Weight gain ” Ideal ” during pregnancy depends on the initial weight women : it is thus 5 9 kg for a body mass index greater than 30, 7 11 kg for a BMI between 25 and 29, 11 to 16 kg if BMI is between 18.5 and 25 and finally 13 18 kg if BMI is less than 18.5 kg.
Through an extensive survey conducted in Northern California, the researchers analyzed data from 4,145 women who gave birth between 2007 and 2009, and followed the medical records of children between the ages of 2 and 5 years.
Their findings, published in the American Journal of Obstetrics and Gynecology, shows that 20.4 % of children whose mothers had taken more than the recommended weight during pregnancy are obese or overweight.
Nearly 19.5 % of those born to mothers who took little or not enough weight suffered from similar disorders.
This figure rose to 14.5% for women whose weight gain was “Normal” or similar to the recommendations made.
Researchers have noted that women whose BMI was normal before pregnancy but who took more than the recommended weight had an increased risk of 80% to the world a child who would later become obese or overweight.
” This association is independent of genetic factors,” recounts Dr. Monique M.
Hedderson, co- author of the study.
” Taking too much or too little weight can affect long term ” the mechanisms that control the regulation of energy balance and metabolism, such as appetite and energy expenditure, Sneha says Sridhar, lead author of this study.
Do everything possible to stay slim during pregnancy is not necessarily a good idea, no better than eating for two!
