Protective factors for early initiation of breastfeeding among Brazilian nursing mothers.

Objectives: Evaluate the protective factors associated with early initiation of breastfeeding. Methods: Cross-sectional study conducted with Brazilian nursing mothers. Breastfeeding in the first hour of life and difficulty initiating breastfeeding in the birth room were adopted as outcome variables and associated with other maternal and child information. Poisson regression was conducted to synthesize the data. Results: Among 104 nursing mothers evaluated, 56.7% reported breastfeeding in the first hour of life and 43% had difficulty initiating breastfeeding in the birth room. There was a higher prevalence of breastfeeding in the first hour of life among mothers with previous breastfeeding experience (PR = 1.47, 95% CI 1.04-2.07). Difficulty initiating breastfeeding in the birth room was more prevalent among mothers who did not receive breastfeeding guidance during antenatal care (PR = 2.83, 95% CI 1.43-4.32) and those without previous breastfeeding experience (PR = 2.49, 95% CI 1.24-6.45). Conclusion: These findings highlight the importance of adequate professional guidance, especially for primiparous mothers.

Effect of Ultra-Processed Foods Consumption and Some Lifestyle Factors during Pregnancy on Baby's Anthropometric Measurements at Birth.

OBJECTIVE: This study aimed to assess the association between ultra-processed foods (UPF) consumption and some lifestyle factors during pregnancy and the baby's anthropometric measurements at birth. METHODS: Cross-sectional study conducted with immediate postpartum women and their babies. Food consumption during pregnancy was assessed retrospectively by a semi-quantitative food frequency questionnaire, and the baby's anthropometric measurements were obtained from the medical records. The percentual of energy from UPF was estimated, categorized in tertiles, and associated with the baby's anthropometric measurements using multinomial logistic regression, adjusting by maternal characteristics (per capita income, maternal age, gestational weight gain, parity, physical activity, and number of prenatal consultations). RESULTS: A total of 626 immediate postpartum women and their babies were evaluated. The mean percentual of energy from UPF consumption during pregnancy was 30.56%. Before adjustment, there was a greater chance of insufficient birth weight among babies of immediate postpartum women in the highest tertile of UPF consumption (OR 1.72; 95% CI 1.09-2.70; p = 0.020); however, such an association was not significant in the adjusted analyses. CONCLUSIONS: No association between UPF consumption during pregnancy and baby's anthropometric measurements at birth was observed, probably due to the multifactorial nature of anthropometry and the interference of sociodemographic, gestational, and environmental factors in the baby's health outcomes.

The Influence of Nutrients Intake during Pregnancy on Baby's Birth Weight: A Systematic Review.

BACKGROUND AND OBJECTIVE: Maternal food intake during pregnancy can substantially interfere in the baby's anthropometric measurements at birth. Our objective was to perform a systematic review that investigate the influence of nutrient intake via food during pregnancy on the baby's anthropometric measurements at birth. METHODS: A search was performed without time limits on CINAHL, Embase, PubMed, Scopus and Web of Science databases and manual on studies references. All nutrients and baby's anthropometric measurements at birth were included as descriptors. RESULTS: Thirty articles were included, the majority of prospective cohort studies, with 15.39 (2.36) quality points (maximum value: 22). Thirty-six results of associations were found, of which 17 studies had direct associations between nutrient intake and birth outcomes. Inverse associations were identified in 8 studies and 11 articles showed no significant associations in all analyses. Maternal food intake of vitamin C, calcium and magnesium during pregnancy seems to have a positive influence on the baby's birth weight, while carbohydrates intake have an inverse association with the same outcome. CONCLUSION: It is suggested that vitamin C, calcium, magnesium and carbohydrates influence on baby's birth weight. So, these specific nutrients need more attention to the consumption, in addition to carried out new studies, with robust methodologies for measuring maternal food consumption and considering the several factors that can interfere in this assessment. REGISTRATION: This review has been registered to the PROSPERO (International prospective register of systematic reviews) (ID: CRD42020167889).

Influence of ultra-processed foods consumption during pregnancy on baby's anthropometric measurements, from birth to the first year of life: a systematic review / Influência do consumo de alimentos ultraprocessados durante a gestação nas medidas antropométricas do bebê, do nascimento ao primeiro ano de vida: uma revisão sistemática

Abstract Objectives: to perform a systematic review of studies that investigated the influence of ultra-processed foods (UPF) consumption during pregnancy on child's anthropometric parameters up to one year of life. Methods: cohort and cross-sectional studies were researched in BVS, Cinahl, Cochrane, Embase, Pubmed, Scopus and Web of Science databases until March 2020, and the main descriptors were: "Pregnant Women", "Ultra-processed foods", "Birth Weight", "Smallfor Gestational Age", "Infant", "Newborn". Results: seventeen articles were considered eligible and evaluated the associations between the exposures: ultra-processed dietary patterns; soft drinks, sugar-sweetened beverages, artificially sweetened beverages; fast food, junk food, sweets, snacks and the outcomes: birth weight and its classifications; length and head circumference at birth; birth weight adjustments according to gestational age; weight/age, length/age, body mass index/age and weight/length indices. The results showed: 36 non-significant associations between the exposures and the outcomes; 13 direct associations (outcomes versus ultraprocessed dietary patterns, soft drinks, artificially sweetened beverages, sweets, junk food) and 5 inverse associations (outcomes versus ultra-processed dietary patterns, soft drinks). Conclusions: most of the evaluated literature did not demonstrate the influence of UPF consumption during pregnancy on the newborn's anthropometric measurements up to one year of life and denoted a smaller number of direct and inverse associations between the exposures and the outcomes.

Resumo Objetivos: realizar uma revisão sistemática de estudos que investigaram a influência do consumo de alimentos ultraprocessados (AUP) na gestação nas medidas antropométricas do recém-nascido até um ano de idade. Métodos: foram pesquisados estudos de coorte e transversais nas bases BVS, Cinahl, Cochrane, Embase, Pubmed, Scopus e Web of Science até março de 2020, tendo como principais descritores: "Pregnant women", "Ultra-processed foods", "Birth weight", "Small for Gestational Age", "Infant", "Newborn". Resultados: dezessete artigos foram considerados elegíveis e avaliaram as associações entre as exposições: padrões alimentares ultraprocessados; refrigerantes, sugar-sweetened beverages ou artificially sweetened beverages; fastfood, junkfood, doces e snacks e os desfe-chos:peso ao nascer e suas classificações; comprimento e perímetro cefálico ao nascimento; adequações do peso ao nascer segundo idade gestacional; e índices peso/idade, compri-mento/idade, índice de massa corporal/idade e peso/comprimento. Foram encontradas: 36 associações nulas entre exposições e desfechos avaliados; 13 diretas (desfechos versus padrões alimentares ultraprocessados, refrigerantes, artificially sweetened beverages, doces e junkfood) e 5 inversas (desfechos versus padrões alimentares ultraprocessados e refrigerantes). Conclusões: a maioria da literatura avaliada não demonstrou influência do consumo de AUP na gestação nas medidas antropométricas do recém-nascido até um ano de vida e apontou um menor número de associações diretas e inversas entre as exposições e os desfechos analisados.

Use of Artificial Nipples Among Brazilian Infants and Associated Factors.

Transversal study conducted in a Human Milk Bank to evaluate the factors associated with the use of artificial nipples (pacifier and/or nursing bottle) among Brazilian infants. Analyses were performed using the χ2 test and logistic regression analysis. A total of 6017 nursing mothers were evaluated and the use of artificial nipples was reported by 31.3%. The chance of using artificial nipples was higher among infants whose mothers attended antenatal care in private hospitals [odds ratio (OR): 1.61, 95% confidence interval (CI) 1.21-2.14], born in maternities without the Baby-Friendly Hospital Initiative (BFHI) (OR: 18.38, 95% CI 13.50-25.04) and those with adequate birth weight (OR: 2.83, 95% CI 1.99-4.03). A lower chance of using artificial nipples was observed among infants whose mothers had previous breastfeeding experience (OR: 0.76, 95% CI 0.61-0.95), received guidance on breastfeeding during antenatal care (OR: 0.80, 95% CI 0.65-0.98), practiced exclusive breastfeeding (OR: 0.36, 95% CI 0.28-0.45), breastfeeding on demand (OR: 0.66, 95% CI 0.52-0.85) and residents of inland cities/towns (OR: 0.38, 95% CI 0.20-0.72). The findings highlight the importance of breastfeeding guidance during antenatal care and the role of BFHI in clarifying risks associated with artificial nipple use.

[Healthcare and gestational factors associated with anemia in nursing mothers attended in a human milk bank]. / Fatores assistenciais e gestacionais associados à anemia em nutrizes atendidas em um banco de leite humano.

Anemia is a public health problem that affects about 30% of Brazilian women, which may cause deleterious effects on the health and quality of life of mother and child. This article seeks to evaluate the healthcare and gestational factors associated with anemia among mothers receiving care at a human milk bank (HMB) of reference. It is a cross-sectional study with secondary data about sociodemographic and pregnancy information on 12283 nursing mothers from 2009 to 2012. The Kolmogorov-Smirnov and chi-square or Fisher's exact tests were applied. The prevalence ratios (PR) and their 95% confidence intervals were estimated by Poisson regression with robust variance. Anemia was identified in 29.2% of the sample and the prevalence was higher among mothers who did not have prenatal appointments (PR = 3.84; 95% CI 3.26 to 4.54); those who made 3 or less antenatal visits (PR = 1.92; 95% CI 1.21 to 3.06) and those who have had multiple pregnancies (OR = 2.29, 95% CI 1.25 to 4.19). The results showed a higher prevalence of anemia among women who did not have the appropriate prenatal care and who have had multiple pregnancies, highlighting the importance of healthcare as a factor in the prevention of anemia and other complications during pregnancy.

A anemia é um problema de saúde pública que acomete cerca de 30% das gestantes brasileiras, podendo acarretar efeitos deletérios à saúde e qualidade de vida do binômio mãe-filho. O objetivo deste artigo é avaliar os fatores assistenciais e gestacionais associados à anemia entre nutrizes atendidas em um banco de leite humano (BLH) de referência. Estudo transversal com dados secundários referentes a informações sociodemográficas e gestacionais de 12283 nutrizes no período de 2009 a 2012. Aplicaram-se os testes Kolmogorov-Smirnov e Qui-quadrado ou exato de Fisher. Estimaram-se as Razões de Prevalência (RP) e respectivos Intervalos de Confiança-IC95%, por meio da Regressão de Poisson com variância robusta. Identificou-se a prevalência de anemia em 29,2% da amostra, sendo maior entre as mães que não realizaram o pré-natal (RP = 3,84; IC95% 3,26-4,54); as que realizaram até 3 consultas pré-natais (RP = 1,92; IC95% 1,21-3,06) e aquelas que tiveram gestação múltipla (RP = 2,29; IC95% 1,25-4,19). Os resultados apontaram maior prevalência de anemia entre as mulheres que não realizaram o pré-natal apropriado e as que tiveram gestações múltiplas, destacando-se a importância da assistência à saúde como fator de prevenção à anemia e demais intercorrências gestacionais.
