Electrographic indices in migraine patients: A systematic review and meta-analysis.

BACKGROUND AND AIM: Migraine patients can exhibit autonomic dysregulation, in turn leading to cardiac conduction and repolarization abnormalities. This systematic review and meta-analysis evaluated the electrocardiographic changes in migraineurs. METHOD: PubMed and Embase databases were searched for human studies using the search terms 'migraine' and 'electrocardiogram' until 15th December 2018, identifying 108 and 131 studies. RESULTS: Thirteen studies involving 667 migraineurs and 208 normal subjects included (mean age=30.7, total male percentage=19.8%) were included. A longer mean QTc interval (standard mean difference=7.89, 95% confidence interval=[3.29, 12.49], p=0.0008) and higher frequency of QTc prolongation (risk ratio [RR]=6.23, [2.86-13.58], p<0.00001), but no difference in PR-interval (SMD=4.33, [-3.90-12.56], p=0.30) were observed during migraine attacks compared to pain-free periods. P-wave dispersion was higher in migraine patients compared to controls (mean difference=3.62, [1.03-6.21], p=0.006). RR-interval were statistically indistinguishable between migraine patients and controls (SMD=0.08, [-0.65-0.81], p=0.83), or between migraineurs with and without aura (SMD=-0.03, [-0.44-0.38], p=0.89). Deep breathing ratio was significantly lower in migraineurs compared to controls (SMD=-0.27, 95% CI=[-0.46, -0.08], p=0.006) but similar between migraineurs with and without aura (SMD=-0.04, [-0.27-0.19], p=0.74). No significant difference in Valsalva ratio is found between migraineurs and controls (SMD=0.10, [-0.32-0.53], p=0.63) or between migraineurs with and without aura (SMD=-0.17, [-0.40-0.06], p=0.14). Root mean square of successive differences (RMSSD) (SMD=-0.07, [-1.10-0.95], p=0.89) and standard deviation of NN intervals (SDNN) (SMD=-0.10, [-0.61-0.41], p=0.71) did not significantly differ between migraine patients and controls. CONCLUSION: Electrocardiographic alterations are observed in migraine patients compared to controls, especially during migraine attacks.

Understanding Sociobehavioral Mitigators of Depressive Symptoms among U.S. Young Adults.

This study drew upon an ecological system framework to examine a model focusing on the interrelationship among depressive symptoms, sense of mastery, moderate-to-vigorous physical activity (MVPA), religiosity, and relations with parents and romantic partners among U.S. young adults aged 24 to 34. Cross-sectional data from the National Longitudinal Study of Adolescent Health (N = 4,982), obtained in 2008 and 2009, were analyzed using structural equation modeling techniques. The associations of MVPA, relations with parents, and relations with romantic partner to depressive symptoms were mediated through mastery. Relations with one's romantic partner were a stronger predictor of depressive symptoms than relations with parents, while the influence of religiosity on relations with romantic partner was largely mediated by relations with parents. The results highlight the sociobehavioral buffers of depressive symptoms that are peculiar to young adulthood. Further intervention research in preventing and treating depressive symptoms should consider incorporating the sociobehavioral factors that are tailored to the specific age group.

Go ta catch 'em al or not enough time: Users motivations for playing Pokémon Go™ and non-users' reasons for not installing.

Urban exergames are played in the real-world environment using built-in mobile phone sensors. The influence of Pokémon Go on physical activity and sitting time has been examined previously, however limited research has explored motivations for using the application. Thus, the aim of this study was to explore Pokémon Go users' motivations for using the application, exusers' reasons for abandoning the game and non-users' reasons for not installing. After institutional ethical approval, the 'Physical Activity and Pokémon Go' questionnaire was developed using QualtricsTM and distributed using social media soon after launch in the United Kingdom (baseline). At baseline a total of 461 participants (n=193 male, n=265 female, n=3 transgender) who were predominantly white (n=420) and did not self-report a disability (n=443) completed the questionnaire. Users' (n=236) were questioned on their motivations for using Pokémon Go and non-users' provided reasons for not installing. At 3 months a total of 127 participants (n=23 users) completed the questionnaire again and all qualitative data was thematically analyzed. The most commonly reported reason for using Pokémon Go was 'to have fun' which was 86% and 83% at baseline and 3 months respectively. The second most frequent reason at baseline was 'friends were using it' (58%) and at 3 months was 'to be outside' (48%). The least common motivation for using Pokémon Go at both baseline and 3 months was 'to meet new people' (8% and 0% respectively). At baseline, social motives and competition were two general themes which encapsulated Pokémon Go users' motivation for using the application. There were two general themes reported by Pokémon Go users' as to why they did not think they would use the application in the future. These were application related factors and factors unrelated to Pokémon Go. Non-users reported a range of reasons for not using Pokémon Go, including lack of interest and a lack of time. Safety concerns and risk of adverse events were reported by both users and non-users. This is the first study to thematically analyze motives for using Pokémon Go in which the findings are: 1) future smartphone applications aiming to increase physical activity must ensure that objectives evolve to maintain initial interest and motivation to engage with applications; 2) game developers must consider the required phone storage and capability which could be a barrier to downloading; and 3) concerns of using the application including the safety of users and those around them.

Smart technology for healthcare: Exploring the antecedents of adoption intention of healthcare wearable technology.

Technological advancement and personalized health information has led to an increase in people using and responding to wearable technology in the last decade. These changes are often perceived to be beneficial, providing greater information and insights about health for users, organizations and healthcare and government. However, to date, understanding the antecedents of its adoption is limited. Seeking to address this gap, this cross-sectional study examined what factors influence users' adoption intention of healthcare wearable technology. We used self-administrated online survey to explore adoption intentions of healthcare wearable devices in 171 adults residing in Hong Kong. We analyzed the data by Partial least squares - structural equation modelling (PLS-SEM). The results reveal that perceived convenience and perceived irreplaceability are key predictors of perceived usefulness, which in turn strengthens users' adoption intention. Additionally, the results also reveal that health belief is one of the key predictors of adoption intention. This paper contributes to the extant literature by providing understanding of how to strengthen users' intention to adopt healthcare wearable technology. This includes the strengthening of perceived convenience and perceived irreplaceability to enhance the perceived usefulness, incorporating the extensive communication in the area of healthcare messages, which is useful in strengthening consumers' adoption intention in healthcare wearable technology.

Examining Consumers' Adoption of Wearable Healthcare Technology: The Role of Health Attributes.

With the advancement of information technology, wearable healthcare technology has emerged as one of the promising technologies to improve the wellbeing of individuals. However, the adoption of wearable healthcare technology has lagged when compared to other well-established durable technology products, such as smartphones and tablets, because of the inadequate knowledge of the antecedents of adoption intention. The aim of this paper is to address an identified gap in the literature by empirically testing a theoretical model for examining the impact of consumers' health beliefs, health information accuracy, and the privacy protection of wearable healthcare technology on perceived usefulness. Importantly, this study also examines the influences of perceived usefulness, consumer innovativeness, and reference group influence on the adoption intention of wearable healthcare technology. The model seeks to enhance understanding of the influential factors in adopting wearable healthcare technology. Finally, suggestions for future research for the empirical investigation of the model are provided.

The reasons of dropout of sport in Hong Kong school athletes.

Dropout of sport is an issue in sport and public health domains. The aim of this study was to identify the potential dropout reasons of school athletes and to examine if their perception of dropout was affected by the previous dropout experience. There were 50 subjects who were divided into two groups based on their previous dropout experience (Dropout Group=22, No Dropout Group=28). They filled a questionnaire about potential dropout reasons of the current sport. Coach and teammates were two predominated reasons of dropout; Influence of parent and training seemed to affect the termination of the sport to a lesser extent. Moreover, the perception of social value and lost focus were significantly different between two groups. Character of coach and teammates affect the engagement of training in school athletes. However, the parental influence had less influence than expected. Training intensity played little role as the dropout reason. Previous experience of dropout had an impact of potential dropout reasons on their current sport training.

The Effectiveness of Health Literacy Oriented Programs on Physical Activity Behaviour in Middle Aged and Older Adults with Type 2 Diabetes: A Systematic Review.

Health literacy is the first step to self-management of type II diabetes mellitus, of which physical activity is the least compliant behavior. However, no reviews have summarized the effect and the process of interventions of health literacy oriented programs on physical activity behavior among middle aged and older adults with type II diabetes mellitus. This article is the first to examine the effectiveness of health literacy oriented programs on physical activity behavior among middle aged and older adults with type II diabetes mellitus. This systematic review extracted articles from nine electronic databases between 1990 and 2013. Six interventional studies were extracted and reported in accordance with the guidance of Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Findings demonstrated that health literacy oriented programs increased the frequency and duration of physical activity among patients with high health literacy. Although some studies effectively improved the health literacy of physical activity, gap in literature remains open for the indistinct and unreliable measurement of physical activity within self-management programs of type II diabetes mellitus, and the questionable cross-culture generalizability of findings. Further studies with well-knit theory-based intervention with respect to patients' cultural background, duration of intervention and objective measurements are encouraged to elucidate the relationship between health literacy oriented programs and physical activity behavior.
