Physical Activity, Blood Glucose and C-Peptide in Healthy School-Children, a Longitudinal Study

Aim To further elucidate the relationship between physical activity and several risk factors for development of diabetes (glucose, C-peptide and obesity) over time. Methods A prospective longitudinal study where physical activity was measured on 199 children from Kalmar and Linköping at age 8, and the same 107 children from Linköping again at age 12. Anthropometric data was collected and blood was analyzed for C-peptide and f-glucose. The children in the study were representative for the general Swedish child population, and on an average lean. Results High physical activity was related to lower C-peptide at age 8 and 12. This correlation was especially pronounced in boys, who also were more physically active than girls at both time points. The association seen at 8 years of age was similar at age 12 in most children. Children with higher BMI Z-Score had a higher fasting C-peptide (age 12) but linear regression showed that children with more steps per day were less likely to have a higher fasting C-peptide irrespective of BMI. Longitudinal follow-up showed that a decrease in physical activity increased insulin resistance and β-cell load. Conclusions Already in young children, physical activity improves insulin sensitivity and decreases the need of C-peptide over time. This seems to become even more pronounced with increasing age when children are followed longitudinally. Low physical activity increases the load on insulin producing β-cells, might increase the risk for both type 1- and 2 diabetes.

Establishing a whole school food policy

This guide has been written to help your school develop, write and implement a whole school food policy. It is designed to be easy to follow and based firmly in the context of real school life. This resource was originally developed and produced by the Health Promotion Agency for Northern Ireland as part of the School food: top marks programme and is now the responsibility of the Public Health Agency. It was jointly funded by the Department of Education and the Department of Heath, Social Services and Public Safety.

Healthy breaks: tasty tips for the under fives

Today the Public Health Agency is launching a new resource pack designed to assist nursery schools and playgroups deliver a healthy breaks scheme.All nursery schools and playgroups in Northern Ireland will receive the pack - 'Healthy breaks for pre-school children' - which includes a poster and information leaflets for parents explaining why a healthy break is so important for pre-school children and some tips and ideas for healthy nutritious breaks.Judith Hanvey, Regional Food in Schools Co-ordinator, appointed jointly by the PHA and the Department of Education, said: "Break-time snacking schemes currently operate in many pre-school settings across Northern Ireland, however they are implemented in different ways. The PHA has developed this new guidance so that any existing or future schemes have the information that they need to deliver a healthy break programme."Judith explained why a healthy break is so important for pre-school pupils."Young children have small stomachs but high requirements for energy (calories) and nutrients. This means that healthy snacks between meals are very important to make sure that they get all the nourishment they need."Childhood is also an important time to establish good eating and drinking habits for later life."Healthy eating schemes give children the knowledge and opportunity to make healthier choices."The Department of Education and Department of Health, Social Services and Public Safety recently launched 'Healthy Food for Healthy Outcomes: Food in Schools Policy', which builds on the nutritional standards which were introduced in 2007 by the Department of Education.The policy encourages a 'whole school approach' to all food and drink provided and consumed in schools. This ensures that children have the opportunity to benefit from a healthy balanced diet, which can aid learning, leading to improved educational outcomes. It also requires that every school should have their own whole-school food policy in place by September 2014. Nursery schools that receive funding from the Department of Education must follow this policy.This is also in line with the position taken by the Department of Health, Social Services and Public Safety's 10 year obesity prevention strategy, A Fitter Future for All, which aims to take a consistent approach to healthy food within early years settings.

The journey towards comprehensive school health within an aboriginal community

The purpose of this research is to describe the journey towards Comprehensive School Health at two Aboriginal elementary schools. An advocate and a healthy schools committee were identified at both schools and were responsible for developing initiatives to create a healthy school community. A case study was used to gather an in-depth understanding of Comprehensive School Health for the two schools involved. As a researcher, I functioned within the role of a participantobserver, as I was actively involved in the programs and initiatives completed in both schools. The research process included: the pilot study, ethics clearance and distribution of letters of invitation and consent forms. Data collection included 16 semi-structured, guided interviews with principals, teachers, and stupents. Participant observations included sites of the gymnasium, classroom, playgrounds, school environments, bulletin boards as well as artifact analysis of decuments such as school newsletters, physical education schedules and school handbooks. The interviews were transcribed and coded using an inductive approach which involves finding patterns, themes and categories from the data (patton, 2002). Research questions guided the findings as physical activity, physical education, nutrition and transportation were discussed. Themes developed t~rough coding were teacherstudent interactions, cultural traditions, time constraints and professional development and were discussed using a Comprehensive School Health framework.

Circulating fibrinogen but not D-dimer level is associated with vital exhaustion in school teachers

Meta-analyses have established elevated fibrinogen and D-dimer levels in the circulation as biological risk factors for the development and progression of coronary artery disease (CAD). Here, we investigated whether vital exhaustion (VE), a known psychosocial risk factor for CAD, is associated with fibrinogen and D-dimer levels in a sample of apparently healthy school teachers. The teaching profession has been proposed as a potentially high stressful occupation due to enhanced psychosocial stress at the workplace. Plasma fibrinogen and D-dimer levels were measured in 150 middle-aged male and female teachers derived from the first year of the Trier-Teacher-Stress-Study. Log-transformed levels were analyzed using linear regression. Results yielded a significant association between VE and fibrinogen (p = 0.02) but not D-dimer controlling for relevant covariates. Further investigation of possible interaction effects resulted in a significant association between fibrinogen and the interaction term "VE x gender" (p = 0.05). In a secondary analysis, we reran linear regression models for males and females separately. Gender-specific results revealed that the association between fibrinogen and VE remained significant in males but not females. In sum, the present data support the notion that fibrinogen levels are positively related to VE. Elevated fibrinogen might be one biological pathway by which chronic work stress may impact on teachers' cardiovascular health in the long run.

A study of asymptomatic bacteriuria in Egyptian school-going children.

Background: Urinary tract infections (UTI) are a common and important clinical problem in childhood. Upper urinary tract infections (i.e., acute pyelonephritis) may lead to renal scarring, hypertension, and end-stage renal disease. Despite the presence of simple and reliable methods of preliminary screening of children's urine, urinary tract infection continues to be under diagnosed. Objectives: The aim of this study was to establish prevalence rates of significant bacteriuria in asymptomatic school children by simple urine tests in comparison to standard urine culture techniques in Giza, Egypt. Patients and methods: A total of 1000 apparently healthy school going children (6-12) years, 552 boys (55.2%) and 448 girls (44.8%), were enrolled in this cross-sectional prevalence survey. Results: Overall prevalence of significant bacteriuria was 6%. Higher prevalence occurred in girls (11.4%) than boys (1.6%). Escherichia coli was isolated in 35(58%) cases (3 boys and 32 girls), Staph. aureus in 13 (22%) cases (3 boys and 10 girls), Enterobacter in 6 girls (10%), Kelbsiella pneumoniae in 3 boys (5%) and Proteus vulgaris in 3 girls (5%) Conclusion: Asymptomatic bacteriurea could be detected by urine screening program at school age. Overall prevalence of significant bacteriuria was 6%, with predominance in girls than boys.

Mudar o mundo uma (sala de) aula de cada vez

O relatório de estágio que aqui se apresenta insere-se na unidade curricular de Integração Curricular: Prática Educativa e Relatório de Estágio, do ciclo de estudos do Mestrado em Ensino do 1º e 2º Ciclo do Ensino Básico. Tem como objetivo dar a conhecer, de forma refletida e fundamentada, o percurso realizado pela mestranda no âmbito da sua intervenção educativa em contexto de Prática de Ensino Supervisionada. No presente relatório procura-se demonstrar as aprendizagens realizadas ao longo da formação académica da mestranda e decorrentes dos momentos vividos nas escolas onde realizou a PES. A importância de uma boa relação escola-família, a importância e a dificuldade da diferenciação pedagógica e de uma equilibrada relação professor-aluno foram algumas das temáticas que a professora estagiária achou fundamental aprofundar depois dos momentos vividos nas escolas. Apesar destas vivências terem sido fundamentais no crescimento e aprendizagem da mestranda, o seu percurso já se vem a contruir há muitos anos pois, apesar de ser professora não ter sido um sonho de criança, ensinar foi algo que esteve sempre presente dentro de si, mesmo sem se aperceber. Olhando para trás, é possível perceber que existiram vários indícios de paixão pelo ensino, ainda que a mestranda não os tenha relacionado à profissão de professor, tendo sido esses a conduzir a mestranda ao caminho que realmente a faz feliz: SER PROFESSORA.

A needs assessment of public health professionals: supporting the implementation of Ontario 2010 revised elementary health and physical education curriculum

Based on the Comprehensive School Health framework, Ontario's Foundations for a Healthy School (2009) outlines an integrated approach to school health promotion. In this approach the school, community and partners (including public health) are fully engaged With a common goal of youth health. With the recent introductions of the Ontario Public Health Standards (2009) and the revised elementary health and physical education curriculum (2010), the timing for a greater integration of public health with schools is ideal. A needs assessment was conducted to identify the perceived support required by public health professionals to implement the mandates of both policy documents in Ontario. Data was collected for the needs assessment through facilitated discussions at a provincial roundtable event, regional focus groups and individual interviews with public health professionals representing Ontario's 36 public health units. Findings suggest that public health professionals perceive that they require increased resources, greater communication, a clear vision of public health and a suitable understanding of the professional cultures in which they are surrounded in order to effectively support schools. This study expands upon these four categories and the corresponding seventeen themes that were uncovered during the research process.

Caracterización de los hábitos alimentarios en población pediátrica de cuatro instituciones escolares

Introducción: La obesidad infantil ha venido en aumento en los últimos años y Colombia no es ajena a esta problemática. Uno de los lugares para intervención son los planteles educativos, en los cuales los escolares son quienes escogen sus alimentos. En el presente estudio se pretendió caracterizar los hábitos alimentarios de una población pediátrica en cuatro instituciones educativas, con el fin de conocer las prioridades infantiles en cuanto a la escogencia de los alimentos, y por ende generar recomendaciones. Metodología: Se realizó un estudio descriptivo multicéntrico que presenta los resultados de encuestas dirigidas a escolares entre 8 y 18 años, usuarios de tiendas escolares. Se realizó un análisis descriptivo de acuerdo a las preferencias de alimentación por institución, por género y por edad entre otros. Resultados: Se incluyeron un total de 512 escolares. La distribución por género y edad fue similar en las cuatro instituciones educativas. Entre los alimentos de preferencia predominaron los alimentos empaquetados, pizza, helados y en menor proporción las frutas. En cuanto a las bebidas predominó la gaseosa y té en botella. Entre las razones para escoger los alimentos predominó “el sabor” seguido de la “facilidad y rapidez” para su consumo; y la principal razón para no escoger los alimentos fue el precio. Discusión: Es necesario hacer intervención desde una temprana edad para generar hábitos de alimentación saludable y equilibrada, al igual que se debería tener un programa de detección de hábitos alimentarios inadecuados en las instituciones escolares para así poder combatirlos.

Equações preditivas para as pressões respiratórias máximas de crianças brasileiras

I ntroduction: The assessment of respiratory muscle strength is important in the diagnosis and monitoring of the respiratory muscles weakness of respiratory and neuromuscular diseases. However, there are still no studies that provide predictive equations and reference values for maximal respiratory pressures for children in our population. Aim: The purpose of this study was to propose predictive equations for maximal respiratory pressures in healthy school children. Method: This is an observational cross-sectional study. 144 healthy children were assessed. They were students from public and private schools in the city of Natal /RN (63 boys and 81 girls), subdivided in age groups of 7-8 and 9-11 years. The students presented the BMI, for age and sex, between 5 and 85 percentile. Maximal respiratory pressures were measured with the digital manometer MVD300 (Globalmed ®). The maximal inspiratory pressure (MIP) and maximal expiratory pressures (MEP) were measured from residual volume and total lung capacity, respectively. The data were analyzed using the SPSS Statistics 15.0 software (Statistical Package for Social Science) by assigning the significance level of 5%. Descriptive analysis was expressed as mean and standard deviation. T'Student test was used for unpaired comparison of averages of the variables. The comparison of measurements obtained with the predicted values in previous studies was performed using the paired t'Student test. The Pearson correlation test was used to verify the correlation of MRP's with the independent variables (age, sex, weight and height). For the equations analysis the stepwise linear regression was used. Results: By analyzing the data, we observed that in the age range studied MIP was significantly higher in boys. The MEP did not differ between boys and girls aged 7 to 8 years, the reverse occurred in the age between 9 and 11 years. The boys had a significant increase in respiratory muscle strength with advancing age. Regardless sex and age, MEP was always higher than the MIP. The reference values found in this study are similar to a sample of Spanish and Canadian children. The two models proposed in previous studies with children from other countries were not able to consistently predict the values observed in this studied population. The variables sex, age and weight correlated with MIP, whereas the MEP was also correlated with height. However, in the regression models proposed in this study, only gender and age were kept exerting influence on the variability of maximal inspiratory and expiratory pressures. Conclusion: This study provides reference values, lower limits of normality and proposes two models that allow predicting, through the independent variables, sex and age, the value of maximal static respiratory pressures in healthy children aged between 7 and 11 years old

Methods and Participant Characteristics of a Randomized Intervention to Promote Physical Activity and Healthy Eating Among Brazilian High School Students: The Saude na Boa Project

Background: A cross-cultural, randomized study was proposed to observe the effects of a school-based intervention designed to promote physical activity and healthy eating among high school students in 2 cities from different regions in Brazil: Recife and Florianopolis. The objective of this article is to describe the methodology and subjects enrolled in the project. Methods: Ten schools from each region were matched and randomized into intervention and control conditions. A questionnaire and anthropometry were used to collect data in the first and last month of the 2006 school year. The sample (n = 2155 at baseline; 55.7% females; 49.1% in the experimental group) included students 15 to 24 years, attending nighttime classes. The intervention focused on simple environmental/organizational changes, diet and physical activity education, and personnel training. Results: The central aspects of the intervention have been implemented in all 10 intervention schools. Problems during the intervention included teachers' strikes in both sites and lack of involvement of the canteen owners in schools. Conclusions: The Saude no Boa study provides evidence that public high schools in Brazil represent an important environment for health promotion. Its design and simple measurements increase the chances of it being sustained and disseminated to similar schools in Brazil.

Vitamin A deficiency among Brazilian school-aged children in a healthy child service

Background/Objectives: Vitamin A deficiency (VAD) is a world public health problem contributing to the increase in childhood morbidity and mortality in developing countries and severe deficiency of vitamin A may lead to xerophthalmia and blindness. The objective of this study was to determine the prevalence of VAD among Brazilian school-aged children attended at a primary health unit and to verify if some considered risk factor was associated with VAD in this group. Subjects/Methods: A descriptive prospective transverse study was conducted on 103 randomly selected children. A total of 54 boys and 49 girls aged 5.5-11 years had the relative dose-response (RDR) test performed on. Possible ocular alterations related to vitamin A and the status of anemia, serum zinc, some acute-phase proteins, and anthropometric situation were determinate by an analytic design. Results: No child presented xerophthalmia. Serum retinol values lower than 1.05 and 0.7 mu moll(-1), respectively were found in 26.2 and 5.8% of the children. The prevalence of hypovitaminosis detected by RDR test was 20.4%. The following variables and their relationship with VAD were evaluated: sex (P = 0.33; 95% confidence interval 0.61-4.34), weight and height (P >= 0.5), hemoglobin (P = 0.15), C-reactive protein (P = 0.56; 95% confidence interval 0.75-18.26), alpha-1-acid-glycoprotein (P = 0.56; 95% confidence interval 0.15-15.42) and serum zinc (P = 0.31). None of these variables was related to VAD. Conclusions: In this population, the prevalence of VAD detected could be considered a public health problem. School-aged children can be considered at risk for VAD mainly of a subclinical level, even without some associated risk factors.
