Protective effect of breastfeeding against overweight can be detected as early as the second year of life: a study of children from one of the most socially-deprived areas of Brazil.

Millions of children live in Brazil's semi-arid region, one of the most socially-deprived areas of the country, where undernutrition co-exists with obesity as a consequence of the nutrition transition. There is evidence that childhood obesity predisposes adult obesity and, thus, that obesity should be prevented as early as possible. Some studies have shown that breastfeeding is a protective factor against overweight and obesity while other studies have not found this association. There have been few studies on this association in developing countries and of children below two years of age. The present study aimed to investigate whether children exposed to exclusive breastfeeding for ≥ 6 months showed a lower prevalence of overweight in the second year of life, based on a probability sample of 2,209 children (aged 12 to 24 months). The dependent variable was overweight, defined as weight-for-length z-scores of >2, based on the WHO 2006 standard while the independent variable was exclusive breastfeeding (≥ 6 months). The prevalence ratio (PR) and its 95% CI were estimated using Poisson regression with robust adjustment of variance. After adjusting for potential confounding factors (socioeconomic, demographic and health-related variables), children on exclusive breastfeeding for ≥ 6 months showed a lower prevalence of overweight (5.7% vs 9.1%, PR 0.62, 95% CI 0.45-0.89). It was found that exclusive breastfeeding for six months or more is a protective factor against overweight in children in the second year of life living in the Brazilian semi-arid region.

Pain assessment and management in the NICU: analysis of an educational intervention for health professionals / Avaliação e manejo da dor na UTI neonatal: análise de uma intervenção educativa para os profissionais de saúde

OBJECTIVE: to study the perception of a Neonatal Intensive Care team on pain assessment and management before and after an educational intervention created and implemented in the unit. METHODS: intervention study developed as action research, in three phases. In Phase 1, a quantitative study was performed to identify how professionals perceive pain management in the unit. In Phase 2, an educational intervention was carried out, using the Operational Group (OG), which defined strategies to be adopted to seek improvements in pain assessment and management. In Phase 3, the initial questionnaire was reapplied to assess professionals' perceptions about the subject after the intervention. All professionals directly working in newborn care were included. RESULTS: the perception of professionals about pain management and assessment in the unit showed a statistically significant difference between the two phases of research, highlighting the increase in frequency of reference for evaluation and use of some method of pain relief procedures for most analyzed procedures. Participation in training (one of the strategies defined by the operational group) was reported by 86.4% of the professionals. They reported the use of scales for pain assessment, established by the protocol adopted in the service after the intervention, with a frequency of 94.4%. Changes in pain assessment and management were perceived by 79.6% of the participants. CONCLUSION: the professionals involved in the educational intervention observed changes in pain management in the unit and related them to the strategies defined and implemented by the OG. .

Promotion of exclusive breast-feeding at scale within routine health services: impact of breast-feeding counselling training for community health workers in Recife, Brazil.

OBJECTIVE: Breast-feeding counselling has been identified as the intervention with the greatest potential for reducing child deaths, but there is little experience in delivering breast-feeding counselling at scale within routine health systems. The study aim was to compare rates of exclusive breast-feeding associated with a breast-feeding counselling intervention in which community health agents (CHA) received 20 h of training directed at counselling and practical skills with rates pre-intervention when CHA received 4 h of didactic teaching. DESIGN: Cross-sectional surveys of breast-feeding practices were conducted pre- and post-intervention in random samples of 1266 and 1245 infants aged 0-5.9 months, respectively. SETTING: Recife, Brazil, with a population of 2 million. SUBJECTS: CHA (n 1449) of Brazil's Family Health Programme were trained to provide breast-feeding counselling at home visits. RESULTS: Rates of exclusive breast-feeding improved when CHA were trained to provide breast-feeding counselling and were significantly higher by 10-13 percentage points at age 3-5.9 months when compared with pre-intervention rates (P < 0.05). Post-intervention point prevalence of exclusive breast-feeding for infants aged <4 months was 63% and for those aged <6 months was 50%. CONCLUSIONS: Multifunctional CHA were able to deliver breast-feeding counselling at scale within a routine health service and this was associated with a significant increase in rates of exclusive breast-feeding. The study reinforces the need to focus training on counselling and practical skills; a key component was an interactive style that utilized the knowledge and experience of CHA. The findings are relevant to the call by international organizations to scale up breast-feeding counselling.

Fatores de risco para mortalidade neonatal, com especial atenção aos fatores assistenciais relacionados com os cuidados durante o período pré-natal, parto e história reprodutiva materna / Determinants of neonatal death with emphasis on health care during pregnancy, childbirth and reproductive history

OBJETIVO: Identificar fatores de risco para mortalidade neonatal, com especial atenção aos fatores assistenciais relacionados com os cuidados durante o período pré-natal, parto e história reprodutiva materna. MÉTODOS: Trata-se de um estudo caso-controle realizado em Maceió, Nordeste do Brasil. A amostra consistiu de 136 casos e 272 controles selecionados em bancos de dados oficiais brasileiros. Os casos foram todos os recém-nascidos que morreram antes de completar 28 dias de vida, selecionados no Sistema de Informações sobre Mortalidade, e os controles foram os sobreviventes neste período, selecionados no Sistema de Informações sobre Nascidos Vivos, por sorteio aleatório entre as crianças nascidas na mesma data do caso. Entrevistas domiciliares foram realizadas com as mães. RESULTADOS: A análise de regressão logística identificou como fatores determinantes para a morte no período neonatal mães com história de filhos anteriores que morreram no primeiro ano de vida (OR = 3,08), o internamento durante a gestação (OR = 2,48), o pré-natal inadequado (OR = 2,49), a não realização de ecografia durante o pré-natal (OR = 3,89), a transferência de recém-nascidos para outra unidade após o nascimento (OR = 5,06), os recém-nascidos internados em UTI (OR = 5,00) e o baixo peso ao nascer (OR = 2,57). Entre as condições socioeconômicas, observou-se uma maior chance para mortalidade neonatal em residências com menor número de moradores (OR = 1,73) e com ausência de filhos menores de cinco anos (OR = 10,10). CONCLUSÕES: Vários fatores que se mostraram associados à mortalidade neonatal neste estudo podem ser decorrentes de assistência inadequada ao pré-natal, ao parto e ao recém-nascido, sendo, portanto, passíveis de serem modificados.

OBJECTIVE: To identify risk factors for neonatal mortality, focusing on factors related to assistance care during the prenatal period, childbirth, and maternal reproductive history. METHODS: This was a case-control study conducted in Maceió, Northeastern Brazil. The sample consisted of 136 cases and 272 controls selected from official Brazilian databases. The cases consisted of all infants who died before 28 days of life, selected from the Mortality Information System, and the controls were survivors during this period, selected from the Information System on Live Births, by random drawing among children born on the same date of the case. Household interviews were conducted with mothers. RESULTS: The logistic regression analysis identified the following as determining factors for death in the neonatal period: mothers with a history of previous children who died in the first year of life (OR = 3.08), hospitalization during pregnancy (OR = 2.48), inadequate prenatal care (OR = 2.49), lack of ultrasound examination during prenatal care (OR = 3.89), transfer of the newborn to another unit after birth (OR = 5.06), admittance of the newborn at the ICU (OR = 5.00), and low birth weight (OR = 2.57). Among the socioeconomic conditions, there was a greater chance for neonatal mortality in homes with fewer residents (OR = 1.73) and with no children younger than five years (OR = 10.10). CONCLUSION: Several factors that were associated with neonatal mortality in this study may be due to inadequate care during the prenatal period and childbirth, and inadequate newborn care, all of which can be modified.

Characteristics and factors associated with health care in children younger than 1 year with very low birth weight.

OBJECTIVES: To identify the characteristics of health care in infants with very low birth weight during the first year of life and the factors associated with this care. METHODS: This was a descriptive study with an analytical component conducted in the city of Maceió, Northeastern Brazil, with a sample of 53 children with a median age of five months at the time of the interview, and their mothers. The mothers were interviewed at home regarding socioeconomic and demographic data and health care provided for the child. Health care was assessed through an index using 16 variables related to the recommended actions for this type of care. RESULTS: Multivariate linear regression analysis showed that maternal education and family income were the variables that best explained the health care index variation (18.9%), followed by parity (6.6%), and breastfeeding at the time of the interview (6.9%). CONCLUSIONS: Considering that families with lower socioeconomic status, women with a higher number of children, and women who did not breastfeed were factors associated with poor health care of children born with very low birth weight, these variables should be included in measures of public health planning.

Características e fatores associados à assistência à saúde de crianças menores de um ano com muito baixo peso ao nascer / Characteristics and factors associated with health care in children younger than 1 year with very low birth weight

OBJETIVOS: Identificar as características da assistência à saúde de lactentes com muito baixo peso ao nascer no primeiro ano de vida e os fatores associados a esta atenção. MÉTODOS: Estudo descritivo com componente analítico foi realizado na cidade de Maceió, Nordeste do Brasil, com uma amostra de 53 crianças com idade mediana de cinco meses na época da entrevista, e suas respectivas mães. As mães foram entrevistadas no domicílio,quanto às condições socioeconômicas, demográficas e de assistência à saúde da criança. A atenção à saúde foi avaliada com a elaboração de um índice utilizando 16 variáveis relacionadas às ações preconizadas para esta assistência. RESULTADOS: A análise de regressão linear multivariada mostrou que a escolaridade materna e a renda familiar foram as variáveis que, juntas, melhor explicaram a variação do Índice de Atenção à Saúde (18,9%), seguidas da paridade (6,6%) e da prática do aleitamento materno na época da entrevista (6,9%). CONCLUSÕES: Considerando que as famílias com piores condições socioeconômicas e as mulheres com maior número de filhos e que não amamentaram foram os fatores associados a uma assistência inadequada à saúde de crianças nascidas com muito baixo peso, os mesmos deveriam ser contemplados nas ações de planejamento da saúde pública.

Periodontitis as a risk factor for preeclampsia.

BACKGROUND: Periodontitis is an inflammatory process caused by a specific group of microorganisms, resulting in the destruction of the tooth-supporting tissue and the resorption of the alveolar bone. Therefore, periodontitis has been considered a risk factor for preeclampsia because infection is one of the factors involved in the etiology and pathogenesis of preeclampsia. The aim of the present study is to determine whether periodontitis is a risk factor for preeclampsia and to identify other possible risk factors. METHODS: A case-control study was performed with 574 puerperae under care at the university hospital at the Universidade Federal de Pernambuco in the city of Recife, Brazil. Data collection was preceded by a training exercise and a pilot study. Biologic and socioeconomic data were collected along with medical and dental records. A periodontal examination was performed on all dental elements to determine probing depth and gingival recession. The association between periodontitis and preeclampsia was first adjusted for the variables within each block, and adjusted for the variables of all blocks in the final multivariate model. RESULTS: The multivariate logistic regression analysis showed that, after adjustment for other risk factors, periodontitis remained an independent risk factor for preeclampsia (adjusted odds ratio [OR] = 8.60, confidence interval [CI] = 3.92 to 18.88, P < 0.001 and adjusted OR = 2.03, 95% CI = 1.43 to 2.90, P < 0.001, when using the Centers for Disease Control and Prevention/American Academy of Periodontology definition). CONCLUSION: The results suggest that within the population studied, periodontitis was a risk factor for preeclampsia.

Maternal periodontitis as a risk factor for prematurity.

BACKGROUND: The aim of this study was to investigate maternal periodontitis associated with prematurity. METHODS: We carried out a case-control study including 718 puerperae who experienced a spontaneous delivery: 360 cases (premature) and 358 controls (full-term). Sociodemographic, obstetric, prenatal, perinatal and periodontal data were obtained within 48 h after delivery. Periodontitis was defined as probing depth ≥ 4 mm and attachment loss ≥ 3 mm at same site, for ≥ 4 teeth. RESULTS: Periodontitis was associated with prematurity (odds ratio 6.95; confidence interval 3.69-13.09). Prematurity was associated with maternal age < 20 years, family income < one minimum salary, maternal schooling < 8 years, premature birth history, premature membrane rupture, ruptured membranes > 24 h, smoking, urinary tract infection, leukorrhea, pre-eclampsia, prenatal consultations < 3 and precarious housing. After multivariate confounder adjustments, periodontitis remained independently associated with prematurity (odds ratio 6.05; confidence interval 3.01-12.16). CONCLUSIONS: Periodontitis is strongly associated with prematurity, indicating necessity for regular periodontal investigation and treatment during pregnancy.

Influence of breastfeeding type and maternal anemia on hemoglobin concentration in 6-month-old infants.

OBJECTIVE: To verify the influence of breastfeeding type and of maternal anemia on hemoglobin concentration in 6-month-old infants. METHODS: This was a cross-sectional study nested in a community-based, randomized and controlled intervention study that aimed to prolong the duration of exclusive breastfeeding during the first 6 months of life. This study was conducted in four towns in the Brazilian state of Pernambuco and newborn infants were recruited from March to August of 2001. The hemoglobin concentrations of 330 mothers and infants were assayed and type of breastfeeding was assessed 6 months after delivery. Multivariate linear regression analysis was used to identify factors that independently contributed to the infants' hemoglobin concentration. RESULTS: The type of feeding had no influence on the hemoglobin concentration in the sample as a whole, however, there was a significant difference when the "exclusive + predominant breastfeeding" subset of infants was analyzed, with the children of anemic mothers exhibiting a reduction of 0.7g/dL in median hemoglobin. Mothers' hemoglobin level, type of flooring at home, type of delivery, and birthweight all significantly contributed to the variation in the infants' hemoglobin concentration. CONCLUSIONS: In contrast with type of breastfeeding, maternal anemia did have an influence on the hemoglobin levels of 6-month-old infants, even when only children on "exclusive + predominant breastfeeding" were analyzed. These findings highlight the need to prevent maternal anemia before conception, during pregnancy and throughout lactation.

Influência do tipo de aleitamento materno e da presença de anemia na mãe na concentração de hemoglobina aos 6 meses de idade / Influence of breastfeeding type and maternal anemia on hemoglobin concentration in 6-month-old infants

Objetivo: Verificar a influência do tipo de aleitamento materno e da presença de anemia na mãe no nível de hemoglobina de lactentes aos 6 meses de idade. Métodos: Estudo transversal, aninhado em estudo de intervenção de base comunitária, randomizado, controlado, que objetivou aumentar a duração do aleitamento materno exclusivo nos primeiros 6 meses de vida. O estudo foi realizado em quatro cidades do estado de Pernambuco, sendo os recém-nascidos recrutados no período de março a agosto de 2001. Seis meses após o parto, avaliou-se a concentração da hemoglobina de 330 mães/lactentes e o tipo de aleitamento. A identificação dos fatores que, de modo independente, contribuíram na concentração de hemoglobina das crianças foi realizada utilizando análise de regressão linear multivariada. Resultados: O tipo de aleitamento não influenciou a concentração de hemoglobina na amostra como um todo. No entanto, ao se analisar o grupo de crianças em aleitamento exclusivo/predominante, verificou-se uma diferença significante na mediana da hemoglobina de 0,7 g/dL em detrimento das filhas de mães anêmicas. A hemoglobina materna, o tipo de piso da residência, o tipo de parto e o peso ao nascer contribuíram significantemente na variação da concentração de hemoglobina das crianças. Conclusões: Ao contrário do observado em relação ao tipo de aleitamento materno, a anemia materna exerceu influência sobre os valores de hemoglobina de lactentes aos 6 meses, mesmo quando consideradas apenas as crianças em aleitamento exclusivo/predominante, apontando para a necessidade de prevenção da anemia materna antes da concepção, durante a gravidez e na lactação.

[The impact of training based on the Baby-Friendly Hospital Initiative on breastfeeding practices in the Northeast of Brazil]. / Impacto de treinamento baseado na Iniciativa Hospital Amigo da Criança sobre práticas relacionadas à amamentação no interior do Nordeste.

OBJECTIVE: To evaluate the impact of training based on the Baby Friendly Hospital Initiative on breastfeeding practices in maternity wards and during the first 6 months of life. METHODS: Ninety percent of nursing auxiliaries and midwives were trained at two institutions (A and B) in Palmares, Pernambuco state. Three hundred and thirty-four mothers were interviewed within the first 48 hours and 10 days after childbirth to evaluate breastfeeding practices at the maternities and fulfillment of steps 4 through 10 of the Baby Friendly Hospital Initiative. A subset of 166 mothers received seven home visits to evaluate breastfeeding practices throughout the first 6 months of life and to compare results with those of a cohort study conducted in the area in 1998. RESULTS: The performance of maternity B was significantly better than that of maternity A, from steps 4 to 10 and also in terms of exclusive breastfeeding and offering less water or tea to infants (p < 0.001). The comparison with a previous cohort study demonstrated an improvement in breastfeeding practices at the maternity wards and an increase of exclusive breastfeeding prevalence (from 21.2 to 70%), during the first 48 hours after delivery and throughout the first six months. CONCLUSIONS: The training promoted partial change to some practices related to breastfeeding, having a positive effect on total and exclusive breastfeeding at the maternity wards. However, there was no significant change to these practices over the first 6 months of life, suggesting the need for effective interventions to support exclusive breastfeeding in the health sector and in the community.

Impacto de treinamento baseado na Iniciativa Hospital Amigo da Criança sobre práticas relacionadas à amamentação no interior do Nordeste / The impact of training based on the Baby-Friendly Hospital Initiative on breastfeeding practices in the Northeast of Brazil

OBJETIVO: Avaliar o impacto de treinamento baseado na Iniciativa Hospital Amigo da Criança sobre práticas relacionadas à amamentação na maternidade e freqüências de aleitamento materno nos primeiros 6 meses de vida. MÉTODOS: Foram treinadas 90 por cento das auxiliares de enfermagem e parteiras de duas maternidades (A e B) de Palmares (PE). Foram entrevistadas 334 mães nas primeiras 48 horas e 10 dias após o parto, para avaliar práticas que estimulam a amamentação nas maternidades e o cumprimento do quarto ao 10° passo da Iniciativa Hospital Amigo da Criança. Uma subamostra de 166 mães recebeu sete visitas domiciliares, para avaliar as freqüências do aleitamento materno nos 6 primeiros meses de vida. Os resultados foram comparados com os de estudo de coorte realizado na área em 1998. RESULTADOS: O desempenho da maternidade B foi melhor que o da maternidade A quanto às práticas que promovem o aleitamento materno relacionadas aos passos avaliados e quanto às freqüências de amamentação exclusiva. Comparação com coorte histórica evidenciou melhora nas práticas relacionadas à amamentação nas maternidades e aumento nas freqüências do aleitamento materno exclusivo (de 21,2 para 70 por cento), nas primeiras 48 horas após o parto e durante os 6 primeiros meses de vida. CONCLUSÕES: O treinamento promoveu mudanças parciais em algumas práticas relacionadas à amamentação, repercutindo de forma positiva sobre as freqüências de aleitamento materno e aleitamento materno exclusivo nas maternidades. Contudo, não houve mudanças expressivas nessas freqüências ao longo dos 6 meses de vida, sugerindo a necessidade de intervenções efetivas no apoio ao aleitamento exclusivo nos serviços de saúde e na comunidade.
