Recent research showed that excessive weight gain during pregnancy can make children obese in teenage. Earlier studies have shown the relationship between excessive weight gain during pregnancy and a higher risk of obesity in childhood.

During recent study, researchers studied 11,994 children aged between 9 and 14 years. Around 1865 children were obese out of study subjects.

Researchers looked at data collected about mothers' pre-pregnancy weight and the weight gained during pregnancy of the study subjects.

Data analysis showed that when mothers exceeded the guidelines for pregnancy weight gain, their children's weight also was higher in majority of cases.

Researchers found that those whose mothers gained too much weight were 42 percent more likely to be obese by the time they were
9-to-14 years old as compared with their peers whose mothers followed the guidelines.

Researchers concluded that this study shows that excess pregnancy weight may affect fetal development and may make children more susceptible to excessive weight gain.

Result of the study support the already existing evidence that fetal environment may have a sustained effect on children's weight regulation.
