Cross-national time trends in bullying victimization in 33 countries among children aged 11, 13 and 15 from 2002 to 2010.

BACKGROUND Bullying among children and adolescents is a public health concern; victimization is associated with psychological and physical health problems. The purpose of this study is to examine temporal trends in bullying victimization among school-aged children in Europe and North America. METHODS Data were obtained from cross-sectional self-report surveys collected as part of the Health Behaviour in School-aged Children (HBSC) study from nationally representative samples of 11-, 13- and 15-year-olds, from 33 countries and regions which participated in the 2001-02, 2005-06 and 2009-10 surveys. Responses from 581 838 children were included in the analyses. Binary logistic regression was used for the data analyses. RESULTS The binary logistic regression models showed significant decreasing trends in occasional and chronic victimization between 2001-02 and 2009-10 across both genders in a third of participating countries. One country reported significant increasing trends for both occasional and chronic victimization. Gender differences in trends were evident across many countries. CONCLUSION Overall, while still common in many countries, bullying victimization is decreasing. The differences between countries highlight the need to further investigate measures undertaken in countries demonstrating a downward trend.

Food for thought: analysing the internal and external school food environment

Purpose – Availability and access to food is a determinant of obesity. The purpose of this paper is to examine food availability within and outside of post-primary schools in Ireland. Design/methodology/approach – Data on the internal school food environment were collected from 63 post-primary schools using questionnaires. The external school food environment for these 63 schools was assessed by mapping food businesses within 1 km of schools, using a Geographic Information System (GIS). Food businesses were categorised based on type of food sold. Findings – A total of 68.3 per cent of schools had a canteen, 52.5 per cent had a small food shop and 37.1 per cent had a vending machine. A total of 32.7 per cent of schools reported selling chips (French fries) in their canteen while 44.2 per cent of schools reported selling energy-dense nutrient-poor foods in their school shop. Of the schools surveyed, there was an average of 3.89 coffee shops and sandwich bars, 3.65 full service restaurants, 2.60 Asian and other “ethnic” restaurants, 4.03 fast food restaurants, 1.95 supermarkets, 6.71 local shops and 0.73 fruit and vegetable retailers within a 1 km radius of the post-primary schools. Findings are presented by geography (urban/rural), disadvantage (Delivering Equality of Opportunity in School (DEIS)/non DEIS), gender (girls/boys/mixed) and food policy in place at the school (yes/no). Practical implications – These data will facilitate schools working on the framework for Health Promoting Schools in Ireland. Social implications – This work can contribute to current discussions on restricting accessibility to certain foods and food premises for school children. Originality/value – The study explores the internal and external school food environment. GIS have been used to link the external food environment to specific schools thus allowing a comprehensive analysis of the schools’ food environment. To the authors knowledge, this is the first time that both environments are explored simultaneously.

Temporal and spatial distribution of human cryptosporidiosis in the west of Ireland 2004-2007.

BackgroundCryptosporidiosis is increasingly recognised as a cause of gastrointestinal infection in Ireland and has been implicated in several outbreaks. This study aimed to investigate the spatial and temporal distribution of human cryptosporidiosis in the west of Ireland in order to identify high risk seasons and areas and to compare Classically Calculated (CC) and Empirical Bayesian (EB) incidence rates. Two spatial scales of analysis were used with a view to identifying the best one in assessing geographical patterns of infection. Global Morans I and Local Morans I tests of autocorrelation were used to test for evidence of global and local spatial clustering.ResultsThere were statistically significant seasonal patterns of cryptosporidiosis with peaks in spring and an increasing temporal trend. Significant (p < 0.05) global spatial clustering was observed in CC rates at the Electoral Division (ED) level but not in EB rates at the same level. Despite variations in disease, ED level was found to provide the most accurate account of distribution of cryptosporidiosis in the West of Ireland but required spatial EB smoothing of cases. There were a number of areas identified with significant local clustering of cryptosporidiosis rates.ConclusionThis study identified spatial and temporal patterns in cryptosporidiosis distribution. The study also showed benefit in performing spatial analyses at more than one spatial scale to assess geographical patterns in disease distribution and that smoothing of disease rates for mapping in small areas enhances visualisation of spatial patterns. These findings are relevant in guiding policy decisions on disease control strategies.

The relationship between cyberbullying and friendship dynamics on adolescent body dissatisfaction: A cross-sectional study:

The relationship between cyberbullying and friendship dynamics on adolescent body dissatisfaction was examined. Data from the Irish contribution to the international cross-sectional 2013/2014 Health Behaviour in School-aged Children study were used. Results showed that girls were three times more likely than boys to report that their body is too fat, and adolescents who were cyberbullied were almost twice as likely as adolescents who were not cyberbullied to consider themselves too fat. Stronger friendship dynamics were associated with decreased levels of body dissatisfaction, and friendship dynamics were found to partially mediate the relationship between cyberbullying and body dissatisfaction.
