be physically active by providing them with opportunities for structured and unstructured physical activity. This can include activities such as sports, games, and other recreational activities.
- Limit screen time: Encourage children to spend less time in front of screens by setting limits on their use of TVs, computers, and other electronic devices.
- Model healthy behaviours: Children are more likely to adopt healthy behaviours if they see their parents and other adults modelling those behaviours. Make sure to set a good example by eating a healthy diet, being physically active, and limiting your own screen time.
- Support a healthy home environment: Create a home environment that supports healthy behaviours by providing healthy food options, encouraging physical activity, and limiting access to unhealthy foods and sedentary activities.
It’s important to note that preventing obesity in children requires a multifaceted approach that addresses a wide range of factors. Working with a healthcare professional or a nutritionist can help you develop a plan that is tailored to your child’s needs and circumstances.
