Previous issue date: 2016-06-10 === Intestinal constipation is the most common intestinal motility disorder in the world. The objective of the current study was to evaluate the prevalence, associated factors and reliability of data on intestinal constipation in children at six months of age, according to the maternal impression; Having as main products two articles: "Intestinal constipation in children at six months of age, according to maternal report of arrested gut" and "Prevalence and factors associated with intestinal constipation at six months of age". This was a cross-sectional analysis of a cohort of live births, who followed mother-infant pairs through monthly home visits in the first six months of life. The power of the current study was 91.36%. The dependent variable was constipation of the child reported according to the maternal impression. The other variables were related to the maternal, infant and eating habits of the child. The database was entered in the statistical software SPSS (Statistical Package for the Social Sciences) version 10.0, later validated in the statistical software EPIDATA and analyzed with the help of the program STATA, version 12.0. Pearson's chi-square test was used, and their respective 95% confidence intervals (95% CI). The multivariate analysis was performed using Poisson regression in a hierarchical analysis model, adopting the significance level of 20% (p <0.20), and maintaining in the final model the variables that showed association with the dependent variable At the level of statistical significance p <0.05. To evaluate the concordance between the maternal impression and the characteristics of the intestinal habit, the kappa index was used. Among the 1,134 infants studied, 12.3% of the population had intestinal constipation at six months of age. In the bivariate analyzes, there was statistical significance for the liquidized food variable (p = 0.00) and after multivariate analysis it was verified that these foods were a risk factor for intestinal constipation RP = 1.50 (95% CI: 1.07 -2.11, p = 0.00). According to the kappa index, the agreement between the maternal impression that the child was evacuating every day was considered moderate (kappa = 0.55); (Kappa = 0, 18) and the stool appearance was substantial (kappa = 0.67). This study found prevalence of functional constipation in children at six months of age, similar to other studies developed in Brazil and the world, based on the maternal report. It is noteworthy that children who consumed liquefied foods were more likely to develop intestinal constipation. Regarding the reliability of the maternal impression, it was concluded that the characteristics of greater agreement corresponded to the appearance of hardened stools and to the daily frequency of bowel movements, emphasizing that the maternal report on the attached intestine can be a good indicator to recognize cases of intestinal constipation Six months of age. This project was approved by the Research Ethics Committee - CEP / UEFS - Protocol 077/2006 and the Higher Council for Teaching, Research and Extension - CONSEPE / UEFS - Protocol 154/2007, CAAE - 49106715.8.0000.0053. === A constipa??o intestinal ? o dist?rbio de motilidade intestinal mais frequente em todo o mundo. O objetivo do atual estudo foi avaliar a preval?ncia, os fatores associados e a confiabilidade dos dados sobre a constipa??o intestinal de crian?as aos seis meses de idade, conforme a impress?o materna; tendo como principais produtos dois artigos: ?Constipa??o intestinal em crian?as aos seis meses de idade, segundo relato materno de intestino preso? e ?Preval?ncia e fatores associados ? constipa??o intestinal aos seis meses de idade?. Tratou-se de uma an?lise transversal de uma coorte de nascidos vivos, que seguiu duplas m?e-filho mediante visitas domiciliares mensais, nos primeiros seis meses de vida. O poder do atual estudo foi de 91,36%. A vari?vel dependente foi constipa??o intestinal da crian?a relatada segundo a impress?o materna. As demais vari?veis foram referentes ?s caracter?sticas maternas, infantis e aos h?bitos alimentares da crian?a. O banco de dados foi digitado no software estat?stico SPSS (Statistical Package for the Social Sciences) vers?o 10.0, validados posteriormente no software estat?stico EPIDATA e analisados com ajuda do programa STATA, vers?o 12.0. Foi utilizado teste de qui-quadrado de Pearson, e seus respectivos intervalos de 95% de confian?a (IC95%). A an?lise multivariada foi realizada por meio de regress?o de Poisson em um modelo de an?lise hier?rquica, adotando-se o n?vel de signific?ncia de 20% (p < 0,20), e mantidas no modelo final as vari?veis que apresentaram associa??o com a vari?vel dependente em n?vel de signific?ncia estat?stica p<0,05. Para avaliar a concord?ncia entre a impress?o materna e as caracter?sticas do h?bito intestinal foi utilizado o ?ndice kappa. Dentre os 1.134 lactentes estudados, 12,3% da popula??o apresentou constipa??o intestinal aos seis meses de idade. Nas an?lises bivariadas, houve signific?ncia estat?stica para a vari?vel dos alimentos liquidificados (p=0,00) e ap?s an?lise multivariada verificou-se que esses alimentos foram fator de risco para a constipa??o intestinal RP=1,50 (IC95%:1,07?2,11; p=0,00). Segundo o ?ndice kappa, a concord?ncia entre a impress?o materna de que a crian?a evacuava todos os dias foi considerada moderada (kappa=0,55); quanto ? frequ?ncia de evacua??es semanais, a concord?ncia foi ligeira (kappa=0,18) e quanto ao aspecto das fezes, foi substancial (kappa=0,67). Este trabalho encontrou preval?ncia de constipa??o funcional de crian?as aos seis meses de idade, similar a outros estudos desenvolvidos no Brasil e no mundo, com base no relato materno. Destaca-se que as crian?as que consumiam alimentos liquidificados tinham mais chances de desenvolver constipa??o intestinal. Quanto ? confiabilidade da impress?o materna, conclui-se que as caracter?sticas de maior concord?ncia foram correspondentes ao aspecto de fezes endurecidas e ? frequ?ncia di?ria de evacua??es, salientando que o relato materno sobre o intestino preso pode ser um bom indicador para reconhecer casos de constipa??o intestinal aos seis meses de idade. Esse projeto foi aprovado pelo Comit? de ?tica em Pesquisa - CEP/UEFS - Protocolo 077/2006 e Conselho Superior de Ensino, Pesquisa e Extens?o - CONSEPE/UEFS - Protocolo 154/2007, CAAE - 49106715.8.0000.0053.
