[ Objective ] To replot the gravidogram of fundal height, abdominal girth and body weight of nomal gravida in Foshan district. [ Methods ] The body weight distribution in 3 098 new-born babies born in our hospital was analysed retrospectively. The fundal height, abdominal girth and body weight of 6,866 normal gravida from the 24th to 42nd gestational week were measured prospectively. The normal range of the three factors and the alert region of fundal height to monitor fetal growth were determined. [Results] 87% of small for gestational age infants, 76% of large for gestational age infants were screened out by this gravidogram in clinical verification. Abnormal intrauterine development could be detected earlier through the monitor of gravidogram during pregnancy. [ Conclusions ] Gravidogram exhibits the superiority of briefness, high contrast and practicability in assessing the well-being of fetus. It might provide a reference for antipartum diagnosis in Foshan district.
