Parents must feel worried if their children too much weight. But the child obesity can be prevented by doing three healthy habits in the family.

Based on the results of a study there are three custom combinations can be associated with a lower risk of obesity in children, which made dinner together, make sure children get enough sleep and limit the number of children watching television.

The study involved 8550 children aged 4 years from several states in the United States. Found children who eat dinner with families at least five times a week, get hours of sleep at least 10 hours and watch television less than 2 hours a day, have a risk of 40 per cent less for a child obesity than children who do not do those three things.

It is estimated that only 1 in 7 children who apply these 3 are obese, compared with 1 in 4 children who did not apply this experience obesity. The results of this study have been published in the journal Pediatrics.

If the family can not do those three things, there’s nothing wrong to apply one of them. Because the study also found a decrease in the risk of obesity by 25 percent if doing one of these routines.

“We found an independent effect of each of these activities. But doing all three will give better results, because it can reduce the risk of obesity is more”.

By doing dinner with the family, so parents can monitor what foods consumed by children. If your child getting enough sleep will prevent children consume snacks at night and reduce television viewing would make the child do physical activities more.

No harm in applying this third in a family activity that children do not become obese and avoid the risk factors for several chronic diseases later on.

This statement comes from the findings of a study conducted by researchers at University College London, who assessed the body mass index (BMI) and waist circumference in a sample of 5092 twin pairs aged 8 to 11 years born between 1994 and 1996.

Twin studies are performed to differentiate between the risks of genetic nature imposed by environmental factors such as diet or socioeconomic status.

Thus, if the genetic variations have considerable influence on obesity risk, or monozygotic twins with identical genes, should have an increased risk of obesity than Fraternal or dizygotic twins with different genes, living in the same environment.

study showed that identical twins had BMI and waist circumferences of more similar than Fraternal twins even though each pair of twins lived in the same house.

Further analysis predicted that the inherent risk to obesity is genetically determined in approximately 77% while shared environmental factors weighed 10% and 14% unshared.

These results confirm other studies which suggested a contribution of genes on the risk of obesity of between 55 and 85%.

The authors acknowledge that the environments that promote obesity pose a major risk factor but, nevertheless, genetic predisposition is the most important reason that some children are obese while others do not.

Also recommend that diet, nutrition and physical activity of children is optimized to ensure that those who are genetically predisposed to obesity do not accumulate excess weight
