The main purpose of the present study was to determine the relationship between salivary cortisol concentrations and self-report anxiety in 50 adolescent and 178 non-adolescent women during the last month of pregnancy. The subjects were randomly selected from a previous study involving women who attended antenatal care from September 1997 to August 2000 at 17 health services in Southeast Brazil. Salivary cortisol was measured with an enzyme immunoassay kit, and anxiety was assessed by the State-Trait Anxiety Inventories (STAI) of Spielberger. After saliva collection, the participants completed the STAI. Mean concentrations of cortisol for both pregnant adolescents (14.17 ± 6.78 nmol/l) and non-adolescents (13.81 ± 8.51 nmol/l) were similar (P = 0.89). Forty-three percent of the pregnant adolescents and 30.5% of the non-adolescents felt anxious at the time of being questioned (State Anxiety Inventory (SAI) scores >40; P = 0.06). Cortisol concentrations in adolescents were negatively related to the SAI scores (r = -0.39; P = 0.01) which assess a temporary condition of anxiety. There was a statistically significant difference in mean cortisol concentrations between adolescents with low (≤40) and high (>40) SAI scores (P = 0.03, t-test), but no differences for non-adolescents. The negative relationship between salivary cortisol concentrations and anxiety scores in adolescents may be due to puberty-related hormone differences during this period of life. Pregnant adolescents may possess unique biological or psychological characteristics compared to adults and non-pregnant adolescents. Thus, we need to know more about the hypothalamic-pituitary-adrenocortical axis of pregnant adolescents.

Background: Accurate estimation of fetal weight is of paramount importance in the management of labour and childbirth. In developing countries including India, estimation of fetal weight by clinical method is important as ultrasound is not available in all health care settings. In view of this, the present study was conducted to estimate the fetal weight assessed by clinical and ultrasound method and correlating with the birth weight.Methods: A cross-sectional study was conducted to estimate fetal weight clinically by using Johnson’s formula and sonographically based on Hadlock’s formula in the Department of Obstetrics and Gynecology in collaboration with Department of Radiodiagnosis, Regional Institute of Medical Sciences, Imphal from October 2016 to March 2018. The study consisted of 525 pregnant women between 37 to 40 weeks of gestation in whom delivery was anticipated within one week of fetal weight estimation by clinical and ultrasound method and correlating it with the baby’s birth weight measured immediately after delivery. Analysis was done using Chi-square and Student’s t-test and p-value of <0.05 was taken as significant.Results: Both methods showed positive correlation with birth weight but clinical method (r=0.925) had stronger correlation compared with ultrasound method (r=0.508).Conclusions: Fetal weight estimation using Johnson’s formula had stronger correlation with the birth weight than ultrasound method and hence, useful for developing countries and all health care workers may be sensitized about the method.
