Vaccination has emerged as the most cost-effective public health strategy for maintaining population health, with various social and economic benefits. These vaccines, however, cannot be effective without widespread acceptance. The present study examines the effect of media attention on COVID-19 vaccine hesitancy by incorporating fear of COVID-19 as a mediator, whereas trust in leadership served as a moderator. An analytical cross-sectional study is performed among rural folks in the Wassa Amenfi Central of Ghana. Using a questionnaire survey, we were able to collect 3079 valid responses. The Smart PLS was used to estimate the relationship among the variables. The results revealed that media attention had a significant influence on vaccine hesitancy. Furthermore, the results showed that fear of COVID-19 played a significant mediating role in the relationship between media and vaccine hesitancy. However, trust in leadership had an insignificant moderating relationship on the fear of COVID-19 and vaccine hesitancy. The study suggests that the health management team can reduce vaccine hesitancy if they focus on lessening the negative impact of media and other antecedents like fear on trust in leadership., Competing Interests: The authors have declared that no competing interests exist.

Since 2012, the citizen science project 'Mückenatlas' has been supplementing the German mosquito monitoring programme with over 28,000 submissions of physical insect samples. As the factors triggering people to catch mosquitoes for science are still unknown, we analysed the influence of mass media reports on mosquito submission numbers. Based on a theoretical framework of how mass media affect citizen responsiveness, we identified five possible influencing factors related to citizen science: (i) project awareness and knowledge, (ii) attention (economy), (iii) individual characteristics of citizen scientists and targeted communication, (iv) spatial differences and varying affectedness, and (v) media landscape. Hypotheses based on these influencing factors were quantitatively and qualitatively tested with two datasets: clipping data of mass media reports (online, television, radio and print) referring to or focussing on the 'Mückenatlas', and corresponding data of 'Mückenatlas' submissions between 2014 and 2017. In general, the number of media reports positively affected the number of mosquito submissions on a temporal and spatial scale, i.e. many media reports provoke many mosquito submissions. We found that an already heightened public and media awareness of mosquito-relevant topics combined with a direct call-to-action in a media report title led to a maximum participation. Differences on federal state level, however, suggest that factors additional to quantitative media coverage trigger participation in the 'Mückenatlas', in particular the mosquito affectedness of the resident population. Lastly, media types appear to differ in their effects on the number of submissions. Our results show under which circumstances the media presence of the 'Mückenatlas' is most effective in activating people to submit mosquito samples, and thus provide advice for designing communication strategies for citizen science projects., Competing Interests: The authors have declared that no competing interests exist.

Social media has surrounded every area of life, and social media platforms have become indispensable for today's communication. Many journals use social media actively to promote and disseminate new articles. Its use to share the articles contributes many benefits, such as reaching more people and spreading information faster. However, there is no consensus in the studies that to evaluate between tweeted and non-tweeted papers regarding their citation numbers. Therefore, it was aimed to show the effect of social media on the citations of articles in the top ten communication-based journals. For this purpose, this work evaluated original articles published in the top 10 communication journals in 2018. The top 10 communication-based journals were chosen based on SCImago Journal & Country Rank (cited in 2019). Afterward, it was recorded the traditional citation numbers (Google Scholar and Thompson-Reuters Web of Science) and social media exposure of the articles in January 2021 (nearly three years after the articles' publication date). It was assumed that this period would allow the impact of the published articles (the citations and Twitter mentions) to be fully observed. Based on this assessment, a positive correlation between exposure to social media and article citations was observed in this study., Competing Interests: The authors have declared that no competing interests exist.

Background: The purpose of this study was to examine the association between electronic media use, including use of social media and gaming, and symptoms of depression, and whether gender or having friends moderated these associations., Methods: This study was based on self-reported cross-sectional data from the Ungdata survey, conducted in 2018 by the Norwegian Social Research (NOVA) Institute in cooperation with seven regional drug and alcohol competence centres. The target group comprised 12,353 15-16 years old adolescents. Binominal logistic regression was used to analyse the association between electronic media use and symptoms of depression., Results: The odds of having symptoms of depression were higher for those who used social media more than 3 hours per day (OR: 1.60, 95% CI: 1.43-1.80), compared to those who used social media 3 hours or less per day. Additionally, the odds of having symptoms of depression was higher for those who used more than 3 hours on gaming per day (OR: 1.57, 95% CI: 1.36-1.80), compared to those who used 3 hours and less on gaming per day after adjustment for potential confounders. There were no interaction effects between social media and gaming use with symptoms of depression. Neither were the associations between social media use and gaming with symptoms of depression moderated by gender or having friends., Conclusions: The odds of having symptoms of depression were significantly higher for adolescents with a more frequent use of electronic media., Competing Interests: The authors have declared that no competing interests exist.

Coronavirus has spread worldwide with over 140 million cases and resulting in more than 3 million deaths between November 2019 to April 2021, threatening the socio-economic and psychosocial stability of many families and communities. There has been limited research to understand the consequences of COVID-19 on vulnerable populations in West Africa, and whether such consequences differ by countries' previous experience with Ebola. Using a media analysis of leading online news sources, this study identified the populations particularly vulnerable to the threats of the COVID-19 pandemic, described the consequences of COVID-19 experienced by these populations, and reported on the solutions to address them. All articles from the selected news sources published between January 1 and June 30, 2020 on 6 West African countries were imported into Dedoose. A total of 4,388 news articles were coded for excerpts on vulnerable populations, only 285 excerpts of which mentioned the existing effects of COVID-19 on vulnerable populations or implemented solutions. News articles from countries with past experience with Ebola were more likely to mention the pandemic's effects on vulnerable populations, especially on incarcerated people. Vulnerable groups were reported to have experienced a range of effects including economic disruptions, heightened domestic and sexual abuse, arbitrary arrests, health care inaccessibility, and educational challenges throughout the pandemic. With implications for the achievement of the Sustainable Development Goals (SDG) for 2030 in West Africa, these countries should consider and focus more strategic efforts on vulnerable populations to overcome their fight against the COVID-19 pandemic and to achieve the SDG for 2030., Competing Interests: The authors have declared that no competing interests exist.

Purpose: To describe the use of tramadol and other analgesics in Denmark focusing on the impact of media attention (June and December 2017) and regulatory actions (September 2017 and January 2018) on the use of tramadol., Methods: Using nationwide registries, we identified all adults who filled a prescription for tramadol and other analgesics from 2014 to 2019. We described incidence rates, prevalence proportions, and total use of tramadol and other analgesics over time. We also described switching between analgesics, treatment duration, skewness in drug use, and doctor-shopping., Results: From early 2017 until the end of 2019, total tramadol use decreased markedly while the use of morphine and oxycodone decreased slightly. The quarterly prevalence of tramadol use decreased from 32/1000 individuals in 2014 to 18/1000 at the end of 2019, dropping mainly at the time of media attention. Concomitantly, the quarterly prevalence increased for oxycodone (from 5.1 to 8.2) and morphine (from 8.5 to 9.8), mainly due to more short-term and sporadic users, and decreased for codeine (14 to 9.6). From 2014 to mid-2017, the incidence of tramadol use was stable (around 2.2/1000 person-months) but dropped in June 2017 to 1.7/1000, coinciding with the media attention. The incidence of tramadol use continued to decrease (to 1.1/1000 at the end of 2019)., Conclusion: We identified a decline in tramadol use coinciding with the media attention in 2017 and continuing during regulatory actions. There was generally no evidence of unintended effects on the utilization of opioids related to the media attention and regulatory actions.

False news stories cause welfare losses and fatal health consequences. To limit its dissemination, it is essential to know what determines the ability to distinguish between true and false news stories. In our experimental study, we present subjects corona-related stories taken from the media from various categories (e.g. social isolation, economic consequences, direct health consequences, and strong exaggeration). The subject's task is to evaluate the stories as true or false. Besides students with and without healthcare background, we recruit healthcare professionals to increase the external validity of our study. Our main findings are: (i) Healthcare professionals perform similar to students in correctly distinguishing between true and false news stories. (ii) The propensity to engage in analytical thinking and actively open-minded thinking is positively associated with the ability to distinguish between true and false. (iii) We find that the residence of the subjects (East- or West-Germany) plays only a minor role. (iv) If news stories are in line with existing narratives, subjects tend to think that the stories are true., Competing Interests: The authors have declared that no competing interests exist.

Objective: Examine the association between news media use frequency during the COVID-19 pandemic and the scale of psychological distress in pregnant women, considering this distress known harmful effects on the fetus development., Method: Pregnant women living in Quebec province (N = 1014) have been recruited in April 2020 through social media, while a state of health emergency was declared. Participants were divided in 4 groups, according to self-reported frequency of news media consulting (little or none; one time a day; several times a day; constant). They filled measures of depressive symptoms, negative affects, post-traumatic stress symptoms and anxiety specific to COVID-19. Instrument scores were grouped under a unique factor of psychological distress., Results: An ANCOVA controlling for age, gestational age, education level, household annual revenue and a diagnosed mental disorder present at the time of participation in study shows that news media exposure frequency is significantly associated with psychological distress severity in pregnant women, during COVID-19 pandemic, F(3,998) = 27.02, p < 0.001, η2 partial = 0.08. Given the mean comparisons a posteriori , higher psychological distress rates are found as soon as news media exposure exceeds once a day (effect sizes between 0.38 and 0.81)., Conclusions: The more pregnant women report consulting the news media during the COVID-19 pandemic, the more likely they are to exhibit psychological distress. Results provide one of the first empirical supports to recommendations of World Health Organization, Canada government and psychiatric associations that encourage population to limit their news media consulting during the COVID-19 pandemic.

Internet use in the youth has increased manifold during the coronavirus disease 2019 (COVID-19) pandemic. Individuals with autism spectrum disorder (ASD) generally have a higher risk of problematic internet use. The aim of this study is to investigate the differences in internet and related digital media use between children with ASD and their typically developing counterparts during the COVID-19 pandemic. In this online survey in Japan conducted from April 30 to May 8, 2020, we analyzed digital media time of 84 children with ASD and 361 age- and gender-matched controls before and after school closure. Digital media use duration was significantly longer in the ASD group than in the control group before the pandemic. The increase of media use time was more prominent in the control group than in the ASD group. We observed excessive Internet use among children with ASD and without ASD, especially during the COVID-19 pandemic. It is necessary to establish strategies to prevent excessive internet use in not only children and adolescents with ASD but also without ASD in the post-pandemic world., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2020 Kawabe, Hosokawa, Nakachi, Yoshino, Horiuchi and Ueno.)

Technology, Entertainment, Design (TED) Talks have represented a broad source of health communication since 1984. However, to date, no studies exist on how this tool addresses the question of cancer. In this paper, we aim to illuminate two major issues: (1) Are TED Talks a good source for cancer communication? (2) How does the public respond to cancer-related TED Talk lectures? To this end, we searched for the keyword 'cancer' on the TED.com website in January 2018. All transcripts were obtained along with related information such as numbers of views, like and dislike rates. We also analysed a sample of 938 comments, corresponding to the 10 most relevant (if existing) regarding each video on TED.com and YouTube platforms. From the 49 videos pertaining to cancer, 33 were scientific-related, whereas 11 focused on speakers' personal experiences. Only three videos approached prevention themes of major relevance for cancer communication to broad audiences. Instead, they brought more therapy (16) and diagnosis (12) issues and often promoted exaggerated extrapolations of research results (20). Scientific lectures also made frequent use of a 'bad vs. good' duality discourse by criticizing current science/policies and then offering a solution/hope. Regarding the public response, non-scientific lectures had more negative votes than scientific counterparts. Moreover, the audience exhibited two major motivations to provide a comment: to judge the lectures and to share personal stories. We believe that our observations are of considerable relevance for helping in enhancing this tool as a substantial cancer communication source.

State-sponsored disinformation campaigns increasingly use anti-vaccine comments to not only undermine public health but to also reduce confidence and participation in a democratic society. Despite these dangers, research has not fully explored whether anti-vaccine comments can achieve these effects. To address this gap, an online survey experiment was conducted using a national sample of 1010 U.S. adults. Participants read a mainstream news article discussing the flu vaccine that included random variations of user comments adapted from a documented state-sponsored disinformation campaign. While exposure to anti-vaccine comments did not affect participants' views of vaccines or their willingness to discuss vaccines, participants holding pro-vaccine views reported lower confidence in news organizations and viewed the journalist who authored their article as less credible. These results suggest that anti-vaccine comments may produce effects that align with the goals of state-sponsored disinformation campaigns.

Korean adolescents at high risk for smoking are less exposed to anti-tobacco media messages. This study examines whether school-based smoking prevention education is related to media exposure and whether it can contribute to reducing the gap in exposure to anti-tobacco media messages between smoking vulnerable and non-vulnerable groups. A nationally representative dataset, the 2018 Korea youth risk behavior web-based survey, comprising 59,410 students from grades 7-12, was analyzed. Logistic regression models were designed to evaluate the association between school-based smoking prevention education and media messages exposure. Within-group differences in exposure levels based on sociodemographic characteristics were compared depending on participation or nonparticipation in school-based smoking prevention education. Experience of smoking prevention education within a year was significantly associated with exposure to anti-tobacco media messages. Among Korean adolescents who participated in smoking prevention education compared to those who did not, the media messages exposure rate was more than 20% higher, and the exposure gap within the subgroups by sociodemographic characteristics was narrower. Participation in school-based smoking prevention education was significantly related to media messages exposure. This relationship can be used to improve the overall media messages exposure rate and to reduce the differences in exposure rate based on sociodemographic traits.

With the development of digital technology, media multitasking behaviour, which is using two or more media simultaneously, has become more commonplace. There are two opposing hypotheses of media multitasking with regard to its impact on attention. One hypothesis claims that media multitasking can strengthen attention control, and the other claims heavy media multitaskers are less able to focus on relevant tasks in the presence of distractors. A total of 103 healthy subjects took part in this study. We measured the Media Multitasking Index (MMI) and subjects performed the continuous performance test. Resting state and oddball task functional MRI were conducted to analyse functional connectivity in the dorsal attention network, and the degree centrality (DC) was calculated using graph theory analysis. We found that the DCs in the dorsal attention network were higher during resting state than during the oddball task. Furthermore, the DCs during the task were positively correlated with the MMI. These results indicated that the DC reduction from resting state to the oddball task in high media multitaskers was attenuated compared with low media multitaskers. This study not only reveals more about the neurophysiology of media multitasking, but could also indicate brain biomarkers of media multitasking behaviour.

Growing concerns about intensive information and communication technology (ICT) use led to abundant research on its debilitating effects on employees' abilities to meet family demands. Drawing on the stressor-strain model, we conducted a daily diary study to investigate how different types of daily ICT demands experienced during work hours and after work influence work-family conflict (WFC) in the evening. We collected data from 98 full-time employees (793 day-level observations) for 10 consecutive workdays to understand employees' work-nonwork interface experiences, namely, negative spillover and role conflict. First, we examined a multilevel mediation model to test the negative spillover effect of on-the-job ICT demands on WFC in the evening via negative affect (NA) at the end of the workday. Second, we investigated the effects of off-the-job ICT demands on WFC to provide evidence of role conflict in the nonwork domain. Further, we tested the protective role of boundary control in these phenomena. The multilevel analysis results revealed that different types of ICT demands experienced at work have idiosyncratic impacts on WFC. Also, while extended availability after work hours yields greater WFC, this link was weaker for the employees who perceive high boundary control., (© 2020 John Wiley & Sons, Ltd.)

During the Covid-19 pandemic, risk communication has often been ineffective, and from this perspective "fake news" has found fertile ground, both as a cause and a consequence of it. The aim of this study is to measure how much "fake news" and corresponding verified news have circulated in Italy in the period between 31 December 2019 and 30 April 2020, and to estimate the quality of informal and formal communication. We used the BuzzSumo application to gather the most shared links on the Internet related to the pandemic in Italy, using keywords chosen according to the most frequent "fake news" during that period. For each research we noted the numbers of "fake news" articles and science-based news articles, as well as the number of engagements. We reviewed 2102 articles. Links that contained fake news were shared 2,352,585 times, accounting for 23.1% of the total shares of all the articles reviewed. Our study throws light on the "fake news" phenomenon in the SARS-CoV-2 pandemic. A quantitative assessment is fundamental in order to understand the impact of false information and to define political and technical interventions in health communication. Starting from this evaluation, health literacy should be improved by means of specific interventions in order to improve informal and formal communication.

COVID-19 is lasting longer than expected, which has a huge impact on the economy and on personal life. Each country has a different response method, and the damage scale is also distinct. This study aims to find out how COVID-19-related news was handled in the domestic media to seek ways to minimize the pandemic. The paper focuses on the number of news features by period and by disaster and analyzes related words based on big data. The results of the analysis are as follows. First, in the initial response phase, keywords to identify accurate sources of actual broadcast contents, fake news, social networking service (SNS), etc. were also ranked in the top 20. Second, in the active response phase, when the number of confirmed persons and the government's countermeasures were announced, more than 100 COVID-19-related articles were issued, and the related words increased rapidly from the initial response stage. Therefore, the fact that COVID-19 has been expressed as a keyword indicates that our society is watching with great interest in the government's response to the disease.

Background and Objectives: Emotion regulation refers to the way individuals manage and regulate their own emotions in response to negative emotional experiences. This study investigated whether media multitasking serves as an avoidance coping strategy for managing emotionally stressful events. Design and Methods: Using a correlational design, 140 participants completed self-report measures of media multitasking and emotion regulation, and cognitive measures assessing attentional bias for emotionally negative stimuli. Results: Media multitasking was associated with difficulties in accepting emotional responses for participants who showed an attentional bias away from anxiety words, and for participants with poorer inhibitory control over such words. Further, there was a strong association between media multitasking and reduced interference from anxiety words for participants with stronger inhibitory control over such words in the emotional Stroop task. Conclusions: Results support the idea that media multitasking is linked to difficulty dealing with emotionally negative stimuli and serves as an avoidance coping strategy where one deliberately directs attention away from negative stimuli to prevent their further processing. The findings have real-life implications for managing anxiety and depression, as media multitasking may be used as a maladaptive coping strategy that further increases these negative moods.

Parental attitudes and behavior can impact infant media use, though all existing research examines this after the baby is born. However, many studies suggest that prenatal attitudes and behavior can influence parenting practices around many different types of parenting decisions. This study examines whether this extends to parenting practices surrounding media use during infancy. Participants consisted of 170 mothers who completed a number of questionnaires at two time points (prenatally and when infant was ∼16 months old). Results revealed that parents had many concerns about media before their child was born. More supportive prenatal attitudes regarding using media as a coping strategy was associated with higher levels of infant media use and technoference (i.e., when media interfere with the parent-child relationship). Additionally, prenatal media use by mothers was associated with higher levels of infant media use, but lower levels of technoference. Finally, prenatal depression was associated with higher technoference, while parental efficacy was associated with higher infant video chat. Implications of the study include discussion regarding media use at medical office prenatal visits and creating a family media plan before the birth of the child.

Research suggests that toddlers with regulation issues engage in significantly more media use than toddlers without regulation difficulties, and this may be due, in part, to parental strain associated with parenting a child who is difficult to regulate or soothe. The current study sought to determine if the observed relationship between parental strain and child media use in the context of regulation difficulties continues into the preschool years. Data from the 2016 ( N  = 6,976) and 2017 ( N  = 3,056) National Survey of Children's Health were used to test a structural equation model (SEM) examining the moderating effect of parenting strain on the relationship between child media use and child regulation after controlling for socioeconomic status (SES) and adverse childhood experiences. The SEM had reasonable model fit. The study did not find a moderating effect for parenting strain but did identify a small significant relationship between child media use and regulation after controlling for parenting strain and SES. Additionally, SES proved to be a strong moderator of regulation and child media use. These findings point to the possibility that the relationship between parental strain and child media use may be more directly related to perceived ability to calm their child identified in previous research rather than perception of child's difficulty. This study demonstrated that the negative link between child media use and regulation may persist into the preschool years. Limitations of the study include broad items used to assess time spent with media and limited depth of questions associated with regulation and parenting strain.

Although the American Academy of Pediatrics recommends not to heavily rely on screen media devices to regulate children's distress, many parents often resort to this regulatory strategy. However, little is known about the long-term implications of using this strategy for children's emotional functioning. To address this issue, this study examined the longitudinal links between the use of media to regulate distress and children's negative emotionality (NE) during toddlerhood, a period in which children strongly rely on external regulation. We also examined whether children with initially high NE were more sensitive to the effects of this regulatory strategy on subsequent NE. Participants were 207 mothers who completed questionnaires assessing child NE, use of media to regulate distress, child screen time, and demographic covariates at 2 time points: 18 months (T1) and 26 months (T2) of children's age. Use of media to regulate child distress at T1 did not directly predict child NE at T2, and vice versa. However, there was a significant interaction between child NE and use of media to regulate distress at T1 in predicting NE at T2. Simple slopes analysis indicated that maternal use of media to regulate distress was positively related to increases in children's NE, but only for children with initially low NE, and not for children with initially high NE. Our findings can inform family-based prevention initiatives that may be delivered in community pediatric settings, aiming at promoting thoughtful use of media in young children's everyday lives.

Limited research has examined bidirectional associations between modern media (e.g., smartphone, tablet) use and behavior in early childhood. This study aimed to test the hypotheses that, over 6 months, (H1) child externalizing behavior would predict later media use, mediated by parenting stress, and (H2) media use would predict later externalizing behavior. Participants included mothers and fathers from 183 heterosexual couples with a child 1-5 years old, followed for 6 months-assessed at baseline, 1, and 6 months. Frequency of child media use was assessed at baseline and 6 months through parent report across eight items (e.g., television [TV], smartphone, tablet use). Child externalizing behavior was assessed through the Child Behavioral Checklist, and parent stress through the Parenting Stress Index. Hypotheses were tested using structural equation modeling. Mothers were 31.8 (standard deviation [ SD ] = 4.2), fathers 33.3 ( SD  = 4.9), and children 3.0 years old ( SD  = 1.2). Structural equation models showed good overall fit. As hypothesized, we found that (H1) greater child externalizing behavior predicted greater parenting stress (β = 0.48, p  < 0.001), which predicted increases in child media use (β = 0.15, p  < 0.05); however, (H2) child media use did not predict later externalizing behavior (β = 0.06, p  = 0.23). In post hoc analyses, results differed slightly by specific type of media; for example , externalizing behavior was associated with later tablet and game use, whereas TV use predicted increases in externalizing behavior. Our results suggest that child behavior problems associate with later media use habits, possibly as a parent coping strategy, which should be considered when providing clinical guidance.

Excessive screen media use exposure is a robust childhood predictor of sedentary behavior. The association between excessive exposure to sedentary behaviors (e.g., screen media use) and motor skills and how this association differs across sociodemographic strata is an important knowledge gap that needs to be addressed. The study aims to investigate the association of motor skills and screen media use in preschool children, taking into account sociodemographic variables, physical activity, and sleep profile. A cross-sectional survey of 926 children from 27 preschools was performed. The main outcome was defined as motor skills assessed using the general motor quotient (GMQ). Independent variables included sociodemographic variables, screen media use, screen habits, physical activity, and sleep duration. Logistic regression models were used to estimate the associations between the children's motor skills and each exposure factor. More than 55 percent of the children ate while watching television and 28 percent spent a long time watching television, playing video games, or using a computer, tablet, or cell phone. Excessive screen media use increased the risk of a low GMQ by 72 percent and inactivity in children increased the odds by 90 percent; sleep duration at night decreased the odds of a low GMQ by 51 percent and daytime sleep decreased the odds by 33 percent. Excessive screen media use has been associated with poor motor skills and increased physical inactivity in children, especially among those with prolonged exposure. Our findings can alert parents to the consequences of excessive screen media use and can motivate policymakers to encourage sports and other health-promotion strategies.

Nutritional knowledge is an important cognitive facilitator that potentially helps children to follow a healthy diet. Two main information agents influence children's development of nutritional knowledge: the media and their parents. While a high amount of media consumption potentially decreases children's nutritional knowledge, parents may shape the amount of information children can gather about nutrition through their food-related mediation styles. In addition, children's individual preconditions predict how children can process the provided nutritional information. This two-wave panel study with children ( N = 719; 5-11 years) and their parents ( N = 719) investigated the main effects and interplay of children's amount of media consumption and their parents' food-related mediation styles by performing linear regression analysis. Children's individual preconditions were also considered. We measured children's self-reported amount of media consumption, children's age, sex, weight, and height (BMI). Additionally, in a parent survey we asked parents about how they communicate their rules about eating while especially focusing on active and restrictive food rule communication styles. As a dependent measure, we examined children's nutritional knowledge at Time 1 and 2. The results show that the amount of media consumption has a negative effect on children's nutritional knowledge over time. Parents' restrictive or active food-related mediation asserted no main effects and could not lever out the negative effect of the amount of media consumption. Therefore, we argue that parents should limit children's amount of media consumption to avoid the manifestation of misperceptions about nutrition.

Background: The screen-media landscape has changed drastically during the last decade with wide-scale ownership and use of new portable touchscreen-based devices plausibly causing changes in the volume of screen media use and the way children and young people entertain themselves and communicate with friends and family members. This rapid development is not sufficiently mirrored in available tools for measuring children's screen media use. The aim of this study was to develop and evaluate a parent-reported standardized questionnaire to assess 6-10-year old children's multiple screen media use and habits, their screen media environment, and its plausible proximal correlates based on a suggested socio-ecological model., Methods: An iterative process was conducted developing the SCREENS questionnaire. Informed by the literature, media experts and end-users, a conceptual framework was made to guide the development of the questionnaire. Parents and media experts evaluated face and content validity. Pilot and field testing in the target group was conducted to assess test-retest reliability using Kappa statistics and intraclass correlation coefficients (ICC). Construct validity of relevant items was assessed using pairwise non-parametric correlations (Spearman's). The SCREENS questionnaire is based on a multidimensional and formative model., Results: The SCREENS questionnaire covers six domains validated to be important factors of screen media use in children and comprises 19 questions and 92 items. Test-retest reliability (n = 37 parents) for continuous variables was moderate to substantial with ICC's ranging from 0.67 to 0.90. For relevant nominal and ordinal data, kappa values were all above 0.50 with more than 80% of the values above 0.61 indicating good test-retest reliability. Internal consistency between two different time use variables (from n = 243) showed good correlations with rho ranging from 0.59 to 0.66. Response-time was within 15 min for all participants., Conclusions: SCREENS-Q is a comprehensive tool to assess children's screen media habits, the screen media environment and possible related correlates. It is a feasible questionnaire with multiple validated constructs and moderate to substantial test-retest reliability of all evaluated items. The SCREENS-Q is a promising tool to investigate children screen media use.

Electronic cigarette use among youth and young adults has reached an epidemic proportion of growth. This study examined the direct and indirect effects of the breadth of media scanning about e-cigarette use on subsequent vaping behavior through interpersonal communication and changes in descriptive norm perceptions. We conducted a nationally representative longitudinal phone survey of 13- to 25-year-olds from June 2014 to March 2017, with 11,013 respondents who completed a baseline survey, among which 3,212 completed a follow-up 6 months later. The results from both cross-sectional and lagged analyses provided robust evidence to suggest that passive routine exposure to e-cigarette use content from more media outlets predicted increased likelihood of vaping among youth and young adults. High scanners were about twice as likely to vape as non-scanners (17% versus 9%). Mediation models using bootstrapping procedures found that breadth of scanning predicted higher descriptive norm perceptions which were associated with subsequent vaping; in addition, interpersonal communication mediated the relationship between breadth of scanning and changes in descriptive norm perceptions. These findings highlight the important roles of scanning, norm perceptions and interpersonal discussions in shaping cognition and behavior changes. The results also suggest an overall pro-e-cigarette public communication environment, which warrants further examination.

Objective　In recent years, the long-term use of media (including the Internet, video games, and social networking services) at a young age has been regarded as a problem. It has been pointed out that prolonged media usage may have an undesirable effect on the growth of adolescents from the physical, mental, and social perspectives. Junior and senior high school students are in a particularly important period of self-management of the basic lifestyle habits acquired thus far. Additionally, they must cultivate the ability to interact appropriately with media used daily. In this study, we investigated the relationship between the time expended on media usage and lifestyle habits among junior and senior high school students.Methods　A sample of 1,633 students was extracted from all junior and senior high schools in Fukushima City. Principals of the schools distributed a self-administered questionnaire to their students. In total, 1,589 responses were obtained; as surveys of 30 students were missing values for gender and grade, they were excluded from the analysis, and data from 1,559 respondents were ultimately analyzed. A binomial logistic regression analysis was performed to examine the relationship between an independent variable (media usage time) and dependent variables (subjective health, lifestyle habits, and drinking and smoking experience) while controlling for gender and grade.Results　Among junior high students, media usage for more than three hours was significantly related to "no breakfast," "no exercise habits," "irregular sleep," "lack of rest," and "feeling stressed." Among high school students, media usage for three hours or more was significantly related to "poor subjective health status," "eating only one or two meals a day," "no breakfast," "low food diversity," "obesity," "no exercise habits," "irregular sleep," "late bedtime," "waking up late," "drinking," and "smoking."Conclusion　Our findings indicate that three or more hours of daily media usage is related to unhealthy lifestyles in terms of sleeping, eating, physical activity, drinking, and smoking. Junior and senior high school students who responded to the survey indicated that prolonged usage was also adversely related to their subjective health. Because the overuse of media is associated with students' lifestyles and health, it is important to develop an educational system that helps junior and senior high school students use media properly.

To understand how the sustainable development goals (SDGs) are involved and cited in different fields, the current study aimed to explore the key SDGs and SDG-pairs from the viewpoints of academia and the media. The academic publications with SDG(s)-related keywords in the Scopus database and the entry videos of the "2018 SDG Lions" were collected and analyzed through content and network analysis. It was found that SDG 3 and SDG 10 shared the highest preferences in both industries, but apparent gaps happened to SDG 5. The tied frequencies of the possible SDG pairs were also examined, and SDG 3-10 was identified taking the lead in both industries. Network analysis using degree centrality as the vital parameter demonstrated that SDG 8 and SDG 5 has strong connections with several SDGs for the academia and the media, respectively. The SDG-2-6-7 combination or "water-energy-food" nexus was also found the most frequent combination of three SDGs in the academia. Overall, SDG 3 can be treated as a unifying theme when seeking to acquire evidence-based knowledge for integrated implementation of the SDGs. Important implications for policy-making of the SDGs were also discussed.

Objectives and importance of study: News media portrayal of public health issues influences public opinion, policy action and decision making. This study aimed to analyse the use of 'nanny state' frames in Australian news media coverage; identify the stakeholders invoking this frame; determine which public health-related policies attract such framing; and investigate whether 'nanny state' framing is directly challenged in news coverage., Study Type: A qualitative framing analysis., Methods: Articles featuring the term 'nanny state' that were published in Australian print newspapers during matched periods between March and September in 2017 and 2018 were sourced through Factiva, coded and analysed for content and 'nanny state' framing. Content analysis was used to identify any public health-related issues that the terminology nanny state was applied to, and who was portrayed as imposing the nanny state. Frame analysis was used to analyse what meanings are co-presented with the phrase nanny state., Results: Out of 81 print newspaper articles that included the term 'nanny state', 19% linked the term to restricting personal choice or creating dissatisfaction with too many health-related rules and regulations broadly, across a range of issues, including: bike helmets, e-cigarettes, firearm restrictions, seatbelts, pool fences and smoking bans. The next most frequent links were to regulations on alcohol (17%), road safety (14%), obesity-related issues (7%) and tobacco control (6%). Of the 81 articles, 53% appeared in news publications owned by News Corporation Australia, 20% in Fairfax Media (Nine Entertainment) publications, 17% in Daily Mail and General Trust and 10% in publications owned by other organisations. Governments were the entity most frequently framed as imposing the nanny state. Most nanny state framings (73%) were negative towards public health controls and focused on policies and regulations. Nanny state was portrayed as an assault on freedom and choice (14%) and used to attack proponents of nanny state controls (11%), while few articles framed the nanny state (7%) in a favourable light., Conclusions: 'Nanny state' is a rhetorical device commonly used in Australian news media that may contribute to discrediting of the regulation of a range of health-related issues. News Corp publications are a major propagator of nanny state rhetoric in Australian newspaper media. Public health advocates are not commonly represented within nanny state debates within the news media., Competing Interests: None declared.

Background: Between 2015 and 2017 six deaths due to meningitis in the Lombardy Region, Northern Italy, caught the attention of media and increased concern among the population, with a consequent increase in demand for vaccination. Considering the evidence about the impact of media coverage of health issues on public behaviour, this paper investigates the trend of media coverage and internet searches regarding meningitis in the Lombardy Region., Methods: Content analysis of online articles published from January 2015 to May 2017 and analysis of Google Trends were carried out. A codebook was created in order to assess the content of each article analysed, based on six areas: article characteristics, information about meningococcal disease and vaccination, Local Health Authority activities, accuracy of information and tone of the message., Results: Both public interest and media attention peaked in December 2016 and January 2017, when the Lombardy Regional Authority changed its policy by offering co-payment to adults with a saving of 50%. The frequency of meningitis coverage decreased after the announcement of policy change. For example, articles containing new information on meningitis or meningococcal vaccine (76 to 48%, p = 0.01) and preventive recommendations (31% down to 10%, p = 0.006) decreased significantly. An alarmist tone appeared in 21% of pre-policy articles that decreased to 5% post-policy (p = 0.03)., Conclusions: The findings suggest a role for the media in fostering public pressure towards health services and policy-makers. A collaboration between Public Health institutions and the media would be beneficial in order to improve communication with the public.

Information and communications technology (ICT) has developed economies and the way of energy consuming through the access, analysis, planning, and management of information. Such innovation, hence, explains the important direct effects on the environment and carbon dioxide (CO 2 ) emissions in a region or causes the spillover effects on other regions. This research examines the relationship between ICT and CO 2 emissions to have both within-region effects and spillover effects on other regions. In this way, ICT and the square of ICT were combined into the environmental Kuznets curve to specify the direct, spatial spillover, and total effects of ICT on CO 2 emissions. The dynamic spatial Durbin model was used to estimate the effects of ICT on the provinces of Iran for a period of 2001 to 2015. The results showed that the spatial spillover effects of ICT on CO 2 emissions have an inverted U-shaped relationship in short and long run. This findings show that an increase in the ICT in a province first causes to increase and then decrease the CO 2 emissions in other provinces.

Prepackaged leafy green vegetables represent one of the fastest growing segments of the fresh-produce industry in the United States. Several steps in the production process have been mechanized to meet the downstream demand for prebagged lettuces. The growth in this market, however, has come with drawbacks, and chief among them are consumers finding wild animals in prepackaged crops. These incidents may signal an overburdened produce supply chain, but we currently lack the information needed to determine if this is a food-safety problem or food-quality concern. Here, we address this gap by reviewing online media coverage of wild vertebrates found in prepackaged produce items by customers in the United States. We discovered 40 independent incidents since 2003 with 95% having occurred during 2008-2018, suggesting that the frequency of incidents may have increased during the last decade. The minority of incidents included wild animals found in organic produce (27.5%), whereas the majority involved conventionally grown crops (72.5%). Most incidents involved amphibians (52.5%) and reptiles (22.5%), while fewer contained mammals (17.5%) and birds (7.5%). Frogs and toads made up all of the amphibian-related incidents, with more than 60% comprising small-bodied treefrogs found in various types of fresh leafy greens. At least seven incidents involved Pacific Treefrogs (Hyliola regilla) and three comprised Green Anoles (Anolis carolinensis). One lizard and nine frogs were found alive, and at least two frogs were released into non-native areas. This is the first review quantifying incidents of vertebrates found by customers in prepackaged produce, yet it remains unclear whether these occurrences indicate a food-safety crisis or a complaint against food quality. Nevertheless, wild animals can spread diseases to humans via contaminated produce, therefore we contend that industry professionals can reduce the potential health risk to their consumers and negative economic consequences to themselves through increased attention to this matter., (Copyright © 2019 The Authors.

Colorectal cancer (CRC) is one of the most common cancers in the USA. In 2017, an estimated 135,420 people were diagnosed with CRC and 50,260 people died from CRC. Several screening modalities are recommended by the United States Preventive Services Task Force (USPSTF), including annual stool tests that are usually completed at home and under-used compared with colonoscopy despite stated patient preferences for an alternative to colonoscopy. The Community Preventive Services Task Force recommends use of small media interventions (SMIs) to increase CRC screening and calls for a greater understanding of its independent impact on screening participation. This study tested whether a SMI increased the likelihood of participant return of a USPSTF recommended Fecal Immunochemical Test (FIT). In total, 804 individuals participated in a two-group, prospective randomized controlled trial. Descriptive statistics with chi-square tests compared differences in participant characteristics and return rates. Multivariable log-binomial modeling estimated combined effects of patient characteristics with FIT return rates. No differences in return rates were observed overall or by participant characteristics other than the year of enrollment. A multivariable model controlling for all covariates, found gender, insurance type, and regular place for healthcare to be significantly associated with return rates. Receipt of the SMI did not independently increase overall return rates but it may have improved the ease of completing the FIT by some participants, particularly women, those with insurance, and those with a regular place for healthcare., (© Society of Behavioral Medicine 2018.

Purpose: The knowledge about the association between Information and Communication Technology (ICT) demands at work and self-rated health (SRH) is insufficient. The aim of this study was to examine the association between repeated exposure to high ICT demands at work, and risk of suboptimal SRH, and to determine modifications by sex or socioeconomic position (SEP)., Methods: A prospective design was used, including repeated measurement of ICT demands at work, measured 2 years apart. SRH was measured at baseline and at follow-up after 4 years. The data were derived from the Swedish Longitudinal Occupational Survey of Health (SLOSH), including 4468 gainfully employees (1941 men, 2527 women) with good SRH at baseline., Results: In the total study sample, repeated exposure to high ICT demands at work was associated with suboptimal SRH at follow-up (OR 1.34 [CI 1.06-1.70]), adjusted for age, sex, SEP, health behaviours, BMI, job strain and social support. An interaction between ICT demands and sex was observed (p = 0.010). The risk was only present in men (OR 1.53 [CI 1.09-2.16]), and not in women (OR 1.17 [CI 0.85-1.62]). The risk of suboptimal SRH after consistently high ICT demands at work was most elevated in participants with high SEP (OR 1.68 [CI 1.02-2.79]), adjusted for age, sex, health behaviours, BMI and job strain. However, no significant interaction between ICT demands and SEP regarding SRH was observed., Conclusion: Repeated exposure to high ICT demands at work was associated with suboptimal SRH at follow-up, and the association was modified by sex.

Objective: The purpose of this study was to compare the effectiveness of four different design communication media in helping clinical end users understand spatial and functional information and in supporting their ability to provide design feedback., Background: It is critical to involve clinical end users early in the design process to test design solutions and ensure the design of a new healthcare facility supports their ability to deliver high-quality care. Traditional architectural design communication media such as floor plans and perspectives can be challenging for clinical design team members to understand. Physical and virtual mock-ups are becoming more popular as design communication media. However, nominal evidence exists comparing the effectiveness of different design media in supporting clinical end-user engagement and contribution during the design process., Method: An exploratory, qualitative study was conducted with clinical end users to evaluate the effectiveness of four different media commonly used in design communication., Results: Traditional architectural representations convey limited useful information to clinical end users, impacting the amount and type of feedback they can provide. More immersive media, such as physical and virtual mock-ups, support an increasingly holistic understanding of proposed design solutions, inciting more design solutions that range from the inclusion and exclusion of design features to location, position, and functionality of those features., Conclusions: When used in combination, each media can contribute to eliciting clinical end-user feedback at varying scales. The overall preference and higher effectiveness in eliciting design feedback from clinical end users highlights the importance of physical mock-up in communicating healthcare design solutions.

Social representation theory provides a framework for studying how scientific knowledge affects common sense and communication through inquiries into everyday discourse. This qualitative study examined social representations of chronic pain from 4 sources: North American newspapers; "Chronic Illness Cat" memes from the social media web site, Pinterest; video blogs on YouTube; and from a 2014 film, Cake, and interviews and comments concerning it. Using thematic analysis, we first identified social representations found in our 4 sources and others found in 1 or 2 of them. Second, we analyzed the sources for their rhetorical intentions. Vlogs directly and memes indirectly were first-person accounts, self-authorizing statements of the truth of chronic pain, whereas newspaper articles and the film were third-person accounts of pain, the differences between these perspectives affecting what was said. We conclude that the medium shapes the message.

The widespread use of digital technologies by young people has spurred speculation that their regular use negatively impacts psychological well-being. Current empirical evidence supporting this idea is largely based on secondary analyses of large-scale social datasets. Though these datasets provide a valuable resource for highly powered investigations, their many variables and observations are often explored with an analytical flexibility that marks small effects as statistically significant, thereby leading to potential false positives and conflicting results. Here we address these methodological challenges by applying specification curve analysis (SCA) across three large-scale social datasets (total n = 355,358) to rigorously examine correlational evidence for the effects of digital technology on adolescents. The association we find between digital technology use and adolescent well-being is negative but small, explaining at most 0.4% of the variation in well-being. Taking the broader context of the data into account suggests that these effects are too small to warrant policy change.

The increasing demand for network applications, such as teleconferencing, multimedia messaging and mobile TV, which have diverse requirements, has resulted in the introduction of Long Term Evolution (LTE) by the Third Generation Partnership Project (3GPP). LTE networks implement resource allocation algorithms to distribute radio resource to satisfy the bandwidth and delay requirements of users. However, the scheduling algorithm problem of distributing radio resources to users is not well defined in the LTE standard and thus considerably affects transmission order. Furthermore, the existing radio resource algorithm suffers from performance degradation under prioritised conditions because of the minimum data rate used to determine the transmission order. In this work, a novel downlink resource allocation algorithm that uses quality of service (QoS) requirements and channel conditions to address performance degradation is proposed. The new algorithm is formulated as an optimisation problem where network resources are allocated according to users' priority, whereas the scheduling algorithm decides on the basis of users' channel status to satisfy the demands of QoS. Simulation is used to evaluate the performance of the proposed algorithm, and results demonstrate that it performs better than do all other algorithms according to the measured metrics., Competing Interests: The authors have declared that no competing interests exist.

The epidemiology of occupational injuries is reported worldwide, but suspicions of under-reporting prevail, probably associated with free press. We examined the association between freedom of the press and lethality rate of occupational injuries based on the most comprehensive International Labour Organization database on labour statistics (ILOSTAT) among 39 countries. The occupational injury indices, national indicators, and information on freedom of the press in 2015 were sourced from ILOSTAT, World Bank open data, World Health Organization and Freedom House. The lethality rate was the number of fatal occupational injuries per 10,000 total occupational injuries. The relationship among fatal and total occupation injury rates, lethality rate, and national statistics were analysed using Spearman's rank correlation coefficients. Multivariable linear regression models with bootstrap estimation to manage non-normality determined freedom of the press associated with lethality rate. Freedom of the press was significantly correlated with fatal and total occupational injury rate and lethality rate of occupational injuries. Adjusting for national indicators, only freedom of the press was associated with lethality rate per 10,000 occupational injuries in the report of ILOSTAT. The lethality rate of occupational injury reported by each country might not reflect the actual lethality, but under-reported nonfatal occupational injuries, probably relating to freedom of the press.

Smoking in pregnancy remains a global public health issue due to foetal health risks and potential maternal complications. The aims of this systematic review and meta-analysis were to explore: (1) whether digital interventions for pregnancy smoking cessation are effective, (2) the impact of intervention platform on smoking cessation, (3) the associations between specific Behaviour Change Techniques (BCTs) delivered within interventions and smoking cessation and (4) the association between the total number of BCTs delivered and smoking cessation. Systematic searches of 9 databases resulted in the inclusion of 12 published articles (n = 2970). The primary meta-analysis produced a sample-weighted odds ratio (OR) of 1.44 (95% CI 1.04-2.00, p = .03) in favour of digital interventions compared with comparison groups. Computer-based (OR = 3.06, 95% CI 1.28-7.33) and text-message interventions (OR = 1.59, 95% CI 1.07-2.38) were the most effective digital platform. Moderator analyses revealed seven BCTs associated with smoking cessation: information about antecedents; action planning; problem solving; goal setting (behaviour); review behaviour goals; social support (unspecified); and pros and cons. A meta-regression suggested that interventions using larger numbers of BCTs produced the greatest effects. This paper highlights the potential for digital interventions to improve rates of smoking cessation in pregnancy.

Introduction: Online media may influence women's decision to undergo vaccination during pregnancy. The aims of this mixed-methods study were to: (1) examine the portrayal of maternal vaccination in online media and (2) establish the perceived target of vaccine protection as viewed by pregnant women and maternity healthcare professionals (HCPs)., Methods: Online media articles on maternal vaccination (published July-December 2012 or November 2015-April 2016) were identified through the London School of Hygiene & Tropical Medicine's Vaccine Confidence Database and thematically analysed. Questionnaires for pregnant women and HCPs were distributed within four English hospitals (July 2017-January 2018)., Results: Of 203 articles identified, 60% related to pertussis vaccination, 33% to influenza and 6% both. The majority positively portrayed vaccination in pregnancy (97%), but inaccurate, negative articles persist which criticize pertussis vaccination's safety and efficacy. Positively-worded articles about pertussis tended to focus on infant protection and highlight examples of recent cases, whereas positively-worded articles about influenza focused on maternal protection. These themes were reflected in questionnaire responses from 314 pregnant women and 204 HCPs, who perceived pertussis vaccination as protecting the baby, and influenza vaccination as protecting the mother, or mother and baby equally. A minority of the pregnant women surveyed intended to decline influenza (22%) or pertussis (8%) vaccination., Conclusions: The majority of online articles support pertussis and influenza vaccination during pregnancy. The portrayal of pertussis vaccination as primarily benefiting the child, using real-examples, may influence its higher uptake compared with influenza. This approach should be considered by HCPs when recommending vaccination. HCPs should be prepared to provide advice to women hesitant about vaccination, including addressing any negative media, and consider educational strategies to counteract inaccurate information. Future studies should directly assess the influence of media on vaccine decision-making and establish which media platforms are typically used by pregnant women to gather information., (Copyright © 2018 The Author(s).

Adolescents are constantly connected with each other and the digital landscape through a myriad of screen media devices. Unprecedented access to the wider world and hence a variety of activities, particularly since the introduction of mobile technology, has given rise to questions regarding the impact of this changing media environment on the mental health of young people. Depressive symptoms are one of the most common disabling health issues in adolescence and although research has examined associations between screen use and symptoms of depression, longitudinal investigations are rare and fewer still consider trajectories of change in symptoms. Given the plethora of devices and normalisation of their use, understanding potential longitudinal associations with mental health is crucial. A sample of 1,749 (47% female) adolescents (10-17 years) participated in six waves of data collection over two years. Symptoms of depression, time spent on screens, and on separate screen activities (social networking, gaming, web browsing, TV/passive) were self-reported. Latent growth curve modelling revealed three trajectories of depressive symptoms (low-stable, high-decreasing, and low-increasing) and there were important differences across these groups on screen use. Some small, positive associations were evident between depressive symptoms and later screen use, and between screen use and later depressive symptoms. However, a Random Intercept Cross Lagged Panel Model revealed no consistent support for a longitudinal association. The study highlights the importance of considering differential trajectories of depressive symptoms and specific forms of screen activity to understand these relationships.

Background: Digital spaces, and in particular social networking sites, are becoming increasingly present and influential in the functioning of our democracies. In this paper, we propose an integrated methodology for the data collection, the reconstruction, the analysis and the visualization of the development of a country's political landscape from Twitter data., Method: The proposed method relies solely on the interactions between Twitter accounts and is independent of the characteristics of the shared contents such as the language of the tweets. We validate our methodology on a case study on the 2017 French presidential election (60 million Twitter exchanges between more than 2.4 million users) via two independent methods: the comparison between our automated political categorization and a human categorization based on the evaluation of a sample of 5000 profiles descriptions; the correspondence between the reconfigurations detected in the reconstructed political landscape and key political events reported in the media. This latter validation demonstrated the ability of our approach to accurately reflect the reconfigurations at play in the off-line political scene., Results: We built on this reconstruction to give insights into the opinion dynamics and the reconfigurations of political communities at play during a presidential election. First, we propose a quantitative description and analysis of the political engagement of members of political communities. Second, we analyze the impact of political communities on information diffusion and in particular on their role in the fake news phenomena. We measure a differential echo chamber effect on the different types of political news (fake news, debunks, standard news) caused by the community structure and emphasize the importance of addressing the meso-structures of political networks in understanding the fake news phenomena., Conclusions: Giving access to an intermediate level, between sociological surveys in the field and large statistical studies (such as those conducted by national or international organizations) we demonstrate that social networks data make it possible to qualify and quantify the activity of political communities in a multi-polar political environment; as well as their temporal evolution and reconfiguration, their structure, their alliance strategies and their semantic particularities during a presidential campaign through the analysis of their digital traces. We conclude this paper with a comment on the political and ethical implications of the use of social networks data in politics. We stress the importance of developing social macroscopes that will enable citizens to better understand how they collectively make society and propose as example the "Politoscope", a macroscope that delivers some of our results in an interactive way., Competing Interests: The authors have declared that no competing interests exist.

Scientific communication through social media, particularly Twitter has been gaining importance in recent years. As such, it is critical to understand how information is transmitted and dispersed through outlets such as Twitter, particularly in emergency situations where there is an urgent need to relay scientific information. The purpose of this study is to examine how original tweets and retweets on Twitter were used to diffuse radiation related information after the Fukushima Daiichi nuclear power plant accident. Out of the Twitter database, we purchased all tweets (including replies) and retweets related to Fukushima Daiichi nuclear power plant accident and or radiation sent from March 2nd, 2011 to September 15th, 2011. This time frame represents the first six months after the East Japan earthquake, which occurred on March 11th, 2011. Using the obtained data, we examined the number of tweets and retweets and found that only a small number of Twitter users were the source of the original posts that were retweeted during the study period. We have termed these specific accounts as "influencers". We identified the top 100 influencers and classified the contents of their tweets into 3 groups by analyzing the document vectors of the text. Then, we examined the number of retweets for each of the 3 groups of influencers, and created a retweet network diagram to assess how the contents of their tweets were being spread. The keyword "radiation" was mentioned in over 24 million tweets and retweets during the study period. Retweets accounted for roughly half (49.7%) of this number, and the top 2% of Twitter accounts defined as "influencers" were the source of the original posts that accounted for 80.3% of the total retweets. The majority of the top 100 influencers had individual Twitter accounts bearing real names. While retweets were intensively diffused within a fixed population, especially within the same groups with similar document vectors, a group of influencers accounted for the majority of retweets one month after the disaster, and the share of each group did not change even after proven scientific information became more available., Competing Interests: The authors have declared that no competing interests exist.

In recent years, yaoi has been increasingly popular among youth interested in Japanese media such as anime and manga. Yaoi is defined as commercial and fan-created media that thematically focus on the romantic love between two men, often in a sexually explicit way. Despite the widespread popularity of this Japanese subgenre, there is a lack of empirical studies on the motives for consuming yaoi media that analyze the full range of motives using reliable research methods. The present study aimed to explore and operationalize the motives for yaoi media consumption based on previous qualitative research (Pagliassotti, 2008). Using an online survey, 724 yaoi consumers (58% male; Mage = 30.1 years, SD = 10.4) completed the Yaoi Consumption Motives Questionnaire (YCMQ). According to confirmatory factor analyses, the bi-factor model of nine motives yielded closer fit to the data than the theoretically proposed, first-order ten-factor model and a second-order nine-factor model. The nine-factor YCMQ demonstrated strong psychometric properties in terms of factor structure, internal consistency, and measurement invariance. These results indicate that the 31-item YCMQ is an appropriate instrument to assess individuals' motives for consuming yaoi media., Competing Interests: The authors have declared that no competing interests exist.

Background: Electronic cigarettes (E-cigarettes) have become a debated issue for tobacco control over recent years. In this study we investigate how Chinese newspapers have covered E-cigarettes over the past ten years., Methods: The study analyses the salience, patterns and content of news articles pertaining to E-cigarettes in regional and national Chinese outlets. A total of 476 articles are examined via content analysis and supervised automatic text analysis. The manual content analysis generates a coding scheme, which is then validated and applied to machine learning. The whole research methodology demonstrates satisfying human-human and human-to-computer reliabilities., Results: The study reveals that E-cigarettes have not received enough attention in terms of its salience in the media, though the amount of coverage has been growing. A large share of the articles is published around May of each year - which is when the No Tobacco Day of the WHO takes place. The results point to four major themes on E-cigarettes: nicotine/constituents/features, tobacco control/regulation, children's use of E-cigarettes, and tobacco market/industry., Conclusions: Overall, E-cigarettes have not been a topic at the top of media agenda; however, we have identified a considerable growth of coverage about the potential concerns regarding young people's adoption of E-cigarettes advocated by parents and educators.

Background: U.S. seniors' digital health and everyday technology use when their health declines are unknown., Methods: Longitudinal cohort using the National Health and Aging Trends Study, a nationally representative, annually administered sample of community-dwelling Medicare beneficiaries (n = 4,037). We used difference-in-differences to assess the adjusted difference (AD) in technology use from 2011 to 2014 between those with and without health declines. Health decline measures included new-onset dementia; new-onset depression; decreases in activities of daily living (ADLs), short physical performance battery (SPPB), grip strength, and self-reported health; relocation to nursing facility; increased hospitalizations; and new-onset comorbidity. Digital health included use of the Internet to research health conditions, contact clinicians, fill prescriptions, and address insurance matters., Results: Between 2011 and 2014, seniors experiencing health decline used various digital health technologies at low absolute rates (range: 1%-20%). Between 2011 and 2014, use of everyday technology decreased significantly among seniors with new-onset dementia (from 73% to 51%; AD, -26%), decreased ADLs (from 76% to 67%; AD, -10%), decreased SPPB (from 88% to 86%; AD, -3%), and relocation to a nursing facility (from 49% to 22%; AD, -31%) compared to seniors without comparable decline (all p < .05). Use of digital health decreased significantly among seniors with new-onset probable dementia (from 9% to 4%; AD, -6%) and decreased SPPB (from 24% to 25%; AD, -4%; all p < .05)., Conclusions: The type of health decline a senior experiences predicts technology use, which may allow better targeting of digital health to specific seniors. Seniors with new dementia, relocation to a nursing home, and declining physical performance seem especially poor candidates for technology interventions.

Akçay D, Akçay BD. The influence of media on the sleep quality in adolescents. Turk J Pediatr 2018; 60: 255-263. This study was conducted to evaluate the influence of media devices on sleep quality in adolescents. Applying a descriptive design, the study was carried out with 9th, 10th and 11th grade students (N=392, 52.0% female, average age 16.04±0.86) who were attending Konya High School between the dates of January 18 and 22, 2016. Changes were seen to occur in the wake-up times of those who had either a television or a computer in their bedrooms (p < 0.005, p < 0.05, respectively). Overall, it was determined that the students who participated in the study had poor sleep quality (66.6%). A positive correlation was detected between the amount of time the adolescents spent watching TV, using the internet, and playing games on their mobile phone, and the wake-up times (r=0.154, p < 0.005; r=0.152, p < 0.005; r=0.258, p < 0.001; r=0.232, p < 0.001, respectively). A negative correlation was detected between playing computer/console games and listening to music and sleep duration in the adolescents (respectively, r=-0.149, p < 0.005; r=-0.107, p < 0.05). The results showed that as the adolescents spent more time with their media products (except TV watching), their sleep quality deteriorated. In adolescents, the duration and quality of sleep were found to be affected by certain aspects of media use. It is therefore recommended that families regulate the intended purpose and content of their children's media use and limit the time spent with media. Moreover, media products should be removed from their bedrooms. More training and intervention studies on sleep patterns and media literacy should be conducted with this study group.

Immunization polices in Italy has recently reached important milestones, including the approval of the National Immunization Prevention Plan and of a new law mandatory immunization; this stimulating a lively debate at the scientific, political and societal-level, reflected on the media. We applied a model previously published to quantitatively and qualitatively assess media coverage on vaccines and immunization-related topics on the most read Italian newspaper, "Corriere della Sera", over an 11-year study period (2007-2017). We retrieved relevant key words and articles, reported on included articles' topic, position, approach to immunization and on other selected indicators' summary statistics, temporal trends and correspondence with key epidemiological and policy events. Over the study period the quote "vaccin*" was mentioned on average 325 times per year; with an increase of 150% after the approval of the new law on mandatory immunization in 2017. In the same year, on average, two first-page articles per week were published on the topic. We report a clear association between key events (i.e the H1N1 influenza pandemic, the "Fluad case", the approval of the new law on mandatory immunization) and their media coverage. Overall, 84% of articles had a positive attitude towards immunization, this share decreasing to 79% when only considering articles published after the approval of the law on mandatory vaccination. Media play a crucial role in channelling health-related information and significantly influence health behaviours. We urge public institutions, health authorities and the scientific community not to underestimate the opportunity to monitor media coverage on key healthcare topics and to convey evidence-based health education messages through the media.

Background: Older adults are increasingly using information and communication technologies (ICTs). Recent studies show beneficial effects of using ICTs for older adults, particularly in terms of reducing loneliness and depression. However, little is known about the factors that may prevent discontinued ICT use in populations that may be at greater risk, such as those in continuing care retirement communities (CCRCs)., Objectives: The purpose of this study is to examine a range of factors that may influence discontinued (1) ICT use, (2) searching for health information, and (3) searching for general information over time among CCRC residents., Methods: We use longitudinal data from a randomized controlled trial conducted with residents of 19 CCRCs. We use flexible parametric models to estimate the hazard ratio or hazard rate over 5 waves of data to determine what factors significantly predict discontinued (1) ICT use, (2) health information searching, and (3) general information searching., Results: The analysis reveals that independent living residents who took part in an 8-week ICT training intervention were less likely to stop using ICTs. Age and the number of instrumental activities of daily living (IADL) impairments significantly predicted an increased likelihood of stopping ICT use. When examining specific ICT-related activities, the analysis reveals that independent living residents who took part in the ICT training intervention were less likely to stop searching for health information and general information online. In addition, age and the number of IADL impairments were associated with increased likelihood of discontinued health information searches and discontinued general information searches., Conclusion: ICT training interventions may motivate residents of CCRCs to stay connected by increasing the ICT skill level and promoting confidence, thus decreasing the probability that they will discontinue using ICTs and searching for general information. However, the effects of ICT training on motivating continued ICT usage may be more pronounced among independent living residents. Limitations in the number of IADL impairments is a key factor leading to discontinued use of ICTs among CCRC residents, suggesting that designers of ICTs should be cognizant of the cognitive and physical limitations among this group., (© 2017 S.
