Objective: To understand the pregnant women in Hefei during pregnancy weight gain, and its impact on pregnancy outcomes, help to guide pregnant women weight control during pregnancy. Methods: A total of 608 singleton pregnant women with normal pregnancy weight who were successfully delivered from January 2015 to December 2015 in Hefei Cancer Hospital of Chinese Academy of Sciences were collected and grouped according to R value during pregnancy. The age, pregnancy outcome and weight of newborn fetus Index, observe the trend of adverse pregnancy outcomes. Results: The pregnant women with normal weight before pregnancy had a significantly lower incidence of adverse pregnancy outcomes with a R value of 20 to 40 during pregnancy than those with a weight gain R of less than 20 or higher than 40 during pregnancy. Conclusion: The reasonable control of weight before pregnancy and the rate of weight gain during pregnancy can effectively reduce the risk of adverse pregnancy outcomes.
