Factors associated with breastfeeding abandonment in the first month after the mother's return to work

The return to work of lactating mothers has been identified as an important risk factor for breastfeeding interruption. We proposed to identify factors associated with breastfeeding abandonment in the first month after return. 252 women working at a hospital who had children aged 12 to 36 months and who were still breastfeeding when returned to work answered a questionnaire containing questions on sociodemographic characteristics, pregnancy, childbirth, breastfeeding and work-related factors. The associations were estimated using adjusted prevalence ratio (aPR), calculated with the hierarchical Poisson multivariable regression model. The following factors showed a significant association with breastfeeding abandonment: using a pacifier (aPR 4.58), cohabiting with someone other than partner (aPR 3.77), having no intention or having doubts about maintaining breastfeeding after returning (aPR 3.39), having a college degree (aPR 2.66), having no support from the infant's caregiver (aPR 2.26), and infant being older when the woman returned to work (PR 1.16 for each additional month of infant age). Longer duration of exclusive breastfeeding was a protective factor (aPR 0.990). Most of the factors associated with discontinuation of breastfeeding in the first month after the mother's return to work are not directly related to the woman's work.

Psychometric properties of the Child Development Assessment Questionnaire (QAD-PIPAS) for use in population studies involving Brazilian children aged 0-59 months

OBJECTIVE

To analyze the psychometric properties of the Child Development Assessment Questionnaire (QAD-PIPAS).

METHODS

This methodological study was comprised of two axes. The first one aimed to analyze the instrument's construct validity (discriminant and concurrent validity) and internal consistency, and the second one examined test-retest reliability, involving two different samples and procedures. For construct validity and internal consistency, the sample was recruited in Embu das Artes-SP, Brasilia-DF and Recife-PE during the immunization campaign in 2017, involving caregivers of 2005 children under 60 months of age (1295 under 36 and 710 from 37 to 59 months). For the test-retest analysis the sample consisted of 30 children aged 0-59 months old that attended daycare centers in Embu das Artes-SP in 2018.

RESULTS

Multivariate analyses of construct validity showed that the QAD-PIPAS was able to identify the association between the outcome (suspected child development delays) and expected risk and protective factors based on Nurturing Care Framework (OMS/UNICEF). A significant positive correlation was achieved between the scores of the QAD-PIPAS and CREDI in six of the eight age groups analyzed, with the most significant correlations being in the age groups from 25 to 30 and 31-36 months. Acceptable internal consistencies were identified in all age groups, with better performance above 36 months of age (Cronbach's alpha between 0.61 to 0.80). We also found an adequate test-retest reliability (global Kappa 0.81).

CONCLUSION

The QAD-PIPAS showed evidence of construct validity and reliability to be used in population studies involving children aged 0-59 months during multi-vaccination campaigns in Brazil.

All day-long pacifier use and intelligence quotient in childhood: A birth cohort study

BACKGROUND

Literature on pacifier use remains controversial, but mostly suggests an inverse association with childhood intelligence.

OBJECTIVES

The objective of this study was to assess the association between pacifier use and intelligence quotient (IQ) in six-year-old children from a birth cohort.

METHODS

Data from 3532 children from the 2004 Pelotas (Brazil) Birth Cohort were analysed. Children were recruited and assessed at birth and followed up at 3 months, and 1, 2, 4, and 6 years. Data on pacifier use duration and intensity were obtained via interviews with mothers in all six follow-up visits. IQ was estimated at 6 years using the Wechsler Intelligence Scale for Children and standardised for the analyses. Crude and adjusted coefficients were calculated (linear regression) for all the data collected in follow-up assessments for pacifier use.

RESULTS

IQ was inversely associated with all pacifier use indicators. Children who used a pacifier all day long (ADL) at any follow-up showed an IQ 0.18 (95% confidence interval [CI] 0.11, 0.24) standard deviations below those who never used it ADL, after adjusting for confounders. The strength of association increased with number of assessments reporting ADL pacifier use, from a reduction in IQ of 0.13 (95% CI 0.06, 0.21) to 0.34 (95% CI 0.15, 0.52) standard deviations for ADL use in one and in all four follow-up visits, respectively.

CONCLUSIONS

We found a strong association between intense pacifier use up to 4 years of age and lower IQ at 6 years. A dose-response gradient was observed, with greater IQ deficits in children who used a ADL pacifier for longer durations. The mechanisms underlying this association need to be clarified. One hypothesis is that children using a pacifier, especially those who use it more intensely, are less stimulated.

Development and validation of an instrument for monitoring child development indicators

OBJECTIVE

To create and validate an instrument for child development monitoring.

METHODS

Methodological study, based on the World Bank's proposition to monitor child development indicators in low- and middle-income countries. The stages of the study included the following: development of an inventory of items for child development evaluation, based on open access instruments; content validation by a group of experts on the topic, using consensus techniques; selection of questions to describe children and their families; pre-test of the instrument during the vaccination campaign in 2016 in three municipalities, and conducting cognitive interviews.

RESULTS

A total of 431 items were sent for the evaluation of the specialists; 77 were initially excluded and the others were evaluated in-person by the group, with 162 items covering the motor, cognitive, language, and socio-emotional domains, distributed in ten age ranges. Questions about health, nutrition, early learning, protection and safety, and responsive care were also included. The instrument was applied by volunteer undergraduate students to 367 mothers of children under 5 years, showing good adherence of the caregivers. The time of application of the questionnaire was, on average, 20minutes. The cognitive interviews allowed the final adjustment of 19 items of the instrument for better understanding by the caregivers.

CONCLUSIONS

The instrument created and validated by experts fills a gap, as it allows a comprehensive evaluation of the development of children under 5 years at the population level, using a fast and inexpensive tool, and can be useful for monitoring indicators of development in Brazilian children in vaccination campaigns.

Factors associated with the maintenance of breastfeeding for 6, 12, and 24 months in adolescent mothers

BACKGROUND

Previous studies have demonstrated that adolescent mothers present a higher risk of not breastfeeding or of early interruption of this practice. Considering the scarcity of studies investigating the determining factors of breastfeeding in adolescent mothers, and the absence of studies exploring the determining factors of breastfeeding maintenance for different periods of time in a single population of adolescent mothers, the aim of this research was to identify factors associated with breastfeeding maintenance for at least 6, 12, and 24 months in adolescent mothers.

METHODS

Data analysis from a randomised control trial involving adolescent mothers recruited at a university hospital in southern Brazil. Participants were followed through the first year of life of their infants and reassessed at 4-7 years. Factors associated with any breastfeeding for at least 6, 12, and 24 months were assessed using multivariate Poisson regression.

RESULTS

Data for 228, 237, and 207 mothers were available, respectively. Breastfeeding maintenance for at least 6, 12, and 24 months was observed in 68.4, 47.3, and 31.9% of the sample, respectively. Only one factor was associated with breastfeeding maintenance at all outcomes: infant not using a pacifier showed a higher probability of breastfeeding maintenance in the first 2 years. Maternal grandmother breastfeeding support and exclusive breastfeeding duration were associated with breastfeeding maintenance for 6 and 12 months. The other factors evaluated were associated with breastfeeding maintenance at only one of the time points assessed: 6 months, maternal skin color (black/brown); 12 months, female infant and partner breastfeeding support; and 24 months, older paternal age and multiparity.

CONCLUSIONS

The present findings shed light upon barriers and facilitators of breastfeeding practices among adolescent mothers. In order to contribute to the challenge of increasing BF duration among adolescent mothers interventions aimed at boosting breastfeeding maintenance among this population should take into consideration the determining factors here identified. Additionally, breastfeeding education and support should be provided continuously as factors influencing these practices vary with time. Thus, support for adolescent mothers during the different stages of breastfeeding need to be tailored to have a positive impact on breastfeeding experience.

Population-Based Study on the Practice of Breastfeeding in Children Born with Cleft Lip and Palate

Objective

To investigate the practice of breastfeeding and related difficulties in children born in Porto Alegre, Brazil, with cleft lip, cleft palate, and cleft lip with cleft palate.

Design

Cohort, observational, and population-based study.

Population and Sample

Mothers of all children born in 2001 and 2002 with cleft lip and palate in the city of Porto Alegre, Brazil (n = 31), were interviewed in their homes. From the information collected, the frequencies of breastfeeding and exclusive breastfeeding in the first year of life were estimated and the median duration was computed according to the type of cleft. A descriptive analysis was used to study the difficulties.

Main Indicators

Initiation rate, pattern, duration, and difficulties of breastfeeding and exclusive breastfeeding.

Results

The initiation rate of breastfeeding was 100% and its median duration was 42.5 days. Exclusive breastfeeding was initiated by 67.7% of the sample and maintained for 15 days (median). The breastfeeding duration was significantly higher in the presence of cleft lip, being equal or even superior to (in the case of exclusive breastfeeding) the median of Porto Alegre's general population. The most frequently mentioned difficulties were weak suction, difficulty attaching to the breast, and breast milk escaping through the nostrils.

Conclusions

In spite of the diverse difficulties reported and the lack of professional support after discharge from the maternity wards, the initiation rate and the duration of breastfeeding of children with cleft lip and palate found in this study reinforce the theory that this malformation, especially cleft lip, is compatible with successful breastfeeding.

Infant feeding: beyond the nutritional aspects

OBJECTIVE

To draw attention to the importance of interaction between caregiver and child during feeding and the influence of parenting style on dietary habit formation.

SOURCE OF DATA

A search was performed in the PubMed and Scopus databases for articles addressing responsive feeding; the articles considered most relevant by the authors were selected.

SYNTHESIS OF DATA

The way children are fed is decisive for the formation of their eating habits, especially the strategies that parents/caregivers use to stimulate feeding. In this context, responsive feeding has been emphasized, with the key principles: feed the infant directly and assist older children when they already eat on their own; feed them slowly and patiently, and encourage children to eat but do not force them; if the child refuses many types of foods, experiment with different food combinations, tastes, textures, and methods of encouragement; minimize distractions during meals; and make the meals an opportunity for learning and love, talking to the child during feeding and maintaining eye contact. It is the caregiver's responsibility to be sensitive to the child's signs and alleviate tensions during feeding, and make feeding time pleasurable; whereas it is the child's role to clearly express signs of hunger and satiety and be receptive to the caregiver.

CONCLUSION

Responsive feeding is very important in dietary habit formation and should be encouraged by health professionals in their advice to families.

Trends in breastfeeding indicators in a city of northeastern Brazil

OBJECTIVE

To investigate trends in breastfeeding indicators in the city of Feira de Santana, Brazil, and to identify population characteristics that might have influenced this trend.

METHODS

Three methodologically comparable cross-sectional surveys performed in 1996, 2001, and 2009 were analyzed. These involved 2,159, 2,319, and 1,471 children younger than 1 year of age who were vaccinated in national multivaccination campaigns in the respective years. A standardized questionnaire was used, containing closed questions on consumption of breast milk and other foods on the day before the survey, along with questions regarding the characteristics of the population.

RESULTS

The annual growth of the breastfeeding indicators was 2.1% for breastfeeding in the first hour of life (from 52.2% to 68.9%); 1.1% for breastfeeding among children aged 9 to 12 months (from 45% to 59.6%); and 0.8% for exclusive breastfeeding among infants younger than 6 months (from 36.9% to 47.4%). The median duration of exclusive breastfeeding increased from 52.3 to 84.3 days, and overall breastfeeding from 278 to 376 days. Some changes in the characteristics of the population were observed, which may have positively influenced the evolution of the breastfeeding indicators (better schooling level among the mothers, less use of dummies/pacifiers, and lower proportions of adolescent mothers), or negatively (greater proportions of primiparous mothers and cesarean deliveries, and lower frequency of births in Baby-Friendly Hospitals).

CONCLUSION

There were significant advances in breastfeeding indicators, although they are still far from ideal. Changes observed in population characteristics may have positively or negatively influenced this evolution.

Association between the Brazilian Breastfeeding Network implementation and breastfeeding indicators

OBJECTIVE

To estimate the association between the implementation of the Brazilian Breastfeeding Network and prevalence of breastfeeding in a medium-size city in southern Brazil.

METHODS

This was a cross-sectional study involving 405 children under 1 year who participated in the second phase of the multivaccination campaign in 2012. Children's consumption of food on the day before the interview was obtained through interviews with mothers or guardians. The manager and one health professional from every health facility that joined the Network were interviewed in order to investigate the process of implementation of this initiative. The association between prevalence of breastfeeding and exclusive breastfeeding and adherence to the Network implementation process was tested using Poisson regression with robust variance.

RESULTS

Multivariate analysis revealed that among the children assisted by health facilities who joined the Network and those attending services that did not adhere to this strategy, the prevalence of breastfeeding (74% and 70.4% among children under 1 year, respectively) and exclusive breastfeeding (43.3% and 38.1% among children under 6 months, respectively) did not differ significantly. Difficulties in implementing the Network, such as high turnover of professionals, not meeting the criteria for accreditation, and insufficient participation of tutors in the process were identified.

CONCLUSION

Contrary to the hypothesis of this study, there was no significant association between the implementation of the Brazilian Breastfeeding Network and prevalence of breastfeeding and exclusive breastfeeding in the studied city. It is possible that the difficulties found in implementing the Network in this city have influenced this result.

Problematic parent-infant relationships in two-parent families: prevalence and risk factors in a Brazilian neighborhood

Introduction: Although the quality of parent-child relationships is known to be associated with the offspring's mental health, little is known about the prevalence of problematic relationships in this scenario. This cross-sectional study aims to investigate the prevalence and risk factors of different types of early parent-infant relationships in a Brazilian population group. Methods: During 1 year, all families (n = 230) from an urban community of Porto Alegre, southern Brazil, with 4-month-old infants born in public hospitals were identified, and 148 were fully investigated by two family therapists. This study describes data on the 116 infants with two-parent families. Demographic, obstetric, and relational variables were collected through questionnaires and scales (Parent-Infant Relationship Global Assessment Scale, Global Assessment of Relational Functioning, and Self-Report Questionnaire). Prevalence ratios were calculated, and Poisson regression with robust variance was performed to adjust for covariates. Results: Almost 10% of mothers and 12% of fathers showed at least a significantly perturbed relationship with their 4-month-old infants. Inadequate mother-infant bonding coincided with evidence of paternal mental disorder, poor maternal social network, and discontinuation of breastfeeding at 4 months. A problematic father-infant relationship was associated with a dysfunctional couple relationship and with low infant birth weight. Conclusions: There is a high prevalence of early parent-child relationship problems, suggesting a need for health system interventions. Parent-infant relational problems are prevalent very early in life and more associated with other relational problems than with socioeconomic burden.

Early feeding practices and severe early childhood caries in four-year-old children from southern Brazil: a birth cohort study

The aim of this study was to investigate the relationship between feeding practices in the first year of life and the occurrence of severe early childhood caries (S-ECC) at 4 years of age. A birth cohort study (n = 500) was conducted in children who were born within the public health system in São Leopoldo, Brazil. Feeding practices were assessed using standardized methods at 6 and 12 months of age. A total of 340 children were examined at 4 years of age. S-ECC was defined as recommended by an expert panel for research purposes: ≥1 cavitated, missing or filled smooth surfaces in primary maxillary anterior teeth or d(1+) mfs ≥5. Poisson regression with robust variance was used in order to determine the early feeding practices which represent risk factors for the occurrence of S-ECC at 4 years of age. The multivariable model showed a higher adjusted risk of S-ECC for the following dietary practices at 12 months: breastfeeding ≥7 times daily (RR = 1.97; 95% CI = 1.45-2.68), high density of sugar (RR = 1.43; 95% CI = 1.08-1.89), bottle use for liquids other than milk (RR = 1.41; 95% CI = 1.08-1.86), as well as number of meals and snacks >8 (RR = 1.42; 95% CI = 1.02-1.97). Mother's education ≤8 years was also associated with the outcome. The present study identified early feeding practices which represent risk factors for caries severity in subsequent years. These findings may contribute to developing general and oral health interventions, with special attention to families with low maternal education.

Breastfeeding practice in the Brazilian capital cities and the Federal District: current status and advances

OBJECTIVES

To present the breastfeeding (BF) indicators obtained in the Second Survey on Prevalence of Breastfeeding in the Brazilian Capitals and the Federal District and to analyze their evolution from 1999 to 2008.

METHODS

A cross-sectional study was conducted in children younger than 1 year old who participated in the second phase of the multivaccination campaign in 2008. We used two-stage cluster sampling. The questionnaire consisted of closed questions, including data on consumption of breast milk, other types of milk, and other foods on the day prior to the survey. We analyzed the prevalence of BF in the first hour of life; exclusive BF in children younger than 6 months; BF in children aged 9 to 12 months; and medians of exclusive BF and BF. The time variation of BF was established by comparing the medians of exclusive BF and BF in 1999 and 2008.

RESULTS

We obtained data from 34,366 children. We found that 67.7% (95%CI 66.7-68.8) of the children were breastfed in the first hour of life; the prevalence of exclusive BF in children aged 0 to 6 months was 41% (95%CI 39.7-42.4), while the prevalence of BF in children aged 9 to 12 months was 58.7% (95%CI 56.8-60.7). There was an increase of 30.7 days in the median duration of exclusive BF and 45.7 days in the median of BF.

CONCLUSION

There was a significant improvement in the breastfeeding prevalence in the last decade. However, further efforts are required so that Brazil can reach BF rates compatible with the recommendations of the World Health Organization.

Effectiveness of an intervention to improve breastfeeding knowledge and attitudes among fifth-grade children in Brazil

This cluster-randomized trial evaluated the effectiveness and residual effect of an educational intervention to improve breastfeeding knowledge and attitudes among fifth grade children of both sexes in Brazil. Schools were considered clusters and analysis of variance was used to compare an intervention group (n = 298) and a control group (n = 253) regarding knowledge, perceptions, and beliefs about breastfeeding before and after the intervention, measured through a standardized 25-item, multiple-choice questionnaire. The scores in the intervention group improved significantly, with the effect lasting at least 3 months. The intervention had greater impact on girls and on students between 9 and 11 years of age when compared with boys and students between 12 and 17 years old and also between students from public schools. Results suggest that pro-breastfeeding interventions in schools improve breastfeeding knowledge and attitudes.

Fatores associados ao envolvimento do pai nos cuidados do lactente

OBJETIVO: Identificar fatores associados à falta de envolvimento ativo do pai nos cuidados de crianças aos quatro meses. MÉTODOS: Estudo transversal envolvendo famílias de 153 crianças aos quatro meses de vida, entrevistadas em suas casas por dois terapeutas de famílias. Além do envolvimento do pai nos cuidados do lactente foram examinadas características sociodemográficas, saúde mental dos pais (utilizando a escala Self Report Questionnaire-20 e avaliação com os critérios do Diagnostic and Statistical Manual of Mental Disorders-IV) e qualidade do relacionamento conjugal (usando a escala Global Assessment of Relational Functioning do Diagnostic and Statistical Manual of Mental Disorders-IV). Utilizou-se regressão de Poisson para avaliar a associação entre falta de envolvimento do pai nos cuidados do filho e variáveis selecionadas. A magnitude das associações foi estimada pela razão de prevalências. RESULTADOS: Os pais de 13% dos lactentes não tinham qualquer contato com seus filhos. Entre as famílias em que os pais coabitavam (78% do total), 33% dos pais relataram não participar ativamente nos cuidados de seus filhos. Relação conjugal problemática e mãe ser "do lar" mostraram-se associadas à falta de envolvimento dos pais nos cuidados do filho. CONCLUSÕES: É alta a prevalência de famílias nas quais o pai não tem envolvimento ativo no cuidado de seu filho, ocorrendo em especial quando a relação conjugal é problemática e a mãe não tem trabalho remunerado

Estudo exploratório sobre aleitamento materno entre escolares de quinta série do Ensino Fundamental

O estudo avaliou conhecimentos, percepções, crenças e vivências em relação ao aleitamento materno em 564 escolares, de ambos os sexos, da quinta série do Ensino Fundamental. O questionário usado continha 25 questões objetivas. Aplicou-se o teste de qui-quadrado e teste t, considerando a amostragem por conglomerado. Os escolares consideraram o leite materno o melhor alimento para o bebê, mas 60% optariam pela amamentação exclusiva de seus filhos. Menos de 20% responderam que a criança pode mamar até dois anos ou mais, aproximadamente ¼ acredita que o bebê deve começar a receber outros alimentos aos seis meses, e mais de 80% acredita que o consumo de chás e água é necessário. Detectaram-se as seguintes crenças: existência de leite fraco, chá é bom para cólicas, a amamentação deixa o peito caído, tamanho da mama influencia no volume de leite e a lactação deve ser interrompida com o aparecimento dos dentes. Destacaram também a participação do pai na amamentação, porém 70% relataram que ele pode ajudar dando mamadeira. Evidencia-se a necessidade de ações que promovam uma postura mais favorável à amamentação no Ensino Fundamental.

[The influence of breastfeeding technique on the frequencies of exclusive breastfeeding and nipple trauma in the first month of lactation]

OBJECTIVE

To investigate the influence of breastfeeding technique on the frequencies of exclusive breastfeeding and nipple trauma in the first month of lactation.

METHODS

We searched for unfavorable parameters of breastfeeding (five related to mother/baby positioning and three related to baby's latch on) in 211 mother-baby pairs in the maternity ward and at day 30, at home. We compared the frequencies of these parameters between mothers practicing or not exclusive breastfeeding at days 7 and 30, and between mothers with or without nipple trauma at the hospital.

RESULTS

The number of unfavorable parameters in the maternity ward was similar for mother-baby pairs practicing or not exclusive breastfeeding at day 7 and 30. However, at day 30, it was, on average, lower among those under exclusive breastfeeding, regarding positioning (1.7+/-1.2 vs 2.2+/-1.1; p = 0.009) as well as latch on (1.0+/-0.6 vs 1.4+/-0.6; p < 0.001). The number of unfavorable parameters related to latch on in the maternity ward was similar for women with or without nipple trauma, but women without trauma presented a higher number of unfavorable parameters related to positioning. (2.0+/-1.4 vs 1.4+/-1.2; p = 0.04).

CONCLUSIONS

The frequencies of exclusive breastfeeding in the first month and of nipple trauma were not influenced by the breastfeeding technique in the maternity ward, but there was an association between a better technique at day 30 and the practice of exclusive breastfeeding. New studies may help to elucidate whether an improvement in breastfeeding practices over time helps the maintenance of exclusive breastfeeding or whether the introduction of bottle-feeding determines a negative effect on breastfeeding.

Influência das avós na prática do aleitamento materno

OBJETIVO: Verificar a influência das avós na prática do aleitamento materno. MÉTODOS: Estudo prospectivo com 601 mães de recém-nascidos normais nascidos em hospital universitário na cidade de Porto Alegre, no Estado do Rio Grande do Sul. Os dados foram coletados na maternidade e nos domicílios, com um, dois, quatro e seis meses pós-parto, mediante entrevista com as mães. As informações sobre as avós foram obtidas na primeira visita ao domicílio. Regressão logística múltipla foi utilizada para testar associações entre variáveis relacionadas às avós e prevalências de amamentação. RESULTADOS: As seguintes variáveis mostraram associação significativa com interrupção do aleitamento materno exclusivo no primeiro mês: avós maternas e paternas que aconselhavam o uso de água ou chá (RC=2,2 e 1,8, respectivamente) e de outro leite (RC=4,5 e 1,9, respectivamente). Interrupção do aleitamento materno nos primeiros seis meses esteve associada com avós maternas e paternas que aconselhavam o uso de outro leite (RC=2,4 e 2,1, respectivamente). Contato não diário com a avó materna foi fator de proteção para a manutenção da amamentação aos seis meses. CONCLUSÕES: As avós podem influenciar negativamente na amamentação, tanto na sua duração quanto na sua exclusividade. Essa informação pode ser útil no planejamento de estratégias de promoção do aleitamento materno.

[Recommendations for the complementary feeding of the breastfed child]

OBJECTIVE

To present a review on the evidence that support the current recommendations for breastfed children feeding.

SOURCES OF DATA

An extensive bibliographic review of the topic was carried out. Articles selected in the MEDLINE and Lilacs databases, publications from national and international organizations, theses and dissertations were reviewed. Some key articles were also selected from the citations referred in other papers.

SUMMARY OF THE FINDINGS

New knowledge acquired about child feeding over the last 20 years have led to a significant change in the current feeding recommendations for breastfed children in relation to the prior recommendations. The current recommended nutritional needs are lower than the old recommendations, complementary food is introduced in a more precise age, around 6 months, and new methods are recommended for promoting the child's healthy eating. The new recommendations emphasize the health feeding practices which comprise both the adequate food quantity and quality, including care with food handling and preparation, feeding and storage practices, and the respect and adequacy to the cultural characteristics of each people.

CONCLUSIONS

The adequate complementary feeding of the breastfed child is critical for the optimal child growth and development. Therefore, it is an essential factor for both the populations food security and the development of nations. The health professionals ought to effectively pass on to mothers/care takers the new recommendations for promoting the healthy complementary feeding of the breastfed child. It is up to the governments to provide the adequate conditions for supporting such a promotion.

[Common problems during lactation and their management]

OBJECTIVE

To present an updated review on common problems associated with breastfeeding and their management.

SOURCE OF DATA

A comprehensive bibliographic review on the issue was performed by searching publications from the MEDLINE database and from national and international organizations. Books and some key articles cited in other sources were also selected.

SUMMARY OF THE FINDINGS

Several common problems that may arise during the breastfeeding period, such as breast engorgement, plugged milk duct, breast infection and insufficient milk supply, originate from conditions that lead the mother to inadequate empty the breasts. Incorrect techniques, not frequent breastfeeding and breastfeeding on scheduled times, pacifiers and food suppliers are important risk factors that can predispose to lactation problems. The adequate management of those conditions is fundamental, as if not treated they frequently lead to early weaning. There are specific measures that should be taken to empty the breasts effectively. Besides, the emotional support and actions that yield more comfort to the lactating mother can not be neglected.

CONCLUSIONS

Most common problems associated with breastfeeding can be prevented if the mother empties her breasts effectively. If they occur, they should be carefully and adequately approached, thus avoiding the early weaning resultant from painful and stressing situations the mother may face.

[Consumption of medicines among adolescent students: a concern]

OBJECTIVE

To study the prevalence of medicine consumption among adolescent students and to correlate it with school type (public or private), grades and school shift, age and gender of the students, education level of the parents and family habit of medicine consumption.

METHODS

This is a cross-sectional study with a representative sample of the school population attending high school in Porto Alegre: 1,281 students from 58 groups, distributed in proportional strata of public and private schools. The questionnaire was answered individually and anonymously by the students inside of the classroom. The students provided information about their consumption of medicines during the seven previous days, specifying the kind of medicine used. Descriptive analysis of the variables, linear association and multiple logistic regression tests were used.

RESULTS

The use of medicines occurred in 49.5% of the sample. The most consumed pharmacological groups were analgesics/anti-inflammatories and anti-gout agents (32.5% of the consumption), and hormones and similar (12.1%). Analgesics/antipyretics/anti-inflammatories and estrogens/progestogens were, respectively, the most consumed medicines of the pharmacological groups above mentioned. Aspirin was the most consumed analgesic substance. Female students (RC = 2.24), 17 years old or over (RC = 1.41), with low maternal education (RC = 1.40), and whose relatives have the habit of consuming medicines (RC = 1.39), presented increased risk for medicine consumption.

CONCLUSIONS

It was found that the consumption of medicines is high among school adolescents, especially among girls and older students. Family habit of consumption and low maternal education also favor the use of medicines.

Influence of Parental Mental Health on Early Termination of Breast-Feeding: a Case-Control Study

BACKGROUND

The WHO recommends exclusive breast-feeding for babies up to 6 months of age. The association between maternal mental health and breast-feeding duration is contradictory. This is a case-control study to investigate this association.

METHODS

153 families with 4-month-old babies from an urban area in southern Brazil were investigated: in 51 families, breast-feeding had being discontinued (cases); in 102, babies were being breast-fed (controls). Two researchers evaluated maternal and paternal mental health during home visits using semistructured interviews and scales.

RESULTS

Disorders were found in 59% of case mothers versus 48% of control mothers. Depression was the most prevalent disorder affecting both mothers and fathers. We did not identify a statistically significant association between maternal mental disorder at 4 months after delivery and early termination of breast-feeding. When the mother had mental problems during the first month after delivery, however, she was twice as likely to interrupt breast-feeding. Among the mothers with mental disorders during puerperium, 76% still had the problem 4 months postpartum. An association was observed between maternal and paternal mental health.

CONCLUSIONS

Parental mental health does not seem to be associated with breast-feeding at 4 months in this culture setting where most mothers have good family and social support for breast-feeding. Maternal mental disorders during puerperium, however, may negatively affect the duration of breast-feeding.

Couples' relationships and breastfeeding: is there an association?

One hundred fifty-three Brazilian families with 4-month-old infants--51 cases (breastfeeding had ceased) and 102 controls (breastfeeding maintained)--were recruited to verify if a problematic couple relationship is associated with early breastfeeding termination. The relationships of the 118 cohabiting couples were assessed by clinical interviews and the Global Assessment of Relational Functioning and Beavers-Timberlawn scales, examining marital and parental functions, parents' satisfaction with the quality of care each partner provided to their infants, mothers' opinions of paternal breastfeeding support, and interviewers' assessments of paternal breastfeeding support and involvement in the infants' care. The quality of a couple relationship was not associated with the interruption of breastfeeding before 4 months postpartum. However, a good couple relationship was associated with more paternal breastfeeding support (P < .01) and involvement in the infant's care (P < .0001).

The impact of breast reduction surgery on breastfeeding performance

The impact of reduction mammoplasty surgery on breastfeeding performance was measured comparing a group of 49 Brazilian women who had undergone breast reduction surgery using transposition techniques with 96 controls. As determined by survival analysis, the women who underwent reduction mammoplasty had a significantly shorter time of breastfeeding duration. The prevalence of exclusive breastfeeding at 1 and 4 months was 21% and 4%, respectively, for women with surgery, and 70% and 22%, respectively, for controls (P < .001). The prevalence of any breastfeeding at 1, 6, and 12 months was 58%, 16%, and 10% for women with mammoplasty, and 94%, 58%, and 42% for controls (P < .001). For women with surgery, the median duration of exclusive and any breastfeeding was 5 days and 2 months, respectively, and 3 months and 6 months for controls. The results of this study suggest that breast reduction surgery may have a negative impact on breastfeeding performance.
