Physical fitness and physical behavior in (wheelchair-using) youth with spina bifida

In this thesis we analyzed clinimetric measurement properties of physical fitness tests in wheelchair-using youth with SB. Furthermore, the amount of physical behavior in wheelchair-using youth with SB was quantified and associations with age, gender, VO2peak and Hoffer classification were evaluated. Finally, we described the factors associated with physical behavior in youth with SB and youth with physical disabilities, after which the evidence of interventions to improve physical behavior in youth with physical disabilities was analyzed. This last chapter presents the theoretical and clinical implications. At the end, methodological considerations and directions for further research will be discussed after which the overall conclusion is presented.

Emotion measurement in tourism destination marketing : a comparative electroencephalographic and behavioral study

It is commonly assumed that TV commercials successfully influence affective tourism destination image by coupling positive emotions to a destination. In this study we record emotional responses to destination pictures before and after viewing a destination TV commercial from participants’ brains using electroencephalography (EEG). A control group of participants watched the same destination pictures, and an unrelated TV commercial. Emotion-related event-related potential (ERP) components, the P2 and LPP, were derived from the EEG. For the participants that watched the destination TV commercial, the P2 and the LPP were larger in response to destination pictures after compared to before having watched the TV commercial. This effect was not observed in the control group. In a behavioral version of the same experiment, we did not observe any effects in the self-report data. It is concluded that ERP methodology is a useful tool to complement the toolbox of tourism marketing researchers

Effectiveness of school-based physical activity and nutrition interventions with direct parental involvement on children’s BMI and energy balance-related behaviors

Background: The aims of this systematic review were to study the effectiveness of primary school-based physical activity, sedentary behavior and nutrition interventions with direct parental involvement on children’s BMI or BMI z-score, physical activity, sedentary behavior and nutrition behavior and categorize intervention components into targeted socio-cognitive determinants and environmental types using the Environmental Research framework for weight Gain prevention. Methods: In March 2018, a systematic search was conducted in four electronic literature databases. Articles written in English about effectiveness studies on school-based interventions with direct parental involvement targeting 4–12 year olds were included. Interventions with indirect parental involvement, interventions not targeting the school environment, and pilot studies were excluded. Study and intervention characteristics were extracted. Study quality and study effectiveness were assessed and effect sizes (Cohen’s d) were calculated for the outcome measures. Types of socio-cognitive factors and environmental types targeted were distinguished. Results: In total, 25 studies were included. Most studies on BMI or BMI z-score, physical activity and sedentary behavior found favorable results: 61.1%, 81.1% and 75%, respectively. Results regarding nutrition behavior were inconclusive. Methodological study quality varied. All interventions targeted multiple environmental types in the school and family environment. Five targeted socio-cognitive determinants (knowledge, awareness, attitude, self-efficacy and intrinsic motivation) of the children were identified. No consistent pattern was found between either type of environment targeted, number of type of environment targeted, or the child’s targeted socio-cognitive determinants and intervention effectiveness. Discussion: School-based interventions with direct parental involvement have the potential to improve children’s weight status, physical activity and sedentary behavior. Based on the results, it is recommended that school-based interventions with direct parental involvement target more than one EBRB, last at least one year, and focus particularly on the physical and social environment within both the school and the family environment

A cross-sectional study on the relation between the family nutrition climate and children’s nutrition behavior

Background: Parents influence their children’s nutrition behavior. The relationship between parental influences and children’s nutrition behavior is often studied with a focus on the dyadic interaction between the parent and the child. However, parents and children are part of a broader system: the family. We investigated the relationship between the family nutrition climate (FNC), a family-level concept, and children’s nutrition behavior. Methods: Parents of primary school-aged children (N = 229) filled in the validated family nutrition climate (FNC) scale. This scale measures the families’ view on the consumption of healthy nutrition, consisting of four dierent concepts: value, communication, cohesion, and consensus. Parents also reported their children’s nutrition behavior (i.e., fruit, vegetable, water, candy, savory snack, and soda consumption). Multivariate linear regression analyses, correcting for potential confounders, were used to assess the relationship between the FNC scale (FNC-Total; model 1) and the dierent FNC subscales (model 2) and the child’s nutrition behavior. Results: FNC-Total was positively related to fruit and vegetable intake and negatively related to soda consumption. FNC-value was a significant predictor of vegetable (positive) and candy intake (negative), and FNC-communication was a significant predictor of soda consumption (negative). FNC-communication, FNC-cohesion, and FNC-consensus were significant predictors (positive, positive, and negative, respectively) of water consumption. Conclusions: The FNC is related to children’s nutrition behavior and especially to the consumption of healthy nutrition. These results imply the importance of taking the family-level influence into account when studying the influence of parents on children’s nutrition behavior.

Confessions of a 'guilty' couch potato understanding and using context to optimize binge-watching behavior

Viewers more frequently watch television content whenever they want, using devices they prefer, which stimulated 'Binge-watching' (consecutive viewing of television programs). Although binge-watching and health concerns have been studied before, the context in which binge-watching takes place and possibilities to use context to optimize binge-watching behavior have not. An in-situ, smartphone monitoring survey among Dutch binge-watchers was used to reveal context factors related to binge-watching and wellbeing. Results indicate that binge-watching is a solitary activity that occurs in an online socially active context. The amount of time spent binge-watching (number of episodes) correlates with the amount of free time and plays an important role in the effect of binge-watching on emotional wellbeing. Considering the difficulty viewers have to create an optimal viewing experience, these context factors are used as a framework to be able to design and promote a recommendation tool for TV streaming services to create a more optimal binge-watching experience.
