A team from the University of Norwegian Science and Technology (NTNU) in Trondheim with 4,424 children and parents, followed them for 11 years.
Norwegian researchers argue that the child's way of life and habits would affect the child, although the influence of fathers would not have a great influence on them.
During this period, researchers reported changes in weight and physical activity among parents, as well as the weight of children by measuring body mass index (BMI).
After publishing in the BMJ Open magazine, the results showed that the weight of the mother and physical activity affected some of her children. The researchers found that weight loss of two to six kilograms was significantly associated with lower BMI in children.
Mothers who reduced their physical activity over the period tended to see their teenage BMI increase.
However, the researchers did not notice any relationship between losing weight of a father and BMI or physical activity.
"Parents have a great influence on their children's health and lifestyle. Behavior that leads to obesity can be easily transmitted from a parent to a child"explained Marit Næss.
Næss and colleagues think that the influence of the mother would be stronger because she often took responsibility for arranging meals and activities. They report that when a mother wants to lose weight, they often make minor changes to diet and lifestyle and the whole family. However, researchers did not incorporate this factor into their study.
The team did not find any connection between high weight loss in BMI parents of children and children, probably because this type of change is often associated with a particular diet or diet that is not followed by the whole family.
