Use of screens and intake of unhealthy food among children and adolescents: association with physical activity in a cross-sectional study.

BACKGROUND: The intake of unhealthy food taken on very regular basis may bring even further negative impact on health if associated with excessive time using of screen-based electronic devices. OBJECTIVE: To estimate the association between the use of different types of screen-based devices and the intake of unhealthy foods amongst children and adolescents and to determine whether daily physical activity (DPA) has a moderating effect on the association. METHODS: Cross-sectional study carried out with a probabilistic sample of students from second to fifth grade of public elementary schools in Feira de Santana, Bahia (n = 2,477; girls: 53.2%; age: 9.1 ± 1.38 years; BMI z-score 0.37 ± 4.19 Kg/m²). Food intake, screen use, and physical activity were assessed using an online questionnaire based on previous day recall (Web-CAAFE). Prevalence Ratios (PR) and 95% Confidence Intervals (95%CI) were estimated via multiple zero-inflated negative binomial regression, with adjustments for sex, age, and weekly frequency of school meal intake. The moderating effect of DPA was verified by inserting interaction terms with each screen-based device individually and with the daily sum of screen-based device exposure (∑ Screens). RESULTS: The majority of students (72.2%) reported using screens. The intake of unhealthy foods was positively associated with the use of cell phones (PR = 1.21; 95%CI = 1.13-1.30), computers (PR = 1.33; 95%CI = 1.22-1.46), and video games (PR = 1.36; 95%CI = 1.22-1.52). TV use was inversely associated with intake of unhealthy foods (PR = 0.92; 95%CI = 0.87-0.99). DPA moderated the effect of video game use on intake of unhealthy foods, that is, among students with DPA ≥ 4 who used video games, the intake of unhealthy foods was 21% lower (PR = 0.79; 95%CI = 0. 65-0.97). Overall, ∑ Screen-based devices were associated with a 20% increase in intake of unhealthy foods. CONCLUSION: The intake of unhealthy foods was positively associated with the use of cell phones, computers, and video games. In addition, a frequency of four or more DPA attenuated the effect of video game exposure on intake of unhealthy foods. Upcoming investigations on the use of screen-based devices and the intake of unhealthy foods among schoolchildren should consider the exposure to different types of screen-based devices, as well as the influence of DPA.

Associação entre parto cesáreo e pressão arterial elevada em pré-escolares: um estudo transversal / Association between cesarean section and high blood pressure among early elementary schoolchildren: a cross-sectional study / Asociación entre los partos por cesárea y la presión arterial alta en preescolares: un estudio transversal

O parto cesáreo é apontado como fator de risco para diversas doenças crônicas. Neste estudo, objetivou-se averiguar a associação entre parto cesáreo e pressão arterial (PA) de crianças de 6 anos. Trata-se de estudo transversal conduzido em Feira de Santana (BA), com 635 pares de mãe e filho. O tipo de parto foi categorizado em cesárea e vaginal. A PA foi aferida por meio de esfigmomanometria e considerada elevada quando atingiu níveis iguais ou maiores ao percentil 90 para idade, sexo e altura. Razões de prevalência brutas (RPbruta) e ajustadas (RPajustada) e respectivos intervalos de confiança de 95% (IC95%) foram estimados via regressão logística múltipla. A cesariana ocorreu em 46,5% dos casos, as prevalências de pressão arterial sistólica (PAS) e diastólica (PAD) elevadas foram de 17,2% e 5,6%, respectivamente. O excesso de peso foi verificado em 28,6% das crianças. A maior prevalência de PAS elevada foi observada entre as crianças que nasceram por cesariana (61%) em relação às que nasceram por parto vaginal (RPbruta: 1,51; IC95%: 1,07-2,14; RPajustada: 1,61; IC95%: 1,05-2,46). A idade materna ao nascimento da criança foi fator de interação na associação principal, assim, as crianças nascidas via parto vaginal exibiram maior prevalência de PAS elevada, comparadas às nascidas via cesárea. O parto cesáreo se associou à PAS elevada aos 6 anos de idade.

Cesarean delivery is considered a risk factor for several chronic diseases. This study aimed to investigate the association between cesarean section and blood pressure (BP) in 6-year-old children. This is a cross-sectional study carried out in Feira de Santana, (BA) with 635 mother-child pairs. The type of birth was categorized into cesarean and vaginal. The BP was measured by using sphygmomanometry and considered high when it reached levels equal or higher than the 90th percentile for age, gender, and height. Crude (PRcrude) and adjusted (PRadjusted) prevalence rate and respective 95% confidence intervals (95%CI) were estimated by multiple logistic regression. Cesarean section occurred in 46.5% of the cases, the prevalence of high systolic (SBP) and diastolic (DBP) blood pressure were 17.2% and 5.6%, respectively. Excess weight was verified in 28.6% of the children. The highest prevalence of high SBP was among children who were born by cesarean section (61%) compared with those who were born vaginally (PRcrude: 1.51; 95%CI: 1.07-2.14; PRadjusted: 1.61; 95%CI %: 1.05-2.46). Maternal age at the birth of the child was an interaction factor in the main association, thus, children born vaginally had a higher prevalence of elevated SBP, compared with those born via cesarean section. Cesarean section was associated with increased SBP at six years of age.

El parto por cesárea presenta un factor de riesgo para varias enfermedades crónicas. El objetivo de este estudio fue investigar la asociación entre el parto por cesárea y la presión arterial (PA) en niños de 6 años de edad. Se trata de un estudio transversal, realizado en Feira de Santana, en Bahía (Brasil), con 635 pares de madre e hijo. El tipo de parto se clasificó en cesárea y vaginal. La PA se midió mediante esfigmomanometría y se consideró alta cuando alcanzó niveles más altos o iguales al percentil 90 para edad, sexo y talla. Las razones de prevalencia crudas (RPcrudas) y ajustadas (RPajustadas) y los respectivos intervalos de confianza del 95% (IC del 95%) se estimaron mediante regresión logística múltiple. La cesárea ocurrió en el 46,5%, las prevalencias de presión arterial sistólica (PAS) y diastólica (PAD) altas fueron el 17,2% y el 5,6%, respectivamente. El exceso de peso se presentó en el 28,6% de los niños. La mayor prevalencia de PAS alta se observó entre los niños nacidos por cesárea (61%) en comparación con los nacidos por vía vaginal (RPcruda: 1,51; IC95%: 1,07-2,14; RPajustada: 1,61; IC95%: 1,05-2,46). La edad materna al nacimiento del niño fue un factor de interacción en la principal asociación, así, los niños nacidos por vía vaginal tuvieron una mayor prevalencia de PAS elevada en comparación con los nacidos por cesárea. El parto por cesárea se asoció con un aumento de la PAS a los 6 años de edad.

Ambiente do bairro e da escola e sua associação com atividade física diária e uso de telas / Neighborhood and school environment and its association with daily physical activity and screen use

O objetivo deste estudo transversal foi analisar a associação entre ambiente construído no bairro e na escola e atividade física diária (AFD) e uso de telas diário (TD) entre estudantes de diferentes padrões de comportamentos. Participaram estudantes (9,1 ± 1,38 anos, 53,2% meninas) do 2º ao 5º ano de escolas públicas (n = 2.384) da cidade de Feira de Santana, BA. Atividades físicas e comporta-mentos sedentários foram avaliadas através de questionário online (Web-CAAFE) e utilizadas para definir os padrões de comportamentos por análise de cluster, segmentada por sexo. Ambiente cons-truído na escola (parquinho e espaços cobertos para atividades físicas) e no bairro (quadras esportivas, campos de futebol, parques e praças) foram as exposições. Os desfechos, AFD e TD, foram obtidos pelos somatórios dos relatos de um dia. Modelos de regressão binomial negativa, controlados por idade e escore-z de Índice de Massa Corporal, estimaram razões de prevalência (RP) e intervalos de confiança de 95% (IC95%). A AFD associou-se a praças entre meninas "jogadoras ativas" (RP = 1,35; IC95%: 1,09 - 1,68) e a Espaços cobertos para atividades físicas entre "sedentárias/executoras de tarefas domésticas" (RP = 0,86; IC95%: 075 - 0,97). Entre meninos "sedentários em atividades acadêmicas" a AFD associou-se a Campos de futebol (RP = 1,20; IC95%: 1,02 - 1,42) e TD a Parquinho (RP = 1,17; IC95%: 1,00 - 1,37). TD também foi associado a Espaços cobertos para atividade física entre "sedentários em telas" (RP = 1,28; IC95%: 1,04 - 1,57). AFD e TD de meninos e meninas com diferentes padrões de comportamento foram associados a diversos fatores do ambiente construído

The aim of this cross-sectional study was to analyze the association between the built environment at school and in the neighborhood and daily physical activity (DPA) and daily screen use (DS) among students with different behavioral patterns. Participants were students (9.1 ± 1.38 years, 53.2% girls) from the 2nd to the 5th year of public schools (n = 2,384), in the city of Feira de Santana, BA. Physical activities and sed-entary behaviors were assessed using an online questionnaire ( Web-CAAFE) and used to define behavioral patterns by cluster analysis, segmented by gender. Built environment at school (playground and covered spaces for physical activities) and in the neighborhood (sports courts, soccer fields, parks and squares) were the exposures variables. The outcomes, DPA and DS, were obtained by the sum the one-day reports. Mul-tiple negative binomial regression models, controlled for age and Body Mass Index z-score, were estimated prevalence ratios (PR) and 95% confidence intervals (95%CI). DPA was associated with squares among "active players" girls (PR = 1.35; 95%CI: 1.09 - 1.68) and with covered spaces for physical activities among "sedentary/Household chores performers" (PR = 0.86; 95%CI: 075 - 0.97). Among "sedentary in academic tasks" boys, DPA was associated with Soccer fields (PR = 1.20; 95%CI: 1.02 - 1.42) and DS with Play-ground (PR = 1.17; 95%CI: 1.00 - 1.37). DS was also associated with Covered spaces for physical activity among "sedentary on screen" (PR = 1.28; 95%CI: 1.04 - 1.57). DPA and DS of boys and girls with different behavior patterns were associated with several built environment factors

Food consumption pattern and excess weight in preschoolers: a cross-sectional study / Padrão de consumo alimentar e excesso de peso em pré-escolares: estudo transversal / Patrón de consumo de alimentos y sobrepeso en niños en edad preescolar: estudio transversal

Background and objectives: children's food-related lifestyle brought changes in their weight status and eating patterns. We aimed to investigate the association between food consumption pattern and excess weight in preschoolers aged six. Methods: a cross-sectional analysis of a prospective birth cohort, in 2004, in Feira de Santana-BA. Food consumption frequency was verified, characterized by patterns and established through a food frequency questionnaire, validated in a previous study, in pattern 1: milk, vegetables, cereals, legumes, fruits and fish; pattern 2: snacks, soda/artificial juice, oils, sweets and coffee/tea; pattern 3: sausages, fast food, ketchup/mayonnaise and egg; pattern 4: red meat and chicken. Excess weight was defined according to the World Health Organization criteria. The main association was assessed using Pearson's chi-square test and Poisson regression. Results: a total of 618 children were investigated. Excess weight occurred in 28.6%, and pattern 3 frequency was 68%. In the bivariate analysis, only pattern 3 was associated with children's excess weight (PR: 1.23; 95%CI: 1.01-1.63). In the multivariate analysis, the prevalence of excess weight children who consumed pattern 3 was 50% (adjustedPR: 1.50; 95%CI: 1.01­1.93). Conclusion: moderate/high consumption of sausages, fast food, ketchup/mayonnaise and eggs was associated with excess weight among children in the sample.(AU)

Periodontitis is a factor associated with dyslipidemia.

OBJECTIVE: To investigate the association between the severity of periodontitis (exposure) and dyslipidemia (outcome). METHODS: This was a cross-sectional study of users of public health services. Periodontitis was defined using the Center for Disease Prevention and Control and the American Academy of Periodontology criteria. Lipid evaluation used data on systemic biomarkers. Dyslipidemia diagnosis was based on the Guidelines of total cardiovascular risk of the World Health Organization. Weight, height, waist circumference, and blood pressure were measured, and socioeconomic-demographic, lifestyle behavior factors, general and oral health conditions of the participants were collected. Hierarchical and logistic regression analyzes were used to determine the association between the exposures and the outcome. Odds Ratios, unadjusted and adjusted, and 95% confidence intervals were estimated. RESULTS: Of 1,011 individuals examined, 75.17% had dyslipidemia, and 84.17% had periodontitis, 0.2% with mild, 48.56% moderate, and 35.41% severe disease. The association between periodontitis and dyslipidemia was maintained through hierarchical analysis and in the multiple regression modeling, showing that the occurrences of dyslipidemia in the group with periodontitis, and its moderate and severe levels, were, respectively, 14%, 30%, and 16% higher compared with those without periodontitis. CONCLUSIONS: The results showed a positive association between moderate and severe periodontitis and dyslipidemia.

Oropharyngeal colostrum immunotherapy and nutrition in preterm newborns: meta-analysis.

OBJECTIVE: To investigated the effect of oropharyngeal colostrum immunotherapy in reducing the time required for very low birth weight preterm newborns (VLBW-PTNB: < 1,500g and < 37 weeks) to achieve full enteral nutrition. METHODS: Literature search was conducted using four databases, including gray literature, with additional manual search of the references of selected articles. Eligibility criteria consisted of randomized clinical trials, without restriction regarding the date or language of the publication. Two independent reviewers performed the article selection and data extraction. The random-effects meta-analysis used a non-standard technique to assess the mean difference in days to achieve full enteral nutrition, carried out by the Stata 15 statistic program. RESULTS: The systematic review comprised 10 studies, and five were selected for meta-analysis, with a population of 764 VLBW-PTNB and gestational age of birth between 25 and 32 weeks. The studies were conducted between 2011 and 2018 in North America, Asia and Africa, with only one conducted in South America. Altogether, they reported the number of days it took 708 VLBW-PTNB to achieve full enteral nutrition, with newborns treated with immunotherapy showing a shorter time in only three studies. Meta-analysis showed a mean difference of -4.26 days, (95% CI -7.44; -1.08d), with high heterogeneity (I2 = 83.1%). CONCLUSION: The use of oropharyngeal colostrum immunotherapy can reduce the time for VLBW-PTNB to achieve full nutrition when compared to those who used a placebo or received routine care.

Risk factors for and protective factors against breastfeeding interruption before 2 years: a birth cohort study.

BACKGROUND: Little is known about the factors associated with the World Health Organization (WHO) recommendation of breastfeeding for at least 2 years. The objective of this study was to identify risk factors for and protective factors against breastfeeding interruption before 2 years of age. METHODS: In this live birth cohort, mother and infant dyads were followed for 2 years. Data collection was performed at the maternity ward and subsequently at the children's homes, monthly during the first 6 months of life and then at 9, 12, 18, and 24 months. The outcome of interest was breastfeeding interruption before 2 years of age. Median duration of breastfeeding was estimated using Kaplan-Meier's survival analysis, and the associations were tested using Cox's hierarchical multivariate model. Significance was set at 5%. RESULTS: Data from a total of 1344 dyads were assessed. Median breastfeeding duration was 385 days. The following risk factors for breastfeeding interruption were identified: white skin color (adjusted hazard ratio [HRa]: 1.31; 95% confidence interval [95%CI]: 1.10-1.56), primiparity (HRa: 1.21; 95%CI: 1.05-1.40), working outside the home (HRa: 1.52; 95%CI: 1.30-1.77), child sex male (HRa: 1.18; 95%CI: 1.03-1.35) and use of a pacifier (HRa: 3.46; 95%CI: 2.98-4.01). Conversely, the following protective factors were identified: lower family income (HRa: 0.81; 95%CI: 0.71-0.94), mother-infant bed-sharing (HRa:0.61, 95%CI: 0.52-0.73), on-demand breastfeeding in the first month (HRa: 0.64; 95%CI: 0.47-0.89) and exclusive breastfeeding at 4 months (HRa: 0.58, 95%CI: 0.48-0.70). CONCLUSIONS: The findings allowed to identify both risk factors for and protective factors against breastfeeding interruption before 2 years of age. Knowledge of these factors may help prevent this event and aid in the development of programs that help women maintain breastfeeding for at least 2 years, as recommended by the WHO.

Eating habits of breastfed and non-breastfed children up to one year of age / Hábitos alimentares de crianças menores de um ano de idade amamentadas e não amamentadas / Hábitos alimentarios de niños de un año de edad lactantes y no lactantes

Eating practices in the breastfeeding period constitute an important boundary to the formation of eating habits throughout life. This study aims to evaluate the association between breastfeeding and eating habits of children younger than one year of age in a big city in Northeastern Brazil by a cross-sectional study in which 1471 mothers/children were interviewed in 71 vaccination sites. We surveyed eating habits of children in the 24 hours preceding the data collection: breastfeeding, consumption of other milk sources, water, tea, juice, fruit, family usual meal, sweetened food, cookies, snacks, soft drinks and coffee; as well as bottle and pacifier use. Breastfed children less than three months old, compared with the non-breastfed ones, presented higher consumption of water (12.8% vs. 69.6%), tea (14.6% vs. 45.5%) and fruit juice (5% vs. 30.4%). At the age of three to six months, breastfed children showed lower prevalence of other milk sources (32.4% vs. 92.2%) and sweetened foods (19.0% vs. 60.0%). Breastfeeding figured as a protective factor against early consumption of unhealthy foods such as cookies/salty snacks (3­6 months old) and sweetened foods in all quarters. Bottles and pacifiers use was significantly higher in non-breastfed children, especially in the second quarter, with a prevalence of 93.8% and 100%, respectively. Breastfed children showed better eating habits when compared with the non-breastfed ones.

As práticas alimentares no período da amamentação constituem um importante limite para a formação dos hábitos alimentares ao longo da vida. Este trabalho avalia a associação entre amamentação e o hábito alimentar de crianças menores de um ano em uma cidade de grande porte do Nordeste brasileiro, por meio de um estudo transversal realizado com 1.471 mães/responsáveis em 71 unidades de vacinação. Foram pesquisadas as práticas alimentares das crianças nas 24 horas que precederam a coleta de dados: aleitamento, consumo de outro leite, água, chá, suco, frutas, refeição da família, alimentos adoçados, ingesta de biscoitos, salgadinhos, refrigerantes e café, além do uso de mamadeiras e chupetas. Foi constatado que nas crianças amamentadas menores de três meses, quando comparadas com as não amamentadas, houve maior consumo de água (12,8% contra 69,6%), chá (14,6% contra 45,5%) e suco de fruta (5% contra 30,4%). Na faixa etária de três a seis meses, as crianças amamentadas apresentaram menor prevalência do consumo de outro leite (32,4% contra 92,2%) e alimentos adoçados (19,0% contra 60,0%). O aleitamento materno figurou como fator protetor contra o consumo precoce de alimentos não saudáveis como biscoito/salgadinhos (3-6 meses) e alimentos adoçados em todos os trimestres. O uso de chupetas e mamadeiras foi expressivamente mais alto nas crianças não amamentadas, especialmente no segundo trimestre, com prevalência de 93,8% e 100%, respectivamente. As crianças amamentadas apresentaram melhores hábitos alimentares quando comparadas às não amamentadas.

Las prácticas alimentarias en el periodo de lactancia son importantes para la formación de los hábitos alimentarios a lo largo de la vida. Este trabajo analiza la asociación entre la lactancia materna y los hábitos alimentarios de niños menores de un año en una gran ciudad del Nordeste de Brasil, a partir de un estudio transversal en el que se entrevistó a 1.471 madres/responsables en 71 unidades de vacunación. Se encuestaron los hábitos alimentarios de los niños en las 24 horas anteriores a la recogida de datos, la lactancia materna, el consumo de otras fuentes de leche, agua, té, zumo, fruta, comida habitual de la familia, alimentos azucarados, galletas, aperitivos, refrescos e ingesta de café; y el uso de biberones y chupetes. Entre los niños lactantes de menos de tres meses en comparación con los no lactantes, hubo un mayor consumo de agua (12,8% frente al 69,6%), té (14,6% frente al 45,5%) y zumo de frutas (5% frente al 30,4%). A la edad de tres a seis meses, los niños lactantes tenían una alimentación con menor prevalencia de otras fuentes de leche (32,4% frente al 92,2%) y de alimentos azucarados (19,0% frente al 60,0%). La lactancia materna figuró como factor de protección contra el consumo temprano de alimentos poco saludables como galletas/aperitivos (3 a 6 meses) y alimentos azucarados en todos los trimestres. El uso de chupetes y biberones fue significativamente mayor en los niños no lactantes, especialmente en el segundo trimestre, con una prevalencia del 93,8% y del 100%, respectivamente. Los niños lactantes tenían mejores hábitos alimentarios en comparación con los no lactantes.

Breastfeeding technique and the incidence of nipple traumas in puerperal women attended in a city hospital: intervention study / Técnica de amamentar e a incidência de traumas mamilares em puérperas atendidas em um hospital municipal: estudo de intervenção

Abstract Objectives: to evaluate the effect of an intervention on the incidence of nipple trauma and the quality of breastfeeding technique in the first month of postpartum. Methods: this is a quasi-randomized intervention study with 180 puerperal women equally distributed between experimental and control groups. The intervention was performed at a maternity and consisted of an educational session on breastfeeding technique. A descrip-tive analysis of the groups' characteristics was performed, comparing the frequencies of unfa-vorable parameters related to breastfeeding technique between groups. Pearson's chi-square test and Fisher's test were used, and p≤0.05 was adopted as the critical level of significance. Results: at 30 days, 64% and 15% of the mothers used the technique correctly, respec-tively, in the experimental and control groups with RR=4.87 (CI95%=2.93-8.34); NNT=1.96 (CI95% =1.61-2.72); p<0.001. In the experimental group, a decrease was observed in the unfavorable parameters of the breastfeeding technique (p≤0.05). The incidence of nipple trauma was 30% in the experimental group and 38.9% in the control group (p=0.21). Conclusions: the intervention was insufficient to prevent nipple trauma in the experi-mental group, but significantly improved the quality in the breastfeeding technique.

Resumo Objetivos: avaliar o efeito de uma intervenção na incidência de traumas mamilares e na qualidade da técnica de amamentar no primeiro mês pós-parto. Métodos: trata-se de um estudo de intervenção quasi randomizado com 180 puérperas distribuídas entre os grupos experimental e controle. A intervenção foi realizada na mater-nidade e consistiu de sessão educativa sobre a técnica de amamentar. Foi realizada análise descritiva das características dos grupos, comparadas as frequências dos parâmetros desfa-voráveis da técnica de amamentar. O teste do qui-quadrado de Pearson e teste de Fisher foram utilizados, sendo adotado p≤ 0,05 como nível crítico de significância. Resultados: aos 30 dias, 64% e 15%, das mães apresentaram técnica correta, respectiva-mente, nos grupos experimental e controle com RR= 4,87 (IC95%=2,93-8,34); NNT= 1,96 (IC95%=1,61-2,72); p<0,001.No grupo experimental percebeu-se que houve diminuição dos parâmetros desfavoráveis da técnica de amamentar (p≤0,05). A incidência de trauma mamilar foi de 30% no grupo experimental e 38,9% no grupo controle (p=0,21). Conclusão: no grupo experimental a intervenção realizada não foi suficiente para prevenir a ocorrência de traumas mamilares, porém melhorou significantemente a qualidade da técnica de amamentar.

Uso de chupeta e a interrupção do aleitamento materno exclusivo: estudo de coorte / Pacifier use and interruption of exclusive breastfeeding: a cohort study / Uso de chupete e interrupción de lactancia materna exclusiva: estudio de cohorte

Este estudo se propôs a averiguar a existência de associação entre o uso de chupeta e a interrupção precoce do aleitamento materno exclusivo (AME) ao longo dos quatro primeiros meses de vida da criança. Para isso, utilizaram-se dados de uma coorte composta por 1.037 mães e crianças. Para estimar a associação entre a variável desfecho e aquelas de exposição ao longo do tempo, foi utilizada a técnica de Equação de Estimação Generalizada (GEE). Foi averiguado que a interrupção precoce do AME e o uso de chupeta aumentaram gradativamente conforme a idade da criança; no quarto mês, mais da metade das crianças já estava desmamada e fazia uso de chupeta. Os resultados da estimativa obtida por meio da GEE mostraram que permaneceu significativo apenas o uso de chupeta associado à baixa escolaridade materna como risco de interrupção precoce do AME, quando ajustado para as demais covariáveis. Os resultados reforçam a interferência negativa do uso da chupeta na duração do AME e a necessidade de informar às mães sobre as desvantagens do uso de chupetas.

This study investigates the possible association between pacifier use and early termination of exclusive breastfeeding for four months following birth. Data was collected from a cohort comprising1037 mothers and children. The association between the outcome variable and the exposure variables over time was estimated using the Generalized Estimation Equation (GEE). Early weaning and pacifier use increased gradually with the child's age; by the fourth month, more than half of the children were already weaned and using a pacifier. GEE estimations showed that only pacifier use associated with low maternal schooling level remained significant as a risk of early weaning, when adjusted for the other covariates. The results reinforce the negative interference of pacifier use on EB duration and the need to inform mothers about the disadvantages of pacifier use.

Este estudio tuvo como objetivo investigar la existencia de una asociación entre el uso de chupete y la interrupción temprana de la lactancia materna exclusiva (LME) durante los primeros cuatro meses de vida del niño. Se utilizaron datos de una cohorte, compuesta por 1.037 madres y niños. Para estimar la asociación entre la variable resultado y las de exposición en el tiempo, se utilizó la técnica de Ecuación de Estimación Generalizada (GEI). La interrupción temprana de la LME y el uso de un chupete aumentaron gradualmente conforme a la edad del niño; en el cuarto mes, más de la mitad de los niños ya habían sido destetados y usaban chupete. Los resultados de la estimación obtenida a través de GEI mostraron que solo el uso de chupetes asociado a bajos niveles de educación materna permaneció significativo como riesgo de interrupción temprana de la LME, cuando se ajustó con las otras covariables. Los resultados apuntan la interferencia negativa del uso de chupete en la duración de la LME y la necesidad de informar a las madres sobre las desventajas del uso de chupete.

Effect of an educational intervention on the breastfeeding technique on the prevalence of exclusive breastfeeding / Efeito de uma intervenção educativa sobre a técnica de amamentação na prevalência do aleitamento materno exclusivo

Abstract Objectives: to evaluate the effect of an intervention directed to the breastfeeding technique in the prevalence of exclusive breastfeeding in the first month of life. Methods: this is a quasi-randomized intervention study conducted in a public maternity ward accredited in the Baby-Friendly Hospital Initiative. The intervention consisted of individual orientations on the breastfeeding technique in the first 48 hours after delivery, with the help of a breast model, doll, and movie. The control group was oriented by researchers about the importance of breastfeeding, and received hospital orientations. Data were collected in the maternity ward, and at the end of the first month in the hospital's outpatient service by implementing a questionnaire, observing the baby's breastfeeding technique and examining breasts. Results: the prevalence of exclusive breastfeeding in the first month of life of the infant was 76.6% in the experimental group, and 52.2% in the control group. RR=1.46 (CI95%=1.16-1.84); NNT=4.09; p=0.001. The trained women presented a correct breast-feeding technique in 64.04%, much higher when compared to those who did not receive training (15.11%;RR=4.87[CI95%=2.93-8.34]; NNT=1.96;p<0.001). Conclusions: the use of audiovisual resources, use of instruments (model breast and doll), and type of individualized approach contributed to an increased prevalence of exclusive breastfeeding up to 30 days after delivery.

Resumo Objetivos: avaliar o efeito de uma intervenção direcionada à técnica de amamentação na prevalência de aleitamento materno exclusivo no primeiro mês de vida. Métodos: foi realizado um estudo de intervenção quasi randomizado em uma maternidade pública, credenciada como Amigo da Criança. A intervenção consistiu em orientações individuais sobre a técnica de amamentação nas primeiras 48 horas após o parto, com ajuda de seio cobaia, boneca e filme. O grupo controle foi orientado sobre a importância do aleitamento materno pelas pesquisadoras, além das orientações fornecidas pelo hospital. A coleta de dados ocorreu na maternidade e ao final do primeiro mês em serviço ambulatorial do hospital, mediante a aplicação de um questionário, observação da mamada e exame das mamas. Resultados: a prevalência do aleitamento materno exclusivo, no primeiro mês de vida do lactente, foi de 76,6% no grupo experimental e 52,2% no grupo controle. RR=1,46 (IC95%=1,16-1,84); NNT=4,09; p=0,001. As mulheres que sofreram a intervenção, apresentaram técnica correta de amamentação em proporção significativamente maior que os controles: 64,04% vs 15,11%, RR= 4,87 [IC95%= 2,93-8,34] NNT= 1,96; p<0,001. Conclusões: a utilização de recursos audiovisuais, uso de instrumentos (seio cobaia e boneca) e tipo de abordagem individualizada contribuíram para o aumento da prevalência do aleitamento materno exclusivo até 30 dias pós parto.

Exclusive breast-feeding is associated with reduced pacifier sucking in children: Breast-feeding and pacifier-sucking habit.

BACKGROUND: Studies suggest that when children do not achieve the emotional satiety and adequate stimulus provided by breast-feeding, they exhibit sucking behaviors. This study aimed to estimate the association from 4 through 6 months of exclusive breast-feeding (EB) postpartum and pacifier-sucking behavior at 12 months of life. METHODS: A cohort study was conducted with 1,037 infants, born alive and monitored up to 12 months. At 4 and 6 months after birth, the children were classified according to the type of breast-feeding they had received: exclusive, predominant, complementary, or none. The prevalence of pacifier-sucking behavior was calculated, and the association between the 2 events was estimated. Mothers' socioeconomic-demographic characteristics, delivery features, and prenatal care, as well as the biological characteristics of the children, were determined. Relative risk (RR) and 95% confidence intervals (95% CI) were calculated. RESULTS: In comparison with EB infants, the RR of pacifier-sucking behavior at 12 months of life was higher in children receiving complementary breast-feeding or no breast-feeding for both 4 months (RRadjusted, 1.68 [95% CI, 1.39 to 2.02] and RRadjusted, 2.67 [95% CI, 2.24 to 3.17], respectively) and 6 months (RRadjusted, 1.43 [95% CI, 1.03 to 2.00] and RRadjusted, 3.30 [95% CI, 2.40 to 4.54], respectively). CONCLUSIONS AND PRACTICAL IMPLICATIONS: EB for 6 months postpartum is associated with reduced pacifier-sucking behavior, adjusted for maternal color, number of prenatal consultations, and family income. Promotion of EB may reduce the use of pacifiers and their potential deleterious effects on oral health. Dental health care professionals should consider discussing the importance of breast-feeding with their patients with regard to the possible development of sucking habits in their children.

Food consumption pattern and obesity in preschool children in Feira de Santana, Bahia, Brazil / Padrão de consumo alimentar e obesidade em pré-escolares, Feira de Santana, Bahia

ABSTRACT Objective To evaluate the association between food consumption patterns and obesity in preschool children in Feira de Santana, Bahia, Brazil. Methods Cross-sectional, population-based nested within a live-birth cohort study of 813 children, which has started in 2004 in Feira de Santana, Bahia. The anthropometric status among children under four years of age was evaluated based on their body mass index; obesity/severe obesity was defined as a Z-score >+2. The Food Frequency Questionnaire was used to identify dietary patterns using principal components analysis. The association between obesity and food consumption patterns was assessed using Pearson's Chi-squared test and logistic regression, adopting p<0.05 to denote statistical significance. Results Obesity was detected in 12.7% of the children investigated. Four food consumption patterns were identified: dietary pattern 1 (milk and other dairy products, vegetables and tubers, cereals, legumes, fruits, and fish); dietary pattern 2 (deep-fried or baked snacks, soft drinks/artificial fruit juices, oils and fats, sweets, and coffee/tea); dietary pattern 3 (encased meats, fast food, ketchup/mayonnaise, and eggs); and, dietary pattern 4 (chicken and red meats). Obesity was statistically associated with high adherence to the dietary pattern 3 (OR=1.92; 95%CI=1.01-3.66). Conclusion The results obtained showed that the high intake of energy-dense foods (dietary pattern 3) was a contributing factor to childhood obesity. These data reinforce the need for public policies and food education programs in health units and schools, aiming to change children's eating habits, significant predictors of nutritional problems.

RESUMO Objetivo Avaliar a associação entre padrões de consumo alimentar e a obesidade de pré-escolares em Feira de Santana, Bahia. Métodos Análise transversal de 813 crianças de uma coorte de nascidos vivos de base populacional, iniciada em 2004 em Feira de Santana, Bahia. O estado antropométrico entre menores de quatro anos foi avaliado por meio do cálculo do índice de massa corporal, sendo a obesidade/obesidade grave definida em escore Z (>+2). O Questionário de Frequência Alimentar foi o instrumento utilizado para identificar os padrões alimentares por meio da análise fatorial de componentes principais. A associação entre a obesidade e os padrões de consumo alimentar foi avaliada mediante teste Qui-quadrado de Pearson e da regressão logística, tomando-se como critério de associação, valor de p<0,05. Resultados A obesidade para idade foi observada em 12,7% das crianças estudadas. Foram identificados quatro padrões alimentares: padrão alimentar 1 (leite e derivados, verduras e tubérculos, cereais, leguminosas, frutas e pescados); padrão alimentar 2 (salgadinhos, refrigerante/sucos artificiais, óleos e gorduras, doces e café/chá); padrão alimentar 3 (embutidos, fast-food, catchup/maionese e ovos); e, padrão alimentar 4 (frango e carnes vermelhas). A obesidade mostrou-se estatisticamente associada à alta adesão ao padrão alimentar 3 (OR=1,92; IC95%=1,01-3,66). Conclusão Os resultados da pesquisa mostraram que a elevada ingestão de alimentos altamente energéticos (padrão alimentar 3) foi fator contributivo para a ocorrência da obesidade na infância. Estes dados reforçam a necessidade de políticas públicas e programas de educação alimentar, nas unidades de saúde e escolas, para mudança dos hábitos alimentares das crianças, importante preditor de problemas nutricionais.

Factors associated with the use of the Child Health Handbook in a large city of the Brazilian Northeast, 2009. / Fatores associados ao uso da Caderneta de Saúde da Criança em uma cidade de grande porte do nordeste brasileiro, 2009.

This study aimed to investigate the factors associated with mothers reading the Child Health Handbook (CHH) and health professionals completing this instrument, in Feira de Santana, Bahia, 2009. This is a cross-sectional study with the application of 727 forms to mothers of children under one year of age. The outcomes studied were mother reading the CHH and health professionals completing weight and height measures. We performed a logistic regression analysis with p ≤ 0.05. The prevalence of reading, weight and height were, respectively, 81.1%, 68.9% and 47.3%. Mothers with a higher level of education had a greater chance of reading the CHH. Recording weight and height was more prevalent in mothers who were under 35 years of age. Performing childcare in areas of the Family Health Program or the Community Health Workers was positively associated with the height's record, despite the low prevalence of records. Child age greater than six months was positively associated with all outcomes. It demonstrated the underutilization of CHH by mothers and health professionals, which indicates the need for training of health professionals and guidance to mothers on the importance and management of this issue.

Fatores associados ao uso da Caderneta de Saúde da Criança em uma cidade de grande porte do nordeste brasileiro, 2009 / Factors associated with the use of the Child Health Handbook in a large city of the Brazilian Northeast, 2009

Resumo O objetivo do estudo foi averiguar os fatores associados à leitura da Caderneta de Saúde da Criança (CSC) pelas mães e a seu preenchimento pelos profissionais de saúde, em Feira de Santana (Bahia), em 2009. Estudo transversal com aplicação de 727 formulários às mães de crianças menores de um ano. Os desfechos estudados foram: leitura materna da caderneta e preenchimento de medidas de peso e comprimento, por profissionais de saúde. Realizou-se análise de regressão logística com valor de p ≤ 5%. A prevalência de leitura, medidas de peso e comprimento foram, respectivamente, 8,1%, 68,9% e 47,3%. Maior escolaridade materna associou-se a maiores chances de leitura. Registros de peso e comprimento foram mais prevalentes em mães com idade < 35 anos. Realizar puericultura em áreas do Programa de Saúde da Família ou dos Agentes Comunitários de Saúde associou-se positivamente com anotações do comprimento, apesar das baixas prevalências dos registros. Idade da criança ≥ 6 meses associou-se a todos os desfechos. Demonstrou-se a subutilização da CSC por mães e profissionais de saúde, indicativos da necessidade de medidas educativas com treinamentos dos profissionais de saúde e orientações às mães sobre a importância e o manejo da mesma.

Factors associated to nipple trauma in lactation period: a systematic review / Fatores associados ao trauma mamilar no período lactacional: uma revisão sistemática

Abstract Objectives: To identify the characteristics associated to nipple trauma in nursing mothers and propose a theoretical model explaining in hierarchical levels its determining factors. Methods: a systematic review of the literature based on the search of epidemiological studies of factors associated to nipple trauma in the databases of Medical Literature Analysis and Retrieval System Online/Pubmed, Literatura Latino-Americana and Caribe em Ciências da Saúde (Latin American Literature and Caribbean Health Sciences) and ScienceDirect. The conduct on searching articles occurred until June 2016. Results: 17 articles were selected which investigated 27 variables and found a significant association between 16 of these variables and nipple trauma. The factors associated to nipple trauma reported in two or more studies were: mother of race/color white or yellow, primiparity, inadequate position between mother and child during breastfeeding and handling the infant incorrectly to the mother's breast. Guidance received on handling and positioning the infant during prenatal care was a protective factor against nipple trauma. Conclusions: in the theoretical model explaining the factors associated to nipple trauma in hierarchical levels, the variables classified at the proximal level were the most investigated and were identified as risk factors in selected studies, indicating that in the postpartum care period is an important protective factor against nipple trauma.

Resumo Objetivos: identificar as características associadas ao trauma mamilar em nutrizes e propor um modelo teórico explicativo, em níveis hierarquizados, dos seus fatores determinantes. Métodos: revisão sistemática da literatura fundamentada na busca de estudos epidemiológicos sobre os fatores associados ao trauma mamilar nas bases de dados Medical Literature Analysis and Retrieval System Online/Pubmed, Literatura Latino-Americana e do Caribe em Ciências da Saúde e ScienceDirect. A condução da busca dos artigos ocorreu até junho de 2016. Resultados: selecionou-se 17 artigos, que investigaram 27 variáveis e encontraram associação significante entre 16 dessas variáveis e o trauma mamilar. Os fatores associados ao trauma mamilar relatados em dois ou mais estudos foram: mãe de raça/cor branca ou amarela, primiparidade, posicionamento inadequado entre mãe e filho durante a mamada e pega incorreta do lactente ao seio materno. A orientação quanto à pega e posicionamento do lactente recebida durante o pré-natal foi fator de proteção contra o trauma mamilar. Conclusões: no modelo teórico explicativo dos fatores associados ao trauma mamilar em níveis hierarquizados, as variáveis classificadas no nível proximal foram as mais investigadas e identificadas como fatores de risco nos estudos selecionados, sinalizando que a atenção ao pós-parto é um importante fator de proteção contra os traumas mamilares.

[Maternal intention to breastfeed: a systematic review]. / Intenção materna de amamentar: revisão sistemática.

This study seeks to identify the factors associated with maternal intention to breastfeed (MIB) in pregnant women. A systematic review of articles in the Medical Literature Analysis and Retrieval System Online (PubMed/Medline) and the Latin American and Caribbean Literature in Health Sciences (Lilacs) databases was conducted. Two independent reviewers performed the search, using the "Medical Subject Headings" and "Key words in Science and Health" vocabulary, referring to: breastfeeding, intention, and pregnant women. Research articles in English, Portuguese and Spanish that analyzed MIB as an outcome were selected. The studies were classified by methodological quality, using a scale that considered internal and external validity criteria, with a maximum score of 30 points. Nine articles were selected, with a methodological quality varying from 12 to 21 points. The studies assessed 68 variables; 35 of which were associated with MIB. The characteristics associated with MIB found in two or more studies were: primiparity, higher level of schooling and older maternal age, prior experience with breastfeeding, not smoking, and living with a partner. Knowledge of the characteristics associated with MIB represents a fundamental step in the planning of actions that seek to increase the duration of breastfeeding.

Prevalence and factors associated with cracked nipples in the first month postpartum.

BACKGROUND: To assess the prevalence and factors associated with the occurrence of cracked nipples in the first month postpartum. METHODS: This was a cross-sectional study nested in a cohort of mothers living in Feira de Santana, state of Bahia, northeastern Brazil. Data from 1,243 mother-child dyads assessed both at the maternity ward and 30 days after delivery were analyzed. The association between cracked nipples as reported by mothers and their possible determinants was analyzed using Poisson regression in a model where the variables were hierarchically organized into four levels: distal (individual characteristics), distal intermediate (prenatal characteristics), proximal intermediate (delivery characteristics), and proximal (postnatal characteristics). RESULTS: The prevalence of cracked nipples was 32 % (95 % confidence interval [95 % CI] 29.4-34.7) in the first 30 days postpartum. The following factors showed significant association with the outcome: poor breastfeeding technique (prevalence ratio [PR] = 3.18, 95 % CI 2.72-3.72); breast engorgement (PR = 1.70, 95 % CI 1.46-1.99); birth in a maternity ward not accredited by the Baby-Friendly Hospital Initiative (PR = 1.51, 95 % CI 1.15-1.99); cesarean section (PR = 1.33, 95 % CI 1.13-1.57); use of a feeding bottle (PR = 1.29, 95 % CI 1.06-1.55); and higher maternal education level (PR = 1.23, 95 % CI 1.04-1.47). CONCLUSIONS: The prevalence of cracked nipples was high in our sample. Most of the factors associated with cracked nipples were related to postnatal characteristics, especially poor breastfeeding technique, which could be improved to help prevent the condition.
