x75 Beams manufactured by JINDAL are represented by Web Height, Flange Width & Section Similarly, birthweight varied significantly between countries, even after adjustment for differences in the length of pregnancy. As seen from Table 17, it is as if rigorous selection and exclusions have limited effect, and other uncontrolled factors are responsible for the variation between studies and countries. Institute of Developmental Sciences, University of Southampton, Southampton, United Kingdom, Affiliations Although widely adopted, the applicability of these child growth standards has been questioned on the grounds of lack of fit to some populations [15,16], especially for the head circumference standards [17]. The anteroposterior diameter was measured from the spine to the anterior abdominal wall, and the transverse diameter at a right angle to the anteroposterior diameter. Birthweight was assessed at delivery, and neonatal morphometry carried out within 24 h according to the protocol [20]. While overall median BMI was 23.1 kg/m2, the median by country ranged from 21.6 kg/m2 in Thailand to 25.9 kg/m2 in Egypt. Using country as a covariate in a quantile regression model, including interaction terms with gestational age, showed significance at the 5% level for all percentiles 5th, 10th, 25th, 50th, 75th, 90th, and 95th (S2 and S3 Tables).

All women other than those withdrawing consent were included in the growth curve analyses if they contributed ultrasound information, with the number in this analysis being 1,362. https://doi.org/10.1371/journal.pmed.1002220.t001. Choose the required beam span in the left column. Graphs of the 10th, 50th, and 90th percentiles for the ultrasound measure AC in millimeters for the ten participating countries. Interestingly, there was a significant difference in the growth of EFW between countries that was not explained by maternal factors (Fig 3; S2 Table). In 2006, WHO published the multicenter WHO Child Growth Standards [12] using a prescriptive concept that assumes that, under optimal socioeconomic and nutritional conditions, all children follow one growth standard, regardless of ethnic background. We thank José de Souza Ramos for his contributions to the programming of descriptive tables and creation of analysis files. Channels. Lay the tape along the outer curve of the beam so that the top edge of the tape coincides with top edge of the beam on both sides of the point to This variation due to country was adjusted for maternal characteristics (mother’s age, parity, height, and weight, or with BMI substituting the latter two) and sex of the fetus. The median of the three measurements of each parameter was used in the analyses. Country variation in the other ultrasound parameters for the 10th, 50th, and 90th percentiles is presented in S2–S6 Figs. In addition to globally experienced maternal complications such as preeclampsia, pregnancy-induced hypertension, gestational diabetes, and anemia, 42 had identified malaria. The measurement was obtained from an image with the midline echo as close as possible to the horizontal plane, 90 degrees to the ultrasound beam. Median maternal height ranged from 155 cm (India) to 169 cm (Germany), and weight from 54 kg (Thailand) to 66 kg (Germany). Yes Data Availability: Data are available upon request from Ms. Catherine Hamill (hamillc@who.int). Department of Obstetrics and Gynecology, School of Medical Sciences, University of Campinas, Campinas, Brazil, Affiliation Figs 4 and 5 show the variation of country-specific percentiles compared with the corresponding overall percentiles of the study and provide an opportunity to assess the magnitude and clinical relevance of the observed variation. There were also significant differences in growth of EFW between countries. ASTM A6. Height of the mother was measured in the standing position using a stadiometer and recorded to the nearest millimeter. Weight wearing light clothing was measured using a beam balance with nondetachable weights and recorded to the nearest 0.1 kg. A meeting of experts convened by WHO in 2002 reviewed current knowledge on birthweight as a health outcome and identified a need for research to develop fetal growth charts for international use [11]. et al. The asymmetry and kurtosis of the fitted distributions may thus assume any form dictated by the data, even changing with gestational age. Thirty-one women had a miscarriage, and three fetuses had intrauterine death. The choice of participating centers was based on their proficient use of ultrasound by experienced sonographers. We are not sure of the nature of the small negative asymmetry in early pregnancy, but speculate that regulatory functions, such as the process of maternal constraint of fetal growth, change through gestation, i.e., fetuses in the higher percentiles may be exposed to greater influences, which vary with maternal characteristics. Yes The median birthweight was 3,300 g (IQR 2,980–3,615). Importantly, more than 60% of such deaths are associated with low birthweight due to intrauterine growth restriction or preterm birth or both [4,5]. Fetuses diagnosed with any anomaly were managed according to local clinical guidelines. Example: A 14'-0" span beam carries 15'-0" simple span joists on each side. The study was, however, restricted to four self-reported ethnic groups of Asian, Hispanic, black, and white women in the US. https://doi.org/10.1371/journal.pmed.1002220.g002, https://doi.org/10.1371/journal.pmed.1002220.t014, https://doi.org/10.1371/journal.pmed.1002220.t015. All pregnant women in the study were asked for a 24-h dietary recall at entry into the study (and at 28 and 36 wk of gestation) [22]. Variation in fetal growth within and between populations should therefore not be ignored. Even influences on fetal growth classically thought to be primarily genetic, such as maternal and paternal height, are complicated by environmental factors. 4. A further refinement would be to introduce conditioning terms when using repeated ultrasound measurements for monitoring growth [46,47], i.e., narrowing the expected reference interval for an assessment by conditioning it using a previous measurement. Recently, a large multicenter study, the Fetal Growth Longitudinal Study of the Intergrowth-21st Project [18], applied the same concept and approach to fetal growth. Is the Subject Area "Charts" applicable to this article? Yes Full models fitted a polynomial on gestational age for each country by including interaction terms between gestational age polynomial and country. Measurements and 2-D/3-D images corresponding to fetal biometry had special processing. No, PLOS is a nonprofit 501(c)(3) corporation, #C2354500, based in San Francisco, California, US, https://doi.org/10.1371/journal.pmed.1002220, https://doi.org/10.1371/journal.pmed.1003526, https://doi.org/10.1371/journal.pmed.1002284, http://www.who.int/gho/child_health/mortality/neonatal/en/. The following measurement techniques were used. Measure Weight Infancy and Early Childhood •• Weigh younger infants nude or in a clean diaper on a calibrated beam or electronic scale. (2021) Country differences in EFW percentiles and overall EFW percentiles are presented in S4 Table. The study confirmed the biologically interesting facts that fetal sex and maternal height, weight, parity, and age significantly influence fetal growth [31,36,37]. Databases for Academic Institutions. The superimposed dead load (SDL) is 1.15 kip/ft with other given quantities below. The Bowley coefficient of asymmetry [29], based on differences of semi-quartile ranges relative to the quartile range, was −0.016 for gestational age 15 wk and +0.111 for 40 wk. Service de Gynecologie Obstetrique, Hôpital Antoine-Béclère, AP-HP, Université Paris Sud, Clamart, France, Affiliation The type of load in question will also determine how much weight a 2x6 can hold on edge. Gestational age was included in the model with polynomial terms (linear, quadratic, and cubic). ˜æ–0:tvþƒp!®Ñ÷PeWVôg³5ɵßw/­-šl)गwY1¥7YÑ-êlùÞϪÚÍÒª=‘§‡5aaœ^•×E¡,‘,œÆ²`HuçfõmGÊ6›. During pregnancy, repeated ultrasound measurements were used to establish international fetal growth charts for head and abdominal circumference, length of the thigh bone, and fetal weight, estimated using a combination of the three measurements. Interestingly, the 10th percentile for the Intergrowth-21st Project results seems to fall below that of the WHO study, even though the Intergrowth-21st Project study was carried out according to a strictly “prescriptive” concept to establish so-called optimal fetal growth (low-risk pregnancies with no environmental and nutritional constraints, and excluding all conditions during pregnancy and childbirth that may be associated with effects on fetal growth).

Congo, Denmark, Germany, and Norway and highest in Egypt and India. AC, There was asymmetric distribution of growth of EFW: a slightly wider distribution among the lower percentiles during early weeks shifted to a notably expanded distribution of the higher percentiles in late pregnancy. The distribution of EFW starts with a slight asymmetry to the left (i.e., lower percentiles) in early pregnancy and ends with a very noticeable right asymmetry (i.e., higher percentiles) in later pregnancy. https://doi.org/10.1371/journal.pmed.1002220.g005. When adjusted for gestational age at birth, the differences were still significant for all the percentiles (p = 0.0018 for the 5th percentile and p < 0.001 for the 10th, 25th, 50th, 75th, 90th, and 95th percentiles). The median pregnancy duration was 39 wk (IQR 38–40) although there were significant differences between countries, the largest difference being 12 d (95% CI 8–16). These plots are intended to enable the reader to derive the magnitude of difference in grams for any size and country and percentile. The clinical relevance of the differences between the country quantiles and the global quantiles can be assessed in quantile–quantile plots (Fig 4). We believe that the present WHO fetal growth charts can be used internationally, particularly where no local data exist. … 52-AC-CLAMP Channel x 12’ (accepts Light I-Beam) Aluminum Association I-Beam 6” Pulley Ear Bracket x 12’ 25-61-599 6005 for 6 x 4 I-Beams for Boat Lifts 8” Pulley Ear Bracket x 12’ 25-61-600 6005 for 8 x 5 I-Beams forLifts Country variation gives Wald chi-square = 36 (9 df); sex of the fetus, 29 (1 df); mother’s height, 26 (1 df); and mother’s age, 22 (1 df), while the Wald chi-square value for weight is negligible. The woman was eligible for the study provided that gestational age by crown–rump length confirmed LMP-based age within 7 d. The LMP-based age was used for the analyses. Citation: Kiserud T, Piaggio G, Carroli G, Widmer M, Carvalho J, Neerup Jensen L, et al. = density of a material (unit weight) = summation symbol The cross section shape and how it resists bending and twisting is important to understanding beam and column behavior. A total of 1,439 women were enrolled between October 2009 and September 2014, with data collection being completed with the last childbirth in April 2015. For e.g. … The pregnancy conditions (e.g., complications) that the study population experienced are those common to low-risk pregnancies around the world. Department of Obstetrics and Gynecology, Faculty of Medicine, Assiut University, Assiut, Egypt, Affiliation Global mortality for infants under age 5 y halved from 90 to 43 deaths per 1,000 live births between 1990 and 2015. Another recently published multinational study by the Intergrowth-21st Project presented biometric growth but not EFW data [18]. Although the present study was not designed to investigate ethnic differences, a limited record of participants’ ethnicity showed a distribution largely according to country (Table 2). This shape is very efficient for carrying loads of weight without bending. Carvalho J, Carroli G, There were differences in birthweight between countries, e.g., India had significantly smaller neonates than the other countries, even after adjusting for gestational age. Neonatal mortality in the first 28 d declined (by 47%) from 5.0 to 2.6 million deaths annually over this period. Starting with a higher distribution towards the lower percentiles, EFW shifts to an expanded distribution among the higher percentiles and ends with a noticeable asymmetry near term. Medical Statistics Department, London School of Hygiene &Tropical Medicine, London, United Kingdom, Democratic Republic of the Congo; EFW, The WHO study had a similar recruitment but retained in the analysis pregnancies with maternal, fetal, and neonatal clinical conditions, based on the principle that reference intervals should reflect as closely as possible the population to which they will be applied. https://doi.org/10.1371/journal.pmed.1002220.s002. Most of an I-beam’s cross sectional area is located away from the neutral axis of the beam, resulting in a high moment of inertia, or “I Carroli G, Further details are available elsewhere [20]. A strength of the new growth charts provided by the study (Tables 6–15) is that they are based on multinational data, i.e., ten countries, and therefore are more likely to be applicable internationally than previously published reference intervals for EFW based on single countries. Gestational age was confirmed by measuring the crown–rump length between gestational week 8 + 0 d and 12 + 6 d based on LMP and recorded as the average of three measurements.
