O questionário é ilustrado com 21 alimentos e foi delineado para uso em nível de grupo. Participaram 131 escolares de oito a dez anos de idade de uma escola pública de período integral da cidade de Balneário Camboriú, Santa Catarina, em 2005. A reprodutibilidade foi avaliada em duas aplicações do questionário no mesmo dia. A validade foi obtida pela comparação entre os itens alimentares selecionados no questionário e a observação direta de três refeições escolares do dia anterior. O questionário apresentou alta sensibilidade, com valores variando entre 73,4% (feijão) e 95,5% (arroz), e alta especificidade, variando entre 87,3% (frutas) e 98,8% (feijão). Conclui-se que o questionário pode gerar dados reprodutíveis e válidos para avaliar o consumo alimentar de escolares no dia anterior.

This was a population-based cross-sectional study in the city of Chapecó, Santa Catarina State, Brazil, analyzing the relationship between oral health conditions and quality of life in 35-44-year-old adults (n = 622). A further objective was to observe the influence of habits, dental visits, self-evaluation of health status, and socio-demographic characteristics in this process. The sample was selected using a multiplestage approach. Trained professionals collected the data. A multiple non-conditional, hierarchical logistic regression model was used to analyze the determinants of low (Oral Impact on Daily Performance -OIDP ≤ 3) and high (OIDP ≥ 10) interference of oral health in daily routine. The response rate was 81%. Oral health status was found to interfere in the daily routine of 20.7% of participants and was more severe for 11.4%. Household crowding, low-income neighborhoods, female gender, and orofacial pain in the previous six months were associated with higher interference in quality of life. The use of subjective indicators in public health services planning and definition of priority groups for delivery of oral health services is highly recommended.

The strengths and limitations of the Previous Day Food Questionnaire (PDFQ) are also presented. Frequencies of intake were defined as how many times per day the food group was reported on the PDFQ. The percentages of schoolchildren who met the minimum recommendations and who ate foods that were not recommended in the guidelines were compared for boys versus girls, private versus public school and by family income level. Although most of the children complied with the guidelines regarding consumption of meat/fish, dry beans, sweets, and eating three meals and two snacks, only 6.5% of the children met the recommendations for cereals, and 15% for fruit and vegetables. The PDFQ was confirmed as a practical and cost-effective method for the evaluation of compliance with health promotion targets.

The aim of the present study was to describe WC percentiles in 7-to 10-year-old Brazilian children and to compare frequencies of obesity and overweight as defined by BMI and frequencies of excess and at risk of abdominal adiposity as defined by WC to the corresponding age and sex data from British references. A representative sample of 2919 schoolchildren of the city of Florianopolis (southern Brazil) was examined. Smoothed WC percentiles were derived using the least mean square method. Frequencies of overweight and obesity and of excess and at risk of abdominal adiposity were assessed using the 91st and 98th centiles of the British references as cut-off points. WC increased with age in both boys and girls, with higher values for boys at every age and percentile level. Nutritional status categories of children assessed by the 91st and 98th British BMI and WC centiles showed moderate agreement (weighted k ¼ 0·58). Overweight was more frequent in Brazilian than British children: 15·1 % of girls and 20·1 % of boys were above the 91st percentile of the 1990 BMI for age British references. About one-quarter (22·0 % of girls and 26·9 % of boys) exceeded the 91st percentile of WC British references. The present data could be used to compare WC in children in other populations and may serve as a baseline for future studies of temporal trends in WC in Brazil.
