Overview
Childhood obesity is a medical condition that affects children.Overweight and obesity are defined by the World Health Organization (WHO) as "abnormal or excessive fat accumulation that may impair health"[1] Childhood Obesity is a Body Mass Index (BMI) at or above the 95th percentile for children of the same gender and age.[2] Childhood and adolescent obesity is an epidemic in the United States.[3] About 13.7 million (18.5 %) of American children and adolescents are currently considered obese[4]
Historical Perspective
Classification
Pathophysiology
Causes
Childhood obesity maybe cause by poor eating habits, lack of physical activity, genetic causes, an underlying medical condition or medications.
Lifestyle and Dietary Intake
Children and adolescents are consuming low nutrient high-calorie foods and beverages at home, school and other places. They are consuming more fast food which is low in nutrients and high in calories, fat and sodium. CDC reports that children and adolescents in the U.S. consumed an average of 13.8% of their daily calories from fast food during 2015-2018. [5] In addition, they are consuming large amounts of sugar-sweetened beverages which has been directly associates with obesity in multiple reviews.[6] [7] Physical inactivity, excess use of screen time and inadequate sleep also contribute to the obesity epidemic.[8] [9]
Environmental Factors
Eating habits of the child are also affected by demographics, lunch policies at schools and work demands on parents.[10]
Psychological factors
These factors influence a child's eating habits and many children eat in response to stress and or negative emotions such as boredom, anger, sadness, anxiety or depression.
Hereditary
Often, a child whose parents are overweight or obese will also be overweight or obese. Although this is often caused by shared unhealthy eating habits in the household, it has been suggested that there may be a genetic (inherited) predisposition toward being obese, although this is as yet unproven and research is ongoing. Many children become slightly overweight because of their body's growth pattern (example: being taller than average at childhood). Some pediatricians may still classify this as childhood obesity.Template:Facts Recent studies have shown that while there is evidence of in vitro influences on food choice, perhaps the largest influence can occur during the toddler years.[11] Indeed, recent studies have shown that parents influence an estimated 72% of what and how much their children eat on a daily basis. [12]
Underlying Medical Causes of Obesity
Conditions such as hypothyroidism, Cushing's syndrome, depression and certain neurological problems can lead to obesity or a tendency to gain weight in a child. Also, drugs such as steroids and some antidepressants may lead to obesity or a tendency to gain weight in a child.
Complications
Without a change in diet or exercise patterns, childhood obesity can lead to medical conditions including Type 2 diabetes, high blood pressure, high cholesterol, heart disease, asthma, sleep apnea, fatty liver disease, gall stones, glucose intolerance, insulin resistance and other disorders.[13] [10] Studies have shown that obese children are more likely to grow up to be obese adults.[14] Obese children often suffer from teasing amongst their peers.[15][16] Some are even harassed or discriminated against by their own family.[17] Stereotypes abound and may lead to low self esteem and depression.[18]
