UNASSIGNED: Hedonic smartphone use has been associated with dependence and addiction studied under the umbrella term Problematic Smartphone Use (PSU). Research usually explores total screen time as an index of PSU. A few studies suggest that exercise is inversely related to smartphone use time. However, it is unknown which primary characteristics of exercise behavior are related to more moderate smarthone use. Furthermore, the purpose of smartphone use, such as hedonic use associated with PSU versus utilitarian use, was not tested in the sports and exercise contexts. Hedonic use generally means playing with the smartphone for joy, distraction, and satisfaction. Utilitarian use implies practical and valuable use. There is a conjecture that sports involvement may foster utilitarian use through increased involvement in sports-related information-seeking, goal-setting, and self-monitoring.
UNASSIGNED: Therefore, we examined whether weekly exercise frequency, workout duration, and perceived exercise intensity relate to total daily smarthone and hedonic use and whether this relationship is mediated by sports-related utilitarian device use. We tested regularly exercising adults (n = 360, 132 males, M age = 39.0 ± 9.8, M weekly exercise = 5.8 ± 1.9) who volunteered for this study and provided demographic information about their exercise habits and smartphone use.
UNASSIGNED: The results revealed that all exercise parameters mediated the total daily smartphone use, with perceived exercise intensity being a negative predictor. Further, exercise frequency and duration (but not intensity) positively predicted sports-related smartphone use, which inversely predicted hedonic use.
UNASSIGNED: These results suggest that exercise parameters directly relate to daily smartphone use, which completely mediates hedonic use. These findings may partially account for the frequently reported inverse relationship between regular exercise and PSU by suggesting that the connection is mediated via sports-related smartphone use.

Technological advancements have expanded the range of methods for capturing human body motion, including solutions involving inertial sensors (IMUs) and optical alternatives. However, the rising complexity and costs associated with commercial solutions have prompted the exploration of more cost-effective alternatives. This paper presents a markerless optical motion capture system using a RealSense depth camera and intelligent computer vision algorithms. It facilitates precise posture assessment, the real-time calculation of joint angles, and acquisition of subject-specific anthropometric data for gait analysis. The proposed system stands out for its simplicity and affordability in comparison to complex commercial solutions. The gathered data are stored in comma-separated value (CSV) files, simplifying subsequent analysis and data mining. Preliminary tests, conducted in controlled laboratory environments and employing a commercial MEMS-IMU system as a reference, revealed a maximum relative error of 7.6% in anthropometric measurements, with a maximum absolute error of 4.67 cm at average height. Stride length measurements showed a maximum relative error of 11.2%. Static joint angle tests had a maximum average error of 10.2%, while dynamic joint angle tests showed a maximum average error of 9.06%. The proposed optical system offers sufficient accuracy for potential application in areas such as rehabilitation, sports analysis, and entertainment.

UNASSIGNED: Entertainment media content is often mentioned as one of the roots of children\'s unhealthy food consumption. This might be due to the high quantity of unhealthy foods presented in children\'s media environments. However, less is known about the role of the centrality of food placement, that is, whether foods are interacted with, consumed, verbally mentioned, or appear unobtrusively. We also lack longitudinal research measuring both children\'s unhealthy and healthy food consumption behaviors as outcomes.
UNASSIGNED: The aim is to connect content analytical data based on children\'s actual media diet with panel data in order to explain children\'s food preferences. Moreover, this study not only focuses on the amount of healthy and unhealthy foods children are exposed to, but also on how these foods are presented (ie, centrally or not). Furthermore, we looked at the question of how parental coviewing can diminish (or enhance) the effects of unhealthy (or healthy) food depictions, and we measured healthy and unhealthy consumption as dependent variables.
UNASSIGNED: We conducted a 2-wave panel study with children and one of their parents (of 2250 parents contacted, 829 responded, for a response rate of 36.84%; 648 valid cases, ie, parent-child pairs, were used for analysis), with 6 months between the 2 panel waves. We linked the 2-wave panel data for the children and their parents to content analytical data for movies (n=113) and TV series (n=134; 3 randomly chosen episodes per TV series were used) that children were exposed to over the course of 6 months.
UNASSIGNED: There was no significant relationship between exposure to unhealthy food presentation and unhealthy (b=0.008; P=.07) or healthy (b=-0.003; P=.57) food consumption over time. Also, healthy food presentation was unrelated to unhealthy (b=0.009; P=.18) or healthy (b=0.000; P=.99) food consumption over time. However, there was a significant, positive interaction between unhealthy food presentation and presentation centrality on unhealthy food consumption (b=0.000; P=.03), suggesting that the effects of unhealthy food presentation rise with increasing levels of centrality. There was no interaction between unhealthy food presentation and presentation centrality on the consumption of healthy foods (b=0.000; P=.10). Also, exposure to healthy food presentation interacted with centrality (b=-0.001; P=.003). That is, when a healthy product was presented at maximum centrality, it led to less unhealthy food consumption in children. Coviewing did not interact with exposure to unhealthy foods when explaining unhealthy (b=0.003; P=.08) or healthy (b=-0.001; P=.70) food consumption.
UNASSIGNED: We conclude that simply presenting more healthy foods is not sufficient to combat children\'s unhealthy food preferences. Further regulations may be necessary with respect to representations of unhealthy foods in children\'s media.

Participation in arts, culture, and entertainment (PACE) activities may promote adolescent wellbeing. However, little is known about how such activities cluster together, and previous research has used small samples, cross-sectional designs, focused on single activities, and/or has not considered the influence of socio-demographic factors on participation. Using latent class analysis, the aims of this study were to establish: (i) classes of adolescent PACE activities; (ii) associations between socio-demographic characteristics and PACE classification; and, (iii) whether PACE classification predicts later wellbeing. Longitudinal data from the #BeeWell study (N = 18,224 adolescents; mean age at T1 = 12 years 7 months (±3.56 months); 50.54% female) were analyzed. Four latent classes were established: the \'Dynamic Doers\' (high, wide-ranging participation; 11.87%); the \'Mind and Body Crew\' (reading, arts, videogames, sports/exercise; 39.81%); the \'Game and Gain Squad\' (videogames and sports/exercise; 29.05%); and the \'Activity Free Adolescents\' (uniformly low participation; 19.27%). Associations between socio-demographic characteristics and PACE classification were observed (e.g., socio-economic disadvantage increased the likelihood of Activity Free Adolescents classification, compared to Game and Gain Squad classification). Finally, PACE classification predicted later wellbeing (e.g., Dynamic Doers reported significantly higher wellbeing than Activity Free Adolescents). These findings are discussed in relation to the need to improve accessibility and appeal of arts, culture, and entertainment provision for adolescents as a means to optimize their wellbeing.

Misinformation remained a critical consideration during the COVID-19 that further cultivated fears leading to strong unrest among the public globally. This study clarifies certain misconceptions related to the pandemic by investigating whether factors such as altruism, entertainment, information-sharing, information-seeking, comprehensibility have impact on COVID-19 misinformation acceptance and sharing it in the UAE culture, with gender as a moderating factor. An online survey (google.com) was used, with a sample of 200 university students, and analyzed using PLS-SEM software to determine the effects of constructed factors. The findings indicated that entertainment, information-sharing, and information-seeking factors have impact on sharing COVID-19 misinformation, while comprehensibility has impact on acceptance of misinformation. Interestingly, gender was found to have no impact on all the constructed factors, suggesting that other moderating factors (e.g., age) need to be considered in future research. Generally, online users need to learn how to verify online information that they receive/share on other social media, especially regarding health concern.

Few studies have analyzed the acceptance of home/community-based medical and elderly care services in China. Therefore, we conducted a cross-sectional study to describe the acceptance of five services among people aged ≥ 45 years in the China mainland, and their influencing factors. The data were obtained from the database China Health and Retirement Longitudinal Study 2018. For each service, a binary logistics regression was adopted. A total of 9719 people were included, of whom 20.12% received services. The numbers of recipients (acceptance rates) of the five services, namely, comprehensive aged care services, regular physical examinations, onsite visits, health management, and entertainment, were 107 (1.10%), 1640 (16.87%), 323 (3.32%), 156 (1.61%), and 245 (2.52%), respectively. About 4% of people had received two or more services. The elderly aged 65-74 and those who were satisfied with the local medical services had higher acceptance of services. Urban hukou having health insurance, two or more chronic diseases, provincial economic welfare, and social welfare were positively associated with the acceptance of regular physical examination services. It is suggested that the government should gradually improve satisfaction with local medical services, and pay more attention to the needs of elderly people aged 65-74 for all kinds of home/community-based medical and elderly care services.

Undulatory locomotion relies on the propagation of a wave of excitation in the spinal cord leading to consequential activation of segmental skeletal muscles along the body. Although this process relies on self-generated oscillations of motor circuits in the spinal cord, mechanosensory feedback is crucial to entrain the underlying oscillatory activity and thereby, to enhance movement power and speed. This effect is achieved through directional projections of mechanosensory neurons either sensing stretching or compression of the trunk along the rostrocaudal axis. Different mechanosensory feedback pathways act in concert to shorten and fasten the excitatory wave propagating along the body. While inhibitory mechanosensory cells feedback inhibition on excitatory premotor interneurons and motor neurons, excitatory mechanosensory cells feedforward excitation to premotor excitatory interneurons. Together, diverse mechanosensory cells coordinate the activity of skeletal muscles controlling the head and tail to optimize speed and stabilize balance during fast locomotion.

A social pension, regarded as a reliable source of income, has the potential to significantly influence the overall wellbeing of vulnerable older adults. This study aimed to extend the understanding of the effects of social pension expansion beyond its economic impacts to encompass recipients\' health status. Using three-wave data from a representative sample of older adults, we employed a quasi-experimental assessment model to evaluate the impact of a recent social pension expansion in Hong Kong on health-related consumption and health outcomes among older adults. The results of the triple difference estimations revealed that an increased social pension significantly enhanced older people\'s engagement in entertainment activities, utilization of healthcare services, and expenditures on preventive health products. Furthermore, the increased social pension was found to have a significant positive effect on mitigating poor self-rated health and poor sleep quality. However, it did not have a significant impact on the prevalence of depression. These findings suggest that social pension expansion should be coordinated with other policy initiatives to comprehensively improve the physical and mental health of older adults.

In an effort to arrest the spread of coronavirus (COVID-19) infection, a nationwide lockdown was declared in India in March 2020. To assess how personal built environments affected the citizens in the first few weeks, an explorative online survey was conducted, eliciting responses about work habits before the lockdown, psychological wellbeing, time spent in various activities, characteristics of those who worked from home, and food and sleep patterns. We received 121 (76 male and 45 female) responses with an average age of 35.5 years [max: 70 years, min: 18 years, standard deviation (SD): 12.9 years]. The major difference caused by the lockdown was a reduction in the time taken and distance travelled of the commute to workplaces, which was an average of 30 minutes and 9.5 km, respectively. In terms of diet, subjects who were vegetarian did not experience any difference, unlike those who were non-vegetarians (p < 0.05). The results show an association of the dependent variable of \'feeling in general\' with predictor variables of \'energy, pep, vitality\' and \'feel healthy to work\' during the pandemic, whereas the predictor variables of \'energy, pep, vitality\', \'happy and satisfied personal life\', \'feel healthy to work\' show an association with the dependent variable of \'feeling in general\' before the lockdown with a significance of p < 0.02 and R2 = 0.51 and R2 = 0.60, respectively. Among those who worked from home in constrained environments, people found spaces and seemed to adapt reasonably well to the built environment with employees showing a preference for working from bedrooms and students for working from \'sit-out\' (outside) spaces (p < 0.05). There was no change in the quality or quantity of sleep during the lockdown. This study in the early weeks of the lockdown documents the way in which individuals lived through it in terms of the built environment at home.

UNASSIGNED: Fictional portrayals of autism play a role in raising awareness, shaping knowledge, and influencing attitudes toward autism. However, the accuracy of these portrayals is a topic of debate. Limited research has been conducted with the autism community regarding their perceptions of fictional portrayals of autism. This study aimed to explore autistic people\'s perceptions of the accuracy, educational benefits, and impact of Atypical, a Netflix comedy drama series focused on the experiences of an autistic protagonist.
UNASSIGNED: Participants were 77 members of the autism community (autistic N = 65, parent/partner N = 12), recruited via social media. Participants completed a cross-sectional predominantly qualitative survey. We undertook descriptive statistical analyses on the quantitative data and used a reflexive thematic analysis approach to analyze the qualitative data.
UNASSIGNED: The majority of participants described Sam\'s portrayal as accurate, emphasizing that it was accurate as one example of autism. Family members appeared more likely to perceive Atypical as having informative benefit and being likely to improve attitudes toward autism than were autistic people. The primary concerns identified were the stereotypical representation of a popular media image of autism, the lack of diversity, and the depiction of autism as a burden or challenge for the protagonist and his family.
UNASSIGNED: This study builds on previous research on the portrayal of autism in entertainment media by investigating the perception of the autism community regarding one such fictional portrayal. It identifies that for entertainment media to better represent the lived experience of autistic people and improve community understanding of autism, there is a need for increased diversity of portrayals and for the involvement of autistic people in the development and production process.
UNASSIGNED: Portrayals of autism on television and in movies may increase autism awareness and knowledge and improve attitudes toward autistic people. However, they may also reinforce autism stereotypes and negative attitudes. Research shows that there are an increasing number of autistic characters in movies and television stories. Some studies find that these portrayals are largely accurate, others that they are misleading, and some that they are mixed. What has not been studied is what members of the autism community think about the accuracy, value, and likely impacts of these fictional portrayals.
UNASSIGNED: The purpose of this study was to explore the perceptions of members of the autism community—autistic people and their families—about the Netflix television series Atypical and its autistic main character Sam Gardner.
UNASSIGNED: The researchers recruited 77 people who had watched Atypical: 65 autistic people, 10 parents of autistic children, and 2 partners of autistic adults. Participants were recruited through social media and completed an anonymous online survey. Questions addressed their perceptions of the accuracy of the portrayal of Sam as an autistic person, and whether they thought the show would improve autism knowledge and attitudes.
UNASSIGNED: The majority of participants thought that Sam\'s portrayal of autism within Atypical was accurate and that it would have some degree of educational benefit for non-autistic people. Family members appeared more likely than autistic people to think that Sam\'s portrayal was accurate, to believe that the show had educational benefit, and to agree that the show was likely to lead to more positive attitudes about autism. Participants expressed concern that Sam\'s portrayal was a stereotypical male representation of autism that was not representative of the broader autistic community and that the show presented a deficit-focused view of autism.
UNASSIGNED: This study provides valuable information regarding the autism community\'s perceptions of the accuracy of the portrayals of autism, the potential educational benefit, and the likely influence on attitudes. It identifies that for entertainment media to better represent the lived experience of autistic people and improve community understanding of autism, there is a need for increased diversity of portrayals.
UNASSIGNED: The main weaknesses of the study are the overrepresentation of females (64%), the focus on a single television series with a male protagonist, and the limited detail on the participants\' life experiences due to the anonymous nature of the study.
UNASSIGNED: This study should assist in advocacy with the producers of entertainment media, enabling them to hear the voices of the autism community and take on board their suggestions for more inclusive and representative portrayals of autism. Doing so has the potential to raise awareness, acceptance, and appreciation of autistic people in the broader community.
