The aim of this study is to evaluate the influence of dietary patterns on the occurrence of dental caries. Using a population-based, cross-sectional study design, we assessed a sample of 1.439 children aged 6-13 years who were enrolled in public schools in the municipality of São Francisco do Conde, Bahia state, Brazil. Oral examinations for dental caries were performed by two dental surgeons (Kappa = 0.72) in the school environment under natural light with the aid of a wooden spatula and gauze. Dietary intake was assessed using the qualitative-quantitative food frequency questionnaire. A questionnaire on the demographic and socioeconomic conditions was applied to the families. The Poisson multivariate analysis was performed for statistical purposes. Considering both dentitions, the prevalence of caries was 82.14% and 37.3% in the permanent and deciduous dentitions, respectively. The identified dietary patterns were classified into “standard obesogenic" and "prudent." The results showed statistically significant association between the obesogenic dietary pattern and dental caries; the proportion of students with dental caries was 1.4 times higher among those who most frequently consumed foods that constitute a standard obesogenic diet (PR = 1.40, 95% CI: 1.04-1.96) compared to those who less frequently consumed these types of foods. A positive association between the obesogenic dietary pattern and dental caries was found in the students investigated. Therefore, the promotion of healthy eating habits and nutritional habits should be encouraged to prevent dental caries in children and adolescents. ResumoO objetivo deste estudo é avaliar a influência de padrões alimentares sobre a ocorrência de cárie dentária. Realizou-se um estudo transversal de base populacional, com uma amostra de 1.439 crianças de 6 a 13 anos, matriculadas em escolas públicas da cidade de São Francisco do Conde, no Estado da Bahia. Os exames de cárie dentária foram realizados por dois cirurgiões-dentistas (Kappa=0,72) no ambiente escolar, sob luz natural, com o auxílio de uma espátula de madeira e gaze. A ingestão alimentar foi avaliada por meio do questionário qualitativo-quantitativo de frequência alimentar. Um questionário sobre as condições demográficas e socioeconômicas foi aplicado nas famílias. A análise multivariada de Poisson foi realizada para fins estatísticos. Considerando ambas as dentições, as prevalências de cárie foram 82,14 e 37,3% nas dentições permanentes e decíduas, respectivamente. Os padrões alimentares identificados foram classificados em "padrão obesogênico", e os resultados mostraram uma associação estatisticamente significativa entre o padrão alimentar obesogênico e a cárie dentária "prudente". A proporção de alunos com cárie foi 1,4 vez maior entre aqueles que consomem frequentemente alimentos constituídos de uma dieta obesogênica padrão (RP=1,40 e IC95%=1,04-1,96) em comparação com aqueles que consomem, com menor frequência, esses tipos de alimentos.Uma associação positiva entre o padrão alimentar obesogênico e a cárie dentária foi encontrada nos estudantes Portanto, a promoção de hábitos alimentares saudáveis e de hábitos nutricionais devem ser incentivados como forma de prevenção da cárie dentária em crianças e em adolescentes.

No. of bitstreams: 1 Mauricio Barreto et al. 2013.pdf: 394363 bytes, checksum: 6ce57c2cdfa75eaea3c6fa87eea3ef06 (MD5) Previous issue date: 2013 Objective: To evaluate the association between food and nutrition insecurity and asthma in children from Latin America. Design: Cross-sectional study. Setting: São Francisco do Conde, Bahia, north-eastern Brazil. Subjects: The study included 1307 children aged 6–12 years from public elementary schools. Asthma symptoms were collected using a questionnaire that was translated and adapted from the International Study of Asthma and Allergies in Childhood,phase III. The diagnosis of asthma was determined based on reports of wheezing in the previous 12 months. The Brazilian Food Insecurity Scale was used to identify food insecurity. We also obtained demographic, socio-economic and anthropometric information for each participant. We used multivariate logistic regression analyses to assess the associations of interest. Results: Of the children surveyed, 10?4% had a history of wheezing and 64?5% had some degree of food and nutrition insecurity. We found a positive dose–response relationship and statistically significant associations of asthma with moderate (OR51?71, 95% CI 1?01, 2?89) and severe (OR52?51, 95% CI 1?28, 4?93) food and nutrition insecurity. Conclusions: The results show that moderate and severe food and nutrition insecurity are markers of vulnerability to wheezing. It is important to note that the results of studies in this field have potential implications for social policies that promote food security. Further studies to identify the mechanisms involved in the relationship between food and nutrition insecurity and asthma are needed. Wallingford
