ObjectiveTo investigate the association between maternal anemia and low/insufficient birth weight.DesignA prospective cohort study of pregnant women who underwent prenatal care at the healthcare units in a municipality of northeast Brazil together with their newborn infants was carried out. The pregnant women were classified as having anemia when the hemoglobin level was below 11 g/dl. Infants who were born full term weighing less than 2500 grams were classified as low birth weight, and those weighing between 2500 and 2999 grams were classified as insufficient weight. The occurrence of maternal anemia and its association with birth weight was verified using crude and adjusted Relative Risk (RR) estimates with their corresponding 95% confidence intervals (95%CIs).ResultsThe final sample was comprised of 622 women. Maternal anemia was considered a risk factor for low/insufficient birth weight, after adjusting the effect measurement for maternal age, family income, urinary infection, parity, alcoholic beverage consumption during pregnancy and gestational body mass index: RRadjusted = 1.38 [95% CI: 1.07 to 1.77].ConclusionsMaternal anemia was associated with low/insufficient birth weight, representing a risk factor for the gestational outcomes studied.

Background The oropharyngeal colostrum administration protocol to treat premature newborns is a possible and plausible strategy in neonatal health services, since the immunoprotective components of colostrum can be absorbed by the lymphoid tissues of the oropharynx. In this context, this study aims to describe the implementation of oropharyngeal colostrum immunotherapy in very low birth weight preterm newborns in a neonatal unit, as well as to test an algorithm in a public hospital. Methods The protocol is applied in a non-randomized, superiority clinical trial with historical control. In the treatment group, 0.2 mL of raw colostrum is dripped into the right and left oropharyngeal mucosa, totaling 8 administrations every 24 h until the 7th complete day of life interruptedly. The control group consists of very low birth weight preterm newborns born in the same hospital in previous years (historical control). The clinical progression of 60 newborns until hospital discharge is recorded on standardized forms. A total of 350 participants are estimated to complete the survey in 4 years. The occurrence of continuous outcomes between the groups are compared through the paired t-test or Wilcoxon’s two-sample test. The chi-square test or Fisher’s exact test, and survival analysis are used for binary outcomes. The nutritional status is assessed through Intergrowth-21st growth curves for preterm newborns. Discussion The flows of the protocol’s actions is sorted by an algorithm, compatible with the Brazilian reality of a public hospital. This measure facilitates and systematizes clinical care, organizes the team’s work process, speeds up the intervention steps, standardizes decision-making and unifies the quality of care, besides showing the feasibility of oropharyngeal colostrum immunotherapy.

Background Little is known about the factors associated with the World Health Organization (WHO) recommendation of breastfeeding for at least 2 years. The objective of this study was to identify risk factors for and protective factors against breastfeeding interruption before 2 years of age. Methods In this live birth cohort, mother and infant dyads were followed for 2 years. Data collection was performed at the maternity ward and subsequently at the children’s homes, monthly during the first 6 months of life and then at 9, 12, 18, and 24 months. The outcome of interest was breastfeeding interruption before 2 years of age. Median duration of breastfeeding was estimated using Kaplan-Meier’s survival analysis, and the associations were tested using Cox’s hierarchical multivariate model. Significance was set at 5%. Results Data from a total of 1344 dyads were assessed. Median breastfeeding duration was 385 days. The following risk factors for breastfeeding interruption were identified: white skin color (adjusted hazard ratio [HRa]: 1.31; 95% confidence interval [95%CI]: 1.10–1.56), primiparity (HRa: 1.21; 95%CI: 1.05–1.40), working outside the home (HRa: 1.52; 95%CI: 1.30–1.77), child sex male (HRa: 1.18; 95%CI: 1.03–1.35) and use of a pacifier (HRa: 3.46; 95%CI: 2.98–4.01). Conversely, the following protective factors were identified: lower family income (HRa: 0.81; 95%CI: 0.71–0.94), mother-infant bed-sharing (HRa:0.61, 95%CI: 0.52–0.73), on-demand breastfeeding in the first month (HRa: 0.64; 95%CI: 0.47–0.89) and exclusive breastfeeding at 4 months (HRa: 0.58, 95%CI: 0.48–0.70). Conclusions The findings allowed to identify both risk factors for and protective factors against breastfeeding interruption before 2 years of age. Knowledge of these factors may help prevent this event and aid in the development of programs that help women maintain breastfeeding for at least 2 years, as recommended by the WHO.

Objetivo: Caracterizar os nascidos vivos prematuros em um município do nordeste brasileiro quanto às características demográficas, clínicas, necessidade de reanimação e hospitalização. Métodos: Estudo descritivo, realizado em dois hospitais da Bahia, com a participação de 333 nascidos vivos prematuros. Os dados foram coletados no período de abril de 2014 a fevereiro de 2016, tabulados e analisados SPSS versão 22.0. Foi aprovado por Comitê de Ética. Resultados: os nascidos vivos prematuros foram em sua maioria do sexo masculino, com baixo peso ao nascer, Apgar média de 7 no primeiro e 8 no quinto minuto de vida. A maioria foi classificado como prematuro tardio por meio da DUM, ecografia e método de Capurro. Referente a assistência imediata no nascimento, 60,5% dos recém-nascidos foram reanimados. Conclusão: Apontam a necessidade de capacitação dos trabalhadores da saúde em cuidados clínicos avançados e o planejamento de medidas eficazes que visem reduzir complicações ao nascimento.
