Although health game interventions seemingly enhance the physical activity self-efficacy of children and have potential as a means of increasing physical activity, more rigorous research is needed to clarify how effective such interventions are in the longer run to contribute to the development of game-based interventions.

Effective, evidence-based, and interesting methods are needed for children's health promotion. Digital games can be such a method, but there is need for a summary of the evidence on the effectiveness of digital games in promoting children's health. The aim of this review of reviews was to evaluate the quality of systematic reviews, to summarize the evidence in systematic reviews and reviews related to the effectiveness of digital games in children's health promotion, and to identify gaps in knowledge. A systematic literature search was conducted in May-August 2013 from relevant databases, and 1178 references were found. In total, 15 systematic reviews and reviews met the inclusion criteria. Most of the systematic reviews were found to be medium quality on the AMSTAR checklist. Most commonly, systematic reviews and reviews evaluated active videogames. According to the results, evidence of the highest level and quality seems to support an increase in physical activity to light to moderate levels and energy expenditure, especially when playing active videogames that require both upper and lower body movements. In addition, sedentary games were shown to have potential in children's health education, especially in supporting changes in asthma- and diabetes-related behavior and in dietary habits. However, there are still several gaps in the knowledge. There is a need for further high-quality systematic reviews and research in the field of health games.

BackgroundSelf-quantification of health parameters is becoming more popular; thus, the validity of the devices requires assessments. The aim of this study was to evaluate the validity of Fitbit One step counts (Fitbit Inc., San Francisco, CA, USA) against Actigraph wActisleep-BT step counts (ActiGraph, LLC, Pensacola, FL, USA) for measuring habitual physical activity among children.DesignThe study was implemented as a cross-sectional experimental design in which participants carried two waist-worn activity monitors for five consecutive days.MethodsThe participants were chosen with a purposive sampling from three fourth grade classes (9–10 year olds) in two comprehensive schools. Altogether, there were 34 participants in the study. From these, eight participants were excluded from the analysis due to erroneous data. Primary outcome measures for step counts were Fitbit One and Actigraph wActisleep-BT. The supporting outcome measures were based on activity diaries and initial information sheets. Classical Bland–Altman plots were used for reporting the results.ResultsThe average per-participant daily difference between the step counts from the two devices was 1937. The range was [116, 5052]. Fitbit One gave higher step counts for all but the least active participant. According to a Bland–Altman plot, the hourly step counts had a relative large mean bias across participants (161 step counts). The differences were partially explained by activity intensity: higher intensity denoted higher differences, and light intensity denoted lower differences.ConclusionsFitbit One step counts are comparable to Actigraph step counts in a sample of 9–10-year-old children engaged in habitual physical activity in sedentary and light physical activity intensities. However, in moderate-to-vigorous physical activity, Fitbit One gives higher step counts when compared to Actigraph.

AimTo describe the encounters with sexual and gender minority (SGM) youth in healthcare based on the existing research.BackgroundThe development of sexual orientation and gender identity can create challenges in an SGM youth’s life, and they may need support from health professionals. Heteronormativity has been recognised as a barrier to the identification of diversity in sexuality and gender, and no previous literature review has studied heteronormativity thoroughly.MethodsAn integrative review following Whittemore and Knafl was conducted. A literature search was systematically undertaken in six databases (PubMed/MEDLINE, CINAHL, Cochrane Library, PsycINFO, Eric, and Academic Search Premier). Finally, 18 research articles were included. Data were analysed deductively with the theoretical framework from Stevi Jackson’s (2006) article to understand the role of heteronormativity in the healthcare of SGM youth.FindingsThe encounters with SGM youth consisted of two simultaneous themes. Heteronormative care included three elements: (1) the effect of heteronormativity on health professionals’ competence to work with SGM youth, (2) false assumptions about SGM youth, and (3) the influence of heteronormativity on encounters with SGM youth. Diversity-affirming care included two elements: (4) the considerateness of health professionals towards SGM youth and (5) inclusive care of SGM youth.ConclusionThis review summarised how SGM youth were encountered in healthcare and how heteronormativity was affecting their healthcare. Furthermore, this review identified elements that supported diversity-affirming care. With diversity-affirming care, SGM youth may access the information and support they need from healthcare. Further research is needed about how diversity-affirming care can be applied to the healthcare of SGM youth and how elements of heteronormative care are occurring globally in the healthcare of SGM youth. The perceptions of transgender and other gender minority youth were under-represented in the studies and research needs to focus more on how they are encountered in healthcare.
