Childhood body weight is strongly influenced by genes according to new research published in the International Journal of Obesity. Previous research has shown that obesity runs in families, and twin studies suggest that this is largely due to genetic factors, with heritability estimates over 50%.
How does genetics affect childhood obesity?
Some children are at greater risk for obesity because of genetic factors. They have inherited genes from their parents that make their bodies gain weight easily. This would have been a very good trait hundreds of years ago, when food was hard to find and people were very active.
How much of childhood obesity is genetic?
New research suggests that about 35 to 40 percent of a child’s weight predisposition is inherited from mom and dad. In some cases of childhood obesity, the genetic impact may be as high as 55 to 60 percent.
Are parents the cause of childhood obesity?
Family history, psychological factors, and lifestyle all play a role in childhood obesity. Children whose parents or other family members are overweight or obese are more likely to follow suit. But the main cause of childhood obesity is a combination of eating too much and exercising too little.
What is the main cause of child obesity?
Lifestyle issues — too little activity and too many calories from food and drinks — are the main contributors to childhood obesity. But genetic and hormonal factors might play a role as well.
Are parents to blame for childhood obesity?
Pointing the finger of blame at parents for children’s weight gain may be unfair, research suggests. It has been thought that parents’ feeding patterns are a major factor in whether a child is under or overweight.
Can genetic obesity be cured?
Experts: Obesity Is Biologically ‘Stamped In,’ Diet and Exercise Won’t Cure It. New research into the biological mechanisms of obesity suggests eating less and exercising more aren’t enough for people with long-term weight problems.
How can we prevent childhood obesity?
The most important strategies for preventing obesity are healthy eating behaviors, regular physical activity, and reduced sedentary activity (such as watching television and videotapes, and playing computer games).
Is obesity caused by genetics or environment?
Obesity is determined by the genetics as well as obesogenic environment [4-5]. It was first studied in 1994 that Ob gene and leptin play an important role in determining the body weight of an individual .
Is obesity a genetic problem?
Science shows that genetics plays a role in obesity. Genes can directly cause obesity in specific disorders such as Bardet-Biedl syndrome and Prader-Willi syndrome. However genes do not always predict future health. Genes and behavior may both be needed for a person to be overweight.
Where is child obesity most common?
Among children 10 to 19, Nauru still appears to have the highest obesity rate at 31.7%, followed by the Cook Islands at 30.3%, Palau at 29.4%, Niue at 27.6%, Tuvalu at 25.3%, Tonga at 24.9% and the Marshall Islands at 24.4%, according to WHO data from 2016.
Who is most at risk for childhood obesity?
Children at risk of becoming overweight or obese include children who:
- have a lack of information about sound approaches to nutrition.
- have a lack of access, availability and affordability to healthy foods.
- have a genetic disease or hormone disorder such as Prader-Willi syndrome or Cushing’s syndrome.
Who is to blame for obesity?
Ninety-four percent of respondents said that they believed individuals were either primarily or somewhat to blame for the rise in obesity, with parents coming in second at 91 percent. Farmers and grocery stores were effectively off the hook.
How can obesity be prevented and treated?
- Exercise regularly. You need to get 150 to 300 minutes of moderate-intensity activity a week to prevent weight gain. …
- Follow a healthy-eating plan. …
- Know and avoid the food traps that cause you to eat. …
- Monitor your weight regularly. …
- Be consistent.
What can obesity lead to?
Consequences of Obesity
- All-causes of death (mortality)
- High blood pressure (hypertension)
- High LDL cholesterol, low HDL cholesterol, or high levels of triglycerides (Dyslipidemia)
- Type 2 diabetes.
- Coronary heart disease.
- Gallbladder disease.
- Osteoarthritis (a breakdown of cartilage and bone within a joint)
Is my child overweight?
One way to tell if your child is overweight is to calculate his or her body mass index (BMI). BMI is a measure of body weight relative to height. The BMI calculator uses a formula that produces a score often used to tell whether a person is underweight, a normal weight, overweight, or obese.
