Question: Is childhood obesity genetic?

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?

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 [6].

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?
