Hypoacousis prevalence in Kaiowá and Guarani indigenous children

OBJETIVOS: identificar a prevalência de hipoacusia em crianças indígenas Kaiowá e Guarani. MÉTODOS: estudo transversal, com uma amostra de 126 crianças indígenas de zero a 59 meses da Terra Indígena de Caarapó, em Mato Grosso do Sul, Brasil. As crianças foram submetidas ao exame das emissões otoacústicas evocadas transitórias, que serviu como triagem auditiva. O reteste foi realizado nas crianças que apresentaram resultado alterado na triagem auditiva. Os casos que, no reteste, permaneceram alterados foram encaminhados para o exame da imitanciometria. RESULTADOS: na triagem auditiva, foram identificadas 25 (23,6%) crianças com resultado alterado; dessas, 17 apresentaram resultado normal no reteste e 6 permaneceram com resultado alterado, sendo encaminhadas para imitanciometria. A prevalência de hipoacusia identificada ao final do estudo foi de 5,6%, sendo 3 (2,8%) do tipo condutiva e 3 (2,8%) do tipo neurossensorial. Estas últimas foram encaminhadas à avaliação otorrinolaringológica complementar para confirmação diagnóstica. As alterações auditivas identificadas neste estudo não apresentaram diferenças significantes quanto ao sexo e grupo etário. CONCLUSÕES: a prevalência de alteração auditiva encontrada nesta população alerta para a necessidade de implantação de programas de saúde auditiva e sua articulação com outras ações desenvolvidas na atenção à saúde infantil dos Kaiowá e Guarani.

Assessment of the diet of 0- to 6-year-old children in municipal schools in a Brazilian city

Diet control is one of the important factors in the prevention of dental caries because food functions as substratum for fermentation and, consequently, for the formation of the organic acids that demineralize the tooth surface. This study aims to descriptively assess school diet and the associated caries-preventive methods applied to children in all municipal nursery schools of a Brazilian city (Aragatuba/SP). For this, a questionnaire with open and closed questions was used. The results showed that all schools serve school meal, which is composed mainly of sugar, carbohydrates, and proteins. The students enjoy the meal very much because for most of them, the meal served at school is the only source of food. It was observed that 90% of the schools offer other kinds of food besides the main school meal. The snacks served such as cakes, white hominy, and milk fudge are composed of sweet and highly cariogenic foods. It was also verified that in 13.30% of the schools, the daily supervised dental hygiene, an important procedure that should not be neglected, is not carried out. This procedure introduces the children to healthy habits that are added to those acquired in the family environment. It was concluded that the school diet is potentially cariogenic and, in association with the lack of daily dental hygiene, this potential may become even higher.

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.

Evaluation of children's behavior aged 0-3 years during dental care: A longitudinal analysis

Child temperament has been studied in various researches and may be useful to predict how a child responds to dental treatment, especially very young children. The purpose of the present longitudinal study was to evaluate the behavioral manifestation of children aged 0 to 3 years, considering different types of dental situation. A total of 169 children were selected and the following data were collected: the age of the child, gender, age of the mother, number of dental visits and their respective dates, stimuli offered to the child, and behavioral response to these stimuli. The children and their respective behaviors were divided into five groups according to the dental situation offered: control, missed visits, fluoride varnish, restoration, and dental trauma. The data were submitted to descriptive and inferential analysis using the chi-square test, with the level of significance set at 5%. Analysis of the different situation offered to infants during routine dental care revealed a predominance of collaborating and partially collaborating behavior, and age at the time of dental care influenced the behavior of the infants, irrespective of the stimulus group. The different types of dental situation provoked changes in the behavioral response of the children of certain age groups, especially in the dental trauma group.
