Determinants of using pacifier and bottle feeding

OBJECTIVE To analyze the factors associated with the use of pacifiers and/or bottle feeding in infants aged under one year.METHODS This is a cross-sectional study with 34,366 children and using data from the database of the 2nd Nationwide Survey of Breastfeeding Prevalence performed in the Brazilian capitals and Federal District in 2008. Cluster sampling was used. The questionnaire included questions about the use of artificial nipples in the last 24 hours. The analysis considered three outcomes: exclusive use of pacifier, exclusive use of bottle feeding, and use of artificial nipples (pacifier and bottle feeding). Prevalence ratios were obtained using Poisson regression with robust variance following a hierarchical model.RESULTS The following factors were associated with exclusive use of the pacifier: mother working outside the home, primiparity, child was not breastfed within the first hour, and child had consumed tea on the first day at home. The following factors were associated with exclusive use of bottle feeding: mother working outside the home, primiparity, low birth weight, child not breastfed within the first hour, and child had consumed milk formula and tea on the first day at home. The following factors were associated with use of artificial nipples (pacifier and bottle feeding): mother working outside the home, primiparity, cesarean delivery, the male gender, low birth weight, born in a hospital not accredited as “baby friendly”, required health baby monitoring in the Primary Health Care Unit (PR = 0.91), and child had consumed milk formula, water, or tea on the first day at home.CONCLUSIONS This study identified profiles of exclusive users of pacifiers, bottle feeding, and both. The provided information can guide preventive practices for child health.

Pacifier : construção e aplicação de um programa para pais nos cuidados de saúde primários

Este trabalho teve como objetivo fundamental a construção, aplicação e avaliação dos efeitos de um programa de educação parental universal, numa vertente preventiva, designado como – Pacifier – visando a sua implementação nos Cuidados de Saúde Primários, a pais de crianças dos 0 aos 6 meses e com carácter domiciliário. Foi construído com base numa revisão da literatura e práticas baseadas em evidência sobre parentalidade positiva e programas de educação parental e posteriormente aplicado a quatro mães e dois pais – dois casais e duas mães –, sendo que os efeitos foram avaliados de acordo com um modelo de estudos de caso múltiplos, constituídos por quatro famílias. Neste sentido, de modo a medir os objetivos que definimos para o programa, realizámos uma avaliação inicial e final com os instrumentos adaptados Sentido de Competência Parental e Inventário sobre o Conhecimento de Desenvolvimento Infantil. Ainda incluímos um questionário final relativo à Satisfação dos Pais com o Programa. No que respeita aos resultados, nos quatro estudos de caso verificaram-se melhorias nos resultados de ambos os instrumentos aplicados, o que nos permite considerar que o programa foi eficaz e melhorou o sentido de competência parental assim como o conhecimento do desenvolvimento infantil nestes pais. Por último, os pais mostraram uma grande satisfação com o programa.

Administration of Bifidobacterium animalis subsp. lactis BB-12 and xylitol with a novel pacifier in early childhood

Probiotic bifidobacteria are used in the prevention and treatment of childhood diseases. On the other hand, these bacteria are also connected to dental caries. The purpose of the present work was to test a food supplement containing Bifidobacterium animalis subsp. lactis BB-12 (B. lactis BB-12) and xylitol, and to investigate its health effects, properties and safety when used in a novel pacifier in early childhood. In a double-blind, placebo-controlled trial, newborn infants (n=163) were assigned randomly to receive B. lactis BB-12, xylitol, or sorbitol from the age of 1– 2 monthsto 2 years with a pacifier or a spoon. Children were followed up to four years of age. A part of the parents participating in the clinical trial evaluated the feasibility of the novel administration method. The pattern of tablet release from the pouch of the pacifier was tested in adults. The food supplement tablet containing B. lactis BB-12 and xylitol could be delivered in a safe and controlled way with the novel pacifier. The early administration of B. lactis BB-12 did not result in permanent oral colonization of this probiotic or affect the colonization of mutans streptococci in early childhood. Moreover, B. lactis BB-12 did not increase the occurrence of caries. Controlled administration of B. lactis BB-12 significantly reduced the incidence of respiratory infections during the first eight months of life in a Finnish population with breastfed infants. To conclude, administration of B. lactis BB-12 in early childhood is safe with regard to the future dental health of the child. In addition, B. lactis BB-12 may add to the protection against respiratory infections provided by human breast milk in infancy.

Retention mucocele on the lower lip associated with inadequate use of pacifier

Mucocele forms because of salivary gland mucous extravasation or retention and is usually related to trauma in the area of the lower lips. Ruptured ducts release the mucous that accumulates into adjacent tissues, leading to swelling. This report describes a large mucocele involving the lower lip, which was produced in a child by incorrect use of a pacifier. A few important concepts are discussed to help clinicians in the diagnosis and treatment of this pathology. © 2010 Dermatology Online Journal.

Hábitos de sucção não nutritiva em crianças pré-escolares

OBJETIVO: Verificar a prevalência e os fatores associados aos hábitos de sucção não nutritiva em crianças pré-escolares matriculadas em creches e pré-escolas de Natal (RN). MÉTODOS: Foi conduzido um estudo transversal com 1.190 crianças de ambos os sexos na faixa etária de 3 a 5 anos, matriculadas em creches e pré-escolas de Natal. Não foram incluídas no estudo crianças com fendas labiopalatinas, desordens temporomandibulares, ou aquelas submetidas a tratamento ortodôntico e/ou ortopédico; também não fizeram parte da amostra instituições de ensino especializadas em crianças portadoras de deficiência. Utilizou-se um questionário estruturado, respondido pelos pais ou responsável, com dados sobre a instituição, sexo e idade das crianças, escolaridade dos pais e questões relacionadas aos hábitos. A análise dos dados foi realizada através do teste do qui-quadrado e a regressão logística. RESULTADOS: Obteve-se prevalência de 40,2% de hábitos de sucção não nutritiva, dos quais 27,7% eram de sucção de chupeta e 12,5% de dedo. Os hábitos de sucção apresentaram maior percentual para o sexo feminino, destacando-se a sucção de dedo (p = 0,02); em crianças com menos idade destacou-se a sucção de chupeta (p = 0,0006). Observou-se maior frequência de sucção de chupeta e de dedo, respectivamente, para o nível superior (p < 0,05) e fundamental (p < 0,05) de escolaridade dos pais. A regressão logística demonstrou que a menor idade dos indivíduos (p = 0,033) e o nível médio de escolaridade dos pais (p = 0,035) são fatores independentes para a persistência dos hábitos. CONCLUSÃO: Verificou-se uma alta prevalência de realização dos hábitos de sucção não nutritiva, apresentando como fatores de destaque a menor idade das crianças e o nível médio de escolaridade dos pais.

Bottle feeding, increased overjet and Class 2 primary canine relationship: is there any association?

The aim of this study was to investigate the association between bottle feeding and prevalence rates of increased overjet and Class 2 primary canine relationship. The sample consisted of 911 children (461 boys, 450 girls) aged 3 (13.9%), 4 (40.8%), 5 (34%) and 6 (11.3%) years, with complete primary dentition. Information about nutritive and nonnutritive (pacifier and/or digit) sucking habits was collected through questionnaires. Three calibrated dentists (κ: 0.9-1.0 and Rs > 0.90) performed the clinical assessments. The children were divided into four groups: G1 - not bottle-fed; G2 - exclusively bottle-fed; G3 - breast- and bottle-fed, bottle feeding ceased before 3 years of age; and G4 - breast- and bottle-fed, bottle feeding ceased between 3 and 4 years of age. Associations between nutritive and nonnutritive sucking behaviors and the malocclusions studied were analyzed by multiple binary logistic regression (α= 0.05). The frequencies of increased overjet were: 25.3% (G1), 38.8% (G2), 39.2% (G3) and 47.8% (G4). The percentages of Class 2 canine relationship were: 27.9% (G1), 48.8% (G2), 43.4% (G3) and 43% (G4). No significant effect of bottle feeding was found. The chances of diagnosing increased overjet (O.R. = 4.42, p < 0.001) and Class 2 canine relationship (O.R. = 4.02, p < 0.001) were greater for children with pacifier and/or digit-sucking habits, compared to those without a history of nonnutritive sucking behavior. It may be suggested that bottle feeding alone is not directly associated with higher prevalence rates of increased overjet and Class 2 canine relationship in the primary dentition.

Exclusive Breastfeeding in Southern Brazil: Prevalence and Associated Factors

Background: Worldwide strategies have been conducted in order to guarantee longer periods of exclusive breastfeeding for most children, especially those from developing countries. The evaluation of infant feeding practices and the identification of weaning risk factors are essential for public health policy planning. Methods: This cross-sectional study was carried out in Joinville, the biggest city of Santa Catarina State in the southern Brazilian region. The caregivers of children under 1 year of age were systematically selected for interview in previously drawn immunization units during the 2005 National Vaccination Campaign. A structured questionnaire was applied for collection of infant, maternal, and healthcare variables. A 24-hour food recall survey was included in order to evaluate infant feeding practices. Descriptive statistic analysis on breastfeeding prevalence and Poisson regression analysis of risk factors for discontinuing exclusive breastfeeding for infants up to 6 months of age were performed. Results: Caregivers of 1,470 infants were interviewed. The feeding inquiry showed an overall rate of breastfeeding of 72.5% and a frequency of exclusive breastfeeding of 43.7% and 53.9% among infants younger than 6 and 4 months of age, respectively. The findings associated with the interruption of exclusive breastfeeding for infants up to 6 months were: higher infant age (P < 0.001), pacifier use (P < 0.001), and lower maternal educational level (P = 0.013). Conclusions: In developing countries, specific strategies must be created for the delivery of information about breastfeeding and the effect of pacifier use, especially for less educated women.

Association between breastfeeding duration and non-nutritive sucking habits

Objective To evaluate the relationship between breastfeeding duration and the prevalence of non-nutritive Sucking habits in children with deciduous dentition. Method A cross-sectional survey was conducted on the mothers of 551 children aged 3 to 6 years, randomly selected from public pre-schools in Sao Paulo, Brazil. Mothers were asked to complete a questionnaire that included items regarding their children`s age, gender, race, method and duration of infant feeding, as well as pacifier use and/or digit-sucking habits. According to the answers pertinent to the method and duration of infant feeding, children were assigned to five groups: 1 - never breastfed, 2 - breastfed for a period shorter than 3 months of life, 3 - breastfed for 3 to 6 months, 4 - breastfed for 6 to 9 months, and 5 - breastfed for 9 months or longer. Data were submitted to the Fisher`s exact test with Bonferroni correction for multiple comparisons to analyse possible associations between breastfeeding duration period categories and non-nutritive sucking behaviours. Results Pacifier use frequency was high in groups 1, 2, 3 and 4 (85%, 87.6%, 78% and 70%, respectively), in comparison with that in group 5 (38.6%). The prevalence of non-nutritive sucking habits was significantly reduced in children who were breastfed for nine months or longer (p=0.000). There were no statistically significant differences in the frequencies of pacifier use and/or digit-sucking habits between genders, regardless of the breastfeeding duration period. Conclusion Children aged 3-6 years who were breastfed for nine months or longer had a lower prevalence of non-nutritive sucking habits.

The effect of high-pass filtering on TEOAE in 2-month-old infants

The aim of the present study was to investigate the effect of high-pass filtering on TEOAE obtained from 2-month-old infants as a function of filter cut-off frequency, activity states and pass/fail status of infants. Two experiments were performed. In Experiment 1, 100 2-month-old infants (200 ears) in five activity states (asleep, awake but peaceful, sucking a pacifier, feeding, restless) were tested by use of TEOAE technology. Five different filter conditions were applied to the TEOAE responses post hoc. The filter conditions were set at 781 Hz (default setting), 1.0, 1.2, 1.4 and 1.6 kHz. Results from this experiment showed that TEOAE parameters, such as whole-wave reproducibility (WR) and signal-to-noise ratio (SNR) at 0.8 kHz and 1.6 kHz, changed as a function of the cut-off frequency. The findings suggest that the 1.6 kHz and 1.2 kHz filter conditions are optimal for WR and SNR pass/fail criteria, respectively. Although all infant recordings appeared to benefit from the filtering, infants in the noisy states seemed to benefit the most. In Experiment 2, the high-pass filtering technique was applied to 23 infants (35 ears) who apparently failed the TEOAE tests on initial screening but were subsequently awarded a pass status based on the results from a follow-up auditory brainstem response (ABR) assessment. The findings showed a significant decrease in noise contamination of the TEOAE with a corresponding significant increase in WR. With high-pass filtering at 1.6 kHz, 21/35 ears could be reclassified into the pass category.

Interação mãe-bebê e uso de chupeta no contexto do nascimento pré-termo : cultura, representações sociais e processos proximais

Objetivo: Investigar a avaliação de mães de recém-nascidos pré-termo (RNPT) egressos de unidades de terapia intensiva neonatal (UTIN) quanto à interação mãe-bebê e uso de chupeta nos primeiros dois anos. Método: O planejamento do estudo longitudinal foi baseado na Teoria Bioecológica do Desenvolvimento Humano, com foco nos processos proximais (PP), utilizando entrevistas gravadas com 62 mães de RNPT no contexto da UTIN e 33 aos seis, 12, 18 e 24 meses de idade do bebê, considerando Grupo-A (chupeta) e Grupo-B (não usou chupeta). Resultados: A vivência em UTIN foi considerada evento impactante na vida das mães, mas expectativas futuras para a relação mãe-bebê foram positivas. A tentativa de oferta da chupeta foi 96,2% e seu uso aos seis meses foi 50% (n=52), significativamente associado com prematuridade pela relação peso/idade-gestacional (p-valor=0,044), dificuldades para estabelecer aleitamento materno exclusivo (AME) (p=0,012) e primiparidade (p=0,02). Apresentaram relação com menor frequência de chupeta: AME ≥3 meses (p=0,026) e tempo de aleitamento materno ≥6 meses. A chupeta configurou-se como uma das representações sociais sobre objetos de bebê, elaboradas pelas participantes aos 12 meses de idade do bebê. Características de temperamento calmo/tranquilo da mãe foram mais frequentes no Grupo-A e o temperamento nervoso/agitado/irritado no Grupo-B (p-valor=0,041). No Grupo-A predominou o temperamento do bebê calmo/fácil-de-cuidar/independente, enquanto no Grupo-B as características de temperamento agitado/bagunceiro/teimoso/agressivo (p-valor=0,026), associado também à necessidade de várias tentativas de oferta da chupeta (p-valor=0,006). No Grupo-A, o número de pessoas para apoio social foi uma ou duas (77,8%), enquanto no Grupo-B foram três a sete (66,7%), p-valor=0,001. A contribuição da chupeta como auxiliar nos PP foi indiferente para mães que controlavam o hábito, enquanto o uso irrestrito facilitava a resolução do choro, liberando a mãe para outras tarefas, atuando como limitador dos PP. A análise da evolução e complexidade dos PP demonstrou não haver interferência pelo uso da chupeta, tendo sido mais efetivos quando as mães tinham maior escolaridade e nas classes econômicas A e B. Conclusão: Aspectos culturais influenciaram na oferta da chupeta, mas sua aceitação ocorreu principalmente em RNPT pequeno para idade gestacional, diante das dificuldades para AME, menor extensão do apoio social e temperamento do bebê calmo/fácil-de-cuidar/independente, também associado à aceitação mais fácil da chupeta. O uso irrestrito da chupeta demonstrou atuar como limitador dos processos proximais.

Effects of breastfeeding and sucking habits on malocclusion in a birth cohort study

OBJECTIVE: To estimate the prevalence of malocclusion and to examine the effects of breastfeeding and non-nutritive sucking habits on dentition in six-year-old children. METHODS: A cross-sectional study was carried out nested into a birth cohort conducted in Pelotas, Southern Brazil, in 1999. A sample of 359 children was dentally examined and their mothers interviewed. Anterior open bite and posterior cross bite were recorded using the Foster & Hamilton criteria. Information regarding breastfeeding and non-nutritive sucking habits was collected at birth, in the first, third, sixth and 12th months of life, and at six years of age. Control variables included maternal schooling and child's birthweight, cephalic perimeter, and sex. Data were analyzed by Poisson regression. RESULTS: Prevalence of anterior open bite was 46.2%, and that of posterior cross bite was 18.2%. Non-nutritive sucking habits between 12 months and four years of age and digital sucking at age six years were the main risk factors for anterior open bite. Breastfeeding for less than nine months and regular use of pacifier between age 12 months and four years were risk factors for posterior cross bite. Interaction between duration of breastfeeding and the use of pacifier was identified for posterior cross bite. CONCLUSIONS: Given that breastfeeding is a protective factor for other diseases of infancy, our findings indicate that the common risks approach is the most appropriate for the prevention of posterior cross bite in primary or initial mixed dentition.
