Obesity is a medical condition of excess body fat accumulated overtime, while overweight is a condition of excess body weight relatively to the height. According to the Body Mass Index(BMI), a BMI between 25 to 29.9 is considered over weight, while a BMI of over 30 is an indication of obesity. According to the statistic, 68% of American population are either overweight or obese.

You can calculate your BMI index BMI= weight (kg)/ height (m2)

The Studies of Risk of Obesity and First pregnancy


Women who are gaining excessive pregnancy weight gain in the first pregnancy are at increased risk of obesity. According to the study by the University of Pittsburgh, in a prospective cohort study of 3,422 non-obese, non-pregnant US women aged 14-22 years at baseline, adjusted Cox models were used to estimate the association among parity, inter-pregnancy intervals, and excessive pregnancyweight gain in the first pregnancy and the relative hazard rate (HR) of obesity, posted in PubMed, indicated that among women with the same parity and inter-pregnancy interval pattern, women with excessive pregnancy weight gain in the first pregnancy had an HR of obesity 2.41 times higher (95 % CI 1.81, 3.21; p < 0.001) than women without. Primiparous and nulliparous women had similarobesity risk unless the primiparous women had excessive pregnancy weight gain in the first pregnancy, then their risk of obesity was greater. Multiparous women with the same excessive pregnancy weight gain in the first pregnancy and at least one additional short inter-pregnancy interval had a significant risk of obesity after childbirth.
