A study on a few selected socio-biological determinants of birth weight was conducted at a rural project hospital in Haryana. Records of 2292 singleton live births over a period of two years (1985-1987) were analysed, by bivariate and multivariate methods. The mean birth weight of the infants was 2715 g (S.D. 453). Mean birth weight of male infants was 92 g more than female infants. Literacy levels of both parents, maternal age, parity, place of residence and antenatal care were found to have significant influence on the birthweight. Multiple regression showed that maternal age, maternal literacy and place of residence had minimal influence on the birth weight compared to other factors.

Background: The purpose of the study is to evaluate the role of uterine artery blood flow parameter measured by uterine artery two-dimensional (2D) power coloured doppler (PCD) ultrasound in predicting fertility outcomes in women undergoing ART treatment.Methods: It is prospective observational study. Total of 60 patients were included  of receiving infertility treatment in the age group20-40 years. 20 patients were selected for timed intercourse , 20 patients were selected for intrauterine insemination , 20 patients were selected for invitro fertilization. Transvaginalsonography will be done on the day of trigger by BHCG , UA PSV were measured,  and endometrial blood flow will be assessed. Predictivity of pregnancy rate  will be looked after by 3 ways: BHCG values  , UPT, Gestational sac  on USG.Results: In TI/IUI/IVF cycles the Doppler parameter PSV of uterine artery (23.08+/-3.39 vs 20.37-/+5.43) in pregnant vs non-pregnant group did not differ significantly. The mean PSV   of UA shows no significant difference women who were became pregnant during treatment and the women who were not became pregnant.Conclusions: With help of Doppler parameter imaging of women undergoing infertility it was found that UA PSV is non-significant to decide the prediction of pregnancy outcome.
