تخمین وزن جنین با استفاده از اندازه ارتفاع رحم و دور شکم مادر

 Considering the hazards of macrosomia and low birth weight, the estimation of birth weight before delivery is of paramount importance. This study was performed to estimate the fetal weight on the base of mother fundal height and abdominal girth in women referred to Fathemieh hospital in Hamadan for delivery in 2000.           We conducted a descriptive study with 200 women (100 primipara and 100 multipara) who were selected through a random sampling. Inclusion criteria weresingle normal pregnancy, body weight less than 90 kg, empty bladder, negative station of presentation, intact amniotic bag. The variables included the uterine height and abdominal girth (in Cms). Estimated fetal weight obtained through multiplying the two values of above variables and    then comparing with the weight of newborn immediately after delivery.              The results showed that the mean of mother fundal height and abdominal girth were 33.92±2.85 cm and 97±6.2 cm respectively. The mean of estimated fetal weight and measured weight were 3088±382g and 3060 ±344g respectively. The coefficient of correlation between the estimated weight and measured weight was 0.61. Sensitivity and specifity of    this multiplication in detecting of fetuses larger than normal were 83.3% and 86.5% respectively and in detecting of fetuses smaller than normal were 48.4% and 96.2% respectively.               The uterine fundal height and abdominal girth can predict the neonatal birth weight.
