Objective: to estimate the prevalence and verify the factors associated with low birth weight in full-term newborns. Methods: this is a retrospective study conducted with 24,744 newborns. Data were retrieved from the Sistema de Informação sobre Nascidos Vivos (Information System on Live Births). For the analysis, multiple logistic regression was used using the hierarchical model with maternal, gestational, and care variables. Results: the prevalence of low birth weight was 2.4%, with 51.0% of cases in male newborns, 73.7% in women aged 20-34 years; 56.5% were multiparous and 95.0% had eight years of education or more. In the multiple analysis, the association of low weight with the number of prenatal consultations, newborn’s birth order, and sex were observed. Conclusion: the factors associated with low birth weight in full-term newborns were male sex, multiparity, and less than seven prenatal consultations.

The frequency of sex chromatin-positive nuclei during the first 7 days of life was determined in oral mucosa smears stained with lactic acetic orcein in three groups of newborn female infants: 28 cases of full-term newborns, 17 cases of infants with low birth weight (less than 2,000 gm) and high gestational age (more than 32 weeks), and 11 cases of infants with low birth weight and low gestational age (32 weeks or less). A transient suppression of sex chromatin frequency was observed for the first 3 days of life in the full-term females, as has been reported by previous workers. The infants with low birth weight and high gestational age likewise showed transient suppression. The infants with low birth weight and low gestational age, on the other hand, exhibited no comparable suppression of sex chromatin. The findings suggest that the mechanism responsible for sex chromatin suppression is related to a physiologic process that develops in the last 8 weeks of gestation.

ABSTRACT This was a cross-sectional study that investigated maternal and child factors associated with neonatal mortality. Data was obtained from the Live Births and Mortality Information Systems integrated by linkage. A total of 9,349 live births and 78 deaths in the neonatal period, which occurred in 2010 in Cuiabá-MT were analyzed. Univariate and multivariate analyzes were performed. In the multiple logistic regression, neonatal mortality was associated with: maternal age less than 20 years; prematurity; low birth weight; Apgar score less than seven at 1 and 5 minutes; and presence of congenital anomaly. The results highlight the need to improve the quality of prenatal care in order to prevent low birth weight and prematurity. The association between neonatal death and low Apgar score at 1 and 5 minutes indicates the importance of investments in delivery care.

Low Birth Weight (LBW) is the proportion of live births weighing less than 2,500 grams and 20 times the chance of dying in infancy. LBW is the result of premature birth (<37 weeks' gestation) or impaired intrauterine growth. Neonatal mortality is one of the indicators determining the health and welfare of children. IMR in Banjarnegara Regency in 2015 was 13.23 per 1,000 live births which in absolute terms still ranked highest in Central Java Province. The formulation of the problem is risk factors of low birth weight  at Karang Kobar Health Center in Banjarnegara Regency in 2018. This research is a descriptive analytic study using case control study design. The research sample was taken from the total number of LBW in January to December 2017. Data were analyzed univariate and bivariate. The results of the study, the factors associated with the incidence of LBW are the factors of maternal age during pregnancy, gestational age, anemia, and nutrition pregnant women.

Estimate Fetal Weight

Introduction: the aim of this trial was to estimate fetal weight by clinical and ultrasound methods and to compare with the weight at birth in full-term newborns. Methods: This is an epidemiological, observational, cross-sectional study of a cohort of healthy full-term newborns. The sample size was 102 neonates born at the Pablo Arturo Suarez Hospital, in Quito, Ecuador, from November 2019 to January 2020. Results: In full-term neonates, the estimate on ultrasound was 80.00%, while in the clinical assessment was 72.29%. The profile of newborn analyzed is man, mestizo, Ecuadorian, born in the highlands region, with a mean gestational age of 38.67 weeks and a mean birth weight of 3,023 grams, in whom it estimated the fetal weight through ultrasound and clinical assessment. The estimation of the absolute error in both methods analyzed was 2.43% to ultrasound and -4.65% to clinical assessment, and both showed moderate concordance, 78.2% to ultrasound, and 85.6% to clinical assessment. Multivariate analysis showed the neonates with modified weight by ultrasound are 13.44 times more likely to show altered weight at birth, while neonates with modified weight by the clinical assessment are 11.95 times more likely to show altered weight at birth. Conclusions: Accuracy in the clinical assessment was always higher than in the ultrasound method, especially in low weight newborns.

CONTEXT AND OBJECTIVE: There are no studies on birth weights among full-term infants born by means of elective cesarean section. We aimed to study this in private and public hospitals. DESIGN AND SETTING: Retrospective study at Universidade Federal do Triângulo Mineiro, Uberaba, Brazil. METHODS: Data were collected from the municipal medical birth register of Uberaba from January to December 2000. The data obtained (maternal age, type of delivery, number of prenatal care visits and birth weight, from full-term pregnancy) from the university hospital (UH), which is a tertiary hospital that only attends patients within the National Health System (SUS), were compared with data from four private hospitals (PHs) that attend health insurance plans and private patients. Student's t test, chi2 test and multiple logistic regression were used for statistical analysis, with the significance level set at p < 0.05. RESULTS: In the PHs, 1,100 out of 1,354 births (81.2%) were by cesarean section and in the UH, 373 out of 1,332 (28%). Birth weight increased significantly in association with increasing numbers of prenatal care visits, except for cesarean section cases in PHs. Birth weights among vaginal delivery cases in PHs were greater than in the UH (p < 0.05), but this was not observed among cesarean section cases. Multiple logistic regression showed that there was greater risk of low birth weight in PHs (odds ratio: 2.33; 95% confidence interval: 1.19 to 4.55). CONCLUSION: Elective cesarean section performed in PHs may be associated with low birth weight among full-term infants.
