The relationship of schools to emotional health and bullying

Objectives:  

To examine the extent to which school climate and school pressure could predict other aspects of adolescents’ lives, most particularly their emotional health and bullying. Furthermore, the study sought to investigate if these relationships were consistent across countries.     

The application of a social cognition model in explaining fruit intake in Austrian, Norwegian and Spanish schoolchildren using structural equation modelling

Background  

The aim of this paper was to test the goodness of fit of the Attitude – Social influence – self-Efficacy (ASE) model in explaining schoolchildren's intentions to eat fruit and their actual fruit intake in Austria, Norway and Spain; to assess how well the model could explain the observed variance in intention to eat fruit and in reported fruit intake and to investigate whether the same model would fit data from all three countries.     

Combination of fish oil and fish protein hydrolysate reduces the plasma cholesterol level with a concurrent increase in hepatic cholesterol level in high-fat-fed Wistar rats

ObjectiveThis study investigated the potential additive or synergistic effect of fish oil (FO) and fish protein hydrolysate (FPH) on cholesterol concentration in plasma and the liver.MethodsMale Wistar rats were fed high-fat diets (30% fat, 20% protein, wt/wt) containing FO (5%), FPH (10%), a combination of FO and FPH, or a high-fat control diet. After 7 wk of feeding, the rats were fasted for 12 h before lipid levels in plasma and the liver and hepatic activities of acyl-coenzyme A:cholesterol acyltransferase, 3-hydroxy-3-methylglutaryl coenzyme A reductase, and fatty acid synthase were measured.ResultsThe combination of FO and FPH in the diet profoundly reduced the plasma cholesterol level, mainly due to lowering of high-density lipoprotein cholesterol, whereas the hepatic total cholesterol concentration was elevated compared with control rats and rats fed diets containing FPH or FO alone. The elevated cholesterol concentration in the liver was caused by an increased amount of cholesteryl esters and was in correlation to an increased activity of acyl-coenzyme A:cholesterol acyltransferase. There was a reduced fatty acid synthase activity that could lead to a reduced lipogenesis in the rats fed a combination of FO and FPH.ConclusionA dietary combination of FO and FPH resulted in lower levels of plasma cholesterol and higher levels of hepatic cholesterol compared with dietary FO or FPH alone. Further studies are warranted to confirm whether the hypocholesterolemic effect was due to a reduced secretion of very low-density lipoprotein from the liver.     

Understanding the dynamics emerging from the interplay among poor mental wellbeing,energy balance-related behaviors,and obesity prevalence in adolescents: A simulation-based study

Both obesity and poor mental wellbeing have a high prevalence in European youth. Adolescents in six countries identified mental wellbeing factors as main drivers of youth obesity through systems mapping. This study sought to (1) explore the dynamics of the interplay between poor mental wellbeing, energy balance-related behaviors, and adolescent overweight and obesity prevalence and (2) test the effect of intervention point scenarios to reduce adolescent obesity. Drawing on the youth-generated systems maps and a literature synthesis, we built a simulation model that represents the links from major feedback pathways for poor mental wellbeing to changes in dietary, physical activity, and sleep behaviors. The model was calibrated using survey data from Norway, expert input, and literature and shows a good fit between simulated behavior and available statistical data. The simulations indicate that adolescent mental wellbeing is harmed by socio-cultural pressures and stressors, which trigger reinforcing feedback mechanisms related to emotional/binge eating, lack of motivation to engage in physical activity, and sleep difficulty. Targeting a combination of intervention points that support a 25% reduction of pressure on body image and psychosocial stress showed potentially favorable effects on mental wellbeing—doubling on average for boys and girls and decreasing obesity prevalence by over 4%.     

Health–promoting schools in Australia: models and measurement

Abstract: Schools represent a very attractive setting for health promotion. Most children and young people attend school, professional educators are in place, and most school communities are microcosms of the larger community, providing opportunities for children to develop and practise the skills necessary to support a healthy life–style. In response to this opportunity, the precepts of contemporary health promotion have been synthesised into the 'health—promoting school' model, which is guided by a holistic view of health and by the principles of equity and empowerment. Although there are different conceptions of the model, the key components are: the formal curriculum; school ethos (the social climate); the physical environment; the policies and practices of the school; school health services; and the school–home–community interaction. The health–promoting school model offers a comprehensive, systematic approach to health promotion in the school setting, which is widely accepted internationally. There have been few studies in Australia that have attempted to determine the prevalence of activities related to the model or to evaluate interventions. Unfortunately, conceptual and practical advances have far outstripped the development of research and evaluation instruments. There is an urgent need to create valid research tools to support the development and implementation of this potentially fruitful health promotion model.     

The Relationship Between School Perceptions and Psychosomatic Complaints: Cross-Country Differences Across Canada, Norway, and Romania

This study examined the predictive value of school climate and peer support for psychosomatic complaints, perceived academic achievement, and school satisfaction in Canada, Norway, and Romania. While the three countries used the same measures of each construct, the questionnaires were written in three different languages. Thus, we first established the linguistic equivalence of the instruments across the three countries. Having established linguistic equivalence, we next examined the extent to which the patterns of relationship were similar across the countries and for two age groups (13- and 15-year-olds). There were similar cross-national patterns in relationships with stronger links between school climate and the three outcomes than between peer support and the outcomes. The peer support–perceived academic achievement path was in all instances weak or non-significant. With respect to age differences, none were observed in Canada and Norway, but age differences were seen in Romania.     

Exercise Self-Efficacy and patient global assessment were associated with 6-min walk test distance in persons with rheumatoid arthritis

Introduction

Low functional capacity is related to future loss of daily function and cardiovascular events. The present study explored the associations of patient-reported outcome measures (PROMs) and disease-specific measures with functional capacity as measured by the 6-min walk test (6MWT) in persons with rheumatoid arthritis (RA).

Methods

Seventy-nine participants from rheumatology outpatient clinics were included. The distance walked during the 6MWT (6MWD) was the dependent variable in multivariable regression analyses. Model 1 included the independent variables sex, age (in tertiles to improve model fit), and body mass index (BMI). Building on Model 1, Model 2 added smoking, patient global assessment (PGA), Exercise Self-Efficacy, Hospital Anxiety and Depression Scale’s Depression score, and Cohen’s Perceived Stress Scale score, whereas Model 3 added smoking, disease duration, present use of glucocorticosteroids, seropositivity, Disease Activity Score 28—C-Reactive Protein (DAS28-CRP), and a comorbidity variable.

Results

Median age was 65 years, 76% were female, and median 6MWD was 493 m. In Model 1, BMI and age were significantly associated with the 6MWD (R² = 0.42). In Model 2, PGA and Exercise Self-Efficacy were also significantly associated with the 6MWD, with standardized regression coefficients of − 0.21 (p = 0.03) and 0.26 (p = 0.004) respectively (R² = 0.54). The RA-specific variables in Model 3 were not significantly associated with the 6MWD (R² = 0.49).

Conclusion

The PROMs PGA and Exercise Self-Efficacy were significantly associated with functional capacity as measured by the 6MWT in persons with RA, whereas disease-specific measures such as DAS28-CRP and disease duration were not.
