Abstract：Objective To establish percentile values for gestational age specific maternal weight and body mass index (BMI), and to examine the changes during pregnancy. Methods Eligible pregnant women attended the first prenatal visit (≤ 9 weeks gestation <14 weeks) during June 2009 to May 2011 were selected, and were follow-up. K-median-coefficient of variation method was used to smooth the percentile curves, and the changes of these two indicators during pregnancy were examined. Results Percentiles at P3, P10, P25, P50, P75, P90, and P93 of maternal weight and BMI were calculated. These percentile values increased with gestational age. The change curves of pregnancy weight and BMI were similar, characterized by ascending from 13th week, falling slowly at 28th week, and levelling off during 32th-38th week. The change curve of maternal weight rise slowly from 38th week. Conclusion Percentiles for gestational age specific maternal weight and BMI were obtained. These values can be used as a reference for the local antenatal care clinicians.
