Association between breast-feeding practices and sucking habits: A cross-sectional study of children in their first year of life

In addition to providing nutrition and immunological protection, breast-feeding has positive effects on the development of the infant's oral cavity. The aim of the present study is to assess breast-feeding patterns and to analyze the influence of breast-feeding practices and maternal sociodemographic variables on the prevalence of non-nutritive sucking habits in a sample of Brazilian infants. This cross-sectional study was carried out in Southern Brazil. A random sample of 100 mothers of infants up to 12 months of age was interviewed during the National Vaccination Campaign Day. The prevalence and median duration of breast-feeding were assessed. Breast-feeding practice, the exposure factor, was categorized as exclusive breast-feeding, predominant breast-feeding, complementary breast-feeding, or weaning. Maternal sociodemographic variables included age, race, marital status, educational level, profession, and family income. The outcome investigated was the prevalence of sucking habits (pacifier use and thumb sucking). We used two-sample tests, the chi-square test and Fisher exact test0 for statistical analyses of the data. The study revealed that 75% of infants were being breast-fed. Pacifier use and thumb sucking were common in 55%. Bottle-feeding was prevalent in 74% of infants. Breast-feeding was negatively correlated with pacifier use and thumb sucking (OR = 0.11; 95% CI: 0.03 to 0.4). Bottle-feeding was strongly associated with weaning (p = 0.0003). Among the sociodemographic variables, only marital status showed a statistical association with sucking habits (p = 0.04). These findings suggest that breast-feeding can prevent the occurrence of sucking habits. Although we could not evaluate causality assessment, malocclusion prevention seems to be yet one more reason for promoting breast-feeding practices.

Prevalence and risk factors associated with wheezing in the first year of life

Objective: to investigate the prevalence and risk factors associated with wheezing in infants in the first year of life.Methods: this was a cross-sectional study, in which a validated questionnaire (Estudio Internacional de Sibilancias en Lactantes - International Study of Wheezing in Infants - EISL) was applied to parents of infants aged between 12 and 15 months treated in 26 of 85 primary health care units in the period between 2006 and 2007. The dependent variable, wheezing, was defined using the following standards: occasional (up to two episodes of wheezing) and recurrent (three or more episodes of wheezing). The independent variables were shown using frequency distribution to compare the groups. Measures of association were based on odds ratio (OR) with a confidence interval of 95% (95% CI), using bivariate analysis, followed by multivariate analysis (adjusted OR [aOR]).Results: a total of 1,029 (37.7%) infants had wheezing episodes in the first 12 months of life; of these, 16.2% had recurrent wheezing. Risk factors for wheezing were family history of asthma (OR = 2.12; 95% CI: 1.76-2.54) and six or more episodes of colds (OR = 2.38; 95% CI: 1.91-2.97) and pneumonia (OR = 3.02; 95% CI: 2.43-3.76). For recurrent wheezing, risk factors were: familial asthma (aOR = 1.73; 95% CI: 1.22-2.46); early onset wheezing (aOR = 1.83; 95% CI: 1.75-3.75); nocturnal symptoms (aOR = 2.56; 95% CI: 1.75-3.75), and more than six colds (aOR = 2.07; 95% CI 1.43-.00).Conclusion: the main risk factors associated with wheezing in Fortaleza were respiratory infections and family history of asthma. Knowing the risk factors for this disease should be a priority for public health, in order to develop control and treatment strategies. (C) 2013 Sociedade Brasileira de Pediatria.

A dental caries preventive program applied to children aged 5 to 8 years attending since the first year of age at the Baby Clinic of the Araçatuba Dental School, Brazil

Objective: Tooth decay is one of the more common diseases of childhood. Several studies recommend that early preventive measures must be implemented since the first years of life and continue throughout childhood and adolescence. The aim of the this study was to present results of a preventive dental program considering oral health maintenance, dental caries experience and the prevalence of dental caries relation with follow-up compliance visits. Material end method: Intraoral and interproximal radiographic exams were performed on 171 patients participants of a preventive dental program. Data regarding age, gender, previous caries experience and the frequency at which the patients attended return visits were obtained from the records. The data were analyzed statistically by the McNemar test, with the level of significance set at 1%. Result: Clinical and radiographic examination revealed that most children participating in the program had sound teeth (77.2 and 84.8%, respectively). The past dental history of the dental caries from patients included in this study showed statistical relevance when associated with the present dental caries experience and a statistical relationship was found from the absence of compliance to clinical visits and the dental caries presence. Conclusion: The preventive strategy had a positive influence on oral health maintenance in the children examined. Previous caries experience and the lack of compliance with return visits influenced the clinical oral condition of the children during participation in the preventive program.

Avaliação da atenção ao recém-nascido de risco, na perspectiva de uma política pública de saúde

Objetivou-se avaliar a atenção à saúde de recém-nascidos de risco, acompanhados no primeiro ano de vida pelo Programa Crescer Feliz, desenvolvido em município do interior paulista. Trata-se de estudo epidemiológico populacional, do tipo avaliação de programa de saúde, que se baseou, para análise dos dados, nas diretrizes nacionais da Agenda de Compromissos da Criança. Os resultados evidenciaram a vulnerabilidade institucional do programa, decorrente de problemas relacionados à estrutura e processo, com implicações nos resultados. Considerando a adequação dos critérios adotados pelo programa, para definição dos recém-nascidos de risco e das intervenções e estratégias propostas, que se mostram em consonância com a Agenda de Compromissos, aponta-se a necessidade dos gestores priorizá-lo, inserindo-o, efetivamente, na política pública de saúde a ser desenvolvida no âmbito do município, para reversão da vulnerabilidade institucional identificada.

Contribuição para o conhecimento da biologia de Cynoscion jamaicensis (Vaillant & Bocourt, 1883), na área entre Cabo de São Tomé (22º04's) e Torres (29º21'S), Brasil

Este trabalho baseia-se na análise de dados obtidos de 1891 exemplares de Cynoscion jamaicensis coletados durante quatro cruzeiros oceanográficos realizados por intermédio do N/Oc. Prof. W. Besnard, na área entre Cabo de Sao Tomé (22º04'S) e Torres (29º30'S), até a isóbata de 200 m, dentro do programa FAUNEC. A espécie distribui-se ao longo da plataforma continental, preferencialmente na região banhada pela agua costeira, com temperaturas entre 27ºC e 18ºC. Ocorrem concentrações de jovens e adultos, indiscriminadamente da distância da costa; os jovens ocorreram, em fevereiro-março, entre 22ºS e 27ºS e, nos demais períodos, entre 23º20'S e 27º30'S, enquanto os adultos distribulram-se, em fevereiro-março e maio, entre 26ºS e 27º30'S e, em setembro e novembro, entre 23ºS e 29º30'S. A desova ocorre entre as latitudes 24º30'S e 26º30'S, durante o fim do inverno-primavera (setembro-novembro). Concordando com o ciclo reprodutivo, o fator de condição mostrou variações cíclicas, com valor mais baixo durante setembro, período de desova. O pico de recrutamento verificou-se em maio, quando ocorreram indivíduos com comprimento total entre 70 e 90 mm, provenientes da desova do ano anterior, que ainda nao completaram um ano de idade. 0 comprimento médio de início da primeira maturação sexual é de 154 mm, sendo que aos 200 mm todos os indivíduos estão aptos para a reprodução. A relação peso total/comprimento total apresentou diferenças estatisticamente significativas entre sexos, com α = 3,25 para machos e 3,10 para fêmeas.

Dental caries experience in children attending an infant oral health program

Aim: To investigate: a) caries experience in 5 year-old children and its relationship to the caries risk evaluation made before 1 year of age; b) compliance of parents to an infant oral health program as well as the abandonment reasons. Methods: Group A (GA) - 242 children (60-71 months old) who stayed in the program and had been enrolled since their first year of life underwent a clinical examination according to the WHO's criteria; their parents/caregivers were interviewed to ascertain their compliance to the program. Group B (GB) - parents of 60 children, who had dropped out of the program, were interviewed to check the reasons of withdrawing. The caries risk classification was based on the file at the first appointment. Chi-square test was used (α=0.05) for statistical analyses. Results: Most of the children were free of caries (71.1%). Caries risk evaluation showed low sensibility (34.3%, 95% CI = 22.4-46.1) and high specificity (74.4%, 95% CI = 67.6-81.2) to caries experience. Sixty-two mothers (25.6%) reported difficulty to follow the guidelines. The main reason for dropping out was changing to similar health services (40.0%). Conclusions: Caries risk in the first year of life was not efficient to predict dental caries experience at 5 years of age. Educational practice should be improved to increase the compliance of the parents to the program.

Formação docente e o ensino da educação física junto às crianças com 6 anos de idade no 1º ano do ensino fundamental: a perspectiva dos professores de educação física

Since there are few physical education teachers working in kindergarten, now, due to the elementary school for nine years - getting children 6 years of age, this seems to be a challenge for teachers. Therefore, interested in mobilizing efforts to understand how your training is on this new context, and how is this entry of students from 6 years old in elementary school. From the perspective of the physical education teacher who is acting in this context. In this sense, the objective of this study was to analyze teacher training and teaching of physical education among children 6 years of age entering the first grade of elementary school from the perspective of physical education teachers who work in this field. This study was guided by the principles of qualitative research, making the collection through semi-structured interview, 11 participated in the investigation of physical education teachers working in the first grade of elementary school. The categories of analysis that have emerged from our study were: 1 Teacher training; 2 The 9-year elementary school for children 6 years of age; 3 Teaching physical education in early childhood education: Reflections on its limits and its possibilities. We can point out that physical education in school is still recognized as unimportant, although the LDB 9394/96 art. 26 § 3, have given your requirement, this is not enough to change the scenario that presents itself. School is still considered by many as a space in which the body is separated from the cognitive. Therefore, for many, the play of children is worthless and physical education is worthless. Teachers interviewed here reveal that has focused efforts on making a better quality of physical education, especially among children 1 year, trying to meet their expectations and need characteristics of the universe of childhood

Predictors of first-year survival in patients with advanced COPD treated using long-term oxygen therapy

Little evidence-based guidance is available to aid clinicians in determining short-term prognoses in very severe COPD patients. Therefore, the present study was designed to provide a prospective assessment (1) of the mortality rates and (2) whether the baseline measurements may be determinants of 1-year mortality in hypoxemic COPD patients receiving long-term oxygen therapy (LTOT).Seventy-eight clinically stable patients with advanced COPD treated using LTOT were enrolled in a prospective cohort study. Outcome variable: first-year mortality. Baseline measurements: categorical variables: age (<60 or >= 60 years); gender; body mass index (<20 or >= 20 kg/m(2)); fat-free mass (FFM) index (<16 [men] and <15kg/m(2) [women]; baseline dyspnea index (BDI) (<= 3 or >3); and corticosteroid use. Continuous variables: smoking history; lung function; FFM; fat mass; hemoglobin; hematocrit; arterial blood gases; forearm muscle strength; St. George's Respiratory Questionnaire (SGRQ); and comorbidity score. By the end of 1-year of follow-up, 12 patients (15.4%) had died. Kaplan-Meier curves showed that BDI <= 3 was the only variable associated with higher mortality. Cox proportional hazards analysis revealed that tower PaO2 and SPO2, higher PaCO2 and SGRQ scores were associated with reduced survival. In the multivariate analysis, BDI remained predictive of mortality (hazard ratio [HR], 0.50; 95% confidence interval [CI], 0.31-0.81), as did PaO2 (HR, 0.49; 95% CI, 0.26-0.95). These data suggest that readily available parameters as dyspnea intensity and hypoxemia severity may be useful in predicting first-year survival rates in advanced COPD patients receiving LTOT (C) 2007 Elsevier Ltd.

Seasonal metabolic depression, substrate utilisation and changes in scaling patterns during the first year cycle of tegu lizards (Tupinambis merianae)

The tegus increase in body mass after hatching until early autumn, when the energy intake becomes gradually reduced. Resting rates of oxygen consumption in winter drop to 20% of the values in the active season (Vo(2)=0.0636 ml g(-1) h(-1)) and are nearly temperature insensitive over the range of 17-25degreesC (Q(10)=1.55). During dormancy, plasma glucose levels are 60% lower than those in active animals, while total protein, total lipids and beta-hydroxybutyrate are elevated by 24%, 43% and 113%, respectively. In addition, a significant depletion of liver carbohydrate (50%) and of fat deposited in the visceral fat bodies (24%) and in the tail (25%) and a slight loss of skeletal muscle protein (14%) were measured halfway through the inactive period. Otherwise, glycogen content is increased 4-fold in the brain and 2.3-fold in the heart of dormant lizards, declining by the onset of arousal. During early arousal, the young tegus are still anorexic, although Vo(2) is significantly greater than winter rates. The fat deposits analysed are further reduced (62% and 45%, respectively) and there is a large decrease in tail muscle protein (50%) together with a significant increase in glycogen (2-3-fold) and an increase in plasma glucose (40%), which suggests a role for gluconeogenesis as a supplementary energy source in arousing animals. No change is detectable in citrate synthase activity, but beta-hydroxyacyl CoA dehydrogenase activities are strongly affected by season, reaching a Mold and 5-fold increase in the liver tissue of winter and arousing animals, respectively, and becoming reduced by half in skeletal muscle and heart of winter animals compared with late fall or spring active individuals. From hatching to late autumn, the increase of the fat body mass relatively to body mass is disproportionate (b=1.44), and the mass exponent changes significantly to close to 1.0 during the fasting period. The concomitant shift in the Vo(2) mass exponent in early autumn (b=0.75) to values significantly greater than 1.0 in late autumn and during winter dormancy indicates an allometric effect on the degree of metabolic depression related to the size of the fat stores and suggests greater energy conservation in the smaller young.
