Nevertheless, not only women become pregnant overweight but also gain additional weight during gestation. A study found that obesity increased from 9.9% in 1990 to 16% in 2004 among pregnant women in the NorthEast of England [7]. An assessment performed among developing countries has ascertained that, in thirty-six of them, the proportion of overweight and obese women was higher than that of recommended weight among women, especially on urban population [8].
