Maternal perception of the childs nutritional status from the perspective of adjusted residual analysis / Percepção materna do estado nutricional do filho sob a óptica da análise dos resíduos ajustados

BACKGROUNG: The maternal perception of the nutritional status of their children has several important social factors in its composition and it can be important in determine quality of children's foodOBJECTIVE: To assess social factors influencing maternal perception of her children´s nutritional statusMETHODS: Cross sectional study with school children from 6 to 10 years from a public school in São Paulo, Brazil. The data was obtained through a structured questionnaire applied to mothers and through children's body mass index. Associations between variables were analyzed by the Qui-square test and by the adjusted residues analysis, with 5% of significance. The agreement between maternal perception and nutritional status was assessed through the Kappa testRESULTS: We found incorrect perception in 45.8% of cases, from which 98.2% were underestimation, with 80% of underestimation for overweight children. We found poor and slight agreement for all cases. Adjusted residuals pointed eutrophic underestimation; better maternal perception for the obese; better perception for mothers that attained middle and high school levels; underestimation for eutrophic boys and correct perception for eutrophic girls. Single mothers and those who do not work outside tended to underestimate their eutrophic childrenCONCLUSION: We found poor agreement for almost all cases, with exception to mothers of girls and those that do not work outside. A correct perception was related positively with lower education levels, being worse for mothers without a partner and for those who do not work outside. Mothers of girls, compared to mothers of boys, had a more accurate perception

INTRODUÇÃO: A percepção materna do estado nutricional de seus filhos apresenta diversos fatores sociais importantes em sua composição e ela pode ser um importante na determinação da qualidade de alimentação das criançasOBJETIVO: Avaliar os fatores sociais que influenciam a percepção materna sobre o estado nutricional de seus filhosMÉTODO: Estudo transversal com escolares de 6 a 10 anos de uma escola pública de São Paulo, Brasil. Os dados foram obtidos por meio de um questionário estruturado aplicado às mães e a partir de antropometria das crianças. As associações entre as variáveis foram analisadas pelo teste do Qui-quadrado e pela análise dos resíduos ajustados, com 5% de significância. A concordância entre a percepção materna e o estado nutricional foi avaliada por meio do teste KappaRESULTADOS: Encontramos percepção incorreta em 45,8% dos casos, dos quais 98,2% foram de subestimação, com 80% de subestimação para crianças com sobrepeso. Encontramos concordância pobre e leve para todos os casos. Os resíduos ajustados apontaram para subestimação eutrófica; melhor percepção materna para o obeso; melhor percepção para mães que atingiram o ensino fundamental e médio; subestimação para meninos eutróficos e percepção correta para meninas eutróficas. As mães solteiras e as que não trabalham fora tendem a subestimar seus filhos eutróficosCONCLUSÃO: Encontramos baixa concordância para quase todos os casos, com exceção das mães de meninas e das que não trabalham fora. A percepção correta relacionou-se positivamente com a menor escolaridade, sendo pior para as mães sem companheiro e que não trabalham fora. As mães de meninas, em comparação com as mães de meninos, tiveram uma percepção mais precisa

Maternal Chlamydia trachomatis Infections and Preterm Births in a University Hospital in Vitoria, Brazil.

BACKGROUND: Preterm birth (PTB) is a major determinant of neonatal morbimortality with adverse consequences for health. The causes are multifactorial, with intrauterine infection probably explaining most of these outcomes. It is believed that infection with Chlamydia trachomatis (CT) is also involved in PTB and premature rupture of membranes. OBJECTIVES: To evaluate the prevalence of and associated factors for CT among cases of PTB attended at a University Hospital in Vitoria, Brazil. METHODS: A cross-sectional study performed among parturient who had preterm birth from June 2012 to August 2013 in Vitoria, Brazil. Participants answered a questionnaire including demographic, behavioral, and clinical data. A sample of urine was collected and screened for CT using polymerase chain reaction. Chi-square tests were used for proportion differences and Student's-t tests and variance analysis were used for testing differences between mean values. Odds ratio was used as a measure of association with a 95% confidence interval. RESULTS: The prevalence of PTB during the period of the study was 26% and the prevalence of CT among them was 13.9%. A total of 31.6% pregnant women were younger than 25 years old and women infected by CT were even younger than women not infected by CT (p = 0.022). Most of them (76.2%) were married or had a living partner, and CT infection was more frequent among the single ones (p = 0.018); 16.7% of women reported their first sexual intercourse under 14 years old. The causes of prematurity were maternal-fetal in 40.9%; rupture of the membranes in 29.7% and premature labor in 29.4%. In multivariate analysis, being married was a protective factor for infection [OR = 0.48 (95%CI:0.24-0.97)]. None of the other characteristics were associated with CT infection. CONCLUSIONS: This study shows a high prevalence of CT infection among parturient who have preterm birth. This high prevalence highlight the need for defining screening strategies focused on young pregnant women in Brazil.
