PURPOSE: To analyze the breastfeeding self-efficacy in mothers of premature and full-term newborns, in the period of 180 days, and to know the social and obstetric factors that influence the practice of maintaining the exclusive breastfeeding in the period of exclusive recommendation. METHODS: Cohort with 44 mothers admitted to a public maternity hospital between January and October 2018. The mothers were divided into two groups: Premature and Full-term Groups. The Breastfeeding Self-efficacy Scale was applied in the immediate postpartum period, in addition to a questionnaire elaborated by the authors to collect sociodemographic and obstetric variables. The follow-up was done on the 30th, 120th and 180th days of the newborn's life, by telephone. For the statistical analysis between the groups, the Statistical Package for the Social Sciences (SPSS) was used. RESULTS: There was no difference in the self-efficacy score, nor in the obstetric and socioeconomic characteristics between the groups, except for family income (lower in the Premature Group - p = 0.031). The diet type was different on the 30th day after delivery (p = 0.023), with greater adherence to the exclusive breastfeeding in the Premature Group. No association was found between breastfeeding self-efficacy and exclusive breastfeeding practice in the 180-day period. CONCLUSION: In this sample, the breastfeeding self-efficacy was not related to the exclusive breastfeeding practice in the period of 180 days, in both groups. The premature group showed lower family income and greater adherence to exclusive breastfeeding on the 30th day postpartum.
OBJETIVO: Analisar a autoeficácia da amamentação, no período de 180 dias, em mães de recém-nascidos prematuros e a termo, e conhecer os fatores que influenciam na prática do aleitamento materno exclusivo no período de recomendação exclusiva. MÉTODO: Coorte realizado com 44 puérperas de uma maternidade pública, entre janeiro e outubro de 2018. As puérperas foram divididas em dois grupos: Grupo Prematuro e Grupo Termo. A Breastfeeding Self-efficacy Scale foi aplicada no pós-parto imediato, além de um questionário elaborado pelos autores para coleta de variáveis sociodemográficas e obstétricas. O monitoramento da continuidade do aleitamento materno foi feito no 30º, 120º e 180º dia de vida do neonato, via telefone. Para a análise estatística entre os grupos foi utilizado o Statistical Package for the Social Sciences (SPSS). RESULTADOS: Não houve diferença na pontuação da autoeficácia, nas características obstétricas e socioeconômicas entre os grupos, exceto para a variável renda familiar, (menor no Grupo Prematuro - p=0,031). O tipo de dieta foi diferente no 30º dia pós parto (p=0,023), com maior adesão ao aleitamento materno exclusivo no Grupo Prematuro. Não foi encontrada associação entre a autoeficácia da amamentação e a prática do aleitamento materno exclusivo no período de 180 dias. CONCLUSÃO: Nesta amostra, a autoeficácia da amamentação não teve relação com a prática do aleitamento materno exclusivo no período de 180 dias em ambos os grupos. O grupo de prematuros apresentou menor renda familiar e maior adesão ao aleitamento materno exclusivo no 30º dia pós parto.

Vitamin E deficiency (VED) is associated with clinical repercussions in preterm newborns (PTN), but low levels are also found in full-term newborns (TN). As this inadequacy can compromise neurogenesis in childhood, studies are needed to assess whether there is a difference in vitamin E status among newborns according to gestational age to provide support for neonatal monitoring protocols. This systematic review presents a synthesis of the available information on the vitamin E status among PTN and TN. The review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Observational studies that evaluated alpha-tocopherol levels were searched in the databases reported in the protocol registered in PROSPERO (CRD42021165152). The Newcastle-Ottawa Scale was used to assess the methodological quality. Overall, 1809 articles were retrieved; 10 were included in the systematic review. In the PTN, the alpha-tocopherol levels ranged from 3.9 to 8.5 mmol/L, while in TN, they were 4.9 to 14.9 mmol/L, and VED ranged from 19% to 100% in newborns. Despite substantial heterogeneity in research methodology and VED classification, the results suggest that the alpha-tocopherol levels among preterm and full-term newborns is below the recommended levels. Our findings demonstrate that further investigations are needed to standardize this classification and to monitor vitamin E status in birth and postnatal with adequate bias control.

Background and Aims: Changes in eating patterns have been leading to an increase in the consumption of ultra-processed foods (UPF), negatively impacting the quality of the diet and generating risk of harm to the health of the adult population, however, there is no systematized evidence of the impact of UPF in maternal-child health. Thus, in this study we aimed to evaluated the association between UPF consumption and health outcomes in the maternal-child population. Methods: Systematic review registered on the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42021236633), conducted according to the PRISMA diagram in the following databases: PubMed, Medline, Scopus, Web of Science, Scielo, and CAPES thesis and dissertation directory. We included original cross-sectional, case-control and cohort studies in any language. Eligibility criteria were (a) food consumption assessment by the NOVA classification, (b) health outcome (nutritional or diseases), and (c) maternal-child population (pregnant, lactating women and infants/children). All data were analyzed and extracted to a spreadsheet structured by two independent reviewers. We evaluated the methodological quality of the studies included using the Newcastle-Otawa Scale and RoB 2. Results: Searches retrieved 7,801 studies and 15 contemplated the eligibility criteria. Most studies included were cohort studies (n = 8, 53%), had children as their population (n = 9, 60%) and only one study evaluated UPF consumption in infants and lactating women. Panoramically, we observed that a higher participation of UPF in children's diet has been associated with different maternal-child outcomes, such as increase of weight gain, adiposity measures, overweight, early weaning, lower diet quality, metabolic alterations, diseases, and consumption of plastic originated from packaging. Only one of the studies included did not present high methodological quality. Conclusion: Despite the limited literature on UPF consumption and health outcomes in the maternal-child population, the highest UPF consumption negatively impacted nutrition and disease development indicators in pregnant, lactating women and children. Considering the expressive participation of these foods in the diet, other studies should be conducted to further investigate the impact of UPF consumption on different health indicators, especially in the lactation phase for this was the one to present the most important knowledge gap.

RESUMO Objetivo Avaliar o estado nutricional em vitamina A de puérperas adolescentes e adultas em relação à ingestão alimentar, retinol no soro e colostro e o suprimento desta vitamina para o recém-nascido. Métodos Estudo transversal, incluindo 136 puérperas, sendo 68 adolescentes e 68 adultas, atendidas em uma maternidade pública. A ingestão dietética de vitamina A foi estimada por um questionário de frequência do consumo alimentar. Foram coletados sangue e colostro em condição de jejum para análise dos níveis de retinol. As amostras foram analisadas por cromatografia líquida de alta eficiência. A estimativa da ingestão de vitamina A pelo recém-nascido foi calculada pelo volume ingerido de leite e a média da concentração de retinol no colostro materno. Resultados A estimativa de consumo foi 681,2±535 µgRAE/dia, para as adolescentes, e 891,8±831,5 µgRAE/dia, para as adultas (p>0,05). As médias de retinol sérico foram 40,6±9,7 µg/dL, no grupo das adolescentes, e 44,9±10,9 µg/dL, no das adultas (p<0,05). No colostro, as adolescentes apresentaram concentração de retinol de 83,1±26,5 µg/dL e as adultas de 81,8±29,8 µg/dL (p>0,05). O volume médio ingerido pelos lactentes provenientes de puérperas adolescentes foi de 435,1+140,7 µgRAE/dia e de 409,7+150,8 µgRAE/dia pelos recém-nascidos das adultas. Na análise individual, 42,6% (n=29) das adolescentes e 52,9% (n=36) das mães adultas não supriram adequadamente a recomendação diária do lactente. Conclusão As adolescentes apresentaram ingestão inadequada de vitamina A. Ambos os grupos apresentaram percentuais de inadequação no soro e colostro e, consequentemente, no fornecimento da vitamina A aos recém-nascidos.
ABSTRACT Objective To assess the vitamin A status of puerperal adolescents and adults in relation to food intake, serum and colostrum retinol, and the supply of this vitamin to the newborn. Methods Dietary vitamin A intake was investigated by a food frequency questionnaire. Fasting blood and colostrum samples were collected for retinol quantification by high-performance liquid chromatography. Newborn vitamin A intake was given by multiplying milk intake by the mean colostrum retinol level. Results This cross-sectional study included 136 puerperal women (68 adolescents and 68 adults) seen at a public maternity hospital. The estimated dietary intake was 681.2±535 µgRAE/day for adolescents and 891.8±831.5 µgRAE/day for adults (p>0.05). The mean serum retinol levels were 40.6±9.7 µg/dL in adolescents and 44.9±10.9 µg/dL in adults (p<0.05). The mean colostrum retinol levels in adolescents and adults were 83.1±26.5 µg/dL and 81.8±29.8 µg/dL, respectively (p>0.05). The adolescents' newborns had a mean retinol intake of 435.1±140.7 µgRAE/day, and the adults' newborns had a mean retinol intake of 409.7 ± 150.8 µgRAE/day. Twenty-nine (42.6%) adolescents and thirty-six (52.9%) adults did not supply enough vitamin A per day to their newborns. Conclusion Adolescents had inadequate vitamin A intake. Adolescents and adults had similar prevalences of inadequate serum retinol. Some adolescents and adults had inadequate colostrum retinol levels, resulting in low retinol intake by their newborns.
