Objective: To develop a chart for risk of small-for-gestational-age (SGA) at birth depending on deviations in symphysis-fundus (SF) height values for gestational age during pregnancy weeks 24-42.Design: Registry-based population cohort study.Setting: Antenatal clinics, Västra Götaland County, Sweden, 2005-2010.Population: The study included 42 018 women with ultrasound-dated singleton pregnancies who delivered at Sahlgrenska University Hospital. Data (including 282 713 SF height measurements) were extracted from the hospital's computerised obstetric database.Methods: Linear and binary regression analyses were used to derive prediction models with deviations in birthweight (BW) and SF height by gestational age as dependent and independent variables, respectively. Receiver operating characteristic curves were generated to evaluate the predictive value of the model in detecting SGA.Main Outcome Measures: Birthweight and small-for-gestational-age.Results: Symphysis-fundus height accounted for 3% of individual BW variance at 24 weeks, increasing gradually to 20% at 40 weeks. Maternal factors explained an additional 10 percentage points of BW variance. Receiver operating characteristic curves confirmed that SF height was a stronger SGA predictor in late than in early pregnancy. Using an SGA relative risk cut-off limit of ≥2-fold, the overall sensitivity was 50% and the overall specificity 80%. Only the most recent SF measurement was useful in predicting BW deviation; previous measurements added nothing to the predictive value.Conclusions: The ability of SF measurements to detect SGA status at birth increases with gestational age. Only the most recent SF measurement has predictive value; a static or falling pattern of SF values did not increase SGA likelihood.Tweetable Abstract: New SF curves predict SGA best in late pregnancy; only the most recent SF measurement has predictive value.

Background: We aimed to examine the inter-reliability and agreement among midwives when assessing the fetal heart rate (FHR) using the handheld Doppler. The primary aim was to measure the reliability and agreement of FHR baseline (baseline) as beats per minute (bpm). The secondary aims were to measure fluctuations from the baseline, defined as increases and decreases, and classifications (normal or abnormal) of FHR soundtracks. This is the first interrater reliability and agreement study on intermittent auscultation (IA) to our knowledge., Methods: The participant population consisted of 154 women in labor, from a mixed-risk population and admitted to hospital for intrapartum care. The rater population were 16 midwives from various maternity care settings in Norway. A total of 154 soundtracks were recorded with a handheld Doppler device, and the 16 raters assessed 1-min soundtracks once, through an online survey (Nettskjema). They assessed the baseline, FHR increase or decrease, and the FHR classification. The primary outcome, baseline, was measured with intraclass correlation coefficient (ICC). The secondary outcomes were measured with kappa and proportion of agreement., Results: The interrater reliability for the baseline (bpm) was ICC(A,1) 0.74 (95% CI 0.69-0.78). On average, an absolute difference of 7.9 bpm (95% CI 7.3-8.5 bpm) was observed between pairs of raters., Conclusion: Our results demonstrate an acceptable level of reliability and agreement in assessing the baseline using a handheld Doppler., (© 2024 The Author(s).

Objectives: This systematic scoping review was conducted to 1) identify and describe labor curves that illustrate cervical dilatation over time; 2) map any evidence for, as well as outcomes used to evaluate the accuracy and effectiveness of the curves; and 3) identify areas in research that require further investigation., Methods: A three-step systematic literature search was conducted for publications up to May 2023. We searched the Medline, Maternity & Infant Care, Embase, Cochrane Library, Epistemonikos, CINAHL, Scopus, and African Index Medicus databases for studies describing labor curves, assessing their effectiveness in improving birth outcomes, or assessing their accuracy as screening or diagnostic tools. Original research articles and systematic reviews were included. We excluded studies investigating adverse birth outcomes retrospectively, and those investigating the effect of analgesia-related interventions on labor progression. Study eligibility was assessed, and data were extracted from included studies using a piloted charting form. The findings are presented according to descriptive summaries created for the included studies., Results and Implications for Research: Of 26,073 potentially eligible studies, 108 studies were included. Seventy-three studies described labor curves, of which ten of the thirteen largest were based mainly on the United States Consortium on Safe Labor cohort. Labor curve endpoints were 10 cm cervical dilatation in 69 studies and vaginal birth in 4 studies. Labor curve accuracy was assessed in 26 studies, of which all 15 published after 1986 were from low- and middle-income countries. Recent studies of labor curve accuracy in high-income countries are lacking. The effectiveness of labor curves was assessed in 13 studies, which failed to prove the superiority of any curve. Patient-reported health and well-being is an underrepresented outcome in evaluations of labor curves. The usefulness of labor curves is still a matter of debate, as studies have failed to prove their accuracy or effectiveness., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Huurnink et al.

Introduction: A pregnancy can be evaluated as high-risk for the woman and/or the fetus based on medical history and on previous or ongoing pregnancy characteristics. Monitoring high-risk pregnancies is crucial for early detection of alarming features, enabling timely intervention to ensure optimal maternal and fetal health outcomes. Home-based telemonitoring (HBTM) is a marginally exploited opportunity in antenatal care. The aim of this study was to illuminate healthcare providers' and users' expectations and views about HBTM of maternal and fetal health in high-risk pregnancies before implementation., Material and Methods: To address diverse perspectives regarding HBTM of high-risk pregnancies, four different groups of experienced healthcare providers or users were interviewed (n = 21). Focus group interviews were conducted separately with midwives, obstetricians, and women who had previously experienced stillbirth. Six individual interviews were conducted with hospitalized women with ongoing high-risk pregnancies, representing potential candidates for HBTM. None of the participants had any previous experience with HBTM of pregnancies. The study is embedded in a social constructivist research paradigm. Interviews were analyzed using a thematic approach., Results: The participants acknowledged the benefits and potentials of more active roles for both care recipients and providers in HBTM. Concerns were clearly addressed and articulated in the following themes: eligibility and ability of women, availability of midwives and obstetricians, empowerment and patient safety, and shared responsibility. All groups problematized issues crucial to maintaining a sense of safety for care recipients, and healthcare providers also addressed issues related to maintaining a sense of safety also for the care providers. Conditions for HBTM were understood in terms of optimal personalized training, individual assessment of eligibility, and empowerment of an active patient role. These conditions were linked to the importance of competent and experienced midwives and obstetricians operating the monitoring, as well as the availability and continuity of care provision. Maintenance of safety in HBTM in high-risk pregnancies was crucial, particularly so in situations involving emerging acute health issues., Conclusions: HBTM requires new, proactive roles among midwives, obstetricians, and monitored women, introducing a fine-tuned balance between personalized and standardized care to provide safe, optimal monitoring of high-risk pregnancies., (© 2023 The Authors.

Background: Globally, gestational diabetes mellitus complicates 1 in 6 pregnancies and increases future risk of type 2 diabetes and cardiovascular disease in the affected women. There is a lack of consensus on the optimal follow-up of these women. eHealth is emerging as a health care tool, but its practical utility and advantages over standard care in the follow-up after pregnancy complications remains to be determined. Our aim was to systematically review the existing literature on cardiovascular follow-up after gestational diabetes, the utility of eHealth technology for this purpose, and to identify research gaps., Methods: We performed a systematic scoping review following a published protocol and the Joanna Briggs methodology for studies up until May 2022. Four databases were searched: Ovid MEDLINE, Embase, Maternity and Infant Care, and Cochrane Database of Systematic Reviews. Primary research articles and systematic reviews were included in the final analyses. Two reviewers independently screened abstracts and performed full text assessment. Data was extracted using a data charting form. In all stages of the process, if consensus was not reached, a third reviewer was consulted. The findings from the data charting process provided the basis for summarizing the findings from the included studies., Results: The search of the databases generated 2772 hits. After removing duplicates and manually adding a total of 19 studies, reviews, and guidelines, a total of 2769 titles and abstracts were screened, and 97 papers underwent full-text review. In the final analyses, 15 articles and 12 systematic reviews were included, whereas guidelines are presented as supplementary material. No studies were identified that examined follow-up regarding long-term overall cardiovascular risk after gestational diabetes. Various lifestyle interventions were tested for individual cardiovascular risk factors, with diverging effects. eHealth technologies were found acceptable by participants but had no consistent, statistically significant effect on relevant health outcomes., Conclusions: This scoping review of the existing literature revealed neither an established systematic cardiovascular follow-up strategy for women after gestational diabetes nor evidence that eHealth technologies are superior to conventional follow-up. Further research into the utility of eHealth in cardiovascular follow-up after complicated pregnancies should include longer-term follow-up and core cardiovascular outcomes., Systematic Review Registration: The protocol for this scoping review was published at Open Science Framework (osf.io/p5hw6)., (© 2023.

Background: Umbilical cord blood acid-base sampling is routinely performed at many hospitals. Recent studies have questioned this practice and the association of acidosis with cerebral palsy., Objective: To investigate the associations between the results of umbilical cord blood acid-base analysis at birth and long-term neurodevelopmental outcomes and mortality in children., Search Strategy: We searched six databases using the search strategy: umbilical cord AND outcomes., Selection Criteria: Randomised controlled trials, cohorts and case-control studies from high-income countries that investigated the association between umbilical cord blood analysis and neurodevelopmental outcomes and mortality from 1 year after birth in children born at term., Data Collection and Analysis: We critically assessed the included studies, extracted data and conducted meta-analyses comparing adverse outcomes between children with and without acidosis, and the mean proportions of adverse outcomes. The certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations approach., Main Results: We have very low confidence in the following findings: acidosis was associated with higher cognitive development scores compared with non-acidosis (mean difference 5.18, 95% CI 0.84-9.52; n = two studies). Children with acidosis also showed a tendency towards higher risk of death (relative risk [RR] 5.72, 95% CI 0.90-36.27; n = four studies) and CP (RR 3.40, 95% CI 0.86-13.39; n = four studies), although this was not statistically significant. The proportion of children with CP was 2.39/1000 across the studies, assessed as high certainty evidence., Conclusion: Due to low certainty of evidence, the associations between umbilical cord blood gas analysis at delivery and long-term neurodevelopmental outcomes in children remains unclear., (© 2023 John Wiley & Sons Ltd.)

Introduction: Fetal heart rate (FHR) monitoring is routine in intrapartum care worldwide and one of the most common obstetrical procedures. Intrapartum FHR monitoring helps assess fetal wellbeing and interpretation of the FHR help form decisions for clinical management and intervention. It relies on the observers' subjective assessments, with variation in interpretations leading to variations in intrapartum care. The purpose of this systematic review was to summarize and evaluate extant inter- and intrarater reliability research on the human interpretation of intrapartum FHR monitoring., Material and Methods: We searched for the terms "fetal heart rate monitoring," "interpretation agreement" and related concepts on Embase, Medline, Maternity and Infant Care Database and CINAHL. The last search was made on January 31, 2022. The protocol for the study was prospectively registered in PROSPERO (CRD42021260937). Studies that assess inter- and intrarater reliability and agreement of health professionals' intrapartum FHR monitoring were included and studies including other assessment of fetal wellbeing excluded. We extracted data in reviewer pairs using quality appraisal tool for studies of diagnostic reliability (QAREL) forms. The data retrieved from the studies are presented as narrative synthesis and in additional tables., Results: Forty-nine articles concerning continuous FHR monitoring were included in the study. For interrater reliability and agreement, in total 577 raters assessed 6315 CTG tracings. There was considerable heterogeneity in quality and measures across the included articles. We found higher reliability and agreement for the basic FHR features than for overall classification and higher agreement for intrarater reliability and agreement than for their interrater counterparts., Conclusions: There is great variation in reliability and agreement measures for continuous intrapartum FHR monitoring, implying that intrapartum CTG should be used with caution for clinical decision making given its questionable reliability. We found few high-quality studies and noted methodological concerns in the studies. We recommend a more standardized approach to future reliability studies on FHR monitoring., (© 2023 The Authors.

Introduction: International guidelines recommend that external cephalic version (ECV) be offered to all women with single fetuses in breech presentation at term. In Norway, ECV is not offered routinely; the national clinical guidelines advice that birth units capable of offering ECV for breech pregnancies make their own practice decisions. This study was performed to determine the extent to which Norwegian birth units offer ECV to pregnant women with fetuses in breech presentations at term, and to identify factors that might influence the use of ECV., Material and Methods: A survey of all 39 obstetric birth units providing ECV in Norway was conducted using a self-reporting questionnaire about ECV availability, attitudes, clinical procedures, perceived competence, and outcome expectations., Results: Chief obstetricians from all birth units responded. Twenty-six (67%) respondents reported that their units offered ECV for breech presentation at term to a large degree. Thirty-one (80%) respondents reported a large degree of competence in performing ECV. Thirty-three (85%) units followed local ECV procedures. Nineteen (49%) units provided standardized information about the procedure to pregnant women. The respondents had different views about who should be offered ECV, and varying knowledge about ECV outcomes., Conclusions: The majority of Norwegian birth units offer ECV to pregnant women with fetuses in breech position to a large extent. However, the survey results reveal challenges related to ECV information provision to pregnant women, determination of women's eligibility for ECV attempts, and familiarity and agreement with the knowledge base regarding ECV., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 The Authors.

Objective: In most high-income countries, the cardiotocography and handheld Doppler device have replaced the Pinard stethoscope for intrapartum foetal monitoring. As a result, the skills required to use the Pinard are rapidly disappearing from midwifery. The aim of this study was thus to illuminate the knowledge before it is lost, by exploring the practice, skills and experience of Norwegian midwives familiar with the Pinard for intrapartum foetal monitoring. We included midwives who still regularly use the Pinard in their current practice in a variety of birth settings, and those who used the Pinard in the era prior to the introduction of the CTG., Design: This study followed a qualitative descriptive design based on mainly focus group interviews, but also including one individual interview. The interviews explored the participants` perspective on their practice, skills and experience regarding the use of the Pinard for intrapartum foetal monitoring. Reflexive thematic analysis captured common patterns across the data, and contextualism was used as research paradigm., Setting and Participants: In total, 21 midwives with experience using the Pinard for intrapartum foetal monitoring were interviewed. The midwives were either retired and had experience using the Pinard from before the CTG became widespread; worked in an alongside midwifery unit that only oversees low-risk births; or worked in an obstetric unit in a university hospital with an active policy of using the Pinard for intrapartum foetal monitoring., Findings: The analysis resulted in four main themes: "Practice and experience with the Pinard are related to context", "Skills with the Pinard come with work experience", "The Pinard reveals certain characteristics of foetal sound" and "Midwives` experience with the benefits of using the Pinard". The midwives considered the context for using the Pinard for intrapartum foetal monitoring relevant. The e availability of technology and applicable situations for using the Pinard influenced how and when they use the Pinard. They further underpinned training and work experience as important for feeling secure when using the Pinard, and this experience made them recognize normal and abnormal foetal sounds. Defining and characterizing these sounds appeared difficult for the midwives, however, and they hesitated and imitated the sound. The midwives felt that the Pinard is beneficial for both the labouring woman and the midwife, as the Pinard's features bring them closer to the labouring woman and help calm the birth suite. They also felt that the Pinard adds further information about the birth and birth process, such as foetal lie, rotation and descent., Keyconclusions: Norwegian midwives' practice, and experiences in using the Pinard for intrapartum foetal monitoring are connected to context as technological development and applicable situations. The midwives explained that knowledge obtained through experience gives them skills to differentiate between normal and abnormal foetal sound characteristics, though they found it difficult to define the characteristics themselves. Using the Pinard stethoscope during birth calms the birth suite and brings the midwife closer to the labouring woman., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022.

Introduction: In 2010, the Norwegian Directorate of Health introduced the guideline 'Safe maternity services - quality standards for maternal care'. These standards include adequate staffing with health care personnel for birth units to ensure responsible monitoring and treatment. Birth units are to follow the professional recommendation that every woman has a midwife present during established labor. This study presents data from birth units on compliance with the national recommendation for one-to-one care during labor., Methods: A web-based questionnaire was emailed to chief midwives of all birth units in Norway (n=48) in May 2018. The questionnaire contained a total of nine multiple-choice, scaled-response-format, and free-text questions., Results: The questionnaire response rate was 100%. All birth units reported that they offered women one-to-one care during labor to a large extent. Sixty-five per cent of the birth units had procedures to ensure that midwives were present during established labor. Deviations from the recommendation were recorded in one-fourth of birth units. Thirty-eight per cent of respondents reported that staff training had been provided; 56% of birth units stated that the recommendation led to an increased presence of midwives during labor. Financial constraints (35%) and difficulty of compliance (27%) were cited as obstacles to meeting the recommendation for one-to-one care during labor., Conclusions: The majority of birth units reported that they follow the recommendation for one-to-one care during established labor, but compliance with this recommendation in practice remains unclear. Areas of improvement relate to routines describing the presence of midwives during labor, registration of deviations, and staff training in one-to-one care., Competing Interests: The authors have completed and submitted the ICMJE Form for Disclosure of Potential Conflicts of Interest and none was reported., (© 2019 Bjerga B.G.)

Background: Intermittent auscultation (IA) is the technique of listening to and counting the fetal heart rate (FHR) for short periods during active labour and continuous cardiotocography (CTC) implies FHR monitoring for longer periods. Although the evidence suggests that IA is the best way to monitor healthy women at low risk of complications, there is no scientific evidence for the ideal device, timing, frequency and duration for IA. We aimed to give an overview of the field, identify and describe methods and practices for performing IA, map the evidence and accuracy for different methods of IA, and identify research gaps., Methods: We conducted a systematic scoping review following the Joanna Briggs methodology. Medline, EMBASE, Cinahl, Maternity & Infant Care, Cochrane Library, SveMed+, Web of Science, Scopus, Lilacs and African Journals Online were searched for publications up to January 2019. We did hand searches in relevant articles and databases. Studies from all countries, international guidelines and national guidelines from Denmark, United Kingdom, United States, New Zealand, Australia, The Netherlands, Sweden, Denmark, and Norway were included. We did quality assessment of the guidelines according to the AGREEMENT tool. We performed a meta-analysis assessing the effects of IA with a Doppler device vs. Pinard device using methods described in The Cochrane Handbook, and we performed an overall assessment of the summary of evidence using the GRADE approach., Results: The searches generated 6408 hits of which 26 studies and 11 guidelines were included in the review. The studies described slightly different techniques for performing IA, and some did not provide detailed descriptions. Few of the studies provided details of normal and abnormal IA findings. All 11 guidelines recommended IA for low risk women, although they had slightly different recommendations on the frequency, timing, and duration for IA, and the FHR characteristics that should be observed. Four of the included studies, comprising 8436 women and their babies, were randomised controlled trials that evaluated the effect of IA with a Doppler device vs. a Pinard device. Abnormal FHRs were detected more often using the Doppler device than in those using the Pinard device (risk ratio 1.77; 95% confidence interval 1.29-2.43). There were no significant differences in any of the other maternal or neonatal outcomes. Four studies assessed the accuracy of IA findings. Normal FHR was easiest to identify correctly, whereas identifying periodic FHR patterns such as decelerations and saltatory patterns were more difficult., Conclusion: Although IA is the recommended method, no trials have been published that evaluate protocols on how to perform it. Nor has any study assessed interrater agreements regarding interpretations of IA findings, and few have assessed to what degree clinicians can describe FHR patterns detected by IA. We found no evidence to recommend Doppler device instead of the Pinard for IA, or vice versa., Competing Interests: The authors have declared that no competing interests exist.

Introduction: This study describes clinical routines for intrapartum fetal monitoring in Norway and compliance with national clinical recommendations., Material and Methods: A national survey of all (n = 48) birth units in Norway, using a self-reporting questionnaire about fetal monitoring methods and devices available in the birth units, admission cardiotocography (CTG) use, intrapartum fetal monitoring methods for women with and without risk factors, the availability of fetal scalp blood sampling facilities, and umbilical cord blood sampling routines., Results: All birth units responded. They all had access to Pinard stethoscopes, hand-held Doppler devices, and CTG. Half of the units used ST waveform analysis (STAN) as an adjunct to CTG. Furthermore, 23 of 48 units analyzed fetal blood samples and 43 of 48 umbilical cord blood gas samples. In 11 units, admission CTG was routinely offered to all women. No units used continuous CTG during labor in low-risk women. However, three units routinely used intermittent CTG during the first stage of labor. Three units used CTG without having access to fetal blood samples or STAN., Conclusions: Our findings indicate some deviations from clinical recommendations in the use of intrapartum fetal monitoring in Norway. Three units used intermittent CTG for women without risk factors. Almost one in four units routinely used admission CTG, despite national clinical recommendations. The lack of access to fetal blood samples or STAN in units using CTG is of concern., (© 2018 Nordic Federation of Societies of Obstetrics and Gynecology.)

Bakgrunn: I Norge utføres abort kun i offentlige sykehus. I 2010 besluttet Helse- og omsorgsdepartementet å iverksette et toårig prøveprosjekt som ga avtalespesialister i fødselshjelp og kvinnesykdommer adgang til å tilby medikamentell abort før utgangen av 9. svangerskapsuke. Prøveprosjektet ble igangsatt 1.3.2015 og varte til 31.3.2017. I denne artikkelen presenterer vi de første erfaringene, herunder hvordan behandlingstilbudet ble mottatt av kvinnene., Materiale Og Metode: Gravide med en svangerskapsvarighet < 63 dager ultrasonografisk vurdert, som oppsøkte avtalespesialist for medikamentell abort, ble fortløpende inkludert i prosjektet (n = 476). Kvinnene inntok 200 mg mifepriston peroralt på legekontoret, 36-48 timer senere satte de selv 800 µg misoprostol vaginalt hjemme. Informasjon ble innhentet ved spørreskjema på den første konsultasjonen, under aborten og ved etterkontrollen 2-4 uker etter aborten., Resultater: Under aborten rapporterte 66 % (296/450) moderat eller sterk smerte og 79 % (358/451) moderat eller sterk blødning. De fleste opplevde det som trygt å være hjemme. 96 % (390/406) ville valgt medikamentell abort hos avtalespesialist ved en eventuell senere abort, og 97 % (392/405) ville anbefalt behandlingstilbudet til andre i samme situasjon., Fortolkning: Kvinnene i studien opplevde abortbehandling hos avtalespesialist som trygt. Tilbudet gir større valgfrihet til gravide som ønsker abort, og pasientene er tilfredse.

Background: The Directorate of Health’s national guide Et trygt fødetilbud – kvalitetskrav til fødselsomsorgen [A safe maternity service – requirements regarding the quality of maternity care] was published in December 2010 and was intended to provide a basis for an improved and more predictable maternity service. This article presents data from the maternity institutions on compliance with the quality requirements, including information on selection, fetal monitoring, organisation, staffing and competencies., Material and Method: The information was acquired with the aid of an electronic questionnaire in the period January–May 2015. The form was sent by e-mail to the medical officer in charge at all maternity units in Norway as at 1 January 2015 (n=47)., Results: There was a 100 % response to the questionnaire. The criteria for selecting where pregnant women should give birth were stated to be in conformity with the quality requirements. Some maternity institutions failed to describe the areas of responsibilities of doctors and midwives (38.5 % and 15.4 %, respectively). Few institutions recorded whether the midwife was present with the patient during the active phase. Half of the maternity departments (level 2 birth units) reported unfilled doctors’ posts, and a third of the university hospitals/central hospitals (level 1 birth units) reported a severe shortage of locum midwives. Half of the level 2 birth units believed that the quality requirements had resulted in improved training, but reported only a limited degree of interdisciplinary or mandatory instruction., Interpretation: The study reveals that there are several areas in which the health enterprises have procedures that conform to national quality requirements, but where it is still unclear whether they are observed in practice. Areas for improvement relate to routines describing areas of responsibility, availability of personnel resources and staff training.

Background: Symphysis-fundus measurement is used in pregnancy care to detect poor fetal growth. Symphysis-fundus measurement curves (percentile curves) and prediction of fetuses with a birth weight below the10th percentile have been published previously. The percentile curves show the distribution of symphysis-fundus measurements in the reference population and are recommended as the national standard. This article discusses the predictive value of this method for identification of neonates who are small for gestational age (SGA)., Material and Method: This is a population-based registry study of pregnant women who gave birth at Sahlgrenska University Hospital in Gothenburg in the period 2005 – 2010. Diagnostic accuracy was analysed using ROC curves and presented with the area under the curve (AUC) from gestational week 24 to 42. Sensitivity, specificity, and positive and negative predictive value were calculated., Results: A total of 42 018 pregnant women carrying a single fetus were included. The AUC values showed that a symphysis-fundus measurement late in pregnancy was a stronger predictor for determining fetuses that are small for gestational age than a measurement early in pregnancy. The AUC value increased from 0.61 in week 24 to 0.74 in week 40. With a threshold value at the 10th percentile, symphysis-fundus measurement has a total sensitivity of 47 % and a specificity of 79 %. A positive total test was defined as at least one measurement below the 10th percentile curve in the course of the pregnancy., Interpretation: Symphysis-fundus measurement may be important for the identification of high-risk pregnancies, but should preferably be used in conjunction with other clinical variables.
