    Previous studies suggest that Ramadan exposure during pregnancy might affect the health of women and their babies, particularly through the effect of fasting. This study aimed to evaluate the association between Ramadan exposure and fasting during pregnancy on the birth weight of newborns. This study concerned 1351 pregnant women from a prospective cohort in Jakarta, Indonesia. Ramadan exposure was based on the actual overlap between Ramadan and pregnancy. Women's fasting behaviour was recorded among 139 women who came for antenatal care between 10 July 2013 and 7 August 2013, and those who had fasted for at least 1 d ( n 110) were classified as exposed to Ramadan fasting. Furthermore, a 24 h dietary recall was performed and repeated 1 month later. Birth weight of newborns who were exposed to Ramadan during pregnancy did not significantly differ from those who were not, both in the total and trimester-specific analysis. Maternal fasting did not seem to affect the birth weight of newborns (-72 (95 % CI -258, 114) g; P = 0·44), although there was a non-significant trend towards lower birth weight with fasting in the second and third trimester. Women who fasted had significantly lower total energy, macronutrient and water intake as compared with women who did not. Women's intake was also lower during Ramadan (regardless of their fasting behaviour) as compared with 1 month later. Lifestyle changes that occur with Ramadan and fasting during pregnancy are associated with lower reported energy intake. We cannot conclude on the effect of fasting on birth weight due to low statistical power.

    Gestational weight gain is an important predictor of the health of the newborn. It is affected by body mass index of the women. This study was conducted to find out gestational weight gain according to Institute of Medicine 2009 recommendation and relationship of newborn birth weight to body mass index and gestational weight gain of the women. It was cross sectional, hospital based study. The women, who attended at term pregnancy for delivery and having recorded first trimester body weight, were included in the study. Their body mass index was calculated and they were stratified into 4 groups according to body mass index. The gestational weight gain was calculated by subtracting first trimester body weight from body weight at the time of admission for delivery. All the women were followed till delivery. The newborn birth weight was taken immediately after delivery. A total of 227 women were enrolled in the study. More than half of the women had normal body mass index. There were 84 (37%) overweight and obese women. Mean gestational weight gain was 10.21 kg, and mean weight of the newborn was 3.05 kg. There were equal number of women who had adequate weight gain and less weight gain according to recommendation. Excess weight gain was seen in 34 (15%) women. Women of higher body mass index and women who had gain more weight during pregnancy had larger newborns. Body mass index and gestational weight gain of the women were important predictors of birth weight of the newborn. There is a positive correlation between gestational weight gain of the women and birth weight of the newborn.

    Full Text Available Birth weight is an early predictor for metabolic diseases and microRNAs (miRNAs are proposed as fetal programming participants. To evaluate the use of dried blood spots (DBS on newborn screening cards (NSC as a source of analyzable miRNAs, we optimized a commercial protocol to recover total miRNA from normal birth weight (NBW, n = 17–20, low birth weight (LBW, n = 17–20 and high birth weight (macrosomia, n = 17–20 newborns and analyzed the relative expression of selected miRNAs by stem-loop RT-qPCR. The possible role of miRNAs on the fetal programming of metabolic diseases was explored by bioinformatic tools. The optimized extraction of RNA resulted in a 1.2-fold enrichment of miRNAs respect to the commercial kit. miR-33b and miR-375 were overexpressed in macrosomia 9.8-fold (p < 0.001 and 1.7-fold, (p < 0.05, respectively and miR-454-3p was overexpressed in both LBW and macrosomia (19.7-fold, p < 0.001 and 10.8-fold, p < 0.001, respectively, as compared to NBW. Potential target genes for these miRNAs are associated to cyclic-guanosine monophosphate (cGMP-dependent protein kinase (PKG, mitogen-activated protein kinase (MAPK, type 2 diabetes, transforming growth factor-β (TGF-βand Forkhead box O protein (FoxO pathways. In summary, we improved a protocol for analyzing miRNAs from NSC and provide the first evidence that birth weight modifies the expression of miRNAs associated to adult metabolic dysfunctions. Our work suggests archived NSC are an invaluable resource in the search for fetal programming biomarkers.

    Full Text Available Abstract Background Low birth weight has been linked to an increased risk to develop obesity, type 2 diabetes, and hypertension in adult life, although the mechanisms underlying the association are not well understood. The objective was to determine whether the metabolomic profile of plasma from umbilical cord differs between low and normal birth weight newborns. Methods Fifty healthy pregnant women and their infants were selected. The eligibility criteria were being born at term and having a normal pregnancy. Pairs were grouped according to their birth weight: low birth weight (LBW, birth weight th percentile, n = 20 and control (control, birth weight between the 75th-90th percentiles, n = 30. Nuclear Magnetic Resonance (NMR was used to generate metabolic fingerprints of umbilical cord plasma samples. Simultaneously, the metabolomic profiles of the mothers were analysed. The resulting data were subjected to chemometric, principal component and partial least squares discriminant analyses. Results Umbilical cord plasma from LBW and control newborns displayed a clearly differentiated metabolic profile. Seven metabolites were identified that discriminate the LBW from the control group. LBW newborns had lower levels of choline, proline, glutamine, alanine and glucose than did the control newborns, while plasma levels of phenylalanine and citrulline were higher in LBW newborns (p Conclusions Low birth weight newborns display a differential metabolomic profile than those of normal birth weight, a finding not present in the mothers. The meaning and the potential utility of the findings as biomarkers of risk need to be addressed in future studies.

    Full Text Available Objective: To compare sub-optimal birth weight (2,500 to 2,999 g term newborns to appropriate for gestational age (birth weight ≥ 3,000 g term newborns, regarding maternal data and newborn morbidity and mortality. Methods: Single term newborns, appropriate for gestational age from a high socioeconomic population (n = 1,242 with birth weight ranging from 2,500 to 2,999 g (Group I were compared to 4,907 newborns with birth weight ≥ than 3,000 g (Group II. Maternal and newborn characteristics were compared between the groups. The Mann-Whitney test, χ2 test and multivariate analysis were used. The significance level adopted was p < 0.05. Rresults: The frequency of sub-optimal birth weight newborns in the population studied was 20.2%. There was a significant association between sub-optimal birth weight and maternal weight before pregnancy and body mass index, maternal weight gain, height, smoking habit and hypertension. Newborns’ 1-minute Apgar score, neonatal hypoglycemia, jaundice, transient tachypnea, congenital pneumonia and hospital stay were significantly different between the groups (p < 0.05. A significant relationship could not be established with the 5-minute Apgar score and pulmonary hypertension in both groups. Neonatal mortality did not differ between the groups. Cconclusions: Socioeconomic status was not a risk factor for sub-optimal birth weight in the studied population. Genetic and environmental factors were associated to sub-optimal weight and neonatal diseases. According to these data, this group of newborns should receive special attention from the health team.

    Full Text Available Abstract Introduction: The Kangaroo Mother Care (KMC method is a significant neonatal alternative that ensures better quality humanized care for preterm and low birth weight newborns. Objective: To analyze the immediate physiological effects of the kangaroo position in critically ill newborns. Methods: Open clinical trial with parallel interventions, involving preterm (up to 28 days old low or very low birth weight newborns (minimum weight of 1,250 grams of both sexes, that were clinically stable and undergoing enteral nutrition. The degree of respiratory distress was assessed and quantified using the Silverman-Anderson scoring system. Heart rate and peripheral oxygen saturation were collected using a pulse oximeter. Respiratory rate was determined by auscultation for one minute. The newborns were submitted to the kangaroo position once only, for 90 minutes. Results: Participants were 30 newborns, 56.7% of which were girls. Comparison of the variables before and after application of the kangaroo position using the Wilcoxon test showed a statistically significant reduction in respiratory rate (p = 0.02 and Silverman-Anderson score (p < 0.01. The remaining variables showed no significant differences: heart rate (p = 0.21, peripheral oxygen saturation (p = 0.26 and axillary temperature (p = 0.12. Conclusion: There was a decline in the respiratory rate and Silverman-Anderson score after application of the kangaroo position, while peripheral oxygen saturation, axillary temperature and heart rate remained stable.

    Full Text Available Abstract Background Recent studies have demonstrated that low and high birth-weight at birth are risk factors of developing diabetes. The aim of this study was to determine if the abnormal birth-weight is related with hyperinsulinemia and elevated index of the Homeostasis Model assessment for Insulin Resistance (HOMA-IR at birth, in at term newborns. Methods Newborns with gestational age between 38 and 41 weeks, products of normal pregnancies of healthy mothers aged 18 to 39 years, were eligible to participate. Small-for-gestational age (SGA and large-for-gestational age (LGA newborns were compared with appropriate-for-gestational (AGA age newborns. Incomplete or unclear data about mother’s health status, diabetes, gestational diabetes, history of gestational diabetes, hypertension, pre-eclampsia, eclampsia, and other conditions that affect glucose metabolism were exclusion criteria. Hyperinsulinemia was defined by serum insulin levels ≥13.0 μU/mL and IR by HOMA-IR ≥2.60.

    Today, it is acknowledged that smoking during pregnancy and/or the postnatal period has significant risks for a foetus and newborn child. This research examines the relationship between smoking only postnatally, both during pregnancy and postnatally, and the newborn sex, birth weight and breastfeeding. Total 664 women of randomly selected five primary healthcare centres between the dates 20 February 2010 and 20 July 2010 were included in the research. Statistical analyses were performed with SPSS for Windows 19.0 (Statistical Package for Social Sciences software package). Data were described as mean, standard deviation, percentages and Chi-square tests and backward stepwise logistic regression were analysed. It was found that the percentage of smoking women with daughters is 2.5 times higher than women with sons. Women who smoke are 3.9 times more likely to start feeding their baby with supplementary infant foods at 4 months or earlier than those who do not smoke. Finally, the risk of a birth weight under 2500 g is 3.8 times higher for maternal smokers. This study suggests that women who expect a girl smoke more heavily than those who expect a boy. The birth weight of maternal smokers' newborns is lower. Those women who smoke while breastfeeding start feeding their babies with supplementary infant foods at an earlier age.

    To obtain the low birth weight (LBW) rate, the very low birth weight (VLBW) rate, and gestational age (GA)-specific birth weight distribution based on a large population in Korea, we collected and analyzed the birth data of 108,486 live births with GA greater than 23 weeks for 1 yr from 1 January to 31 December 2001, from 75 hospitals and clinics located in Korea. These data included birth weight, GA, gender of the infants, delivery type, maternal age, and the presence of multiple pregnancy. The mean birth weight and GA of a crude population are 3,188 +/-518 g and 38.7+/-2.1 weeks, respectively. The LBW and the VLBW rates are 7.2% and 1.4%, respectively. The preterm birth rate (less than 37 completed weeks of gestation) is 8.4% and the very preterm birth rate (less than 32 completed weeks of gestation) is 0.7%. The mean birth weights for female infants, multiple births, and births delivered by cesarean section were lower than those for male, singletons, and births delivered vaginally. The risk of delivering LBW or VLBW infant was higher for the teenagers and the older women (aged 35 yr and more). We have also obtained the percentile distribution of GA-specific birth weight in infants over 23 weeks of gestation.

    Full Text Available Objective: Identification of variables that affect the risk of severe intraventricular hemorrhage (IVH in very low birth weight (VLBW newborns. Methods: Analytic case-control study, in a population consisting of all VLBW newborns admitted to the Neonatal Intensive Care Unit of a maternity hospital, between January 2002 and December 2007. The authors considered as cases all VLBW newborns with severe IVH (grade ≥ 3, and control all VLBW newborns without IVH. Independent variables included obstetric, perinatal and neonatal diagnosis and therapy. Bivariate analysis and multivariate logistic regression analysis were performed. Rresults: During this period, of the 864 VLBW newborns admitted to the Neonatal Intensive Care Unit, 9.7% had severe IVH. With bivariate analysis an association between severe IVH, gestational age and birth weight was found. Prenatal care and pre-eclampsia were associated with a decrease in the incidence of severe IVH. Amnionitis, being outborn, vaginal delivery, male gender, intubation in the delivery room, surfactant, hyaline membrane disease, pneumothorax, necrotizing enterocolitis (NEC perforation and oscillatory high frequency ventilation were associated with an increased incidence of severe IVH. By multivariate logistic regression, the variables associated with increased risk of severe IVH were: pneumothorax (OR = 3.8; 95%CI = 1.7-8.3, NEC with perforation (OR = 8.8; 95%CI = 1.7-45.0, vaginal delivery (OR = 2.0; 95%CI = 1.0-4.1 and high frequency ventilation (OR = 4.8; 95%CI = 1.3-17.3. The following were protective of severe IVH: gestational age (OR = 0.61; 95%CI = 0.52-0.72, patent ductus arteriosus treatment with indomethacin (OR = 0.26; 95%CI = 0.11-0.6 and fertility treatment (OR = 0.24; 95%CI = 0.06-0.94. Cconclusion: These data outline the importance of improvement of pre and neonatal care to reduce severe IVH.

    In Africa low birth weight (LBW) (birth weight. In 1000 Sudanese mothers with singleton births, anthropometric measurements (weight, height, mid-arm circumference) and newborn birth weight were taken within 24 hours of delivery. Furthermore, maternal education and socio-economic status were recorded. The effect of these maternal variables on gestational age and birth weight was investigated by receiver operating characteristic (ROC) curves and by multivariate logistic regression analysis. Although maternal height was significantly correlated (p = 0.002) with gestational age, we did not find maternal characteristics of value in determining the risk for preterm birth. Birth order was the strongest determinant of birth weight compared to other maternal characteristics. The LBW rate of first born babies of 12.2% was nearly twice that of infants of multiparous mothers. Maternal age and all maternal anthropometric measurements were positively correlated (p birth weight. A maternal height of birth weight, while the number of years of education was positively correlated with birth weight (p = 0.01). The LBW rate decreased from 9.2% for 12 years of education. Birth order and maternal height were found to be the most important maternal parameters which influences birth weight and the risk for LBW. The duration of maternal education and not social class was found to significantly affect the risk for LBW.

  1. Efficacy of prophylactic phototherapy for prevention of hyperbilirubinemia in very low birth weight newborns

    Full Text Available Background: Jaundice is a common clinical condition in newborn occurring in approximately 60% of term and 80% of preterm infants. Unconjugated hyperbilirubinemia is universally common in all preterm infants especially in newborns with very low biLth weight. Low birth weight and premature infants are at major risk for exaggerated hyperbilirubinemia that can lead to bilirubin encephalopathy. Significant heterogeneity in the approach to the treatment of jaundiced neonates exists throughout the world. Phototherapy is the most common treatment for neonatal hyperbilirubinemia and could be most effective in preventing the sequelae of hyperbilirubinemia if initiated prophylactically. This randomized clinical trial has been proposed with the objective of assessing the efficacy of prophylactic photo therapy in preventing significant rise of unconjugated hyperbilirubinemia in premature neonates weighing less than 1500 gram and therefore to decrease the need for exchange transfusion and finally to reduce hospital stay due to hyperbilirubinemia. Methods: This randomized controlled clinical trial enrolled sixty newborns with birth weight less than 1500 gram. They were divided into two groups: 1 Prophylactic group, in whom phototherapy was started within 24 hours of birth and continued for 7 days and 2 Control group in whom therapeutic phototherapy was started considering serum bilirubin level and other clinical condi­tions as per institutional guidelines. Mean value of total serum bilirubin (TSB, duration of phototherapy, the need for exchange transfusion and duration of hospital stay in both groups were analyzed.Results: The maximum mean TSB level in prophylactic group was observed on 7th day and in control group it was observed on 3rd day of life. The total serum bilirubin levels were significantly lower in the 3rd and 5th days of life in the prophylactic group in comparison to control group (P value 0.001. Total serum bilirubin level exceeded therapeutic

    To evaluate the predictive factors of birth weight (BW) of newborns of women with gestational diabetes mellitus (GDM). A cross-sectional study was performed among pregnant women with GDM treated in a public maternity unit, Brazil. We selected 283 pregnant women, with nutritional follow-up initiated till the 28th gestational week, singleton pregnancy, without chronic diseases and with birth weight information of the newborns. The predictive factors of BW were identified by multivariate linear regression. Mean maternal age was 31.2 ± 5.8 years; 64.4% were non-white; 70.1% were pre-gestational overweight or obese. Mean BW was 3234.3 ± 478.8 g. An increase of 1 kg of weight in the first and third trimesters increased BW by 21 g (p = 0.01) and 27 g (p = 0.03), respectively. Similarly, the other predictive factors of BW were pre-gestational body mass index (β = 17.16, p = 0.02) and postprandial plasma glucose in the third trimester (β = 4.14, p = 0.008), in the model adjusted by gestational age at delivery (β = 194.68, p gestational age at birth, and maternal pre-gestational and gestational anthropometric characteristics. Maternal glycaemic levels may also influence BW. The results may contribute to a review of prenatal routines for pregnant women with GDM. Copyright © 2018 Elsevier B.V. All rights reserved.

Methods: Descriptive prospective study in a nine-year period, between 1999 January 1st to 2008 January 1st. All the very low birth weight newborns were born in Dr. Alfredo da Costa Maternity, Lisbon, Portugal, were admitted to the Neonatal Intensive Care Unit and submitted to high frequency oscillatory ventilation with early lung volume optimization; these newborns were followed-up since birth and their charts were analyzed periodically until hospital discharge. Rresults: From a total population of 730 very low birth weight inborns, 117 babies died (16% and 613 survived (84%. The median of birth weight was 975 g and the gestational age median was 28 weeks. For the survivors, the median ventilation and oxygenation times were 3 and 18 days, respectively. The incidence of chronic lung disease was 9.5%, with nine newborns discharged on oxygen therapy. The incidence of intraventricular hemorrhage III – IV (total population group was 11.5% and the incidence of retinopathy of prematurity grade 3 or higher was 8.0%. Cconclusions: High frequency oscillatory ventilation with early lung volume optimization strategy reduced the need of respiratory support, and improved pulmonary and global outcomes in very low birth weight infants with respiratory distress syndrome.

    In low income countries, many low birth weight newborns often miss the chance for survival sooner or later. Others who survive would also face increased risks in later life. Though not adequately documented in Ethiopia, maternal factors pose the main risk. This study was aimed to estimate the proportion of low birth weight among term singletons without congenital malformations and factors associated with it in Wolaita Sodo town in South Ethiopia. We did a facility based survey involving 432 postpartum women with their term newborns. Data was collected through face to face interview from March to April in 2016. The outcome measure was newborn birth weight. Bivariate logistic regression was applied to look for crude associations. Multivariate logistic regression analysis was done to adjust for potential confounders to identify independent predictors. Adjusted Odds Ratio (AOR) and 95% confidence intervals (CI), and statistical significance at P low birth weight was 8.1% in the study area. Women who had less education (AOR = 6.23; 95% CI = 1.68, 23.1), house wives (AOR = 5.85; 95% CI = 1.40, 24.3) and not frequently consuming fruits during pregnancy (AOR 11.3; 95% CI = 1.98, 64.9) had a higher risk of having term low birth weight newborns. We documented a lesser odds of those from rural settings to have low birth weight newborns as compared to their counter urban equivalents (AOR = 0.06; 95% CI = 0.006, 0.6). Dietary counselling to pregnant mothers specific diet and nutrition including fruit diets in particular might contribute to reduce the risk of term low birth weight. Better education might have enabled women to prefer diets and their job engagements might also have capacitated them to decide on dietary preferences.

    Background: Low birth weight is a major public health problem in Pakistan. So there is a need for identification of its modifiable risk factors like periodontitis which will reduce its burden on the society. The objectives of the study were to find out the association between maternal periodontitis and low birth weight in new-borns of all gestational ages delivered in a tertiary care hospital of Abbottabad as well as to see the frequency of periodontitis severity in these subjects. Methods: A hospital-based matched case-control study was conducted among 160 postpartum mothers in Gynaecology/Obstetrics-B ward Ayub Teaching Hospital, Abbottabad. The 80 cases were mothers of low birth weight babies (<2,500 g), the 80 controls were mothers of normal weight babies (=2,500 g) matched with maternal age and gestational age. Data was collected through the hospital records, interview and a periodontal examination. Results: Periodontitis was more in the cases than in the controls (OR: 4.167, 95 percentage CI: 2.142-8.109, ρ=0.000). On multivariate logistic regression, periodontitis was found to be a significant independent risk factor for low birth weight (aOR: 3.173, 95 percentage CI: 1.429-7.047, ρ=0.005). Other significant risk factors were educational level (aOR: 3.408, 95 percentage CI: 1.452-7.996, ρ=0.005), socioeconomic status (aOR: 3.173, 95 percentage CI: 1.366-7.368, ρ=0.007), maternal nutrition (aOR: 3.071, 95 percentage CI: 1.392-6.778, ρ=0.005) and moderate/severe anaemia (aOR: 3.035, 95 percentage CI: 1.052-8.756, p=0.040). Conclusions: Periodontitis is found to be a strong, independent, and clinically significant risk factor for low birth weight. So periodontal therapy should form a part of the antenatal care of the pregnant women in Abbottabad. (author)

    The objectives of this study were to characterize noise and light levels for extremely low birth weight newborns throughout their stay in the NICU, evaluate factors influencing noise and light levels, and determine whether exposures meet recommendations from the American Academy of Pediatrics. Sound and light were measured inside the beds of extremely low birth weight newborns (n = 22) from birth to discharge. Measurements were recorded for 20 consecutive hours weekly from birth until 36 weeks' postmenstrual age, biweekly until 40 weeks, and every 4 weeks thereafter. Clinical variables including bed type and method of respiratory support were recorded at each session. Age-related changes in respiratory support and bed type explained the weekly increase of 0.22 dB in sound level and 3.67 lux in light level. Old incubators were the noisiest bed types, and new incubators were the quietest. Light levels were significantly higher in open beds than in incubators. The variations in noise and light levels over time were greatest for open beds. Noise and light levels were much less affected by respiratory support in incubators compared with open beds. A typical extremely low birth weight neonate was exposed to noise levels averaging 56.44 dB(A) and light levels averaging 70.56 lux during their stay from 26 to 42 weeks' postmenstrual age in the NICU. Noise levels were rarely within American Academy of Pediatrics recommendations (5.51% of the time), whereas light levels almost always met recommendations (99.37% of the time). Bed type and respiratory support explained differences in noise and light levels that extremely low birth weight newborns experience during their hospital stay. Noise levels exceeded recommendations, although evidence supporting those recommendations is lacking. Well-designed intervention studies are needed to determine the effects of noise reduction on the development of extremely low birth weight newborns.

    Full Text Available Abstract Background In Africa low birth weight (LBW ( Methods In 1000 Sudanese mothers with singleton births, anthropometric measurements (weight, height, mid-arm circumference and newborn birth weight were taken within 24 hours of delivery. Furthermore, maternal education and socio-economic status were recorded. The effect of these maternal variables on gestational age and birth weight was investigated by receiver operating characteristic (ROC curves and by multivariate logistic regression analysis. Results Although maternal height was significantly correlated (p = 0.002 with gestational age, we did not find maternal characteristics of value in determining the risk for preterm birth. Birth order was the strongest determinant of birth weight compared to other maternal characteristics. The LBW rate of first born babies of 12.2% was nearly twice that of infants of multiparous mothers. Maternal age and all maternal anthropometric measurements were positively correlated (p 12 years of education. Conclusion Birth order and maternal height were found to be the most important maternal parameters which influences birth weight and the risk for LBW. The duration of maternal education and not social class was found to significantly affect the risk for LBW.

    Full Text Available Abstract Objectives: to determine the prevalence of the most common morbidities in extremely low birth weight (ELBW infants hospitalized in a newborn intensive care unit (NICU and to evaluate the influence of these morbidities through the length of in-hospital stay. Methods: observational, longitudinal, prospective and analytical study in a high risk reference maternity NICU from Sergipe, realized with 158 ELBW infants admitted between March 2014 and April 2015. The analysis of the hospitalization time was realized through the Kaplan-Meier method. Results: the average weight of premature was 785,2g ± 138,2g. The gestational age vary from 22 to 35 weeks and the average was 26,8 weeks. Of those admitted at NICU, sixty three (39,9% were discharged and 95 (60,1% died. The time of hospitalization was influenced for morbidities as: patent ductus arteriosus (PDA, intraventricular hemorrhage and sepsis. Acute respiratory distress syndrome was the most common complication (157 - 99,4%. The incidence of persistent arterial duct, intraventricular hemorrhage, sepsis, hypothermia, hypoglycemia and retinopathy of prematurity was 39,2%, 17,1%, 32,3%,50,3%, 52,3% e 16,6% respectively. Conclusions: the morbidities from respiratory tract, cardiac, neurological and infectious were the most prevalent, whilst PDA, intraventricular hemorrhage and sepsis were the morbidities that significantly influenced the time of hospitalization.

    Epidemiological research has identified a relationship between maternal physical activity, early nutrition and infant birth weight with likelihood of developing future diseases. The aim of the study was to determine a relationship between gestational weight gain and physical activity during pregnancy to the nutritional status of newborns. The presented study was conducted in the period from February 2010 until November 2012 in the gynecological and obstetric clinics in Warmińsko-Mazurskie voivodeship with various levels of reference. The research subjects included 510 women in the puerperal period aged 18-36. The scope of the research included an assessment of the selected anthropometric parameters of both pregnant women (body mass, height, BMI, gestational weight gain) and newborns (infant birth weight, infant length, Ponderal Index), as well as an analysis of the connections between the gestational weight gain, physical activity during pregnancy and anthropometric parameters of newborns. In the study group there was a significant percentage of women characterised by an inactive lifestyle and excessive gestational weight gain. There were significantly higher neonatal birth anthropometric parameters in women with abnormal excessive gestational weight gain than in women with normal and inappropriate - low gestational weight gain. The highest percentage of women with appropriate weight gain was observed in the group of women who are physically active, although this requires confirmation in larger population. Our studies have not shown statistically significant differences between the gestational weight gain and nutritional status of newborns in relation to the level of physical activity of pregnant women.

    Life evolved in an environment filled with a wide variety of ionizing and non-ionizing radiation. It was previously reported that medical exposures to pregnant women increases the risk of low birth weight. This study intends to investigate the relationship between exposure to ionizing and non-ionizing radiation and the risk of low birth weight. One thousand two hundred mothers with their first-term labor (vaginal or cesarean) whose newborns' history had been registered in neonates' screening program in Shiraz were interviewed and surveyed. Data collection was performed by the assessment of mother's history of radiography before and during pregnancy, physical examination of the mother for height and weight and weighing and examining the newborn for any diagnosis of disease and anomalies. There were no statistical significant differences between the mean weight of newborns whose mothers had been exposed to some common sources of ionizing and non-ionizing radiations such as dental or non dental radiographies, mobile phone, cordless phone and cathode ray tube (CRT) and those of non-exposed mothers. The findings of this study cast doubt on previous reports, which indicated that exposure to ionizing radiation during pregnancy increased the risk of low birth weight.

    Full Text Available Low birth weight (LBW and preterm birth are one the most important causes of death in the world and therefore are considered as one of the major health problems. Global statistics demonstrates an increase in the prevalence of low birth weight in the developing countries. Low birth weight infants are exposed to complications such as major neurosensory impairements, cerebral palsy, cognitive and language delays, neuromotor developmental delay, blindness and hearing loss, behavioral and psychosocial disorders, learning difficulties and dysfunction in scholastic performances. The majority of infant's death and developmental disorders were due to disorders relating to prematurity and unspecified low birth weight. Infants weighing less than 2500 g, is a major determinant of both neonatal and infant mortality rates and, together with congenital anomalies (e.g., cardiac, central nervous system, and respiratory, contributes significantly to childhood morbidity. Various studies indicate that low birth weight infants are suffering from physiological and psychosocial disabilities, two to three times more than the other children. At school age, preterm and low birth weight infants have poorer physical growth, cognitive function, and school performance. These disadvantages appear to persist into adulthood and therefore have broad implications for society. Although the survival rates have increased dramatically and the incidence of morbidities has decreased, the complications are still considered to be associated with economical and social burdens. Most children with Low birth weight suffer from multiple disabilities. Therefore, they need special and consistent care. On demand of reducing the infant mortality rate, the need to decrease the complications in low birth weight and preterm infants should be considered by the policy makers in health care system. In this review article, we assessed current evidences on developmental outcomes of low birth weight and

    Low birth weight is associated with exposure to air pollution during pregnancy. The purpose of this study was to evaluate whether null polymorphisms of Glutathione S-transferases (GSTs), specifically GSTM1 and GSTT1 genes in infants or mothers, modify the association between high exposures to household air pollution (HAP) from cooking fires and birth weight. Pregnant women in rural Guatemala were randomized to receive a chimney stove or continue to use open fires for cooking. Newborns were measured within 48 h of birth. 132 mother-infant pairs provided infant genotypes (n=130) and/or maternal genotypes (n=116). Maternal null GSTM1 was associated with a 144 g (95% CI, -291, 1) and combined maternal/infant null GSTT1 was associated with a 155 g (95% CI, -303, -8) decrease in birth weight. Although there was a trend toward higher birth weights with increasing number of expressed GST genes, the effect modification by chimney stove use was not demonstrated. Copyright © 2014 Elsevier Inc.

    Full Text Available Objective: Our aim was to assess the association of perinatal factors with the early neonatal mortality in newborns with very low (VLBW and extremely low birth weight (ELBW.Methods: The statistical data was carried out, that is analysis of 17 perinatal factors of 28 newborns with an ELBW with gestation of 23–27 weeks and 18 newborns with a VLBW with gestation of 28–32 weeks, who died in the first 7 days of life. The comparison group consisted of 25 newborns with an ELBW and 56 children with a VLBW with gestation of 25–27 and 28–32 weeks, respectively, who survived the early neonatal period. The association of risk factors with the early neonatal mortality was assessed by means of a multiple-factor logistic regression analysis. A critical p error level was set equal to 0.05. Results: In newborns with a VLBW the increased risk of the early neonatal mortality depended on a gestation term (OR 4.40, 95% CI 1.56–11.71; р = 0.002 and emergency Caesarean section (OR 7.48, 95% CI 1.28–43.74; р = 0.008. A vaginal birth increased the survival chance (OR 0.12, 95% CI 0.01–0.86; р = 0.032. Newborns with an ELBW had the following factors of the increased risk of the early neonatal mortality: gestational age (OR 2.86, 95% CI 1.06–7.73; р = 0.038, Apgar score at the 5th minute (OR 1.91, 95% CI 0.99–3.69; р = 0.050 and presence of chorioamnionitis (OR 5.45, 95% CI 1.0–29.53; p = 0.048. An elective Caesarean section increased the survival chance (OR 0.02, 95% CI 0.001–0.44; p = 0.048. Conclusion: Summarizing the obtained data, we can conclude that besides a gestational age the risk of early neonatal mortality in newborns with a VLBW may be increased due to the emergency Caesarean section, with an ELBW — due to a low Apgar score at the 5th minute and the presence of mother's chorioamnionitis. A vaginal birth in newborns with a VLBW and an elective Caesarean section in children with an ELBW increase survival chances.

    HELLP syndrome is a serious hypertensive disorder of pregnancy with important neonatal problems in the newborn. The objective of this work was to determine the characteristics of these infants and its neonatal evolution. A retrospective observational study of all newborns of mothers with HELLP syndrome born in a university hospital between January 1, 2008 and December 31, 2013 was carried out. Thirty-three infants from 28 pregnancies (five twin gestations) were studied. A descriptive and comparative analysis between groups and a multivariate analysis of factors associated with mortality in the series took place. Of 33 newborns studied (2.2 newborns/1,000 infants total), two were stillbirths (6.1% of the total) and four died after birth (12.9% of live neonates) with overall perinatal mortality of 18.2%. Pregnancies in 28 infants ended before 37 weeks (84.8%) and 11 pregnancies ended before week 32 (33.3%). Seven infants weighed<1500g (four weighed <1000g). Of the 31 live births, 13 infants were in a <10th percentile weight for gestational age (41.9%), 20 needed neonatal resuscitation (64.5%) and 14 had leukopenia at birth (45.2%). In the final logistic regression, neonatal mortality was associated with extreme prematurity regardless of underweight, leukopenia and/or need for neonatal resuscitation. Children of mothers with HELLP syndrome have a high mortality associated with extreme prematurity, independent of the presence of leukopenia, low weight for gestational age and need for neonatal resuscitation.

    Objective: This study explored the association between air pollution exposure and birth weight by using the multilevel linear model, after controlling related meteorological factors and individual differences of both mothers and babies. Methods: Women of childbearing age who were pregnant in Xi'an from 2010 to 2013, were selected as objects of this study. Multistage random sampling method was used to select 4 631 subjects followed by a self-designed questionnaire survey. Data related to quality of air and meteorology were gathered from routine monitoring system. Gestational age and date of birth, together with the average levels of air pollution were calculated for each trimester on each mother, and then the impact of air pollution on birth weight was assessed. A multilevel linear model was employed to investigate the association between the levels of exposure to air pollution by birth weight. Confounding factors were under control. We established three models in this study: Model 1 which involving the variable of air pollution exposure. Model 2 was adjusted for variables in Model 1 plus some other individual differences of both mother and baby. Model 3 was adjusted for variables in Model 2 plus meteorological factors. Results: There were significant differences seen in birth weight within the subgroups of gender, gestational age, mother's reproductive age, maternal education, residential areas and family incomes ( P 0.05). Data from Model 3 indicated that a decrease of 13.3 g(10.9 g in Model 2) and 6.6 g (5.9 g in Model 2) in birth weight that were associated with an increase of 10 μg/m(3) in the average level of NO(2) and PM(10) during the second trimester; A decrease of 13.7 g (9.8 g in Model 2) in birth weight was associated with an increase of 10 μg/m(3) in the average level of NO(2) during the third trimester. Conclusion: After controlling for meteorological factors, the levels of exposure to NO(2) and PM(10) during the second trimester and NO(2) during the

    The aim of this study was to assess the relationship between mother-child GSTM1, GSTT1 gene polymorphisms, maternal weight gain, maternal bioimpedance parameters and newborn's weight, in order to identify the factors that influence birth weight. We performed a cross-sectional study on 405 mothers and their newborns, evaluated in an Obstetrics and Gynecology Tertiary Hospital from Romania. Newborns whose mothers had the null genotype of GSTT1 gene polymorphism were more likely to gain a birth weight of >3 kg, compared to newborns whose mothers had the T1 genotype (odds ratio - OR: 2.14, 95% confidence interval - CI: [1.03; 4.44]). Also, the null genotype of GSTM1 gene polymorphism in both mothers and newborns was associated with a higher birth weight. Gestational weight gain was positively associated with newborn's birth weight (pmother's fat mass (%) and basal metabolism rate were also independent factors for a birth weight of more than 3 kg (p=0.006 and p=0.037). The null genotype of GSTT1 gene polymorphism in mothers and the null genotype of GSTM1 in mothers and newborns had a positive effect on birth weight. Also, increased maternal fat mass and basal metabolism rate were associated with increased birth weight. We conclude that maternal GSTM1÷GSTT1 gene polymorphisms present an impact on birth weight, being involved in the neonatal nutritional status. The clinical relevance of our study is sustained by the importance of identifying the factors that influence birth weight, which can be triggers for childhood obesity.

    Full Text Available Study in order to know the results of prenatal care related to clinical complications of pregnancy, newborn’s low birth weight and prematurity in the context of the users of the service. Descriptive, exploratory research with quantitative approach developed with 305 users who underwent prenatal care in primary care in the city of Mossoró-RN. The data collection occurred from the application of a validated questionnaire, the IPR-PRENATAL index. The results indicate that over 50% of pregnant women had some type of complication during their pregnancy process, among intercurrent diseases in pregnancy, and experienced by users, the urinary tract infection was the most prevalent (28.0%, followed by anemia (19.3% and hypertension (15.7%. Hypertension and anemia were the only events that interfere with the newborn’s weight, which showed that the existence of complications contributes in three times to the occurrence of low birth weight. In this sense, the quality of prenatal care can minimize that type of complication.

It was prospectively shown that 111 (100%) of the surviving infants could be regularly followed in a newborn follow-up clinic to provide health maintenance, developmental assessment and support. Compared with reports from other developing countries, VLBW infants at our center had higher survival rates. Compared to developed countries, survival rate was lower, especially for extremely very low birth weight infants. There is interaction between birth weight and survival rate. Among selected neonatal outcomes, chronic lung disease, threshold retinopathy, severe intraventricular hemorrhage (IVH > or = grade III) and nosocomial infection rates at this center were comparable with some reports from developed nations.

    The influence of previous interruptions, miscarriages and IUFD on the IUGR and preterm rate as well as on the somatic staging (gestational age and birth weight) of the new born is a subject of controversial discussion in the literature. The present paper attempts to quantify these risks of the medical history. 2 282 412 singleton pregnancies of the period 1995 to 2000 were evaluated from the German Perinatal Database. For the analysis 1 065 202 pregnancies (46.7 %) of those mothers without any live birth in the medical history were assessed. To exclude any influence from previous abortions patients with previous miscarriages and IUFDs were excluded. The control collective were new borns whose mothers had suffered neither from miscarriages nor from abortions or IUFD. Previous interruptions, miscarriages and IUFD influence the rate of new borns with low birth weight and increase the rate of prematurity. With increasing numbers of isolated or combined risks in the medical history, the rate of newborns with a low birth weight or with prematurity is increased. The lowest risk was found after one interruption, the highest rate with two or more IUFDs. Interruptions, miscarriages or IUFD are not risk factors for IUGR or SGA. Previous interruptions, miscarriages and IUFD are relevant risk factors for prematurity and are related with low birth weight of the new borns. Pregnant women with such risk factors have to been considered as risk pregnancies and need intensive surveillance.

    Full Text Available ABSTRACT Objective To investigate the association between physical intimate partner violence and low birth weight. Methods This cross-sectional study included 604 children with approximately 30 days of age who visited four primary health care units in the city of Rio de Janeiro , Brazil, for the second dose of hepatitis B vaccine. Children with a birth weight below 2.500 g were considered underweight. Information regarding physical intimate partner violence was obtained by the Portuguese version of the Conflict Tactics Scale. The study investigated the 12 months prior to interview. Physical intimate partner violence was analyzed as a dichotomous variable and cumulatively. Associations between physical intimate partner violence and low birth weight were verified by logistic regression models based on crude and adjusted odds ratios and their respective 95% confidence intervals. Results Some (7.1% babies were born underweight, and 33.6% of the mothers had been exposed to physical intimate partner violence. Physical intimate partner violence was significantly associated with low birth weight (OR=3.69; 95%CI=1.57-8.66. Notably, the odds of low birth weight increase with the severity of violence. Conclusion These findings draw attention to the consequences of physical intimate partner violence on the nutritional status of newborns and emphasize the need of greater attention during prenatal care to improve women's quality of life and to reduce the rate of low birth weight.

    To determine the extent the World Health Organization (WHO) guidelines on the care of Low Birth Weight (LBW) newborns are followed in Pakistani hospitals and analyze any difference in policy compliance between different hospitals. Study Design: Descriptive analytical study. Place and Duration of Study: Data was collected from five tertiary care hospitals, one each from Peshawar, Lahore, Quetta, Karachi and Islamabad, from January to June 2012. Methodology: LBW newborns data derived from medical records was used. It was collected using a questionnaire, which encompassed the recent WHO recommendations for feeding of LBW. Twenty questionnaires were collected from each hospital. STATA 11.0 was used to analyze the data. Results: Fifty seven LBW newborns (57%) were fed with mother's own milk, and 9 (9%) were fed on donor human milk. Forty four newborns (44%) were initiated breast feeding within the first hour after birth. Most of the babies not able to be breast fed were fed with intra gastric tube. Feeding practices varied markedly across hospitals, ranging from one hospital where all newborns were fed formula milk to one where all were fed breast milk. Conclusion: The WHO guidelines were only partially implemented, with significant differences between hospitals in level of implementation of recommended practices. Given the benefits expected from the application of the guidelines, efforts should be made for the establishment and promotion of a single national policy for LBW feeding that follows the WHO new guidelines and streamlines the LBW feeding practices across the country.

    Current literature has been inconsistent in demonstrating that minimizing the duration of mechanical ventilation in very-low-birth-weight (VLBW) newborns reduces lung damage. To determine if introduction of bubble nasal CPAP (bnCPAP), early surfactant treatment, and rapid extubation (combined bnCPAP strategy) in our community-based neonatal ICU reduced bronchopulmonary dysplasia (BPD). This was a 7-year retrospective,single-institution review of respiratory outcomes in 633 VLBW babies before and after introduction of the combined bnCPAP strategy. Coincident changes in newborn care were taken into account with a logistic regression model. The average percentage of VLBW newborns with BPD decreased to 25.8% from 35.4% (P = .02), reaching a minimum in the last post-bnCPAP year of22.1% (P = .02). When other coincident changes in newborn care during the study years were taken into account, VLBW babies in the post-bnCPAP years had a 43% lower chance of developing BPD(P = .003, odds ratio 0.43, 95% CI 0.25– 0.75). Decreases occurred in mechanical ventilation and the percentage of infants discharged on diuretics and on supplemental oxygen. Among the subset of extremely-low-birth-weight newborns, improved respiratory outcomes in the post-bnCPAP years,as compared to outcomes in the pre-bnCPAP years, included an increase in the percentage alive and off mechanical ventilation at 1 week postnatal age (P < .001), a more rapid extubation rate(P < .03), a decrease in the median days on mechanical ventilation (P = .002), and a decrease in the percentage with BPD plus died (P = .01). Post-bnCPAP extremely-low-birth-weight babies had a statistically significant decrease in retinopathy of prematurity, an increase in low-grade intraventricular hemorrhage, and a decrease in ductal ligations. A combined BnCPAP strategy may contribute to a reduction of BPD, after adjusting for concurrent treatments.

    To determine if community-based, low-cost interventions during third trimester of pregnancy can reduce the incidence of low birth weight babies. In a case control study, 290 pregnant women from a slum area were registered in the beginning of third trimester of pregnancy and provided full antenatal care comprising fortnightly check up, one IFA tablet daily, counseling for minimum one-and-a-half hour post-lunch rest in left lateral position, additional diet to ensure minimum 2,200 kcal per day, and management of clinical conditions, if any. An equal number of pregnant women belonging to the same slum area were registered as control who received routine antenatal services from the existing health care facilities. The birth weight of the babies in the two groups were recorded and compared. Test of significance and correlation coefficient were applied to the data. Mean birth weight of the babies of the Subjects was 2.76 kg (SD 0.39) compared to mean birth weight of 2.57 kg (SD 0.36) of the babies in the Control group. Incidence of low birth weight babies among subjects who consumed minimum 2,400 kcal per day, had one-and-a-half hour post-lunch rest in left lateral position and who consumed one tablet of IFA (100 mg iron and 5 mg folic acid) per day during the last trimester of pregnancy was lower (17.6 %) as compared with women in the Control group (36.2 %). The difference in the mean birth weight of newborns of the two groups was statistically significant (t = 2.52, p < 0.01). Incidence of low birth weight babies can be significantly reduced by providing simple, low-cost care to pregnant women during the last trimester of pregnancy in the community setting.

    Excess adiposity and adiposity-related inflammation are known risk factors for cardiovascular disease in adults; however, little is known regarding the determinants of adiposity-related inflammation at birth. The aim of this study was to investigate the association between maternal pre-pregnancy BMI and newborn adiposity and inflammation. Paired maternal (28-week gestation) and infant (umbilical cord) blood samples were collected from a population-derived birth cohort (Barwon Infant Study, n = 1074). Data on maternal comorbidities and infant birth anthropomorphic measures were compiled, and infant aortic intima-media thickness was measured by trans-abdominal ultrasound. In a selected subgroup of term infants (n = 161), matched maternal and cord lipids, high-sensitivity C-reactive protein (hsCRP) and maternal soluble CD14 were measured. Analysis was completed by using pairwise correlation and linear regression. Because of their non-normal distribution, pathology blood measures were log transformed prior to analysis. Maternal pre-pregnancy BMI was positively associated with increased birth weight (mean difference 17.8 g per kg m -2 , 95% CI 6.6 to 28.9; p = 0.002), newborn mean skin-fold thickness (mean difference 0.1 mm per kg m -2 , 95% CI 0.0 to 0.1; p pregnancy BMI, 95% CI 0.6 to 7.7%, p = 0.02), but not cord blood soluble CD14. Inclusion of maternal hsCRP as a covariate attenuated the associations between pre-pregnancy BMI and both newborn skin-fold thickness and cord blood hsCRP. Higher maternal pre-pregnancy BMI is associated with increased newborn adiposity and inflammation. These associations may be partially mediated by maternal inflammation during pregnancy. © 2016 World Obesity Federation.

This was a retrospective observational cohort study; 374 infants born prematurely or having low-birth-weight were included to assess household socio-demographic factors, maternal and obstetric history, delivery characteristics and complications and follow-up until 40 weeks post-conception age. There was a high prevalence of teenage pregnancy (17.5 %) and in women older than 35 years (12.6 %), unwanted pregnancy (40.6 %), low quality and poor availability of food in families, complications such as preeclampsia, infection and premature rupture of membranes, 1,969 grams average birth weight, 2,742.9 grams average weight on discharge and 22 grams average weight gain per day. It was found that KMP methodology substantially improved the mothers' psychological aspects and health status and the newborns' prognosis and led to stabilising body temperature and weight gain rate while decreasing risks of complications and nosocomial infection. It also lowered health care costs and shortened hospital stay.

    The development of less invasive ventilatory strategies in very-low-birth-weight (VLBW) preterm newborns has been a growing concern in recent decades. This study aimed to measure differences in the clinical progression of preterm newborns using two distinct periods in a university hospital: before and after using underwater bubble continuous positive airway pressure (ubCPAP). This is a retrospective study of VLBW preterm newborns with gestational ages less than or equal to 32 weeks admitted to the neonatal intensive care unit. The time series was divided into two groups: a pre-CPAP group ( n = 45) and a post-CPAP group ( n = 40). The post-CPAP group had fewer resuscitations, required fewer surfactant doses, spent fewer days on mechanical ventilation, and demonstrated less of a need for fraction of inspired oxygen > 30%. UbCPAP is an easy to use, minimally invasive, and effective ventilatory strategy for VLBW preterm newborns that can be used in environments with limited resources. Thus, adopting this simple strategy as part of a service organization and health policy can positively impact outcomes.

    Full Text Available Background. Low birth weight is the single most important factor that determines the chances of child survival. A recent annual estimation indicated that nearly 8 million infants are born with low birth weight in India. The infant mortality rate is about 20 times greater for all low birth weight babies. Methods. A matched case–control study was conducted on 130 low birth weight babies and 130 controls for 12 months (from August 1, 2007, to July 31, 2008 at the Central Referral Hospital, Tadong, East District of Sikkim, India. Data were analyzed using the Statistical Package for Social Sciences, version 10.0 for Windows. Chi-square test and multiple logistic regression were applied. A P value less than .05 was considered as significant. Results. In the first phase of this study, 711 newborn babies, borne by 680 mothers, were screened at the Central Referral Hospital of Sikkim during the 1-year study period, and the proportion of low birth weight babies was determined to be 130 (18.3%. Conclusion. Multiple logistic regression analysis, conducted in the second phase, revealed that low or middle socioeconomic status, maternal underweight, twin pregnancy, previous history of delivery of low birth weight babies, smoking and consumption of alcohol during pregnancy, and congenital anomalies had independent significant association with low birth weight in this study population.

    To describe an immobility reaction (IR) that was not previously reported at or immediately after birth in human newborns. We analyzed 31 videos of normal term vaginal deliveries recorded from Time 0 of birth defined as the as the moment that lies between the birth of the thorax and the pelvis of the infant. We searched for perinatal factors associated with newborn's IR. IR at birth was observed in 8 of the 31 newborns. The main features of their behavior were immobilization, frozen face, shallow breathing and bradycardia. One of the 8 newborns had sudden collapse 2h after birth. We found significant relationships between maternal prenatal stress (PS) and IR (p=.037), and a close to significant one between infants' lividness at Time 0 and IR (p=.053). The first breath of the 31 newborns occurred before and was not associated with the first cry (psyndrome. This first report of an IR reaction at birth in human infants could open up new paths for improving early neonatal care. Further research is needed for maternal PS, stress hormones, umbilical cord blood pH measurements in IR newborns. The challenge of education and support for parents of IR newborns is outlined.

    This study aimed to determine the health-related quality of life (HRQoL) in mothers of 5-year-old very low birth weight (VLBW) and normal birth weight (NBW) children, with a focus on the role of stress. This cohort study is ancillary to the Newborn Lung Project. A telephone interview collected information on symptoms of stress and HRQoL from 297 mothers of VLBW children and 290 mothers of NBW children who were enrolled in the Newborn Lung Project Statewide Cohort Study. Staged multiple regression analyses were used to evaluate the relationship between caregiver status and maternal HRQoL and the role stress played in this relationship. Additional multiple regression analyses were also used to evaluate the correlates of poor maternal HRQoL among VLBW mothers. Mothers of VLBW children experienced worse physical and mental HRQoL than mothers of NBW children. Adjusted analyses showed that physical HRQoL was significantly different between these mothers (β: -1.87, P = 0.001); this relationship was attenuated by maternal stress. Among the mothers of VLBW children, stress significantly contributed to adverse HRQoL outcomes when children were aged five. Child behavior problems at the age of two were also associated with worse subsequent maternal mental HRQoL (β: -0.18, P = 0.004), while each week of neonatal intensive care unit stay was associated with worse physical HRQoL (β: -0.26, P = 0.02). Caring for a VLBW child is negatively associated with the HRQoL of mothers; this relationship might be, in part, explained by maternal stress. Addressing maternal stress may be an important way to improve long-term HRQoL.

    Anaemia is commonly found in Pakistan especially in pregnant women and children of low socio-economic classes. Malnutrition and anaemia in pregnancy is also associated with impaired foetal and infant health. The pregnant women (n=102) in their third trimester of pregnancy without any obstetrical complications were the subjects for this study and 53.9% of them were anaemic with haemoglobin levels less than 11 g/dl. They were treated with either iron alone (100 mg/day), supplemented with folic acid (10 mg/day) or with folic acid (10 mg/day), vitamin B{sub 12} (2{mu}g/day) and vitamin C (140 mg/day) for 4 weeks. The biochemical parameters were repeated after 4 weeks of treatment and an improvement was observed when iron was supplemented with folic acid. The effect of malnutrition and anaemia of pregnant moment was assessed on the birth weights of their newborns in 124 women. The newborns were divided in to 3 groups i.e. Small for age (< 2.5 Kg), average birth weight (2.5 - 3.5 Kg) and large for age (> 3.5 Kg). The dietary history indicated a low intake of energy, protein and iron in mothers of small infants. On the basis of biochemical parameters it was concluded that the mothers were malnourished and anaemic which was more evident in mothers of small infants. The role of malabsorption was studied in 42 children suffering from malnutrition and anaemia and they were divided into 5 groups, i.e. fibrocystic disease of the pancreas. (n=9), coeliac disease (n=17), lactose intolerance (n=5), PEM (n=5) and non-specific diarrhea (n=6) on the basis of history, clinical impression and biochemical findings. Xylose and lactose tolerance tests were performed after oral dose of xylose or lactose respectively. The various biochemical indices studied indicate that malabsorption plays an important role in malnutrition and anaemia. (abstract only).

    Full Text Available OBJETIVO: Conhecer a evolução do peso ao nascer e a mortalidade hospitalar de nascidos vivos em maternidade de Campinas, SP. MÉTODOS: Foram estudados 215.435 nascimentos ocorridos em maternidade do Município de Campinas, SP, de 1975 a 1996. As informações foram coletadas de livros de registro e relatórios de assistência médica. Foram analisados os óbitos ocorridos antes da alta hospitalar, independentemente da idade. Para a análise dos dados, utilizou-se o programa Epi Info 6.01. RESULTADOS: O baixo peso se manteve próximo a 9% desde os anos 70, concentrando82% dos óbitos hospitalares em 1996. O peso insuficiente foi observado em 24% dos nascidos vivos. Em 1975, 13,3% dos nascidos com peso entre 1.000 g e 1.499 g sobreviveram e 73,8% dos nascidos com peso entre 1.500 g e 1.999 g. Em 1996, a sobrevida foi 69,1% e 87,7%, respectivamente. Houve grande diminuição do número de óbitos especialmente na faixa de 1.000 g a 1.499 g (de 867 para 309 por mil nascidos vivos, redução de 64,5% e de 1.500 g a 1.999 g (de 264 para 123 por mil nascidos vivos, redução de 53,4%. A mortalidade hospitalar entre aqueles de peso abaixo de 1.000 g permaneceu entre 78,9% e 100,0%, mesmo nos anos 90. Observou-se queda da mortalidade hospitalar de 17 para 11 por mil nascidos vivos. CONCLUSÕES: Não houve modificação na distribuição do peso ao nascer, a despeito deavanços apresentados por Campinas. Contudo, observou-se queda da mortalidade hospitalar. Outros estudos são necessários para compreender esse perfil.OBJECTIVE: To assess the trend of birth weight and hospital mortality rate of newborns, in a maternity hospital of Campinas, SP.

    Purpose This study aimed to: (1) determine the health-related quality of life (HRQoL) in mothers of five year old very low birth weight (VLBW) and normal birth weight (NBW) children; (2) determine what extent stress mediates the relationship between case status and maternal HRQoL; and (3) examine the pre-pregnancy, pregnancy, birth, and child health-related factors in predicting maternal HRQoL among mothers of five year old VLBW children. Methods A telephone interview was administered to 297 mothers of VLBW children and 290 mothers of NBW children who were enrolled in the Newborn Lung Project Statewide Cohort Study. Results Mothers of VLBW children experienced worse physical and mental HRQoL than mothers of NBW children (52.8 versus 55.3 points, p<0.0001, and 48.9 versus 50.5 points, p=0.02, respectively). Adjusted analyses showed that maternal mental HRQoL was similar between cases and controls while physical HRQoL when children were age five was significantly different between cases and controls (Beta:−2.02, p=0.0006); this relationship was mediated by maternal stress. Among mothers of VLBW children, stress significantly contributed to adverse HRQoL outcomes when children were age five. Child behavior problems at age two were also associated with worse subsequent maternal mental HRQoL (Beta: −1.8 per SD, p=0.004), while each week of neonatal intensive care unit stay was associated with worse physical HRQoL (Beta: −0.26, p=0.02). Conclusions While caring for a VLBW child negatively impacts the HRQoL of mothers, this relationship was partially explained by maternal stress. Addressing maternal stress may be an important way to improve long-term HRQoL. PMID:22161725

    Anaemia is commonly found in Pakistan especially in pregnant women and children of low socio-economic classes. Malnutrition and anaemia in pregnancy is also associated with impaired foetal and infant health. The pregnant women (n=102) in their third trimester of pregnancy without any obstetrical complications were the subjects for this study and 53.9% of them were anaemic with haemoglobin levels less than 11 g/dl. They were treated with either iron alone (100 mg/day), supplemented with folic acid (10 mg/day) or with folic acid (10 mg/day), vitamin B 12 (2μg/day) and vitamin C (140 mg/day) for 4 weeks. The biochemical parameters were repeated after 4 weeks of treatment and an improvement was observed when iron was supplemented with folic acid. The effect of malnutrition and anaemia of pregnant moment was assessed on the birth weights of their newborns in 124 women. The newborns were divided in to 3 groups i.e. Small for age ( 3.5 Kg). The dietary history indicated a low intake of energy, protein and iron in mothers of small infants. On the basis of biochemical parameters it was concluded that the mothers were malnourished and anaemic which was more evident in mothers of small infants. The role of malabsorption was studied in 42 children suffering from malnutrition and anaemia and they were divided into 5 groups, i.e. fibrocystic disease of the pancreas. (n=9), coeliac disease (n=17), lactose intolerance (n=5), PEM (n=5) and non-specific diarrhea (n=6) on the basis of history, clinical impression and biochemical findings. Xylose and lactose tolerance tests were performed after oral dose of xylose or lactose respectively. The various biochemical indices studied indicate that malabsorption plays an important role in malnutrition and anaemia. (abstract only)

    With the ending of one-child policy since 2015, the number of newborns are expected to increase in China, where people are surviving from pool air quality. Air pollutants, especially PM2.5 have been confirmed as a top risk factor to cause birth defects including low birth weight (LBW). Motivated by the increasing demands of the newborns for cleaner air in China, we conducted the first national risk assessment study on LBW cases caused by PM2.5. We combined county-level PM2.5 concentrations in 2013-2015 and demographic data (including population counts, birth rates and etc.), province-level baseline incidences of LBW and multiple reference safety concentrations (0 μg/m3, WHO air quality guidelines and interim targets) to estimate the number of PM2.5-associated LBW in 31 provinces. The uncertainty was quantified using Monte Carlo simulations. Based on our results, in 2013 among 334,781 (95% CI: 313,024-344,568) cases of LBW, 122,684 (95% CI: 53,153-173,846, account for 37% of the total LBW) were attributed to PM2.5, when assuming the reference safety concentration as 0 μg/m3; while 53,917 (95% CI: 22,851-82,195, account for 16% of the total LBW) cases of LBW could have been protected, if the air quality met WHO WHO interim target-3, 35 μg/m3. Among 31 provinces, PM2.5-associated LBW were mostly distributed in Hebei (12.99%, 95% CI: 12.42%-17.30%), Henan (9.75%, 95% CI: 9.11%-13.50%) and Guangdong (8.60%, 95% CI: 6.98%-9.42%). During 2013 to 2015, air quality in China was reported to be improved by implement of emission-reduction policies. Similarly, we found significantly decreasing trends of infants weighted concentrations of PM2.5 in most heavily polluted areas, which protected 12,201 (95% CI: 4,749-20,503) and 24,637 (95% CI: 9,619-39,821) PM2.5-associated LBW in 2014 and 2015, account for 3.64% (95% CI: 1.46%-6.21%) and 7.36% (95% CI: 2.93%-12.07%) of that in 2013, respectively. The uncertainty of this study was mainly contributed by that in epidemiology

    The present study had 2 objectives, first, to investigate possible relationships between increased gestational weight gain and demographic, clinical, paraclinical, genetic, and bioimpedance (BIA) characteristics of Romanian mothers, and second, to identify the influence of predictors (maternal and newborns characteristics) on our outcome birth weight (BW).We performed a cross-sectional study on 309 mothers and 309 newborns from Romania, divided into 2 groups: Group I-141 mothers with high gestational weight gain (GWG) and Group II-168 mothers with normal GWG, that is, control group.The groups were evaluated regarding demographic, anthropometric (body mass index [BMI], middle upper arm circumference, tricipital skinfold thickness, weight, height [H]), clinical, paraclinical, genetic (interleukin 6 [IL-6]: IL-6 -174G>C and IL-6 -572C>G gene polymorphisms), and BIA parameters.We noticed that fat mass (FM), muscle mass (MM), bone mass (BM), total body water (TBW), basal metabolism rate (BMR) and metabolic age (P mothers with high GWG. BW was positively correlated with mothers' FM (P G polymorphism was higher in the control group (P = 0.042).We observed that high GWG may be an important predictor factor for the afterward BW, being positively correlated with FM, TBW, BMR, metabolic age of the mothers, and negatively with the mother's smoking status. Variant genotype (GG+GC) of the IL-6 -572C>G gene polymorphism is a protector factor against obesity in mothers. All the variables considered explained 14.50% of the outcome variance.

    Since 1986, the reference of birth weight for gestational age has not been updated. The aim of this study was to set up Chinese neonatal network to investigate the current situation of birth weight in China, especially preterm birth weight, to develop the new reference for birth weight for gestational age and birth weight curve. A nationwide neonatology network was established in China. This survey was carried out in 63 hospitals of 23 provinces, municipalities and autonomous regions. We continuously collected the information of live births in participating hospitals during the study period of 2011-2014. Data describing birth weight and gestational age were collected prospectively. Newborn's birth weight was measured by electronic scale within 2 hours after birth when baby was undressed. The evaluation of gestational age was based on the combination of mother's last menstrual period, ultrasound in first trimester and gestational age estimation by gestational age scoring system. the growth curve was drawn by using LMSP method, which was conducted in GAMLSS 1.9-4 software package in R software 2.11.1. A total of 159 334 newborn infants were enrolled in this study. There were 84 447 male and 74 907 female. The mean birth weight was (3 232 ± 555) g, the mean birth weight of male newborn was (3 271 ± 576) g, the mean weight of female newborn was (3 188 ± 528) g. The test of the variables' distribution suggested that the distribution of gestational age and birth weight did not fit the normal distribution, the optimal distribution for them was BCT distribution. The Q-Q plot test and worm plot test suggested that this curve fitted the distribution optimally. The male and female neonatal birth weight curve was developed using the same method. Using GAMLSS method to establish nationwide neonatal birth weight curve, and the first time to update the birth weight reference in recent 28 years.

    It is accepted that newborns lose weight in the first few days of life. Baby-Friendly practices that support breastfeeding may affect newborn weight loss. The objective of this study were: 1) To determine whether Baby-Friendly practices are associated with term newborn weight loss day 0-2 in three feeding categories (exclusively breastfed, mixed formula fed and breastfed, and formula fed). 2) To determine whether Baby-Friendly practices increase exclusive breast feeding rates in different ethnic populations. This was a retrospective case-control study. Term newborn birth weight, neonatal weights days 0-2, feeding type, type of birth, and demographic information were collected for 1,000 births for the year before Baby-Friendly designation (2010) and 1,000 in 2013 (after designation). Ultimately 683 in the first group and 518 in the second met the inclusion criteria. Mean weight loss decreased day 0-2 for infants in all feeding types after the initiation of Baby-Friendly practices. There was a statistically significant effect of Baby-Friendly designation on weight loss for day 0-2 in exclusively breastfed infants (p Baby-Friendly practices were put in place. There was a decrease in mean weight loss day 0-2 regardless of feeding type after Baby-Friendly designation. Exclusive breast feeding increased in the presence of Baby-Friendly practices.

    Pregnancy outcomes in the United States and other developed countries are considerably better than those in many developing countries. However, adverse pregnancy outcomes are generally more common in the United States than in other developed countries. Low-birth-weight infants, born after a preterm birth or secondary to intrauterine growth restriction, account for much of the increased morbidity, mortality, and cost. Wide disparities exist in both preterm birth and growth restriction among different population groups. Poor and black women, for example, have twice the preterm birth rate and higher rates of growth restriction than do most other women. Low birth weight in general is thought to place the infant at greater risk of later adult chronic medical conditions, such as diabetes, hypertension, and heart disease. Of interest, maternal thinness is a strong predictor of both preterm birth and fetal growth restriction. However, in the United States, several nutritional interventions, including high-protein diets, caloric supplementation, calcium and iron supplementation, and various other vitamin and mineral supplementations, have not generally reduced preterm birth or growth restriction. Bacterial intrauterine infections play an important role in the etiology of the earliest preterm births, but, at least to date, antibiotic treatment either before labor for risk factors such as bacterial vaginosis or during preterm labor have not consistently reduced the preterm birth rate. Most interventions have failed to reduce preterm birth or growth restriction. The substantial improvement in newborn survival in the United States over the past several decades is mostly due to better access to improved neonatal care for low-birth-weight infants.

    Full Text Available Therapeutic strategies for patent ductus arteriosus (PDA in very preterm infants remain controversial. To identify infants likely to benefit from treatment, we analysed the efficacy of a first course of ibuprofen in small-for-gestational age (SGA newborns.This single-centre retrospective study included 185 infants born at 24+0-27+6 weeks of gestation with haemodynamically significant PDA, who were treated by intravenous ibuprofen (Pedea: 10 mg/kg on day one and 5 mg/kg on days two and three. Birth weight and gestational age (GA were analysed with reference to the standard deviations from the Olsen growth curve to define GA-specific Z-scores for birth weights. The efficacy of treatment was evaluated by echocardiography 48 hours after the last dose of ibuprofen. The primary outcome was failure of the first course of ibuprofen associated in a composite criterion with the most severe outcomes.The risk of treatment failure increased according to a continuous gradient in SGA neonates. A higher risk was observed on multiple regression analysis (crude OR: 3.8; 95% CI [1.2-12.3] p = 0.02; adjusted OR: 12.8; 95% CI [2.3-70.5] p=0.003.There is a linear relationship between infant birth weight and PDA treatment: the failure rate of a first course of ibuprofen increases with increasing degree of growth restriction.

    In adolescents, there is limited evidence on the independent and additive effect of prepregnancy body mass index (BMI) and gestational weight gain on infant birth weight. Data also show that this effect may vary by race. We sought to examine the impact of maternal prepregnancy BMI and gestational weight gain on birth weight and risk of large for gestational age (LGA) in term newborns of minority adolescent mothers. This was a retrospective cohort study of 411 singleton live term infants born to mothers ≤ 18 years. Data were abstracted from electronic medical records. Gestational weight gain was related to infant birth weight (ρ = 0.36, P gain, gestational age and Hispanic ethnicity were independent predictors of birth weight, controlling for maternal age, BMI, parity, tobacco/drug use and preeclampsia. The probability of having an LGA infant increased with weight gain [adjusted odds ratio (aOR) 1.14, 95% confidence interval (CI) 1.07-1.21] but not with BMI. Mothers who gained weight in excess of 2009 Institute of Medicine (IOM) recommendations had a greater risk of having an LGA infant compared to those who gained within recommendations (aOR 5.7, 95% CI 1.6-19.5). Minority adolescents with greater gestational weight gain had infants with higher birth weight and greater risk of LGA; BMI was not associated with either outcome. Further studies are needed to examine the applicability of the 2009 BMI-specific IOM gestational weight gain recommendations to adolescents in minority populations.

    Full Text Available The newborn's weight at birth is an important measure for newborn's health in all communities. Among developed countries, 70 percent of low birth weight (LBW newborns are preterm. The corresponding figure for undeveloped countries is only 30 percent, there are also evidence of intra-uterine growth retardation among these countries. Among effective factors on LBW, maternal related factors have important role in promotion and improvement of infants and mother's health. This study is a descriptive-analytic one and was conducted cross-sectionally through a questionnair. The study population determined by simple random sampling from newborns under coverage of urban health centers in Kohgiloye and Boyerahmad province. Necessary data collected from existing medical and health records filed in the health centers. Among 285 newborns, 88.4 percent considered with normal weight, 4 percent with IBW and 11.6 percent with more than normal weight. 7.4 percent of cases were immature. 85.3 percent of the mothers in study population were in immune range of age for pregnancy and 7.6 percent of them were illiterate. Except the sex of newborn (P=0.0008 and gestational age at birth (P<0.001 none of the variables demonstrated a significant statistical relation with the birth weight. The results of this study confirm other research's findings and reveal that with improving material factors such as mother's age, employment and literacy, the factors which are effective on birth weight, will be dependent on physiological factors such as sex of newborn and gestational age at birth.

    Background Refractive status at birth is related to gestational age. Preterm babies have myopia which decreases as gestational age increases and term babies are known to be hypermetropic. This study looked at the correlation of refractive status with birth weight in term and preterm babies, and with physical indicators of intra-uterine growth such as the head circumference and length of the baby at birth. Methods All babies delivered at St. Stephens Hospital and admitted in the nursery were eligible for the study. Refraction was performed within the first week of life. 0.8% tropicamide with 0.5% phenylephrine was used to achieve cycloplegia and paralysis of accommodation. 599 newborn babies participated in the study. Data pertaining to the right eye is utilized for all the analyses except that for anisometropia where the two eyes were compared. Growth parameters were measured soon after birth. Simple linear regression analysis was performed to see the association of refractive status, (mean spherical equivalent (MSE), astigmatism and anisometropia) with each of the study variables, namely gestation, length, weight and head circumference. Subsequently, multiple linear regression was carried out to identify the independent predictors for each of the outcome parameters. Results Simple linear regression showed a significant relation between all 4 study variables and refractive error but in multiple regression only gestational age and weight were related to refractive error. The partial correlation of weight with MSE adjusted for gestation was 0.28 and that of gestation with MSE adjusted for weight was 0.10.

    Full Text Available Refractive status at birth is related to gestational age. Preterm babies have myopia which decreases as gestational age increases and term babies are known to be hypermetropic. This study looked at the correlation of refractive status with birth weight in term and preterm babies, and with physical indicators of intra-uterine growth such as the head circumference and length of the baby at birth.All babies delivered at St. Stephens Hospital and admitted in the nursery were eligible for the study. Refraction was performed within the first week of life. 0.8% tropicamide with 0.5% phenylephrine was used to achieve cycloplegia and paralysis of accommodation. 599 newborn babies participated in the study. Data pertaining to the right eye is utilized for all the analyses except that for anisometropia where the two eyes were compared. Growth parameters were measured soon after birth. Simple linear regression analysis was performed to see the association of refractive status, (mean spherical equivalent (MSE, astigmatism and anisometropia with each of the study variables, namely gestation, length, weight and head circumference. Subsequently, multiple linear regression was carried out to identify the independent predictors for each of the outcome parameters.Simple linear regression showed a significant relation between all 4 study variables and refractive error but in multiple regression only gestational age and weight were related to refractive error. The partial correlation of weight with MSE adjusted for gestation was 0.28 and that of gestation with MSE adjusted for weight was 0.10. Birth weight had a higher correlation to MSE than gestational age.This is the first study to look at refractive error against all these growth parameters, in preterm and term babies at birth. It would appear from this study that birth weight rather than gestation should be used as criteria for screening for refractive error, especially in developing countries where the

    Several factors can affect lamb body weight (BW) and immune status during the first days of life, including colostrum source and timing of the first colostrum feeding. The aim of this study was to evaluate the effects of colostrum source (goat or sheep) and timing of the first colostrum feeding (2 or 14h after birth) on lamb BW and immune status. In this study, 40 lambs were removed from their dams at birth and randomly assigned into 4 groups of 10 lambs each. Lambs were subsequently fed at 2 or 14h after birth with goat or sheep colostrum. Blood samples and BW recording were performed before feeding. Blood plasma was used to measure the immunoglobulin concentration (IgG and IgM), chitotriosidase activity, and complement system activity (total and alternative pathways). In general, no differences in any of the measured variables were observed among the 4 groups, indicating that neither colostrum source nor timing of the first colostrum feeding had an effect on these variables. These findings may improve management on lamb farms that raise animals under artificial conditions, because our results indicate that it is not necessary to feed colostrum to lambs immediately after birth and that goat colostrum may be used to feed newborn lambs.

    This cross-sectional study was carried out to capture possible maternal factors affecting newborns' anthropometric measurements. Data were collected from eight public health centres and referral university hospital records in Tabriz and Heriss districts, north-west Iran, for 807 mother-neonate pairs delivering live singleton births and their offspring during the two years up to August 2014. The incidence of low birth weight (LBW) was 5.1%. A close correlation was found between maternal anthropometry and birth order with neonatal anthropometric data. Birth order and maternal height and body mass index (BMI) positively affected neonates' birth size (weight, length and head circumference). The rate of LBW was significantly higher for older (≥35 years), taller (≥170 cm), underweight (BMIbirth neonates. The results indicate that maternal anthropometric indices, age, iron intake and birth order influence the risk of LBW in newborns.

    To determine whether the type of medium used to culture human embryos in vitro influences neonatal birth weight after IVF/intracytoplasmic sperm injection (ICSI). A prospective study and a retrospective study. Private assisted reproduction center. The prospective study included 449 IVF/ICSI cycles from August to December 2008. The retrospective analysis was performed for 2,518 IVF/ICSI cycles from October 2006 to December 2010. In the prospective study, patients were randomized for embryo culture in Cook or Vitrolife medium. The retrospective study was performed with three different culture media (MediCult, Cook, and Vitrolife). Mean birth weight, adjusted for gestational age and gender (z score) of newborns. In the prospective study, the average z score was -0.19 ± 0.85 in Cook and 0.08 ± 1.40 in Vitrolife. In the retrospective study, the z scores obtained in each group were as follows: Cook, -0.14 ± 0.96; MediCult, 0.06 ± 1.13; and Vitrolife, 0.03 ± 1.05. No significant differences were observed regarding the birth weight of children born in the different groups in both studies. The results do not show any relationship between the medium used for in vitro culture and mean birth weight adjusted for gestational age and gender of singletons born after IVF/ICSI.

    Background Prolonged empiric antibiotics therapy in neonates results in several adverse consequences including widespread antibiotic resistance, late onset sepsis (LOS), necrotizing enterocolitis (NEC), prolonged hospital course (HC) and increase in mortality rates. Objectives To assess the risk factors and the outcome of prolonged empiric antibiotic therapy in very low birth weight (VLBW) newborns. Materials and Methods Prospective study in VLBW neonates admitted to NICU and survived > 2 W, from July 2011 - June 2012. All relevant perinatal and postnatal data including duration of antibiotics therapy (Group I 2W) and outcome up to the time of discharge or death were documented and compared. Results Out of 145 newborns included in the study, 62 were in group I, and 83 in Group II. Average duration of antibiotic therapy was 14 days (range 3 - 62 days); duration in Group I and Group II was 10 ± 2.3 vs 25.5 ± 10.5 days. Hospital stay was 22.3 ± 11.5 vs 44.3 ± 14.7 days, respectively. Multiple regression analysis revealed following risk factors as significant for prolonged empiric antibiotic therapy: VLBW especially stage II, 12 (8.3%) newborns died. Infant mortality alone and with LOS/NEC was higher in group II as compared to group I (P < 0.002 and < 0.001 respectively). Conclusions Prolonged empiric antibiotic therapy caused increasing rates of LOS, NEC, HC and infant mortality. PMID:27307961

    Excessive gestational weight gain (GWG) is associated with increased birth weight and neonatal adiposity. However, timing of excessive GWG may have a differential impact on birth outcomes. The objective of this study was to compare the effect of early and mid/late excessive GWG on newborn anthropometry in the context of the Canadian clinical recommendations that are specific for first trimester and for second/third trimesters based on maternal pre-pregnancy BMI. We included 607 glucose-tolerant women in our main analyses, after excluding women who had less than the recommended total GWG. Maternal body weight was measured in early pregnancy, mid-pregnancy, and late pregnancy. Maternal and fetal clinical outcomes were collected, including newborn anthropometry. Women were divided into four groups according to the Canadian guidelines for GWG in the first and in the second/third trimesters: (1) "overall non-excessive" (reference group); (2) "early excessive GWG"; (3) "mid/late excessive GWG"; and (4) "overall excessive GWG." Differences in newborn anthropometry were tested across GWG categories. Women had a mean (±SD) pre-pregnancy BMI of 24.7 ± 5.2 kg/m(2) and total GWG of 15.3 ± 4.4 kg. Women with mid/late excessive GWG gave birth to heavier babies (gestational age-adjusted birth weight z-score 0.33 ± 0.91) compared with women in the reference group (0.00 ± 0.77, P = 0.007), whereas women with early excessive GWG gave birth to babies of similar weight (gestational age-adjusted z-score 0.01 ± 0.86) to the reference group (0.00 ± 0.77, P = 0.84). When we stratified our analyses and investigated women who gained within the recommendations for total GWG, mid/late excessive GWG specifically was associated with greater newborn size, similar to our main analyses. Excessive GWG in mid/late pregnancy in women who did not gain weight excessively in early pregnancy is associated with increased birth size, even in those who gained within the Canadian recommendations

    Birth weight manipulation has been documented in per-case hospital reimbursement systems, in which hospitals receive more money for otherwise equal newborns with birth weight just below compared to just above specific birth weight thresholds. As hospitals receive more money for cases with weight below the thresholds, having a (reported) weight below a threshold could benefit the newborn. Also, these reimbursement thresholds overlap with diagnostic thresholds that have been shown to affect the quantity and quality of care that newborns receive. Based on the universe of hospital births in Germany from the years 2005-2011, we investigate whether weight below reimbursement relevant thresholds triggers different quantity and quality of care. We find that this is not the case, suggesting that hospitals' financial incentives with respect to birth weight do not directly impact the care that newborns receive. Copyright © 2018 Elsevier B.V.

    Background In Indonesia, the infant mortality rate in 2001 was 50 per 1000 live births, with 34.7% due to perinatal death. This perinatal death was associated with low birth weight (LBW) newborn, which was caused by prematurity, infection, birth asphyxia, hypothermia, and inadequate breast feeding. In developing countries, lack of facilities of LBW infant care leads to the utilization of kangaroo method as care to prevent hypothermia in LBW newborn. Objective To evaluate the differences of...

    We proposed weight monitoring system using load cell sensor for newborn incubator application. The weight sensing system consists of a load cell, conditioning signal circuit, and microcontroller Arduino Uno R3. The performance of the sensor was investigated by using the various weight from 0 up to 3000 g. Experiment results showed that this system has a small error of 4.313% and 12.5 g of threshold and resolution value. Compared to the typical baby scale available in local market, the proposed system has a lower error value and hysteresis.

    The manifest importance of reducing the incidence of low birth weight is most obvious for the first year of life: low birth weight is the single most important factor affecting infant morbidity and mortality. However, there is growing evidence that the adverse consequences of low birth weight continue throughout the life cycle. This review deals primarily with social causes of low birth weight.

    In the past two decades, infant mortality rates in the United States declined in African-American and White populations. Despite this, racial disparities in infant mortality rates have increased and rates of low birth weight deliveries have shown little change. In this study, we examine temporal changes in birth weight distributions, birth weight specific neonatal mortality, and the birth weight threshold for an adverse risk of survival within both racial groups in order to explore the mechanisms for the disparities in infant mortality rates. Single live births born to South Carolina resident mothers between 1975 and 1994 and considered White or African-American based on the mother's report of maternal race on the birth certificate were selected for investigation. We define the birth weight threshold for adverse survival odds as the birth weight at which 50% or more of infants in the population died within the first month of life. Despite significant increases in very low birth weight percentages, neonatal mortality rates markedly declined. Birth weight specific neonatal mortality decreased for both races, although greater reductions accrued to White low birth weight infants. By the end of the study period, the birth weight at which over 50% of newborns died within the first month of life was 696 g for Whites and 673 g for African-Americans. The ongoing decline in neonatal mortality is mainly due to reductions in birth weight specific neonatal mortality, probably related to high-risk obstetric and neonatal care. Technological developments in these areas may have differentially benefited Whites, resulting in an increasing racial disparity in mortality rates. Moreover, the relatively greater and increasing mortality risk from postmaturity and macrosomia in infants of African-America mothers may further exacerbate the racial gap in infant mortality.

    Background: To our knowledge, most research demonstrating a link between maternal nutrition and both fetal growth and offspring development after birth has been performed with nonruminants. Whether such relationships exist in large ruminants is largely unknown. Objective: We aimed to investigate whether increasing the methionine supply during late pregnancy would alter uteroplacental tissue nutrient transporters and mammalian target of rapamycin (mTOR) and their relation with newborn body weight. Methods: Multiparous Holstein cows were used in a randomized complete block design experiment. During the last 28 d of pregnancy, cows were fed a control diet or the control diet plus ethylcellulose rumen-protected methionine (0.9 g/kg dry matter intake) (Mepron; Evonik Nutrition & Care GmbH) to achieve a 2.8:1 ratio of lysine to methionine in the metabolizable protein reaching the small intestine. We collected placentome samples at parturition and used them to assess mRNA and protein expression and the phosphorylation status of mTOR pathway proteins. Results: Newborn body weight was greater in the methionine group than in the control group (44.1 kg and 41.8 kg, respectively; P ≤ 0.05). Increasing the methionine supply also resulted in greater feed intake (15.8 kg/d and 14.6 kg/d), plasma methionine (11.9 μM and 15.3 μM), and plasma insulin (1.16 μg/L and 0.81 μg/L) in cows during late pregnancy. As a result, mRNA expression of genes involved in neutral amino acid transport [solute carrier (SLC) family members SLC3A2 , SLC7A5 , SLC38A1 , and SLC38A10 ], glucose transport [ SLC2A1 , SLC2A3 , and SLC2A4 ], and the mTOR pathway [mechanistic target of rapamycin and ribosomal protein S6 kinase B1] were upregulated ( P ≤ 0.07) in methionine-supplemented cows. Among 6 proteins in the mTOR pathway, increasing the methionine supply led to greater ( P ≤ 0.09) protein expression of α serine-threonine kinase (AKT), phosphorylated (p)-AKT, p-eukaryotic elongation factor 2

    To examine the change in breastfeeding behaviors over time, among low birth weight (LBW), very low birth weight (VLBW), and normal birth weight (NBW) infants using nationally representative US data. Univariate statistics and bivariate logistic models were examined using the Early Child Longitudinal Study-Birth Cohort (2001) and National Study of Children's Health (2007 and 2011/2012). Breastfeeding behaviors improved for infants of all birth weights from 2007 to 2011/2012. In 2011/2012, a higher percentage of VLBW infants were ever breastfed compared with LBW and NBW infants. In 2011/2012, LBW infants had a 28% lower odds (95% CI, 0.57-0.92) of ever breastfeeding and a 52% lower odds (95% CI, 0.38-0.61) of breastfeeding for ≥6 months compared with NBW infants. Among black infants, a larger percentage of VLBW infants were breastfed for ≥6 months (26.2%) compared with LBW infants (14.9%). Breastfeeding rates for VLBW and NBW infants have improved over time. Both VLBW and NBW infants are close to meeting the Healthy People 2020 ever breastfeeding goal of 81.9%. LBW infants are farther from this goal than VLBW infants. The results suggest a need for policies that encourage breastfeeding specifically among LBW infants. Copyright © 2018 Elsevier Inc. All rights reserved.

    Newborns of certain immigrant mothers are smaller at birth than those of domestically born mothers. Contemporary, population-derived percentile curves for these newborns are lacking, as are estimates of their risk of being misclassified as too small or too large using conventional rather than tailored birth weight curves. We completed a population-based study of 766 688 singleton live births in Ontario from 2002 to 2007. Smoothed birth weight percentile curves were generated for males and females, categorized by maternal world region of birth: Canada (63.5%), Europe/Western nations (7.6%), Africa/Caribbean (4.9%), Middle East/North Africa (3.4%), Latin America (3.4%), East Asia/Pacific (8.1%), and South Asia (9.2%). We determined the likelihood of misclassifying an infant as small for gestational age (≤ 10th percentile for weight) or as large for gestational age (≥ 90th percentile for weight) on a Canadian-born maternal curve versus one specific to maternal world region of origin. Significantly lower birth weights were seen at gestation-specific 10th, 50th, and 90th percentiles among term infants born to mothers from each world region, with the exception of Europe/Western nations, compared with those for infants of Canadian-born mothers. For example, for South Asian babies born at 40 weeks' gestation, the absolute difference at the 10th percentile was 198 g (95% CI 183 to 212) for males and 170 g (95% CI 161 to 179) for females. Controlling for maternal age and parity, South Asian males had an odds ratio of 2.60 (95% CI 2.53 to 2.68) of being misclassified as small for gestational age, equivalent to approximately 116 in 1000 newborns; for South Asian females the OR was 2.41 (95% CI 2.34 to 2.48), equivalent to approximately 106 per 1000 newborns. Large for gestational age would be missed in approximately 61 per 1000 male and 57 per 1000 female South Asian newborns if conventional rather than ethnicity-specific birth weight curves were used.

    Full Text Available Background: Low Birth Weight (LBW babies run a higher risk of morbidity and mortality in the perinatal period. However, in our country where almost 70-80% births take place at home and peripheral hospitals, taking accurate weight is a problem due to unavailability of weighing scale and trained personnel. Hence there is a constant search for newer methods to detect LBW babies so that early interventions can be instituted. Various authors have used different surrogate anthropometric measurements from different parts of our country. In the present study, an attempt was made to validate the feasibility of using calf circumference as a predictor of LBW babies that can be used by a trained or untrained person. Objectives: To study various anthropometric measurements including calf circumference in newborns and to correlate various measurements with birth weight. Methods: The present study was conducted in the department of Social & Preventive Medicine, MLB Medical College, Jhansi (UP for a period of one year. The study included 1100 consecutively delivered neonates in the maternity ward of MLB Medical College Hospital, Jhansi (UP. The birth weight (Wt, crown heel length (CHL, crown rump length (CRL, head circumference (HC, chest circumference (CC, mid arm circumference (MAC, thigh circumference (TC and calf circumference (CC by standard techniques. All the measurements were taken by a single person throughout the study period with in 24 hours of delivery. Standard statistical methods were adopted for determination of critical limit, sensitivity, specificity and correlation coefficient of different anthropometric measurements in relation to birth weight. Results: Analysis of data indicates that out of 1100 newborns, 55.64% were low birth weight. The percentage of newborns > 2500gm was 44.36. Overall average birth weight was 2348 ± 505gm. Out of 1100 newborns, 608 (55.27% were males and 492 (44.73% were females. Average birth weight for males was 2412

    We sought to systematically review the medical literature on the maternal and newborn safety of planned home vs planned hospital birth. We included English-language peer-reviewed publications from developed Western nations reporting maternal and newborn outcomes by planned delivery location. Outcomes' summary odds ratios with 95% confidence intervals were calculated. Planned home births were associated with fewer maternal interventions including epidural analgesia, electronic fetal heart rate monitoring, episiotomy, and operative delivery. These women were less likely to experience lacerations, hemorrhage, and infections. Neonatal outcomes of planned home births revealed less frequent prematurity, low birthweight, and assisted newborn ventilation. Although planned home and hospital births exhibited similar perinatal mortality rates, planned home births were associated with significantly elevated neonatal mortality rates. Less medical intervention during planned home birth is associated with a tripling of the neonatal mortality rate. Copyright 2010 Mosby, Inc. All rights reserved.

    Full Text Available Introduction: Gestational weight gain is an important modifiable factor known to influence fetal outcomes including birth weight and adiposity. Leptin is normally correlated with adiposity and is also known to increase throughout pregnancy, as the placenta becomes a source of leptin synthesis. Several studies have reported positive correlations between cord blood leptin level and either birthweight or size for gestational age, as well as body mass index (BMI. Objective: To determine the correlation of prenatal leptin concentration in pregnant adolescents with their gestational weight gain, postpartum weight retention, and weight/length of their newborn. Methods: A cohort study was conducted on pregnant Mexican adolescents from Gestational Week 26–28 to three months postpartum (n = 168 mother–child dyads. An anthropometric assessment was made of each pregnant adolescent, and the serum level of leptin and the intake of energy were determined. The newborn was evaluated each month during postpartum. Clinical records were reviewed to obtain sociodemographic data. Bivariate correlations, tests for repeating measurements and logistic regression models were performed. Results: Leptin concentration gradually increased during the third trimester of pregnancy. At Gestation Week 36, leptin level correlated with gestational weight gain. When comparing adolescents that had the lowest and highest concentration of leptin, the former presented a mean of 6 kg less in gestational weight gain (inter-subject leptin concentration, p = 0.001; inter-subject energy intake, p = 0.497. Leptin concentration and gestational weight gain exerted an effect on the weight of the newborn (inter-subject leptin concentration for Week 32, p = 0.024; inter-subject gestational weight gain, p = 0.011.

    Full Text Available Background. Birth head trauma causing intracranial injury is one of the most common causes of neonatal mortality and morbidity. In case of suspected cranial fractures and intracranial hematomas, diagnostic methods involving radiation, such as x-ray radiography and computed tomography, are recommended. Recently, an increasing number of studies have highlighted the risk of cancer complications associated with computed tomography in infants. Therefore, diagnostic methods that reduce radiation exposure in neonates are important. One such method is ultrasonography (US. Aim. We evaluated US as a non-ionizing radiation method for diagnosis of cranial bone fractures and epidural hematomas in newborns with cephalohematomas or other birth head traumas. Material and methods. The study group included 449 newborns with the most common variant of birth head trauma: cephalohematomas. All newborns underwent transcranial-transfontanelle US for detection of intracranial changes and cranial US for visualization of bone structure in the cephalohematoma region. Children with ultrasonic signs of cranial fractures and epidural hematomas were further examined at a children’s hospital by x-ray radiography and/or computed tomography. Results and discussion. We found that cranial US for diagnosis of cranial fractures and transcranial-transfontanelle US for diagnosis of epidural hematomas in newborns were highly effective. In newborns with parietal cephalohematomas (444 children, 17 (3.8% had US signs of linear fracture of the parietal bone, and 5 (1.1% had signs of ipsilateral epidural hematoma. Epidural hematomas were visualized only when US was performed through the temporal bone and not by using the transfontanelle approach. Sixteen cases of linear fractures and all epidural hematomas were confirmed by computed tomography. Conclusion. The use of US diagnostic methods reduced radiation exposure in newborns with birth head trauma. US methods (transcranial

    Full Text Available ABSTRACT OBJECTIVE To analyze the effects of maternal pre-pregnancy body mass index and weight gain during pregnancy on the baby's birth weight. METHODS We conducted a cross-sectional study with 5,024 mothers and their newborns using a Brazilian birth cohort study. In the proposed model, estimated by structural equation modeling, we tested socioeconomic status, age, marital status, pre-pregnancy body mass index, smoking habit and alcohol consumption during pregnancy, hypertension and gestational diabetes, gestational weight gain, and type of delivery as determinants of the baby's birth weight. RESULTS For a gain of 4 kg/m2 (1 Standard Deviation [SD] in pre-pregnancy body mass index, there was a 0.126 SD increase in birth weight, corresponding to 68 grams (p < 0.001. A 6 kg increase (1 SD in gestational weight gain represented a 0.280 SD increase in newborn weight, correponding to 151.2 grams (p < 0.001. The positive effect of pre-pregnancy body mass index on birth weight was direct (standardized coefficient [SC] = 0.202; p < 0.001, but the negative indirect effect was small (SC = -0.076, p < 0.001 and partially mediated by the lower weight gain during pregnancy (SC = -0.070, p < 0.001. The positive effect of weight gain during pregnany on birth weight was predominantly direct (SC = 0.269, p < 0.001, with a small indirect effect of cesarean delivery (SC = 0.011; p < 0.001. Women with a higher pre-pregnancy body mass index gained less weight during pregnancy (p < 0.001. CONCLUSIONS The effect of gestational weight gain on the increase in birth weight was greater than that of pre-pregnancy body mass index.

    Birth weight is considered as the most important indicator of growth and intrauterine development as well as the nutritional status of the newborn. Several reports have demonstrated the influence of both biological and social variables on low birth weight, among which being discussed is the influence of the mothers work activities. Two hundred and thirty-two newborns were studied at the Regional Hospital "20 de Noviembre" of the Institute de Seguridad y Servicios Sociales para los Trabajadores del Estado (ISSSTE) and selected based on inclusion and exclusion criteria which homogenized the sample and allowed to associate the work status of the mother with the low birth weight of the child. The somatometric data of the newborns was obtained from official registrars from the Perinatology Ward and directly from the mothers who were interviewed. The results did not significant statistical differences in the weight of the newborns of those mothers who do work than in those who don't. It was concluded that for this sample, the favorable socioeconomic fund established by a double family income apparently compensates any disadvantages which the work activity could have on the newborns' weight.

    2006-01-01

    The aim of this study was to estimate the birth weight distribution and prevalence of low birth weights (LBW) in Irbid, Jordan, and to determine some of the contributing risk factors. A cross-sectional design was used to study women who delivered in Prince Rashed Hospital (PRH). Respondents were 2256 mothers ranging in age from 15-45 years. Anthropometric measurements and interviews were used to determine the risk factors. The birth weights and anthropometric measurements of all babies born alive in PRH during the period were collected. Post-delivery weight and other measurements of respondents were also collected. The mean birth weight of the newborns in the study was 2812 g. Twenty-two percent of the newborns weighed between 700 and 2499 g. About 39% of respondents had urinary tract infection while 29% suffered from anemia, and 10% had bleeding during pregnancy. All anthropometric measurements were significantly associated with LBW. Mothers who were younger in age at their first delivery, had low post-delivery weight, and bled during pregnancy, were more likely to have LBW babies. There is also a need to discourage early pregnancies and to encourage utilization of mother and child health services, and treat concomitant illnesses during pregnancy. (author)

    Ana Karine da Costa Monteiro Souza

    Full Text Available ABSTRACT Purpose: to compare the weight gain among newborns submitted to the kangaroo method and those not submitted to it, and to analyze the factors that may influence this gain: length of hospital stay, gestational age, corrected gestational age, birth weight, weight on the first day of follow-up, duration of gastric tube feeding, duration of oral feeding, and type of diet. Methods: a cross-sectional, quantitative study, with 86 newborns divided into two groups: group 1, with 48 neonates undergoing skin-to-skin contact and Group 2, 38 newborns who did not have this contact. Weights were recorded until hospital discharge. Results: a greater weight gain in Group 1, a longer time of hospitalization in Group 2, and a significant difference in weight gain related to the type of diet in Group 2. Conclusion: skin-to-skin contact has a positive influence on weight gain and length of hospital stay of newborns. The use of an infant formula does not influence weight gain for dyads who experienced skin-to-skin contact. Gestational age, corrected gestational age, birth weight, weight on the first day of follow-up, duration of gastric tube feeding, duration of oral feeding are not correlated with weight gain.

    Full Text Available A longitudinal and prospective study was carried out at two state-operated maternity hospitals in Belo Horizonte during 1996 in order to assess the weight of preterm appropriate-for-gestational-age newborns during the first twelve weeks of life. Two hundred and sixty appropriate-for-gestational-age preterm infants with birth weight <2500 g were evaluated weekly. The infants were divided into groups based on birth weight at 250-g intervals. Using weight means, somatic growth curves were constructed and adjusted to Count's model. Absolute (g/day and relative (g kg-1 day-1 velocity curves were obtained from a derivative of this model. The growth curve was characterized by weight loss during the 1st week (4-6 days ranging from 5.9 to 13.3% (the greater the percentage, the lower the birth weight, recovery of birth weight within 17 and 21 days, and increasingly higher rates of weight gain after the 3rd week. These rates were proportional to birth weight when expressed as g/day (the lowest and the highest birth weight neonates gained 15.9 and 30.1 g/day, respectively. However, if expressed as g kg-1 day-1, the rates were inversely proportional to birth weight (during the 3rd week, the lowest and the highest weight newborns gained 18.0 and 11.5 g kg-1 day-1, respectively. During the 12th week the rates were similar for all groups (7.5 to 10.2 g kg-1 day-1. The relative velocity accurately reflects weight gain of preterm infants who are appropriate for gestational age and, in the present study, it was inversely proportional to birth weight, with a peak during the 3rd week of life, and a homogeneous behavior during the 12th week for all weight groups.

    In 1989, the state of Tennessee adopted a new birth certificate which incorporates changes recommended by the National Center for Health Statistics in the revised US Standard Certificate of Live Birth. The data now being collected are intended to provide improved information for understanding maternal and infant health issues. To assess data quality, the authors compared information reported on the 1989 Tennessee birth certificates with the same data obtained from an ongoing case-control study in which the delivery hospital medical records of mothers and infants were reviewed by trained nurse abstractors using a structured data collection instrument. Cases (n = 1,016) were all infants born in Tennessee in 1989 with birth weights less than 1,500 g or other infants who died during the first 28 days of life. The infants were identified from linked birth-death certificate files. Control infants (n = 634) were randomly selected from the noncase population. The most reliable information obtained from birth certificates was descriptive demographic data and birth weight. The quality of information obtained from the new birth certificate checkboxes varied. Routine medical procedures were better reported on the birth certificates than relatively uncommon conditions and occurrences, even serious ones. Caution is needed in using birth certificate data for assessment of maternal medical risk factors, complications of labor and delivery, abnormal conditions of the newborn, and congenital anomalies, since sensitivity is low.

    Maternal exposure to air pollution and traffic noise has been suggested to impair fetal growth, but studies have reported inconsistent findings. Objective To investigate associations between residential air pollution and traffic noise during pregnancy and newborn's size at birth. From a national birth cohort we identified 75,166 live-born singletons born at term with information on the children's size at birth. Residential address history from conception until birth was collected and air pollution (NO2 and NOx) and road traffic noise was modeled at all addresses. Associations between exposures and indicators of newborn's size at birth: birth weight, placental weight and head and abdominal circumference were analyzed by linear and logistic regression, and adjusted for potential confounders. In mutually adjusted models we found a 10μg/m(3) higher time-weighted mean exposure to NO2 during pregnancy to be associated with a 0.35mm smaller head circumference (95% confidence interval (CI): 95% CI: -0.57; -0.12); a 0.50mm smaller abdominal circumference (95% CI: -0.80; -0.20) and a 5.02g higher placental weight (95% CI: 2.93; 7.11). No associations were found between air pollution and birth weight. Exposure to residential road traffic noise was weakly associated with reduced head circumference, whereas none of the other newborn's size indicators were associated with noise, neither before nor after adjustment for air pollution. This study indicates that air pollution may result in a small reduction in offspring's birth head and abdominal circumference, but not birth weight, whereas traffic noise seems not to affect newborn's size at birth.

    Previous studies have produced conflicting results with regard to the association between birth weight and developmental stuttering. This study sought to determine whether birth weight was associated with childhood and/or adolescent stuttering in three British birth cohort samples. Logistic regression analyses were carried out on data from the Millenium Cohort Study (MCS), British Cohort Study (BCS70) and National Child Development Study (NCDS), whose initial cohorts comprised over 56,000 individuals. The outcome variables were parent-reported stuttering in childhood or in adolescence; the predictors, based on prior research, were birth weight, sex, multiple birth status, vocabulary score and mother's level of education. Birth weight was analysed both as a categorical variable (low birth weight, stuttering during childhood (age 3, 5 and 7 and MCS, BCS70 and NCDS, respectively) or at age 16, when developmental stuttering is likely to be persistent. None of the multivariate analyses revealed an association between birth weight and parent-reported stuttering. Sex was a significant predictor of stuttering in all the analyses, with males 1.6-3.6 times more likely than females to stutter. Our results suggest that birth weight is not a clinically useful predictor of childhood or persistent stuttering. Copyright © 2013 Elsevier Inc. All rights reserved.

    Maternal metabolites and metabolic networks underlying associations between maternal glucose during pregnancy and newborn birth weight and adiposity demand fuller characterization. We performed targeted and nontargeted gas chromatography/mass spectrometry metabolomics on maternal serum collected at fasting and 1 h following glucose beverage consumption during an oral glucose tolerance test (OGTT) for 400 northern European mothers at ∼28 weeks' gestation in the Hyperglycemia and Adverse Pregnancy Outcome Study. Amino acids, fatty acids, acylcarnitines, and products of lipid metabolism decreased and triglycerides increased during the OGTT. Analyses of individual metabolites indicated limited maternal glucose associations at fasting, but broader associations, including amino acids, fatty acids, carbohydrates, and lipids, were found at 1 h. Network analyses modeling metabolite correlations provided context for individual metabolite associations and elucidated collective associations of multiple classes of metabolic fuels with newborn size and adiposity, including acylcarnitines, fatty acids, carbohydrates, and organic acids. Random forest analyses indicated an improved ability to predict newborn size outcomes by using maternal metabolomics data beyond traditional risk factors, including maternal glucose. Broad-scale association of fuel metabolites with maternal glucose is evident during pregnancy, with unique maternal metabolites potentially contributing specifically to newborn birth weight and adiposity. © 2016 by the American Diabetes Association.

Methods Baseline data of 435 adult women and their singletons born between January and February 2012 at a public hospital in Brazil were used. Logistic regression was applied to determine the independent importance of pre-pregnancy weight and GWG for large for gestational age (LGA) newborns. Results Among all mothers, 37.9 % were overweight and obese before pregnancy and 45.3 % experienced excessive GWG. Among the newborns, 24.4 % were classified as LGA. Univariate analysis showed an association of family income, GWG, pre-pregnancy BMI and excessive GWG with LGA newborns. Smoking before and during pregnancy was associated with a decreased likelihood of giving birth to an LGA newborn compared to mothers who did not smoke. After adjustment for confounding variables, age at birth of first child, GWG, HbA1c and pre-pregnancy weight-GWG were significant and independent determinants of giving birth to an LGA newborn. Mothers with pre-pregnancy overweight and excessive GWG were more likely to deliver an LGA newborn (OR 2.54, P weight and experienced adequate GWG. Conclusions for Practice Age at first birth of child, GWG, HbA1c and pre-pregnancy overweight combined with excessive GWG are independent determinants of LGA newborns. The results of this study suggest that both primary prevention of overweight in women of childbearing age and management of GWG may be important strategies to reduce the number of LGA newborns and, consequently, the long-term public health burden of obesity.

    There is an increasing body of literature focusing on differences in newborn size between different population subgroups defined by racial, ethnic, and immigration status. The interpretation of these differences as pathological or as merely reflecting normal variability is not straightforward and may have consequences for the provision of obstetric and neonatal care to minority populations. In this review, we critically assess some methodological issues affecting the assessment of newborn size and their potential implications for minority populations. In particular, we discuss the pros and cons of different types of newborn birth-weight (BW) charts (i.e., single local population-based references, minority-specific references, and a single international standard) to determine abnormal newborn size, with emphasis on immigrant populations. We conclude that size alone is not enough to inform clinical decisions and that all newborn size charts should be used as screening tools, not as diagnostic tools. Parental minority status may be regarded as a marker and used to further inquire about individual risk factors, particularly among immigrants who may not have a complete medical history in the new country. Finally, we outline areas for further research and recommendations for clinical practice. Copyright © 2015 Elsevier Ltd. All rights reserved.

    There was strong evidence from studies conducted in developed countries that second-hand smoke (SHS) exposure is detrimental to the birth weight of newborn. This study was conducted to determine the effect of exposure to SHS smoke during pregnancy on the weight of newborns. A retrospective cohort study was conducted. The exposed group consists of 209 postnatal women who experienced SHS exposure at home because of a husband or other housemate who smoked inside the house throughout the pregnancy. The non-exposed group included 211 women who did not experience SHS exposure at home or at work during pregnancy. We excluded non-Malay ethnicity, multiple births, and congenital defects. There was a significant difference in the adjusted mean birth weight between exposed infants [2893.0 g (95% confidence interval (CI): 2781.3, 3004.7)] and not exposed infants to SHS [3046.1 g (95% CI 2929.5, 3162.6) (P cigarette (P < 0.001). The incidence of low birth weight (LBW) was higher in exposed women, [10% (95% CI: 5.94, 14.06)] compared to non-exposed women [4.7% (95% CI: 1.85, 7.55)]. This study found a significant association between SHS exposure during pregnancy and decreased birth weight.

    Infants with low birth weights are provided with hospital nutrition support to enhance their survivability and body weights. However, different hospitals have different nutrition support formulas. Therefore, the effectiveness of these nutrition support formulas should be investigated. To assess the effect of hospital nutrition support on growth velocity and nutritional status of low birth weight infants at Al-Noor hospital, Saudi Arabia. A cross-sectional study was conducted between October, 2010 and December, 2012. Three hundred newborns were recruited from Al-Noor Hospital in Makkah city, Saudi Arabia. Infants were selected according to their birth weights and were divided equally into three groups; (i) Low Birth Weight (LBW) infants (1501- 2500 g birth weight), (ii) Very Low Birth Weight (VLBW) infants (1001-1500 g birth weight) and (iii) Extremely Low Birth Weight (ELBW) infants ( 0.05) were observed among groups. Serum calcium, phosphorus and potassium levels at discharge were higher (p < 0.05) than that at birth for ELBW and VLBW groups; while sodium level decreased in ELBW group to be within normal ranges. Albumin level was improved (p < 0.05) in ELBW group. Health care management for low birth weight infants in Al-Noor Hospital was not sufficient to achieve normal growth rate for low birth weight infants, while biochemical indicators were remarkably improved in all groups.

  16. How Neighborhood Disadvantage Reduces Birth Weight

    Directory of Open Access Journals (Sweden)

    Full Text Available In this analysis we connect structural neighborhood conditions to birth outcomes through their intermediate effects on mothers’ perceptions of neighborhood danger and their tendency to abuse substances during pregnancy. We hypothesize that neighborhood poverty and racial/ethnic concentration combine to produce environments that mothers perceive as unsafe, thereby increasing the likelihood of negative coping behaviors (substance abuse. We expect these behaviors, in turn, to produce lower birth weights. Using data from the Fragile Families and Child Wellbeing Study, a survey of a cohort of children born between 1998 and 2000 and their mothers in large cities in the United States, we find little evidence to suggest that neighborhood circumstances have strong, direct effects on birth weight. Living in a neighborhood with more foreigners had a positive effect on birth weight. To the extent that neighborhood conditions influence birth weight, the effect mainly occurs through an association with perceived neighborhood danger and subsequent negative coping behaviors. Poverty and racial/ethnic concentration increase a mother’s sense that her neighborhood is unsafe. The perception of an unsafe neighborhood, in turn, associates with a greater likelihood of smoking cigarettes and using illegal drugs, and these behaviors have strong and significant effects in reducing birth weight. However, demographic characteristics, rather than perceived danger or substance abuse, mediate the influence of neighborhood characteristics on birth weight.

    We sought to evaluate perinatal morbidity by delivery location (hospital, freestanding birth center, and home). Selected 2006 US birth certificate data were accessed online from the Centers for Disease Control and Prevention. Low-risk maternal and newborn outcomes were tabulated and compared by birth facility. A total of 745,690 deliveries were included, of which 733,143 (97.0%) occurred in hospital, 4661 (0.6%) at birth centers, and 7427 (0.9%) at home. Compared with hospital deliveries, home and birthing center deliveries were associated with more frequent prolonged and precipitous labors. Home births experienced more frequent 5-minute Apgar scores home and birthing center deliveries were associated with less frequent chorioamnionitis, fetal intolerance of labor, meconium staining, assisted ventilation, neonatal intensive care unit admission, and birthweight Home births are associated with a number of less frequent adverse perinatal outcomes at the expense of more frequent abnormal labors and low 5-minute Apgar scores.

    Birth weight centile curves are commonly used as a screening tool and to assess the position of a newborn on a given reference distribution. Birth weight of twins are known to be less than those of comparable singletons and twin-specific birth weight centile curves are recommended for use. In this study, we aim to construct gestational age specific birth weight centile curves for twins born in south India. The study was conducted at the Christian Medical College, Vellore, south India. The birth records of all consecutive pregnancies resulting in twin births between 1991 and 2005 were reviewed. Only live twin births between 24 and 42 weeks of gestation were included. Birth weight centiles for gestational age were obtained using the methodology of generalized additive models for location, scale and shape (GAMLSS). Centiles curves were obtained separately for monochorionic and dichorionic twins. Of 1530 twin pregnancies delivered during the study period (1991-2005), 1304 were included in the analysis. The median gestational age at birth was 36 weeks (1st quartile 34, 3rd quartile 38 weeks). Smoothed percentile curves for birth weight by gestational age increased progressively till 38 weeks and levels off thereafter. Compared with dichorionic twins, monochorionic twins had lower birth weight for gestational age from after 27 weeks. We provide centile values of birth weight at 24 to 42 completed weeks of gestation for twins born in south India. These charts could be used both in routine clinical assessments and epidemiological studies.

    To establish the level of birth weight discordance at which perinatal morbidity increases in monochorionic and dichorionic twin pregnancy. This prospective multicenter cohort study included 1,028 unselected twin pairs recruited over a 2-year period. Participants underwent two weekly ultrasonographic surveillance from 24 weeks of gestation with surveillance of monochorionic twins two-weekly from 16 weeks. Analysis using Cox proportional hazards compared a composite measure of perinatal morbidity (including any of the following: mortality, respiratory distress syndrome, hypoxic-ischemic encephalopathy, periventricular leukomalacia, necrotizing enterocolitis, or sepsis) at different degrees of birth weight discordance with adjustment for chorionicity, gestational age, twin-twin transfusion syndrome, birth order, gender, and growth restriction. Perinatal outcome data were recorded for 977 patients (100%) who continued the study with both fetuses alive beyond 24 weeks, including 14 cases of twin-twin transfusion syndrome. Adjusting for gestation at delivery, twin order, gender, and growth restriction, perinatal mortality, individual morbidity, and composite perinatal morbidity were all seen to increase with birth weight discordance exceeding 18% for dichorionic pairs (hazard ratio 2.2, 95% confidence interval [CI] 1.6-2.9, Pbirth weights were appropriate for gestational age. : The threshold for birth weight discordance established by this prospective study is 18% both for dichorionic twin pairs and for monochorionic twins without twin-twin transfusion syndrome. This threshold is considerably lower than that defined by many retrospective series as pathologic. We suggest that an anticipated difference of 18% in birth weight should prompt more intensive fetal monitoring.

    Full Text Available Background & aim: Low birth weight (LBW is the center of focus as a cause of many social, emotional, and mental deficiencies. The identification of the probable causes of LBW is considered as an important measure in reducing the prevalence of this health problem. Regarding this, the present study was carried out to compare some of the mental and social traits in the mothers of normal weight newborns and those with LBW neonates. Methods: This cross-sectional study was conducted on the parents of 400 neonates selected by the proportional sampling technique in Isfahan, Iran. The participants were assigned into two groups of mothers including 200 subjects with LBW neonate and 200 cases with normal birth weight newborns. The data were collected using the Depression, Anxiety, and Stress Scale (DASS-42 developed by Lavibond and Lavibond in 1995 and the couple satisfaction index. Results: According to the results of the study, there was a significant difference between the two groups of mothers in terms of depression, stress, anxiety, age, medicine consumption, level of education, and marital satisfaction (P

    Full Text Available OBJECTIVE: In order to determine the relationship between some maternal anthropometric indicators and birth weight, crown-heel length and newborn's head circumference, 92 pregnant women were followed through at the prenatal service of hospital in S. Paulo, Brazil. MATERIAL AND METHOD: The following variables were established for the mother: weight, height, mid-upper arm circumference, pre-pregnancy weight, gestational weight gain and Quetelet's index. For the newborn the following variables were recorded: birth weight, crown-heel length, head circumference and gestational age by Dubowitz's method. RESULTS: Significant associations were noted between gestational age and newborn variables. In addition, maternal mid-arm circumference (MUAC and pre-pregnancy weight were found to be positively correlated to birth weight (r=0.399; r=0.378, respectively. The multivariate linear regression shows that gestational age, mother's arm circumference and pre-pregnancy weight continue to be significant predictors of birth weight. On the other hand, only gestational age and mother's age was associated with crown-heel length. Similarly MUAC was significantly associated with crown-heel length (r= 0.306; P=0.0030. CONCLUSION: Maternal mid-upper arm circumference is a potential indicator of maternal nutritional status. It could be used in association with other anthropometric measurements, instead of pre-pregnancy weight, as an alternative indicator to assess women at risk of poor pregnancy outcome.

    Birth weight is a crucial determinant of the development potential of the newborn. Abnormal newborn weights are associated with negative effects on the health and survival of the baby and the mother. Therefore, this study was designed to determine the prevalence of abnormal birth weight and related factors in Northern region, Ghana. The study was a facility-based cross-sectional survey in five hospitals in Northern region, Ghana. These hospitals were selected based on the different socio-economic backgrounds of their clients. The data on birth weight and other factors were derived from hospital records. It was observed that low birth weight is still highly prevalent (29.6%), while macrosomia (10.5%) is also increasingly becoming important. There were marginal differences in low birth weight observed across public hospitals but marked difference in low birth weight was observed in Cienfuegos Suglo Specialist Hospital (Private hospital) as compared to the public hospitals. The private hospital also had the highest prevalence of macrosomia (20.1%). Parity (0-1) (p malnutrition phenomenon, which is currently being experienced by developing and transition counties. Both low birth weight and macrosomia are risk factors, which could contribute considerably to the current and future burden of diseases. This may overstretch the already fragile health system in Ghana. Therefore, it is prudent to recommend that policies aiming at reducing diet related diseases should focus on addressing malnutrition during pregnancy and early life.

    Full Text Available Recent surveillance data suggest that mean birth weight has begun to decline in several developed countries. The aim of this study is to examine the changes in birth weight among singleton live births from 2002 to 2012 in Guangzhou, one of the most rapidly developed cities in China.We used data from the Guangzhou Perinatal Health Care and Delivery Surveillance System for 34108 and 54575 singleton live births with 28-41 weeks of gestation, who were born to local mothers, in 2002 and 2012, respectively. The trends in birth weight, small (SGA and large (LGA for gestational age and gestational length were explored in the overall population and gestational age subgroups.The mean birth weight decreased from 3162 g in 2002 to 3137 g in 2012 (crude mean difference, -25 g; 95% CI, -30 to -19. The adjusted change in mean birth weight appeared to be slight (-6 g from 2002 to 2012 after controlling for maternal age, gestational age, educational level, parity, newborn's gender and delivery mode. The percentages of SGA and LGA in 2012 were 0.6% and 1.5% lower than those in 2002, respectively. The mean gestational age dropped from 39.2 weeks in 2002 to 38.9 weeks in 2012. In the stratified analysis, we observed the changes in birth weight differed among gestational age groups. The mean birth weight decreased among very preterm births (28-31 weeks, while remained relatively stable among other gestational age subcategories.Among local population in Guangzhou from 2002 to 2012, birth weight appeared to slightly decrease. The percentage of SGA and LGA also simultaneously dropped, indicating that newborns might gain a healthier weight for gestational age.

    Full Text Available An analysis of the literature was carried out whose main objective was to evaluate the influence of the Body Mass Index, pregestational and gestational, on the weight of newborns. We designed a systematic review of observational studies (retrospective, cross-sectional or prospective, fulfilling the guidelines of the review protocol Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA. The protocol was registered on the PROSPERO website, and it was assigned the registration number: CRD42017080707. We searched by applying the inclusion criteria in the following electronic databases; Pubmed, Scielo, Cuiden, Google Scholar and Scopus. We identified 372 articles that met the inclusion rules. We carried out a screening in duplicates, reading the title and abstract of the identified articles, and subsequently an in-depth reading of the articles, 10 articles were included in the present systematic review. Once the articles are analyzed, it is observed in the results that the BMI is positive and significantly related to the birth weight of the children. Thus, mothers who begins gestation with low weight have a greater risk of conceiving children with low birth weight for gestational age, just as obese and overweight women have a greater risk of having macrosomic children. No data have been observed that relate the weight of newborns of women with normal weight, with the weight gain of mothers.

    To analyze the relationship between route of delivery and other aspects of pregnancy and the occurrence of intracranial hemorrhage in newborns of very low weight at a teaching hospital in South Brazil. A case-control study was conducted. Medical records of all patients who were born weighing ≤ 1,500 g and who were submitted to transfontanellar ultrasonography were analyzed from January 2011 to September 2014. The cases were newborns with diagnosis of intracranial hemorrhage, while newborns with regular exams were used as controls. Differences between groups were analyzed by the Student t test and by χ2 or Fisher exact tests, and association was determined using the odds ratio with a 95% confidence interval and α = 5%. A total of 222 newborns with birth weight ≤ 1,500 g were recorded; of these, 113 were submitted to transfontanellar ultrasonography and were included in the study. Sixty-nine (61.1%) newborns were diagnosed with intracranial hemorrhage (cases) and 44 (38.9%) showed no abnormal results (controls). Most cases had grade I hemorrhage (96.8%) originating from the germinative matrix (95.7%). The predominant route of delivery was caesarean section (81.2% of the cases and 72.7% of the controls). Five deaths were recorded (3 cases and 2 controls). Gestational age ranged from 24 to 37 weeks. Median birth weight was 1,205 g (range: 675-1,500 g). The median time of hospitalization was 52 days, ranging from 5 to 163 days. Grade I intracranial hemorrhage from the germinative matrix was the most frequent. No differences were found between cases and controls for the variables studied.

    Full Text Available Abstract Objective: To determine the risk factors for weight loss over 8% in full-term newborns at postpartum discharge from a Baby Friendly Hospital. Methods: The cases were selected from a cohort of infants belonging to a previous study. Healthy full-term newborns with birth weight ≥2.000g, who were exclusively breastfed were included and excluded twins and those undergoing phototherapy as well as those discharged after 96h of life. The analyzed maternal and neonatal variables were maternal age, parity, ethnicity, type of delivery, maternal diabetes, gender, gestational age and appropriate weight for age. Adjusted multiple and univariate Cox regression analyses were used, considering as significant p8% were cesarean delivery and older maternal age. At the adjusted multiple regression analysis, the model to explain the weight loss was cesarean delivery (Relative risk 2.27, 95% of Confidence Interval 1.54–3.35. Conclusions: The independent predictor for weight loss>8% in exclusively breastfed full-term newborns in a Baby-Friendly Hospital was the cesarean delivery. It is possible to reduce the number of cesarean sections to minimize neonatal excessive weight loss and the resulting use of infant formula during the first week of life.

    Full Text Available Introduction: Birth weight is one of the most important determinant of the neonatal and infant survival. The goal of reducing low birth weight incidence by at least one third between 2000 and 2010 was one of the major goals in ‘A World Fit for Children’. The prevention of low birth weight is a public health priority, particularly in developing countries with high magnitude. Knowledge regarding magnitude and correlates help prevent the condition. Hence, the present study was carried out to study the magnitude and the correlates of low birth weight. Methodology: Two hundred and six newborn babies were recruited on a birth cohort from two Primary Health Centres (PHC of Wardha district to study growth in first year of life. Here, we present the baseline analysis of 172 children who were born full term to study the correlates of low birth weight babies born full term. The children were recruited within first week of their birth. Data was collected on socio-demographic profile, birth history, and maternal characteristics. Proportion of low birth weight was expressed in percentage along with 95% confidence interval. Univariate and multivariate logistic regression was used to study the correlates. Findings are expressed in odds ratios with their 95% confidence intervals. Results: The magnitude of low birth weight at term was found to be 33.1% (95% CI: 26.4%-40.4%. On univariate analysis, significant correlates of low birth weight were consumption of less than 50 iron-folic acid tables and being born to than mother. On multivariate analysis, the significant correlates were female sex of child (OR=2.856, being born to thin mother (OR=5.320, consumption of less than 50 tablets (OR=4.648, and complications of pregnancy (OR=2.917. Conclusions: The magnitude of low birth weight is very high and modifiable correlates of low birth weight are nutritional status of mother, lower consumption of IFA tablets and complications of pregnancy.

  18. Risk factors for the increasing trend in low birth weight among live births born by vaginal delivery, Brazil

    2000-01-01

    Full Text Available OBJECTIVE: To identify risk factors for low birth weight (LBW among live births by vaginal delivery and to determine if the disappearance of the association between LBW and socioeconomic factors was due to confounding by cesarean section. METHODS: Data were obtained from two population-based cohorts of singleton live births in Ribeirão Preto, Southeastern Brazil. The first one comprised 4,698 newborns from June 1978 to May 1979 and the second included 1,399 infants born from May to August 1994. The risks for LBW were tested in a logistic model, including the interaction of the year of survey and all independent variables under analysis. RESULTS: The incidence of LBW among vaginal deliveries increased from 7.8% in 1978--79 to 10% in 1994. The risk was higher for: female or preterm infants; newborns of non-cohabiting mothers; newborns whose mothers had fewer prenatal visits or few years of education; first-born infants; and those who had smoking mothers. The interaction of the year of survey with gestational age indicated that the risk of LBW among preterm infants fell from 17.75 to 8.71 in 15 years. The mean birth weight decreased more significantly among newborns from qualified families, who also had the highest increase in preterm birth and non-cohabitation. CONCLUSIONS: LBW among vaginal deliveries increased mainly due to a rise in the proportion of preterm births and non-cohabiting mothers. The association between cesarean section and LBW tended to cover up socioeconomic differences in the likelihood of LBW. When vaginal deliveries were analyzed independently, these socioeconomic differences come up again.

    Currently preterm births are the leading causes of newborn deaths and newborn mortality in developed countries. Infants born prematurely remain vulnerable to many acute complications and long-term disabilities. There is a growing concern surrounding the moral and ethical implications of the complex and technological care being provided to extremely low birth weight infants in neonatal intensive care units in the developed nations. The purpose of this study was to describe the ethical and moral issues that neonatal intensive care nurses experience when caring for low birth weight preterm infants and their families. A phenomenological method design was used to describe the lived experiences of nurses with ethical and moral issues encountered in the neonatal intensive care unit. One-on-one, semi-structured interviews using open-ended questions were used to gather data from the participants. The setting for this study was a 97-bed neonatal intensive care. A total of 16 female nurses were interviewed. Approval to conduct the research study was obtained from the institutional review board of the hospital where the study was conducted. Formal signed consent was obtained from each participant. To ensure confidentiality, each participant was asked to choose a confederate name to be used in the interview and the transcriptions. The thematic analysis identified five recurring themes: (a) at the edge of viability, (b) infant pain and discomfort, (c) crucial decisions, (d) communicating with parents, and (e) letting go. Neonatal intensive care unit nurses indicated that they often had challenges to their own sense of morality as they struggled to protect the infant from pain and unnecessary discomfort, provide care to an infant and their family whom they thought was faced with a lifetime of challenges and poor health, accepting decisions made by parents, and feeling as if parents were not adequately informed about outcomes. © The Author(s) 2014.

    Objectives Prevention of obesity should start as early as possible after birth. We aimed to build clinically useful equations estimating the risk of later obesity in newborns, as a first step towards focused early prevention against the global obesity epidemic. Methods We analyzed the lifetime Northern Finland Birth Cohort 1986 (NFBC1986) (N = 4,032) to draw predictive equations for childhood and adolescent obesity from traditional risk factors (parental BMI, birth weight, maternal gestational weight gain, behaviour and social indicators), and a genetic score built from 39 BMI/obesity-associated polymorphisms. We performed validation analyses in a retrospective cohort of 1,503 Italian children and in a prospective cohort of 1,032 U.S. children. Results In the NFBC1986, the cumulative accuracy of traditional risk factors predicting childhood obesity, adolescent obesity, and childhood obesity persistent into adolescence was good: AUROC = 0·78[0·74–0.82], 0·75[0·71–0·79] and 0·85[0·80–0·90] respectively (all pchildhood obesity remained acceptably accurate when applied to the Italian and the U.S. cohort (AUROC = 0·70[0·63–0·77] and 0·73[0·67–0·80] respectively) and the two additional equations for childhood obesity newly drawn from the Italian and the U.S. datasets showed good accuracy in respective cohorts (AUROC = 0·74[0·69–0·79] and 0·79[0·73–0·84]) (all pchildhood obesity were converted into simple Excel risk calculators for potential clinical use. Conclusion This study provides the first example of handy tools for predicting childhood obesity in newborns by means of easily recorded information, while it shows that currently known genetic variants have very little usefulness for such prediction.

    Full Text Available Our aim was to investigate whether birth weight in mothers with diabetes mellitus type 1 is higher as compared to nondiabetic controls. Methods. A retrospective study was performed using an existing database covering the region of Flanders, Belgium. Data included the presence of diabetes type 1, hypertension, parity, maternal age, the use artificial reproductive technology, fetal- neonatal death, congenital anomalies, admission to a neonatal intensive care unit, and delivery by Caesarean section or vaginally. Results. In the period studied, 354 women with diabetes type 1 gave birth and were compared with 177.471 controls. Women with type 1 diabetes more often had a maternal age of over 35 years (16.7% versus 12.0%, P=.008, OR 1.46; 95% CI 1.09–1.95. They more frequently suffered hypertension in pregnancy (19.5% versus 4.7%, P<.0001, OR 4.91; 95% CI 3.73–6.44. Perinatal death was significantly higher in the diabetes mellitus group (3.05% versus 0.73%, P<.0001, OR 4.28; 95% CI 2.22–8.01. Caesarean section was performed almost 5 times as frequently in the diabetes versus the control group (OR 4.57; 95% CI 3.70–5.65. Birth weight was significantly higher in diabetic pregnant women from 33 until 38 weeks included, but those reaching 39 weeks and later were not different with control groups. Conclusion. In Belgium, diabetic pregnancy still carries a high risk for fetal and maternal complications; in general birth weight is significantly higher but for those reaching term there is no significant difference in birth weight.

    Polycystic ovary syndrome (PCOS) tends to run in families and excess intrauterine androgen exposure has been suggested as one possible cause of PCOS. We wanted to study the relationship between maternal and offspring sex hormone levels and the possible effects of metformin treatment in PCOS pregnancies. We performed a post hoc analysis of a trial in which 40 pregnant women with PCOS were randomized in the first trimester, to use either metformin 850 mg twice daily or placebo until delivery. Maternal venous blood and umbilical arterial and venous blood samples were collected at delivery. Outcome measures were levels of androgens, estrogens and sex hormone binding globulin (SHBG). (i) In newborns, SHBG levels were higher in the metformin group. All other hormones, both in mothers and offspring, were unaffected by metformin treatment. (ii) Mothers, who gave birth to boys, had higher estrone and estradiol levels compared with those who gave birth to girls. (iii) Male newborns had higher levels of testosterone, androstanediol glucuronide and estradiol compared with females. (iv) Positive correlations were found between maternal and newborn levels of androstenedione, dihydrotestosterone and estradiol. Intrauterine metformin exposure seems to result in elevated SHBG levels in newborns. However, at birth, maternal and newborn androgen and estrogen levels are unaffected by metformin use in pregnancy. Although androgen and estrogen levels are higher in male newborns compared with females, maternal and newborn androgen and estrogen levels are highly correlated at birth.

    Full Text Available Introduction & Objective: Recent studies have presented evidence that periodontal disease in pregnant women may be a determining factor for newborn’s low birth weight. The present investigation was carried out to verify whether there is an association between maternal periodontal disease and low birth weight of newborns.Materials and Methods: This was a case-control study on 330 women, containing 110 mothers having live newborns with weight 2500 g (control group. The existence of an association between periodontal disease and newborn’s low birth weight was evaluated by means of analytic statistics that considered other risk factors for low weight. The two groups were compared with regard to urinary infection, preeclampsia, premature rupture of membrane, placenta previa, primiparous, smoking, age, height, socioeconomic status and periodontal disease.Results: There were no statistically significant differences between the case and control groups for any of the covariables (P>0.05, but there was significant differences for principal independent variable (periodontal disease P<0.05.Conclusion: Results indicated a positive association between periodontal disease and newborn’s low birth weight. Thus periodontal disease is a possible risk factor for low birth weight.

    This study explores whether pregnant nonsmokers' exposure to environmental tobacco smoke (ETS) affects the average birth weight at term. The population studied consists of pregnant nonsmokers participating in a study called Smoke-free Newborn Study. The participants (n = 1612) answered a questionnaire during 12th to 16th gestational week about their exposure to ETS at home and outside the home. Pregnant nonsmokers exposed to ETS both at home and outside the home gave birth to children with a birth weight of 78.9 g (95% CI -143.7 to -14.1) (P=0.02) lower than the weight of children born to women unexposed to ETS. There was no significant reduction in birth weight among women exposed to ETS at home only or outside the home only. A nonsignificant dose-response association was seen between increasing daily exposure to ETS and reduction in birth weight. Nonsmoking pregnant women who were exposed to ETS at home as well as outside the home gave birth to children with a 79 g reduction in birth weight compared to children of unexposed women. The fact that exposure to ETS has an effect on the birth weight is regarded as essential. The authors recommend that pregnant women should not be exposed to passive smoking, and that it should be considered whether workplace legislation should be instituted in order to protect pregnant women against the adverse effects of passive smoking.

    Studies on birth weight and congenital anomalies in sub-Saharan regions are scarce. Data on child variables (gestational age, birth weight, sex, and congenital malformations) and maternal variables (gravidity, parity, antenatal care, previous abortions, maternal illness, age, medication, and malformation history) were collected for all neonates delivered at Ayder referral and Mekelle hospitals (Northern Ehthiopia) in a prospective study between 01-12-2011 and 01-05-2012. The total number of deliveries was 1516. More female (54%) than male neonates were born. Birth weights were 700-1,000 grams between 26 and 36 weeks of pregnancy and then increased linearly to 3,500-4,000 grams at 40 weeks. Thirty-five and 54% of neonates were very-low and low birth weight, respectively, without sex difference. Very-low birth-weight prevalence was not affected by parity. Male and female neonates from parity-2 and parity-2-4 mothers, respectively, were least frequently under weight. Sixty percent of newborns to parity -3 mothers weighed less than 2,500 grams, without sex difference. The percentage male neonates dropped from ~50% in parity-1-3 mothers to ~20% in parity-6 mothers. Diagnosed congenital malformations (~2%) were 2-fold more frequent in boys than girls. The commonest malformations were in the central nervous system (CNS; ~1.5% of newborns). Parity, low birth weight, gestational age less than 35 weeks, male sex, and lack of antenatal care were the most significant risk factors for congenital anomalies. The high prevalence of neonates with low birth weight and CNS anomalies in Northern Ethiopia was very high. The findings may reflect the harsh conditions in the past 2 decades and suggest environmental and/or nutritional causes. Male sex and parity affected the outcome of pregnancy negatively.

The association between maternal schooling and survival of very low birth weight infants was evaluated by means of Cox proportional hazard models adjusted for: prenatal care, birth weight, and gestational age. RESULTS: the study included 782 very low birth weight newborns. Of these, (28.6% died before one year of age. Neonatal mortality was 19.5%, and earlyneonatal mortality was 14.9%. Mortality was highest in the lowest weight group (71.6%. Newborns whose mothers had less than four years of schooling had 2.5 times higher risk of death than those whose mothers had eight years of schooling or more, even after adjusting for intermediate factors. CONCLUSIONS: the results showed higher mortality among very low birth weight infants. Low schooling was an independent predictor of infant death in this low-income population sample.

    Exclusive breastfeeding reduces infant infectious disease. Losing > or =10% birth weight may lead to formula use. The predictive value of first-day weight loss for subsequent weight loss has not been studied. The objective of the present study was to evaluate the relationship between weight loss at or =10%. For 1,049 infants, we extracted gestational age, gender, delivery method, feeding type, and weights from medical records. Weight nadir was defined as the lowest weight recorded during birth hospitalization. We used multivariate logistic regression to assess the effect of first-day weight loss on subsequent in-hospital weight loss. Mean in-hospital weight nadir was 6.0 +/- 2.6%, and mean age at in-hospital weight nadir was 38.7 +/- 18.5 hours. While in the hospital 6.4% of infants lost > or =10% of birth weight. Infants losing > or =4.5% birth weight at or =10% (adjusted odds ratio 3.57 [1.75, 7.28]). In this cohort, 798 (76.1%) infants did not have documented weight gain while in the hospital. Early weight loss predicts higher risk of > or =10% in-hospital weight loss. Infants with high first-day weight loss could be targeted for further research into improved interventions to promote breastfeeding.

We included 40152 registered pregnant women who had delivered between October 2013 and September 2014. attendance at prenatal care was evaluated using Kessner index. χ 2 tests were used to examine the correlations between demographic characteristics and preterm birth or low birth weight. The associations between attendance at prenatal care and birth outcomes were explored using multilevel mixed-effects logistic regression models. the prevalence for preterm birth and low birth weight was 3.31% and 2.55%. The null models showed region clustering on birth outcomes. Compared with women who received adequate prenatal care, those with intermediate prenatal care (adjusted OR 1.62, 95%CI 1.37-1.92) or inadequate prenatal care (adjusted OR 2.78, 95%CI 2.24-3.44) had significantly increased risks for preterm birth, and women with intermediate prenatal care (adjusted OR 1.31, 95%CI 1.10-1.55) or inadequate prenatal care (adjusted OR 1.70, 95%CI 1.32-2.19) had significantly increased risks for low birth weight. We found very significant dose-response patterns for both preterm birth (p-trendprenatal care in China has independent effects on both preterm birth and low birth weight. Appropriate timing and number of prenatal care visits can help to reduce the occurrence of preterm birth or low birth weight. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Stunting is prevalent by the age of 6 months in the indigenous population of the Western Highlands of Guatemala. The objective of this study was to determine the time course and predictors of linear growth failure and weight-for-age in early infancy. One hundred and forty eight term newborns had measurements of length and weight in their homes, repeated at 3 and 6 months. Maternal measurements were also obtained. Mean ± SD length-for-age Z-score (LAZ) declined from newborn -1.0 ± 1.01 to -2.20 ± 1.05 and -2.26 ± 1.01 at 3 and 6 months respectively. Stunting rates for newborn, 3 and 6 months were 47%, 53% and 56% respectively. A multiple regression model (R(2) = 0.64) demonstrated that the major predictor of LAZ at 3 months was newborn LAZ with the other predictors being newborn weight-for-age Z-score (WAZ), gender and maternal education∗maternal age interaction. Because WAZ remained essentially constant and LAZ declined during the same period, weight-for-length Z-score (WLZ) increased from -0.44 to +1.28 from birth to 3 months. The more severe the linear growth failure, the greater WAZ was in proportion to the LAZ. The primary conclusion is that impaired fetal linear growth is the major predictor of early infant linear growth failure indicating that prevention needs to start with maternal interventions. © 2013.

    Little is known about the developing breastfeeding behaviour of newborn infants. This study describes infants' prebreastfeeding behaviour during the second day of life and explores possible associations with infant characteristics. We studied 13 mothers and healthy full-term infants after normal births. At 24-48 hours of life, the newborns were placed in skin-to-skin contact with their mothers for breastfeeding and were video-filmed. The order, frequency and duration of predefined infant prefeeding behaviours and suckling were coded and analysed using computer-based video software. Prefeeding behaviours occurred in the following order: rooting, hand to mouth movements, licking of the nipple and hand to breast to mouth movements. The infants started to suckle at a median of one to two minutes. Rooting was the most common behaviour, observed in 12 infants. The duration of rooting movements during the last minute before breastfeeding was inversely related to neonatal age (p ≤ 0.001) and positively related to neonatal weight loss (p = 0.02) after birth. Infants exhibited a distinct sequence of prefeeding behaviours during the second day of life, and our findings suggest that rooting movements were governed by mechanisms involved in the regulation of food intake and weight gain. ©2015 Foundation Acta Paediatrica.

    Full Text Available Prevention of obesity should start as early as possible after birth. We aimed to build clinically useful equations estimating the risk of later obesity in newborns, as a first step towards focused early prevention against the global obesity epidemic.We analyzed the lifetime Northern Finland Birth Cohort 1986 (NFBC1986 (N = 4,032 to draw predictive equations for childhood and adolescent obesity from traditional risk factors (parental BMI, birth weight, maternal gestational weight gain, behaviour and social indicators, and a genetic score built from 39 BMI/obesity-associated polymorphisms. We performed validation analyses in a retrospective cohort of 1,503 Italian children and in a prospective cohort of 1,032 U.S. children.In the NFBC1986, the cumulative accuracy of traditional risk factors predicting childhood obesity, adolescent obesity, and childhood obesity persistent into adolescence was good: AUROC = 0·78[0·74-0.82], 0·75[0·71-0·79] and 0·85[0·80-0·90] respectively (all p<0·001. Adding the genetic score produced discrimination improvements ≤1%. The NFBC1986 equation for childhood obesity remained acceptably accurate when applied to the Italian and the U.S. cohort (AUROC = 0·70[0·63-0·77] and 0·73[0·67-0·80] respectively and the two additional equations for childhood obesity newly drawn from the Italian and the U.S. datasets showed good accuracy in respective cohorts (AUROC = 0·74[0·69-0·79] and 0·79[0·73-0·84] (all p<0·001. The three equations for childhood obesity were converted into simple Excel risk calculators for potential clinical use.This study provides the first example of handy tools for predicting childhood obesity in newborns by means of easily recorded information, while it shows that currently known genetic variants have very little usefulness for such prediction.

    Complete text of publication follows. Objective: In a report published in JAMA in 2004, Hujoel and colleagues indicated that maternal dental radiography during pregnancy may be associated with term low birth weight. Interestingly, they concluded that dental radiographies cause measurable radiation doses to the hypothalamus-pituitary-thyroid axis and the radiation effects on this axis is the reason for term low birth weight. On the other hand, low birth weight is the second leading cause of infant death. In this paper the results obtained in a 2 year study conducted at a midwifery hospital in Rafsanjan, IR Iran are reported. Methods: Four hundred seventy-five singleton infants with gestational periods of 37-44 wk born between 2006 and 2007 at the Niknafs Teaching Hospital affiliated with Rafsanjan University of Medical Sciences and met the inclusion criteria were enrolled in the study. Demographic data and clinical findings at birth including gestation age, sex of infant, birth order, season of birth, maternal age, and maternal education were collected from maternal and newborn hospital records and by interviews with parents. Maternal history of exposure to common sources of man-made ionizing and non-ionizing (exposure to radiations emitted by mobile phones, CRTs, cordless phones) radiation before and during pregnancy were carefully recorded. Results: Among the 475 infants who were studied, there were only 15 cases with a history of maternal dental radiography during pregnancy. The average newborn infants' birth weight in non-exposed and exposed (maternal dental radiography during pregnancy) groups were 3166.69±481.31 g and 3118.67±341.42 g respectively. This difference was not statistically significant. Conclusions: In this study, low birth weight was not associated with maternal dental radiography during pregnancy. These results are generally inconsistent with those reported by Hujoel and colleagues.

Prospective cohort of live births with gestational age of 23(0/7)-31(6/7) weeks, birth weight of 500-1499g without malformations, in 19 public maternity hospitals in nine capitals in northeastern Brazil from July to December 2007. The 19 hospitals were assessed in relation to physical resources, equipment, human resources and aiming at quality in care initiatives. Hospital, maternal and neonatal characteristics, neonatal morbidity, neonatal procedures and interventions were compared between preterm newborns that died or survived up to 24 hours of life. The variables associated with death within 24 hours after birth were determined by logistic regression. Of the 627 newborns enrolled in the study, 179 (29%) died within 168 hours after birth, of which 59 (33%) up to 24 hours and 97 (54%) up to 48 hours after birth.

    Full Text Available Abstract Background Triplets are often born premature and with a low birth weight. Because the incidence of triplet births is rare, there are relatively few studies describing triplet birth weight characteristics. Earlier studies are often characterized by small sample sizes and lack information on important background variables such as zygosity. The objective of this study is to examine factors associated with birth weight in a large, population-based sample of triplets registered with the Netherlands Twin Register (NTR. Methods In a sample of 1230 triplets from 410 families, the effects of assisted reproductive techniques, zygosity, birth order, gestational age, sex, maternal smoking and alcohol consumption during pregnancy on birth weight were assessed. The resemblance among triplets for birth weight was estimated as a function of zygosity. Birth weight discordance within families was studied by the pair-wise difference between triplets, expressed as a percentage of the birth weight of the heaviest child. We compare data from triplets registered with the NTR with data from population records, which include live births, stillbirths and children that have deceased within days after birth. Results There was no effect of assisted reproductive techniques on triplet birth weight. At gestational age 24 to 40 weeks triplets gained on average 130 grams per week; boys weighed 110 grams more than girls and triplets of smoking mothers weighted 104 grams less than children of non-smoking mothers. Monozygotic triplets had lower birth weights than di- and trizygotic triplets and birth weight discordance was smaller in monozygotic triplets than in di- and trizygotic triplets. The correlation in birth weight among monozygotic and dizygotic triplets was 0.42 and 0.32, respectively. In nearly two-thirds of the families, the heaviest and the lightest triplet had a birth weight discordance over 15%. The NTR sample is representative for the Dutch triplet

There is a need to study and identify the modifiable and non-modifiable risk factors determining birth weight. This will help in planning ante natal care more effectively. Materials and Methods : Study-type-cross-sectional study-setting: Hospital based. Study-subject: Mothers and their new borns. Sample size: All the births taken place during the study period. Study period: July 2010-June 2011. Study tools : (0 i Questionnaire. (ii pediatric weighing machine. Inclusion criteria : m0 others attending ante natal care (ANC clinic from 1 st trimester with minimum three antenatal visits, non-anemic at the end of 2 nd trimester, had full-term and singleton delivery. Exclusion criteria : H/O pregnancy induced hypertension (PIH, diabetes mellieutus (DM, tuberculosis (TB, urinary tract infection (UTI, delivered preterm and tobacco chewers or mishri users. Statistical Analysis : Percentages, mean and SD of birth weight, χ2 test, ANOVA, Z-test, and Binary logistic. Results: By using birth weight as a continuous data it was observed that birth-weight was significantly associated with maternal age (F = 3.360, df = 2, P = 0.035, education (F = 4.401, df = 4, P = 0.002 and breakfast (z = 3.970, P = 0.00. Proportion of LBW was 42.4%. For analysis, groups of newborns on the basis of birth weight showed significant association between LBW and maternal education (χ2 = 12.734, df = 4, P = 0.013, breakfast (χ2 = 13.241, df = 1, P = 0.00 and evening snacks (χ2 = 4.275, df = 1, P = 0.013. According to the binary logistic regression, breakfast and education were significant and best predictors for birth weight. Conclusion: Education and breakfast are strong determinants of birth-weight. Less educated women need more intense health education.

    Full Text Available Research question: What is the extent of low weight babies born in hospitals and its association with some maternal factors? Objectives: 1. To find an overall prevalence of low birth weight babies amongst hospital births in Meerut city. 2. To identify and quantify the effects of some risk factors for low birth weight. Setting: District women Hospital of Meerut city of western U.P. Study Design: Hospital based matched case-control study. Sample size: 491 low birth weight babies as ‘cases’ and an equal number of babies of normal birth weight in ‘control’ group matched for maternal age, sex of baby, birth order and institution of delivery. Study variables: Socio-economic Status: maternal biological factors including obstetric history: antenatal factors: nutritional factors: history of abortion: toxaemia of pregnancy etc. Results: Overall proportion of low birth weight babies was found to be 21.8% amongst hospital live births and 30.9% born to mothers aged below 30 years of age. Low maternal weight, under nutrition, lack of antenatal care, short inter-pregnancy interval, toxacmia of pregnancy were independent factors increasing the risk of low birth weight significantly. Conclusions: The study suggested that a substantial proportion of low birth weight babies can be averted by improving maternal nutritional status including anemic condition, birth spacing and proper antenatal care.

    Both gestation and birth weight have significant impact on mortality and morbidity in newborn infants. Nomograms at birth allow classification of infants into small for gestational age (SGA) and large for gestational age (LGA) categories, for risk stratification and more intensive monitoring. To date, the growth charts for preterm newborn infants in Singapore are based on the Fenton growth charts, which are constructed based on combining data from various Western growth cohorts. Hence, we aim to create Singapore nomograms for birth weight, length and head circumference at birth, which would reflect the norms and challenges faced by local infants. Growth parameters of all babies born or admitted to our unit from 2001 to 2012 were retrieved. Following exclusion of outliers, nomograms for 3 percentiles of 10th, 50th, and 90th were generated for the gestational age (GA) ranges of 25 to 42 weeks using quantile regression (QR) combined with the use of restricted cubic splines. Various polynomial models (second to third degrees) were investigated for suitability of fit. The optimum QR model was found to be a third degree polynomial with a single knotted cubic spline in the mid-point of the GA range, at 33.5 weeks. Check for goodness of fit was done by visual inspection first. Next, check was performed to ensure the correct proportion: 10% of all cases fall above the upper 90th percentile and 10% fall below the lower 10th percentile. Furthermore, an alternative formula-based method of nomogram construction, using mean, standard deviation (SD) and assumption of normality at each gestational age, was used for counterchecking. A total of 13,403 newborns were included in the analysis. The new infant-foetal growth charts with respect to birth weight, heel-crown length and occipitofrontal circumference from 25 to 42 weeks gestations with the 10th, 50th and 90th were presented. Nomograms for birth weight, length and head circumference at birth had significant impact on neonatal

    To study the impact of training of Traditional Birth Attendants (TBAs) on the Newborn care in resource poor setting in rural area. A community based study in the Primary Health Center (PHC) area was conducted over one year period between March 2006 to February 2007. The study participants were 50 Traditional Birth Attendants (TBAs)who conduct home deliveries in the PHC area. Training was conducted for two days which included topics on techniques of conducting safe delivery and newborn care practices. Pre-test evaluation regarding knowledge and practices about newborn care was done. Post-test evaluation was done at first month (early) and at fifth month (late) after the training. Analysis was done by using Mc. Nemer's test, Chi- square test with Yates's correction and Fischer's exact test. Pre-test evaluation showed that, knowledge and practices about newborn care services provided by the previously trained TBAs and untrained TBAs were poor. Early and late post-test evaluation showed that, there was a progressive improvement in the newborn care provided by both the groups. Preintervention period (one year prior to the training) and postintervention period (one year after the training) showed that, there was a statistically significant (p<0.05) reduction in the perinatal deaths (11 to 3) and neonatal deaths (10 to 2) among the deliveries conducted by TBAs after the training. Training programme for TBAs with regular reinforcements in the resource poor setting will not only improve the quality of newborn care but also reduces perinatal deaths.

    The fetal origins hypothesis emphasizes the life-long health impacts of prenatal conditions. Birth weight, birth length, and gestational age are indicators of the fetal environment. However, these variables often have missing data and are subject to random and systematic errors caused by delays in measurement, differences in measurement instruments, and human error. With data from the Cebu (Philippines) Longitudinal Health and Nutrition Survey, we use structural equation models, to explore random and systematic errors in these birth outcome measures, to analyze how maternal characteristics relate to birth outcomes, and to take account of missing data. We assess whether birth weight, birth length, and gestational age are influenced by a single latent variable that we call favorable fetal growth conditions (FFGC) and if so, which variable is most closely related to FFGC. We find that a model with FFGC as a latent variable fits as well as a less parsimonious model that has birth weight, birth length, and gestational age as distinct individual variables. We also demonstrate that birth weight is more reliably measured than is gestational age. FFGCs were significantly influenced by taller maternal stature, better nutritional stores indexed by maternal arm fat and muscle area during pregnancy, higher birth order, avoidance of smoking, and maternal age 20-35 years. Effects of maternal characteristics on newborn weight, length, and gestational age were largely indirect, operating through FFGC. Copyright © 2013 John Wiley & Sons, Ltd.

    Obesity during pregnancy increases the risk of adverse clinical outcomes and is associated with low-grade chronic inflammation. We describe maternal metabolic risk and inflammation by maternal weight status, and evaluate the association of metabolic and inflammatory markers with birthweight in a group of pregnant Mexican women. This study derived from a prospective cohort of healthy pregnant women gestation, receiving prenatal care at National Institute of Perinatology (Mexico, 2009-2013). Metabolic and inflammatory markers were measured in maternal serum in all three pregnancy trimesters (1st: 11.42±1.7; 2nd: 21.06±2.4; 3rd: 32.74±2.3 weeks). Pregestational weight was self-reported, and body mass index (BMI) was calculated. Gestational weight gain was evaluated in the third trimester. Newborn´s weight was measured at birth. We carried out correlations, general mixed linear model and regression analyses, based on pregestational weight (self-reported), body mass index (BMI), gestational weight gain (evaluated in the third trimester) and newborn weight (measured at birth). Of the 177 women included in the study (mean age = 26.93±8.49), thirty-eight percent (n = 67) were overweight or had obesity, and 32.8% (n = 58) showed excessive gestational weight gain. We found insulin, lipids (including total cholesterol, LDL-cholesterol, HDL-cholesterol, and triglycerides-TG), leptin and interleukin 1b (IL-1b) all increased significantly (pweight status altered longitudinal concentrations of insulin, leptin, adiponectin, TG and C reactive protein. Excessive gestational weight gain was associated with higher maternal insulin in the third trimester (pweight, but not in overweight or obese women. Maternal weight status affected the concentrations of insulin, leptin, adiponectin, triglycerides and C reactive protein throughout pregnancy. The role of early leptin and TNFα in fetal growth need further study given the association was only observed in normal weight women. This

    To determine the effects of infants' birth order, maternal age, and socioeconomic status (SES) on birth weight. This cross-sectional study included a sample of 858 mothers recruited over a 6-month period in 2010, in a defined population of 9 urban health centers, and who were admitted for their infants' first vaccination. Maternal clinical data, demographic data, and infants' birth weight were obtained from the interview and maternal hospital files. Multiple regression and analysis of variance were used for data analysis. First and fourth births had lower birth weights compared with second and third births in all maternal ages in controlling parity, birth weight increases with maternal age up to the early 24, and then tends to level off. Male gender, maternal age 20-24 years, second and third births had a significant positive effect on birth weight. Lower family economic status and higher educational attainment were significantly associated with lower birth weight. For women in the 15-19 and 40-44 years age groups, the second birth order was associated with the most undesirable effect on birth weight. Accessibility of health care services, parity, maternal age, and socioeconomic factors are strongly associated with infants' birth weight.

    In the United States, the high prevalence of unhealthy preconception body weight and inappropriate gestational weight gain among pregnant women is an important public health concern. However, the relationship among pre-pregnancy BMI, gestational weight gain, and newborn birth weight has not been well established. This study uses a very large dataset of sibling births and a within-family design to thoroughly address this issue. The baseline analysis controlling for mother fixed effects indicates maternal preconception overweight, preconception obesity, and excessive gestational weight gain significantly increase the risk of having a high birth weight baby, respectively, by 1.3, 3 and 3.9 percentage points, while underweight before pregnancy and inadequate gestational weight gain increase the low birth weight incidence by 1.4 and 2 percentage points. The benchmark results are robust in a variety of sensitivity checks. Since poor birth outcomes especially high birth weight and low birth weight have lasting adverse impacts on one's health, education, and socio-economic outcomes later in life, the findings of this research suggest promoting healthy weight among women before pregnancy and preventing inappropriate weight gain during pregnancy can generate significant intergenerational benefits.

    Full Text Available Background: Low birth weight remains a major reason behind childhood malnutrition. The NFHS findings show no dent in this problem. Objective: This study was undertaken to explore change in birth weights in a period from 1989 to 2007 and any associations thereof. Materials and Methods: All birth records of a private rural hospital spanning two decades (1989-2007 were analyzed for birth weight, age of mother, gender, birth order of the baby, proportion of pre-term babies and low birth weight babies. Results: No change was observed in the average birth weights (average 2.71 kg over the period. Although the birth weight shows some expected variance with the age of mother, it was found to have no relation with the baby′s birth order and gender. The low birth weight proportion is about 24% and shows little difference before and after the series midpoint of year 1998. Conclusion: The birth weights have hardly changed in this population in the two decades.

    In Uganda and elsewhere, the private sector provides an increasing and significant proportion of maternal and child health services. However, little is known whether private care results in better quality services and improved outcomes compared to the public sector, especially regarding care at the time of birth. To describe the characteristics of care-seekers and assess newborn care practices and services received at public and private facilities in rural eastern Uganda. Within a community-based maternal and newborn care intervention with health systems strengthening, we collected data from mothers with infants at baseline and endline using a structured questionnaire. Descriptive, bivariate, and multivariate data analysis comparing nine newborn care practices and three composite newborn care indicators among private and public health facilities was conducted. The proportion of women giving birth at private facilities decreased from 25% at baseline to 17% at endline, whereas overall facility births increased. Private health facilities did not perform significantly better than public health facilities in terms of coverage of any essential newborn care interventions, and babies were more likely to receive thermal care practices in public facilities compared to private (68% compared to 60%, p=0.007). Babies born at public health facilities received an average of 7.0 essential newborn care interventions compared to 6.2 at private facilities (pprivate facilities were more likely to have higher parity, lower socio-economic status, less education, to seek antenatal care later in pregnancy, and to have a normal delivery compared to women delivering in public facilities. In this setting, private health facilities serve a vulnerable population and provide access to service for those who might not otherwise have it. However, provision of essential newborn care practices was slightly lower in private compared to public facilities, calling for quality improvement in both

    Full Text Available Abstract Objective: To evaluate factors associated with neonatal death within 24 hours after birth in very low birth weight preterm newborns. Methods: Prospective cohort of live births with gestational age of 230/7–316/7 weeks, birth weight of 500–1499g without malformations, in 19 public maternity hospitals in nine capitals in northeastern Brazil from July to December 2007. The 19 hospitals were assessed in relation to physical resources, equipment, human resources and aiming at quality in care initiatives. Hospital, maternal and neonatal characteristics, neonatal morbidity, neonatal procedures and interventions were compared between preterm newborns that died or survived up to 24 hours of life. The variables associated with death within 24 hours after birth were determined by logistic regression. Results: Of the 627 newborns enrolled in the study, 179 (29% died within 168 hours after birth, of which 59 (33% up to 24 hours and 97 (54% up to 48 hours after birth. The variables associated with death <24h were: weight <1000g (2.94; 1.32–6.53, 5th minute Apgar <7 (7.17; 3.46–14.88, male gender (2.99; 1.39–6.47. A better hospital structure was a protective factor for early neonatal death (odds ratio: 0.34; 95% confidence interval: 0.17–0.71. Conclusions: The high neonatal mortality on the first day of life in capital cities of Northeast Brazil is associated with biological variables such as weight and gender of the newborn, as well as low vitality at birth and a worse infrastructure of the hospital where the birth occurred.

    Full Text Available Low birth weight (LBW is the most common cause of perinatal mortality, causing almost 30 percent of neonatal deaths. On the other hand, maternal short stature is known to cause a lot of obstetric complications like cephalopelvic disproportion and arrest of labor, intrauterine asphyxia, intrauterine growth retardation. The objective of our study was to find out whether there was any significant statistical association between maternal height and the birth weight of the neonate. We identified a group of low birth weight neonates (n=54 and a control group (n=51 of normal weight neonates at term in Mediciti Hospital over a period of 1 year and retrospectively looked the maternal heights for both groups. Inclusion criteria being mothers who delivered at term, mothers who had a hemoglobin level more than 10 gm/dl, mothers with relatively uneventful antenatal without any significant obstetric or medical complications during the pregnancy, and neonates with relatively uneventful post-natal periods without any significant pediatric or medical complications. The odds of having been born of a mother of short stature are more than three times greater for a low birth weight baby than a normal weight baby. The mean of birth weights of babies born to mothers of normal height is more than the mean of birth weights of babies born to mothers of short stature by 277.01 gm. This study reaffirms the observation that maternal height has a direct effect on the weight of the newborn and we propose that maternal short stature be identified as an independent risk factor for low birth weight.

    Full Text Available Introduction: Gestational diabetes mellitus (GDM is associated to increased rates of large for gestational age newborns and macrosomia. Several charts are used to classify birth weight. Is there an ideal chart to classify newborns of GDM mothers? Methods: We evaluated adequacy of birth weight of 332 neonates born to GDM mothers at Hospital de Clínicas de Porto Alegre, Brazil. Newborns were classified according to gestational age as small (SGA, adequate or large (LGA based on four charts: Alexander, Pedreira, INTERGROWTH 21st Project and SINASC-2012. The latter was built using data from a large national registry of 2012, the Born Alive National Surveillance System (Sistema de Informações de Nascidos Vivos – SINASC, which included 2.905,789 birth certificates. Frequencies of SGA and LGA and Kappa agreement were calculated. Results: In non-gender adjusted curves, SGA rates (95% confidence interval varied from 8% (5-11 to 9% (6-13; LGA rates, from 11% (8-15 to 17% (13-21. For males, SGA rates varied from 3% (1-6% to 6% (3-11%, and LGA rates, from 18% (13-24% to 31% (24-38%; for female, SGA rates were from 3% (1-7% to 10% (6-16% and LGA rates, from 11% (6-16% to 19% (13-26%. Kappa results were: ALEXANDER vs. SINASC-2012: 0.80 (0.73-0.88; INTERGROWTH 21st vs. SINASC-2012 (adjusted by sex: 0.62 (0.53-0.71; INTERGROWTH 21st vs. PEDREIRA: 0.71 (0.62-0.79; SINASC-2012 (by sex vs. PEDREIRA: 0.86 (0.79-0.93. Conclusions: Misclassification has to be taken into account when evaluating newborns of GDM mothers, as LGA rates can almost double depending on the chart used to classify birth weight.

    In 2006, WHO published international growth standards for children younger than 5 years, which are now accepted worldwide. In the INTERGROWTH-21(st) Project, our aim was to complement them by developing international standards for fetuses, newborn infants, and the postnatal growth period of preterm infants. INTERGROWTH-21(st) is a population-based project that assessed fetal growth and newborn size in eight geographically defined urban populations. These groups were selected because most of the health and nutrition needs of mothers were met, adequate antenatal care was provided, and there were no major environmental constraints on growth. As part of the Newborn Cross-Sectional Study (NCSS), a component of INTERGROWTH-21(st) Project, we measured weight, length, and head circumference in all newborn infants, in addition to collecting data prospectively for pregnancy and the perinatal period. To construct the newborn standards, we selected all pregnancies in women meeting (in addition to the underlying population characteristics) strict individual eligibility criteria for a population at low risk of impaired fetal growth (labelled the NCSS prescriptive subpopulation). Women had a reliable ultrasound estimate of gestational age using crown-rump length before 14 weeks of gestation or biparietal diameter if antenatal care started between 14 weeks and 24 weeks or less of gestation. Newborn anthropometric measures were obtained within 12 h of birth by identically trained anthropometric teams using the same equipment at all sites. Fractional polynomials assuming a skewed t distribution were used to estimate the fitted centiles. We identified 20,486 (35%) eligible women from the 59,137 pregnant women enrolled in NCSS between May 14, 2009, and Aug 2, 2013. We calculated sex-specific observed and smoothed centiles for weight, length, and head circumference for gestational age at birth. The observed and smoothed centiles were almost identical. We present the 3rd, 10th, 50th, 90

    Different pathways likely underlie the association between early weight gain and cardiovascular disease risk. We examined whether birth weight for length relationship and weight gain up to 2 years of age are associated with lipid profiles and blood pressure (BP) in early adolescence and determined whether childhood adiposity mediates these associations. Data from QUALITY (Quebec Adipose and Lifestyle Investigation in Youth), a cohort of white children with parental history of obesity, were analyzed (n=395). Sex-specific weight for length z scores from birth to 2 years were computed. Rate of postnatal weight gain was estimated using individual slopes of weight for length z -score measurements. Percentage of body fat was measured at 8 to 10 years. Fasting lipids and BP were measured at 10 to 12 years. Using path analysis, we found indirect effects of postnatal weight gain, through childhood adiposity, on all outcomes: Rate of postnatal weight for length gain was positively associated with childhood adiposity, which in turn was associated with unfavorable lipid and BP levels in early adolescence. In contrast, small beneficial direct effects on diastolic BP z scores, independent of weight at other time points, were found for birth weight for length (β=-0.05, 95% CI, -0.09 to -0.002) and for postnatal weight gain (β=-0.02, 95% CI, -0.03 to -0.002). Among children with at least 1 obese parent, faster postnatal weight gain leads to cardiovascular risk factors in early adolescence through its effect on childhood adiposity. Although heavier newborns may have lower BP in early adolescence, this protective direct effect could be offset by a deleterious indirect effect linking birth weight to later adiposity. © 2017 The Authors.

    newborn infants admitted to a Neonatal Intensive Care Unit from January 2007 to June 2010. Inborn infants weighing less than 1500g were eligible for the study. Maternal demographic variables, variables related to health conditions during pregnancy and delivery and variables related to newborn infants were collected. The association between variables was measured by chi-square test and Odds Ratio. Variables associated up to the level of 25% (p<0.25 in the bivariate analysis were included in the multivariate analysis by logistic regression, assuming a significance level of 5% (p<0.05. RESULTS: Data of 184 patients were analyzed, and 44 (23.9% of them died. The variables that remained statistically associated with death in very low birth weight infants after the multivariate analysis were: birth weight below 1000g (OR 7.29; 95%CI 3.19 - 16.63; p<0.001, Apgar Score at the 1st minute <7 (OR 3.57; 95%CI 1.53 - 8.32, p=0.003, and report of less than four prenatal visits (OR 2.72; 95%CI 1.19 - 6.23, p=0.018. CONCLUSIONS: The results show gaps in prenatal care and the need for perinatal care improvement addressed to both mothers and infants.

    BackgroundWe aimed to describe newborn body composition and identify which anthropometric ratio (weight/length; BMI; or ponderal index, PI) best predicts fat mass (FM) and fat-free mass (FFM).MethodsAir-displacement plethysmography (PEA POD) was used to estimate FM, FFM, and body fat percentage (BF%). Associations between FFM, FM, and BF% and weight/length, BMI, and PI were evaluated in 1,019 newborns using multivariate regression analysis. Charts for FM, FFM, and BF% were generated using a prescriptive subsample (n=247). Standards for the best-predicting anthropometric ratio were calculated utilizing the same population used for the INTERGROWTH-21 st Newborn Size Standards (n=20,479).ResultsFFM and FM increased consistently during late pregnancy. Differential FM, BF%, and FFM patterns were observed for those born preterm (34 +0 -36 +6 weeks' gestation) and with impaired intrauterine growth. Weight/length by gestational age (GA) was a better predictor of FFM and FM (adjusted R 2 =0.92 and 0.71, respectively) than BMI or PI, independent of sex, GA, and timing of measurement. Results were almost identical when only preterm newborns were studied. We present sex-specific centiles for weight/length ratio for GA.ConclusionsWeight/length best predicts newborn FFM and FM. There are differential FM, FFM, and BF% patterns by sex, GA, and size at birth.

    Introduction It has been established that underweight women with low gestational weight gain (GWG) are at a higher risk of having Small for Gestational Age (SGA) newborns. However, the association remains poorly studied in Middle Eastern societies exhibiting different ethnic groups, genetic predisposing factors along with differences in nutritional food intake during pregnancy. The aim of this study is to assess the risk of having a SGA newborn among underweight and normal weight BMI women while studying the role of GWG in this association. Methods This is a retrospective cross-sectional study of 62,351 singleton pregnancies from the National Collaborative Perinatal Neonatal Network between 2001 and 2009 from 27 hospitals across Lebanon. Women who had underweight and normal pre-pregnancy BMI were included. Results A total of 8.6% newborns were SGA and 6.6% of women were underweight. Among women with normal and underweight pre-pregnancy BMI, 8.6 and 12.4% had SGA births respectively. Overall, the adjusted OR of having SGA newborns was significantly higher among underweight women (OR = 1.448; 95%CI = 1.287-1.630) compared to normal pre-pregnancy BMI. Below normal weight gain significantly increased the odds of SGA for both normal and underweight pre-pregnancy BMI women, with adjusted ORs of 1.535 (95% CI = 1.418-1.661) and 1.970 (95%CI = 1.515-2.560) respectively. Discussion Higher risks of SGA newborns in underweight and normal BMI women with low GWG were observed. In addition, normal weight gain couldn't protect underweight women of having risk for SGA newborns. Hence, all pregnant women should be encouraged to maintain healthy BMI before pregnancy and attain adequate GWG.

    This paper aims to identify health research priorities that could improve the rate of progress in reducing global neonatal mortality from preterm birth and low birth weight (PB/LBW), as set out in the UN's Millennium Development Goal 4. We applied the Child Health and Nutrition Research Initiative (CHNRI) methodology for setting priorities in health research investments. In the process coordinated by the World Health Organization in 2007-2008, 21 researchers with interest in child, maternal and newborn health suggested 82 research ideas that spanned across the broad spectrum of epidemiological research, health policy and systems research, improvement of existing interventions and development of new interventions. The 82 research questions were then assessed for answerability, effectiveness, deliverability, maximum potential for mortality reduction and the effect on equity using the CHNRI method. The top 10 identified research priorities were dominated by health systems and policy research questions (eg, identification of LBW infants born at home within 24-48 hours of birth for additional care; approaches to improve quality of care of LBW infants in health facilities; identification of barriers to optimal home care practices including care seeking; and approaches to increase the use of antenatal corticosteriods in preterm labor and to improve access to hospital care for LBW infants). These were followed by priorities for improvement of the existing interventions (eg, early initiation of breastfeeding, including feeding mode and techniques for those unable to suckle directly from the breast; improved cord care, such as chlorhexidine application; and alternative methods to Kangaroo Mother Care (KMC) to keep LBW infants warm in community settings). The highest-ranked epidemiological question suggested improving criteria for identifying LBW infants who need to be cared for in a hospital. Among the new interventions, the greatest support was shown for the development of

Although intuitively appealing, the incremental value they provide in the identification of intrauterine growth restriction (IUGR) over conventional birth weight percentiles is controversial. The objective of this study was to assess the value of customized birth weight percentiles in a simulated cohort of 100,000 infants aged 37 weeks whose IUGR status was known. A cohort of infants with a range of healthy birth weights was first simulated on the basis of the distributions of maternal/fetal characteristics observed in births at the Royal Victoria Hospital in Montreal, Canada, between 2000 and 2006. The occurrence of IUGR was re-created by reducing the observed birth weights of a small percentage of these infants. The value of customized percentiles was assessed by calculating true and false positive rates. Customizing birth weight percentiles for maternal characteristics added very little information to the identification of IUGR beyond that obtained from conventional weight-for-gestational-age percentiles (true positive rates of 61.8% and 61.1%, respectively, and false positive rates of 7.9% and 8.5%, respectively). For the process of customization to be worthwhile, maternal characteristics in the customization model were shown through simulation to require an unrealistically strong association with birth weight.

    To examine the association of sociodemographic, antenatal and delivery care factors with the essential newborn care (ENC) practices of neonates born at home in Bangladesh. This study analyzed data of a cross-sectional survey-the Bangladesh Demographic and Health Survey, 2011. This analysis considered 3190 most recent live-born infants who were delivered at home within three years of the survey. Logistic regression models were used to identify the factors affecting the implementation of six ENC practices, namely using disinfected instruments to cut the umbilical cord, avoidance of application of any substances to the umbilical cord stump, immediate drying and wrapping of newborns, delayed bathing of newborns, and immediate initiation of breastfeeding. Factors affecting ENC practices in Bangladesh are low parental education, low utilization of antenatal care services, the absence of skilled birth attendants, smaller size at birth, higher birth order and mother's age at birth. Regional factors also seem to considerably affect ENC practices. There is ample scope to improve the coverage of ENC practices in Bangladesh. Health promotion programmes that target parents with low education and older mothers may help to build awareness of ENC practices. This investigation provides insight into the key determinants of ENC practices, which require consideration when scaling up ENC practices in low-income and lower middle-income countries.

    2012-02-01

    OBJECTIVE: To identify the maternal body composition parameters that independently influence birth weight. STUDY DESIGN: A longitudinal prospective observational study in a large university teaching hospital. One hundred and eighty-four non-diabetic caucasian women with a singleton pregnancy were studied. In early pregnancy maternal weight and height were measured digitally in a standardised way and the body mass index (BMI) was calculated. At 28 and 37 weeks\\' gestation maternal body composition was assessed using segmental multifrequency bioelectrical impedance analysis. At delivery the baby was weighed and the clinical details were recorded. RESULTS: Of the women studied, 29.2% were overweight and 34.8% were obese. Birth weight did not correlate with maternal weight or BMI in early pregnancy. Birth weight correlated with gestational weight gain (GWG) before the third trimester (r=0.163, p=0.027), but not with GWG in the third trimester. Birth weight correlated with maternal fat-free mass, and not fat mass at 28 and 37 weeks gestation. Birth weight did not correlate with increases in maternal fat and fat-free masses between 28 and 37 weeks. CONCLUSIONS: Contrary to previous reports, we found that early pregnancy maternal BMI in a non-diabetic population does not influence birth weight. Interestingly, it was the GWG before the third trimester and not the GWG in the third trimester that influenced birth weight. Our findings have implications for the design of future intervention studies aimed at optimising gestational weight gain and birth weight. CONDENSATION: Maternal fat-free mass and gestational weight gain both influence birth weight.

    Full Text Available Previous studies have shown that woman's risk of breast cancer in later life is associated with her infants birth weights. The objective of this study was to determine if this association is independent of breast cancer risk factors, mother's own birth weight and to evaluate association between infants birth weight and hormonal environment during pregnancy. Independent association would have implications for understanding the mechanism, but also for prediction and prevention of breast cancer.Risk of breast cancer in relation to a first infant's birth weight, mother's own birth weight and breast cancer risk factors were evaluated in a prospective cohort of 410 women in the Framingham Study. Serum concentrations of estriol (E3, anti-estrogen alpha-fetoprotein (AFP, and pregnancy-associated plasma protein-A (PAPP-A were measured in 23,824 pregnant women from a separate prospective cohort, the FASTER trial. During follow-up (median, 14 years 31 women (7.6% were diagnosed with breast cancer. Women with large birth weight infants (in the top quintile had a higher breast cancer risk compared to other women (hazard ratio (HR, 2.5; 95% confidence interval (CI, 1.2-5.2; P = 0.012. The finding was not affected by adjustment for birth weight of the mother and traditional breast cancer risk factors (adjusted HR, 2.5; 95% CI, 1.2-5.6; P = 0.021. An infant's birth weight had a strong positive relationship with the mother's serum E3/AFP ratio and PAPP-A concentration during pregnancy. Adjustment for breast cancer risk factors did not have a material effect on these relationships.Giving birth to an infant with high birth weight was associated with increased breast cancer risk in later life, independently of mother's own birth weight and breast cancer risk factors and was also associated with a hormonal environment during pregnancy favoring future breast cancer development and progression.

    The impact of maternal height, pre-pregnancy weight status and gestational weight gain on fetal growth patterns and newborn size was analysed using a dataset of 4261 singleton term births taking place at the Viennese Danube Hospital between 2005 and 2013. Fetal growth patterns were reconstructed from three ultrasound examinations carried out at the 11th/12th, 20th/21th and 32th/33th weeks of gestation. Crown-rump length, biparietal diameter, fronto-occipital diameter, head circumference, abdominal transverse diameter, abdominal anterior-posterior diameter, abdominal circumference and femur length were determined. Birth weight, birth length and head circumference were measured immediately after birth. The vast majority of newborns were of normal weight, i.e. between 2500 and 4000 g. Maternal height showed a just-significant but weak positive association (r=0.03: p=0.039) with crown-rump length at the first trimester and with the majority of fetal parameters at the second trimester (r>0.06; p0.09; p0.08; p0.17; p0.13; p0.13; pnewborn size. Some of these associations were quite weak and the statistical significance was mainly due to the large sample size. The association patterns between maternal height and pre-pregnancy weight status with fetal growth patterns (pnewborn size (p<0.001), were independent of maternal age, nicotine consumption and fetal sex. In general, taller and heavier women gave birth to larger infants. This association between maternal size and fetal growth patterns was detectable from the first trimester onwards.

    2009-04-01

    Full Text Available Abstract Background Low birth weight has been related to an increased risk for developing high blood pressure in adult life. The molecular and cellular analysis of umbilical cord artery and vein may provide information about the early vascular characteristics of an individual. We have assessed several phenotype characteristics of the four vascular cell types derived from human umbilical cords of newborns with different birth weight. Further follow-up studies could show the association of those vascular properties with infancy and adulthood blood pressure. Methods Endothelial and smooth muscle cell cultures were obtained from umbilical cords from two groups of newborns of birth weight less than 2.8 kg or higher than 3.5 kg. The expression of specific endothelial cell markers (von Willebrand factor, CD31, and the binding and internalization of acetylated low-density lipoprotein and the smooth muscle cell specific α-actin have been evaluated. Cell culture viability, proliferation kinetic, growth fraction (expression of Ki67 and percentage of senescent cells (detection of β-galactosidase activity at pH 6.0 have been determined. Endothelial cell projection area was determined by morphometric analysis of cell cultures after CD31 immunodetection. Results The highest variation was found in cell density at the confluence of endothelial cell cultures derived from umbilical cord arteries (66,789 ± 5,093 cells/cm2 vs. 45,630 ± 11,927 cells/cm2, p 2, p Conclusion The analysis of umbilical cord artery endothelial cells, which demonstrated differences in cell size related to birth weight, can provide hints about the cellular and molecular links between lower birth weight and increased adult high blood pressure risk.

    Full Text Available Abstract Background Malaria has a negative effect on pregnancy outcome, causing low birth weight, premature birth and stillbirths, particularly in areas with high malaria transmission. In Rwanda, malaria transmission intensity ranges from high to nil, probably associated with variable altitudes. Overall, the incidence decreased over the last six years (2002–2007. Therefore, the impact of malaria on birth outcomes is also expected to vary over time and space. Methods Obstetric indicators (birth weight and pregnancy outcome and malaria incidence were compared and analyzed to their association over time (2002–2007 and space. Birth data from 12,526 deliveries were collected from maternity registers of 11 different primary health centers located in different malaria endemic areas. Malaria data for the same communities were collected from the National Malaria Control Programme. Associations were sought with mixed effects models and logistic regression. Results In all health centres, a significant increase of birth weight over the years was observed (p Conclusion In Rwanda, birth weight and pregnancy outcome are not directly influenced by malaria, which is in contrast to many other studied areas. Although malaria incidence overall has declined and mean birth weight increased over the studied period, no direct association was found between the two. Socio-economic factors and improved nutrition could be responsible for birth weight changes in recent years.

    CONTEXT: Low birth weight has been proposed as a risk factor for the development of antibodies toward thyroid peroxidase (TPOAb) and thyroglobulin (TgAb) in adult life. However, the association could also be due to genetic or environmental factors affecting both birth weight and the development...... of thyroid autoantibodies. The effect of these confounders can be minimized through investigation of twin pairs.

    Hearing plays an essential role in the acquisition, development and maintenance of the properties of the speech and language. Birth weight is an indicator of biological maturation of the newborn. Premature newborns with very low birth weight (VLBW<1,500 g) constitute a group with the highest risk of sensorineural hearing loss. Our objective was to ascertain the degree of hearing loss, sensorineural hearing loss and presence of the association to other risk factors for hearing loss in VLBW infants included in the Universal Hearing Loss Screening Programme at the University Mother-Child Hospital of Gran Canaria (Spain) in the 2007-2010 period. This was a retrospective study of 364 infants with VLBW, measured by transient evoked otoacoustic emissions and auditory brainstem response. There were 112 newborn (30.8%) referred for auditory brainstem response. A diagnosis of hearing loss was given to 22 newborns (2.2%), 14 had conductive hearing loss and 8, sensorineural hearing loss (SNHL), of which 2 had bilateral profound hearing loss. The VLBW newborn presented the association to another risk factor in more than a quarter of the sample studied. All those diagnosed with SNHL were premature. The percentage of VLBW newborns diagnosed with hearing loss is higher than expected in the general population. All those diagnosed with SNHL were premature and presented one or 2 hearing risk factors associated with VLBW. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    Full Text Available For many years endotracheal intubation and mechanical ventilation have been the standard of care for very low birth weight infants but, in the last decade, nasal continuous positive airway pressure (nCPAP has been described in many studies as an option for the treatment of preterm infants with respiratory distress syndrome. In fact, recent studies have shown that early nCPAP is not associated with higher rates of morbidity and mortality and does not imply more days of ventilation support when compared to traditional ventilation techniques. The authors conducted a study to compare the outcomes (in terms of mortality, morbidity and need for medical support of very low birth weight infants treated with nCPAP or endotracheal intubation and mechanical ventilation. One hundred and four newborns were enrolled in this study, 44 (42.3% were treated with nCPAP and 60 (57.7% with endotracheal intubation followed by mechanical ventilation. A subgroup analysis of newborns with gestational age between 28 and 31 weeks was also performed. It included 57 newborns with similar demographic characteristics, 29 (50.9% treated with nCPAP and 28 (49.1% with endotracheal intubation followed by mechanical ventilation. No statistically significant differences were found in the frequency of death or bronchopulmonary dysplasia. Statistically significant differences were found in the prevalence of hyaline membrane disease (p = 0.033 and surfactant administration (p = 0.021 with lower rates in the nCPAP group. No other differences were found in the prevalence of other morbidities or in the need for medical support after birth. These results suggests that nCPAP might be chosen as primary ventilatory support choice in very low birth weight preterm, when there are no contraindications to its use.

    Infants born with complete atrioventricular block (CAVB) and fetal bradycardia are frequently born with low birth weight. Three low-birth-weight CAVB infants underwent temporary pacemaker implantation, followed by permanent single-chamber pacemaker implantation at median body weights of 1.7 and 3.2 kg, respectively. All infants caught up with their growth curves and had >3 years of estimated residual battery life. This two-stage strategy was successful in facilitating permanent pacemaker implantation in low-birth-weight babies. Placement of single-chamber pacemaker on the apex of the left ventricle appears to be associated with longer battery lifespan. © 2018 Wiley Periodicals, Inc.

    Full Text Available Background: In Uganda and elsewhere, the private sector provides an increasing and significant proportion of maternal and child health services. However, little is known whether private care results in better quality services and improved outcomes compared to the public sector, especially regarding care at the time of birth. Objective: To describe the characteristics of care-seekers and assess newborn care practices and services received at public and private facilities in rural eastern Uganda. Design: Within a community-based maternal and newborn care intervention with health systems strengthening, we collected data from mothers with infants at baseline and endline using a structured questionnaire. Descriptive, bivariate, and multivariate data analysis comparing nine newborn care practices and three composite newborn care indicators among private and public health facilities was conducted. Results: The proportion of women giving birth at private facilities decreased from 25% at baseline to 17% at endline, whereas overall facility births increased. Private health facilities did not perform significantly better than public health facilities in terms of coverage of any essential newborn care interventions, and babies were more likely to receive thermal care practices in public facilities compared to private (68% compared to 60%, p=0.007. Babies born at public health facilities received an average of 7.0 essential newborn care interventions compared to 6.2 at private facilities (p<0.001. Women delivering in private facilities were more likely to have higher parity, lower socio-economic status, less education, to seek antenatal care later in pregnancy, and to have a normal delivery compared to women delivering in public facilities. Conclusions: In this setting, private health facilities serve a vulnerable population and provide access to service for those who might not otherwise have it. However, provision of essential newborn care practices was

    Objective: To identify factors affecting birth weight and pre-term birth, and to find associations with electromagnetic devices such as television, computer and mobile phones. Methods: The study was conducted in Turkey at Gazintep University, Faculty of Medicine Outpatient Clinic at the Paediatric Ward. It comprised 500 patients who presented at the clinic from May to December 2009. All participants were administered a questionnaire regarding their pregnancy history. SPSS 13 was used for statistical analysis. Results: In the study, 90 (19%) patients had pre-term birth , and 64 (12.9%) had low birth weight rate Birth weight was positively correlated with maternal age and baseline maternal weight (r= 0.115, p= 0.010; r= 0.168, p=0.000, respectively). Pre-term birth and birth weight less than 2500g were more common in mothers with a history of disease during pregnancy (p=0.046 and p=0.008, respectively). The habit of watching television and using mobile phones and computer by mothers did not demonstrate any relationship with birth weight. Mothers who used mobile phones or computers during pregnancy had more deliveries before 37 weeks (p=0.018, p=0.034; respectively). Similarly, pregnancy duration was shorter in mothers who used either mobile phone or computers during pregnancy (p=0.005, p=0.048, respectively). Conclusion: Mobile phones and computers may have an effect on pre-term birth. (author)

    A survey was carried out in Ribeirão Preto, S. Paulo State, Brazil, between June 1978 and May 1979 with a view to studying the prevalence of low birth weight and its occurrence among different social classes. Data were collected from 8,878 singleton live births in eight maternity hospitals, accounting for 98% of all births in the area. Social classes were determinated by the use of a model proposed by Singer and modified for epidemiological purposes by Barros. Out of the 8,878 births, 660 (7.5%) were of low birth weight. The prevalence of deficient weight at birth (between 2,500 and 2,999 grams) was of 21.1%. Analysis indicated that 50.6% of children with low birth weight were at term and the majority of them suffered form intrauterine growth retardation. The prevalence of low birth weight according to social class was seen to be lower in the bourgeoisie classes (ranging from 2.8% to 3.9%) and higher in working classes (from 7% up to 9.5%). Low birth weight (defined as less than or equal to 2,500 grams) was used for purposes of comparison with other previous surveys. The percentage was lower in this study (8.3%) than that found in the Interamerican Investigation of Mortality in Childhood (8.7%), carried out in 1968-70. No statistically significant differences in the percentage of low birth weight were found in the case of Ribeirão Preto when these two surveys were compared.

    Cathrine Wildenschild

    Full Text Available To examine the association between a woman's birth weight and her subsequent fecundability.In this prospective cohort study, we included 2,773 Danish pregnancy planners enrolled in the internet-based cohort study "Snart-Gravid", conducted during 2007-2012. Participants were 18-40 years old at study entry, attempting to conceive, and were not receiving fertility treatment. Data on weight at birth were obtained from the Danish Medical Birth Registry and categorized as <2,500 grams, 2,500-2,999 grams, 3,000-3,999 grams, and ≥ 4,000 grams. In additional analyses, birth weight was categorized according to z-scores for each gestational week at birth. Time-to-pregnancy measured in cycles was used to compute fecundability ratios (FR and 95% confidence intervals (CI, using a proportional probabilities regression model.Relative to women with a birth weight of 3,000-3,999 grams, FRs adjusted for gestational age, year of birth, and maternal socio-demographic and medical factors were 0.99 (95% CI: 0.73;1.34, 0.99 (95% CI: 0.87;1.12, and 1.08 (95% CI: 0.94;1.24 for birth weight <2,500 grams, 2,500-2,999 grams, and ≥ 4,000 grams, respectively. Estimates remained unchanged after further adjustment for markers of the participant's mother's fecundability. We obtained similar results when we restricted to women who were born at term, and to women who had attempted to conceive for a maximum of 6 cycles before study entry. Results remained similar when we estimated FRs according to z-scores of birth weight.Our results indicate that birth weight appears not to be an important determinant of fecundability.

    We examined the associations between birth weight and intelligence at 3 different adult ages. The Copenhagen Perinatal Cohort is comprised of children born in Copenhagen from 1959 to 1961. Information on birth weight and ≥1 tests of intelligence was available for 4696 members of the cohort. Intelligence was assessed at a mean age of 19 years with the Børge Priens Prøve test, at age 28 years with the Wechsler Adult Intelligence Scale, and at age 50 years with the Intelligenz-Struktur-Test 2000 R. Birth weight was significantly associated with intelligence at all 3 follow-up assessments, with intelligence scores increasing across 4 birth weight categories and declining for the highest birth weight category. The adjusted differences between those in the 5 IQ points at all 3 follow-up assessments, corresponding to one-third of a SD. The association was stable from young adulthood into midlife,and not weaker at age 50 years. Adjustment for potential confounding factors, including infant socioeconomic status and gestational age, did not dilute the associations, and associations with intelligence were evident across the normal birth weight range and so were not accounted for by low birth weight only. The association between birth weight and intelligence is stable from young adulthood into midlife. These long-term cognitive consequences may imply that even small shifts in the distribution of birth size, in normal-sized infants as well, may have a large impact at the population level.

    Intake of colostrum after birth is essential to stimulate intestinal growth and function, and to provide systemic immunological protection via absorption of Immunoglobulin G (IgG). The birth order and weight of 745 piglets (from 75 litters) were recorded during a one-week period of farrowing. Only pigs weighing greater than 0.68 kg birth weight were chosen for the trial. Sow colostrum was collected during parturition, and piglets were bled between 48 and 72 hours post-birth. Piglet serum IgG and colostral IgG concentrations were determined by radial immunodiffusion. Sow parity had a significant (P birth order accounted for another 4% of the variation observed in piglet serum IgG concentration (P birth weight had no detectable effect. Piglet serum IgG concentration had both a linear (P Birth order had no detectable effect on survival, but birth weight had a positive linear effect (P birth had a 68% survival rate, and those weighing 1.6 kg (n = 158) had an 89% survival. We found that the combination of sow colostrum IgG concentration and birth order can account for 10% of the variation of piglet serum IgG concentration and that piglets with less than 1,000 mg/dl IgG serum concentration and weight of 0.9 kg at birth had low survival rate when compared to their larger siblings. The effective management of colostrum uptake in neonatal piglets in the first 24 hrs post-birth may potentially improve survival from birth to weaning.

Methods: a retrospective study of patients in labor and newborns from Hospital Santa Lucinda since 03/2009 to 02/2010: 19 of the study group (low weight and 50 of the control group (normal weight. The maternal variables included were: age, parity, puerperium; in the newborns were observed: sex, vitality, anthropometrics values, and outcomes. The statistical analysis involved the use Bioestat 5.0 program. Results: the middle perimeter head of newborns from low weight patients were 33,3 cm, and in the control group were 33,7 cm (p = 0,098; middle left arm perimeter were 10,0 cm and 10,3 cm (p = 0, 097; average weight: 2986,84 and 3165,32 g (p = 0, 0423, average length: 48,37 and 48, 77 cm (p = 0,2165 respectively. The average vitality from newborns after 1 and 5 minutes were: 8,1 - 8,1 (p = 0,9144 and 8,9 - 9,0 (p = 0,911. Conclusion: the weights of newborns from low weight patients in labor denote lower than normal weight patients. Low weight patients signify a risk group during the prenatal care, because there is more probability to be born low weight newborns. Prophylactics educating programs must be realized in order to avoid probable risks in low weight pregnant patients. Support PIBIC - CEPE

    To evaluate the impact of birth attendant training using the World Health Organization Essential Newborn Care (ENC) course among traditional birth attendants, with a particular emphasis on the effect of acquisition of skills on perinatal outcomes. Population-based, prospective, interventional pre-post design study. 11 rural clusters in Chimaltenango, Guatemala. Health care providers. This study analyzed the effect of training and implementation of the ENC health care provider training course between September 2005 and December 2006. The primary outcome measure was the rate of death from all causes in the first seven days after birth in fetuses/infants ≥1500g. Secondary outcome measures were overall rate of stillbirth, rate of perinatal death, which included stillbirths plus neonatal deaths in the first seven days in fetuses/infants ≥1500g. Perinatal mortality decreased from 39.5/1000 pre-ENC to 26.4 post-ENC (RR 0.72; 95%CI 0.54-0.97). This reduction was attributable almost entirely to a decrease in the stillbirth rate of 21.4/1000 pre-Essential Newborn Care to 7.9/1000 post-ENC (RR 0.40; 95%CI 0.25-0.64). Seven-day neonatal mortality did not decrease (18.3/1000 to 18.6/1000; RR 1.05; 95%CI 0.70-1.57). Essential Newborn Care training reduced stillbirths in a population-based controlled study with deliveries conducted almost exclusively by traditional birth attendants. Scale-up of this intervention in other settings might help assess reproducibility and sustainability. © Published [2012].

    Full Text Available Birth weight can be a predictor of maternal health issues related to nutrition and environmental contaminants. Total hair mercury (HHg concentration was studied as an indicator of both fish consumption and methylmercury exposure in mothers (and newborns living in selected low income areas of the Madeira River basin, Amazonia, Brazil. This cohort study (n = 1,433 consisted of traditional riverines (n = 396, riverines who had moved to urban (n = 676 and rural (n = 67 settings, and tin miner settlers (n = 294. Median maternal HHg was significantly different (p = 0.00001 between riverine (12.1 µg·g−1, rural (7.82 µg·g−1, urban (5.4 µg·g−1, and tin miner (4.5 µg·g−1 groups studied. The same trend (of medians was observed for newborns’ HHg which also showed significant differences between riverine (3.0 µg·g−1, rural (2.0 µg·g−1, urban (1.5 µg·g−1, and tin miner (0.8 µg·g−1 groups. The correlation between maternal and newborn HHg was statistically significant in the riverine (r = 0.8952; p = 0.0001, urban (r = 0.6744; p = 0.0001, and rural (r = 0.8416; p = 0.0001 groups but not in the mother-infant pairs in the tin miner group (r = 0.0638; p = 0.2752. Birth weight was significantly different among groups but did not show a pattern consistent with that of fish consumption (and HHg. A multiple regression analysis showed that only family income and gestational age had a significant impact on birth weight. Conclusions: Maternal HHg is an important biomarker of maternal fish consumption and of methylmercury exposure during pregnancy. However, in these Amazonian groups, only maternal education and gestational age seemed to affect birth weight positively.

    Whether the type of culture media utilized in assisted reproductive technology has impacts on laboratory outcomes and birth weight of newborns in in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) was investigated. A total of 673 patients undergoing IVF/ICSI and giving birth to live singletons after fresh embryo transfer on day 3 from Jan. 1, 2010 to Dec. 31, 2012 were included. Three types of culture media were used during this period: Quinn's Advantage (QA), Single Step Medium (SSM), and Continuous Single Culture medium (CSC). Fertilization rate (FR), normal fertilization rate (NFR), cleavage rate (CR), normal cleavage rate (NCR), good-quality embryo rate (GQER) and neonatal birth weight were compared using one-way ANOVA and χ (2) tests. Multiple linear regression analysis was performed to determine the impact of culture media on laboratory outcomes and birth weight. In IVF cycles, GQER was significantly decreased in SSM medium group as compared with QA or CSC media groups (63.6% vs. 69.0% in QA; vs. 71.3% in CSC, P=0.011). In ICSI cycles, FR, NFR and CR were significantly lower in CSC medium group than in other two media groups. No significant difference was observed in neonatal birthweight among the three groups (P=0.759). Multiple linear regression analyses confirmed that the type of culture medium was correlated with FR, NFR, CR and GQER, but not with neonatal birth weight. The type of culture media had potential influences on laboratory outcomes but did not exhibit an impact on the birth weight of singletons in ART.

    Neonates born to overweight or obese women are larger and at higher risk of birth complications. Many maternal obesity-related traits are observationally associated with birth weight, but the causal nature of these associations is uncertain. To test for genetic evidence of causal associations of maternal body mass index (BMI) and related traits with birth weight. Mendelian randomization to test whether maternal BMI and obesity-related traits are potentially causally related to offspring birth weight. Data from 30,487 women in 18 studies were analyzed. Participants were of European ancestry from population- or community-based studies in Europe, North America, or Australia and were part of the Early Growth Genetics Consortium. Live, term, singleton offspring born between 1929 and 2013 were included. Genetic scores for BMI, fasting glucose level, type 2 diabetes, systolic blood pressure (SBP), triglyceride level, high-density lipoprotein cholesterol (HDL-C) level, vitamin D status, and adiponectin level. Offspring birth weight from 18 studies. Among the 30,487 newborns the mean birth weight in the various cohorts ranged from 3325 g to 3679 g. The maternal genetic score for BMI was associated with a 2-g (95% CI, 0 to 3 g) higher offspring birth weight per maternal BMI-raising allele (P = .008). The maternal genetic scores for fasting glucose and SBP were also associated with birth weight with effect sizes of 8 g (95% CI, 6 to 10 g) per glucose-raising allele (P = 7 × 10(-14)) and -4 g (95% CI, -6 to -2 g) per SBP-raising allele (P = 1×10(-5)), respectively. A 1-SD ( ≈ 4 points) genetically higher maternal BMI was associated with a 55-g higher offspring birth weight (95% CI, 17 to 93 g). A 1-SD ( ≈ 7.2 mg/dL) genetically higher maternal fasting glucose concentration was associated with 114-g higher offspring birth weight (95% CI, 80 to 147 g). However, a 1-SD ( ≈ 10 mm Hg) genetically higher maternal SBP was associated with a 208-g

    We examined the association between sports and other leisure-time physical activities during pregnancy and birth weight of babies born after 37 completed weeks of gestation. All Danish-speaking pregnant women attending routine antenatal care at the Department of Obstetrics, Aarhus University Hospital, Denmark, from August 1989 to September 1991 were invited to participate in the study. A total of 4458 healthy women who delivered after 37 completed gestational weeks participated in this study. The associations between sports (0, 1-2, 3+ h/week) or leisure-time physical activity (sedentary, light, and moderate to heavy) and birth weight were examined by linear and logistic regression and adjusted for potential confounding factors such as smoking, parity, schooling, pre-pregnancy body mass index and gestational age. The results showed that pregnant women who practiced sports or were moderate to heavy leisure-time physical active during the early second or the early third trimester gave birth to infants with a similar birth weight as inactive women. The proportion of newborns with a low (/=4500 g) was also unchanged. In conclusion, in this large population-based study, we found no association between sports and leisure-time physical activity and low-birth weight, high-birth weight, or average-birth weight.

    Abstract The present study had 2 objectives, first, to investigate possible relationships between increased gestational weight gain and demographic, clinical, paraclinical, genetic, and bioimpedance (BIA) characteristics of Romanian mothers, and second, to identify the influence of predictors (maternal and newborns characteristics) on our outcome birth weight (BW). We performed a cross-sectional study on 309 mothers and 309 newborns from Romania, divided into 2 groups: Group I—141 mothers with high gestational weight gain (GWG) and Group II—168 mothers with normal GWG, that is, control group. The groups were evaluated regarding demographic, anthropometric (body mass index [BMI], middle upper arm circumference, tricipital skinfold thickness, weight, height [H]), clinical, paraclinical, genetic (interleukin 6 [IL-6]: IL-6 -174G>C and IL-6 -572C>G gene polymorphisms), and BIA parameters. We noticed that fat mass (FM), muscle mass (MM), bone mass (BM), total body water (TBW), basal metabolism rate (BMR) and metabolic age (P mothers with high GWG. BW was positively correlated with mothers’ FM (P G polymorphism was higher in the control group (P = 0.042). We observed that high GWG may be an important predictor factor for the afterward BW, being positively correlated with FM, TBW, BMR, metabolic age of the mothers, and negatively with the mother's smoking status. Variant genotype (GG+GC) of the IL-6 -572C>G gene polymorphism is a protector factor against obesity in mothers. All the variables considered explained 14.50% of the outcome variance. PMID:27399105

    Full Text Available Introduction: The prevalence of Low Birth Weight (LBW is higher in Asia than elsewhere predominantly because of undernutrition and poor socioeconomic status of mothers. Nearly half of the pregnant women still suffer from varying degrees of anaemia with the highest prevalence in India. Optimal weight gain during pregnancy and a desirable foetal outcome in terms of normal birth weight of the baby may be a result of synergistic effect of literacy, knowledge, improved food intake, and higher level of socioeconomic status of the pregnant women and their family. Aim: To observe the influence of maternal nutritional, socioeconomic status and literacy level on birth weight of babies. Materials and Methods: Total 250 mothers who delivered babies and admitted to the post natal ward of B.S.T. Rural Hospital, Talegaon Dabhade, District Pune, Maharashtra, India, were randomly selected and the relevant information was recorded in self prepared and pre validated questionnaire. Dietary history was collected by 24 hours recall method. Results: A total of 250 mothers and their babies were included. The average birth weight of babies was 2.65 Kg with the lowest birth weight of 1.2 Kg while the highest birth weight of 4 Kg. The prevalence of LBW babies was 27.6%. Most of the women (77.2% had caloric intake less than 1800 Kcal, 80% of mothers had protein intake of less than 45 gm. Nearly, 31.60% of women who were taking daily intake of calories less than 1800 Kcal delivered LBW babies. About 30.50% of the women with protein intake less than 45 gm/ day delivered LBW babies. In all 34.86% of the women with hemoglobin level below 11 gm% delivered LBW babies. These findings were statistically significant. Conclusion: Maternal caloric and protein deficiencies including anaemia during pregnancy had direct effect on the birth weight of newborns, as less nourished mothers were found to deliver higher percentage of LBW babies as compared to the mothers who were better

    Birth weight is an indicator of newborn health and a strong predictor of health outcomes in later life. Significant variation in diet during pregnancy between ethnic groups in high-income countries provides an ideal opportunity to investigate the influence of maternal diet on birth weight. Four multiethnic birth cohorts based in Canada (the NutriGen Alliance). 3997 full-term mother-infant pairs of diverse ethnic groups who had principal component analysis-derived diet pattern scores-plant-based, Western and health-conscious-and birth weight data. No associations were identified between the Western and health-conscious diet patterns and birth weight; however, the plant-based dietary pattern was inversely associated with birth weight (β=-67.6 g per 1-unit increase; P<0.001), and an interaction with non-white ethnicity and birth weight was observed. Ethnically stratified analyses demonstrated that among white Europeans, maternal consumption of a plant-based diet associated with lower birth weight (β=-65.9 g per 1-unit increase; P<0.001), increased risk of small-for-gestational age (SGA; OR=1.46; 95% CI 1.08 to 1.54;P=0.005) and reduced risk of large-for-gestational age (LGA; OR=0.71; 95% CI 0.53 to 0.95;P=0.02). Among South Asians, maternal consumption of a plant-based diet associated with a higher birth weight (β=+40.5 g per 1-unit increase; P=0.01), partially explained by cooked vegetable consumption. Maternal consumption of a plant-based diet during pregnancy is associated with birth weight. Among white Europeans, a plant-based diet is associated with lower birth weight, reduced odds of an infant born LGA and increased odds of SGA, whereas among South Asians living in Canada, a plant-based diet is associated with increased birth weight. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    I examined time trends in low birth weight (LBW) and very low birth weight (VLBW) among interracial compared with single-race infants. Using natality data from 1978 through 1997 for singleton births to black and white parents, I calculated relative risks (RRs) of LBW and VLBW for interracial compared with single-race births, stratified by maternal race and adjusted for maternal characteristics. Among black mothers, interracial births had lower risks of LBW and VLBW than single-race births, and RRs were similar throughout the time period [for example, adjusted RR = 0.76 and 95% confidence interval (CI) = 0.73-0.80 for LBW in 1994-1997]. Among white mothers, interracial infants had higher risks of LBW than single-race infants; however, the adjusted RRs declined over the time period, from 1.22 (95% CI = 1.19-1.27) in 1978-1981 to 1.05 (95% CI = 1.03-1.08) in 1994-1997. Since 1978, there has been some relative improvement in birth outcomes for infants of white mothers and black fathers compared with single-race white births. There was, however, no relative improvement for black mother/black father infants relative to black mother/white father births.

    It is well documented that maternal exposure to second-hand smoke (SHS) during pregnancy causes low birth weight (LBW), but its mechanism remains unknown. This study explored the potential pathways. We enrolled 195 pregnant women who delivered full-term LBW newborns, and 195 who delivered full-term normal birth weight newborns as the controls. After controlling for maternal age, education level, family income, pre-pregnant body mass index, newborn gender and gestational age, logistic regression analysis revealed that LBW was significantly and positively associated with maternal exposure to SHS during pregnancy, lower placental weight, TNF-α and IL-1β, and that SHS exposure was significantly associated with lower placental weight, TNF-α and IL-1β. Structural equation modelling identified two plausible pathways by which maternal exposure to SHS during pregnancy might cause LBW. First, SHS exposure induced the elevation of TNF-α, which might directly increase the risk of LBW by transmission across the placenta. Second, SHS exposure first increased maternal secretion of IL-1β and TNF-α, which then triggered the secretion of VCAM-1; both TNF-α and VCAM-1 were significantly associated with lower placental weight, thus increasing the risk of LBW. In conclusion, maternal exposure to SHS during pregnancy may lead to LBW through the potential pathways of maternal inflammation and lower placental weight.

    To evaluate the association between maternal physical activity and infant's birth weight or risk of inappropriate weight for gestational age (GA), and whether this association differs by infant's sex, maternal body mass index (BMI) or pregnancy complications in a prospective cohort study. 1913 pregnant women from the 3D Birth Cohort (Québec, Canada) completed the Pregnancy Physical Activity Questionnaire at each trimester. Energy expenditure (metabolic equivalent of task (MET)*hours/week) for total activity, sports and exercise and vigorous intensity activities was calculated. The associations with birth weight and risk of inappropriate weight for GA were evaluated by regression modelling. Interactions were tested with infant's sex, maternal prepregnancy BMI, gestational diabetes, hypertensive disorders and prematurity. Each 1 MET/hours/week increase in sports and exercise in the first trimester was associated with a 2.5 g reduction in infant's birth weight (95% CI -4.8 to -0.3) but was not associated with the risk of small weight for GA. In contrast, although not significant, a 17% reduction in the risk of large weight for GA was observed with increasing sports and exercise. Furthermore, in women with subsequent pre-eclampsia (but not normotensive or hypertensive women), each 1 MET/hours/week increment spent in any vigorous exercise in the first trimester reduced the infant's birth weight by 19.8 g (95% CI -35.2 to -4.3). Pregnant women with higher sports and exercise levels in the first trimester delivered infants with a lower birth weight. The risk of reducing infant's birth weight with vigorous exercise in women who develop pre-eclampsia later in pregnancy requires evaluation.

    Lifestyle behaviors such as cigarette smoking, weight gain during pregnancy, and use of other drugs play an important role in determining fetal growth. The relationship between lifestyle risk factors and low birth weight is complex and is affected by psychosocial, economic, and biological factors. Cigarette smoking is the largest known risk factor for low birth weight. Approximately 20% of all low birth weight could be avoided if women did not smoke during pregnancy. Reducing heavy use of alcohol and other drugs during pregnancy could also reduce the rate of low birth weight births. Pregnancy and the prospect of pregnancy provide an important window of opportunity to improve women's health and the health of children. The adoption before or during pregnancy of more healthful lifestyle behaviors, such as ceasing to smoke, eating an adequate diet and gaining enough weight during pregnancy, and ceasing heavy drug use, can positively affect the long-term health of women and the health of their infants. Detrimental lifestyles can be modified, but successful modification will require large-scale societal changes. In the United States, these societal changes should include a focus on preventive health, family-centered workplace policies, and changes in social norms.

    Full Text Available Background and Objectives: Folic acid is a B vitamin which 5mg daily intake before gestation and until the tenth week of pregnancy is recommended. Since no study has been conducted in some regions of East Azerbaijan including Bostanabad, Khosroshahr and Sarab and no prevalence was spotted in country specific studies, therefore, the aim of this study was to determine the relationship between folic acid intake and infant birth weight. Material and Methods: This study was a retrospective cohort. In this study, 1939 of pregnant women who were referred to health care centers before pregnancy were selected randomly. They were divided into two groups: first group of pregnant women who regularly took folic acid before pregnancy and second group included the women who did not take folic acid supplements. Data were analyzed by SPSS 16 using T-Test and ANOVA. Results: This study was conducted on 1939 mothers who had an average age of 25.98 years and average infants birth weight was 3.209 kg. Totally, 92.9% of the mothers had regular consumption of folic acid during pregnancy. Analysis of the results showed that with increasing maternal BMI, birth weight also increased. It showed a significant relationship between regular folic acid intake and increase in infant birth weight. Conclusion : Our results showed that both high maternal pre-pregnancy weight and folic acid intake lead to higher birth weight infants.

    Introduction: Gestational weight gain is an important modifiable factor known to influence fetal outcomes including birth weight and adiposity. Leptin is normally correlated with adiposity and is also known to increase throughout pregnancy, as the placenta becomes a source of leptin synthesis. Several studies have reported positive correlations between cord blood leptin level and either birthweight or size for gestational age, as well as body mass index (BMI).

    Objective Very low birth weight (VLBW) infants are at high risk for morbidity and mortality. This article determines the frequency of disease, rate od survival, complications and risk factors for morbidity and mortality in VLBW neonates admitted to a level III neonatal intensive care unit (NICU) at Mahdieh Hospital in Tehran. Methods This cross-sectional retrospective study was performed from April 2007 to March 2010 on all hospitalized VLBW neonates. Relevant pre- and peri-natal data up to the time of discharge from the hospital or death, including complications during the course of hospitalization, were collected from the case notes, documented on a pre-designed questionnaire and analyzed. Findings Out of 13197 neonates, 564 (4.3%) were VLBW with 51.4% males. Mean gestational age was 29.6±2.5 weeks; mean birth weight 1179±257 grams. Mean birth weight, gestational age and Apgar scores were significantly higher in babies who survived than in those who died, (1275±189 vs. 944±253 grams; 30.5±2.2 vs. 27.5±2 weeks and 6.9±1.7 vs. 5±2.1 respectively, P<0.001 in all instances). Overall survival was 70.9%; in extremely low birth weight (ELBW) newborns this figure was 33.3% rising to 84.1% in infants weighing between 1001-1500 grams. Respiratory failure resulting from RDS in ELBW babies was the major factor leading to death. Need for mechanical ventilation, pulmonary hemorrhage and gastro-intestinal bleeding were also significant predictive factors for mortality. Conclusion Birth weight and mechanical ventilation are the major factors predicting VLBW survival. PMID:24800021

    Full Text Available Epidemiologic evidence provides some support for a causal association between maternal secondhand smoke (SHS exposure during pregnancy and reduction in infant birth weight. The purpose of this cross-sectional study is to examine the magnitude of this association in China, where both prevalence and dose of SHS exposure are thought to be higher than in U.S. populations. Women who gave birth in Beijing and Changchun September 2000–November 2001 were interviewed to quantify self-reported prenatal SHS exposure. Their medical records were reviewed for data on pregnancy complications and birth outcomes. Non-smoking women who delivered term babies (≥37 weeks gestation were included in the study (N = 2,770. Nearly a quarter of the women (24% reported daily SHS exposure, 47% reported no prenatal exposure, and 75% denied any SHS exposure from the husband smoking at home. Overall, no deficit in mean birth weight was observed with exposure from all sources of SHS combined (+11 grams, 95% CI: +2, +21. Infants had higher mean birth weights among the exposed than the unexposed for all measures of SHS exposure. Future studies on SHS exposure and infant birth weight in China should emphasize more objective measures of exposure to quantify and account for any exposure misclassification.

  19. Vacuum assisted birth and risk for cerebral complications in term newborn infants: a population-based cohort study

    Science.gov (United States)

    2014-01-01

    Background Few studies have focused on cerebral complications among newborn infants delivered by vacuum extraction (VE). The aim of this study was to determine the risk for intracranial haemorrhage and/or cerebral dysfunction in newborn infants delivered by VE and to compare this risk with that after cesarean section in labour (CS) and spontaneous vaginal delivery, respectively. Methods Data was obtained from Swedish national registers. In a population-based cohort from 1999 to 2010 including all singleton newborn infants delivered at term after onset of labour by VE (n = 87,150), CS (75,216) or spontaneous vaginal delivery (n = 851,347), we compared the odds for neonatal intracranial haemorrhage, traumatic or non-traumatic, convulsions or encephalopathy. Logistic regressions were used to calculate adjusted (for major risk factors and indication) odds ratios (AOR), using spontaneous vaginal delivery as reference group. Results The rates of traumatic and non-traumatic intracranial hemorrhages were 0.8/10,000 and 3.8/1,000. VE deliveries provided 58% and 31.5% of the traumatic and non-traumatic cases, giving a ten-fold risk [AOR 10.05 (4.67-21.65)] and double risk [AOR 2.23 (1.57-3.16)], respectively. High birth weight and short mother were associated with the highest risks. Infants delivered by CS had no increased risk for intracranial hemorrhages. The risks for convulsions or encephalopathy were similar among infants delivered by VE and CS, exceeding the OR after non-assisted spontaneous vaginal delivery by two-to-three times. Conclusion Vacuum assisted delivery is associated with increased risk for neonatal intracranial hemorrhages. Although causality could not be established in this observational study, it is important to be aware of the increased risk of intracranial hemorrhages in VE deliveries, particularly in short women and large infants. The results warrant further studies in decision making and conduct of assisted vaginal delivery. PMID:24444326

    The health and survival of women and their new-born babies in low income countries has been a key priority in public health since the 1990s. However, basic planning data, such as numbers of pregnancies and births, remain difficult to obtain and information is also lacking on geographic access to key services, such as facilities with skilled health workers. For maternal and newborn health and survival, planning for safer births and healthier newborns could be improved by more accurate estimations of the distributions of women of childbearing age. Moreover, subnational estimates of projected future numbers of pregnancies are needed for more effective strategies on human resources and infrastructure, while there is a need to link information on pregnancies to better information on health facilities in districts and regions so that coverage of services can be assessed. This paper outlines demographic mapping methods based on freely available data for the production of high resolution datasets depicting estimates of numbers of people, women of childbearing age, live births and pregnancies, and distribution of comprehensive EmONC facilities in four large high burden countries: Afghanistan, Bangladesh, Ethiopia and Tanzania. Satellite derived maps of settlements and land cover were constructed and used to redistribute areal census counts to produce detailed maps of the distributions of women of childbearing age. Household survey data, UN statistics and other sources on growth rates, age specific fertility rates, live births, stillbirths and abortions were then integrated to convert the population distribution datasets to gridded estimates of births and pregnancies. These estimates, which can be produced for current, past or future years based on standard demographic projections, can provide the basis for strategic intelligence, planning services, and provide denominators for subnational indicators to track progress. The datasets produced are part of national midwifery

    Gestational weight gain is a determinant of infant birth weight, but it is unclear whether its timing in pregnancy may hold implications in this regard. Previous studies have yielded conflicting findings on the association of maternal weight gain in early pregnancy with birth weight. However, as these studies have typically recruited women during the first trimester, they are inherently limited by a reliance on self-reported pregravid weight. To evaluate the associations of directly measured maternal pregravid weight and the timing of subsequent weight gain across pregnancy with infant birth weight. In this prospective, preconception, observational cohort study, 1164 newly married women in Liuyang, China, underwent pregravid evaluation at a median of 19.9 weeks before a singleton pregnancy during which they underwent serial weight measurements. The study was conducted from February 1, 2009, to November 4, 2015. Data analysis was performed between September 1, 2016, and May 6, 2017. Maternal weight gain was calculated for the following 10 gestational intervals: from pregravid to less than 14, 14 to 18, 19 to 23, 24 to 28, 29 to 30, 31 to 32, 33 to 34, 35 to 36, 37 to 38, and 39 to 40 weeks. Associations of pregravid weight and weight gain within each of the 10 gestational intervals with the outcome of infant birth weight. The mean (SD) age of the 1164 women included in the study was 25.3 (3.1) years. Pregravid weight was consistently associated with infant birth weight. However, among the 10 gestational intervals, only weight gain from pregravid to 14 weeks and from 14 to 18 weeks was associated with birth weight. Birth weight increased by 13.6 g/kg (95% CI, 3.2-24.1 g/kg) of maternal weight gain from pregravid to 14 weeks and by 26.1 g/kg (95% CI, 3.8-48.4 g/kg) of maternal weight gain from 14 to 18 weeks. Maternal weight only in the first half of gestation is a determinant of infant birth weight. Before pregnancy and early gestation may be a critical window for

    Stable circadian rhythm is important for both maternal and fetal health. This retrospective analysis of women in a semiconductor factory evaluated the effect of shift work exposure on childbearing and birth weight. Records of 440 female employees (initial mean age: 28.4 years) including 111 mothers who had 158 live births during the period of observation (1997-2007) were reviewed. The data analyzed included maternal age, general health condition, highest educational level, life-style and occupational factors, as well as newborn gender, birth weight, birth order and gestational age. The childbearing rates of female workers on three different work schedules (consistent daytime work (CDW), intermittent (i-) or persistent (p-) rotating shift works (RSW)) were 32.1%, 20.0% and 25.4%, respectively (P=0.047). After controlling for potential confounding factors, childbearing rates among women with CDW exceeded those of shift workers (odds ratio (OR), 1.7; 95% confidence interval (CI), 1.0-3.0). The birth weights of newborns from mothers on the three work schedules (CDW, i-RSW and p-RSW) were significantly different (3271.7±395.4, 3251.3±460.9, and 2998.5±381.2 g, respectively (Pmanufacturing factory. Work schedules should be carefully planned for female employees who are pregnant or preparing for pregnancy. Prenatal evaluations for mothers with persistent day-night rotating shift work exposures are especially necessary.

    Women who drink light-to-moderately during pregnancy have been observed to have lower risk of unfavourable pregnancy outcomes than abstainers. This has been suggested to be a result of bias. In a pooled sample, including 193 747 live-born singletons from nine European cohorts, we examined...... alcohol. This decreased to 39% in 2000–2004, and 14% in 2005–2011.

    Full Text Available Abstract Background Intake of colostrum after birth is essential to stimulate intestinal growth and function, and to provide systemic immunological protection via absorption of Immunoglobulin G (IgG. The birth order and weight of 745 piglets (from 75 litters were recorded during a one-week period of farrowing. Only pigs weighing greater than 0.68 kg birth weight were chosen for the trial. Sow colostrum was collected during parturition, and piglets were bled between 48 and 72 hours post-birth. Piglet serum IgG and colostral IgG concentrations were determined by radial immunodiffusion. Results Sow parity had a significant (P Conclusion We found that the combination of sow colostrum IgG concentration and birth order can account for 10% of the variation of piglet serum IgG concentration and that piglets with less than 1,000 mg/dl IgG serum concentration and weight of 0.9 kg at birth had low survival rate when compared to their larger siblings. The effective management of colostrum uptake in neonatal piglets in the first 24 hrs post-birth may potentially improve survival from birth to weaning.

    Prevalence of low birth weight deliveries may vary across different environments. The necessity of determination of regional data prompted this study. Information of all deliveries from January 2004 to December 2008 was obtained from delivery registry records retrospectively. Initial data including birth weight, vital status, sex, maternal age and mode of delivery were recorded using medical files. The frequency of low birth weight, very low birth weight, extremely low birth weight and stillbirth deliveries were determined. Among 19,533 total births, there were 450 (23.04 per 1000) stillbirths. Low birth weight rate was 10.61%. A significant increase in yearly distribution of low birth weight deliveries was observed (Pbirth weight and extremely low birth weight delivery rates were 3.14% and 1.58% respectively. Among 2073 low birth weight infants, 333 (16.06%) were stillbirths. The stillbirth delivery rate and the birth of a female infant among low birth weight deliveries were significantly higher than infants with birth weight ≥2500g (Pbirth weight and maternal age. The rate of cesarean section among low birth weight infants was 49.4%. High low birth weight and stillbirth rates, as well as the increase in low birth weight deliveries over the past five years in this study are striking. For reduction of increased low birth weight rates, appropriate intervention methods should be initiated.

    Construct updated birth weight-for-gestational age centile charts for use in the UK and compare these to the currently used UK-WHO charts. Secondary analysis of national birth data. Centiles were constructed using 1 269 403 singleton births occurring in England and Wales in 2013-2014 as part of the MBRRACE-UK national perinatal surveillance programme. These were then validated using 642 737 singleton births occurring in England and Wales in 2015. Sex-specific birth weight-for-gestational age centiles. Centiles were created using the lambda-mu-sigma method via the GAMLSS package in R. This method transforms the skewed birth weight distribution to approximate a normal distribution, allowing any birth weight centile to be produced. The new centiles performed well in the validation sample, with the observed and expected proportion of births below a given centile in agreement. Overall, driven by the predominance of term births, the UK-WHO charts classify a smaller proportion of infants as below a given centile. For example, the UK-WHO estimates classified only 1.32% (8035/606 430) of term infants born in 2015 as below the second centile, compared with 1.97% (11 975/606 430) using the new MBRRACE-UK centiles. At the earliest gestational ages, however, the opposite is observed, with the UK-WHO classifying a larger proportion of infants as below a given centile, particularly at the lower end of the birthweight distribution. We have constructed and validated updated birth weight-for-gestational age centiles using a contemporary sample of births occurring in England and Wales. The benefits of these updated centiles will be first to assist the national surveillance of perinatal mortality programme by improving the identification of the proportion of stillbirths and neonatal deaths affected by intrauterine growth restriction and, second, to aid clinicians by more accurately identifying babies who require increased monitoring in the period immediately following birth.

    Efforts to formalise the role of traditional birth attendants (TBAs) in maternal and neonatal health programmes have had limited success. TBAs' continued attendance at home deliveries suggests the potential to influence maternal and neonatal outcomes. The objective of this qualitative study was to identify and understand the knowledge, attitudes and practices of TBAs in rural Nepal. Twenty-one trained and untrained TBAs participated in focus groups and in-depth interviews about antenatal care, delivery practices, maternal complications and newborn care. Antenatal care included advice about nutrition and tetanus toxoid (TT) immunisation, but did not include planning ahead for transport in cases of complications. Clean delivery practices were observed by most TBAs, though hand-washing practices differed by training status. There was no standard practice to identify maternal complications, such as excessive bleeding, prolonged labour, or retained placenta, and most referred outside in the event of such complications. Newborn care practices included breastfeeding with supplemental feeds, thermal care after bathing, and mustard seed oil massage. TBAs reported high job satisfaction and desire to improve their skills. Despite uncertainty regarding the role of TBAs to manage maternal complications, TBAs may be strategically placed to make potential contributions to newborn survival.

    Full Text Available Hypertension is an increasing health issue in sub-Saharan Africa where malaria remains common in pregnancy. We established a birth cohort in Nigeria to evaluate the early impact of maternal malaria on newborn blood pressure (BP.Anthropometric measurements, BP, blood films for malaria parasites and haematocrit were obtained in 436 mother-baby pairs. Women were grouped to distinguish between the timing of malaria parasitaemia as 'No Malaria', 'Malaria during pregnancy only' or 'Malaria at delivery', and parasite density as low (<1000 parasites/µl of blood and high (≥ 1000/µl.Prevalence of maternal malaria parasitaemia was 48%, associated with younger maternal age (p<0.001, being primigravid (p = 0.022, lower haematocrit (p = 0.028. High parasite density through pregnancy had the largest effect on mean birth indices so that weight, length, head and mid-upper arm circumferences were smaller by 300 g, 1.1 cm, 0.7 cm and 0.4 cm respectively compared with 'No malaria' (all p ≤ 0.005. In babies of mothers who had 'malaria at delivery', their SBPs adjusted for other confounders were lower respectively by 4.3 and 5.7 mmHg/kg compared with 'malaria during pregnancy only' or 'none'. In contrast the mean newborn systolic (SBP and diastolic BPs (DBP adjusted for birth weight were higher by 1.7 and 1.4 mmHg/kg respectively in babies whose mothers had high compared with low parasitaemia.As expected, prenatal malarial exposure had a significant impact on fetal growth rates. Malaria at delivery was associated with the lowest newborn BPs while malaria through pregnancy, which may attenuate growth of the vascular network, generated higher newborn BPs adjusted for size. These neonatal findings have potential implications for cardiovascular health in sub-Saharan Africa.

    Full Text Available INTRODUCTION. The incidence of multiple births has increased in the last decade. Perinatal mortality in triplets is significantly greater than in twin and singleton births. OBJECTIVE. The objective of this study was to describe the extent of birth weight discordance among triplets and to identify its association with an increased risk of perinatal mortality. METHOD A retrospective analysis of triplet births, for the period 1993-2003, was conducted at the Gynaecological-Obstetric Clinic "Narodni Front" in Belgrade. Birth weight discordance was defined as the difference in birth weight between the largest and the smallest triplet's weight of more than 20%. RESULTS. The rate of triplets has increased by almost 75% between the first (7.7% and the last (29.6% 5-year period of the last decade. Triplets are becoming more common because of the frequent use of assisted reproductive technology as a treatment for infertility. In the period 1993-2003, there were a total of 40 triplet live births (24 weeks and greater with incidence of 0.06%. There was no clear association between maternal age, parity, method of conception, birth gestational age, and disorders complicating pregnancy with birth discordance more than 20%. Regarding birth weight groups, statistical significance occurred only in the <999 grams group for discordant and in the 2000-2499 grams group for concordant triplets. Overall, the perinatal mortality rate in the group was 10.8%, the foetal mortality rate was 1.7% (2/120, and the neonatal (0-28 days mortality rate was 9.1% (11/120. An odds ratio of 95% confidence interval shows 3 times greater risk for adverse perinatal outcome in the discordant group. However, the difference was not significant. CONCLUSION. Increasing birth weight discordance may increase the risk of adverse perinatal outcome. Triplet pregnancies, being high risk, require intensive antenatal care in order to prevent preterm delivery and ultrasound in order to diagnose foetal

    Full Text Available Background and Objectives: Low birth weight (LBW is a major public health problem. LBW is associated with increased neonatal morbidity and mortality. There is no consensus in the literature as to whether maternal copper nutrition is associated with pregnancy outcome or fetal growth. Methods: This case-control study was carried out at Alavi Hospital in Ardabil between August 2008 and August 2009. 56 women who had delivered low-birth- weight infants (<2500gr were taken as the case group, and from the mothers who had delivered normal birth weight infants (≥2500gr, 56 were selected at random as the control group. Venous blood samples were obtained from the mothers. Serum zinc level was determined by the Atomic Absorption Spectrophotometer method.Results: Mean of birth weight in infants, maternal age, body mass index in mothers and socioeconomic or demographic factors did not differ between cases and control groups. Maternal copper concentration (μg/dl differed between Cases and Controls; 231.75±38.12μg/dl vs. 204.42±31.30μg/dl respectively. There is a significant difference (p<0.001 in the serum copper concentration between the two groups.Conclusion: There is a negative relation between low infant birth weight and maternal copper concentration.

    Individuals born at low or high birth weight (BW) have elevated adiposity. The extent to which physical activity can mitigate this risk is unknown. The aim of this study was to determine if associations between BW and adiposity vary by self-reported moderate-to-vigorous physical activity (MVPA) among adolescents. We used data on adolescents in the National Health and Nutrition Examination Survey (1999-2006; 12-15 years; n = 4064). Using gender-stratified linear regression, we modelled body mass index (BMI) and waist circumference (WC) z-scores as a function of low, normal and high BW, MVPA (weekly Metabolic Equivalent of Task hours) and MVPA*BW cross-product terms, adjusting for sociodemographics, diet and, in WC models, BMI. Among girls with low MVPA, those born with high BW had greater BMI than normal BW; this difference diminished with greater MVPA (coefficient [95% confidence interval]: low MVPA: 0.72 [0.29, 1.14]; high MVPA: -0.04 [-0.48, 0.39]; P for interaction = 0.05). Among boys, MVPA did not modify the associations between BW and BMI. WC was unrelated to BW, regardless of MVPA. Findings suggest that effects of high BW in total adiposity can be more easily modified with MVPA in adolescent girls than in boys. © 2015 World Obesity.

    Urinary tract infection (UTI) is the most common disorder caused by bacterial agents in pregnancy, which can lead to important complications in newborn of such mothers in case of inappropriate diagnosis and treatment. The purpose of this study was to study the prevalence of UTI among pregnant women and its complications in their newborns during the birth in the hospitals of Dezful City, Iran, during 2012 - 2013. In this cross-sectional retrospective study, 1132 women admitted to Dr. Ganjavian and Ayatollah Nabavi Hospitals in Dezful City, Iran, during 2012 - 2013 were randomly allocated into the case and control groups and were matched based on their age, numbers of pregnancy, sex and diseases of their children. UTI was the only difference between the two groups. Twenty-two thousand six hundred deliveries occurred within the course of this study. Due to UTI, 5% of deliveries led to hospitalization of mothers (1132 patients).Weight and height of newborn infants of mothers afflicted with UTI (P UTI in terms of type of delivery (normal and caesarean section) (P UTI in pregnant women compared to other areas of Iran represents the role of climate and weather in the prevalence of UTI. In addition, the increased number of low-birth-weight infants had a remarkable correlation with UTI, which can influence the health of the next generation.

    Full Text Available ABSTRACT: Low birth weight (LBW is public health problem, because they are associated with increased risk of morbidity and mortality. No previous studies on factors associated with LBW carried out in central Brazil were found in the literature. The main aims of this study were to determine the prevalence and the factors associated with LBW in children born alive in the State of Goiás, Brazil. A cross-sectional analysis was performed using data from the Live Births Information System from the Brazilian Health Ministry. All 92.745 singleton births in the State of Goiás during the year of 2000 were examined. Logistic regression analysis was used to examine the factors associated with LBW (< 2500 g. In Goiás, the prevalence of LBW was 5.96% and the most important factors associated with LBW were: prematurity, young and older mothers, unmarried women, mother illiteracy, mothers who had less than seven prenatal care visits, non-hospital delivery, and female infants. Local public health actions are necessary to reduce inequalities in infant and maternal care. KEYWORDS: newborn, birth weight, prenatal care.

    We have read with interest the article by Lu et al. entitled "Association of excessive mobile phone use during pregnancy with birth weight: an adjunct study in Kumamoto of Japan Environment and Children's Study" published recently in the Environmental Health and Preventive Medicine. Although this paper addresses a very challenging issue, it has some shortcomings. Mortazavi et al. have previously studied the effects of ionizing and non-ionizing radiation on birth weight of newborns and found no statistical significant differences between the mean weight of newborns whose mothers had been exposed to electromagnetic fields (EMF) generated by mobile phones and those of non-exposed mothers. The study performed by Lu et al. cannot answer this very key question that whether ordinary use of mobile phone during pregnancy can lead to low birth weight. The origin of the controversy between the findings of these two studies and the shortcomings of the article by Lu et al. are discussed.

    Full Text Available Objective: The purpose of this study is to describe the neurodevelopmental sequelae in premature newborns with extremely low weight and with very low weight at two years of age who left the Neonatal Intensive Care Unit of the Hospital Nacional Edgardo Rebagliati Martins. Materials and methods: A descriptive, retrospective, cross-sectional study in a population of 190 premature newborns with extremely low weight and with very low weight born from January 2009 to June 2014 who left the Neonatal Intensive Care Unit and took part in the follow-up program. The psychomotor development, sensorineural hearing loss, retinopathy of prematurity, presence of cerebral palsy and convulsive syndrome were assessed. Results: The average weight at birth was 1,180.53 ± 212.40 grams with a gestational age of 29.86 ± 2.33 weeks, and 51.58% of the newborns were male. Forty-two point six three percent (42.63% of the premature newborns with very low weight showed retardation of psychomotor development; 25.26%, retinopathy; 13.68%, sensorineural hearing loss; 3.68%, cerebral palsy; and 3.68%, convulsive syndrome. Fifty-two point two seven percent (52.27% of the premature newborns with extremely low weight showed retardation of psychomotor development; 50%, retinopathy; 15.91%, sensorineural hearing loss; and 2.27%, convulsive syndrome. Conclusions: Retardation of psychomotor development and retinopathy were the most important complications shown by premature newborns with extremely low weight and with very low weight at two years of age.

    Recent findings suggest that there may be a maternal immune response underpinning the etiology of sexual orientation of gay male only-children. This maternal immune response appears to be distinct from that which is purported to explain the classic fraternal birth order effect found in studies of male sexual orientation. We tested two predictions related to the hypothesized maternal immune response in mothers of gay male only-children: (1) elevated fetal loss among mothers who have had gay male only-children and (2) lower birth weight in gay male only-children. Mothers of at least one gay son (n = 54) and mothers of heterosexual son(s) (n = 72) self-reported their pregnancy histories, including the birth weights of newborns and number of fetal losses (e.g., miscarriages). Mothers of gay male only-children (n = 8) reported significantly greater fetal loss compared with mothers of males with four other sibship compositions (gay with no older brothers, gay with older brothers, heterosexual only-children, heterosexual with siblings) (n = 118). Also, firstborn gay male only-children (n = 4) had a significantly lower birth weight than firstborn children in the four other sibship compositions (n = 59). Duration of pregnancy was not significantly different among the groups of firstborn children in the birth weight analyses. Thus, this study found further support for a distinct pattern of maternal immune response implicated in the etiology of male sexual orientation. Mechanisms that may underlie this potential second type of maternal immune response are discussed.

    Full Text Available Weight at birth is usually considered as an indicator of the health status of a given society. As a result this study was designed to investigate the association between birth weight and maternal factors such as gestational weight gain, pre-pregnancy BMI and socio-economic status in Northern Ghana.The study was a facility-based cross-sectional survey conducted in two districts in the Northern region of Ghana. These districts were purposively sampled to represent a mix of urban, peri-urban and rural population. The current study included 419 mother-infant pairs who delivered at term (37-42 weeks. Mother's height, pre-pregnancy weight and weight changes were generated from the antenatal records. Questionnaires were administered to establish socio-economic and demographic information of respondents. Maternal factors associated with birth weight were examined using multiple and univariate regressions.The mothers were generally well nourished before conception (Underweight 3.82%, Normal 57.76%, Overweight 25.06% and Obesity 13.37% but approximately half of them could not gain adequate weight according to Institute of Medicine recommendations (Low weight gain 49.64%, Adequate weight gain 42.96% and Excessive weight gain 7.40%. Infants whose mothers had excess weight gain were 431g (95% CI 18-444 heavier compared to those whose mothers gained normal weight, while those whose mothers gained less were 479g (95% CI -682- (-276 lighter. Infants of mothers who were overweight and obese before conception were 246g (95% CI 87-405 and 595g (95% CI 375-815 respectively heavier than those of normal mothers, whereas those whose mothers were underweight were 305g (95% CI -565 -(-44 lighter. The mean birth weight observed was 2.98 ± 0.68 kg.Our findings show that pre-pregnancy body mass index and weight gain during pregnancy influence birth weight. Therefore, emphasis should be placed on counseling and assisting pregnant women to stay within the recommended weight

    Objective: To determine the association of socio-demographic, maternal, medical and obstetric risk factors with low birth weight. Results: The mean weight of cases was 2.08 kg as compared to 3.1 in controls. Forty-sixty percent of cases were preterm. The factors like maternal malnutrition, young age of the mothers, poverty, close birth spacing, hypertension and antenatal per vagamin (p/v) bleeding during pregnancy have independent effect in causing low birth weight (LBW). Conclusion: Maternal bio social, medical and obstetric factors have strong association with LBW. To overcome this problem, special attention is required to strengthen the mother and child health care services in the community. (author)

    Time diaries of sibling pairs from the PSID-CDS are used to determine whether maternal time investments compensate for or reinforce birth-weight differences among children. The findings demonstrate that the direction and degree of differential treatment vary by mother's education. Less-educated mothers devote more total time and more educationally oriented time to heavier-birth-weight children, whereas better-educated mothers devote more total and more educationally oriented time to lower-birth-weight children. The compensating effects observed among highly educated mothers are substantially larger than the reinforcing effects among the least-educated mothers. The findings show that families redistribute resources in ways that both compensate for and exacerbate early-life disadvantages. PMID:22865101

    Despite improvements in service delivery and patient management, low birth weight among infants has been a persistent challenge in South Africa. The study aimed to explore the relationship between depression before pregnancy and the low birth weight (LBW) of infants in post-apartheid South Africa. This study utilized data from Waves 1 and 2 of the South African National Income Dynamics Study, the main outcome being a dichotomous measure of child LBW (<2500 g) drawn from the Wave 2 child questionnaire. Depressive symptoms of non-pregnant women was the main predictor drawn from the Wave 1 adult questionnaire. Depressive symptoms were screened using the 10-item four-point Likert version of the Center for Epidemiologic Studies Depression Scale (CES-D) instrument. A total score of 10 or greater on the CES-D indicates a positive screen for depressive symptoms. An adjusted logistic regression model was used to examine the relationship between women's depression before pregnancy and infant LBW. A sample size of 651 women in Wave 1 was linked to 672 newborns in Wave 2. The results of the adjusted logistic regression model indicated depressive symptoms (CES-D ≥ 10) prior to pregnancy were associated with infant LBW (adjusted OR 2.84, 95 % CI 1.08-7.46). Another significant covariate in the model was multiple childbirths. Our finding indicates that women's depressive symptoms prior to pregnancy are associated with the low birth weight of newborns and suggests that this association may not be limited to depression present during the ante-natal phase.

    Full Text Available ABSTRACT             Asphyxia is breathing difficulty that occurs in newborns. Low birth weight (LBW neonates often suffer from asphyxia, this are due to surfactant deficiency, incomplete lung growth, weak respiratory muscles, and easily bent ribs, therefore it can not supply oxygen enough of the placenta. Data from Arifin Achmad Hospital showed that the number of neonatal asphyxia includes 15 largest disease as the cause of infant mortality. In 2014 from January to September there were 36 cases of asphyxia of 955 newborns (3.76%. The purpose of this study was to determine the relationship between LBW and asphyxia neonatorum at Arifin Achmad Hospital Riau Province in 2014. This research method used quantitative analytical research and the design was case control. This research was conducted at Arifin Achmad Hospital Riau Province on March 3 until May 3 2015. The population in this study was all newborn babies who born at Arifin Achmad Hospital and samples were 72 respondents which consisted of 36 cases and 36 control. The sampling technique was simple random sampling. Data collection used secondary data by using a checklist sheet, data was processed by computer and data analysis used univariate and bivariate. The results from the chi square test showed that there was a relationship between LBW and asphyxia indicated by p value = 0.002 <0.05. It is expected that health professionals can provide information about the factors related to asphyxia as low birth weight, risk factor of maternal nutritional status to the mother and fetus. In addition, to health workers are also expected to provide information to pregnant women about how to prevent LBW and asphyxia by providing brochures, leaflets and others.

    Full Text Available CONTEXT AND OBJECTIVE: Accurate fetal weight estimation is important for labor and delivery management. So far, there has not been any conclusive evidence to indicate that any technique for fetal weight estimation is superior to any other. Clinical formulas for fetal weight estimation are easy to use but have not been extensively studied in the literature. This study aimed to evaluate the accuracy of clinical formulas for fetal weight estimation compared to maternal and ultrasound estimates. DESIGN AND SETTING: Prospective study involving 100 full-term, cephalic, singleton pregnancies delivered within three days of fetal weight estimation. The setting was a tertiary public teaching hospital in São Paulo, Brazil. METHODS: Upon admission, the mother's opinion about fetal weight was recorded. Symphyseal-fundal height and abdominal girth were measured and two formulas were used to calculate fetal weight. An ultrasound scan was then performed by a specialist to estimate fetal weight. The four estimates were compared with the birth weight. The accuracy of the estimates was assessed by calculating the percentage that was within 10% of actual birth weight for each method. The chi-squared test was used for comparisons and p < 0.05 was considered significant. RESULTS: The birth weight was correctly estimated (± 10% in 59%, 57%, 61%, and 65% of the cases using the mother's estimate, two clinical formulas, and ultrasound estimate, respectively. The accuracy of the four methods did not differ significantly. CONCLUSION: Clinical formulas for fetal weight prediction are as accurate as maternal and ultrasound estimates.

    The objectives of this study are (1) to design an accurate method for linking newborn screening (NBS) and state birth certificate databases to create a de-identified study database; (2) To assess maternal cytomegalovirus (CMV) seroprevalence by measuring CMV IgG in newborn dried blood spots; (3) To assess congenital CMV infection among newborns and possible association with preterm birth. NBS and birth databases were linked and patient records were de-identified. A stratified random sample of records based on gestational age was selected and used to retrieve blood spots from the state NBS laboratory. Serum containing maternal antibodies was eluted from blood spots and tested for the presence of CMV IgG. DNA was extracted from blood spots and tested for the presence of CMV DNA. Analyses were performed with bivariable and multivariable logistic regression models. Linkage rates and specimen collection exceeded 98% of the total possible yielding a final database with 3,101 newborn blood spots. CMV seroprevalence was 91% among Black mothers, 83% among Hispanic mothers, 59% among White mothers, and decreased with increasing amounts of education. The prevalence of CMV infection in newborns was 0.45% and did not vary significantly by gestational age. Successful methods for database linkage, newborn blood spots collection, and de-identification of records can serve as a model for future congenital exposure surveillance projects. Maternal CMV seroprevalence was strongly associated with race/ethnicity and educational level. Congenital CMV infection rates were lower than those reported by other studies and lacked statistical power to examine associations with preterm birth.

    To measure serum levels of heavy metals in Chinese pregnant women and their newborns, and to evaluate the association of these metals with infant birth weight. We measured serum concentrations of lead (Pb), thallium (Tl), cadmium (Cd), selenium (Se), arsenic (As), nickle (Ni), vanadium (V), cobalt (Co), and mercury (Hg) in 81 mother-infant pairs using an inductively coupled plasma mass spectrometry method. Multiple linear regression analyses were used to evaluate the associations of these heavy metals with infant birth weight. Se, Pb, As, and Cd showed the highest detection rates (98.8%) in both the maternal and cord blood, followed by Tl, which was detected in 79.0% and 71.6% of the maternal and cord blood samples, respectively. Pb had the highest concentrations in both the maternal and cord blood samples of all toxic metals detected, with concentrations of 23.1 ng/g and 22.0 ng/g, respectively. No significant associations were observed between any heavy metals and birth weight. However, Tl in the maternal and cord blood was most notably inversely associated with birth weight. Se intake was low in Chinese women and their newborns, whereas Pb had the highest concentrations in both the maternal and cord blood samples of all toxic metals detected. Tl was a unique pollution source in this population, and Tl levels were shown to have the largest effect on decreasing infant birth weight in this pilot study. Further research incorporating larger sample sizes is needed to investigate the effects of prenatal exposure to heavy metals--especially Tl and Pb--on birth outcome in Chinese infants.

    This study investigated whether newborn body composition is influenced by prepregnancy obesity and gestational weight gain (GWG) and explored any associations between body composition and birthweight standard score (z-score), categorised by size for gestational age. We recruited 231 obese and 80 normal weight mothers and their newborn infants and assessed the babies' body composition using dual-energy X-ray absorptiometry. The total and abdominal fat masses of infants born to mother who were obese before pregnancy were 135 g (p weight mothers. The infants' fat mass increased by 11 g (p gestational age (15.3%) than small for gestational age (5.2%) and appropriate for gestational age (9.8%) (p < 0.001). Lower birthweight z-score was associated with a higher proportion of abdominal fat mass (p = 0.009). Infants born to obese mothers had higher fat mass at birth, with abdominal fat accumulation. Low birthweight was associated with a lower crude abdominal fat mass, but a higher proportion of total fat mass placed abdominally. ©2014 Foundation Acta Paediatrica.

    2015-09-01

    A decade ago, the political party of the Italian center-right voted a law restricting immigration. The law became effective in early 2005, when the Italian parliament approved the decree for its application, but one of its articles, granting amnesty for illegal immigrant workers, became immediately effective in July 2002. As a result, 650,000 immigrants were granted the status of foreign nationals in Italy. In this paper, we examine whether the increase in the prevalence of "regular immigrants" has led to an improvement in health outcomes of babies born to migrant women, measured in terms of birth weight. Two hitherto unexploited birth sample surveys published by Italian Institute of Statistics were used for this study. Our estimates show that regularized immigration reduced the probability of low birth weight. Copyright © 2015 Elsevier B.V. All rights reserved.

    To assess the association between alcohol abuse during gestation and low birth weight. Cross-sectional, population-based nested study from a cohort of 957 pregnant women who received prenatal assistance through Sistema Único de Saúde (National Health System) in the city of Pelotas, Southern Brazil, and delivered their babies between September 2007 and September 2008. The mothers were interviewed at two distinct moments: prenatal and postpartum periods. In order to verify alcohol abuse, the CAGE (Cut down, Annoyed by criticism, Guilty and Eye-opener) scale was used. Bivariate analyses were carried out, as well as multiple logistic regression adjusted by the variables prematurity and alcohol abuse. The level of significance that was adopted was 95%. Of the women who participated in the study, 2.1% abused alcohol during pregnancy and, among these, 26.3% had low birth weight children. There was an association between alcohol abuse and low birth weight (palcohol abuse during pregnancy is associated with low birth weight.

    Full Text Available OBJECTIVE: The aim of this study was to assess the cognitive and behavioral development of preterm and low birth weight newborns living in a disadvantageous socioeconomic environment at school age. METHODS: This cross-sectional study included children aged 6-7 from a historical birth cohort of preterm (gestational age <37 weeks and low birth weight (<2,500 g infants. The Wechsler Intelligence Scale for Children III (WISC-III was administered by a psychologist while the parents completed the Child Behavior Checklist. The results were compared to the test's reference. The perinatal information and follow-up data were collected from the hospital files. The demographic data were collected from the parents. The current performance was compared with the results from the Denver II and Bayley II tests, which were administered during the first years of life. RESULTS: The total intelligence quotient varied from 70 to 140 (mean 98.7±15.8. The borderline intelligence quotient was observed in 9.3% of the children. The Child Behavior Checklist indicated a predominance of social competence problems (27.8%, CI 19.2 to 37.9 compared with behavioral problems (15.5%, CI 8.9 to 24.2. Both the Child Behavior Checklist domains, such as schooling, social and attention problems, and the cognitive scores were significantly associated with maternal education and family income. The results of the Denver and Bayley tests were associated with the cognitive performance (p<0.001 and the Child Behavior Checklist social profile, including aggressive and externalizing behavior (p<0.001. CONCLUSIONS: Our data suggest that even low-risk preterm newborns are at risk for developing disturbances in early school age, such as mild cognitive deficits and behavioral disorders. This risk might increase under unfavorable socioeconomic conditions.

    Full Text Available Abstract Background Healthy infants typically regain their birth weight by 21 days of age; however, failure to do so may be due to medical, nutritional or environmental factors. Globally, the incidence of low birth weight deliveries is high, but few studies have assessed the postnatal weight changes in this category of infants, especially in Africa. The aim was to determine what proportion of LBW infants had not regained their birth weight by 21 days of age after discharge from the Special Care Unit of Mulago hospital, Kampala. Methods A cross sectional study was conducted assessing weight recovery of 235 LBW infants attending the Kangaroo Clinic in the Special Care Unit of Mulago Hospital between January and April 2010. Infants aged 21 days with a documented birth weight and whose mothers gave consent to participate were included in the study. Baseline information was collected on demographic characteristics, history on pregnancy, delivery and postnatal outcome through interviews. Pertinent infant information like gestation age, diagnosis and management was obtained from the medical records and summarized in the case report forms. Results Of the 235 LBW infants, 113 (48.1% had not regained their birth weight by 21 days. Duration of hospitalization for more than 7 days (AOR: 4.2; 95% CI: 2.3 - 7.6; p value Conclusion Failure to regain birth weight among LBW infants by 21 days of age is a common problem in Mulago Hospital occurring in almost half of the neonates attending the Kangaroo clinic. Currently, the burden of morbidity in this group of high-risk infants is undetected and unaddressed in many developing countries. Measures for consideration to improve care of these infants would include; discharge after regaining birth weight and use of total parenteral nutrition. However, due to the pressure of space, keeping the baby and mother is not feasible at the moment hence the need for a strong community system to boost care of the infant. Close

    In malaria-endemic countries, one adverse consequence of placental malaria on infants is low birth weight (LBW) caused by intra-uterine growth retardation and pre-term delivery. The effect of placental malaria on birth weight of babies was investigated in Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, Anambra state, Nigeria. Placental blood was collected from 364 women who gave birth in NAUTH. Thin and thick placental blood smears were made and checked for the presence of malaria parasites. Plasmodium falciparum antigen rapid kit was used to confirm the presence of P. falciparum. New-borns were weighed and classified as normal birth weight (≥2500 g) or LBW (<2500 g). Analysis of variance (ANOVA), Student's t and Pearson chi-square tests were used to compare means and percentages. Risk factors for LBW were also determined. Placental malaria was found in 55.2% (n = 201) of the women. Placental malaria was associated with gravidity while age was not. In all the age groups, primigravidae and secundigravidae were mostly infected. Women with placental malaria delivered more LBW babies (32.1%) than their uninfected counterparts (5.5%), with primigravidae having more LBW babies. Similarly, weight of babies born by infected women was significantly different from that of uninfected women (p <0.0001). In multivariate analysis, placental malaria was associated with LBW (OR 0.1, 95% CI 0.06-0.17, p <0.0001). The result suggests a high prevalence of placental malaria and its close association with LBW in pregnant women attending antenatal clinic in NAUTH. It was also found that the percentage of LBW was highest in primigravidae.

    Objective. To establish the percentile charts of birth weights for gestational age and sex within the Cameroonian population. Methods. A review of medical records of infants born between January 2007 and December 2011 at the maternities of two hospitals in Cameroon, Central Africa. Multiple pregnancies, births of HIV infected women, stillbirths, and births with major fetal malformations were excluded. The smooth curves of birth weight for gestational age and sex were created using the Gamlss package under R.3.0.1 software. Results. The birth weights of 12837 live birth singleton infants born to HIV negative women between 28 and 42 weeks of gestation were analyzed to construct the birth weight curves for gestational age and sex. The smoothed percentile curves of birth weights for gestational age and sex of Cameroonian infants have demonstrated an increasing slope until 40 weeks and then a plateau. There was a varied difference of distribution in birth weights for gestational age between Cameroonian, Botswanan, American, and French infants. Conclusion. We established the reference curves of birth weights for gestational age and sex for Cameroonians. The difference in birth weight curves noted between Cameroonian, Botswanan, American, and French infants suggests the importance of establishing the regional birth weight norms.

    Background: Urinary tract infection (UTI) is the most common disorder caused by bacterial agents in pregnancy, which can lead to important complications in newborn of such mothers in case of inappropriate diagnosis and treatment. Objectives: The purpose of this study was to study the prevalence of UTI among pregnant women and its complications in their newborns during the birth in the hospitals of Dezful City, Iran, during 2012 - 2013. Patients and Methods: In this cross-sectional retrospective study, 1132 women admitted to Dr. Ganjavian and Ayatollah Nabavi Hospitals in Dezful City, Iran, during 2012 - 2013 were randomly allocated into the case and control groups and were matched based on their age, numbers of pregnancy, sex and diseases of their children. UTI was the only difference between the two groups. Results: Twenty-two thousand six hundred deliveries occurred within the course of this study. Due to UTI, 5% of deliveries led to hospitalization of mothers (1132 patients).Weight and height of newborn infants of mothers afflicted with UTI (P < 0.001) were significantly lower compared to newborns of healthy women (P < 0.001). There was a significant association between the two groups of pregnant women with UTI in terms of type of delivery (normal and caesarean section) (P < 0.008). Conclusions: The lower incidence of UTI in pregnant women compared to other areas of Iran represents the role of climate and weather in the prevalence of UTI. In addition, the increased number of low-birth-weight infants had a remarkable correlation with UTI, which can influence the health of the next generation. PMID:26430526

    Full Text Available In newborns with severe intranatal asphyxia, the hemostasis system adaptation is impaired, thus increasing the risk of bleeding during the first day of life.The purpose of the work was to evaluate the effect of severe birth asphyxia and metabolic acidosis on the newborns' hemostasis system, based on the thromboelastography (TEG findings.Materials and methods. A retrospective analysis of medical records of 40 severely asphyxiated newborns (group 1 and 20 healthy newborns (group 2 was performed. The study was carried out during the first hour of life of the newborns.Results. Infants in group 1 demonstrated a reduced activity of platelets and enzymatic components of the coagulation. The enzymatic phase of the coagulation hemostasis (P<0.001 and the kinetics of clot strength growth significantly decreased in group 1 newborns, as compared to the second group (P<0.001 and P<0.01, respectively. The fibrin network growth rate and its structurization in group 1 newborns was lower than that in group 2 newborns (P<0.05. The platelet activity in group 1 infants was reduced as compared to group 2 (P< 0.05.Fibrinolysis in newborns did not differ at the 30th minute of the study. The correlation analysis demonstrated that decreased pH and Be values and hyperlactacidemia correlated; platelet and coagulation hemostasis parameters were altered with a shift to hypocoagulation. Conclusion. Thromboelastographic study of whole blood samples demonstrated a shift of the hemostatic system to hypocoagulation for both platelet and enzymatic components of hemostasis, without any changes in the clot lysis in severely asphyxiated newborns.

    Ethiopia is among seven high-mortality countries which have achieved the fourth millennium development goal with over two-thirds reduction in under-five mortality rate. However, the proportion of neonatal deaths continues to rise and recent studies reported low coverage of the essential interventions saving newborn lives. In the context of low uptake of health facility delivery, it is relevant to explore routine practices during home deliveries and, in this study, we explored the sequence of immediate newborn care practices and associated beliefs following home deliveries in rural communities in Ethiopia. Between April-May 2013, we conducted 26 semi-structured interviews and 2 focus group discussions with eligible mothers, as well as a key informant interview with a local expert in traditional newborn care practices in rural Basona woreda (district) near the urban town of Debrebirhan, 120 km from Addis Ababa, Ethiopia. The most frequently cited sequence of newborn care practices reported by mothers with home deliveries in the rural Basona woreda was to tie the cord, immediately bath then dry the newborn, practice 'Lanka mansat' (local traditional practice on newborns), give pre-lacteal feeding and then initiate breastfeeding. For 'Lanka mansat', the traditional birth attendant applies mild pressure inside the baby's mouth on the soft palate using her index finger. This is performed believing that the baby will have 'better voice' and 'speak clearly' later in life. Coverage figures fail to tell the whole story as to why some essential interventions are not practiced and, in this study, we identified established norms or routines within the rural communities that determine the sequence of newborn care practices following home births. This might explain why some mothers delay initiation of breastfeeding and implementation of other recommended essential interventions saving newborn lives. An in-depth understanding of established routines is necessary, and community

    This study examines the extent to which the relationship between area socioeconomic position (SEP) and low birth weight (LBW) varies by race and ethnicity. A cross-sectional, secondary data analysis was performed with 1992-1994 Vital Statistics and 1990 U.S. Census data for selected metropolitan areas. Low birth weight (rates were calculated for non-Hispanic Black, Latino, and non-Hispanic White live singleton births. Concentrated poverty was defined as poor persons living in neighborhoods with 40% or more poverty in metropolitan areas. The results showed that the relationship between concentrated poverty and LBW varied by race and ethnicity. Concentrated poverty was significant for Latinos, even when controlling for maternal health and MSA-level factors. By contrast, maternal health characteristics, such as pre-term birth, teen birth and tobacco use, explained much of the variance in African-American and White LBW These findings extend the discussion about race, class, and health disparities to include Latinos and shows how the relationship between SEP and LBW can vary within an ethnic group.

    The goal of nutritional support for very-low-birth-weight (VLBW) infants from birth to term is to match the in utero growth rates; however, this is rarely achieved. We evaluated postdischarge growth patterns and growth failure in 81 Korean VLBW infants through a retrospective study. Weight and height were measured and calculated based on age percentile distribution every 3 months until age 24 months. Growth failure was defined as weight and height below the 10th percentile at 24 months. For the subgroup analysis, small-for-gestational age (SGA) and extremely low birth weight (ELBW) infants were evaluated. The growth patterns based on the Korean, World Health Organization (WHO), or Centers for Disease Control and Prevention (CDC) standard were serially compared over time. At postconception age (PCA) 40 weeks, 47 (58%) and 45 infants (55%) showed growth failure in terms of weight and height, respectively. At PCA 24 months, 20 infants (24%) showed growth failure for weight and 14 (18%) for height. Growth failure rates were higher for the SGA infants than for the appropriate-weight-for-gestational age infants at PCA 24 months ( P =0.045 for weight and P =0.038 for height). Growth failure rates were higher for the ELBW infants than for the non-ELBW infants at PCA 24 months ( P <0.001 for weight and P =0.003 for height). Significant differences were found among the WHO, CDC, and Korean standards ( P <0.001). Advancements in neonatal care have improved the catch-up growth of VLBW infants, but this is insufficient. Careful observation and aggressive interventions, especially in SGA and ELBW infants, are needed.

    Full Text Available The experiment had 2 phases:During the first phase 19 sows were monitored during farrowing; the piglets were numbered according to birth order, they were weighed and there were recorded the time each piglet was born and when it first suckled. There was calculated the time from the beginning of the farrowing until the time each piglet was born (TNPP and the time from birth until the first suckle (TPS. A statistical correlation was established between these parameters.During the second experimental phase, for 49 piglets from 5 sows were determined: birth weight, TPS, glycemia at birth (G0 and after the first suckle (G1, rectal temperature at birth (T0 and after the first suckles (T1. This data was statistically analyzed using the Mann-Whitney U test.Respecting the birth order, TPS is shorter for piglets born last (p<0.05. Average TPS was 23.04±2.49 minutes; during this time glycemia rises from 58.35 mg% to 64.35 mg% and rectal temperature drops from 38.58°C to 37.35°C.

    The aims of the study are (i) to understand inter-zone and interstate variation of low birth weight (LBW) and (ii) to determine the key variables to reduce LBW in India. Using the latest National Family Health Survey (NFHS) data of 2005-06 which showed the percentage distribution of LBW infants, ANOVA and post-hoc test were performed to determine the spatial variation of birth weight. The covariates which influence LBW fell into three categories: (i) social variables which included location, mother's education, religion, access of mothers to newspapers, television and family structure; (ii) economic variable namely, the wealth index, and (iii) biological variables which consisted of sex of the children, birth order, and mother's body mass index (BMI). Three models of Logistic regression were carried out to examine the influence of the combinations of these direct and indirect factors. In India, nearly 20% of new borns have LBW. Males have less frequency of LBW than females. The North-east zone has the lowest prevalence of LBW while the north zone has the highest. Mother's education, access to TV and nuclear family, and intake of iron tablets are the most important socio-economic influences on the determination of birth weight in India. It is essential to provide proper diet and nutritional care of mothers during pregnancy. Increased education of mothers through programmes in TV and newspapers articles have significant roles to play in reducing LBW in India.

    Full Text Available Aim &Background: Muslims fast from sunrise to sunset during Ramadan, the 9th lunar month. The duration of fasting varies from 13 to 18 hrs per day. Fasting individuals abstain from drinking liquids and eating foods. Manypregnant women and gynecologists are concerned about the possible complicationsassociated with fasting and effects on fetal health. The aim of this study was to determine the effect of Ramadan fasting on neonatalbirth weight.Materials and Methods: The current historical cohort study was performed on pregnant women attending maternity hospitals in Kashan in 2008. Twofasting and non-fasting groups were compared. Multiple pregnancies and gestational age less than 37 weeks were considered as the exclusion criteria. In fasting and non-fasting groups, age, parity, gestational age, body mass index (BMI, mother's occupation, prenatal care attendance and intended or unintended pregnancy were matched. For the statistical analysis of the data, covariance analysis and SPSS v16.0 were used. Results: In this study, 293 cases were evaluated among whom 31.7% did notfast. In the two groups, the mean age, gestational age, parity and weight gain during pregnancy were not significantly different. The mean birth weight was 3338 g (±498 g and 3343 g (± 339 g in fasting and non-fasting groups respectively. The results showed that the mean birth weight of the neonates in fasting and non-fasting groups was not significantly different (p=0. 931 Conclusion: The results of this study indicated that there is no significant relationship between the neonatal birth weight and maternal fasting during pregnancy. Therefore we declare thatfasting for pregnant women who receive prenatal care has no effects on neonatal birth weight.

    The aim of this study was to analyse the pattern of birth weight (BW) and identify the factors affecting BW and the risk factors of low birth weight (LBW) in Oman. The data for the study came from the 2000 Oman National Health Survey conducted by the Ministry of Health. The survey covered a nationally representative sample of 2037 ever married Omani women of reproductive age. Data on birth weight were gathered from health cards of the infants born within five years before the survey date. The study considered 977 singleton live births for whom data on birth weights were available. LBW was defined as BW less than 2500 g. Descriptive statistics, analysis of variance, multivariate linear regression and logistic regression models were used for data analysis. The mean BW was found to be 3.09 (SD 0.51) kg. BW was found to be significantly lower among the infants with the following characteristics: born in Ad-Dhakhliyah region, born in rural areas, and whose mothers had low economic status, low parity (0-2), and late initiation of antenatal care (ANC) visit. The incidence of LBW was found to be 9% in Oman in 2000. Mother's education, economic status, region of residence, late initiation of first ANC visit and experience of pregnancy complications appeared as the significant determinants of LBW in Oman. In contrast to most other studies, this study demonstrates that mothers with an advanced level of education (secondary and above) are more likely to have infants with LBW in Oman. The study findings highlight the need of intervention for specific groups of women with higher risk of adverse BW outcomes. Copyright © 2015 The Royal Society for Public Health.

The significance level was set as 0.05.Results: Preterm birth (P<0.001, number of primary care during pregnancy (P=0.001, mother’s age (P=0.049, consumption of supplements during pregnancy (P=0.03, and history of substance abuse in mothers (P=0.03 were found to have significant roles in having LBW neonate.Conclusion: Identifying the sociobehavioral risk factors of Preterm labor and modifying them to prevent preterm birth are essential approaches to prevent LBW. Governments should pay special attention to nutritional status of teenage and young girls to have healthy mothers and babies in the future. Women of childbearing age should be screened and educated about risky behaviors. Pregnancy care and support should be delivered to all pregnant women according to the standard methods.Keywords: Low Birth Weight; Risk Factors; Behavior; Preterm Labor

    Full Text Available Abstract Background Effect of indoor air pollution (IAP on birth weight remains largely unexplored but yet purported as the most important environmental exposure for pregnant women in developing countries due to the effects of second-hand smoke. We investigated the associations between the determinants of indoor air quality in households and birth weight. Methods A cross-sectional study of 592 mothers and their newborns using postnatal services at the Korle Bu Teaching Hospital located in Accra, Ghana was conducted in 2010 to collect information on characteristics of indoor environment and other potential determinants of fetal growth. Birth weight was recorded from hospital records. Results Household cooking fuel choices and garbage burning practices were determinants of birth weight. Multivariate linear regression analysis adjusting for age, social class, marital status and gravidity of mothers, and sex of neonate resulted in a 243g (95% CI: 496, 11 and 178g (95% CI: 421, 65 reduction in birth weight for use of charcoal, and garbage burning respectively compared with use of LPG only. The estimated reductions in birth weight was not statistically significant. Applying the ordinal scale exposure parameter nonetheless revealed a significant exposure-response relationship between maternal exposures from charcoal use and garbage burning, and birth weight. Generalized linear models adjusting for confounders resulted in a 41% (risk ratio [RR] = 1.41; 95% CI: 0.62, 3.23 and 195% (RR=2.95; 95% CI: 1.10, 7.92 increase in the risk of low birth weight (LBW for use of charcoal, and garbage burning respectively compared with use of LPG only. A combination of charcoal use and household garbage burning during pregnancy on fetal growth resulted in a 429g (95% CI: 259, 599 reduction in birth weight and 316% (RR=4.16; 95% CI: 2.02, 8.59 excess risk of LBW. Sensitivity analysis performed by restricting the analysis to term births produced similar results

    In-Home nursing care of the preterm newborn helps to bring the family situation to normal, promotes breastfeeding and development of the newborn, and enables the reorganization of health care resources. The purpose of this paper is to demonstrate that in-home nursing care of the preterm newborn leads to an increase in weight and a similar morbidity. A total of 65 cases and 65 controls (matched by weight, age and sex) were studied, all of them preterm newborns born in hospital and weighing less than 2100 g at discharge. In-home nursing care was carried out by a pediatrician neonatologist, as well as two nurses specialized in neonatology who made several visits to the home. Weight gain was calculated as g/day and g/Kg/day, comparing the first week of the study with the week prior to the beginning of the study. The groups were comparable. Weight gain in the group with home nursing care was 38 g per day, significantly higher than the weight gain in the control group (31 g/day). The independent predictive variables of the increase in g/Kg/day during the study were in-home nursing care, male gender, breastfeeding less, and not having suffered from a peri-intraventricular hemorrhage. Neonatal morbidity was similar in both groups. In-home care was associated with a greater weight gain of the newborn at home than during their stay in the hospital, and can be considered safe because neonatal morbidity was not increased.

    Evidence suggests that pre-pregnancy body mass index and gestational weight gain have impact on pregnancy and birth weight, yet whether maternal gestational weight gain has a differential effect on the rates of adverse birth weight among women with different pre-pregnancy body mass index categories are unknown. We selected 1617 children matched with their mothers as study subjects. The subjects were divided into three categories: weight gain below the American Institute of Medicine guidelines, weight gain within the American Institute of Medicine guidelines and weight gain above the American Institute of Medicine guidelines. The prevalence of pre-pregnancy underweight and overweight/obese women was 16.3% and 12.3%. And nearly 15.2% of the women had gestational weight gain below American Institute of Medicine guideline, 52.1% of the women had gestational weight gain above American Institute of Medicine guideline. Maternal overweight and obese was associated with increased risk for macrosomia and large-for-gestational age. Women had gestational weight gain below American Institute of Medicine guideline were more likely to have low birth weight and small-for-gestational age than women who had gestational weight gain within American Institute of Medicine guideline. Furthermore, the risks for macrosomia and large-for-gestational age were increased in women with above American Institute of Medicine guideline. And for women with a normal weight before pregnancy, gestational weight gain above the American Institute of Medicine guidelines were associated with higher rates of macrosomia and large-for-gestational age, compared with the women of similar pre-pregnancy weight category but with gestational weight gain within the American Institute of Medicine guidelines. Women with abnormal pre-pregnancy body mass index and gestational weight gain are at risk for adverse birth weight outcomes. Moreover, gestational weight gain has a differential effect on the rates of adverse

    Maternal and newborn deaths occur predominantly in low-resource settings. Community-based packages of evidence-based interventions and skilled birth attendance can reduce these deaths. The Maternal and Newborn Health in Ethiopia Partnership (MaNHEP) used community-level health workers to conduct prenatal Community Maternal and Newborn Health family meetings to build skills and care-seeking behaviors among pregnant women and family caregivers. Baseline and endline surveys provided data on a random sample of women with a birth in the prior year. An intention-to-treat analysis, plausible net effect calculation, and dose-response analysis examined increases in completeness of care (mean percentage of 17 maternal and newborn health care elements performed) over time and by meeting participation. Regression models assessed the relationship between meeting participation, completeness of care, and use of skilled providers or health extension workers for birth care-controlling for sociodemographic and health service utilization factors. A 151% increase in care completeness occurred from baseline to endline. At endline, women who participated in 2 or more meetings had more complete care than women who participated in fewer than 2 meetings (89% vs 76% of care elements; P care completeness (P care were nearly 3 times more likely to have used a skilled provider or health extension worker for birth care. Women who had additionally attended 2 or more meetings with family members were over 5 times as likely to have used these providers, compared to women without antenatal care and who attended fewer than 2 meetings (odds ratio, 5.19; 95% confidence interval, 2.88-9.36; P care by engaging women and family caregivers in self-care and care-seeking, resulting in greater completeness of care and more highly skilled birth care. © 2014 by the American College of Nurse-Midwives.

    The aim of this study was to update our acknowledgment if there is a link between assisted embryo cryopreservation and epigenetics in human? Animal studies have demonstrated epigenetics consequence and especially imprinting disorders due to in vitro culture. In human, it is important to note that after frozen embryo transfer birth weight is significantly increased by 81 to 250g. But these studies cannot identify the reasons of such difference. This review strongly suggests that embryo cryopreservation is responsible for birth weight variations but mechanisms not yet elucidated. Epigenetics is probably one of these but to date, none study is able to prove it. We have to be attentive on a possible link between assisted reproductive technology (ART) and epigenetics reprogrammation. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

    Full Text Available Early diagnosis of Bartter syndrome (BS in the neonatal period is a clinical challenge, more so in an extremely low birth weight (ELBW baby because of the inherent renal immaturity and the associated difficulty in fluid management. However, once a diagnosis is made, the disorder is known to respond well to fluid and electrolyte management, prostaglandin inhibitors, and potassium-sparing diuretics. Herein, we report a case of neonatal BS in a very premature ELBW infant.

    Full Text Available Background: Periodontal infections, which serve as a reservoir of inflammatory mediators, may pose a threat to the fetal-placental unit and cause adverse pregnancy outcomes. Objective: The aim of this study was assessing the periodontal status of women during puerperium and determining the possible relationship between their periodontal disease and low birth weight delivery. Materials and Methods: This was a case-control study. The sample included 88 ex-pregnant women were seen at maternity hospitals of Yazd, Iran. Half of the mothers had low birth babies (LBW (birth weight below 2500g- case group and the others had normal weight babies (>2500g- control group. The mothers’ data were obtained from medical files, interview and periodontal clinical examination carried out up to 3 days after delivery. Bleeding on probing, presence of supra-gingival calculus and CPITN (Community Periodontal Index for Treatment Needs were used for periodontal assessment Results: Among the known risk factors of LBW babies, history of previous LBW infant among case mothers reached statistical significance (p=0.0081, Student t-test. Mothers of LBW infants had less healthy areas of gingiva (p=0.042, and more deep pockets (p=0.0006, Mann-Whitney test. Conclusion: The maternal periodontal disease can be a potential independent risk factor for LBW.

    Low birth weight (LBW) constitutes a major public health problem, both in developed than in developing countries, due to its extent and its strong association with childhood morbidity and mortality. to estimate prevalence of low birth weight and determine its related factors in the Prefectoral Hospital in Mohammedia. We carried out a cross sectional study from May to July 2012 which concerned 713 newborns and theirs mothers. We collected information about socioeconomic and anthropometric factors and characteristics of pregnancy. A multivariate analysis was performed. Among the 713 studied newborns, 38 had LBW; the prevalence of LBW was 5,3% (95% CI: 3,7%-6,9%). Factors significantly associated with LBW in multivariate analysis were: mother age ( OR 9,27; IC95%:2,15-39,85), prematurity (OR 9,34; IC95%:1,29-67,32), twin pregnancy (OR 195,07; IC 95%:30,38-125,39) and gender of new born (OR 5,26; IC 95%:1,61-17,18). Well-balanced diet (OR 0,12; IC 95%:0,04-0,34) and hours of sleep equal or more than 8 per day (OR 0,20; IC 95%:0,07-0,58) were protector factors. Actions of education, screening and treatment of the diseases occurred in the pregnancy are necessary. Facilitating the access of pregnant women to high quality antenatal care, promoting a healthy lifestyle as a balanced diet, fighting against the active and passive smoking and offering a psychological support to the pregnant woman is necessary to reduce the prevalence of LBW and to improve the maternal and child health.

    Extra-uterine growth retardation (EUGR) is associated with an increased risk for cardiometabolic diseases later in life. The aim of the present study was to examine the relationship between early weight change after birth in preterm infants and adiponectin (adn) multimeric complexes. Subjects included 28 preterm infants born between weeks 24 and 33 of gestation. Serum adn multimeric complexes and the anthropometric parameters were measured in preterm infants at birth and at corrected term. Bodyweight (BW) decreased during the first week of life, with birthweight restored at approximately 19 days after birth. Nineteen of the subjects had EUGR at corrected term. Total (T)-adn, high-molecular-weight (H)-adn, and the ratio of H-adn to T-adn (H/T-adn) were significantly elevated at corrected term than at birth. Postmenstrual age, birthweight, birth length and lowest BW after birth were positively correlated with H-adn and H/T-adn. Weight reduction after birth was negatively correlated with H-adn. Age to restore birthweight was negatively correlated with T-adn, H-adn and H/T-adn. Stepwise multiple regression analysis indicated age to restore birthweight as the major predictor of T-adn and H-adn. Early weight changes after birth may alter serum adn level in preterm infants at corrected term. The appropriate nutritional support in the early postnatal period could reduce the prevalence of EUGR and the future risk for cardiometabolic diseases. © 2011 The Authors.

    Heat loss in the newborn after delivery could interfere with post-natal adaptation due to metabolic and hemodynamic instability. Associated perinatal factors and their relationship with morbidity and mortality during the neonatal period have not been systematically studied in our unit. To determine the temperature of very low birth weight (VLBW) infants on admission to our NICU, and to determine the associated perinatal variables, and the association of temperature with morbidity and mortality. Infants born in our maternity from January 2006 to November 2012, with birth weights (BW) 401 g to 1,499 g and/or less than 30 weeks gestational age, were included. A multivariate analysis was performed using the perinatal variables and the temperature on admission, as well as a logistic regression between these and the morbidity-mortality variables, in order to detect any independent associations. A total of 635 infants were included, with a mean (± SD) birth weight and gestational age of 1,137.6 ± 257.6g, and 29.5 ± 2.0 weeks, respectively. The mean admission temperature was 35.8 ± 0.6°C (range: 33.0-37.8°C). The proportion of infants with a temperature < 36°C was 44.4%. Independently associated perinatal variables were chorioamnionitis, birth weight, vaginal delivery, and advanced cardiopulmonary resuscitation (CPR). Admission hypothermia was associated with severe intraventricular haemorrhage (IVH) (grades 3 and 4) (OR: 0.377; 95% CI: 0.221-0.643; P<.001), and mortality (OR: 0.329; 95% CI: 0.208-0.519; P=.012). Hypothermia on admission is frequent among our VLBW infants. Birth weight, vaginal delivery, and advanced CPR were the principal variables associated with hypothermia. A low temperature on admission was related to an increased risk of IVH and mortality. Copyright © 2012 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

    Newborn beef calf vigor is a vital survival characteristic that promotes timely colostrum consumption. Modified APGAR scores intended to identify compromised calves are not widely adopted due to impracticality, inconsistent associations with blood gas disturbances, and unclear recommendations for intervention. The objectives were to: (1) determine differences in at-birth blood parameters between calves that were successful in colostrum consumption by 4h (CC4) compared to those that failed; (2) develop a Beef Calf Vigor Assessment by determining calving characteristics and clinical examination parameters associated with CC4; and (3) evaluate impacts of failed CC4 on transfer of passive immunity and treatment risk. As a predictor for CC4, suckle reflex had the highest specificity (98%), whereas calving ease had the highest sensitivity (89%). Calves with a weak suckle reflex had 41.6 (95% CI: 7.4-787.5) times greater odds of failed CC4 compared to calves with a strong suckle reflex (P24g/L serum IgG; OR=6.4, 95% CI: 1.2-34.4; P=0.02), and higher odds of being treated (OR=2.8, 95% CI: 1.1-7.4; P=0.03) than those that succeeded. Measuring suckle reflex in combination with calving ease was a quick and easy method to assess newborn beef calf vigor. The value of this Beef Calf Vigor Assessment was further emphasized by the negative impacts of failed CC4 on transfer of passive immunity and pre-weaning health. Copyright © 2017 Elsevier Ltd.

    Full Text Available Objective: To assess if pregnant women aged 35 years or older aredifferent from younger women, aged from 21 to 34 years, regardingweight gain during pregnancy, body mass index and birth weight ofthe newborn. Methods: Medical records of pregnant women aged35 years or older, seen at the Hospital do Servidor Público Estadualde São Paulo, were studied. The consecutive records of pregnantwomen aged from 21 to 34 years were used to form the control group.Statistics: Descriptive statistical tests and Student’s t test were used.To compare the means between the groups, the ANOVA test wasused, and a value of p < 0.05 was considered significant. Results:Comparing the two age groups, a significant difference was observedbetween the means of initial weight, final weight, and mean weeklygain in the third trimester. No significant differences were found amongthe pregnant women of the various pre-pregnancy body mass indexor weight gain ranges regarding the number of cesarean sections orthe mean birth weight of the newborns. Among the older pregnantwomen there was a significant, although weak, correlation betweenthe mean weekly weight gain in the third trimester and the newborn’sbirth weight, and between the mean weekly weight gain in the secondand third trimesters and the weight gain during the whole pregnancy.Conclusion: The high educational level and the average income of thisgroup were able to guarantee an appropriate nutrition. The older meanage of these pregnant women was consistent with their schooling andcould explain their good compliance with prenatal directions. Theseresults allow reassuring women who become pregnant in this period oflife that they can have a good perinatal outcome, provided they followthe prenatal care directions.

    Full Text Available The infant with Low Birth Weight (LBW was one of the risk factors that contributed to the high infant mortality, especially in the neonatal period. About 17% from 25 millions birth each year in the world are infant with LBW. LBW could be caused by multifactor that were maternal factors (maternal age, birth interval, parity, anemia, social-economic and behaviour, fetus factor, placental factor, and environmental factor. The research aims was to analyze the risk factors correlated with incidence of LBW. This research was an observational  research with case-control design. The number of samples in this research were 120 mothers who delivered in working area of RSIA Kendangsari in 2014. The subjects were selected used systematic random method. The independent variabels in this research were maternal age, education level, employment status, birth interval, parity, age pregnancy, multiple pregnancy, hypertension, and anemia, while the dependent variable in this research was LBW. Based on correlation analysis used Chi-square test showed there were not significant correlation (p>0,05 between birth interval and parity with LBW cases and there were significant correlations (p<0,05 between age pregnancy, hypertension during pregnancy and anemia with LBW cases. Odds Ratio (OR were 13,571 on age pregnancy, 2,224 on multiple pregnancy,2,753 on hypertension and 4,030 on anemia. The conlusion showed that the risk factors of LBW cases were age pregnancy, multiple pregnancy, hypertension and anemia. While maternal age, education level, employment status, birth intervaland parity were not had any correlation with LBW cases. Keywords: LBW, risk factors, babies, maternal, pregnancy

    We analyzed a nationwide registry of all pregnancies in Uruguay during 2007-2013 to assess the impact of three types of tobacco control policies: (1) provider-level interventions aimed at the treatment of nicotine dependence, (2) national-level increases in cigarette taxes, and (3) national-level non-price regulation of cigarette packaging and marketing. We estimated models of smoking cessation during pregnancy at the individual, provider and national levels. The rate of smoking cessation during pregnancy increased from 15.4% in 2007 to 42.7% in 2013. National-level non-price policies had the largest estimated impact on cessation. The price response of the tobacco industry attenuated the effects of tax increases. While provider-level interventions had a significant effect, they were adopted by relatively few health centers. Quitting during pregnancy increased birth weight by an estimated 188 g. Tobacco control measures had no effect on the birth weight of newborns of non-smoking women. Copyright © 2015 Elsevier B.V.

    To review the results of a quality improvement (QI) project to improve admission temperatures of very low birth weight inborn infants. The neonatal intensive care unit at Lucile Packard Children's Hospital underwent a QI project to address hypothermic preterm newborns by staff education and implementing processes such as polyethylene wraps and chemical warming mattresses. We performed retrospective chart review of all inborn infants with birth weight project. The improvement was consistent and persisted over a 15-month period. After risk adjustment, the strongest predictor of hypothermia was being born in the period before implementation of the QI project (odds ratio 8.12, 95% confidence interval 4.63, 14.22). Although cesarean delivery was a strong risk factor for hypothermia prior to the project, it was no longer significant after the project. There was no significant difference in death or intraventricular hemorrhage detected between periods. There was a significant improvement in admission temperatures after a QI project, which persisted beyond the initial implementation period. Although there was no difference in mortality or intraventricular hemorrhage rates, we did not have sufficient power to detect small differences in these outcomes.

    Full Text Available Background: Kangaroo Mother Care (KMC is dened as skin-to-skin contact between a mother and her newborn baby derived from practical similarities to marsupial care giving, proximately exclusive breastfeeding and early discharge from hospital. This concept was proposed as an alternative to conventional methods of care for low birth weight (LBW infants, and in replication to quandaries of earnest overcrowding in Neonatal Intensive Care Units (NICUs. KMC essentially utilizes the mother as a natural incubator Aim and Objectives: The aim was to assess the feasibility, acceptability and the effectiveness of KMC in LBW infants. It avoids agitation routinely experienced in busy ward. Material and Methods: A pilot open-labeled quasi-randomised clinical trial was conducted in Level III NICU of a teaching institution. 60 newborn infants <2500 g, meeting inclusion criteria were alternatively randomised into two groups: Kangaroo Mother Care (KMC and Conventional Methods of Care (CMC.

    Japan, which currently maintains the highest life expectancy in the world and has experienced an impressive gain in adult height over the past century, has suffered a dramatic twofold increase in low birth weight (LBW) births since the 1970s. We observed secular trends in birth characteristics using 64 115 249 live births included the vital statistics (1969-2014), as well as trends in average height among 3 145 521 adults born between 1969 and 1996, included in 79 surveys conducted among a national, subnational or community population in Japan. LBW rates exhibited a U-shaped pattern showing reductions until 1978-1979 (5.5%), after which it increased. Conversely, average adult height peaked for those born during the same period (men, 171.5 cm; women, 158.5 cm), followed by a reduction over the next 20 years. LBW rate and adult height showed a strong inverse correlation (men, r=-0.98; women, r=-0.88). A prediction model based on birth and economical characteristics estimated the national average of adult height would continue to decline, to 170.0cm (95% CI 169.6 to 170.3) for men and 157.9cm (95% CI 157.5 to 158.3) for women among those born in 2014. Adult height in Japan has started to decline for those born after 1980, a trend that may be attributed to increases in LBW births over time. Considering the known association between shorter adult height and adverse health outcomes, evidence of population-level decline in adult health due to long-term consequences of increasing LBW births in Japan is anticipated. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    To construct new Korean reference curves for birth weight by sex and gestational age using contemporary Korean birth weight data and to compare them with the Lubchenco and the 2010 United States (US) intrauterine growth curves. Data of 2,336,727 newborns by the Korean Statistical Information Service (2008-2012) were used. Smoothed percentile curves were created by the Lambda Mu Sigma method using subsample of singleton. The new Korean reference curves were compared with the Lubchenco and the 2010 US intrauterine growth curves. Reference of the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles birth weight by gestational age were made using 2,249,804 (male, 1,159,070) singleton newborns with gestational age 23-43 weeks. Separate birth weight curves were constructed for male and female. The Korean reference curves are similar to the 2010 US intrauterine growth curves. However, the cutoff values for small for gestational age (reference curves for birth weight show a different pattern from the Lubchenco curves, which were made from white neonates more than 60 years ago. Further research on short-term and long-term health outcomes of small for gestational age babies based on the new Korean reference data is needed.

    mortality. This study aims to examine contribution of low birth weight on neonatal mortality in Indonesia. Methods: Data from the Indonesia Demographic and Health Survey (IDHS conducted in 2012 were used in the analysis. A total of 18021 live births in the last five years preceding the survey were reported from the mothers. Completed information of their children (14837 children were taken for this analysis. The adjusted relative risk with cox proportional hazard regression analysis were used to assess the strength of association to neonatal mortality. Results: Children born in low birth weight were 9.89-fold higher risk of neonatal mortality compared to children born in normal weight [adjusted relative risk (aRR = 9.89; 95% confidence interval (CI: 7.41 – 13.19; P = < 0.0001]. Children delivered from younger mothers (aged 15 - 19 years had 94% higher risk of neonatal mortality compared to children delivered from mothers aged 20-35 years. Working mothers had 81% higher risk of neonatal mortality compared to unemployed mothers. Conclusion: Children born in a low birth weight and born from younger mothers had higher risk of neonatal mortality. Appropriate care and treatment for children born in low birth weight is needed to prolonged survival rates of the children.

    To determine the actual nutritional intake of very low birth weight infants and their growth outcome during the first month of life. Additionally, we identified factors that account for a negative neonatal outcome in this population. A case-series study was conducted in a tertiary hospital in Lima, Peru between 2011 and 2012 and the data was obtained from medical records. No feeding protocol was used during this study. Daily fluids, energy and protein intakes were documented and weekly weight z-scores were calculated. A logistic regression analysis was used to identify factors for an adverse outcome, defined as neonatal mortality or extra-uterine growth restriction, during the first 28 days of life. After applying selection criteria, 76 participants were included. The nutritional intakes were similar to standard values seen in the literature, but protein intakes were suboptimal in all of the four weeks. Birth weight z-score was associated with an adverse outcome (p=0.035). It was determined that having a birth weight z-score under -1.09 predicted a negative outcome with an area under the curve of 96.8% [93.5%, 100%] with a 95% confidence interval. Protein intakes are widely deficient in the population of this study. Nevertheless, an adverse outcome during the neonatal period is more associated with a poor birth weight z-score than nutrition-related factors.

    Full Text Available BACKGROUND The aim of the study is to study the effect of kangaroo mother care(KMC on preterm and LBW neonates’ vital parameters like temperature, respiratory rate, heart rate and oxygen saturation, establishment of breastfeeding and weight gain, morbidity and mortality, outcome in intramural and extramural neonates. MATERIALS AND METHODS Hospital-based prospective study, Katuri Medical College and Hospital, 300 newborns shifted to KMC ward. In our study group, female newborns were more than male newborns. Inborn were more than outborn, late preterm more than early preterm and term neonates. A significant increase in axillary temperature, increase in respiratory rate, decrease in heart rate and increase in oxygen saturation was seen in neonates. Higher proportion of neonates achieved transition from predominant expressed breast milk consumption to predominant direct breastfeeding during hospital stay. RESULTS The study showed significantly mean weight gain per day during in hospital KMC of 20 g/kg/day. Mean age when neonates started to gain weight was 8.5 days. Neonates were discharged early as they met our discharge criteria with mean age being 11.6 days. Morbidity of neonates requiring NICU admissions apart from LBW in our study were hyperbilirubinaemia (49.9%, sepsis (19.4%, respiratory illness (7.8% and hypothermia (6.4%. During KMC stay, sepsis and NEC seen in 2 each, apnoea, PDA, jaundice in one each and maternal acceptance of KMC was good. During follow up, it was observed that all neonates were exclusively breastfed and the rate of weight gain (148 g/week was satisfactory with an exception that only 8 requiring hospitalisation and only 1 death due to severe infection. The response of the family and/or the father was supportive. CONCLUSION KMC sustains improvement in LBW neonates’ physiological parameters and accelerates growth pattern. Practice of KMC promote breastfeeding, shorten hospital stay without compromising survival, growth

    Preterm and low birth weight tend to occur as a direct result of prenatal risky behaviors, diseases, as well as fetal exposure to harmful social and environmental factors. The present study aimed to investigate the relationship between job style and preterm low birth weight. The present case-control study was conducted in the Kamali hospital, Teheran, Iran in 2014. Participants included 156 mothers having a gestational age of less than 37 weeks and infants weighing less than 2500 gm. Additionally, the control group consisted of 433 mothers with a gestational age of over 37 weeks and having infants weighing between 2500-4000 gm. The data were collected using the Mother's Lifestyle Scale (MLS) during pregnancy based on recognized social determinants of health and those developed by the researchers. The domain of the mother's job style was assessed using a questionnaire consisting of 18 items on topics such as working conditions, job satisfaction, and perceived employer empathy. Higher overall scores in this instrument indicate the mother's poorer job style. The data were analyzed using SPSS version 16 and Lisrel version 8.8 through a statistical path analysis. The model fit indices indicated that there was found to be high favorability, demonstrated that the model fit and that there were rational relationships (CFI=1, RMSEA=0.00), and showed that on the direct path that the mother's job style had the most adverse effect (B=-0.3) with weight gain during pregnancy showing the most positive effect (B=0.16) on PLBW. The mother's level of education was found to be the only variable that affected PLBW negatively in both the direct and indirect paths through the mother's job style and household income (B=-0.17). According the path analysis model, job style has a direct influence on preterm low birth weight. Thus, special consideration should be placed on aspects surrounding a mother's job situation in order to prevent any adverse effects.

    Birth weight (BW) predicts many health outcomes, but the relative contributions of genes and environmental factors to BW remain uncertain. Some studies report stronger mother-offspring than father-offspring BW correlations, with attenuated father-offspring BW correlations when the mother is stunted. These findings have been interpreted as evidence that maternal genetic or environmental factors play an important role in determining birth size, with small maternal size constraining paternal genetic contributions to offspring BW. Here we evaluate mother-offspring and father-offspring birth weight (BW) associations and evaluate whether maternal stunting constrains genetic contributions to offspring birth size. Data include BW of offspring (n = 1,101) born to female members (n = 382) and spouses of male members (n = 275) of a birth cohort (born 1983-84) in Metropolitan Cebu, Philippines. Regression was used to relate parental and offspring BW adjusting for confounders. Resampling testing was used to evaluate whether false paternity could explain any evidence for excess matrilineal inheritance. In a pooled model adjusting for maternal height and confounders, parental BW was a borderline-significantly stronger predictor of offspring BW in mothers compared to fathers (sex of parent interaction p = 0.068). In separate multivariate models, each kg in mother's and father's BW predicted a 271±53 g (ppaternity rates of >25% and likely 50% would be needed to explain these differences. There was no interaction between maternal stature and maternal BW (interaction p = 0.520) or paternal BW (p = 0.545). Each kg change in mother's BW predicted twice the change in offspring BW as predicted by a change in father's BW, consistent with an intergenerational maternal effect on offspring BW. Evidence for excess matrilineal BW heritability at all levels of maternal stature points to indirect genetic, mitochondrial, or epigenetic maternal contributions to offspring

    Full Text Available Poor maternal nutrition is a major contributor to the high incidence of low birth weight deliveries in developing countries. This study aimed to assess the impact of second trimester maternal dietary intake on gestational weight gain and neonatal birth weight. A longitudinal study was conducted in a tertiary care hospital in Sri Lanka. Participants were 141 pregnant women at 18–24 weeks gestation who were followed up until delivery. Maternal dietary intake was assessed using a validated Food Frequency Questionnaire at 21.1 ± 1.8 gestational weeks. Gestational weight gain was examined at the end of 28 weeks gestation and at the end of pregnancy. Energy and nutrient intakes were calculated using NutriSurvey 2007 (EBISpro, Willstaett, Germany nutrient analysis software, modified for Sri Lankan foods. The mean total gestational weight gain of women with low carbohydrate intake (229–429 g/day was 2.2 kg less than that of women with moderate carbohydrate intake (430–629 g/day (95% confidence interval (CI 0.428–4.083 kg; p = 0.016. Similarly, babies of women with low carbohydrate intake were 312 g lighter compared with those of women with a moderate carbohydrate intake (95% CI 91–534 g; p = 0.006. Our results suggest that second trimester maternal carbohydrate intake has significant impacts on total gestational weight gain and neonatal birth weight.

    This review article provides an overview of the levels, trends and some possible explanations for the increasing rate of low birth weight (LBW) infants in Oman. LBW data from national health surveys in Oman, and published reports from Oman’s Ministry of Health and the World Health Organization were collected and assessed between January and August 2014. Oman’s LBW rate has been increasing since the 1980s. It was approximately 4% in 1980 and had nearly doubled (8.1%) by 2000. Since then, it has shown a slow but steady rise, reaching 10% in recent times. High rates of consanguinity, premature births, number of increased pregnancies at an older maternal age and changing lifestyles are some important factors related to the increasing rate of LBW in Oman. The underlying causes of this increase need to be understood and addressed in obstetric policies and practices in order to reduce the rate of LBW in Oman. PMID:26052449

    2012-10-01

    Full Text Available Terlipressin, a synthetic long-acting analogue of vasopressin, has been investigated as a second line vasopressor in adults and children with refractory septic shock, i.e. not responding to fluid resuscitation and high-dose catecholamine administration. Little experience is available about the safety and efficacy of terlipressin in term and preterm newborns. We report the case of an extremely low birth weight infant with severe septic shock, unresponsive to fluids, noradrenalin and hydrocortisone, in whom terlipressin was attempted as a rescue drug. Despite three doses of terlipressin, administered 6-hourly, the patient remained profoundly hypotensive and eventually died. Further studies are required before any recommendation on the use of terlipressin in term or preterm newborns with septic shock can be made.

    To investigate the effects of state minimum wage laws on low birth weight and infant mortality in the United States. We estimated the effects of state-level minimum wage laws using a difference-in-differences approach on rates of low birth weight (minimum wage above the federal level was associated with a 1% to 2% decrease in low birth weight births and a 4% decrease in postneonatal mortality. If all states in 2014 had increased their minimum wages by 1 dollar, there would likely have been 2790 fewer low birth weight births and 518 fewer postneonatal deaths for the year.

    Full Text Available Background/Aims: Fetal metabolism may be changed by the exposure to maternal factors, and the route to obesity may already set in utero. Cord blood metabolites might predict growth patterns and later obesity. We aimed to characterize associations of cord blood with birth weight, postnatal weight gain, and BMI in adolescence. Methods: Over 700 cord blood samples were collected from infants participating in the German birth cohort study LISAplus. Glycerophospholipid fatty acids (GPL-FA, polar lipids, non-esterified fatty acids (NEFA, and amino acids were analyzed with a targeted, liquid chromatography-tandem mass spectrometry based metabolomics platform. Cord blood metabolites were related to growth factors by linear regression models adjusted for confounding variables. Results: Cord blood metabolites were highly associated with birth weight. Lysophosphatidylcholines C16:1, C18:1, C20:3, C18:2, C20:4, C14:0, C16:0, C18:3, GPL-FA C20:3n-9, and GPL-FA C22:5n-6 were positively related to birth weight, while higher cord blood concentrations of NEFA C22:6, NEFA C20:5, GPL-FA C18:3n-3, and PCe C38:0 were associated with lower birth weight. Postnatal weight gain and BMI z-scores in adolescents were not significantly associated with cord blood metabolites after adjustment for multiple testing. Conclusion: Potential long-term programming effects of the intrauterine environment and metabolism on later health cannot be predicted with profiling of the cord blood metabolome.

Methods: probabilistic sample, by conglomerates, with 17 daycare centers (of a total of 59 composing a final sample of 479 children. We used Z-score of Body Mass Index (zBMI ≥ +1 and ≥ +2, respectively, to identify preschool children with risk of overweight and excess weight (overweight or obesity. The arm muscle area (AMA and the arm fat area (AFA were estimated from measurements of arm circumference, triceps skin fold thickness. Results: the prevalence of risk of overweight was 22.9% (n=110 and excess weight was 9.3% (n=44. The risk of overweight and excess weight in children did not show correlation between BW and AFA, but it did with adjusted arm muscle area (AMAa (rp= 0.21; p= 0.0107. The analysis of the group with excess weight alone also showed a positive correlation between BW and AMAa (rp= 0.42; p= 0.0047. Conclusion: among overweight children, lower BW is associated with a lower arm muscle area in early preschool age, regardless of the fat arm area presented by them.

    2016-01-01

    Gestational weight gain (GWG) has in numerous studies been associated with offspring birth weight (BW) and childhood weight. However, these associations might be explained by genetic confounding as offspring inherit their mother's genetic potential to gain weight. Furthermore, little is known about...... whether particular periods of pregnancy could influence offspring body weight differently. We therefore aimed to explore total and trimester-specific effects of GWG in monozygotic (MZ) twin mother-pairs on their offspring's BW, weight at 1 year and body mass index (BMI) at 5 and 10 years. MZ twin mothers...... statistically weak, suggested no associations between GWG and offspring weight or BMI during infancy or childhood. Our study suggests that total, and possibly also second and third trimester, GWG are associated with offspring BW when taking shared genetic and environmental factors within twin pairs into account...

    Since the implementation of universal newborn screening (NBS) for cystic fibrosis (CF), the timing and magnitude of growth deficiency or its association with correlates of disease among infants with CF who underwent NBS has not been well described. To examine incremental weight gain, linear growth, and clinical features in the first year of life among infants with CF who underwent NBS. The Baby Observational and Nutrition Study (BONUS), a multicenter, longitudinal, observational cohort study, was conducted during regular CF clinic visits in the first 12 months of life at 28 US Cystic Fibrosis Foundation-accredited Care Centers from January 7, 2012, through May 31, 2015. Participants included 231 infants younger than 3.5 months who underwent NBS and had confirmed CF, with a gestational age of at least 35 weeks, birth weight of at least 2.5 kg, and toleration of full oral feeds. Of these, 222 infants (96.1%) had follow-up beyond 6 months of age and 215 (93.1%) completed 12 months of follow-up. Cystic fibrosis. Attained weight and length for age and World Health Organization normative z scores at ages 1 to 6 and 8, 10, and 12 months (defined a priori). Of the 231 infants enrolled, 110 infants (47.6%) were female and 121 (52.4%) were male, with a mean (SD) age of 2.58 (0.69) months. BONUS infants had lower than mean birth weights (mean z score, -0.15; 95% CI, -0.27 to -0.04) and higher birth lengths (mean z score, 0.44; 95% CI, 0.26 to 0.62). They achieved normal weight by 12 months, a significant improvement over a prescreening cohort of newborns with CF from 20 years before the contemporary cohort (mean z score increase, 0.57; 95% CI, 0.37-0.77). However, length was lower than the mean at 12 months (mean z score, -0.56; 95% CI, -0.70 to -0.42). Only 30 infants (13.6%) were at less than the 10th percentile of weight for age, whereas 53 (23.9%) were at less than the 10th percentile of length for age at more than half their visits.

    Objective The goals of our study were 1) to estimate the trends in maternal weight gain patterns and 2) to estimate the influence of variation in maternal weight and rate of weight gain over different time periods in gestation on variation in birth weight in African-American and non-African-American gravidas. Study Design and Setting Data from a prospective cohort study in which pregnant women were monitored at multiple time points during pregnancy were analyzed. Maternal weight was measured at three times during pregnancy, preconception (W0); 16-20 weeks gestation (W1); and 30-36 weeks gestation (W2), in a cohort of 435 women with full-term singleton pregnancies. The relationship between gestational age-adjusted birth weight (aBW) and measures of maternal weight and rate of weight gain across pregnancy was estimated using a multivariable longitudinal regression analysis stratified on African-American race. Results The aBW was significantly associated with maternal weight measured at any visit in both strata. For African-American women, variation in aBW was significantly associated with variation in the rate of maternal weight gain in the first half of pregnancy (W01) but not the rate of maternal weight gain in the second half of pregnancy (W12); while for non-African-American women, variation in aBW was significantly associated with W12 but not W01. Conclusion Factors influencing the relationship between aBW and maternal weight gain patterns depend on the context of the pregnancy defined by race. Clinical decisions and recommendations about maternal weight and weight gain during pregnancy may need to account for such heterogeneity. PMID:20632908

    Full Text Available Introduction: One of the common problems in neonatal period is jaundice that occurs in the first week of birth in 60% of term and 80% of preterm neonates. In preterm newborn hyperbilirubinaemia is higher, persistent, longer, and more likely to be associated with neurological injury than term neonates. The purpose of this study was to determine Prophylactic effect of zinc sulphate on hyperbilirubinemia in premature very low birth weight neonates. Method and Material: Sixty Newborns who admitted in our NICU which had inclusion criteria were eligible in this trial. Included neonates were randomly placed in two groups (case and control and before intervention the total serum bilirubin (TSB was measured at second day. The participant received either 20 mg of zinc sulfate or placebo through NG-tube divided in two doses till day seven of age. Then total and indirect bilirubin was measured at 3ed, 5th and 7th day of life. If any of newborns in duration of hospitalization develop clinical jaundice, after assessment of bilirubin, need for phototherapy was evaluated based on phototherapy and exchange schedule as described by the American Academy of Pediatrics guidelines. The termination point of phototherapy was defined as a bilirubin level less than 50 percent of starting point. After gathering Data, they were analyzed using SPSS software (version 11.5 and T-test, Chi-square and repeated measurement tests. Results: Seventy eight patients enrolled in this trial that 18 cases were excluded and the remaining cases divided into two equal groups (N=30 in each group. Demographic condition was similar in two groups. There were no different between two groups in decreasing total serum bilirubin and duration of phototherapy. Conclusion: This study showed that zinc sulfate has no preventing effective in hyperbilirubinemia in preterm very low birth weight neonates. It has also no effect on duration of phototherapy.

    Background Premature infants are at high risk for developmental delay and cognitive dysfunction. Besides medical conditions, growth restriction is regarded as an important risk factor for cognitive and neurodevelopmental dysfunction throughout childhood and adolescence and even into adulthood. In this study, we analyzed the relationship between post-discharge body weight and psychomotor development using a nationwide dataset. Materials and methods This was a nationwide cohort study conducted in Taiwan. Total of 1791 premature infants born between 2007 and 2011 with a birth weight of less than 1500 g were enrolled into this multi-center study. The data were obtained from the Taiwan Premature Infant Developmental Collaborative Study Group. The growth and neurodevelopmental evaluations were performed at corrected ages of 6, 12 and 24 months. Post-discharge failure to thrive was defined as a body weight below the 3rd percentile of the standard growth curve for Taiwanese children by the corrected age. Results The prevalence of failure to thrive was 15.8%, 16.9%, and 12.0% at corrected ages of 6, 12, and 24 months, respectively. At corrected ages of 24 months, 12.9% had low Mental Developmental Index (MDI) scores (MDIneurodevelopmental impairment. Post-discharge failure to thrive was significantly associated with poor neurodevelopmental outcomes. After controlling for potential confounding factors (small for gestational age, extra-uterine growth retardation at discharge, cerebral palsy, gender, mild intraventricular hemorrhage, persistent pulmonary hypertension of newborn, respiratory distress syndrome, chronic lung disease, hemodynamic significant patent ductus arteriosus, necrotizing enterocolitis, surfactant use and indomethacin use), post-discharge failure to thrive remained a risk factor. Conclusion This observational study observed the association between lower body weight at corrected age of 6, 12, and 24 months and poor neurodevelopmental outcomes among VLBW

    To evaluate the association between rate of gestational weight gain and preterm birth varying prepregnancy body mass indices and trimester. Data from Maternal and Newborn's Health Monitoring System on 17475 pregnant women who delivered live singletons at ≥ 28 weeks of gestation between October 2013 and September 2014 from 12 districts/counties of 6 provinces in China and started prenatal care at ≤ 12 weeks of gestation was analyzed. Gestational weight gain was categorized by rate of weight gain during the 2(nd) and 3(rd) trimester, based on the 2009 Institute of Medicine guidelines. Multivariable binary logistic regression models were conducted to investigate the association between rate of gestational weight gain and preterm birth stratified by prepregnancy body mass indices and trimester. Excessive weight gain occurred in 57.9 % pregnant women, and insufficient weight gain 12.5 %. Average rate of gestational weight gain in 2(nd) and 3(rd) trimester was independently associated with preterm birth (U-shaped), and the association varied by prepregnancy body mass indices and trimesters. In underweight women, excessive gestational weight gain was positively associated with preterm birth (OR 1.93, 95 % confidence interval (CI): 1.29- 2.88) when compared with women who gained adequately. While in overweight/obese women, insufficient gestational weight gain was positively associated with preterm birth (OR 3.92, 95 % CI: 1.13-13.67). When stratifying by trimester, we found that excessive weight gain in 3(rd) trimester had a significantly positive effect on preterm birth (OR 1.27, 95 % CI: 1.02-1.58). Excessive gestational weight gain among underweight pregnant women, insufficient gestational weight gain among overweight/obese women and excessive gestational weight gain in 3(rd) trimester were important predictors of preterm birth.

    Full Text Available Examinations were made in 35 boys and 39 girls with extremely low birth weight in order to identify gender-related clinical and immunological features. A comparison group consisted of 31 full-term newborns with early uncomplicated adaptation. The investigators determined the number of lymphocyte subpopulations and cytokine-producing cells (CD3+INF-γ+, CD3+IL-4+ by flow cytometry and the serum levels of cytokines (IL-4, IFN-γ and neopterin by enzyme immunoassay. A study of immunological parameters revealed that the boys had a smaller number of CD3+, CD4+, and CD8+ subpopulations, a reduced content of CD3+IL-4+ cells at birth, and low IL-4 production on the first day of life compared to the full-term neonates. The girls were recorded to have higher levels of neopterin and B cells on the first day of life, the quantitative characteristics of T lymphocytes were consistent with those in the full-term infants. The findings are indicative of the greater functional immaturity of the immune system in the preterm boys.

    Studies examining the association between maternal pesticide exposure and low birth weight yield conflicting results. The authors examined the association between maternal pesticide use and birth weight among women in the Agricultural Health Study, a large study of pesticide applicators and their spouses in Iowa and North Carolina. The authors evaluated self-reported pesticide use of 27 individual pesticides in relation to birth weight among 2246 farm women whose most recent singleton birth occurred within 5 years of enrollment (1993-1997). The authors used linear regression models adjusted for site, preterm birth, medical parity, maternal body mass index, height, and smoking. The results showed that mean infant birth weight was 3586 g (+/- 546 g), and 3% of the infants were low birth weight (birth weight. Ever use of the pesticide carbaryl was associated with decreased birth weight (-82 g, 95% confidence interval [CI] = -132, -31). This study thus provides limited evidence about pesticide use as a modulator of birth weight. Overall, the authors observed no associations between birth weight and pesticide-related activities during early pregnancy; however, the authors have no data on temporal specificity of individual pesticide exposures prior to or during pregnancy and therefore cannot draw conclusions related to these exposure windows. Given the widespread exposure to pesticide products, additional evaluation of maternal pregnancy exposures at specific time windows and subsequent birth outcomes is warranted.

    Modern adverse birth outcomes may partially result from mechanisms evolved to evaluate environmental conditions and regulate maternal investment trade-offs. Male scarcity in a population is associated with a cluster of characteristics related to higher mating effort and lower paternal investment. We predicted that modern populations with male scarcity would have shorter gestational times and lower birth weights on average. We compared US Centers for Disease Control and Prevention county-aggregated year 2000 birth records with US Decennial Census data. We combined these data in a path model with the degree of male scarcity and known socio-economic predictors of birth outcomes as exogenous predictors of prematurity and low birth weight, with single mother households as a proportion of families with children as a mediator (N = 450). Male scarcity was directly associated with higher rates of low birth weight. Male scarcity made significant indirect predictions of rates of prematurity and low birth weight, as mediated by the proportion of families headed by single mothers. Aggregate socio-economic status also indirectly predicted birth outcomes, as mediated by the proportion of families headed by single mothers, whereas the proportion African American retained both direct and indirect predictions of adverse birth outcomes. Male scarcity influences life history tradeoffs, with consequences for important social and public health issues such as adverse birth outcomes. Copyright © 2013 Wiley Periodicals, Inc.

    Objective  To study the characteristics of very low birth weight (VLBW) infants receiving glycerin suppositories (GS) and evaluate the association of GS use with outcomes. Study Design  This is a retrospective study of VLBW infants admitted to a level III neonatal intensive care unit. Infants with birth weight between 500 and 1,499 g were evaluated. We evaluated the frequency of GS use and compared the characteristics and outcomes of the GS group with the no-GS group. Multivariate analyses controlling for gestational age and small for gestational age status were performed to study the effect of GS on outcomes. Results  A total of 1,073 infants were included in the study. Out of those, 527 (49.1%) infants received GS. Incidence of necrotizing enterocolitis was not significantly different between the two groups, while days to reach full enteral feeds and length of hospital stay were significantly longer in the GS group. Conclusion  Frequent use of GS warrants further prospective studies to evaluate its safety and efficacy in view of our study showing association with longer time to reach full enteral feeds. We speculate that GS use could be a marker for gastrointestinal dysmotility and hence the association with unfavorable clinical outcomes.

    Neonatal hearing impairment is a common disorder with a prevalence of 1 to 2‰ worldwide, with significant consequences on overall development when rehabilitated too late. New-born hearing screening has been implemented in the 1990s in most European countries and the USA. The Upper-Normandy region of France has been conducting a pilot program since 1999. The aim of this prospective study was to evaluate and critically analyse it. The Upper-Normandy universal new-born hearing screening program is performed in two steps. Between 1999 and 2004, first, we administered a Transient Evoked Oto Acoustic Emission (TEOAE) test was administered a few days after birth for healthy newborns without risk factors. For newborns admitted to a neonatal intensive care unit (NICU) or presenting risk factors, was administered an automated auditory brainstem response (AABR) test prior to discharge. Second, newborns who failed the initial hearing screening were retested as outpatients using TEOAE. Since 2004, infants who failed the initial screen were tested with AABR 3 to 4 weeks later as outpatients, providing an opportunity to compare the two protocols. Overall screening coverage in the Upper-Normandy region is 99.8%. First step coverage is 99.58% in well-infant nurseries and 97.09% in the NICU. The test-retest procedure during the first step and the use of AABR for the second resulted in higher follow-up rates and lower false positive rates. The Upper-Normandy region universal newborn hearing screening program facilitated diagnosis and rehabilitation of infants before age of 9 months, most notably when severe to profound hearing impairment was found.

      To assess and quantify cleft team practices with regard to nutritional support in the neonatal period Design :  Retrospective review.   Tertiary pediatric hospital.   One hundred consecutive newborn patients with a diagnosis of cleft lip and/or cleft palate between 2009 and 2012.   Birth weight, cleft type, initial cleft team weight measurements, initial feeding practices, recommended nutritional interventions, and follow-up nutritional assessments.   All patients in the study were evaluated by a registered dietitian and an occupational feeding therapist. Average birth weight and average age at the first cleft team visit were similar for each cleft type: cleft lip (CL), cleft lip and palate (CLP), and cleft palate (CP). The calculated age (in days) for return to birth weight was significantly different between cleft types: CL = 13.58 days, CLP = 15.88 days, and CP = 21.93 days. Exclusive use of breast milk was 50% for patients with CL, 30.3% for patients with CLP, and 21.4% for patients with CP. Detailed nutritional interventions were made for 31 patients at the first visit: two with CL, 14 with CLP, and 15 with CP.   Distinct differences were seen in neonatal weight gain between cleft types. There was significantly greater total weight gain for patients with CL at their first visit and significantly slower return to birth weight for patients with isolated CP. Patients with CL required far fewer interventions at the initial assessment and were more likely to be provided breast milk exclusively or in combination with formula. Infants with CP were far less likely to receive any breast milk. Patients with CLP and CP required frequent nutritional interventions.

    Exposure to air pollution has been demonstrated to increase the risk of preterm birth and low birth weight. We examined whether proximity to major roads (as a marker of exposure to air pollution) is associated with increased placenta/birth weight ratio (as a biomarker of the placental transport function). Data on parental characteristics and birth outcomes were extracted from the database maintained by a major hospital in Shizuoka Prefecture, Japan. We restricted the analysis to mothers who delivered liveborn single births from 1997 to 2008 (n = 14,189). Using geocoded residential information, each birth was classified according to proximity to major roads. We examined the association between proximity to major roads and the placenta/birth weight ratio, using multiple linear regression. Proximity to major roads was associated with higher placenta/birth weight ratio. After adjusting for potential confounders, living within 200 m of a major road increased the ratio by 0.48% (95% CI = 0.15 to 0. 80). In addition, proximity to major roads was associated with lower placenta weight and birth weight. These observed associations were stronger among participants living closer to major roads. Exposure to traffic-related air pollution is associated with higher placenta/birth weight ratio. Impaired placental oxygen and nutrient transport function might be a mechanism for explaining the observed association between air pollution and low birth weight as well as preterm birth.

    Full Text Available Abstract Background Community capacities and resources must be harnessed to complement supply side initiatives addressing high maternal and neonatal mortality rates in Uganda. This paper reflects on gains, challenges and lessons learnt from working with communities to improve maternal and newborn health in rural Uganda. Methods A participatory action research project was supported from 2012 to 2015 in three eastern districts. This project involved working with households, saving groups, sub county and district leaders, transporters and village health teams in diagnosing causes of maternal and neonatal mortality and morbidity, developing action plans to address these issues, taking action and learning from action in a cyclical manner. This paper draws from project experience and documentation, as well as thematic analysis of 20 interviews with community and district stakeholders and 12 focus group discussions with women who had recently delivered and men whose wives had recently delivered. Results Women and men reported increased awareness about birth preparedness, improved newborn care practices and more male involvement in maternal and newborn health. However, additional direct communication strategies were required to reach more men beyond the minority who attended community dialogues and home visits. Saving groups and other saving modalities were strengthened, with money saved used to meet transport costs, purchase other items needed for birth and other routine household needs. However saving groups required significant support to improve income generation, management and trust among members. Linkages between savings groups and transport providers improved women’s access to health facilities at reduced cost. Although village health teams were a key resource for providing information, their efforts were constrained by low levels of education, inadequate financial compensation and transportation challenges.

    Maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) have been reported to be associated with pregnancy outcomes. Due to the nutrition transition in Thailand, the double burden of malnutrition is increasing and this may have negative consequences on birth outcomes. This study aimed to investigate the relationship between pre-pregnancy BMI and GWG with the risks of low birth weight and macrosomia. We performed a secondary analysis of data obtained from an iodine supplementation trial in mildly iodine-deficient Thai pregnant women. Pre-pregnancy BMI was classified using the WHO classification. GWG was categorized using the IOM recommendation. Binary and multinomial logistic regressions were performed. Among 378 pregnant women, the prevalence of pre-pregnancy underweight (BMI=25 kg/m2) were 17.2% and 14.3%, respectively. Normal weight women had the highest median GWG [15.0 (12.0, 19.0) kg] when compared to overweight women [13.2 (9.0, 16.3) kg]. Forty-one percent of women had excessive GWG, while 23% of women gained weight inadequately. Women with a high pre-pregnancy BMI had a 7-fold higher risk of having a macrosomic infant. Women who had excessive GWG were 8 times more likely to deliver a newborn with macrosomia. Both high pre-pregnancy maternal weight and excessive weight gain during pregnancy increase risk of infant macrosomia. Therefore, maintaining normal body weight before and throughout pregnancy should be recommended in order to reduce the risk of excessive infant birth weight and its associated complications.

    To understand the distribution of birth weight among premature infants and the associated social factors. The study population consisted of 97 537 women who delivered singleton live birth of 20 to 41 gestational weeks in 4 counties/cities, Jiangsu and Zhejiang provinces, China from 1995 to 2000. Chi-square test was employed to test the difference of proportions between respective groups. One- way ANOVA was used to test the differences regarding the mean of gestational weeks at the first prenatal visit and the mean of prenatal visits between the two groups. Multivariate logistic regression was conducted to examine the factors associated with premature birth. Women aged 35 years had higher (8.8%) premature incidence than those aged less than 24 years (5.6%), 25 - 29 years (4.6%), or 30 - 34 years (4.5%, P premature incidence than those with height taller than 150 cm (5.0%). Women whose BMI were at least 28 and 24 - 28 had higher (5.5%, 5.5%) premature incidences than those whose BMI were 18.5 - 24.0 (5.0%), premature birth was 6.0% among women without previous pregnancy, higher than that among those women with 4 times of pregnancies (5.7%), 2 times of pregnancies (4.3%), and 3 times of pregnancies (4.0%). Parous women with at least two deliveries had higher (9.3%) premature incidence than the primiparous women (5.2%) and whose women with only one delivery (4.5%, P premature incidence than those who did not receive the service (6.1%). The mean times of prenatal visits among women with premature births was 8.53, less than that of those with full term delivery (10.97). Women with less than four times of prenatal visit had higher (18.9%) premature incidence than those with at least five prenatal visits (4.9%). Multivariate logistic regression showed that premature delivery risk was associated with age, height, BMI, gravidity, parity, early prenatal care, the mean of gestational weeks at first prenatal visit and the mean number of prenatal visits etc. Premature delivery

    Full Text Available Objective: To compare the growth curves from a population from a large city suburban hospital with those of the city of São Paulo, São Paulo State, Brazil. Methods: At Hospital Geral do Grajaú, that serves the high pregnancy risk population lacking health facilities, of low education level and smaller number of prenatal visits and great morbidity, a growth curve was built for the newborns, as the Hospital is provided with updated equipment and personnel. The curve was built from the database available containing information on live births during the 2003 to 2007 period and totaling 9,952 newborns, as their weight at birth and gestational age were taken as parameters. The distribution curves of 3%, 10%, 50% and 90% of the Grajaú were compared to those of the city of São Paulo curve. Results: The curves did not significantly differ from those of the São Paulo curve percentiles, as shown by the mean deviation (Z score calculation, notwithstanding the higher rates for prematurity, low weight, teenager mothers and lack of prenatal visits among the Grajaú population as compared to those of São Paulo. Conclusions: The São Paulo city curve showed to be appropriate for the suburban population despite the existing differences.

    It has been speculated whether maternal immune responses against male-specific minor histocompatibility (H-Y) antigens affect pregnancies negatively. This study explores, on a population level, whether previous births of boys compared with girls are associated with a decrease in birth weight...... of later-born siblings. The population was identified in the Danish Birth Registry and consisted of all Danish women who gave birth to their first-born singleton from 1980 to 1998. The women were followed until 2004, and their subsequent births were recorded. A total of 545,839 second- to fourth......-born children were identified. The authors used linear regression to analyze the association between sex of preceding children and birth weight of subsequent siblings. Brothers compared with sisters reduced the birth weight of later-born siblings. One or two brothers, respectively, reduced the mean birth weight...

    Jaundice is a problem in newborns. There are many maternal and infant-related factors affecting neonatal jaundice. The maternal pre-pregnancy weight, maternal body mass index (BMI) and gestational weight gain may have an effect on the newborn bilirubin levels. We research the effect of the maternal pre-pregnancy weight and gestational weight gain on the bilirubin levels of the newborn infants in the first 2 weeks prospectively. Term and healthy infants who were born between 38 and 42 weeks in our clinic were included in the study. Maternal pre-pregnancy BMIs were calculated. Babies were divided into three groups according to their mothers' advised amount of gestational weight gain. Total serum bilirubin (TSB) values of the newborns were measured in the 2nd, 5th and 15th postnatal days. In our study, the 5th and 15th day capillary bilirubin level of the babies with mothers who gained more weight than the advised amount during pregnancy were found statistically significant higher compared to the other two groups (p mothers who gained more weight than the advised amount were found statistically significant higher compared to the other two groups (p mothers who gained more weight than the advised amount were under risk for newborn jaundice. Therefore, these babies should be monitored more closely for neonatal jaundice and prolonged jaundice.

    Low birth weight is associated with adverse health outcomes. If birth weight records are not available, studies may use recalled birth weight. It is unclear whether this is reliable. We performed a systematic review and meta-analysis of studies comparing recalled with recorded birth weights. We followed the Meta-Analyses of Observational Studies in Epidemiology (MOOSE) statement and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched MEDLINE, EMBASE and Cumulative Index to Nursing and Allied Health Literature (CINAHL) to May 2015. We included studies that reported recalled birth weight and recorded birth weight. We excluded studies investigating a clinical population. Two reviewers independently reviewed citations, extracted data, assessed risk of bias. Data were pooled in a random effects meta-analysis for correlation and mean difference. In total, 40 studies were eligible for qualitative synthesis (n=78,997 births from 78,196 parents). Agreement between recalled and recorded birth weight was high: pooled estimate of correlation in 23 samples from 19 studies (n=7406) was 0.90 [95% confidence interval (CI) 0.87-0.93]. The difference between recalled and recorded birth weight in 29 samples from 26 studies (n=29,293) was small [range -86-129 g; random effects estimate 1.4 g (95% CI -4.0-6.9 g)]. Studies were heterogeneous, with no evidence for an effect of time since birth, person reporting, recall bias, or birth order. In post-hoc subgroup analysis, recall was higher than recorded birth weight by 80 g (95% CI 57-103 g) in low and middle income countries. In conclusion, there is high agreement between recalled and recorded birth weight. If birth weight is recalled, it is suitable for use in epidemiological studies, at least in high income countries.

    Low and high birth weight (BW) are important risk factors for neonatal morbidity and mortality. Gynecologists must therefore accurately predict BW before delivery. Most prediction formulas for BW are based on prenatal ultrasound measurements carried out within one week prior to birth. Although successfully used in clinical practice, these formulas focus on point predictions of BW but do not systematically quantify uncertainty of the predictions, i.e. they result in estimates of the conditional mean of BW but do not deliver prediction intervals. To overcome this problem, we introduce conditionally linear transformation models (CLTMs) to predict BW. Instead of focusing only on the conditional mean, CLTMs model the whole conditional distribution function of BW given prenatal ultrasound parameters. Consequently, the CLTM approach delivers both point predictions of BW and fetus-specific prediction intervals. Prediction intervals constitute an easy-to-interpret measure of prediction accuracy and allow identification of fetuses subject to high prediction uncertainty. Using a data set of 8712 deliveries at the Perinatal Centre at the University Clinic Erlangen (Germany), we analyzed variants of CLTMs and compared them to standard linear regression estimation techniques used in the past and to quantile regression approaches. The best-performing CLTM variant was competitive with quantile regression and linear regression approaches in terms of conditional coverage and average length of the prediction intervals. We propose that CLTMs be used because they are able to account for possible heteroscedasticity, kurtosis, and skewness of the distribution of BWs. © The Author(s) 2014.

    Full Text Available Despite the fact that feeding a very low birth weight (VLBW neonate is a fundamental and inevitable part of its management, this is a field which is beset with controversies. Optimal nutrition improves growth and neurological outcomes, and reduces the incidence of sepsis and possibly even retinopathy of prematurity. There is a great deal of heterogeneity of practice among neonatologists and pediatricians regarding feeding VLBW infants. A working group on feeding guidelines for VLBW infants was constituted in McMaster University, Canada. The group listed a number of important questions that had to be answered with respect to feeding VLBW infants, systematically reviewed the literature, critically appraised the level of evidence, and generated a comprehensive set of guidelines. These guidelines form the basis of this state-of-art review. The review touches upon trophic feeding, nutritional feeding, fortification, feeding in special circumstances, assessment of feed tolerance, and management of gastric residuals, gastro-esophageal reflux, and glycerin enemas.

    Full Text Available Background and Objectives: LBW is the strongest factor related to prenatal, neonatal, postnatal and childhood mortality and morbidity. Air pollution is one of the risk factors that is recently gaining attention. This study was carried out to determine the relationship between the CO ambient and low birth weight in women referring to Tehran hospitals in 2007-2008. Methods: In this historical cohort study 225 pregnant women having lived within 5 kilometers of a monitoring station during pregnancy and referring to selected hospitals in Tehran were investigated. An information questionnaire was used for data collection and sampling was done by multistage sampling and convenience method. Women were assigned to low exposure group and high exposure group based on mean exposure to each pollutant during pregnancy. These two groups were matched with respect to confounding factors. SPSS software version 15, T statistics, 2, Man Withnney, and Relative Risk procedures were used for data analysis.Results: The result showed that 31.6% of CO high exposure group and 7.4% of CO low exposure group had Low birth weight baby. The result also showed a significant relationship between exposure to high amount of CO and LBW (p=0.001. Relative Risk calculated with confidence interval (RR=4/67, CI=(1/76-9/43 was found to be 95% and the amount of attributable risk was 66%.Conclusion: Based on these finding, exposure to carbon monoxide pollution can cause LBW. There should be an educational program about the disadvantages of CO pollutant on pregnant women living in densely populated areas of the city. Moreover, practical approaches should be provided to reduce these pollutants.

    To develop a complete, population-based system for ultrasound-based fetal size monitoring and birth-weight prediction for use in the second and third trimesters of pregnancy. Using 31 516 ultrasound examinations from a population-based Norwegian clinical database, we constructed fetal size charts for biparietal diameter, femur length and abdominal circumference from 24 to 42 weeks' gestation. A reference curve of median birth weight for gestational age was estimated using 45 037 birth weights. We determined how individual deviations from the expected ultrasound measures predicted individual percentage deviations from expected birth weight. The predictive quality was assessed by explained variance of birth weight and receiver-operating characteristics curves for prediction of small-for-gestational age. A curve for intrauterine estimated fetal weight was constructed. Charts were smoothed using the gamlss non-linear regression method. The population-based approach, using bias-free ultrasound gestational age, produces stable estimates of size-for-age and weight-for-age curves in the range 24-42 weeks' gestation. There is a close correspondence between percentage deviations and percentiles of birth weight by gestational age, making it easy to convert between the two. The variance of birth weight that can be 'explained' by ultrasound increases from 8% at 20 weeks up to 67% around term. Intrauterine estimated fetal weight is 0-106 g higher than median birth weight in the preterm period. The new population-based birth-weight prediction model provides a simple summary measure, the 'percentage birth-weight deviation', to be used for fetal size monitoring throughout the third trimester. Predictive quality of the model can be measured directly from the population data. The model computes both median observed birth weight and intrauterine estimated fetal weight.

    Full Text Available Despite increasing professionalism in dog breeding, the physiological range of birth weight in this species remains unclear. Low birth weight can predispose to neonatal mortality and growth deficiencies in humans. To date, the influence of the morphotype on birth weight has never been studied in dogs. For this purpose, an Italian census of birth weight was collected from 3293 purebred pups based on maternal morphotype, size, body weight and breed, as well as on litter size and sex of pups. Multivariate analysis outcomes showed that birth weight (p < 0.001 and litter size (p < 0.05 increased with maternal size and body weight. Birth weight was also influenced by the maternal head and body shape, with brachycephalic and brachymorph dogs showing the heaviest and the lightest pups, respectively (p < 0.001. Birth weight decreased with litter size (p < 0.001, and male pups were heavier than females (p < 0.001. These results suggest that canine morphotype, not only maternal size and body weight, can affect birth weight and litter size with possible practical implications in neonatal assistance.

    OBJECTIVE--To investigate the influence of birth weight on the pronounced social class differences in infant mortality in Britain. DESIGN--Analysis of routine data on births and infant deaths. SETTING--England and Wales. SUBJECTS--All live births and infant deaths, 1983-5. MAIN OUTCOME MEASURE--Mortality in infants by social class, birth weight, and legitimacy according to birth and death certificates. RESULTS--Neonatal and postneonatal mortality (deaths/1000 births) increased with social class. Neonatal and postneonatal mortality was 4.2/1000 and 2.3/1000 respectively for social class I and 6.8/1000 and 5.6/1000 respectively for social class V. Mortality was lower among births registered within marriage (postneonatal 3.5/1000; neonatal 5.2/1000) than among those jointly registered outside marriage (5.1/1000; 6.4/1000); mortality was highest in those solely registered outside marriage (7.2/1000; 7.0/1000). For neonatal mortality the effect of social class varied with birth weight. Social class had little effect on neonatal mortality in low birthweight babies and increasing effect in heavier babies. For postneonatal mortality the effect of social class was similar for all birth weights and was almost as steep as for all birth weights combined. CONCLUSION--Birth weight mediates little of the effect of social class on postneonatal mortality. PMID:1954421

    There is strong evidence that physical activity (PA) has an influence on physical performance in later life. Also, a small body size at birth has been associated with lower physical functioning in older age and both small and high birth weight have shown to be associated with lower leisure time physical activity. However, it is unknown whether size at birth modulates the association between PA and physical performance in old age. We examined 695 individuals from the Helsinki Birth Cohort Study born in Helsinki, Finland between 1934 and 1944. At a mean age of 70.7 years PA was objectively assessed with a multisensory activity monitor and physical performance with the Senior Fitness Test (SFT). Information on birth weight and gestational age was retrieved from hospital birth records. The study participants were divided in three birth weight groups, that is birth weight groups. However, the effect size of the association was large and significant only in men with a birth weight confidence interval 0.37-0.81, Pbirth weight. Our results suggest that men with low birth weight might benefit most from engaging in PA in order to maintain a better physical performance.

  7. Meditations on birth weight: is it better to reduce the variance or increase the mean?

    Science.gov (United States)

    Haig, David

    2003-07-01

    A conceptual model is presented here in which the birth weight distribution is decomposed into a distribution of target weights and a distribution of perturbations from the target. The target weight is the adaptive goal of fetal development. In the simplest model, perinatal mortality is independent of variation in target weight and determined solely by the magnitude of the perturbation of birth weight from the target. In this model, mortality risk is concentrated in the tails of the birth weight distribution. A difference between populations in their distributions of target weights will be associated with a corresponding shift in their curves of weight-specific risk, without any difference between the populations in overall risk. In this model, risk would be reduced by decreasing the variance of the distribution of perturbations. The model is discussed in the context of the so-called "paradoxes of low birth weight."

    The birth of a premature baby is a stressful event for parents. The objective of this study was to determine early stress in parents of very low birth weight infants (VLBWIs) hospitalized in 12 neonatal intensive care units from a South American Neonatal Network, to identify associated factors, and to compare the level of parental stress in public versus private healthcare facilities. Cross-sectional study in mothers/fathers of VLBWIs (500 to 1500 g). Early parental stress was measured using the Parental Stressor Scale, with a score from 1 (low stress) to 5 (high stress). The sociodemographic characteristics of parents and newborn infants were collected and associated with levels of parental stress. The study included 273 fathers/mothers of a total of 218 VLBW preterm infants. The survey was administered at 5.9 ± 2.0 days of life. The average total parental stress was 3.1 ± 0.8, and the highest score was obtained for the parental role subscale (3.6). A lower education level, unemployment, not having held the newborn infant, and respiratory support requirement were associated with higher parental stress levels. Stress was higher among mothers than fathers, and at public facilities versus private ones. Among parents of VLBWIs, a moderate early parental stress was observed. Parental role alteration was the most relevant factor. Parental stress was higher among mothers and at public healthcare facilities. A greater sensitization, further research and interventions in this area are required.

The population representative Elementary School Children's Nutrition and Health Survey in Taiwan 2001-2002 and the national birth registry were used to examine school and social performance using the modified Scale for Assessing Emotional Disturbance questionnaires in relation to diet quality by the Youth Healthy Eating Index-Taiwan and birth weight of children aged 6-13 years (n=2283). Lower birth weight (≤15th percentile: ≤2850 g for boys and ≤2700 g for girls) children were mostly from mountainous areas and of indigenous descent. Compared to normal birth weight, lower birth weight girls experienced greater inability to learn and weaker overall competence. Better diet quality predicted more favorable emotional and behavioral outcomes in lower birth weight girls, and this persisted with adjustment for covariates. None of these findings were evident among boys. Girls' cognitive and social development appears to be susceptible to diet quality and birth weight, such that the adverse risk of lower birth weight on school performance may be offset by improved diet.

    Background and Objectives: LBW is the strongest factor related to prenatal, neonatal, postnatal and childhood mortality and morbidity. Air pollution is one of the risk factors that is recently gaining attention. This study was carried out to determine the relationship between the CO ambient and low birth weight in women referring to Tehran hospitals in 2007-2008.

     

    Methods: In this historical cohort study 225 pregnant women having lived within 5 kilometers of a monitoring station during pregnancy and referring to selected hospitals in Tehran were investigated. An information questionnaire was used for data collection and sampling was done by multistage sampling and convenience method. Women were assigned to low exposure group and high exposure group based on mean exposure to each pollutant during pregnancy. These two groups were matched with respect to confounding factors. SPSS software version 15, T statistics, c2, Man Withnney, and Relative Risk procedures were used for data analysis.

     

    Results: The result showed that 31.6% of CO high exposure group and 7.4% of CO low exposure group had Low birth weight baby. The result also showed a significant relationship between exposure to high amount of CO and LBW (p=0.001. Relative Risk calculated with confidence interval (RR=4/67, CI=(1/76-9/43 was found to be 95% and the amount of attributable risk was 66%.

     

    Conclusion: Based on these finding, exposure to carbon monoxide pollution can cause LBW. There should be an educational program about the disadvantages of CO pollutant on pregnant women living in densely populated areas of the city. Moreover, practical approaches should be provided to reduce these pollutants.

    We investigated whether the recommended phenobarbital loading dose of 15-20 mg/kg with maintenance of 3-4 mg/kg/day can safely be administered to very low birth weight preterm newborns with seizures. Twenty-four convulsive preterms of Phenobarbital was administered intravenously with a loading dose of 15 mg/kg in approximately 10-15 min. After 24 h, the maintenance dose of 3 mg/kg/day was administered as a single injection. Blood samples were obtained 2, 24, 48, 72, and 96 h after the phenobarbital loading dose was administered, immediately before the next phenobarbital dose was injected. None of the cases had plasma phenobarbital concentrations above the therapeutic upper limit of 40 μg/mL on the 2nd hour; one case (4.7%), on the 24th; 11 cases (45.8%), on the 48th; 15 cases (62.5%), on the 72nd; and 17 cases (70.8%), on the 96th hour. A negative correlation was detected between the serum concentrations of phenobarbital and gestational age on the 72th (p, 0.036; r, -0.608) and 96th hour (p, 0.043; r, -0.769). We suggest that particular attention should be done while administering phenobarbital in preterms, as blood levels of phenobarbital are higher than the reference ranges that those are often reached with the recommended doses in these groups of babies.

    To analyze survival and relevant morbidity by gestational age (GA) in very low birth weight (VLBW) infants (Neonatal Network (Red Neonatal Neocosur) between January 2001 and December 2011. Data on 8234 VLBW with a GA between 24+0 and 31+6 weeks were analyzed. Overall mortality was 26% (95% CI: 25.0-26.9), including 2.6% of deaths in the delivery room. Fact sheets for survival and morbidity for each week of gestation were developed based on collected data. Survival at discharge increased from 29% at 24 weeks of GA to 91% at 31 weeks of GA (p neonatal morbidity was inversely related to GA (p hemorrhage, and 4.6% periventricular leukomalacia. Among survivors, 47.3% had none of these five conditions. A tool for use in a clinical setting was developed based on updated regional data for establishing week-to-week survival and morbidity of newborn infants born between 24+0 and 31+6 weeks of GA. This information could be used to make decisions related to perinatal care and for counseling parents.

    Full Text Available Aim of study. The main prpose of present study was to determine the effect of endothelial dysfunction to the levels of markers of functional state of digestive system in infants with perinatal hypoxia. Materials and methods. The neuronal dysfunction was detected basing on the levels of NSE and NR2 antibodies. The functional state of gastrointestinal tract was estimated by IFABP, sLFABP, MUC-2, ITF, LBP. As the markers of endothelial dysfunction it was detected endotelin-1 and NO. The concentrations of markers were determined in peripheral blood of 66 preterm newborns exposure intrauterine hypoxia with 32–36 weeks of gestational age, which were classified as asphyxiated (1st group, n=30, non asphyxiated (2nd group, n=36 infants. Control group consisted of 22 healthy preterm babies. Results. It was not detected significant difference of NSE and NR2 antibodies levels between 1st and 2nd groups. The endothelin-1 concentrations significantly decreased in asphyxiated group in the background of high NO levels. The elevated level of IFABP in asphyxiated infants associated with compensative increasing of ITF and low anti endotoxine immunity. Conclusion. Endothelial dysfunction is one of the main factor resulting in hypoxic-ischemic injury of gastrointestinal tract in asphyxiated low birth weight infants.

    This study reports on the first observed case of a wild chimpanzee infant being snatched immediately after delivery and consequently cannibalized by an adult male in the Mahale Mountains, Tanzania. We demonstrate "maternity leave" from long-term data from the Mahale M group and suggest that it functions as a possible counterstrategy of mother chimpanzees against the risk of infanticide soon after delivery. The subjects of this study were the M group chimpanzees at Mahale Mountains, Tanzania. The case of cannibalism was observed on December 2, 2014. We used the long-term daily attendance record of the M group chimpanzees between 1990 and 2010 to calculate the lengths of "maternity leave," a perinatal period during which a mother chimpanzee tends to hide herself and gives birth alone. We observed a very rare case of delivery in a wild chimpanzee group. A female chimpanzee gave birth in front of other members, and an adult male snatched and cannibalized the newborn infant immediately after birth. Using the long-term data, we demonstrate that the length of "maternity leave" is longer than that of nonmaternity leave among adult and adolescent female chimpanzees. We argue that this cannibalism event immediately after birth occurred due to the complete lack of "maternity leave" of the mother chimpanzee of the victim, who might lack enough experience of delivery. We suggest that "maternity leave" taken by expecting mothers may function as a possible counterstrategy against infanticide soon after delivery. © 2017 Wiley Periodicals, Inc.

  20. Post-discharge body weight and neurodevelopmental outcomes among very low birth weight infants in Taiwan: A nationwide cohort study.

    Directory of Open Access Journals (Sweden)

    Chung-Ting Hsu

    Full Text Available Premature infants are at high risk for developmental delay and cognitive dysfunction. Besides medical conditions, growth restriction is regarded as an important risk factor for cognitive and neurodevelopmental dysfunction throughout childhood and adolescence and even into adulthood. In this study, we analyzed the relationship between post-discharge body weight and psychomotor development using a nationwide dataset.This was a nationwide cohort study conducted in Taiwan. Total of 1791 premature infants born between 2007 and 2011 with a birth weight of less than 1500 g were enrolled into this multi-center study. The data were obtained from the Taiwan Premature Infant Developmental Collaborative Study Group. The growth and neurodevelopmental evaluations were performed at corrected ages of 6, 12 and 24 months. Post-discharge failure to thrive was defined as a body weight below the 3rd percentile of the standard growth curve for Taiwanese children by the corrected age.The prevalence of failure to thrive was 15.8%, 16.9%, and 12.0% at corrected ages of 6, 12, and 24 months, respectively. At corrected ages of 24 months, 12.9% had low Mental Developmental Index (MDI scores (MDI<70, 17.8% had low Psychomotor Developmental Index (PDI scores (PDI<70, 12.7% had cerebral palsy, and 29.5% had neurodevelopmental impairment. Post-discharge failure to thrive was significantly associated with poor neurodevelopmental outcomes. After controlling for potential confounding factors (small for gestational age, extra-uterine growth retardation at discharge, cerebral palsy, gender, mild intraventricular hemorrhage, persistent pulmonary hypertension of newborn, respiratory distress syndrome, chronic lung disease, hemodynamic significant patent ductus arteriosus, necrotizing enterocolitis, surfactant use and indomethacin use, post-discharge failure to thrive remained a risk factor.This observational study observed the association between lower body weight at corrected age

    Full Text Available At birth, elevated IGF-I levels have been linked to birth weight extremes; high birth weight and low birth weight are risk factors for adult-onset chronic diseases including obesity, cardiovascular disease, and type 2 diabetes. We examined associations between plasma IGF-I levels and birth weight among infants born to African American and White obese and nonobese women. Prepregnancy weight and height were assessed among 251 pregnant women and anthropometric measurements of full term infants (≥37 weeks of gestation were taken at birth. Circulating IGF-I was measured by ELISA in umbilical cord blood plasma. Linear regression models were utilized to examine associations between birth weight and high IGF-I, using the bottom two tertiles as referents. Compared with infants with lower IGF-I levels (≤3rd tertile, those with higher IGF-I levels (>3rd tertile were 130 g heavier at birth, (β-coefficient=230, se=58.0, P=0.0001, after adjusting for gender, race/ethnicity, gestational age, delivery route, maternal BMI and smoking. Stratified analyses suggested that these associations are more pronounced in infants born to African American women and women with BMI ≥30 kg/m2; the cross product term for IGF-I and maternal BMI was statistically significant (P≤0.0004. Our findings suggest that the association between IGF-I levels and birth weight depends more on maternal obesity than African American race/ethnicity.

    Full Text Available OBJECTIVE: The Inuit population in Greenland has undergone rapid socioeconomic and nutritional changes simultaneously with an increasing prevalence of obesity. Therefore, the objective was to examine fetal programming as part of the aetiology of obesity among Inuit in Greenland by investigating the association between birth weight and measures of body composition and fat distribution in adulthood. METHODS: The study was based on cross-sectional data from a total of 1,473 adults aged 18-61 years in two population-based surveys conducted in Greenland between 1999-2001 and 2005-2010. Information on birth weight was collected from birth records. Adiposity was assessed by anthropometry, fat mass index (FMI, fat-free mass index (FFMI, and visceral (VAT and subcutaneous adipose tissue (SAT estimated by ultrasound. The associations to birth weight were analyzed using linear regression models and quadratic splines. Analyses were stratified by sex, and adjusted for age, birthplace, ancestry and family history of obesity. RESULTS: Spline analyses showed linear relations between birth weight and adult adiposity. In multiple regression analyses, birth weight was positively associated with BMI, waist circumference, FMI, FFMI and SAT with generally weaker associations among women compared to men. Birth weight was only associated with VAT after additional adjustment for waist circumference and appeared to be specific and inverse for men only. CONCLUSIONS: Higher birth weight among Inuit was associated with adiposity in adulthood. More studies are needed to explore a potential inverse association between birth size and VAT.

    Full Text Available Survival of extremely low birth weight (ELBW and extremely premature (EP infants has shown consistent improvement thanks to advances and innovations in perinatal and neonatal care. Regionalization, with high-risk deliveries in a tertiary perinatal center, offers the coordinated, collaborative, expert and specialized care needed by these mothers and their infants. Despite decreasing rates of the major neonatal morbidities observed in recent years, these continue still to be significant for ELBW/EP infants, impacting their overall prognosis. After NICU discharge and in the first years of life, issues with health, growth and development are common. In school age and adolescence, problems with behavior, socialization and cognition are prevalent. Adult outcomes of ELBW/EP need further clarity, emphasizing the importance for consistent long-term follow-up for this special cohort. Proceedings of the 10th International Workshop on Neonatology · Cagliari (Italy · October 22nd-25th, 2014 · The last ten years, the next ten years in Neonatology Guest Editors: Vassilios Fanos, Michele Mussap, Gavino Faa, Apostolos Papageorgiou

    To study growth hormone levels in IUGR and healthy controls and its association with birth weight and ponderal index. We studied 50 Intra uterine growth retarded (IUGR) and 50 healthy newborns born at term by vaginal delivery in JIPMER, Pondicherry, India. Cord blood was collected at the time of delivery for measurement of growth hormone. When compared with healthy newborns, IUGR newborns had higher growth hormone levels (mean +/- SD, 23.5 +/- 15.6 vs 16.2 +/- 7.61 ngm/ml, P = 0.019). A negative correlation was identified between growth hormone levels and birth weight (r2 = - 0.22, P = 0.03) and ponderal index (r2 = - 0.36, P = 0.008). Correlation of growth hormone levels was much more confident with ponderal index than with birth weight. At birth IUGR infants display increased growth hormone levels which correlate with ponderal index much more confidently than with birth weight.

  7. Establishing partnership with traditional birth attendants for improved maternal and newborn health: a review of factors influencing implementation.

    Miller, Tina; Smith, Helen

    2017-10-19

    Recent World Health Organization recommendations recognize the important role Traditional Birth Attendants (TBAs) can play in supporting the health of women and newborns. This paper provides an analysis of key factors that affect the implementation of interventions to develop partnerships with TBAs to promote improved access to skilled care at birth. We conducted a secondary analysis of 20 papers identified through two systematic reviews that examined the effectiveness of interventions to find new roles for TBAs on maternal and newborn health outcomes, as well as papers identified through a systematic mapping of the maternal health literature. The Supporting the Use of Research Evidence framework (SURE) guided the thematic analysis to explore the perceptions of various stakeholders and implementation barriers and facilitators, as well as other contextual issues. This analysis identified countries that have implemented interventions to support the transition from birth with a TBA to birth with a skilled birth attendant. Drawing on the experiences of these countries, the analysis highlights factors that are important to consider when designing and implementing such interventions. Barriers to implementation included resistance to change in more traditional communities, negative attitudes between TBAs and skilled attendants and TBAs concerns about the financial implications of assuming new roles. Facilitating factors included stakeholder involvement in devising and implementing interventions, knowledge sharing between TBAs and skilled birth attendants, and formalised roles and responsibilities and remuneration for TBAs. The implementation barriers identified in this analysis could, if not addressed, prevent or discourage TBAs from carrying out newly defined roles supporting women in pregnancy and childbirth and linking them to the formal health system. This paper also identifies the factors that seem critical to success, which new programmes could consider adopting

    Provision of essential newborn care (ENC) can save many newborn lives in poor resource settings but coverage is far from universal and varies by country and place of delivery. Understanding gaps in current coverage and where coverage is good, in different contexts and places of delivery, could make a valuable contribution to the future design of interventions to reduce neonatal mortality. We sought to describe the coverage of essential newborn care practices for births in institutions, at home with a skilled birth attendant, and at home without a skilled birth attendant (SBA) in rural areas of Bangladesh, Nepal, and India. We used data from the control arms of four cluster randomised controlled trials in Bangladesh, Eastern India and from Makwanpur and Dhanusha districts in Nepal, covering periods from 2001 to 2011. We used these data to identify essential newborn care practices as defined by the World Health Organization. Each birth was allocated to one of three delivery types: home birth without an SBA, home birth with an SBA, or institutional delivery. For each study, we calculated the observed proportion of births that received each care practice by delivery type with 95% confidence intervals, adjusted for clustering and, where appropriate, stratification. After exclusions, we analysed data for 8939 births from Eastern India, 27 553 births from Bangladesh, 6765 births from Makwanpur and 15 344 births from Dhanusha. Across all study areas, coverage of essential newborn care practices was highest in institutional deliveries, and lowest in home non-SBA deliveries. However, institutional deliveries did not provide universal coverage of the recommended practices, with relatively low coverage (20%-70%) across all study areas for immediate breastfeeding and thermal care.

    BACKGROUND: Birth weight is an early correlate of disease later in life, and animal studies suggest that low birth weight is associated with reduced activity and increased sedentary time. Whether birth weight predicts later sedentary time in humans is uncertain. OBJECTIVES: We examined the relation...... between birth weight and sedentary time in youth and examined whether this association was mediated by central adiposity. DESIGN: We used pooled cross-sectional data from 8 observational studies conducted between 1997 and 2007 that consisted of 10,793 youth (boys: 47%) aged 6-18 y from the International...... Children's Accelerometry Database. Birth weight was measured in hospitals or maternally reported, sedentary time was assessed by using accelerometry (
