Prevalence and risk factors of lower urinary tract symptoms in rural children and adolescents / 现代泌尿外科杂志

【Objective】 To investigate the prevalence and risk factors of lower urinary tract symptoms (LUTS) in rural children and adolescents. 【Methods】 An epidemiological LUTS survey was carried out on 4 100 children and adolescents (aged 6-16 years) in five primary and secondary schools in rural Henan by means of stratified random cluster sampling using anonymous questionnaires. Daytime urinary incontinence (DUI), nocturnal enuresis (NE), and postnatal diaper use and toilet training were investigated. 【Results】 A total of 3 885 valid questionnaires were recovered (with a recovery rate of 94.76%). The total prevalence of the four symptoms of LUTS, including urgency, frequency, DUI and NE, were 16.42%, 10.91%, 7.41% and 7.95%, respectively. As much as 21.13% subjects had at least one symptom. The prevalence of the four symptoms decreased gradually with age, decreased sharply in those aged 6 to 12 years, and then decreased slowly. The prevalence of LUTS in children who stopped using diapers and stared urine training after 1 year of age was significantly higher than that of those within 1 year of age (χ2=21.605, 23.111, 24.189, 23.509, all P<0.05; χ2=102.17, 72.168, 53.656, 197.76, all P<0.05). There were significant differences in the prevalence of LUTS between those with and without toilet training (χ2=315.273, 198.438, 105.723, 272.502, all P<0.05). The prevalence of LUTS in males was significantly higher than that in females (P<0.05). Constipation, prepuce and phimosis in boys were significantly associated with the prevalence of LUTS (P<0.05). 【Conclusion】 Rural children and adolescents have a high prevalence of LUTS. Diaper use after 1 year of age, history of urinary tract infection (UTI), lack of toilet training, constipation, and abnormal prepuce are risk factors of LUTS. Urine training before 1 year of age is a protective factor of LUTS.

Relationship between primary monosymptomatic enuresis and process toilet training: a case-control

ABSTRACT Objective: Primary monosymptomatic nocturnal enuresis (PMNE) is a prevalent condition in childhood, and the pathophysiology is multifactorial. This study investigated the relationship between the toilet training process (TT) and PMNE in children and adolescents. Patients and Methods: A case-control study was carried out from 2015 to 2020. The presence of PMNE was identified according to International Children's Continence Society criteria. A semi-structured questionnaire was applied to assess TT. Results: The study included 103 children and adolescents with PMNE and 269 participants with normal psychomotor development without PMNE (control group [CG]). Readiness signals were more remembered and less frequent in participants with PMNE (p=0.001) when compared to control group. No differences were found between the groups regarding the onset age of the daytime TT (p= 0.10), the nocturnal TT (p=0.08), the acquisition of daytime continence (p=0.06), and the type of equipment used for the TT (p=0.99). The use of Child-Oriented approach in group of children with enuresis was lower than in controls [87.4% (90/103) versus 94% (250/266)], respectively (OR= 0.44, 95% CI 0.21-0.94, p = 0.039). Conclusions: The age of onset of TT, acquisition of daytime continence, and the type of equipment were not associated with higher occurrence of PMNE. On the other hand, the Child-Oriented approach was a protective factor for the occurrence of PMNE.

Personal and familial factors associated with toilet training

ABSTRACT Purpose: Toilet training (TT) is an important marker in a child's physical and psychosocial development. The present study aimed to evaluate aspects associated to delayed TT. Material and Methods: We interviewed 372 parents of children who had completed TT up to 48 months before the interview. The questionnaires were applied at school exits when parents went to pick their children up and at public parks. Questions included demographics, aspects related to TT, dysfunction voiding symptom score and evaluation of constipation. Results: The interviews were performed at a mean of 15.3±10.4 (0 to 47) months after the end of TT. Girls accounted for 53% of the sample. The mean age at finishing TT was 31.6±9.3 months and similar in both genders (p=0.77). TT occurred before school entry in 45.7% of the children and medical advice for TT was sought only by 4.8% of the parents. No association was observed of age at completing TT and presence of lower urinary tract symptoms (LUTS) (p=0.57) and/or constipation (p=0.98). In the univariate analysis, prematurity (OR=2.7 [95% CI 2.3-3.1], p <0.0001) and mothers who work outside their household (OR=1.8 [95% CI 1.4-2.3], p <0.0001) were associated to delayed TT. Conclusion: Children completed TT at a mean of 2 years and 7 months of age. The age of completing TT was not related to LUTS and/or constipation. Premature children and those whose mothers work outside the home finish TT later.

Are We Educating, Our Children, About Hygiene? Are We Talking, With Them, About It?

Cancer screening has always focused on screening lone individuals even when sexually transmitted diseases (STDs) have been traditionally known to require concurrent treatment of all current sexual partners. This shared responsibility towards the sexual partners cannot be limited only to the prevention and treatment of STDs, especially when human papillomavirus (HPV), which is a STD, has been implicated in the etio-pathogenesis of cervical, penile and anal cancers besides other perineal cancers. Consequently, educating Indian population about our personal perineal hygienic practices is of utmost importance to help curtailing the non-“contagious” spread of cancers.

Prolonged toilet training in children with Down syndrome: a case-control study / Treinamento esfincteriano em crianças com síndrome de Down: estudo caso-controle

Abstract Objectives Children with Down syndrome have delayed psychomotor development, which is a factor that influences the level of difficulty in toilet training. The current study aims to estimate the age toilet training starts and completes in children with DS compared to children with normal psychomotor development and to evaluate the method and type of toilet training most frequently used, as well as its association with lower urinary tract symptoms and functional constipation. Methods A case-control study was carried out from 2010 to 2015. All parents completed a questionnaire designed to assess the toilet training process. Lower urinary tract symptoms were assessed through the application of the Dysfunctional Voiding Symptom Score. The presence of functional constipation was assessed according to the Rome III criteria. Results The study included 93 children with Down syndrome and 204 children with normal psychomotor development (control group [CG]). The mean age of toilet training onset was 22.8 months in those with DS and 17.5 months in the CG (p = 0.001). In children with DS, the mean age when completing toilet training was 56.2 months and 27.1 months in the CG (p = 0.001). Among children with DS, females completed toilet training earlier (p = 0.02). The toilet training method used most often was child-oriented approach in both groups. No association was observed with the presence of lower urinary tract symptoms or functional constipation and the age of beginning and completing toilet training in both groups. Conclusion Children with Down syndrome experienced prolonged toilet training time. Prospective longitudinal studies are essential to gain insight into the toilet training of these children.

Métodos Um estudo caso-controle foi realizado de 2010 a 2015. Todos os pais preencheram um questionário destinado a avaliar o processo de treinamento esfincteriano. O sintomas do trato urinário inferior foram avaliados por meio da aplicação do Dysfunctional Voiding Symptom Score. A presença de constipação funcional foi avaliada de acordo com os critérios Roma III. Resultados O estudo incluiu 93 crianças com síndrome de Down e 204 crianças com desenvolvimento psicomotor normal (Grupo de Controle [GC]). A idade média em que as crianças iniciaram o treinamento esfincteriano foi de 22,8 meses naquelas com SD e 17,5 meses no GC (p = 0,001). Em crianças com SD, a idade média ao concluir o treinamento esfincteriano foi de 56,2 meses e 27,1 meses no GC (p = 0,001). Entre as crianças com SD, as do sexo feminino concluíram o treinamento esfincteriano mais cedo (p = 0,02). O método de treinamento esfincteriano mais utilizado foi a abordagem voltada para a criança em ambos os grupos. Não houve associação com a presença de sintomas do trato urinário inferior ou constipação funcional e a idade no início e na conclusão do treinamento esfincteriano em ambos os grupos. Conclusão Crianças com síndrome de Down apresentaram tempo de treinamento esfincteriano prolongado. Estudos longitudinais prospectivos são essenciais para obter uma visão do treinamento esfincteriano dessas crianças.

Effect of urinary training on urination control of infants using nappies after birth / 中华实用儿科临床杂志

Objective To investigate the effect of urinary training on urination control in infants using nappies after birth.Methods Stratified sampling method was used to investigate the daytime urination control and the using of diapers by children in kindergartens of 6 prefecture-level cities in Henan Province,China.The survey was conducted among parents of healthy children.Results In a total of 12 250 questionnaires,11 697 had response,and 10 562 valid questionnaires were collected,and the effective recovery rate was 86.22％.After the birth of infants,the age of toilet training was divided into 6 groups (0-＜ 3 months old group,3-＜ 6 months old group,6-＜ 12 months old group,12-＜ 18 months old group,18-＜ 24 months old group and no toilet training group).Results showed that toilet training within 12 months leads to higher urinary control rate compared with toilet training after 12 months and no toilet training till the age of 2 years old,70.56％ (4 831/6 847 cases) in contrast with 59.02％ (1 545/2 618 cases) and 42.48％ (466/1 097 cases),and the differences were statistically significant (x2 =114.76,335.48,all P ＜ 0.000 1).Within 12 months,there was no statistical difference in the urinary control rate between subgroups at 2 years of age(all P ＞0.05).After 12 months,the urination control rate decreased with the start time delayed till 2 years of age,and the urinary control rate at the age of 2 years old n different groups was 59.97％ (1 314/2 191 cases) and 54.10％ (231/427 cases) respectively.The results of other ages(0.5,1.0,1.5 years old) were similar to those of 2 years old.There was no difference between the groups of different genders (all P ＞ 0.05).Conclusions The use of diapers in infants before the age of 1 year to start urinary training is conducive to the development of urinary control in infants.

Analysis of the compliance of defecation function training of patients with ultra-low rectal cancer ;after intersphincteric resection / 中国实用护理杂志

Objective To analyze the compliance of defecation function training of patients with ultra- low rectal cancer after intersphincteric resection and the influencing factors. And therefore to provide theoretical reference for the problems and nursing management of training. Methods The study was a reviewing trial. The enterostomal therapist educated patients with ultra-low rectal cancer after intersphincteric resection. Research used the basic information questionnaire, compliance evaluation of defecation function training, defecation diary and Fecal Incontinence Quality of Life Questionnaire as research instruments. And statistical analysis was used to acquired data. Results The score of the defecation function training compliance was (67.67 ± 5.28) points; Anal function and the fecal incontinence quality of life was in negative correlation with the compliance; At 9 and 12 months, anal function of patients who had good compliance were obviously improved (P < 0.05). Factors such as complications, internal sphincterotomy, operation, degree of education, pathologic stage, payment of medical expenses were related to the compliance (P < 0.05 or 0.01); The correlation analysis demonstrated that the compliance decreased with time. Conclusions The compliance of defecation function training of patients is related to anal function and the fecal incontinence quality of life. A effective training program and follow- up appointment is very important. Nurses should provide psychological counseling and health education for them to boost confidence improve quality of life.

Fecal Retention in Overactive Bladder (OAB) in Children: Perspective of a Pediatric Gastroenterologist

Coexisting voiding and bowel dysfunction in children are common in the clinic. The idea that overactive bladder (OAB) and constipation arise from one single pathophysiology has been reinforced in many studies. In Korea, a nationwide multicenter study conducted in 2009 showed that overall prevalence of OAB in children, 5-13 years of age, was 16.59% and this number has increased more recently. The initial step to manage coexisting fecal retention and OAB in children is to characterize their bowel and bladder habits and to treat constipation if present. Although diagnosing constipation in children is difficult, careful history-taking using the Bristol Stool Form Scale, and a scoring system of plain abdominal radiography, can help to estimate fecal retention more easily and promptly. Non-pharmacological approaches to manage functional constipation include increasing fluids, fiber intake, and physical activity. Several osmotic laxatives are also effective in improving OAB symptoms and fecal retention. Additionally, correction and education in relation to toilet training is the most important measure in treating OAB with fecal retention.

Implantación de estimulador de raíces sacras anteriores: experiencia e implicaciones del manejo anestésico / Implantation of sacral anterior roots stimulator: Experience and implications for the anesthetic management

Introducción: La vejiga neurogénica predispone a los pacientes con traumatismo raquimedular a incontinencia refleja, infecciones del tracto urinario, disreflexia autonómica y fallo renal, el cual es una de las principales causas de mortalidad. La neuromodulación de las raíces sacras anteriores es un tratamiento de la disfunción vesical. Es raro encontrar publicaciones en anestesiología sobre este procedimiento. Objetivos:Describir el comportamiento hemodinámico y los efectos adversos durante el intraoperatorio y post-operatorio inmediato en los pacientes que han recibido implantación de estimulador de raíces sacras anteriores. Métodos: Estudio descriptivo retrospectivo de pacientes con traumatismo raquimedular crónico que han recibido implantación de estimulador de raíces sacras anteriores. Resultados: De 50 pacientes estudiados, el 34% tenían lesión torácica alta, un 58% tenía lesión espinal secundaria a herida por proyectil de arma de fuego, el 40% con antecedente de disreflexia autonómica, el 98% empleo de monitoría con línea arterial, el 90% de los pacientes presentó hipotensión y el 86% requirió manejo vasopresor, el 34% presentó bradicardia y el 88% requirió manejo con atropina. Conclusiones: La hipotensión y la bradicardia son los principales efectos adversos durante el manejo de estos pacientes pero con adecuada respuesta al tratamiento médico. Se deben realizar estudios que evalúen la asociación entre nivel de la lesión con bradicardia e hipotensión y la monitorización ideal durante este procedimiento.

Introduction: Neurogenic bladder predispose to patients with spinal cord injuria to reflex incontinence, urinary tract infections, autonomic dysreflexia and renal failure, which is one of the key causes of mortality. Neuromodulation of the anterior sacral roots is a treatment for bladder dysfunction. The anesthesiology publications about this procedure are very rarely. Objectives: To describe the hemodynamic behavior and the adverse events during the intraoperative and immediate postoperative period of patients undergoing implantation of the sacral anterior roots stimulator. Methods: Retrospective, descriptive study of series of cases of patients with chronic spinal cord trauma implanted with the anterior sacral roots stimulator. Results: Out of 50 patients studied, 34% had an upper chest injury, 58% had a spinal injury secondary to a fire weapon bullet, 40% had a history of autonomic dysreflexia, 98% were had arterial line monitoring, 90% of the patients were hypotensive and 86% required vasopressors; 34% experienced bradycardia and 88% required atropine management. Conclusions: Hypotension and bradycardia are the major adverse events in the management of these patients, but they exhibit adequate response to medical treatment. Studies are needed to assess the association between the level of the injury versus the presence of bradycardia and hypotension and the ideal monitoring during the procedure.

Treinamento esfincteriano anal: estudo transversal em crianças de 3 a 6 anos de idade / Bowel toilet training: a cross-sectional study in children between 3 and 6 years old

OBJETIVO: Avaliar o treinamento do controle esfincteriano anal em crianças, por meio de entrevista aplicada aos pais ou cuidadores. MÉTODOS: Estudo de corte transversal em crianças sadias, aplicando-se um questionário estruturado para 100 responsáveis por crianças entre três e seis anos de idade. RESULTADOS: 97 por cento das crianças foram treinadas em casa pelas mães e 92 por cento delas utilizaram a intuição, a experiência com o filho anterior e o aprendizado com as avós. O treinamento do controle esfincteriano anal e vesical foi iniciado simultaneamente em 84 por cento dos casos, sendo o controle anal adquirido primeiramente em 41 por cento das crianças. As mães com escolaridade menor e das classes C-D-E iniciaram o treinamento mais precocemente, sendo um dos fatores relatados o custo das fraldas. Não houve diferença entre meninos e meninas para idade de início e duração do treinamento. As crianças apresentavam a maioria dos "sinais de prontidão" para o início do treinamento e, das crianças que foram treinadas no vaso sanitário, uma pequena parcela utilizou redutor e apoio para os pés. Não houve aumento significativo de constipação intestinal após o treinamento e não foram observados casos de encoprese. CONCLUSÕES: As mães foram as responsáveis pelo treinamento esfincteriano anal e o iniciaram sem auxílio especializado. Nas classes sociais C-D-E, o custo das fraldas foi determinante para o início do treinamento esfincteriano anal.

OBJECTIVE: To assess the practice of children's toilet training through interviews with parents and caretakers. METHODS: A cross-sectional study of healthy children using a questionnaire applied to parents or caretakers of 100 consecutive children aged 3 to 6 years old. RESULTS: 97 percent of the children were home-trained by their mothers and 92 percent of them used their intuition, previous experience with an older child and grandmothers' experience. Bowel and bladder toilet training started simultaneously in 84 percent of the cases, whereas 41 percent of the children mastered stool control earlier. Mothers with lower educational level and of social classes C, D and E initiated the training earlier and one of the related reasons was the cost of disposable diapers. Age in initiation or duration of toilet training was similar for boys and girls. Children presented most of the "readiness symptoms" for toilet training and only a small number of them used a seat reducer or a foot support. There was no increase in constipation prevalence after toilet training and there was no encopresis. CONCLUSIONS: Mothers were responsible for bowel toilet training and initiated it with no specialized help. In C-D-E social classes, the cost of diapers was determinant to initiate bowel toilet training.

Avaliação longitudinal do controle esfincteriano em uma coorte de crianças Brasileiras / Longitudinal study of sphincter control in a cohort of Brazilian children

OBJETIVOS: Avaliar a trajetória do controle esfincteriano em uma coorte de nascimento. MÉTODO: Quatro mil duzentos e trinta e uma crianças nascidas no ano de 2004, em Pelotas, RS, foram incluídas em um estudo longitudinal. Em visitas domiciliares realizadas aos 12, 24 e 48 meses, as mães responderam a um questionário com questões sociodemográficas, características dos hábitos miccionais e intestinais das crianças, com atenção ao treinamento esfincteriano. RESULTADOS: Aos 48 meses, a maioria das crianças estava sem fraldas durante o dia (98,5 por cento) e à noite (83 por cento), sem diferença entre os sexos. A idade média de início de treinamento esfincteriano foi 22 meses, com início mais precoce nas meninas. A duração média do treinamento foi de 3,2 meses, sem diferença entre os sexos. Crianças com atraso de desenvolvimento apresentaram controle esfincteriano mais tardio, havendo relação direta entre a intensidade do desvio da normalidade e a idade da retirada de fraldas. A orientação médica foi fornecida a 15,9 por cento das mães. O treinamento iniciado antes dos 24 meses esteve relacionado com uma maior idade de controle esfincteriano e maior duração do treinamento. Crianças prematuras ou com baixo peso não apresentaram diferença significativa no tempo de treinamento e idade de aquisição do controle esfincteriano. CONCLUSÕES: Até os quatro anos de idade, a maioria das crianças, inclusive prematuros e de baixo peso ao nascer, obtém controle esfincteriano independentemente de fatores externos e do sexo. O início do treinamento (antes dos 24 meses) não antecipou o controle esfincteriano, apenas prolongou o tempo de treinamento.

OBJECTIVES: To analyze sphincter control acquisition in a birth cohort. METHOD: 4,231 children born in 2004 in Pelotas, Brazil, were included in a longitudinal study. During home visits at the ages of 12, 24 and 48 months, the mothers answered a questionnaire about sociodemographic questions and characteristics of their children's voiding and bowel habits, with special attention to toilet training. RESULTS: At 48 months, most children were off diapers during the day (98.5 percent) and by night (83 percent), with no difference between sexes. The average age for starting toilet training was 22 months, with earlier initiation in girls. The training was, on average, 3.2 months long, showing no difference between sexes. Children with developmental delay had late voiding and bowel control; the higher the deviation from normality, the later the child was off diapers. Medical advice was given to 15.9 percent of mothers. The training initiated before the age of 24 months was inversely correlated with an older age of sphincter control and longer training. Premature and low birth weight children showed no significant difference in training time and age of acquisition of sphincter control. CONCLUSIONS: At the age of 48 months, most children, including premature and low birth weight ones, acquired sphincter control regardless of external factors and sex. The beginning of training (before 24 months) did not anticipate sphincter control, but only prolonged the duration of training.

A study on the toilet training and influencing factors / 소아과

PURPOSE: We aimed to determine the ideal age for initiating toilet training and investigate the factors influencing the training. METHODS: The study population comprised 1,370 children aged 2-6 years, who visited the pediatric clinics in Jeonju, Iksan, and Gunsan. Their parents were given questionnaires in order to gather data about the types of diapers used, ages when toilet training was initiated and completed for each day and night, its adverse effects, and the educational level and employment and economic status of the mothers. RESULTS: The toilet training initiation age was low for those living in the country, having an elder sibling(s), and using cloth diapers, and for those whose mothers were employed and had a low economic status. The training completion age was 22.9 months when the training was initiated before the age of 18 months; this was lower than the training completion ages of 25.9 and 31.0 months when the training was initiated at the age of 18-24 months and after 25 months, respectively. However, the required durations in these cases were 8.4, 5.6, and 3.8 months, respectively. Encopresis and refusal occurred more often when the training was initiated before the age of 18 months than when initiated after this age. CONCLUSION: Toilet training should begin at least after the age of 18 months considering the developmental status of infants. It is recommended for the future researchers to develop specific guidelines regarding toilet training.

Aquisição do controle esfincteriano em uma coorte de nascimentos: situação aos 2 anos de idade / Toilet training: situation at 2 years of age in a birth cohort

OBJETIVOS: 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 por cento estavam sem fraldas durante o dia, com predomínio do sexo feminino (27,8 versus 21,1 por cento, p < 0,001) e 8,6 por cento sem fraldas durante a noite, também com predomínio do sexo feminino (10,6 versus 6,8 por cento, p < 0,001). As habilidades necessárias ao aprendizado do controle esfincteriano estavam presentes em 85,5 por cento das crianças. Orientação pediátrica ocorreu em 10 por cento das crianças, mais freqüente nas mães mais ricas em relação às mais pobres (22,9 versus 4,8 por cento). Mães mais escolarizadas (13,2 por cento) e mais ricas (14 por cento) 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.

OBJECTIVES: 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 percent were out of diapers during the day, with the female sex predominating (27.8 vs. 21.1 percent, p < 0.001) and 8.6 percent were out of diapers at night, also with the female sex predominating (10.6 vs. 6.8 percent, p < 0.001). The abilities needed to start toilet training were present in 85.5 percent of the children. Guidance was received from a pediatrician in 10 percent of cases, and more frequently among richer mothers than among poorer mothers (22.9 vs. 4.8 percent). Mothers who spent more years in education (13.2 percent) and were from higher social classes (14 percent) took their children out of diapers later; a greater number of children living at home (relative risk = 1.32) and being able to communicate the need to go to the toilet (relative risk = 11.74) both increased the probability of being out of diapers; previous unsuccessful attempts delayed removal of diapers (relative risk = 0.59). CONCLUSIONS: Although the abilities needed for acquisition of bladder and bowel control were already present at 24 months, indicating that toilet training could be started, the majority of children had not yet started this training. Better-informed mothers delayed training the most.

Treinamento esfincteriano precoce: prevalência, características materna da criança e fatores associados numa coorte de nascimentos / Early toilet training: prevalence, the characteristics of the mother and of the child and associated factors in a cohort of births

OBJETIVOS: avaliar a prevalência de crianças sem fraldas, a idade de início do treinamento esfincteriano e a expectativa materna em relação à aquisição deste controle numa coorte de nascimentos. MÉTODOS: todas as crianças nascidas em 2004 em Pelotas, Rio Grande do Sul, Brasil, foram incluídas em um estudo longitudinal. Aos 12 meses, as crianças tiveram seu desenvolvimento avaliado e as mães questionadas sobre o início do treinamento esfincteriano e expectativa em relação à idade da retirada das fraldas. Diferenças entre grupos foram avaliadas através de testes qui-quadrado para heterogeneidade e tendência linear. RESULTADOS: aos 12 meses de idade, 14,7 por cento das mães tinham iniciado o treinamento esfincteriano. Apenas 2,2 por cento receberam orientação pediátrica sobre retirada de fraldas. Os grupos de mães com maior prevalência de início de treinamento aos 12 meses foram as do primeiro quintil econômico, cinco a oito anos de escolaridade, adolescentes e maiores de 40 anos. Dois terços acham que o momento para deixar as fraldas é antes dos 18 meses; 1,3 por cento das crianças estão sem fraldas de dia. CONCLUSÕES: o treinamento esfincteriano começou precocemente em uma parcela significativa destas crianças, sendo desprezível a proporção de mães orientadas pelos pediatras. Informações sobre o momento ideal e métodos adequados de controle esfincteriano devem ser oferecidas às mães, no contexto da puericultura e atenção básica à saúde.

OBJECTIVES: to assess the prevalence of children not using diapers, the age at which toilet training started and the mother's expectations regarding the attainment of this in a cohort of births. METHODS: all children born in 2004 in the city of Pelotas, in the State of Rio Grande do Sul, Brazil, were enrolled in a longitudinal study. At the age of 12 months they were assessed for their development. Mothers were questioned regarding the beginning of toilet training and parental expectations in relation to the age at which daytime toilet training should be completed. Differences between groups were assessed using chi-squared tests for heterogeneity and linear tendency. RESULTS: at 12 months of age 14.7 percent of the mothers had begun daytime toilet training. Only 2.2 percent of the mothers were provided guidance by pediatricians regarding cessation of diaper use. The groups of mothers with the higher prevalence of starting toilet training at 12 months were the ones from the top economic quintile, five to eight years of schooling, adolescent mothers and mothers aged over 40 years. Two thirds of the mothers believed the ideal time to cease using diapers is before 18 months of age; 1.3 percent of children did not use diapers during the day. CONCLUSIONS: toilet training began early in a significant number of children and an insignificant proportion of mothers received guidance from pediatricians on this. Information regarding the ideal time and adequate methods for introducing sphincter control should be offered to mothers during puerperium as part of basic health care.

Foram examinados 473 artigos, sendo selecionados 85. 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.

OBJECTIVE: 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 published guidelines on toilet training. CONCLUSIONS: Toilet training is occurring later in the majority of countries. The training methods that exist are the same from decades ago and are rarely used by mothers and valued little by pediatricians; incorrect training can be a causative factor for bladder and bowel disorders, which in turn cause problems for children and their families.
