Childhood obesity is a serious problem in society today. Children who are overweight face a higher risk of obesity in the future. From a medical perspective, obesity is an important factor in the development of conditions such as diabetes, high blood pressure, and heart disease, as well as disproportionate body shape. However, it can be prevented and treated when parents and teachers understand its causes, effects, and appropriate prevention methods.
Causes of Childhood Obesity
Several factors can make it difficult for children to manage their weight. The most important are genetic predisposition and environmental factors related to children's eating habits and physical activity.
Children whose parents have obesity are more likely to develop obesity themselves, both because of genetics and because family members often share eating and lifestyle habits. The environment also plays a significant role, including access to healthy food and enough space for children to run, play, or exercise.
Behavioral factors also influence children's eating habits and physical activity. These include consuming high-calorie foods, eating foods that are high in energy but low in nutritional value, such as packaged snacks, fried foods, and sugary drinks, spending long periods watching TV or gaming (read tips in How to Help a Child Who Is Glued to Screens), and not getting enough sleep. These habits often change depending on the child's environment.
Effects
Obesity has real effects on various aspects of children's lives. It can affect physical health and lead to long-term health problems as children enter adulthood.
- Effects on Physical Health
- Effects on Mental Health
- Effects on Learning
- Effects on Relationships with Parents and Classmates
| Area | Effects |
|---|---|
| Physical health | Diabetes, heart disease, high blood pressure |
| Mental health | Stress, depression |
| Learning | Children may tire easily, snore, or sleep poorly, which can affect their concentration in class. |
| Relationships with parents and classmates | Exclusion and teasing |
Reducing childhood obesity deserves attention to support children's health and quality of life, both now and in the future.
How to Tell If Your Child Has Obesity or Is Overweight
Children are still growing, so adult weight criteria cannot be used. Their weight needs to be assessed in relation to height, age, and sex using growth charts, such as those in Thailand's maternal and child health handbook (the pink book), or body mass index for age (BMI-for-age). A pediatrician can help assess this during a health checkup (find more information from the NHS).
Caution: Children should not be put on restrictive diets, made to skip meals, or given weight-loss medicines or products without professional guidance, because they still need energy and nutrients to grow. If you suspect your child is overweight, consult a pediatrician or dietitian to plan age-appropriate changes to their habits. For most children, the goal is to slow weight gain so it stays in balance with their increasing height.
Appropriate Feeding for Children
Providing appropriate, balanced meals is important for supporting good health and effectively preventing obesity.
1. Basic Recommendations:
Offer nutrient-rich foods such as vegetables, fruit, and appropriate amounts of protein from foods such as meat, beans, and grains (find ideas in 10 Meal Ideas for Children Aged 1 Year and Up). Choose foods that are low in fat and use less sugar when preparing meals for children.
2. Planning Balanced Meals:
Plan balanced meals that include foods from all five food groups, such as meat, rice, bread, and fruit, so children receive a variety of foods.
3. Observing and Monitoring Eating:
It is important to observe and monitor what children eat, including checking the ingredients in their meals, such as meat, vegetables, fruit, and other nutrients in the food they are eating.
Also watch for your child's cues that they are ready to stop eating, to assess how full they are and reduce the risk of overeating.
Long-Term Effects
Childhood obesity is an important issue with significant long-term effects. It can affect many aspects of a child's life, including:
- A higher risk of diabetes and high blood pressure
- A higher risk of mental health conditions such as depression and anxiety
- If obesity continues into adulthood, it increases the risk of heart disease, stroke, and certain cancers (Source: World Health Organization).
Obesity can also affect children's social and emotional well-being. Children with obesity are often teased, may feel bad about themselves, and may face more social difficulties than children without this problem.
| Effects | Ways to Reduce the Effects |
|---|---|
| Risk of diabetes and high blood pressure | A balanced approach to diet and exercise |
| Risk of mental health conditions | Recognizing and changing unhealthy habits |
| Risk of heart disease and certain cancers in adulthood | Comprehensive health care |
To help prevent these long-term effects, focus on improving the whole family's eating and physical activity habits under a pediatrician's guidance, rather than having children try to lose weight on their own (see guidance from HealthyChildren.org). Teachers, parents, and schools can also create an environment that encourages exercise and appropriate eating habits to support children's health.
Conclusion
To prevent childhood obesity, focus on appropriate, balanced meals and plan meals and activities tailored to children. These can include playing sports, walking or cycling in daily life, and reducing processed foods, sweets, and sugary drinks. Create an environment that supports children's health both at school and at home, for example through eating together as a family. You can also find more parenting tips here.
