Overview

Obesity is described as an excessive accumulation of fat that may be harmful to one's health. Children and teenagers are affected by the medical condition known as childhood obesity. A weight significantly higher than the average for a child's height and age is a symptom of childhood obesity.

Based on their Body Mass Index (BMI), a child or young person is categorized as overweight or obese. A child is considered obese if their body mass index-for-age (or BMI-for-age) percentile is greater than 95 percent. 

Obese children are more likely to develop health problems as adults if their condition is not addressed.


Why is Childhood Obesity a Problem?

Being overweight as a child raises concerns since it can often result in major health issues, including diabetes, hypertension, and high cholesterol. In addition to its medical consequences, childhood obesity has social and emotional effects.

The possible physical complications include:

  1. Type 2 Diabetes: The risk of type 2 diabetes increases by obesity and a sedentary lifestyle.

  2. High cholesterol and High blood pressure: Children may develop one or both of these illnesses due to a bad diet.

  3. Heart disease: Children who are obese are more likely to develop heart disease in the future due to excessive cholesterol and blood pressure. 

  4. Sleep Apnea and Asthma: Obese children are likelier to experience sleep disorders such as excessive snoring and sleep apnea. Extra weight around their necks can obstruct their airways.

  5. Osteoarthritis and Joint pain: Additional weight puts more pressure on the knees and hips. Hip, knee, and back pain are two common side effects of childhood obesity.

  6. Stroke

  7. Fatty liver

They might also struggle with social and emotional problems like:

  1. Anxiety

  2. Low self-esteem

  3. Depression

  4. Bullying


Symptoms and Causes  

Apart from excessive body weight, some prevalent signs and symptoms of childhood obesity are:

  1. Fatigue

  2. Increased sweating

  3. Sleep apnea and snoring

  4. Joint pains

  5. Shortness of breath

  6. Constipation

  7. Acid reflux

  8. Delayed puberty


What Causes of Childhood Obesity?

For growth and development, every child has to consume a certain amount of calories. However, if they consume more calories than they burn, their bodies retain the excess calories as fat. Many of the same factors that contribute to adult obesity also affect children. Family history, psychological issues, and lifestyle choices such as a bad diet and insufficient exercise are some causes of childhood obesity. 

Behaviour

Shared household behaviours, including dietary patterns and inactivity, may drive childhood obesity. A diet high in fat or sugar with few nutrients might cause children to gain weight quickly. The situation worsens by spending too much time doing sedentary activities like watching television or playing video games.

Genetics 

Children from a family of overweight people may be more inclined to gain weight. But a child's susceptibility to being overweight or obese is not necessarily determined by genes alone. Parents should encourage a healthy diet and way of life early in their children's development in households with a history of obesity.

Socioeconomics and Community

Some households only have limited resources and can't always acquire fresh meats, vegetables, and fruits. They might also not have access to their neighborhood parks, recreation centers, or an appropriate place to exercise.

Psychological problems may also cause childhood obesity. Overeating may be a coping mechanism for stress, anxiety, depression, or even to fight boredom.

Cultural factors

Childhood obesity is also influenced by exposure to commercials for high-sugar, high-fat foods, which comprise the majority of food marketing.

 

Diagnosis & Tests for Childhood obesity

It involves evaluating BMI, medical history, physical examination, and conducting blood tests to identify underlying factors.


How is Childhood Obesity Diagnosed?

When a child's BMI exceeds the 95th percentile of the sex-specific BMI-for-age growth charts, it can be medically determined that the child is obese. However, BMI alone can occasionally be deceptive because children grow at different rates.

A healthcare professional will often consider other factors while making a diagnosis, such as any health issues or symptoms associated with weight, a history of obesity in the family, level of physical activity, eating and sleep habits, and psychological or mental conditions. The diagnosis frequently also considers physical indicators like heart rate, blood pressure, and lab testing for thyroid function, hormone levels, cholesterol, and blood sugar.

The healthcare professional would develop a healthy weight loss strategy when a child has been diagnosed as obese. Healthy eating habits and the appropriate quantity of physical activity for the child are discussed and advised.


Management and Treatment for Childhood Obesity

The most effective treatment for childhood obesity depends on several factors, including the child's age, family history, and health. Consulting a doctor about the child's condition and available treatments is an ideal place to start. The many approaches used to treat childhood obesity include:

  1. Lifestyle changes, including physical activity and diet.

  2. Behavior modification

  3. Medication

  4. Surgery in rare cases


How to Help Children with Obesity?

Adopting some or all of these methods can assist a child in achieving and maintaining a healthy weight and treating obesity. 

  1. Adequate Exercise. Physical exercise is a vital component of weight management plans. This can take many forms, such as going for a stroll outside or engaging in sports. Playing hide-and-seek, jumping rope, having races, taking martial arts lessons, swimming, and biking are all excellent choices for physical activity for younger kids. 

  2. Dietary Changes. Prioritize eating nutritious meals that include fruits, vegetables, whole grains, seeds, nuts, and lean proteins. Reduce the consumption of processed foods, which can be high in calories, sugar, and fat.

  3. Reduce screen time. It might be challenging to control weight when the child spends a lot of time sitting down and playing video games, watching TV, texting, and browsing social media. Spending more time watching TV also translates into greater snacking time.


How to Teach Children Healthy Eating Habits?

If it is not advised by a physician or nutritionist for medical reasons, do not promote diets or restricted eating patterns for weight loss. Young adults require a healthy and balanced diet. Some useful tips to encourage and cultivate healthy eating are:

  1. Serve wholesome meals and snacks that are loaded with a variety of colourful fruits, veggies, whole grains, lean proteins, and healthy fats.

  2. Steer clear of sweet beverages like soda and sports drinks.

  3. Involve children in meal preparation.

  4. Incorporate snack time into daily routines.

  5. Avoid meals in front of screens.

  6. Be aware of what the kids eat outside the home as well. 


Prevention of Childhood Obesity

It includes promoting a healthy diet, regular physical activity, reducing sedentary behavior, and fostering a supportive environment for healthy habits.


How to Prevent Childhood Obesity?

The prevention of childhood obesity involves the support of family members and parents. The following are some of the best methods to address the unhealthy lifestyles that cause childhood obesity:

  1. Lead by example. Make eating well and exercising frequently a family affair.

  2. Be careful with sugary drinks. Fruit juice and sodas can fill children up and make it difficult for them to eat the foods that will keep them healthy.

  3. Healthy snacks should be readily available. Options such as fruits with low-fat yogurt and baby carrots with hummus can replace chips and chocolates.

  4. Children need to sleep sufficiently. According to certain studies, obesity risk may be increased by getting insufficient sleep.

  5. Teach techniques for reducing stress. Relaxing activities for kids include yoga, meditation, and calming art projects.


Conclusion

Childhood obesity is on the rise in several nations at worrisome rates. Children can adopt healthier eating habits and stay active with adequate guidance and support. Adults in their lives must take on this responsibility. Parents and other caregivers can impose a healthier lifestyle at home to prevent many obesity-related issues. Addressing the root causes of childhood obesity could result in a healthier society over time.
