Post-partum weight retention in Northeastern Brazilian women: a prospective NISAMI cohort study.

BACKGROUND: Weight retention during the post-partum period is associated with excessive weight gain. OBJECTIVES: To investigate factors associated with maternal weight retention at six months post-partum (PPWR). DESIGN AND SETTING: A prospective cohort study was conducted with 127 women monitored using prenatal services. METHODS: The outcome variable was represented by post-partum maternal weight retention and calculated as the difference between the mother's weight at sixth month post-partum and her pregestational weight. RESULTS: The mean age of the pregnant women was 26.7 ± 5.25 years old, and the post-partum maternal weight retention was 46.5%. The proximal determinants showed a direct association with PPWR after adjusting for the distal and intermediate variables: excessive gestational weight gain (odds ratio [OR]:3.34; confidence interval [CI]:1.16-9.59), greater adhesion to dietary intake pattern 2 (composed of red meats and derivatives, eggs, industrialized foods, and coffee) (OR:2.70; CI:1.16-6.32), and the absence of exclusive maternal breastfeeding in the first month (OR:3.40; CI:1.27-9.12), as well as primiparity (OR:2.36; CI:1.00-5.55), an intermediate determinant. Insufficient weight gain in pregnancy was inversely associated with the outcome (OR:0.35; CI:0.31-0.93). CONCLUSIONS: Among the hierarchical determinants, proximal factors were interrelated with maternal weight retention, indicating that excessive total weight gain, an inadequate dietary intake pattern, and the absence of exclusive maternal breastfeeding in the first month of life work as dampeners of the return to pre-gestational weight. Prepartum and post-partum care interventions can contribute to reducing excess weight in women.

Validation and calibration of the Food Consumption Frequency Questionnaire for pregnant women

ABSTRACT BACKGROUND: Few food frequency questionnaires (FFQ) have been validated for pregnant women, particularly those in small- and medium-sized cities in different regions of Brazil. OBJECTIVES: To validate and calibrate a semiquantitative FFQ for pregnant women. DESIGN AND SETTING: The study was validated with a sample of 50 pregnant women (≥ 18 years) enrolled in Brazilian prenatal services. METHODS: An FFQ and a 24-hour recall were used to evaluate dietary intake. Dietary variables were tested for normality and log-converted when asymmetrical. Pearson's Correlation Coefficient was used to validate the questionnaire. Linear regression was applied to extract calibration factors. All variables underlying the consumption analysis were adjusted for energy. RESULTS: The mean age of the pregnant women was 26 years ± 6.2 years; 58% were in their first trimester, and 30% were identified as overweight/obese. The Pearson correlation analysis results indicated that the FFQ overestimated energy and nutrient intake, whose coefficients ranged from −0.15 (monounsaturated fat) to 0.50 (carbohydrate). Adjusting for energy reduced the mean values of intake coefficients, which now ranged from −0.33 (sodium) to 0.96 (folate). The calibration analysis results indicated variation in the coefficients from −0.23 (sodium) to 1.00 (folate). Calibration produced satisfactory coefficients for the FFQ compared with the reference standard for energy, macronutrients, monounsaturated fat, cholesterol, vitamins B12/C, folate, sodium, iron, and calcium. CONCLUSIONS: After validating and calibrating tests, we observed that the FFQ was adequately accurate for assessing the food consumption of the pregnant women in this study.

Assistência pré-natal e amamentação exclusiva na atenção primária à saúde em um município do Sudoeste da Bahia / Prenatal care and exclusive breastfeeding in primary health care in a municipality in the Southwest of Bahia

Introdução: o aleitamento materno exclusivo deve ser promovido e fortalecido em todas as esferas públicas, especialmente na Atenção Primária à Saúde (APS), que tem o pré-natal como elemento importante para assistência e acompanhamento da mulher durante a gestação. Objetivo: identificar a associação entre assistência pré-natal e amamentação exclusiva em crianças menores de seis meses acompanhadas na APS em um município do Sudoeste da Bahia. Metodologia: estudo transversal, envolvendo 75 mães/crianças de zero a seis meses cadastradas no programa de Crescimento e Desenvolvimento do serviço de saúde do município de Jequié, Bahia, no período de março a agosto de 2018. Empregou-se o Teste de Qui-Quadrado de Pearson, para avaliar associação entre variáveis da assistência pré-natal e amamentação exclusiva. Resultados: a prevalência de aleitamento materno exclusivo registrado neste estudo foi de 36%.Observou-se que,mães com mais de seis consultas de pré-natal durante a gestação apresentaram maior prevalência de amamentação exclusiva (55,2%; p=0,019). A variável orientações sobre amamentação exclusiva no pré-natal não foi estatisticamente associada ao desfecho (0,457), porém descritivamente identificou-se que as mães que tiveram orientações durante o pré-natal apresentaram tendência de amamentar exclusivamente (56,7%; p= 0,457). Conclusão: a assistência pré-natal pode ser considerada elemento protetor na prática da amamentação exclusiva, e por isso a promoção e apoio ao aleitamento materno deve ser fortalecida na APS.

Introduction: exclusive breastfeeding should be promoted and strengthened in all public spheres, especially in Primary Health Care (PHC), which has prenatal care as an important element for the assistance and monitoring of women during pregnancy. Objective:to identify the link between prenatal care and exclusive breastfeeding in children younger than six months followed up in the PHC in a municipality in the Southwest of Bahia. Methodology: cross-sectional study, with 75 mothers/children aged zero to six months enrolled in the Growth and Development program of the health service in the municipality of Jequié, Bahia, from March to August 2018. Pearson's Chi-Square Test was used to assess the association between prenatal care variables and exclusive breastfeeding. Results: the prevalence of exclusive breastfeeding recorded in this study was 36%. It was observed that mothers with more than six prenatal consultations during pregnancy had a higher prevalence of exclusive breastfeeding (55.2%; p=0.019). The variable guidance on exclusive breastfeeding during prenatal care was not statistically associated with the outcome (0.457), however it was descriptively identified that mothers who received guidance during prenatal care tended to breastfeed exclusively (56.7%; p= 0.457 ). Conclusion:prenatal care can be considered a protective element in the practice of exclusive breastfeeding, and therefore the promotion and support of breastfeeding should be strengthened in PHC.

Influence of conditional cash transfer program on prenatal care and nutrition during pregnancy: NISAMI cohort study.

BACKGROUND: There are few studies on the influence of a cash transfer program on nutritional outcomes from pregnancy. OBJECTIVES: To analyze how a Brazilian conditional cash transfer program (Bolsa Familia Program, BFP) was associated with changes in body mass index (BMI) and food consumption among pregnant women. DESIGN AND SETTING: Cohort study on 250 pregnant women (≥ 18 years of age) in Brazilian prenatal services. METHODS: A food frequency questionnaire was used to evaluate dietary intake. Weight was measured in each gestational trimester. Generalized estimation equations and structural equation modeling were used for statistical analyses. Correlations were analyzed using standardized coefficients (SCs). RESULTS: Women benefitting from the BFP were of greater age and had lower education. The BFP exerted a direct negative effect on the pregnant women's consumption choices regarding refined grains, regional foods, vegetable oil, sausages, salted meats and snacks (SC = -0.10) and on maternal BMI (SC = -0.12). Among the intermediate variables, we observed that the time elapsed since pregnancy and the month of prenatal onset had direct negative effects; and that the number of visits to doctors, family income and number of years of education had direct positive effects. CONCLUSIONS: Beneficiaries were less likely to increase their BMI outside of the recommended standards and had a greater tendency to receive prenatal care. Participation in the BFP had a direct negative effect on adherence to unhealthy diets.

Investigation of maternal polymorphisms in genes related to glucose homeostasis and the influence on birth weight: a cohort study

Abstract Objectives: To contribute to a better understanding of the maternal genetic mechanisms that influence obstetric outcomes and that are involved in maternal and child health, this study aimed to evaluate the association between maternal genetic variants and the offspring birth weight by analyzing single-nucleotide polymorphisms (SNPs) in genes related to glucose homeostasis. Methods: Three polymorphisms were analyzed (GCK rs1799884, TCF7L2 rs7903146 and LEPR rs1137101) in 250 pregnant women who participated in a Brazilian prospective cohort study. Genotyping was performed by Real-Time Polymerase Chain Reaction (qPCR) using pre-designed TaqMan® SNP genotyping assays. Vitamin D dosage was performed by chemiluminescence. Variance, Pearson's chi-square test and multiple linear regression were used for the statistical analysis. Results: It was possible to verify a significant association between birth weight and maternal GCK rs1799884 when obstetric outcomes, clinical and anthropometric characteristics were taken into consideration. The children of homozygous women for the minor allele GCK rs1799884 presented lower birth weight (β = -335.25, 95% CI = -669.39; -1.17, p = 0.04). Furthermore, a direct link between a leptin receptor variant and gestational duration was found (p = 0.037). Conclusion: The variant GCK rs1799884 (mm) was associated with a reduction in newborn weight in the miscegenated Brazilian population.

FADS1 and FADS2 Gene Polymorphisms Modulate the Relationship of Omega-3 and Omega-6 Fatty Acid Plasma Concentrations in Gestational Weight Gain: A NISAMI Cohort Study.

The polymorphisms of fatty acid desaturase genes FADS1 and FADS2 have been associated with an increase in weight gain. We investigated FADS1 and FADS2 gene polymorphisms and the relation between ω-3 and ω-6 fatty acid plasma concentrations and gestational weight gain. A prospective cohort study of 199 pregnant women was followed in Santo Antônio de Jesus, Brazil. Plasma levels of polyunsaturated fatty acids (PUFAs) were measured at baseline and gestational weight gain during the first, second, and third trimesters. Fatty acid recognition was carried out with the aid of gas chromatography. Single nucleotide polymorphisms (SNPs) were genotyped using real-time PCR. Statistical analyses included Structural Equation Modelling. A direct effect of FADS1 and FADS2 gene polymorphisms on gestational weight was observed; however, only the SNP rs174575 (FADS2) showed a significant positive direct effect on weight over the course of the pregnancy (0.106; p = 0.016). In terms of the influence of SNPs on plasma levels of PUFAs, it was found that SNP rs174561 (FADS1) and SNP rs174575 (FADS2) showed direct adverse effects on plasma concentrations of ω-3 (eicosapentaenoic acid and alpha-linoleic acid), and only SNP rs174575 had positive direct effects on plasma levels of ARA and the ARA/LA (arachidonic acid/linoleic acid) ratio, ω-6 products, while the SNP rs3834458 (FADS2) had an adverse effect on plasma concentrations of EPA, leading to its increase. Pregnant women who were heterozygous and homozygous for the minor allele of the SNP rs3834458 (FADS2), on the other hand, showed larger concentrations of series ω-3 substrates, which indicates a protective factor for women's health.

Socioeconomic and nutritional aspects of pregnant women assisted by Programa Bolsa Família: cohort NISAMI.

The objective of this study was to evaluate the socioeconomic and nutritional assistance factors of pregnant women who are beneficiaries of the Bolsa Família Program and were attended at a prenatal service in the city of Recôncavo da Bahia. A cohort study was conducted with 250 pregnant women from the prenatal service in 16 Family Health Units from August 2013 to December 2014. A structured and previously tested questionnaire was used to collect data. Socioeconomic and nutritional variables were used. It was identified that the average age was 28.3 years, of these, 85.2% studied until high school, 72.4% of pregnant women reported having income less than or equal to two minimum wages, with a mean of 1,036.3 and 26.8% reported receiving the benefit. It was observed that 40% had a pre-gestational Body Mass Index of overweight, 38% presented adequate weight gain for Gestational Age; 90.57% performed more than 7 consultations and 75.6% reported that they made use of alcoholic beverages or stopped in the gestation. The Bolsa Família Program as an integrated strategy for social inclusion and economic development seems to have a protective effect on the nutritional health of pregnant women in the municipality.

Polyunsaturated fatty acid consumption and weight gain during pregnancy: NISAMI Cohort study.

OBJECTIVES: Few studies have investigated the influence of polyunsaturated fatty acid consumption on excessive weight gain during pregnancy. Thus, we analyzed the association between the intake of polyunsaturated fatty acids (ω-6 and ω-3) and weight gain in women during pregnancy. METHODS: This is a cohort study of 250 pregnant women enrolled in municipal pre-natal services. Weight, height, and dietary intake of polyunsaturated fatty acids were evaluated at the baseline. The semi-quantitative food frequency questionnaire was employed to assess the main exposure. Gestational weight was measured in the first, second, and third trimesters. A dietary pattern involving the consumption of fatty acids was identified through factor analysis. A generalized estimating equation was used for the data analysis. RESULTS: The prevalence of excessive weight gain at the end of pregnancy was 35.2%. Consumption patterns 1 (salted meats, offal, vegetable oil, snacks, legumes, and oleaginous foods) and 2 (red meat, sausages, butter, margarine, mayonnaise, acarajé, caruru, vatapá, and refined cereals) revealed a risk for the accumulation of excess weight during pregnancy. Women who adhered to consumption patterns 1 (RR: 2.39; 95% CI: 1.44-3.94) and 2 (RR: 2.39; 95% CI: 1.44-3.94) were more susceptible to excess weight gain during pregnancy. CONCLUSIONS: Women who adhered to dietary patterns involving foods that are sources of ω-6 fatty acids and saturated fatty acids were more susceptible to gaining weight during pregnancy compared to those who adhered less to these patterns.

Determinantes sociais e biológicos da mortalidade infantil no Recôncavo da Bahia / Social and biological determinants of child mortality in the Recôncavo of Bahia

Introdução: o Recôncavo é um território de identidade da Bahia propenso a sofrer mais iniquidades sociais, o que pode gerar repercussões negativas nas condições de vida e saúde das crianças e, assim, impactar no Coeficiente de Mortalidade Infantil (CMI). Objetivo: analisar a associação entre os determinantes sociais e biológicos da saúde e a mortalidade infantil nos municípios do Recôncavo da Bahia, no período de 2010 a 2019. Metodologia: estudo ecológico, com dados de Sistemas de Informações em Saúde. Dados de CMI por 1000 nascidos vivos (NV) foram avaliados temporalmente no Recôncavo da Bahia, do ano de 2010 a 2019. Regressão Quantílica foi utilizada para análise do desfecho (CMI) e variáveis de exposição (determinantes). Resultados: o CMI no Recôncavo da Bahia apresentou importantes variações no período avaliado, passando de 9,7/1.000NV em 2010, para 13,1/1.000NV em 2019. Identificou-se associação positiva do CMI com Índice de Gini e uma associação inversa entre o CMI e Índice de Desenvolvimento Humano Municipal (IDHM). Conclusão: no período de 2010 a 2019 houve um aumento de 35% no CMI, no Recôncavo da Bahia. A mortalidade infantil no Recôncavo da Bahia é determinada socialmente pelo Índice de Gini e IDHM. As condições de saúde das crianças podem sofrer consequências em um contexto de aumento da vulnerabilidade social e políticas de subfinanciamento da saúde.

Introduction: the Recôncavo is an identity territory in Bahia that is prone to suffering more social inequities, which can generate negative repercussions on the living conditions and health of children and, thus, impact on the Infant Mortality Rate (IMR). Objective: to analyze the association between the social and biological determinants of health and infant mortality in the municipalities of Recôncavo of Bahia, in the period 2010-2019. Methodology: ecological study, using data from Health Information Systems. IMR data per 1,000 live births (LB) were temporally evaluated in the Recôncavo of Bahia, from 2010 to 2019. Quantile Regression was used for outcome analysis (IMR) and exposure variables (determinants). Results: the IMR in the Recôncavo of Bahia showed important variations in the evaluated period, going from 9.7/1,000LB in 2010, to 13.1/1,000LB in 2019. A positive association was identified between IMR with Gini Index and an inverse association between the IMR and Municipal Human Development Index (MHDI). Conclusion: in the period of 2010-2019 there was an increase of 35.0% in the IMR, in the Recôncavo of Bahia. Infant mortality in the Recôncavo of Bahia is socially determined by the Gini Index and MHDI. Children's health conditions can suffer consequences in a context of increased social vulnerability and underfunded health policies.

Dietary intake of university students during COVID-19 social distancing in the Northeast of Brazil and associated factors.

This study aimed to analyze the influence of COVID-19 social distancing on the dietary pattern of university students in the Northeast of Brazil and associated factors. This is a cross-sectional study of 955 students from four universities carried out via a web survey containing social, economic, demographic, and health information. A food frequency questionnaire was used to evaluate diet. Weight and dietary alterations were reported. Exploratory factor analysis and multivariate logistic regression were used as statistical analyses. The mean age was 26 and 53.7% of the students observed an increase in their weight. Four dietary patterns were identified: (1) a predominantly in natura pattern, (2) a pattern of processed and ultra-processed foods, (3) a protein-based pattern, and (4) an infusion-based pattern. It was observed that students having a darker skin colour (OR 1.8; CI 95% 1.3-2.6) and 19-29 years old and not being a health course student (OR 1.5; CI 95% 1.1-2.1) were associated with greater adhesion to the in natura pattern. Not engaging in physical activity was statistically associated with not adhering (OR 0.5; CI 95% 0.4-0.7) to that pattern. The university students who saw an alteration in their weight during the social distancing period studied presented a greater probability of consuming the processed and ultra-processed foods pattern (OR 1.8; CI 95% 1.2-2.6), while the men (OR 0.7; CI 95% 0.4-0.9) and those not engaging in physical activity (OR 0.7; CI 95% 0.5-0.9) presented less adhesion to that pattern. These findings indicate that social isolation affected the dietary intake of university students, with adhesion to mixed dietary patterns in terms of health. The adhesion to the pattern of processed and ultra-processed foods identified may affect the students' health, especially the occurrence of excess weight and obesity.

Estado antropométrico pré-gestacional e peso ao nascer: Coorte NISAMI / Pre-gestational anthropometric status and birth weight: NISAMI cohort

objetivo do estudo foi analisar a relação entre o Índice de Massa Corporal pré-gestacional (IMCpg) e peso do recém nascido no município de Santo Antônio de Jesus-BA. Estudo de coorte prospectivo, com 185 gestantes e seus respectivos recém-nascidos, atendidas nas Unidades Básicas de Saúde, de abril de 2012 a novembro de 2013. O IMC pré-gestacional foi realizado com dados do peso referido e estatura aferida no dia da aplicação do questionário. O teste de Kolmogorov–Smirnov foi realizado para análise da normalidade dos dados. Estimou-se a associação entre o estado nutricional pré gestacional e os desfechos perinatais, por meio do Risco Relativo e intervalo de confiança de 95%. Das 185 mulheres, 44,9% iniciaram a gestação com algum desvio ponderal. As mulheres com baixo peso e sobrepeso apresentaram associação positiva para peso insuficiente ao nascer (<3000g), sendo as com baixo peso (RR=2,2; IC95%=0,5-9,5) e sobrepeso (RR=1,1; IC95%=0,5-2,6), enquanto as obesas apresentaram associação negativa (RR=0,8; IC95%=0,3-2,7). Apenas as mulheres com baixo peso apresentaram risco para baixo peso ao nascer (RR=3,1; IC95%=0,3-30,7). Esses dados revelam que o estado antropométrico pré-gestacional influencia no desenvolvimento da gestação e as inadequações nutricionais configuradas em períodos anteriores à concepção são considerados fatores determinantes para o peso da criança. Os desvios ponderais pré gestacionais apresentaram associação positiva com o peso inadequado ao nascer, o que sugere a necessidade de cuidados nutricionais pré-concepcionais. Assistência à saúde a mulheres em idade fértil poderá auxiliar em melhores desfechos gestacionais.(AU)

The aim of this study was to analyze the relationship between the pre-gestational Body Mass Index (BMIpg) and the newborn's weight in the municipality of Santo Antônio de Jesus, BA. This was a prospective cohort study, with 185 pregnant women and their respective newborns, attended at the Basic Health Units, from April 2012 to November 2013. The pre-gestational BMI was performed with data of their referred weight and height measured on the day of application of the questionnaire. The Kolmogorov – Smirnov test was performed to analyze the normality of the data. The association between pre-pregnancy nutritional status and perinatal outcomes was estimated through the Relative Risk and 95% confidence interval. Of the 185 women, 44.9% started the pregnancy with some weight deviation. Underweight (RR = 2.2; 95% CI = 0.5-9.5) and overweight (RR = 1, 1; 95% CI = 0.5-2.6) women showed a positive association with insufficient birth weight (<3000g), while obese women presented a negative association (RR = 0.8; 95% CI = 0.3-2.7). Only underweight women were at risk for low birth weight (RR = 3.1; 95% CI = 0.3-30.7). These data reveal that the pre-gestational anthropometric status influences the development of pregnancy and the nutritional inadequacies configured in periods prior to conception are considered determining factors for the child's weight. Pre-pregnancy weight deviations were positively associated with inadequate birth weight, which suggests the need for preconception nutritional care. Health care for women of childbearing age may assist in better pregnancy outcomes.(AU)

Estado antropométrico pré-gestacional e peso ao nascer: Coorte NISAMI / Pre-gestational anthropometric status and birth weight: NISAMI cohort

O objetivo do estudo foi analisar a relação entre o Índice de Massa Corporal pré-gestacional (IMCpg) e peso do recém-nascido no município de Santo Antônio de Jesus-BA. Estudo de coorte prospectivo, com 185 gestantes e seus respectivos recém-nascidos, atendidas nas Unidades Básicas de Saúde, de abril de 2012 a novembro de 2013. O IMC pré-gestacional foi realizado com dados do peso referido e estatura aferida no dia da aplicação do questionário. O teste de Kolmogorov­ Smirnov foi realizado para análise da normalidade dos dados. Estimou-se a associação entre o estado nutricional pré-gestacional e os desfechos perinatais, por meio do Risco Relativo e intervalo de confiança de 95%. Das 185 mulheres, 44,9% iniciaram a gestação com algum desvio ponderal. As mulheres com baixo peso e sobrepeso apresentaram associação positiva para peso insuficiente ao nascer (<3000g), sendo as com baixo peso (RR=2,2; IC95%=0,5-9,5) e sobrepeso (RR=1,1; IC95%=0,5-2,6), enquanto as obesas apresentaram associação negativa (RR=0,8; IC95%=0,3-2,7).

Vivências relacionadas ao aleitamento materno e sua interrupção precoce: estudo qualitativo com nutrizes / Experiences related to breastfeeding and its early interruption: a qualitative study with nursing mothers / Experiencias relacionadas con la lactancia y su interrupción temprana: estudio cualitativo con nutrices

O curso da amamentação é influenciado por diversos fatores correlacionados, que podem favorecer ou não a manutenção do aleitamento. Sendo assim, é fundamental conhecer os fatores que levam a tal interrupção em diferentes contextos. Este estudo objetivou compreender a vivência em relação ao aleitamento materno e sua interrupção precoce entre nutrizes em um serviço de atenção básica à saúde, de um município na Bahia. Trata-se de uma pesquisa de abordagem qualitativa, descritiva e analítica, realizada por meio de entrevistas semiestruturadas, aplicadas às nutrizes que interromperam precocemente o aleitamento materno dos filhos. Ao todo, foram entrevistadas 14 nutrizes com idade entre 19 e 40 anos. As entrevistas foram gravadas e transcritas, para posterior análise dos conteúdos das falas e organização em categorias analíticas. Entre as principais alegações para a interrupção foram citados mitos de "leite fraco", "pouco leite" e "leite secou", as intercorrências mamárias, o retorno da mulher ao âmbito de trabalho e aos estudos, bem como as experiências e vivências das nutrizes durante o curso da amamentação. Assim, constata-se que o ato de amamentar envolve uma série de fatores, que necessitam ser abordados, superando a ideia da amamentação plena e sem dificultadores, para que, apoiadas, essas mulheres possam reconhecer os desafios, mas principalmente os ganhos da prática da amamentação. O ato de amamentar envolve questões complexas, despertando nas mulheres sentimentos tanto positivos quanto negativos que se embricam com a escolha de manutenção do aleitamento materno exclusivo. Dessa forma, é importante que os profissionais de saúde compreendam o contexto social e cultural em que a mulher está inserida, colocando-a como protagonista nesse processo.

Breastfeeding is influenced by several correlated factors, which may favor or disadvantage its maintenance, thus it is necessary to know those factors that lead to such interruption in different contexts. This qualitative, descriptive and analytical study investigates the experience regarding breastfeeding and its early interruption among nursing mothers in a primary healthcare service in Bahia, Brazil. Data was collected by means of semi-structured interviews with nursing mothers who interrupted early the breastfeeding of their children. In all, 14 nursing mothers, aged between 19 to 40 years, were interviewed. After being recorded, the interviews were transcribed for later content analysis and organization into analytical categories. Among the main reasons for interrupting breastfeeding were the myths of "weak milk," "little milk," and "dried-up milk." Breast complications, the women's return to the workplace and university, as well as the experiences of nursing mothers during breastfeeding. Hence, it appears that the act of breastfeeding involves a series of factors that need to be addressed, overcoming the idea of full breastfeeding and without hindrances, so that, with support, these women can recognize the challenges, but especially the gains of breastfeeding. The act of breastfeeding involves complex issues, awakening in women both positive and negative feelings that become entangled with the choice of maintaining exclusive breastfeeding. Thus, health professionals must understand the social and cultural context in which women are inserted, placing them as protagonists in this process.

El curso de la lactancia materna está influenciado por diversos factores correlacionados, que pueden favorecer o no el mantenimiento de la lactancia materna. Por eso, es fundamental conocer los factores que conducen a dicha interrupción en diferentes contextos. Este estudio tuvo como objetivo comprender la experiencia con respecto a la lactancia materna y su interrupción temprana entre nutrices en un servicio de atención básica de salud de un municipio de Bahía (Brasil). Esta es una investigación cualitativa, descriptiva y analítica, realizada a través de entrevistas semiestructuradas, aplicadas a nutrices que interrumpieron tempranamente la lactancia materna de sus hijos. En total, se entrevistó a catorce madres lactantes de entre 19 y 40 años. Las entrevistas fueron grabadas y transcritas para el posterior análisis de los contenidos del discurso y la organización en categorías analíticas. Las principales explicaciones de la descontinuación se relacionaron con los mitos de "leche débil", "poca leche" y "se secó la leche", las complicaciones de los senos, el regreso de la mujer al trabajo y los estudios, así como las experiencias de madres lactantes durante el curso de la lactancia materna. Por lo tanto, parece que el acto de amamantar implica una serie de factores que deben abordarse, superando la idea de la lactancia materna completa y sin obstáculos, para que estas mujeres puedan reconocer los desafíos, pero especialmente los logros de la práctica de la lactancia materna. La lactancia materna involucra problemas complejos, que despiertan en las mujeres sentimientos positivos y negativos que se adoptan con la opción de mantener la lactancia materna exclusiva. Así, es importante que los profesionales de la salud entiendan el contexto social y cultural en el que se insertan las mujeres, ubicándolas como protagonistas en este proceso.
