Abstract: physical activity and diet are related to several health outcomes. the aim of this study was to analyze physical activity (pa) and diet patterns among brazilian schoolchildren attending private or public schools. a cross-sectional, school-based study of elementary schoolchildren aged 7-10 years old (n = 2,936) was carried out in florianopolis (southern brazil). self-reported food consumption and pa patterns were assessed by means of a questionnaire. a higher percentage of girls than boys met the recommendations for consumption of fruits and vegetables and limited their consumption of sweets and soft drinks. boys reported higher pa levels than girls (p < 0.001). children attending private schools were more likely to be in the highest tertile of pa (odds ratio = 1.53, 1.14-2.05) and 80% less likely to be active in commuting to school compared to public school students. private schoolchildren were more likely to meet recommendations for fruits and vegetables, limit sweet consumption, report adequate meal frequency and no consumption of fast food or soft drinks. in summary, girls and private schoolchildren reported better eating patterns, while boys and private schoolchildren reported higher pa levels. such results highlight the public school setting as a target for health promotion initiatives, along with other strategies, in developing countries.

Abstract: the aim of this study was to determine the reliability of the physical activity and food consumption (pafc) questionnaire in schoolchildren from a private school in natal-rn, brazil. a total of 101 children, 57 boys and 44 girls (mean age: 9.4 years, sd: 1.03, range: 7.3 to 11.6) in the second to fourth grade of elementary school were recruited. an expanded version of the pafc questionnaire was applied at the school by a single researcher, with an average of 15 days between test and retest. the coefficient of relative agreement, intraclass correlation coefficient, spearman's correlation coefficient, kappa index of agreement, pabak, and wilcoxon signed-rank test were used to determine reliability. in general, relatively consistent measures between the two questionnaire sessions were found for items related to attitude towards exercise (0.41), means of transportation used to travel to and from school (0.79), and the remaining 11 physical activities (0.69). an intraclass correlation of 0.87 as obtained for the overall physical activity index. twenty-seven of the 42 items presented moderate to good agreement (mean kappa index: 0.51). the pafc questionnaire showed moderate to good reliability for most of its items and seems to be a suitable instrument for the evaluation of physical activity and food intake behavior in schoolchildren. moreover, the questionnaire might be used as an alternative for the classification of more and less active individuals as well as for the identification of healthy and inadequate dietary patterns.

Abstract: OBJETIVO: Estimar a prevalência e os padr es dos fatores de risco para doen as cr nicas n o transmissíveis segundo o nível socioecon mico e a idade dos adolescentes. MéTODOS: Estudo transversal de base escolar envolvendo 1.675 adolescentes (53% do sexo feminino), com idades de 11 a 17 anos, de escolas públicas e privadas. O consumo de tabaco e álcool, o alto consumo de gordura na dieta e o baixo nível de atividade física constituíram as variáveis comportamentais. Circunferência da cintura e press o arterial elevada, assim como e baixa aptid o cardiorrespiratória compuseram as variáveis biológicas. Regress o logística multinomial foi realizada para identificar variáveis associadas à simultaneidade dos fatores de risco para doen as cr nicas n o transmissíveis. RESULTADOS: Dos adolescentes, 62 e 31% apresentaram baixa aptid o cardiorrespiratória e elevado consumo de gordura, respectivamente. Dois em cada dez adolescentes tinha dois ou mais comportamentos de risco, e um ter o deles tinham pelo menos dois fatores de risco biológicos para doen as cr nicas n o transmissíveis. No total, 62% dos adolescentes tinham pelo menos dois fatores de risco para doen as cr nicas n o transmissíveis, com maior frequência nos estudantes mais velhos. Na análise simultanea de todas as variáveis, observou-se que o aumento da idade esteve associado ao acúmulo de dois ou mais fatores de risco (sexo masculino com OR 2,10, e feminino com OR 5,74). CONCLUS ES: Seis em cada dez adolescentes tinham pelo menos dois fatores de risco, enquanto a propor o do agrupamento desses fatores aumentou com a idade. Portanto, quanto mais precoce forem as interven es, provavelmente menos adolescentes estar o acometidos por agravos à saúde em idades mais avan adas. OBJETIVO: Estimar la prevalencia y los estándares de los factores de riesgo para enfermedades crónicas no transmisibles, según el nivel socioeconómico y la edad de los adolescentes de Caxias do Sul, en Rio Grande do Sul, Brasil. MéTODOS: Estudio transversal de base escolar, involucrando a 1.675 estudiantes (53,2% del sexo femenino), con edades entre 11 y 17 a os, de escuelas públicas y privadas. El consumo de tabaco y alcohol, el alto consumo de grasa en la dieta y el bajo nivel de actividad física constituyeron las variables comportamentales. Circunferencia de la cintura y presión arterial elevada y baja aptitud cardiorrespiratoria compusieron las variables biológicas. Se realizó regresión logística multinominal para identificar variables asociadas a la simultaneidad de los factores de riesgo para enfermedades crónicas no transmisibles.

Abstract: background: cardiovascular diseases are the major cause of death in the population, and metabolic syndrome (ms) is a clinical condition significantly associated with the increase in morbidity and mortality. objective: to describe the pattern of combination of the risk factors related to the diagnosis of ms in the military personnel of the brazilian navy and to identify variables associated with the presence of ms in that population. methods: cross-sectional study involving 1,383 men (18-62 years) assigned to military organizations in the city of natal, state of rio grande do norte. the criterion proposed by the international diabetes association was used for the diagnosis of ms. the ratio between observed and expected prevalence and the respective confidence intervals were used to identify the combinations of risk factors that exceeded that expected for the population. logistic regression was used to identify variables associated with ms. results: the prevalence of ms was 17.6%. approximately one third of the military personnel studied had two or more risk factors for ms. all specific combinations of risk factors for ms that exceeded the expected prevalence had abdominal obesity as one of its components. in the adjusted analyses, age, smoking and physical activity level remained associated with ms. conclusion: our findings reinforce the constant presence of abdominal obesity in the phenotype of ms. in addition, our data also support the idea that age, smoking and low level of physical activity are independent variables for the occurrence of ms.

Abstract: Objective: This study aimed to investigate the circadian typology of medical students at public universities from one of the northeastern states in Brazil, active in the morning and afternoon shifts, checking the compatibility between their study time, productivity, income and chronotype. Methods: To obtain the results, the assessment of the chronotype in 342 medical students of both sexes was considered. Each participant was submitted to the questionnaire developed by Horne and Ostberg, adapted by Cardinali, Colomberk and Rey. It’s composed of 9 questions, providing the general ranking of each individual. Based upon scored, the chronotypes were classified. Results: The sample was composed of 49.12% (168) male and 50.87% (174) female subjects, a similar gender distribution of enrolled students during data collection time. By applying the questionnaire, the prevalent rating among the medical students as moderately morning (29.82%) and intermediate (43.85%) has been relevant. The academic performance assessment in two morning-intermediate groups (8.16) had no significant distance from others considered afternoon active (8.20). Conclusion: The health sciences student, especially Medicine, faces constant adaptation of scheduling, in the attempt of fulfilling the requirements throughout the course, causing chronogram desynchronization effects and forced readaptation to each different school semester.
