Zinc, antioxidant enzymes in preeclampsia, and association with newborn outcome.

BACKGROUND: The etiology of preeclampsia (PE) may be associated with the increased of production of reactive species and decreased antioxidant activity of enzymes. Inadequate intake of Zn can affect gestational health due to its biological functions, such as its role in the antioxidant defense system. The study aimed to assess the nutritional status of Zn and antioxidant enzymes in postpartum women and its correlation with neonatal outcomes. METHODS: A cross-sectional analytical study was carried out at a referral gynecology and obstetrics hospital. A total of 119 women (PE = 58, HP = 61) participated in the study. A quantitative food-frequency questionnaire was used to assess food consumption and further analyze the dietary Zn levels. Zinc levels in plasma and erythrocytes samples were analyzed by flame atomic absorption spectrometry, catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) levels were determined by UV-Vis spectrophotometry. RESULTS: Plasma and dietary intake Zn results were considered adequate and without statistical difference between groups. SOD levels were significantly higher in the HP group (p = 0.011), and CAT levels were higher in the PE group (p = 0.050). There was a positive correlation between SOD activity in women with PE and the weight of their newborns (r = 0.336, p=0.021). CONCLUSION: The results showed adequate Zn levels (consumption and serum levels) in the groups studied, although with a reduction of plasma Zn in the PE group compared to the PH group. Zinc in plasma fractions and erythrocytes are important markers for oxidative stress, in particular, plasma Zn seems to be related to the rapid response to preeclampsia. The activity of antioxidant enzymes was elevated in the groups studied. Better SOD activity improves birth weight in children of pregnant women with preeclampsia.

Introduction: Ultrasonographic assessment of fetal weight allows assessment of fetal growth and well-being and can estimate birth weight, a determining factor for vital prognosis. Objectives: Determine the ultrasound margin of error of the estimated fetal weight (EFP) in relation to the birth weight of neonates at the Maternity Hospital of the Hospital de Clínicas between the years 2020 and 2022. Materials and Methods: An observational, descriptive and cross-sectional study was carried out on women who had their birth in the aforementioned place and period and who had an obstetric growth ultrasound performed less than 7 days after birth. The error of the EPF was calculated using the formula: (Birth Weight - Estimated Fetal Weight) / Birth Weight) x 100. The error of the estimated fetal weight was contrasted with the body mass index, diabetes and hypertensive state of pregnancy, using Student's t and with gestational age and maternal age using the Pearson index taking statistically significant values ​​less than 0.05. Results: 258 patients were included. The ultrasound margin of error of the EPF was 8.3% SD ± 7. A p value was obtained for BMI of 0.228, diabetes p 0.915, hypertensive states p 0.967, days in which the ultrasound was performed p 0.5 and age gestational p 0.001. Conclusions: The ultrasound margin of error of the EPF is below the international parameters. Statistically significant associations were found with gestational age, but not with the other variables.

Morphometric Evaluation of Human Placental and Umbilical Cord for Neonatal Indices: A Cross-Sectional Study.

BACKGROUND: In India, there is only limited data on studies related to umbilical cord and placental indices in newborn infants. The present study was undertaken to evaluate the morphometric analysis of placental and umbilical cord indices and their association with length, weight, and head size in newborns. MATERIALS AND METHODS: This was a longitudinal cross-sectional study conducted on placentas and fetal measures from 245 women who gave birth during the study period. The placental variables, umbilical cord indices, and neonatal indices were measured. The association between the parameters was done using Pearson's correlation, and p<0.05 was considered statistically significant.  Results: The placental weight (p=0.01) and placental volume (p=0.01) showed a significant positive correlation with newborn weight. The mean placental diameter was 16.32 ± 1.54 cm, and there was no significant correlation between placental diameter and infant weight (p=0.232), length (p=0.658), or head circumference (0.842). In addition, there was a significant association between placental diameter, placental volume (p=0.000), and placental weight (p=0.000). There was a significant positive correlation (p<0.05) between ponderable index and birth weight, length, and head circumference. CONCLUSION: Placental weight and newborn weight were significantly associated in this study. The length of the umbilical cord was found to be related to placental weight. So, placental measurements are reliable indicators for the assessment of fetal wellbeing.

Controversies and Conundrums in Newborn Feeding.

Breastfeeding is the biologic norm for newborn feeding, and exclusive breastfeeding for the first 6 months of life is universally endorsed by leading global and national organizations. Despite these recommendations, many people do not meet their breastfeeding goals and controversies surrounding breastfeeding problems exist. Medical issues can present challenges for the clinician and parents to successfully meet desired feeding outcomes. There are studies evaluating these common controversies and medical conundrums, and clinicians should provide evidence-based recommendations when counseling families about newborn feeding.

Placental weight and its relationship with the birth weight of term infants and body mass index of the mothers.

OBJECTIVE: Placental pathology is a well-known cause of perinatal and neonatal mortality and morbidity, and may correlate with placental growth, which can be assessed indirectly by anthropometric placental measurements. The aim of this cross-sectional study was to investigate mean placental weight and its relationship with birthweight and maternal body mass index (BMI). METHODS: Fresh (not formalin fixed) consecutively delivered placentae of term newborns (37-42 weeks), collected between February 2022 and August 2022, and the mothers and newborns, were included. Mean placental weight, birthweight and maternal BMI were calculated. Pearson's correlation coefficient, linear regression, and one-way analysis of variance were used to analyse continuous and categorical data. RESULTS: Out of 390 samples, 211 placentae (with 211 newborns and mothers) were included in this study after exclusion criteria were applied. Mean placental weight was 494.45 ± 110.39 g, and mean term birth weight/placental weight ratio was 6.21 ± 1.21 (range, 3.35-11.62 g). Placental weight was positively correlated with birthweight and maternal BMI, but not with newborn sex. Linear regression effect estimation of placental weight on birthweight revealed a medium correlation (R2 = 0.212; formula, 1.4553 × X + 2246.7, where X is placental weight [g]). CONCLUSION: Placental weight was revealed to positively correlate with birthweight and maternal BMI.

Placental levels of essential and non-essential trace element in relation to neonatal weight in Northwestern Spain: application of generalized additive models.

Adequate gestational progression depends to a great extent on placental development, which can modify maternal and neonatal outcomes. Any environmental toxicant, including metals, with the capacity to affect the placenta can alter the development of the pregnancy and its outcome. The objective of this study was to correlate the placenta levels of 14 essential and non-essential elements with neonatal weight. We examined relationships between placental concentrations of arsenic, cadmium, cobalt, copper, mercury, lithium, manganese, molybdenum, nickel, lead, rubidium, selenium, strontium, and zinc from 79 low obstetric risk pregnant women in Ourense (Northwestern Spain, 42°20'12.1″N 7°51.844'O) with neonatal weight. We tested associations between placental metal concentrations and neonatal weight by conducting multivariable linear regressions using generalized linear models (GLM) and generalized additive models (GAM). While placental Co (p = 0.03) and Sr (p = 0.048) concentrations were associated with higher neonatal weight, concentrations of Li (p = 0.027), Mo (p = 0.049), and Se (p = 0.02) in the placenta were associated with lower newborn weight. Our findings suggest that the concentration of some metals in the placenta may affect fetal growth.

Abnormal Maternal Body Mass Index and Customized Fetal Weight Charts: Improving the Identification of Small for Gestational Age Fetuses and Newborns.

BACKGROUND: Obesity and thinness are serious diseases, but cases with abnormal maternal weight have not been excluded from the calculations in the construction of customized fetal growth curves (CCs). METHOD: To determine if the new CCs, built excluding mothers with an abnormal weight, are better than standard CCs at identifying SGA. A total of 16,122 neonates were identified as SGA, LGA, or AGA, using the two models. Logistic regression and analysis of covariance were used to calculate the OR and CI for adverse outcomes by group. Gestational age was considered as a covariable. RESULTS: The SGA rates by the new CCs and by the standard CCs were 11.8% and 9.7%, respectively. The SGA rate only by the new CCs was 18% and the SGA rate only by the standard CCs was 0.01%. Compared to AGA by both models, SGA by the new CCs had increased rates of cesarean section, (OR 1.53 (95% CI 1.19, 1.96)), prematurity (OR 2.84 (95% CI 2.09, 3.85)), NICU admission (OR 5.41 (95% CI 3.47, 8.43), and adverse outcomes (OR 1.76 (95% CI 1.06, 2.60). The strength of these associations decreased with gestational age. CONCLUSION: The use of the new CCs allowed for a more accurate identification of SGA at risk of adverse perinatal outcomes as compared to the standard CCs.

The effect of Pimpinella Anisum herbal tea on human milk volume and weight gain in the preterm infant: a randomized controlled clinical trial.

BACKGROUND AND AIMS: Human milk supports pre-term infants to thrive. Yet human milk production can be inhibited when infants are born prematurely. Pimpinella Anisum has been evidenced to increase milk production and infant weight gain in previous animal studies. The present study aimed to determine the effect of Pimpinella Anisum herbal tea on human milk volume and preterm infant weight in human populations for the first time. METHODS: Human milk supports pre-term infants to thrive. Yet human milk production can be inhibited when infants are born prematurely. Pimpinella Anisum has been evidenced to increase milk production and infant weight gain in previous animal studies. The present study aimed to determine the effect of Pimpinella Anisum herbal tea on human milk volume and preterm infant weight in human populations for the first time. RESULTS: There was a statistically significant difference in terms of milk volume in the first, third, fourth, fifth, sixth and seventh days between the three groups of intervention, placebo, and control (p < 0.05). On the first day, the mean volume of pumped milk in the intervention group was significantly higher than the control group (p = 0.008). On the second day, there was no statistically significant difference between groups. On the third, fourth, fifth, sixth and seventh days, the mean volume of pumped milk in the intervention group was significantly higher than the placebo and control groups (p < 0.05). There was no statistically significant difference in terms of preterm infant weight on days 0, 3 and 7 between the three groups. CONCLUSION: The use of Pimpinella Anisum or 'Anise' tea can increase the volume of human milk and since no specific side effects have been reported in its use, it may be incorporated easily, cheaply, and effectively in practice where appropriate to the benefit of preterm infant nutrition worldwide.

Newborn Weight Loss as a Predictor of Persistence of Exclusive Breastfeeding up to 6 Months.

Objectives: To investigate the association between neonatal weight loss and persistence of exclusive breastfeeding up to 6 months. Study Design: An observational cohort study in the setting of a Baby Friendly Hospital, enrolling 1,260 healthy term dyads. Neonatal percentage of weight loss was collected between 48 and 72 h from birth. Using a questionnaire, all mothers were asked on the phone what the infant's mode of feeding at 10 days, 42 days and 6 months (≥183 days) from birth were. The persistence of exclusive breastfeeding up to 6 months and the occurrence of each event that led to the interruption of exclusive breastfeeding were verified through a logistic analysis that included 40 confounders. Results: Infants with a weight loss ≥7% were exclusively breastfed at 6 months in a significantly lower percentage of cases than infants with a weight loss <7% (95% CI 0.563 to 0.734, p < 0.001). Weight loss ≥7% significantly increases the occurrence of either sporadic integration with formula milk (95% CI 0.589 to 0.836, p < 0.001), complementary feeding (95% CI 0.460 to 0.713, p < 0.001), exclusive formula feeding (95% CI 0.587 to 0.967, p < 0.001) or weaning (95% CI 0.692 to 0.912, p = 0.02) through the first 6 months of life. Conclusions: With the limitations of a single-center study, a weight loss ≥7% in the first 72 h after birth appears to be a predictor of an early interruption of exclusive breastfeeding before the recommended 6 months in healthy term exclusively breastfed newborns.

Does predelivery body mass index really matter in pregnancy?

OBJECTIVES: The aim of the study was to compare the perinatal outcome between the normal weight, overweight and obese pregnant women who delivered in the third-level center of reference. Moreover, the objective was to analyze the usefulness of predelivery body mass index (BMI) in prediction of preterm delivery, prolonged second stage of labor, instrumental vaginal delivery, cesarean section, fetal macrosomia, dystocia and newborn acidosis. MATERIAL AND METHODS: The retrospective study included 2104 patients, divided into three groups, with BMI between 18.5 and 24.9; 25.0 and 29.9; higher than or equal 30.0 kg/m2, respectively. The data were assessed from the medical history. RESULTS: The predelivery obesity increases the risk of cesarean section (aOR 1.63), macrosomia (aOR 8.89) and dystocia (aOR 3.40) in comparison to normal weight women. Moreover, the obese females had three times greater risk of having a macrosomic child (aOR 3.57) and 1.5 times greater risk of cesarean section (aOR 1.52) than overweight group. The role of predelivery BMI in the prediction of cesarean delivery (AUC 0.550; sensitivity 0.39; specificity 0.71, p < 0.001, cut-off value 28.7 kg/m2), macrosomia (AUC 0.714; sensitivity 0.66; specificity 0.70; p < 0.001, cut-off value 29.0 kg/m2) and dystocia (AUC 0.658; sensitivity 0.77; specificity 0.53, p < 0.001, cut-off value 27.0 kg/m2) was significant. CONCLUSIONS: The predelivery obesity increases the risk of cesarean section, macrosomia and shoulder dystocia and is a useful parameter in the prediction of perinatal outcomes. The establishing cut-off value for predelivery BMI was the lowest in prediction of shoulder dystocia.

Can recurrent cesarean section due to arrest of descent be predicted by newborn weight difference?

OBJECTIVE: To evaluate if newborn weight difference is associated with the mode of delivery in women with a previous cesarean section due to arrest of descent. STUDY DESIGN: This retrospective cohort analysis included all women admitted to the delivery room of Carmel Medical Center with a singleton fetus at vertex presentation and a prior cesarean section for arrest of descent. A comparison was made between women who had a subsequent successful vaginal birth after cesarean delivery vs. a repeat cesarean section for arrest of descent. The primary outcome was newborn weight difference between the previous cesarean section and the present delivery. Secondary outcomes were gestational age, gravidity, age, induction of labor, previous vaginal birth and epidural analgesia. RESULTS: Of 179 women with a prior cesarean section due to arrest of descent, 55 women (30.7 %) underwent an elective repeat cesarean section. Of the remaining 124 women, 95 women (76.6 %) achieved a vaginal delivery. Out of the 29 cases who underwent a repeat cesarean section, 18 women had a cesarean section for arrest of descent. Women who achieved vaginal delivery were more likely to be with higher gravidity, a previous vaginal delivery and a lower rate of epidural anesthesia. Following multivariate logistic regression, the women who required a cesarean section due to arrest of descent, had significantly higher birth weight in the current than in the previous pregnancy, compared to women achieving vaginal delivery (Odds Ratio 4.7, CI 95 % 1.4-15.7, P = 0.012). CONCLUSION: Current birth weight higher than the previous newborn weight in a cesarean section for arrest of descent is associated with lower likelihood of successful vaginal birth after cesarean delivery and therefore should be taken in consideration during fetal weight estimation and the decision on the mode of delivery. This issue should be explored in future prospective large-cohort studies.

Transperineal Ultrasound Assessment of a Cystocele's Impact on the Bladder Neck Mobility in Women with Stress Urinary Incontinence.

Background and objectives: As pelvic floor disorders are often difficult to assess thoroughly based on clinical examination alone, the use of imaging as a complementary technique is helpful. This study's aim was to investigate by transperineal ultrasound (US) if there was any significant difference in the mobility of the bladder neck in women with stress urinary incontinence (SUI) without a cystocele and in those with SUI and an associated cystocele. The study also investigated whether the number of vaginal births and/or the heaviest newborn's birth weight was correlated with the bladder neck mobility. Materials and Methods: A total of 71 women suffering from SUI were included in the study and divided into two groups based on the presence of a cystocele. Their bladder neck mobility was evaluated by transperineal US, calculating the distance from the inferior margin of the symphysis pubis to the bladder neck (SPBN), and the dorsocaudal linear movement (DLM), term used to illustrate the displacement of the bladder neck by subtracting rest and Valsalva values. GraphPad Prism 8 was used for statistical analysis. Results: Within both study groups, the SPBN values were significantly higher and the DLM values were significantly lower at rest as compared to Valsalva maneuver (p < 0.05). No significant difference between the groups regarding SPBN and DLM values at rest, Valsalva, or subtraction was demonstrated. A significant positive correlation was found between the bladder neck mobility and the heaviest newborn's birth weight, regardless of the presence of a cystocele (p = 0.042). Conclusions: The presence of a cystocele had no significant impact on the bladder neck mobility measurements in patients with SUI. The heaviest newborn's birth weight positively correlated with bladder neck hypermobility, as quantified by SPBN.

The relationship between maternal weight gain in pregnancy and newborn weight.

AIM: This study investigated the impacts of different pre-pregnancy body mass indexes and gestational weight gain on the risk of delivering a high birth weight infant in China. METHODS: A retrospective cohort study was conducted from 2013 to 2014 in the Maternal and Child Health Care Hospital of Jinan City, Shandong Province and 2415 women who had a singleton birth were included in the study. A logistic regression model and restricted cubic spline regression were used to analyse the association. FINDINGS: The risk of delivering a high birth weight infant increases when the mother's pre-pregnancy body mass index exceeds 24kg/m2. Compared with women whose pre-pregnancy body mass index was 21kg/m2, the adjusted risk of delivering a high birth weight infant doubled when the mother's pre-pregnancy body mass index was 29kg/m2, and nearly tripled when the mother's pre-pregnancy body mass index was 31kg/m2. Compared with women who had a gestational weight gain of 12.0kg, women having a gestational weight gain of 20.0kg, 22.0kg, and 26.0kg had a 1.7-, 2.2-, and 3.5-fold increased risk of delivering a high birth weight infant. When the mother experiences a gestational weight gain greater than 27kg, the risk of delivering a high birth weight infant is at least 4-fold greater than that for a mother who has a gestational weight gain of 12.0kg. CONCLUSIONS: Proposed strategies to raise public awareness of the risks to infants posed by high maternal pre-pregnancy body mass index and gestational weight gain are required. All clinical recommendations and measures are for all pregnant women, not just overweight and obese pregnant women.

Newborn weight change and childhood cardio-metabolic traits - a prospective cohort study.

BACKGROUND: Newborn weight change (NWC) in the first 4 days represents short-term adaptations to external environment. It may be a key developmental period for future cardio-metabolic health, but this has not been explored. We aimed to determine the associations of NWC with childhood cardio-metabolic traits. METHODS: As part of Generation XXI birth cohort, children were recruited in 2005/2006 at all public units providing obstetrical and neonatal care in Porto. Birthweight was abstracted from clinical records and postnatal anthropometry was obtained by trained examiners during hospital stay. NWC was calculated as ((minimum weight - birthweight)/birthweight) × 100. At age 4 and 7, children were measured and had a fasting blood sample collected. Fasting glucose, LDL-cholesterol, triglycerides, waist circumference, systolic and diastolic blood pressure were evaluated. This study included 312 children with detailed information on growth in very early life and subsequent cardio-metabolic measures. Path analysis was used to compute adjusted regression coefficients and 95% confidence intervals. RESULTS: NWC was not associated with any cardio-metabolic traits at ages 4 or 7. Strong associations were observed between each cardio-metabolic trait at 4 with the same trait at 7 years. The strongest associations were found for waist circumference [0.725 (0.657; 0.793)] and LDL-cholesterol [0.655 (0.575; 0.735)]. CONCLUSIONS: No evidence that NWC is related to childhood cardio-metabolic traits was found, suggesting that NWC should be faced in clinical practice as a short-term phenomenon, with no medium/long term consequences, at least in cardio-metabolic health. Our results show strong tracking correlations in cardio-metabolic traits during childhood.

[Relationships between umbilical vein and mother iron status].

INTRODUCTION: Iron is an essential micronutrient in the growing fetus. OBJECTIVE: The purpose of this study is to find the possible correlations that may exist between maternal and fetal iron status and newborn weight. MATERIAL AND METHODS: The study included 97 mothers scheduled to give birth by elective caesarean section in the central maternity of Tébessa (east of Algeria) between January and August 2014. The blood collection was sampled from the antecubital vein of the mother and the umbilical vein. The mean concentrations of parameters in maternal and fetal sides, respectively, were 10.64 ± 1.37 g/dl and 14.83 ± 1.79 g/dl for hemoglobin, 51.57 ± 20.82 µg/dl and 112.47 ± 32.34 µg/dl for serum iron, and 12.37 ± 9.58 ng/ml and 109.64 ± 58.76 ng/ml for serum ferritin. Except for ferritin, other fetal parameters were correlated with those of mothers. Birth weight was only significantly correlated with maternal hemoglobin (r = 0.22, p = 0.02) and hematocrit (r = 0.2, p = 0.004). CONCLUSION: The fetal-maternal exchanges of iron were highlighted and iron status of the newborn was linked to that of the mother. The low maternal hemoglobin was associated with low newborn weight.

Impact of maternal respiratory infections on low birth weight - a community based longitudinal study in an urban setting in Pakistan.

BACKGROUND: The health of mothers and their newborns is intricately related. The weight of the infant at birth is a powerful predictor of infant growth and survival, and is considered to be partly dependent on maternal health and nutrition during pregnancy. We conducted a longitudinal study in an urban community within Karachi to determine maternal predictors of newborn birth weight. METHODS: Four hundred pregnant women were enrolled in the study during the period 2011-2013. Data related to symptoms of acute respiratory illness (fever, cough, difficulty breathing, runny nose, sore throat, headache, chills, and myalgia/lethargy) in the pregnant women were collected weekly until delivery. Birth weight of the newborn was recorded within 14 days of delivery and the weight of <2.5 kg was classified as low birth weight (LBW). RESULTS: A total of 9,853 symptom episodes were recorded of fever, cough, difficulty breathing, runny nose, sore throat, headache, chills, myalgias/lethargy in the enrolled pregnant women during the study. Out of 243 pregnant women whose newborns were weighed within 14 days of birth, LBW proportion was 21% (n = 53). On multivariate analysis, independent significant risk factors noted for delivering LBW babies were early pregnancy weight of < 57.5 kg [odds ratio adjusted (ORadj) = 5.1, 95% CI: (1.3, 19.9)] and gestational age [ORadj = 0.3, 95% CI (0.2, 0.7) for every one week increase in gestational age]. Among mothers with high socioeconomic status (SES), every 50-unit increase in the number of episodes of respiratory illness/100 weeks of pregnancy had a trend of association with an increased risk of delivering LBW infants [ORadj = 1.7, 95% CI: (1.0, 3.1)]. However, among mothers belonging to low SES, there was no association of the number of episodes of maternal respiratory illness during pregnancy with infants having LBW [ORadj = 0.9, 95% CI: (0.5, 3.5)]. CONCLUSIONS: While overall respiratory illnesses during pregnancy did not impact newborn weight in our study, we found this trend in the sub-group of mothers belonging to the higher SES. Whether this is because in mothers belonging to lower SES, the effects of respiratory illnesses were overshadowed by other risk factors associated with poverty need to be further studied.

Weight following birth and childhood dietary intake: A prospective cohort study.

OBJECTIVES: Unhealthy childhood dietary habits track through life and are independent and modifiable risk factors for disease. Therefore, it is essential to understand the factors involved. We aimed to evaluate the associations of birthweight (BW) and newborn weight change (NWC) during the first 96 h of life and childhood longitudinal weight trajectories with dietary intake at age 4. METHODS: As part of the Generation XXI birth cohort (G21), children were recruited in 2005 and 2006 at all public units providing obstetrical and neonatal care in Porto, Portugal. Information was collected by face-to-face interview and abstracted from clinical records. At age 4, weight measurements recorded from birth to current age were abstracted and weight trajectories estimated. Food frequency questionnaires were applied, and three dietary patterns (DPs) were identified: "Energy-dense food (EDF)+Dairy," "Lower in Healthy Food," and "Healthier." Logistic regression models were used to compute the odds ratio (OR) and 95% confidence intervals (CIs) (OR [95% CI]) in a sample of 775 children. RESULTS: Children with higher BW were less frequently in the "EDF+Dairy" DP (0.94 [0.89-0.98] per 100 g increase in BW). Children with higher NWC had lower odds of eating fruit ≥3/d (0.93 [0.87-0.99] per 1% increase in NWC). Children with higher weight during childhood had higher odds of belonging to the "EDF+Dairy" DP (1.90 [1.04-3.47]) and lower odds of eating vegetable soup ≥2/d (0.56 [0.34-0.91]). Children showing catch-up grow in the first year of life had higher odds of eating dairy products ≥3/d (3.76 [1.31-10.80]). CONCLUSIONS: The way that children grow during childhood played a major role on dietary intake at age 4.

Systematic review of the methodological quality of studies designed to create neonatal anthropometric charts.

UNLABELLED: Babies all over the world are assessed at birth using neonatal anthropometric charts as a matter of clinical routine. This systematic review evaluated the methodological quality of studies designed to create neonatal anthropometric charts and to highlight features in the charts that could affect clinical decision-making and comparisons between populations. The variety and quality of available charts could affect how newborns at risk are identified, together with the indications for treatment, especially nutritional interventions. CONCLUSION: The studies that generated the charts currently recommended for clinical use have major methodological limitations and international and regional comparisons are very difficult.
