Background: The incidence of low birth weight babies continues to be high in India at about 30% in contrast to 5-7% in developed countries. Perinatal, neonatal and infant mortality as well as morbidity is associated with low birth weight (LBW) neonates of which, it is the Small for Gestational Age (SGA) neonates that are at increased risk. Henceforth, it becomes important to study the prevalence of SGA babies and to compare various anthropometric measurements among term neonates for assessing as to which of these could be taken as surrogate markers of small for gestational age babies.Methods: It was a cross sectional study conducted over a period of 2 years among 100 term neonates delivered in a private medical college in Puducherry, India.Results: The prevalence of low birth weight babies and small for gestational age was found to be 40% and 30% respectively. Using mid arm circumference as a predictor, the sensitivity, specificity, positive predictive value and negative predictive value of SGA was found to be 100%, 57.14%, 50% and 100% respectively. Using MAC/HC ratio as a predictor, the sensitivity, specificity, positive predictive value and negative predictive value was found to be 46.67%, 100%, 100% and 81.4% respectively.Conclusions: In predicting SGA babies, mid arm circumference has the highest sensitivity whereas MAC/HC ratio has the highest specificity followed by mid arm circumference. Present study concluded that mid arm circumference and ratio of MAC/HC are very helpful in identifying SGA neonates among term neonates.

OBJECTIVE: to assess the accuracy of the Capurro somatic and ultrasound methods, taking date of last menstruation as a reference point, for evaluating gestational age and anthropometric classification of term newborns. METHODS: a prevalence study was carried out involving 309 pregnant women and their term newborns, 92 of whom were small for gestational age and 217 appropriate sized for gestational age, at two public maternity hospitals in the Brazilian city of Salvador. The evaluation of the differences between the median gestational age according to the two methods was carried out using the non-parametric "Wilcoxon Signed-Rank Test." The accuracy of the methods for evaluating gestational age for the small for gestational age newborns was estimated by calculating the sensitivity, specificity, positive predictive value, negative predictive value and ROC (Receiver Operating Characteristic) curve. RESULTS: compared to ultrasound, the Capurro method overestimated the gestational age in newbornsof less than 39 weeks and underestimated it in older newborns. Ultrasound underestimated gestational agein newborns with more than 37 weeks. CONCLUSION: ultrasound was found to have greater sensitivity for prediction of small for age newborns (96.6%), while the Capurro method presented greater specificity (75.5%). The highest accuracy was obtained using ultrasound in the 41st gestational week (ROC=77.0%).

Gestational Age At Birth

Objective The objective of the study was to determine whether adding longitudinal measures of fundal height (FH) to the standard cross-sectional FH to trigger third trimester ultrasound estimated fetal weight (EFW) would improve small for gestational age (SGA) prediction. Study Design We developed a longitudinal FH calculator in a secondary analysis of a prospective cohort study of 1,939 nonobese pregnant women who underwent serial FH evaluations at 12 U.S. clinical sites. We evaluated cross-sectional FH measurement ≤ –3 cm at visit 3 (mean: 32.0 ± 1.6 weeks) versus the addition of longitudinal FH up to and including visit 3 to trigger an ultrasound to diagnose SGA defined as birthweight <10th percentile. If the FH cut points were not met, the SGA screen was classified as negative. If FH cut points were met and EFW was <10th percentile, the SGA screen was considered positive. If EFW was ≥10th percentile, the SGA screen was also considered negative. Sensitivity, specificity, and positive predictive value (PPV) and negative predictive value (NPV) were computed. Results In a comparison of methods, 5.8% of women were classified as at risk of SGA by both cross-sectional and longitudinal classification methods; cross-sectional FH identified an additional 4.0%, and longitudinal fundal height identified a separate, additional 4.5%.Using cross-sectional FH as an ultrasound trigger, EFW had a PPV and NPV for SGA of 69 and 92%, respectively. After adding longitudinal FH, PPV increased to 74%, whereas NPV of 92% remained unchanged; however, the number of women who underwent triggered EFW decreased from 9.7 to 5.7%. Conclusion An innovative approach for calculating longitudinal FH to the standard cross-sectional FH improved identification of SGA birthweight, while simultaneously reducing the number of triggered ultrasounds. As an essentially free-of-charge screening test, our novel method has potential to decrease costs as well as perinatal morbidity and mortality (through better prediction of SGA). Key Points

Background: Doppler provides assessment of uteroplacental and fetoplacental circulation during pregnancy. It is a sensitive tool in early detection of fetal compromise and allows needful intervention. Aims and Objective: To study the role of umbilical artery doppler in clinically suspected IUGR and its implication on neonatal outcome. Materials and Methods: A total of 104 singleton pregnancies with gestational age of more than 34 weeks who had clinical suspicion of IUGR were evaluated using obstetric ultrasound and doppler. Umbilical arteryvelocimetry with S/D >3 and RI >0.7 were considered abnormal. Newborns were classified as either small for gestational age (SGA) ie, IUGR or appropriate for gestational age (AGA). Neonatal outcome were classified as either normal or adverse events that included still birth, NICU admissions, perinatal asphyxia and/or neonatal death. Results: Out of 104 clinically suspected IUGR, 55 were born with small for gestational age. Among these SGA neonates, 45 subjects had abnormal umbilical artery S/D and 42 had abnormal RI. Abnormal umbilicalartery S/D ratio had a sensitivity of 81.8 %, specificity of 59.2 %, the positive predictive value of 69.2 % and negative predictive value of 74.4 %. Abnormal Umbilical artery RI had a sensitivity of 76.4 %, specificity of 69.4 %, positive predictive value of 73.7 % and negative predictive value of 72.3 % in diagnosing IUGR. Abnormal umbilical artery velocimetry was associated with increased morbidity and mortality in IUGR neonates. Conclusions: Umbilical artery doppler plays an important role in diagnosing IUGR and predicting neonatal outcome.

Background: A considerable evidence suggests that maternal inflammation dysregulation may play as a risk factor for both maternal and neonatal outcomes. Objective: The study’s objectives were designed to evaluate the correlation between serum C-reactive protein (CRP) levels, as an inflammation factor, preterm delivery, and small for gestational age (SGA) births. Materials and Methods: This prospective cohort study was conducted on 120 singleton pregnant women with gestational age less than 20 wk. Maternal CRP serum concentration was measured before 20 wk gestation. Patients were followed-up until the delivery and final outcomes of pregnancy were recorded in terms of preterm delivery and SGA births. Results: Serum CRP levels in participants with normal fetuses and SGA births were 4.09 ± 1.35 mg/l and 6.04 ± 3.29 mg/l, respectively (p = 0.19), while in cases of preterm delivery, it was 9.63 ± 5.78 mg/l (p < 0.001). By using receiver operating characteristic (ROC) curve, serum CRP levels (cut-off point 5.27 mg/l, area 0.836) had acceptable diagnostic accuracy value in distinguishing preterm delivery (sensitivity (75%), specificity (86.1%), positive predictive value (37.5%), negative predictive value (96.87%), accuracy (85%)) and serum CRP levels (cut-off point 6.67 mg/l, area 0.673) in distinguishing SGA births (sensitivity (50%), specificity (91.2%), positive predictive value (23.07%), and negative predictive value (97.19%), and accuracy (89.16 %)). Conclusion: Higher maternal serum CRP levels measured early in pregnancy may associate with higher risk of preterm delivery and SGA. Key words: C-reactive protein, Small for gestational age, Preterm birth.
