Objective: The aim of the current study was to identify and describe the meal and snack patterns (breakfast, mid-morning snack, lunch, mid-afternoon snack, dinner and evening snack) of public schoolchildren. Design: Cross-sectional study. Information on the previous day’s food intake was obtained through the Web-CAAFE (Food Intake and Physical Activity of Schoolchildren), an interactive questionnaire, which divides daily food consumption into three meals (breakfast, lunch and dinner) and three snacks (mid-morning, mid-afternoon and evening). Each meal contains thirty-one food items and the schoolchildren clicked on the food items consumed in each meal. Factor analysis was used to identify meal and snack patterns. The descriptions of the dietary patterns (DP) were based on food items with factor loads ≥ 0·30 that were considered representative of each DP. Setting: Schoolchildren, Florianopolis, Brazil. Participants: Children (n 1074) aged 7–13 years. Results: Lunch was the most consumed meal (96·0 %), followed by dinner (86·4 %), breakfast (85·3 %) and mid-afternoon snack (81·7 %). Four DP were identified for breakfast, mid-morning snack, lunch, dinner and evening snack, and three for mid-afternoon snack. Breakfast, lunch and dinner patterns included traditional Brazilian foods. DP consisting of fast foods and sugary beverages were also observed, mainly for the evening snack. Conclusions: The results of the current study provide important information regarding the meal and snack patterns of schoolchildren to guide the development of nutrition interventions in public health.

Objective To identify trends in food consumption among schoolchildren (2nd-5th grades) from public schools in the city of Florianópolis, Brazil, in a period of three years. Methods Three cross-sectional surveys were carried out in 2013 (n=1,942), 2014 (n=1,989) and 2015 (n=2,418). Dietary intake data were obtained using the Web-Based Food Intake and Physical Activity of Schoolchildren questionnaire. Food items were aggregated to eight food groups. Kruskal-Wallis heterogeneity and trend tests were used to analyze the differences and trends among the mean intake frequency of food groups. Results There were trends to decrease the mean intake frequency of sweets in the total sample (2013: 0.72±0.91; 2014: 0.68±0.87; 2015: 0.67±0.89, p=0.03) which was determined by children between 7-9 years old (2013: 0.69±0.88; 2014: 0.64±0.85; 2015: 0.62±0.87, p=0.02), and boys (2013: 0.75±0.90; 2014: 0.70±0.86; 2015: 0.68±0.88, p=0.03). Younger children also tended to increase the mean intake frequency of fruits and vegetables (2013: 1.03±1.35; 2014: 1.16±1.45; 2015: 1.17±1.41, p=0.03) and those aged ten-12 years decreased their intake of dairy products (2013: 1.32±1.25; 2014: 1.23±1.18; 2015: 1.20±1.20, p=0.05). Conclusion The results suggest positive trends for younger children, with an increased consumption of fruits and vegetables in both sexes and decreased consumption of sweets for boys. Older children reduced their consumption of dairy products over the three-year period of this study.

RESUMO: Introdução: O questionário de Consumo Alimentar e Atividade Física de Escolares (Web-CAAFE) foi desenvolvido para o monitoramento da dieta e atividade física de escolares brasileiros. Este estudo buscou avaliar o efeito do dia da semana e do número de aplicações na reprodutibilidade do Web-CAAFE. Metodologia: Escolares do 2º ao 5º ano (n = 197) de Florianópolis preencheram o Web-CAAFE por duas vezes no mesmo dia, dos quais 113 o fizeram em três dias não consecutivos. Avaliou-se a reprodutibilidade por meio da correlação intraclasse (CCI) e da regressão logística, para avaliação dos fatores associados à pior reprodutibilidade. Resultados: Observaram-se piores resultados de reprodutibilidade para o preenchimento do consumo nos finais de semana em relação àqueles que responderam em dias da semana (odds ratio - OR = 2,93; p = 0,045) e melhores resultados em meninas em relação aos meninos (OR = 0,29; p < 0,001). O preenchimento do consumo realizado nos segundo e terceiro dias apresentou melhor reprodutibilidade que o realizado no primeiro. Esses resultados são relevantes para o planejamento de futuros estudos que utilizem instrumentos de consumo alimentar em crianças, em especial sobre avaliação de sua validade e reprodutibilidade. Conclusões: Os resultados sugerem que pelo menos dois dias de aplicação do Web-CAAFE fornecem resultados aceitáveis de reprodutibilidade, e que o preenchimento referente ao fim de semana pode reduzi-la.

This study aims to describe the time trend of age at menarche in Brazilian schoolgirls evaluated in 2007, 2012/2013 and 2018/2019, and to assess its association with having overweight, including obesity and socio-economic conditions. Three cross-sectional studies were carried out in 2007, 2012/2013 and 2018/2019 in schoolchildren enrolled between the second and ninth years of elementary school and comprising 838, 688 and 326 schoolgirls, respectively. Body mass index Z scores were calculated and categorised as either without overweight or with overweight (including obesity). The type of school (a proxy of socio-economic condition) was categorised as either public or private. Menarche data were collected using the status quo and recall methods. The mean age at menarche was estimated by survival analysis. Differences in age at menarche according to the year of survey, weight status and type of school were verified by the Log-Rank test and Cox's univariate and multiple regression. There was an increase in the prevalence of overweight in girls throughout the surveys, with 21.4% in 2007, 27.2% in 2012 and 28.5% in 2018 (p = 0.007) having overweight. There was a decrease in the mean age at menarche between 2007 and 2018/2019 (12.3 vs. 11.9 years, respectively). The mean age at menarche in girls with overweight was lower in the three time periods when compared to girls without overweight (11.9, 11.8 and 11.5 vs. 12.4, 12.4 and 12.1, respectively).Girls with overweight were more likely to have had earlier age at menarche than girls without overweight (Hazard Ratio 1.57; 95% CI 1.36; 1.80). There were no differences in the age at menarche according to the type of school. The increase in the prevalence of girls with overweight (including obesity) may be associated with the age at menarche. Girls with overweight had a higher risk of earlier age at menarche than girls without overweight.

The purpose of this systematic review was to summarize the evidence from observational studies regarding the association between lifestyle patterns and overweight and obesity in adolescents. To our knowledge, no review study has analyzed this association in this age group. A systematic search was conducted in LILACS, Scopus, PubMed Central, and Web of Science databases, with no language or time restrictions. Studies that included adolescents (10–19 years old) were selected using data-driven methods that combined the diet domain with at least one of the following behavioral domains: physical activity, sedentary behavior, and sleep. Twenty-one articles met all eligibility criteria. Of these, 12 studies were used for synthesizing the results. Studies differed in many aspects, such as sample size, behavioral assessment tools, and lifestyle pattern and weight status indicators. Overall, cross-sectional studies found no association between lifestyle patterns and overweight and obesity, even when the data were stratified by sex. However, when analyzing the results stratified by risk of bias, a positive association between predominantly unhealthy and mixed lifestyle patterns with overweight/obesity was identified in cross-sectional studies with moderate risk of bias. A prospective study revealed an increase in body mass index over time associated with mixed and predominantly unhealthy lifestyle patterns. Current findings regarding the association between lifestyle patterns and overweight and obesity in adolescents are inconsistent. More studies are needed to clarify possible associations.

ResumoO estado nutricional e o consumo alimentar de escolares da rede pública municipal de Florianópolis, SC, foi avaliado com o objetivo de elaborar um plano de ação organizado na forma de material didático para a educação nutricional no ambiente escolar. O estado nutricional foi avaliado pelo índice de massa corporal e o consumo alimentar, através do Questionário do Consumo Alimentar e Atividade Física de Escolares (webCAAFE). Entre março e novembro de 2014, 640 escolares de 7 a 10 anos de nove escolas da rede pública foram avaliados, sendo observados 20% de sobrepeso, 13% de obesidade e elevado consumo de alimentos não saudáveis. O material didático organizado em uma cartilha abordou oito temáticas, estruturada com texto de apoio ao professor, exemplo de aula dialogada, texto de apoio ao aluno e atividades lúdico-educativas. Espera-se que a cartilha contribua para o incremento das ações de educação nutricional e auxilie na promoção de hábitos alimentares saudáveis desde a infância. Palavras-chave: Consumo Alimentar.

NUTRITIONAL DIAGNOSIS AND DEVELOPMENT OF TEACHING MATERIALS FOR NUTRITION EDUCATION OF SCHOOLCHILDREN AbstractThe nutritional status and food intake of school-aged children from the municipal public school network of the city of Florianopolis, SC, were evaluated in order to draw up a plan of action organized in the form of educational materials for nutrition education at school. The nutritional status was assessed through the Body Mass Index (BMI) and food consumption through the online Questionnaire on Food Consumption and Physical Activity in School-Aged Children (webCAAFE). Between, march to november of 2014, 640 school-going children aged 7 to 10 years from nine municipal public schools were evaluated. A prevalence of 20% of overweight and 13% of obesity was observed, in addition to a high consumption of foods of low nutritional value. The teaching material was organized in a booklet covering eight different subjects, structured with supporting text for the teacher, an example of a collaborative class, supporting text for the student and playful educational activities. It is hoped that the booklet will contribute to the improvement of nutritional education actions and assist in the promotion of healthy eating habits since childhood. Keywords: Food Intake.
