ResumoObjetivo: Revisar a literatura científica e leiga sobre o treinamento esfincteriano, abordando expectativas dos pais, métodos disponíveis para aquisição do controle esfincteriano e morbidades associadas. Fontes dos dados: Síntese dos dados:Os pais apresentam expectativas irreais sobre idade de retirada de fraldas, sem levar em conta o desenvolvimento infantil. As estratégias de treinamento não se modificaram nas últimas décadas, e a idade vem sendo postergada na maioria dos países. Métodos de treinamento raramente são utilizados. O início precoce do treinamento esfincteriano e eventos estressantes durante o período podem prolongar o processo de treinamento. Uma maior freqüência de enurese, infecção urinária, disfunção miccional, constipação, encoprese e recusa em ir ao banheiro é observada nas crianças com treinamento inadequado. A literatura leiga para os pais é abundante e adequada, veiculada através de livros e da Internet, mas não largamente disponível para a população brasileira. Apenas três sociedades internacionais de pediatria disponibilizam diretrizes sobre treinamento esfincteriano. Conclusões:O controle esfincteriano vem sendo postergado na maioria dos países. Os métodos de treinamento existentes são de décadas passadas, sendo pouco utilizados pelas mães e pouco valorizados pelos pediatras; o treinamento inadequado pode ser um dos fatores causadores de distúrbios miccionais e intestinais, que causam transtornos para as crianças e famílias.J Pediatr (Rio J). 2008;84(1):9-17: Treinamento para uso de toalete, enurese, criança, infecção urinária, transtornos da excreção. AbstractObjective: To review both the scientific literature and lay literature on toilet training, covering parents' expectations, the methods available for achieving bladder and bowel control and associated morbidities. Sources:Articles published between 1960 and 2007, identified via the MEDLINE, Cochrane Collaboration, ERIC, Web of Science, LILACS and SciELO databases plus queries on the Google search engine; a search of related articles, references of articles, by author and of pediatrics societies. A total of 473 articles were examined and 85 of these were selected for this review. Summary of the findings:Parents have unrealistic expectations about the age at which diapers can be withdrawn, not taking child development into account. Toilet training strategies have not changed over recent decades, and in the majority of countries the age at which children are trained has been postponed. Training methods are rarely used. Starting toilet training prematurely and stressful events during this period can extend the training process. Children who have not been trained correctly present with enuresis, urinary infection, voiding dysfunction, constipation, encopresis and refusal to go to the toilet more frequently. Literature intended for lay parents is both abundant and adequate, available in book form and on the Internet, but it is not widely available to the Brazilian population. Just three international pediatrics societies have publ...

BackgroundWe assessed anthropometric status, breastfeeding duration, morbidity, and mortality outcomes during the first four years of life according to gestational age, in three population-based birth cohorts in the city of Pelotas, Southern Brazil.MethodsTotal breastfeeding duration, neonatal mortality, infant morbidity and mortality, and anthropometric measures taken at 12 and 48 months were evaluated in children of different gestational ages born in 1982, 1993 and 2004 in Southern Brazil.ResultsBabies born <34 weeks of gestation and those born between 34–36 weeks presented increased morbidity and mortality, were breastfed for shorter periods, and were more likely to be undernourished at 12 months of life, in comparison with the 39–41 weeks group. Children born with 37 weeks were more than twice as likely to die in the first year of life, and were also at increased risk of hospitalization and underweight at 12 months of life. Post-term infants presented an increased risk of neonatal mortality.ConclusionThe increased risks of morbidity and mortality among preterm (<37 weeks of gestation) and post-term (>41 weeks) are well known. In our population babies born at 37 also present increased risk. As the proportion of preterm and early term babies has increased markedly in recent years, this is a cause for great concern.

ResumoObjetivos: O aprendizado do controle esfincteriano é influenciado por fatores fisiológicos, psicológicos e socioculturais. O objetivo deste estudo foi avaliar a prevalência de crianças sem fraldas aos 24 meses e seus fatores associados.Métodos: Um total de 3.281 crianças nascidas no ano de 2004 em Pelotas (RS) foi incluído em um estudo longitudinal. Aos 24 meses, as mães responderam a um questionário domiciliar com questões sociodemográficas, características dos hábitos miccionais e intestinais das crianças, com atenção ao treinamento esfincteriano. Foi empregada a regressão de Poisson para as análises multivariáveis.Resultados: Do total, 24,3% estavam sem fraldas durante o dia, com predomínio do sexo feminino (27,8 versus 21,1%, p < 0,001) e 8,6% sem fraldas durante a noite, também com predomínio do sexo feminino (10,6 versus 6,8%, p < 0,001). As habilidades necessárias ao aprendizado do controle esfincteriano estavam presentes em 85,5% das crianças. Orientação pediátrica ocorreu em 10% das crianças, mais freqüente nas mães mais ricas em relação às mais pobres (22,9 versus 4,8%). Mães mais escolarizadas (13,2%) e mais ricas (14%) retiram as fraldas mais tardiamente; maior número de crianças em casa (risco relativo = 1,32) e indicar a necessidade de ir ao vaso (risco relativo = 11,74) aumentam a probabilidade de retirar as fraldas; tentativa anterior sem sucesso retarda a retirada de fraldas (risco relativo = 0,59).Conclusões: Embora as habilidades necessárias para a aquisição do controle esfincteriano já estejam presentes aos 24 meses, indicando que um treinamento esfincteriano pode ser iniciado, a maioria das crianças ainda não tinha iniciado esse treinamento. As mães com melhor nível de informação retardam mais esse treinamento.J Pediatr (Rio J). 2008;84(5):455-462: Treinamento de toalete, crianças, controle esfincteriano, disfunção miccional. AbstractObjectives: Acquisition of bladder and bowel control is influenced by physiological, psychological and sociocultural factors. The objective of this study was to evaluate the prevalence of children out of diapers by 24 months of age and the factors associated with this finding.Methods: A total of 3,281 children born in Pelotas, RS, Brazil in 2004 were enrolled on a longitudinal study. At 24 months their mothers were visited at home and replied to a questionnaire containing questions about sociodemographic data and the characteristics of their children's urinary and intestinal evacuation habits, with special attention to toilet training. Multivariate analyses were carried out using Poisson regression.Results: From the total, 24.3% were out of diapers during the day, with the female sex predominating (27.8 vs. 21.1%, p < 0.001) and 8.6% were out of diapers at night, also with the female sex predominating (10.6 vs. 6.8%, p < 0.001). The abilities needed to start toilet training were present in 85.5% of the children. Guidance was received from a pediatrician in 10% of cases, and more frequently among richer mothers than among poorer mothers (22.9 vs. 4.8%). Mot...

Objective: To describe voiding patterns and related dysfunctions in a population-based sample of children aged 3 to 9 years. Methods:A cross-sectional population-based survey including 580 children. A probabilistic sample of households in the urban area of Pelotas in southern Brazil was selected following a multiple-stage protocol. Voiding and fecal patterns were investigated using the dysfunction score created by Farhat et al. and modified by the addition of high urinary frequency (more than eight times a day). Boys with scores above eight and girls above five were clinically investigated, as well as a sub-sample of the remaining children.Results: Nocturia (60.4%), urinary urgency (49.7%) and holding maneuvers (42.1%) were the most frequently reported symptoms. The prevalence of enuresis was 20.1% in boys and 15.1% in girls. The prevalence of urinary dysfunction was 22.8%. Most symptoms were more frequently reported by girls and younger children. Among girls, low socioeconomic level was related to an increased prevalence of enuresis and straining to urinate, while among boys urgency was more common among the poor. Only 10.5% of the parents of the children with voiding dysfunction consulted a doctor because of their problems. Conclusions:The voiding symptoms studied presented high prevalence rates, and therefore should be investigated in clinical practice, with direct questions about each symptom, aiming to diagnose voiding dysfunction.

ObjectiveTo investigate the association between bedsharing at age 3 months and breastfeeding (BF) at age 12 months.Study designAlmost all children born in Pelotas, Brazil in 2004 (99.2%) were enrolled in a cohort study. At birth, age 3 months, and age 12 months, mothers were interviewed to gather information on sociodemographic, reproductive, BF, and bedsharing characteristics. Bedsharing was defined as habitual sharing of a bed between mother and child for the entire night or part of the night. The analysis was limited to children from single births who were breastfed at 3 months. Multivariate analyses were carried out using Poisson regression.ResultsOf 4231 live births, 2889 were breastfed at age 3 months. The prevalence of BF at age 12 months was 59.2% in the children who bedshared at 3 months and 44% in those who did not (adjusted prevalence ratio [PR] for weaning= 0.75; 95% confidence interval [CI] = 0.69-0.81; P < .001). Among children who were exclusively breastfed at 3 months, 75.1% of those who also bedshared were still breastfed at age 12 months, versus 52.3% of those who did not bedshare (adjusted PR = 0.63; 95% CI = 0.53- 0.75; P < .001). The adjusted PR was 0.74 (95% CI = 0.60-0.90; P = .003) in children who were predominantly breastfed and 0.83 (95% CI = 0.76-0.90; P < .001) in those who were partially breastfed.ConclusionsBedsharing at 3 months protected against weaning up to age 12 months.

We studied time trends in infant mortality and associated factors between three cohort studies carried out in Pelotas, Rio Grande do Sul State, Brazil, in 1982

Enuresis is a prevalent condition and should be investigated in clinical practice, especially in children of lower socioeconomic status. A detailed history of urinary habits detects associated urinary symptoms, which is important for adequate classification of enuresis and subsequent management.

The prevalence of constipation increases with age and cannot be detected using only information on evacuation interval. Toilet training before 24 months and introduction of cow's milk before 1 year of age is positively associated with constipation at 24 months and its persistence up to 48 months.
