•We assessed young bystanders’ behavioural intentions towards Facebook harassment.•Contextual factors were manipulated in an experimental scenario design.•Incident severity and other bystanders’ ...identity influenced helping intentions.•Other bystanders’ identity and behaviour influenced joining in the bullying.•Gender influenced helping and reinforcing intentions.
Cyberbullying on social network sites poses a significant threat to the mental and physical health of victimized adolescents. Although the role of bystanders in solving bullying instances has been demonstrated repeatedly in research on traditional bullying, their role in cyberbullying remains relatively understudied. Therefore, we set up an experimental scenario study in order to examine the influence of contextual factors (severity of the incident, identity and behaviour of other bystanders) on bystanders’ behavioural intentions to help the victim or reinforce the bully in cases of harassment on Facebook. Four hundred and fifty-three second year students of Flemish secondary schools participated in the study. The results on the one hand showed that bystanders had higher behavioural intentions to help the victim when they witnessed a more severe incident. Incident severity also interacted with other bystanders’ identity in influencing behavioural intentions to help the victim. On the other hand, bystanders had higher behavioural intentions to join in the bullying when other bystanders were good friends rather than acquaintances. In addition, an interaction effect was found between other bystanders’ identity and behaviour on behavioural intentions to join in the bullying. Furthermore, both helping and reinforcing behavioural intentions differed according to gender.
Objective
This longitudinal study investigated the interrelationship between children's weight status and level of gross motor coordination over time, taking baseline physical activity (PA) into ...account as a possible mediator.
Methods
Baseline measurements were collected in 2517 children (5‐13 years, 52.8% boys), including (1) body height and weight to calculate body mass index (BMI) z‐scores, (2) gross motor coordination using the Körperkoordinationstest für Kinder (KTK), (3) total PA estimated by a questionnaire. At follow‐up, 754 participants (7‐13 years, 50.8% boys) underwent anthropometric and KTK assessments again. Two hypothesized partial mediation models (i.e., KTK ↔ PA ↔ BMI z‐score) were examined by multiple linear mixed models.
Results
A lower performance on the KTK at baseline significantly predicted an increase in BMI z‐score (B = −0.003, P = 0.027). Conversely, a higher baseline BMI z‐score also predicted a decrease in KTK performance (B = −1.792, P < 0.001). Since total PA at baseline was not significantly related to initial KTK performance (B = 1.628, P = 0.134) nor BMI z‐score (B = 25.312, P = 0.130), its mediating effect was not further explored.
Conclusions
Our results strongly suggest that children's weight status negatively influences future level of gross motor coordination, and vice versa. Prevention and intervention initiatives should consider this reciprocal causal relationship across developmental time.
The present study aimed to describe accelerometer-based physical activity levels in 4- and 5-year-old children (N = 76) on 2 weekdays and 2 weekend days. The children were sedentary for 9.6 hr (85%) ...daily, while they engaged in moderate to vigorous physical activity (MVPA) for 34 min (5%). Only 7% of the children engaged in MVPA for 60 min per day, and only 26% reached the standard of 120 min of total activity. Their engagement in MVPA did not significantly differ between weekend and weekdays. Mean activity counts and minutes in MVPA did not differ between genders. Physical activity levels in this sample of preschool children were far lower than recommended.
Most previous studies examining physical activity in Public Open Spaces (POS) focused solely on the physical environment. However, according to socio-ecological models the social environment is ...important as well. The aim of this study was to determine which social and physical environmental factors affect adolescents' visitation and physical activity in POS in low-income neighbourhoods. Since current knowledge on this topic is limited, especially in Europe, qualitative walk-along interviews were used to obtain detailed and context-specific information. Participants (n = 30, aged 12-16 years, 64% boys) were recruited in POS in low-income neighbourhoods in Brussels, Ghent and Antwerp (Belgium). Participants were interviewed while walking in the POS with the interviewer. Using this method, the interviewer could observe and ask questions while the participant was actually experiencing the environment. All audio-recorded interviews were transcribed and analysed using Nvivo 10 software and thematic analysis was used to derive categories and subcategories using a grounded theory approach. The most important subcategories that were supportive of visiting POS and performing physical activity in POS were; accessibility by foot/bicycle/public transport, located close to home/school, presence of (active) friends and family, cleanliness of the POS and features, availability of sport and play facilities, large open spaces and beautiful sceneries. The most important subcategories that were unsupportive of visiting POS and physical activity in POS were; presence of undesirable users (drug users, gangs and homeless people), the behaviour of other users and the cleanliness of the POS and features. Social factors appeared often more influential than physical factors, however, it was the combination of social and physical factors that affected adolescents' behaviour in POS. Easily accessible POS with high quality features in the proximity of adolescents' home or school may stimulate physical activity, if adolescents also experience a safe and familiar social environment.

To explore gender-specific variations related to activity intensity in the relationship between physical activity (PA) and mental health (MH). Evaluating whether psychological well-being enhances ...with increases in PA at recommended levels and above, in the general population.
Cross-sectional.
Population-based, representative for Belgium.
A total of 6803 adults aged 25-64 years from the Belgian National Health Interview Survey.
Multiple logistic regression analyses showed that clearly different intensity levels characterised the PA that associated with MH in women and men. In men, inverse associations existed between participation in vigorous-intensity PA and feelings of depression (OR = 0.580; 95 % CI 0.405, 0.830), anxiety (OR = 0.547; 95 % CI 0.364, 0.821) and symptoms of somatisation (OR = 0.590; 95 % CI 0.398, 0.874). In women, positive associations existed between walking and emotional well-being (OR = 1.202; 95 % CI 1.038, 1.394) and inverse associations between participation in moderate-intensity PA and symptoms of somatisation (OR = 0.737; 95 % CI 0.556, 0.977). Secondary analyses confirmed that differences in psychological complaints were significant for vigorous PA in men, and for moderate PA in women, whereas differences in emotional well-being were significant for walking exclusively in women.
In the general population, the PA-MH relationship is always positive, regardless of activity intensity. In men, it addresses complaints (symptoms, palpable discomfort) and the optimal PA intensity is high. In women, it addresses complaints, but also distress (lowered mood, disturbing anxiety, altered well-being) and the PA intensity is mild.
We examined the mediating role of physical activity on the relationships of walkability with Flemish older adults' health outcomes. In low income neighborhoods, residents of high walkable ...neighborhoods had a 1.5kg/m2 lower BMI than low walkable residents. Of this difference 0.3kg/m2 (19%) and 0.2kg/m2 (12%) were explained through walking for transport and MVPA, respectively. Similar findings were observed for waist circumference. Walkability did not relate to functional performance or quality of life. Walkable neighborhoods may benefit older adults’ health, especially in low income neighborhoods. More research in other contexts is warranted to confirm current findings.
•High walkability might promote health, especially in low income neighborhoods.•In low income neighborhoods, high walkability related to a healthier weight status.•Physical activity partially mediated this walkability-health relationship.•Several inconsistent mediations were observed for other health outcomes.•Other (unobserved) mediators might offset the positive effects of physical activity.
We studied the implementation and associated factors of strategies (e.g. sports after school and during lunch break, active schoolyards, active school commuting) and organizational principles (e.g. ...safe bike racks, pupil involvement) that facilitate the physical activity (PA)-promoting role of schools. Key representatives of 111 elementary and 125 secondary schools filled out an online survey. Less than half of the elementary schools organized sports during lunch-break or after school. In secondary schools the least implemented strategies were the promotion of active school commuting and after-school sports. In general pupil, parental and community involvement scored low. Better knowledge of community schools and having attended in-service training were associated with higher implementation scores in elementary and secondary schools. Better implementation of the strategies was found in larger schools. Participation in activities from the School Sports Association and more perceived interest from parents and the school board were also associated with higher implementation scores. In conclusion, knowledge of community schools and in-service training next to sufficient human resources are potential key factors to promote PA. Efforts are needed to convince and help schools to increase parental and pupil involvement and to build a policy on school-community partnerships.
The study aim was to objectively assess levels of sedentary time, light, moderate and vigorous physical activity (PA) among 10-12 year olds across five European countries and to examine differences ...in sedentary time and PA according to gender and country.
686 children (mean age = 11.6 ± 0.8 years, 53% girls, mean BMI = 19.0 ± 3.4 kg/m(2)) from Belgium, Greece, Hungary, the Netherlands and Switzerland wore Actigraph accelerometers and had at least 2 weekdays with minimum 10 h-wearing time and 1 weekend day with minimum 8 h-wearing time. Data were analyzed using multivariate analyses of covariance.
Girls spent significantly more time sedentary (500 minutes/day) than boys (474 minutes/day) and significantly less time in light (267 minutes/day) and moderate-to-vigorous PA (32 minutes/day) than boys (284 minutes/day; 43 minutes/day respectively; p < 0.001). 4.6% of the girls and 16.8% of the boys met moderate-to-vigorous PA recommendations of at least 60 minutes/day. Greek boys were more sedentary (510 minutes/day; all at p < 0.05) than other boys. Dutch girls were less sedentary (457 minutes/day; all at p < 0.05) than other girls. Swiss girls displayed more moderate-to-vigorous PA (43 minutes/day; at p < 0.05) than other girls.
Large proportions of children across different European countries did not meet PA recommendations and spent a lot of time sedentary. Mean time spent in moderate-to-vigorous PA was significantly lower than the recommended 60 minutes. Obesity prevention programmes focusing on both decreasing sedentary time and increasing light, moderate and vigorous PA are needed for European children, particularly girls.
Current knowledge on the relationship between the physical environment and walking for transportation among older adults (≥ 65 years) is limited. Qualitative research can provide valuable information ...and inform further research. However, qualitative studies are scarce and fail to include neighborhood outings necessary to study participants' experiences and perceptions while interacting with and interpreting the local social and physical environment. The current study sought to uncover the perceived environmental influences on Flemish older adults' walking for transportation. To get detailed and context-sensitive environmental information, it used walk-along interviews.
Purposeful convenience sampling was used to recruit 57 older adults residing in urban or semi-urban areas. Walk-along interviews to and from a destination (e.g. a shop) located within a 15 minutes' walk from the participants' home were conducted. Content analysis was performed using NVivo 9 software (QSR International). An inductive approach was used to derive categories and subcategories from the data.
Data were categorized in the following categories and subcategories: access to facilities (shops & services, public transit, connectivity), walking facilities (sidewalk quality, crossings, legibility, benches), traffic safety (busy traffic, behavior of other road users), familiarity, safety from crime (physical factors, other persons), social contacts, aesthetics (buildings, natural elements, noise & smell, openness, decay) and weather.
The findings indicate that to promote walking for transportation a neighborhood should provide good access to shops and services, well-maintained walking facilities, aesthetically appealing places, streets with little traffic and places for social interaction. In addition, the neighborhood environment should evoke feelings of familiarity and safety from crime. Future quantitative studies should investigate if (changes in) these environmental factors relate to (changes in) older adults' walking for transportation.
This study examined the effect of a 10 and 20% meal price increase when choosing French fries and a 10 and 20% meal price reduction when choosing fruit for dessert on university students' purchasing ...behaviour in an on-campus restaurant. The moderating effect of gender was also investigated. Secondly, this study aimed at gaining further insight into reasons why these price manipulations did or did not change students' purchasing behaviour.
This two-phased mixed-methods study was conducted in a Belgian on-campus university restaurant with approximately 1200 to 1300 student visitors per day. In a first phase (French fries experiment), data were collected during a control week (no price manipulation) and two separate intervention weeks (10 and 20% meal price increase when students chose French fries). In a second phase (fruit experiment), following the same protocol but carried out a few weeks later, meal prices were reduced by 10 and 20% when students chose fruit for dessert. French fries and fruit sale counts relative to the total number of items sold were used as outcome measure. Short interviews were conducted in convenient subsamples of student customers to assess influences on food choice.
Increasing the meal price by 10 and 20% when choosing French fries was associated with respective 10.9 and 21.8% absolute reductions in French fries purchases, while reducing the meal price by 10 and 20% when choosing fruit for dessert was associated with absolute increases in fruit purchases of respectively 25.1 and 42.4% (all p<0.001). No moderating effect of gender was detected. Besides price, food/taste preference, eating habits, health, availability and accessibility, and body satisfaction influenced students' food choices, with taste being the most frequently mentioned factor.
Pricing may be a promising strategy to improve university students' eating behaviour. The likelihood of intervention success may increase when combining pricing strategies with offering healthy, tasty and meal matching starchy alternatives to French fries and offering a variety of fresh and appealing fruits.
