SBP participa de reunião com Ministério da Saúde para debater promoção da NBCAL

Representantes da Sociedade Brasileira de Pediatria (SBP) participaram de reunião, convocada pelo Ministério da Saúde, para debater a promoção do aleitamento materno no País, em especial o cumprimento da Norma Brasileira de Comercialização de Alimentos para Lactentes e Crianças de Primeira Infância, Bicos, Chupetas e Mamadeiras (NBCAL).

Episódio 1 - Semana Mundial de Aleitamento Materno (SMAM) - A legislação a favor da mulher trabalhadora que amamenta

Este episódio será dividido em duas partes e trará como tema a Semana Mundial de Aleitamento Materno (a SMAM). Ela é lembrada todos os anos entre 1º a 7 de agosto em mais de 170 países, sendo uma importante estratégia de promoção da amamentação, alinhada aos objetivos para o Desenvolvimento Sustentável da Organização Mundial de Saúde. No Brasil, desde 2017, o apoio à amamentação não se promove apenas durante a SMAM, e sim durante todo o mês de agosto, conhecido como Agosto Dourado, devido à cor que simbolizam padrão ouro de qualidade do leite humano.

Episódio 2 - Semana Mundial de Aleitamento Materno (SMAM) - Como as pessoas podem apoiar e a atuação do BLH do IFF/Fiocruz

A Semana Mundial de Aleitamento Materno (SMAM), celebrada de 1 a 7 de agosto, coloca anualmente em debate temas relevantes em prol da promoção, apoio e proteção ao aleitamento materno. “Possibilitando a amamentação: fazendo a diferença para mães e pais que trabalham” é o slogan deste ano. Embora a amamentação seja tradicionalmente considerada domínio da mãe, quando os pais, famílias e a sociedade a apoiam, as taxas aumentam. Diante disso, adotar uma abordagem inclusiva sobre o aleitamento materno que agregue pais, amigos, familiares, colegas de trabalho e comunidade é fundamental para criar um entorno propício, que permita que as mães amamentem de forma otimizada. Nesse contexto, convidamos a coordenadora da Assistência do Banco de Leite Humano do IFF/Fiocruz, Danielle Aparecida da Silva, para falar mais sobre o tema.

Effectiveness of a Postpartum Breastfeeding Support Group Intervention in Promoting Exclusive Breastfeeding and Perceived Self-Efficacy: A Multicentre Randomized Clinical Trial.

There are numerous recognized benefits of breastfeeding; however, sociocultural, individual, and environmental factors influence its initiation and continuation, sometimes leading to breastfeeding rates that are lower than recommended by international guidelines. The aim of this study was to evaluate the effectiveness of a group intervention led by midwives supporting breastfeeding during the postpartum period in promoting exclusive breastfeeding, as well as to assess the impact of this intervention on perceived self-efficacy. This was a non-blind, multicentric, cluster-randomized controlled trial. Recruitment started October 2021, concluding May 2023. A total of 382 women from Andalusia (Spain) participated in the study. The results showed that at 4 months postpartum there was a higher prevalence of breastfeeding in the intervention group compared to formula feeding (p = 0.01), as well as a higher prevalence of exclusive breastfeeding (p = 0.03), and also at 6 months (p = 0.01). Perceived self-efficacy was similar in both groups for the first two months after delivery, which then remained stable until 4 months and decreased slightly at 6 months in both groups (p = 0.99). The intervention improved the average scores of perceived self-efficacy and indirectly caused higher rates of exclusive breastfeeding (p = 0.005). In conclusion, the midwife-led group intervention supporting breastfeeding proved to be effective at maintaining exclusive breastfeeding at 6 months postpartum and also at increasing perceived self-efficacy.

Teleintervention's effects on breastfeeding in low-income women in high income countries: a systematic review and meta-analysis.

BACKGROUND: Many mothers in high-income countries (HIC) do not breastfeed to the World Health Organisation's recommendation of two years. This is particularly true for low-income women (LIW). They often face additional socio-structural barriers that encourage early discontinuation and are inadequately supported by current healthcare interventions. Teleinterventions are flexible and widely used following the global pandemic and increase maternal autonomy over intervention delivery. They show promise in improving other maternal conditions in LIW, including postpartum depression. Teleinterventions can increase breastfeeding rates in the wider maternal population, however their efficacy for this underserved population has not yet been systematically assessed. This meta-analysis aimed to identify if teleinterventions increase 'exclusive' or 'any' breastfeeding by LIW in HIC at 1-, 3-4, and 6-months postpartum. METHODS: We searched five online databases for randomised controlled trials assessing breastfeeding teleinterventions for LIW in HIC. Risk ratios (RR) were used to calculate the average effect of teleinterventions on 'any' and 'exclusive' breastfeeding at at 1-, 3-4, and 6-months postpartum using random effects meta-analysis. Study bias was assessed using the Revised Cochrane risk-of-bias tool for randomised trials (RoB2), and outcome quality was evaluated against GRADE criteria. RESULTS: Nine studies met inclusion criteria: six providing telephone calls, two text messages and one an online support group. All the studies were conducted in the United States, with small sample sizes and a high risk of bias. Pooled results indicate teleinterventions modestly increase 'any' and 'exclusive' breastfeeding at all time points, with a statistically significant increase in 'exclusive' breastfeeding after 3-4 months (RR 1.12, 95% CI [1.00,1.25]). At 3-4 months teleinterventions providing peer support were more effective than educational teleinterventions at promoting any and exclusive breastfeeding. Evidence for all outcomes were rated 'low' or 'very low' quality using the GRADE tool, mainly due to high attrition and low power. CONCLUSIONS: Despite insufficient high-quality research into breastfeeding teleinterventions for LIW, our results suggest teleinterventions may improve exclusive and any breastfeeding. Given breastfeeding is particularly low in LIW population from HIC, our findings are promising and require further exploration by larger, methodologically sound trials in other HIC.

[Prevalence of and risk factors for perceived absence of breast milk supply in Chinese lactating women in 2013].

OBJECTIVE: To investigate the prevalence and influencing factors of postpartum perceived absence of breast milk supply among Chinese mothers in 2013. METHODS: This is a cross-sectional study based on the data collected from children and mothers under 2 years of age in 2013 as part of the nutrition and health surveillance of Chinese residents. In this study, multistage stratified cluster sampling method was used to select subjects from 55 countires/districts in 30 provinces in China. The perceived absence of breast milk supply was defined as the mother's self-reported absence of breast milk and failure to breastfeed. Breastfeeding knowledge, maternal breastfeeding knowledge and general characteristics were collected through a structured questionnaire. Univariate analysis and Logistic regression were used to analyze the factors associated with perceived absence of breast milk supply. RESULTS: A total of 12091 mothers were included in the study, including 419 in the perceived non-breastfeeding group, the prevalence of perceived absence of breast milk supply was 3.5%. Multivariate Logistic regression showed maternal age(OR=1.04, 95%CI 1.02-1.06), postpartum hemorrhage(OR=2.03, 95%CI 1.30-3.16), and belief that breastfeeding should continue beyond 12 months of age(OR=0.27, 95%CI 0.17-0.45), not knowing how to breastfeed(OR=3.31, 95%CI: 2.31-4.74) were the main influencing factors for perceived absence of breast milk supply after delivery. CONCLUSION: Age, postpartum hemorrhage and knowledge level of breastfeeding are the main risk factors for perceived absence of breast milk supply, and knowledge level of breastfeeding is a modifiable factor.

Association between postpartum depression and breastfeeding self-efficacy in mothers: a systematic review and meta-analysis.

BACKGROUND: Depression is one of the most common mental disorders in the postpartum period. Depression can decrease self-efficacy in breastfeeding by reducing the mother's self-confidence. Considering the conflicting results regarding the relationship between postpartum depression and breastfeeding self-efficacy, this systematic review was conducted to investigate the relationship between breastfeeding self-efficacy and postpartum depression. METHOD: In this systematic review, published articles in PubMed, Scopus, Web of Sciences, Cochrane Library, and Google Scholar databases were searched using English keywords "Self-efficacy, breastfeeding, breastfeeding Self-efficacy, depression, postpartum depression" without publication date limit. Data analysis was done with employing STATA14 software. Heterogeneity was assessed using I2 index which was 0%. Therefore, the fixed effects method was used to combine the data and perform meta-analysis. RESULT: The results of the meta-analysis showed that based on the fixed effect method, depression was associated with decreased breastfeeding self-efficacy on the first day (SMD = 0.62, 95%CI: -0.830, -0.41, p = 0.0001) and on the third day (SMD = 0.84, 95% CI: -0.55,1.14, p = 0.0001). The Begg and Manzumdar test revealed no publication bias, with p = 0.317. CONCLUSION: Postpartum depression may be associated with a decrease in the mother's breastfeeding self-efficacy and placing mother in a condition to pay low attention to her maternal role. Therefore, healthcare providers should provide adequate support according to the needs of mothers and develop diagnostic and treatment protocols to improve the level of maternal health.

Lactation duration and development of type 2 diabetes and metabolic syndrome in postpartum women with recent gestational diabetes mellitus.

BACKGROUND: The World Health Organization and United Nations Children's Fund recommend exclusive breastfeeding (EBF) for the first six months of an infant's life. Although evidence suggests that maintaining breastfeeding has positive impacts on glucose and lipid metabolism in postpartum women with a history of gestational diabetes mellitus (GDM), no study has investigated whether such effects differ between breastfeeding intensities. This study aimed to evaluate the impact of maintaining breastfeeding on prediabetes, type 2 diabetes mellitus (T2DM), and metabolic syndrome (MetS) six months postpartum in women with GDM. This study also examined the potential variations in glucometabolic outcomes between EBF at six months and partial breastfeeding at six months. METHODS: This prospective cohort study included 130 women with recent GDM who experienced live births between 7 September 2020 and 31 January 2023 at a university hospital in Bangkok, Thailand. All the women were free of T2DM and MetS at baseline (six weeks postpartum). We followed up these women six months postpartum to assess their breastfeeding practices (EBF at six months, partial breastfeeding at six months, or not maintaining breastfeeding) and evaluate their progression to prediabetes, T2DM, and MetS. Maintaining breastfeeding was defined as breastfeeding for six months. EBF was determined using the "recall since birth" method. RESULTS: Of the 130 participants included, the rates of prediabetes, T2DM, and MetS six months postpartum were 33% (n = 43), 2% (n = 3), and 17% (n = 22), respectively. In the unadjusted model, maintaining breastfeeding was associated with a reduction in the risks of prediabetes and MetS but not T2DM. After adjusting for potential confounders, maintaining breastfeeding was a significant protective factor only for prediabetes. The adjusted risk ratios and 95% confidence intervals were 0.54 (0.29, 0.99) for prediabetes and 0.47 (0.19, 1.06) for MetS. When EBF at six months and partial breastfeeding at six months were separately analyzed, the risks of prediabetes and MetS differed between the two groups. In the EBF at six months-to-partial breastfeeding at six months comparison, the adjusted risk ratios (95% confidence intervals) of prediabetes and MetS were 0.46 (0.22, 0.97) vs. 0.79 (0.25, 2.49) and 0.34 (0.11, 0.99) vs. 0.69 (0.22, 2.07), respectively. CONCLUSIONS: Maintaining breastfeeding reduced the risk of prediabetes and MetS, but not of T2DM, six months postpartum; these effects were significant only with EBF. These findings indicate that supporting maternal efforts to practice EBF for six months may improve women's health after GDM.

A longitudinal investigation of breastfeeding planning, initiation, and duration among individuals with pre-pregnancy overweight or obesity.

Individuals with a body mass index (BMI)≥25 kg/m2 are less likely to initiate and continue breastfeeding than are those with BMIs<25. Given the intergenerational health benefits of breastfeeding, it is important to understand breastfeeding behaviors and their correlates among individuals with BMIs≥25. Thus, in an observational cohort with BMI≥25 (N = 237), we aimed to characterize longitudinal relationships among breastfeeding planning, initiation, and duration and their sociodemographic/clinical correlates and determine if pre-pregnancy BMI predicts breastfeeding planning, initiation, and duration. Breastfeeding behaviors, weight/BMI, and sociodemographic/clinical characteristics were assessed in early, mid, and late pregnancy, and at six-months postpartum. Most participants planned to (84%) and initiated (81%) breastfeeding, of which 37% breastfed for ≥6 months. Participants who were married, first-time parents, higher in education/income, and had never smoked tobacco were more likely to plan, initiate, and achieve ≥6 months of breastfeeding. Higher pre-pregnancy BMI was not associated with breastfeeding planning or initiation but was associated with lower adjusted odds of breastfeeding for ≥6 months relative to <6 months. Findings suggest that support aimed at extending breastfeeding among those with elevated pre-pregnancy BMI may be warranted. Future interventions should also address sociodemographic and clinical inequities in breastfeeding.

Assessment of the general health status of children in Turkey: A community-based cross-sectional study.

AIM: This study aims to assess the general health status and factors affecting the general health status in the 0-14 age group in Turkey. METHODS: This cross-sectional study was conducted using the Turkish Statistical Institute Turkey Health Survey 2022 micro data set. RESULTS: This study included 7019 participants. Household heads described the general health status of 91.3% of children and the dental and gum status of 82.4% of children as very good or good, and 9.2% of children had any chronic disease. Although the median breastfeeding duration was 15 months, there is statistical significant association between sex and general health status (p = 0.014) and sex and duration of breastfeeding (p = 0.006). A statistical difference was found between duration of breastfeeding and general health status (p = 0.009) and dental and gum status (p = 0.001). CONCLUSION: In 2022, the majority of children in Turkey had very good or good general health and dental and gum status. More than a third of children were breastfed for less than 12 months. Considering the possibility of neglecting oral and dental health problems, it is recommended to prioritize oral and dental health literacy trainings and to continue breastfeeding promotion programmes.

Exploring the profound link: Breastfeeding's impact on alleviating the burden of breast cancer - A review.

Breastfeeding has emerged as a critical factor in understanding and potentially mitigating the risk of breast cancer among women. This review delves into the intricate relationship between breastfeeding and breast cancer, elucidating the biological mechanisms, protective effects, and broader implications for public health. Epidemiological evidence consistently demonstrates a correlation between breastfeeding and a reduced risk of breast cancer, with longer durations of lactation showing a dose-dependent decrease in risk. The biological nexus between breastfeeding and breast cancer involves hormonal changes and the elimination of potentially damaged cells, influencing breast tissue and potentially mitigating carcinogenesis. Moreover, breastfeeding appears to impact tumor subtypes and aggressiveness, particularly demonstrating associations with lower risks of hormone receptor-negative and certain aggressive breast cancer subtypes. Recognizing the significance of breastfeeding in reducing breast cancer risk has profound public health implications, necessitating comprehensive support, education, and policies to encourage and facilitate breastfeeding.

Predictors of delayed initiation of breast milk and exclusive breastfeeding in Ethiopia: A multi-level mixed-effect analysis.

BACKGROUND: Despite the well-established benefits of early initiation of breastfeeding and exclusive breastfeeding for the first six months to promote optimal neonatal and child health, evidence indicates that in Ethiopia, a significant number of newborns initiate breastfeeding late, do not adhere to exclusive breastfeeding (EBF) for the recommended duration, and instead are fed with bottles. OBJECTIVE: To determine the proportion of delayed initiation of breast milk, exclusive breastfeeding, and its individual and community-level predictors among mothers in Ethiopia. METHODS: A secondary data analysis was done using the 2019 Ethiopian Mini Demographic Health Survey data. We examined a weighted sample of 2,012 children born within the past 24 months and 623 children aged 0-5 months at the time of the survey. The data analysis was done using STATA version 15. To understand the variation in delayed initiation and exclusive breastfeeding, statistical measures such as the Intraclass correlation coefficient, median odds ratio, and proportional change in variance were calculated. We employed a multilevel mixed-effects logistic regression model to identify predictors for each outcome variable. Statistical significance was determined with a p-value < 0.05. RESULTS: The proportion of delayed initiation of breast milk and exclusive breastfeeding were 24.56 and 84.5%, respectively. Women aged 34-49 years old (AOR = 0.33: 95% CI; 0.15-0.72), having a television in the house (AOR = 0.74: 95%CI; 0.33-0.97), delivered by cesarean section (AOR = 3.83: 95% CI; 1.57-9.32), and resided in the Afar regional state (AOR = 1.43: 95%CI; 1.03-12.7) were significantly associated with delayed initiation of breast milk. On the other hand, attended primary education (AOR = 0.67: 95%CI; 0.35-0.99), secondary education (AOR = 0.34: 95%CI; 0.19-0.53), women whose household headed by male (AOR = 0.68; 95% CI; 0.34-0.97), and rural residents (AOR = 1.98: 95%CI; 1.09-3.43) were significantly associated with exclusive breastfeeding practice. CONCLUSION: Health promotion efforts that encourage timely initation of breast milk and promote EBF, focused on young mothers, those who gave birth through cesarean section, and those residing in urban and the Afar regional state. Furthermore, government health policymakers and relevant stakeholders should consider these identified predictors when revising existing strategies or formulating new policies.

Association between breast feeding and food consumption according to the degree of processing in Brazil: a cohort study.

BACKGROUND: The benefits of breast feeding may be associated with better formation of eating habits beyond childhood. This study was designed to verify the association between breast feeding and food consumption according to the degree of processing in four Brazilian birth cohorts. METHODS: The duration of exclusive, predominant and total breast feeding was evaluated. The analysis of the energy contribution of fresh or minimally processed foods (FMPF) and ultra-processed foods (UPF) in the diet was evaluated during childhood (13-36 months), adolescence (11-18 years) and adulthood (22, 23 and 30 years). RESULTS: Those who were predominantly breastfed for less than 4 months had a higher UPF consumption (ß 3.14, 95% CI 0.82 to 5.47) and a lower FMPF consumption (ß -3.47, 95% CI -5.91 to -1.02) at age 22 years in the 1993 cohort. Exclusive breast feeding (EBF) for less than 6 months was associated with increased UPF consumption (ß 1.75, 95% CI 0.25 to 3.24) and reduced FMPF consumption (ß -1.49, 95% CI -2.93 to -0.04) at age 11 years in the 2004 cohort. In this same cohort, total breast feeding for less than 12 months was associated with increased UPF consumption (ß 1.12, 95% CI 0.24 to 2.19) and decreased FMPF consumption (ß -1.13, 95% CI -2 .07 to -0.19). Children who did not receive EBF for 6 months showed an increase in the energy contribution of UPF (ß 2.36, 95% CI 0.53 to 4.18) and a decrease in FMPF (ß -2.33, 95% CI -4 .19 to -0.48) in the diet at 13-36 months in the 2010 cohort. In this cohort, children who were breastfed for less than 12 months in total had higher UPF consumption (ß 2.16, 95% CI 0.81 to 3.51) and lower FMPF consumption (ß -1.79, 95% CI -3.09 to -0.48). CONCLUSION: Exposure to breast feeding is associated with lower UPF consumption and higher FMPF consumption in childhood, adolescence and adulthood.

Infant Oral Candidiasis and Bottle Cleaning Methods: A Descriptive Study.

As manufacturers produce bottles with additional parts, such as an anticolic straw, cleaning time increases. Increased cleaning time potentially decreases cleaning effectiveness and, thus, increases the chance for thrush. This study explored the relationship between the number of bottle parts and cleaning methods for bottle-fed-only infants (<13 months) presenting with oral candidiasis. After obtaining demographic information on eligible infants (via parental consent) from the chart, caregivers of 60 infants verbally completed a questionnaire. The questionnaire elicited information about the preferred bottle for feeding, number of parts, washing frequency, washing method, drying method, sterilization frequency, and sterilization method. The χ2 test, and Fisher's exact test when necessary, was performed to examine the relationship between each reported cleaning method (washing, drying, and sterilization) compared with the number of bottle parts (≤3 or ≥4). The number of bottle parts showed no association with bottle cleaning methods (p > .05). Although there were no statistically significant relationships, trends did present that warrant investigation. Future studies to confirm recommended practices for cleaning methods and identify those at risk from demographic data could positively affect the health of bottle-fed infants by reducing the occurrence of thrush.

Application of the integrated gateway model on child nutrition behaviors in Niger: An exploratory analysis.

OBJECTIVE: To identify potential gateway factors and behaviors that are associated with infant and young child feeding (IYCF) practices in the Maradi and Zinder regions of Niger through application of the Integrated Gateway Model. METHODS: We analyzed data from 2,727 married women of reproductive age including details on child feeding practices for their 2,551 children between the ages of 0 to 23 months. We assessed the association of three gateway behaviors (i.e., any antenatal care, facility delivery, and communication on nutrition practices) and gateway factors (i.e., behavioral determinants, exposure to information, decision-making agency, and woman's group participation) on four IYCF practices (i.e., early initiation of breastfeeding, exclusive breastfeeding, minimum meal frequency, and minimum dietary diversity) while controlling for age, parity, educational attainment, and household wealth. RESULTS: We found antenatal care was associated with exclusive breastfeeding of children 0-5 months [adjusted odds ratio (aOR): 1.17 (95% confidence interval (CI): 1.03-1.33)], and minimum meal frequency of children 6-23 months [aOR: 1.10 (95% CI: 1.03-1.17)], and facility delivery was associated with early initiation of breastfeeding among children 0-5 months [aOR: 2.08 (95% CI: 1.39-3.12)]. We found negative associations with exclusive breastfeeding and communication on nutrition practices with husbands, family/friends, and health workers. Exposure to nutrition messages through radio, women's groups participation, and with health workers was positively associated with minimum dietary diversity. Self-efficacy was positively associated with both early initiation of breastfeeding, exclusive breastfeeding among children 0-5 months and minimum dietary diversity among children 6-23 months. Women's agency was positively associated with early initiation of breastfeeding. CONCLUSION: The association of antenatal care and facility delivery with child nutrition outcomes suggest intervening before a woman becomes pregnant or early in her pregnancy could improve nutrition outcomes. Programs strengthening the continuum of care should identify gateway behaviors to maximize adoption of priority health behaviors.

Pumps: A Possible Tool to Promote More Equitable Lactation Outcomes.

Pregnant individuals and infants in the US are experiencing rising morbidity and mortality rates. Breastfeeding is a cost-effective intervention associated with a lower risk of health conditions driving dyadic morbidity and mortality, including cardiometabolic disease and sudden infant death. Pregnant individuals and infants from racial/ethnic subgroups facing the highest risk of mortality also have the lowest breastfeeding rates, likely reflective of generational socioeconomic marginalization and its impact on health outcomes. Promoting breastfeeding among groups with the lowest rates could improve the health of dyads with the greatest health risk and facilitate more equitable, person-centered lactation outcomes. Multiple barriers to lactation initiation and duration exist for families who have been socioeconomically marginalized by health and public systems. These include the lack of paid parental leave, increased access to subsidized human milk substitutes, and reduced access to professional and lay breastfeeding expertise. Breast pumps have the potential to mitigate these barriers, making breastfeeding more accessible to all interested dyads. In 2012, The Patient Protection and Affordable Care Act (ACA) greatly expanded access to pumps through the preventative services mandate, with a single pump now available to most US families. Despite their near ubiquitous use among lactating individuals, little research has been conducted on how and when to use pumps appropriately to optimize breastfeeding outcomes. There is a timely and critical need for policy, scholarship, and education around pump use given their widespread provision and potential to promote equity for those families facing the greatest barriers to achieving their personal breastfeeding goals.

Essential and non-essential element concentrations in human milk samples and the assessment of infants' exposure.

As the data concerning element concentrations in human milk (HM) samples and their intake by infants are lacking in Poland, the present study aimed to explore this issue. The material consisted of HM samples obtained from 30 exclusively breastfeeding mothers during 4-6 weeks postpartum. Additionally, to identify the factors that may potentially affect HM composition, information regarding maternal data (anthropometry, body composition, and diet) was also collected. Maternal diet was assessed with two methods-a food frequency questionnaire and 3-day dietary records. In total, 18 essential and non-essential elements were determined. For the elements analysis, we used inductively coupled plasma quadrupole mass spectrometry. Most of the elements (n = 11, 61%) were detected in all HM samples. In all HM samples tin concentration was higher (5.67 ± 2.39 µg/L) than the usual range reported by the World Health Organization (~ 1.0 µg/L). HM cadmium content was positively associated with maternal salty snacks intake (r = 0.502, p = 0.005), arsenic with whole-grain products intake (r = 0.37, p = 0.043), and mercury concentration with fruits and seeds/nuts consumption (r = 0.424, p = 0.042 and r = 0.378, p = 0.039, respectively). Higher HM lead concentration was predicted by maternal age (95% CI [0.94-0.97]), intake of fish (95% CI [1.01-1.03]), and vegetables (95% CI [1.02-1.06]). The highest infants' intake was observed for copper (35.24 ± 12.48) and the lowest for arsenic (0.076 ± 0.102). Infants' exposure to lead was associated with maternal frequency consumption of canned fish (p = 0.0045). There is a need to perform further research on this topic to maximize the benefits of breastfeeding by minimizing maternal and infant exposure to potentially toxic elements.
