Relationship of symphysio-fundal height and abdominal circumference to gestational age

ABSTRACT

Symphysio-fundal height (SF-height), abdominal, circumference (AC), anterior abdominal wall skinfold thickness were measured serially in (506) women with uncomplicated pregnancies in Mandalay General Hospital. A total of (2513) reading were made. The standard graphs of above measurements in relation of gestational age of fetus were drawn. The correlation coefficient (r) values were calculated. Both SF height and AC were increased as gestational age but the numerical values were not equivalent lto weeks of gestation. The engagement of head and anterior abdominal wall skinfold thickness did not change the relationship significantly. The normgravidogram. resulting from this study may be useful in detection of high risk pregnancies in antenatal clinics, although it cannot reflect the gestational age accurately. Further research work is necessary to detect reliability of this normgravidogram in screening of high risk cases.
