Evaluation of the 'A walk can work wonders' mass media campaign in South Australia.

ISSUE ADDRESSED: Few population-wide efforts have targeted physical activity in Australia. Mass media campaigns are used to promote physical activity and walking, and World Health Organisation recommends their linkage to broader cross-government initiatives. This project evaluates a South Australian (SA) walking mass media campaign linked to the overall SA Walking Strategy. METHODS: Between January and June 2022, Wellbeing SA (a SA government agency) conducted two waves of a mass media campaign, 'A walk can work wonders', to promote walking. The campaign was part of the SA Walking Strategy, targeting the goal to change the 'community culture towards recognising walking' as convenient, affordable and health-promoting. Evaluation was formative (pre-campaign), process (campaign implementation and delivery) and impact. Formative evaluation comprised concept and tagline testing with adult SAs to develop the campaign messages and theme. Process evaluation was comprised of media monitoring of social media, mainstream media and other media monitoring metrics. The process evaluation was dominated by social media marketing in Wave 1, with substantially more paid TV media and radio in Wave 2. The impact evaluation comprised two independent sample surveys of adult SAs (n = 800 each) following each wave of the campaign. Measures included generic and prompted campaign recall and attitudes to physical activity. An independent South Australian Population Health Survey (SAPHS) tracked walking and physical activity behaviours from 2021 to the end of 2022. RESULTS: Process evaluation showed intensive social media usage in Wave 1, and through increased paid television and radio in Wave 2. Generic recall of any walking message (23.9%) and prompted recall of the specific campaign message (27.8%) reached most socio-demographic groups, especially those with chronic health problems. Increases in intention to increase activity and increased self-reported activity were seen between the campaign Wave 1 and Wave 2 notable as the Wave 2 increase followed substantial television advertising. The SAPHS data showed increased population walking following the campaign waves, compared to the same period in 2021. CONCLUSIONS: Detailed and structured evaluation of a comprehensive mass media campaign showed good reach, and population changes in intentions and walking behaviour amongst SAs. SO WHAT?: It is likely that comprehensive approaches are needed to support mass media campaigns and amplify their effects. Serial, sustained campaigns are needed to monitor ongoing effects.

"I have learned that nothing is given for free": an exploratory qualitative evaluation of a social norms edutainment intervention broadcast on local radio to prevent age-disparate transactional sex in Kigoma, Tanzania.

BACKGROUND: Promising evidence supports the effectiveness of edutainment interventions in shifting norms to prevent violence against women and girls and other harmful practices, yet further research into mechanisms and pathways of impact is needed to inform intervention development, delivery and scale-up. This exploratory qualitative evaluation examined the feasibility and indications of change in attitudes, beliefs, norms and behaviours following the broadcast of a radio drama aired to prevent age-disparate transactional sex in Kigoma, Tanzania. METHODS: Over seven weeks, six episodes were broadcast on local radio weekly, between November and December 2021 in Kigoma, targeting adolescent girls (aged 13-15 years) and their caregivers. Reflection sessions were conducted twice a week with 70 girls across seven schools, supplemented by after-school Girls' Club listening sessions for a subgroup of 30 girls. We conducted seven before and after focus group discussions, five with girls (n = 50), one with men caregivers (n = 9) and one with women caregivers (n = 9) and analysed them using thematic and framework analysis approaches. RESULTS: Overall, we found that while girls exhibited significant engagement with the drama, caregiver participation, particularly among men, was low. Thus, no clear changes were detected in men. We did not find any differences in impact based on listening sessions' attendance vs. home listening. We detected positive changes among girls and women in four thematic areas after listening to the drama: (1) participant's increasingly challenged perceptions about what kinds of girls and men take part in age-disparate transactional sex, what can be exchanged, and men's motivations for engaging; (2) there was a shift from attributing blame for age-disparate transactional sex relationships from girls to men; (3) girl's reported increased agency and confidence to avoid age-disparate transactional sex relationships; and (4) we found a heightened sense of responsibility and recognition for the role of parents, peers and community members in preventing age-disparate transactional sex. CONCLUSIONS: These findings highlight the need for further implementation research to explore ways to effectively engage men. They also underscore the potential of engaging, evidence-based edutainment interventions in fostering spontaneous critical reflection about complex behaviours such as age-disparate transactional sex, and diffusing key messages among target populations without the use of organised diffusion activities.

Changes in Sources of Information about the Risks and Benefits of Cannabis in a National Cohort of US Adults from 2017 - 2021.

OBJECTIVE: As more states legalize cannabis in the US, marketing from the cannabis industry and news coverage of cannabis have increased. Sources of information on cannabis can influence beliefs about risks and benefits. Yet, little is known about how the use and influence of specific sources of information have changed over time. METHOD: We conducted a longitudinal study of 5053 US adults between 2017 and 2021. Participants were asked about sources of information on cannabis risks and benefits and which sources were most influential using a web-based survey at three different time points (2017, 2020, 2021). We evaluated changes in the use/influence of multiple sources of information from 2017 to 2021 and examined interactions with age, cannabis use and state cannabis legal status. RESULTS: The largest increases in sources of information on cannabis benefits and risks were in use of health professionals (+5.5% for benefits and +17.4% for risks). The largest declines were in use of traditional media (TV, radio, newspapers) (-12.3% and -11.4%). Use of cannabis advertisements and dispensaries/other industry sources also significantly increased. Health professionals were the most influential source of information in all three waves regardless of age, cannabis use or state legal status. CONCLUSIONS: Participants sought information from different sources, and increasingly relied on health professionals as a primary source, highlighting the need to train healthcare providers about cannabis risks and benefits. While fewer people used traditional media, use of industry sources increased, underscoring the need for accurate cannabis information sources.

Assessing the reach and engagement with the 'How To Save A Life' mass media campaign on drug-related death prevention in Scotland.

'How To Save A Life' (HTSAL) was a mass media campaign on drug-related death prevention which ran in Scotland from August 2021 to January 2022. It aimed to increase awareness of how to respond to an opioid overdose, and the uptake of take-home naloxone (THN). The objective of this study was to determine the reach and engagement with the campaign. Methods included a descriptive analysis of data from media sources, the campaign website, and an online naloxone training course. A quantitative content analysis was conducted on media articles. The campaign generated 57,402,850 non-unique impressions (the total number of times the campaign was seen or heard), and unique reach (the number of people who were exposed to the campaign) figures of 2,621,450. Engagement with the campaign was positive, and 96% of print/digital media articles had a positive view of the campaign. There were 40,714 visits to the campaign website, leading to 8,107 clicks to the free naloxone training course, and 3,141 clicks to order a free naloxone kit. This study showed that mass media campaigns on drug policy topics can achieve high levels of reach and engagement. There was a clear progression from viewing campaign materials, to visiting the campaign website, to completing naloxone training. Our research suggests that mass media campaigns can be used to disseminate harm reduction messages to the general public.

Mass Media Exposure Moderates the Association of Education and Wealth with Enrollment in Health Insurance Among Older Adults Aged 60 Years and Older in India.

Mass media exposure (MME) plays an important role in changing health-related behavior or decision-making. This study aimed to examine the association of MME with enrollment in health insurance and its moderating effect on the associations of education and wealth with enrollment in health insurance among older adults in India. The data of 29,935 older adults aged 60 years and older from the first wave (baseline) of the Longitudinal Ageing Study in India (LASI-2017/18) were utilized. Descriptive statistics, bivariate analysis, multivariable logistic regression models, and Fairlie decomposition were used. The findings revealed that 18.3% of older adults had MME and enrollment in health insurance in India. Older adults with MME were 1.42 times more likely to be enrolled in health insurance than those with no MME, and years of schooling increased the probability of enrolling in health insurance compared to those who did not have formal schooling. With increasing monthly per capita expenditure (MPCE), the probability of enrolling in health insurance is lower than the poorest. Further, MME moderates the effects of education and MPCE on enrollment in health insurance and increases the likelihood of enrollment in health insurance. The study's findings imply strategic communication plans to encourage health insurance enrollment in India should take into account the usage of these communication channels.

Everyday Healthcare Regulation: British Newspapers and Complementary and Alternative Medicine.

This article interrogates the controversial field of complementary and alternative medicine (CAM), focussing in particular on the implication of the British press in its regulation. It grounds its analysis in a 'decentred' understanding of regulation; a socio-legal approach which moves beyond formal regulation and regulators, and instead foregrounds diverse social actors and their attempts to alter behaviour across a given domain. Focussing on The Times newspaper as a case-study, it identifies five regulatory techniques through which the newspaper drew (and redrew) lines separating the safe from the risky, the efficacious from the sham, and the normal from the deviant. By analytically decentring CAM's formal regulation, this article provides a conceptual contribution. It highlights an everyday form of healthcare regulation directed at prospective users which may be just as significant in potentially guiding users towards or away from particular healthcare practices/practitioners as the more traditional, formal kinds of regulation identified in regulatory literatures.

The effects of mass media messages, perceived susceptibility and self-rated health on public attitude towards COVID-19 in South Africa.

OBJECTIVES: South Africa was the worst affected country in Africa by the COVID-19 pandemic and it is important to interrogate the attitude of the populace towards the pandemic for future interventions. Therefore, this study examined effects of mass media messages, susceptibility to COVID-19 and self-rated health on the attitudes of South Africans towards the COVID-19 pandemic. METHODS: Data was from the National Income Dynamics Study - Coronavirus Rapid Mobile Survey (NIDS-CRAM) of 2021 which is a nationally representative panel survey of about 7,000 South African individuals in all the nine provinces. Analyses of data were through descriptive statistics, chi square test and logistic regression models. RESULTS: The results showed that 61.28% of the resondents did not take COVID-19 test while 91.09% of them engaged in behavioral changes such as social distancing and wearing of face masks. In addition, 74.27% of the respondents had access to mass media information, 70.44% believed they have good physical health while 32.43% felt they were not susceptible to COVID-19. The chi-square results of attitude towards COVID-19 showed significant differences in access to mass media messages on COVID-19, race, and province of residence. Furthermore, respondents who had access to mass media information on COVID-19 (OR = 1.469; p = 0.001) and respondents who believed that they were susceptible to COVID-19 infection (OR = 1.443; p = 0.001) were significantly associated with increased likelihood of engagement in behavioral changes to avoid the COVID-19. CONCLUSION: These findings therefore emphasize the need for increased awareness and sensitization of the people about the susceptibility and adverse effects of diseases to ensure that they adopt the appropriate attitudes that will safeguard them from such diseases outbreak.

Assessing the Outputs, Outcomes, and Impacts of Science Communication: A Quantitative Content Analysis of 128 Science Communication Projects.

Few studies have explored how science communication projects are evaluated and what impact they have. This study aims to fill this gap by analyzing the results of science communication projects carried out by academics. Drawing on the theory of change and evaluation models, possible results of science communication projects are conceptually distinguished at the levels of outputs, outcomes, and impacts. The study draws on a dataset of 128 science communication projects funded by the Swiss National Science Foundation from 2012 to 2022. Quantitative content analysis reveals few rigorous evaluation designs and a focus on reporting outputs, while outcomes and societal impacts are often neglected.

Making sense of drug use and dependence-A scoping review of mass media interventions intended to reduce stigma towards people who use drugs.

BACKGROUND: People who use drugs face entrenched stigma, which fosters shame, restricts service access, and exacerbates inequalities. The use of mass media in anti-stigma interventions offers an opportunity to challenge stigmatising attitudes at scale. There are, however, inconsistencies in messaging approaches used in mass media anti-stigma interventions, and how authors conceptualise and measure 'stigma'. METHODS: This scoping review maps literature on the development and/or evaluation of mass media interventions intended to reduce stigma towards people who use drugs. We systematically searched seven databases for reports about: (i) people who use drugs, (ii) stigma, (iii) mass media. We charted data about intervention (i) subjects and recipients, (ii) format, (iii) authors, (iv) content; and (v) conceptualisation and measurement of stigma. We narratively synthesised findings with qualitative content analyses. RESULTS: From 14,256 records, we included 49 reports about 35 interventions. 25/35 were from the last five years and 19/35 were from the United States. Intended recipients included the public and/or specified sub-populations, often including healthcare workers. Most interventions were intended to reduce stigma towards people with patterns of drug use perceived to be problematic, as opposed to people who use drugs in general. Interventions ranged from single pieces of media to complex multi-format campaigns. People who use(d) drugs contributed to 22/35 interventions. Professionals working in medical disciplines co-authored 29/35 interventions. Intervention content often had a medical focus, describing dependence as a 'disease' or medical issue, and emphasised the benefits of recovery. Other interventions, however, criticised medical framings. In some interventions drug use and people who use drugs were described in markedly negative terms. 'Stigma' was often under-theorised, and measurement approaches were inconsistent, with 42 instruments used to measure phenomena associated with stigma across 19 quantitative evaluations. CONCLUSION: We found inconsistencies in approaches to reduce and measure stigma, potentially reflecting different motivations for intervention development. The primary motivation of many interventions was seemingly to promote drug service engagement and recovery.

Radiologist representation in cinema.

RATIONALE AND OBJECTIVES: There is limited representation of radiologists in the media, which has been proposed to be a factor in the lack of patient awareness towards radiologist. This study is attempt to look into radiology representation in film. MATERIALS AND METHODS: The IMDb website was searched for feature films containing the words "radiologist" and "radiology" in the plot summaries. The resulting titles were reviewed for availability, and if available, for content analysis to demonstrate the representation of radiology. Additional medical specialties were also searched for comparison. RESULTS: Of the 19 titles returned, only 9 were available on major streaming platforms and of those, 7 were available in English or with English subtitles. Among these, due to plot summary writers confusing radiologists with radiology technologists or other non-radiologist physicians, only 3 actually featured radiologists, and one of these was an extremely negative portrayal of radiologists. Only one film featured an accurate portrayal of a radiologist performing the job of a radiologist. CONCLUSIONS: Accurate and positive radiologist representation in film is extremely limited and if public awareness is the goal, conscious effort is needed in this area.

The impact of media-based mental health campaigns on male help-seeking: a systematic review.

More than half of all men do not seek professional help for depression, suicide and anxiety. Although media-based campaigns represent a promising health promotion intervention to improve male help-seeking, it is unclear what communication strategies in extant mental health media-based campaigns are effective for men. The aim of this systematic review was to synthesize information about the effectiveness of these campaigns on male help-seeking outcomes. A search was conducted of electronic databases and gray literature. Studies were eligible if they examined the effectiveness of a media-based campaign targeting male help-seeking attitudes, beliefs, intentions or behaviors in relation to mental disorders, distress, suicide or self-harm. Twenty-two studies of varying quality met the eligibility criteria. Most studies targeting mental health or depression were found to positively influence male help-seeking. There were mixed results for suicide prevention campaigns. Some evidence suggests that overall, brochure-based campaigns impact help-seeking. The use of male or mixed-gender campaign imagery produced similar results. The choice of message framing appeared to influence help-seeking outcomes. Despite substantial heterogeneity in campaign approaches and difficulties isolating the effects of campaign delivery from messaging, the review indicates that media-based campaigns can play a role in improving male help-seeking for mental health difficulties. Mounting evidence suggests that messaging and delivery should align with male communication preferences. However, high-quality, targeted research is required to evaluate the circumstances in which various campaign delivery and messaging components are effective in improving male help-seeking for poor mental health and suicidality.

Inequalities in Complementary Feeding Programs in Randomized Intervention and Nonintervention Areas after Program Implementation in Bangladesh, Ethiopia, and Vietnam.

Background: Children in the 6-23-mo age group need to consume adequate energy and nutrients for healthy growth, brain development, cognition, and future productivity. Yet, large deficits remain. Complementary feeding practices can be improved on a large scale, but whether interventions reach and benefit disadvantaged mothers is not known. Objectives: To assess inequalities in complementary feeding practices and coverage following large-scale program implementation in 3 low- and middle-income countries. Methods: We re-analyzed evaluation data from randomized controlled studies conducted in Bangladesh, Ethiopia, and Vietnam and calculated socioeconomic inequality using Erreygers index for intervention and nonintervention areas. Intervention coverage indicators were developed in each country for interpersonal communication, community mobilization, agricultural extension, and media. We compared the direction and magnitude of inequalities in intervention and nonintervention areas. Results: At the endline, coverage, and practices related to complementary feeding were better in intervention areas, but coverage and practices favored the better-off and more educated mothers. In Bangladesh, only 5, and in Vietnam, only 1 out of 16 coverage variables measured favored disadvantaged mothers or were neutral; in Ethiopia, out of 18 coverage variables measured, 11 favored disadvantaged mothers or were neutral, and in all 3 countries, only 5-6 variables out of 16 that were measured favored disadvantaged mothers or were neutral. Conclusions: Inequalities exist both in how children in the 6-23-mo age group are fed and in programs aimed at improving complementary feeding practices. Programs favor the better-off and more educated mothers. We need to better understand context-specific program barriers and tailor targeted interventions to reach disadvantaged mothers.

Are Anti-Tobacco Messages Delivered through Different Mass-Media Channels Effective in India? Results from GATS-II Survey.

BACKGROUND: Anti-tobacco mass-media campaigns are an integral part of tobacco control. There is still a need to understand which mode of mass-media channels aids in promoting tobacco cessation. This study aimed to examine if exposure to anti-tobacco messages delivered through different media channels is associated with tobacco user's thoughts and attempts to quit. METHODS: We selected a sample of tobacco users (N=21857) from the Global Adult Tobacco Survey (GATS-2), and assessed the association of noticing the anti-tobacco information through different media channels with tobacco user's thoughts and attempts to quit. RESULTS: Males reported noticing anti-tobacco information more than females in almost all modes of media channels. Among males, the odds were significant and were highest with exposure to radio (1.78 (1.4-2.27)), and internet (1.68 (1.12-2.52)) for thoughts to quit smoking and to radio (2.17 (1.63-2.89) and newspaper (1.46 (1.2-1.79) for thoughts to quitting smokeless tobacco (SLT). The attempt to quit smoking and SLT use among males was significant for exposure through public transportation (1.22 (1.03-1.44)), public walls (1.44 (1.21-1.71), internet (1.68 (1.06-2.66)), and radio (1.44 (1.1-1.87)). Exposure to more than two media resulted in a higher likelihood of thoughts of quitting tobacco, and those exposed to more than one media attempted to quit tobacco among males. Females reported no influence from the media exposure. CONCLUSION: The study underscores the importance of targeted and combination of different mass-media channels to maximize the quit behaviors among male tobacco users. The current study also highlights the need for future studies to identify effective ways to communicate anti-tobacco information to women and all socio-economic groups in the country.

Inequalities in large-scale breastfeeding programmes in Bangladesh, Burkina Faso and Vietnam.

Inequalities in breastfeeding programmes and practices have slowed global progress in providing the life-saving protection of breastfeeding for millions of infants despite well-known life-long impacts. As breastfeeding interventions are scaled up, inequalities in coverage and breastfeeding practices should be tracked, particularly in disadvantaged groups, who are likely to suffer the most serious health and developmental impacts of poor childhood nutrition. The literature provides evidence of inequalities in breastfeeding practices, but research is limited on socioeconomic disparities in the coverage of breastfeeding interventions. This paper (1) compares inequalities in breastfeeding practices in intervention and nonintervention areas and (2) documents inequalities in programme coverage by type of intervention. We disaggregated endline evaluation surveys in Bangladesh, Burkina Faso and Vietnam, where rigorous evaluations had documented significant overall improvements, and analysed whether inequalities in breastfeeding practices and programme coverage differed by treatment areas. We used Erreygers index to quantify inequalities and found that breastfeeding practices were largely pro-poor; intervention coverage was not consistently pro-poor. While counselling coverage often favoured women from the poorest quintile, public education/media coverage consistently favoured better-off women. Inequalities favoured more educated mothers in the coverage of combined interventions. None of the programmes had explicit equality objectives. The results indicate the need for introducing specific actions to reduce inequalities in breastfeeding policies and programmes. This is a priority unfinished agenda for nutrition programming.

Factors associated with dental clinic use by clients in Nigeria during the COVID-19 pandemic.

BACKGROUND: Nigeria, like many other countries, faced challenges in dental care provision during the COVID-19 pandemic, necessitating limited care to emergencies only. However, the impact of restricted access to dental services on oral health remains a concern, particularly with preventive maintenance care. This study aims to identify the factors associated with dental service utilization during the COVID-19 pandemic among patients attending dental clinics in Nigeria, and their sources of information about COVID-19. METHODS: This cross-sectional study recruited 500 participants who had visited dental clinics before and during the pandemic. Data were collected through telephone interviews and online questionnaires between September and December 2021. Inferential analyses were conducted using ordered logistic regression models to assess the association between the independent (awareness of emergency dental treatments, knowledge of COVID-19 transmission routes in dentistry, awareness of required preparations in dental practice settings, fear of COVID-19 infection in dental settings), and dependent (utilization of dental services during the pandemic) variables after adjusting for confounding variables (age, sex, educational status, COVID-19 vaccinations status and COVID-19 status of live-in residents). The sources of COVID-19 information by dental patients was also identified. Statistical significance was established at 95% confidence level with a p value < 0.05. RESULTS: Many participants were males (51.2%) and had tertiary education (61.6%). Fear of COVID-19 infection in dental settings was significantly associated with lower odds of utilizing dental care services during the pandemic (Adjusted Odds Ratio: -0.06, 95% Confidence Interval: -0.08, -0.01). The main sources of COVID-19 information were mass media and social networks, with only 42% receiving information from dental professionals. CONCLUSION: Fear of COVID-19 infection in dental settings significantly influenced dental service utilization during the pandemic. Strategies to address fear and improve communication channels between dental professionals and patients are essential for promoting oral health during similar crises.

"Dressed like boys, hair trimmed, a nalla kutti otherwise": construction of queer suicide in Indian online news media.

Suicide is a significant newsworthy event, and the media often cover cases involving queer individuals. However, there is a notable lack of research on the quality of reporting of queer suicide cases within the Indian context. This article aims to address the existing gap in Indian online news media by investigating the portrayal of queer suicide via content analysis. Content analysis involves qualitatively condensing and interpreting data to extract key consistencies and meanings from a plethora of qualitative material. The newspapers considered span from 2005 to 2022, with data collection conducted in 2023. The author alone identified news articles on queer suicide and conducted the subsequent content analysis. The study reveals that reporting on queer suicide tends to divide queer couples into the gender binary and describes what it deems to be careless sexual conduct driven by obsessive queer love, which, in turn, is blamed for the suicide. Moreover, these reports often do the following: feature families who refuse to accept their children's identities, adopt dread-filled tones, and cite experts who provide incorrect information while engaging in victim blaming. As a result, the quality of queer suicide reporting in Indian newspapers is deemed substandard and offensive. To address this issue, the study proposes the need for training and curriculum updates in journalistic courses. This way, reporters can develop the skills necessary to sensitively and respectfully report on queer individuals in general and on queer suicide in particular.

Collective memories and social roles: the case of the Paris terrorist attacks of 13 November 2015.

The present study was based on empirical data collected during the first phase (2016) of Study 1000, part of the 13-November Program: a corpus of 934 individual interviews conducted 6-11 months after the events. To process this empirical material, the authors used integrated TXM software, which provides several classic textometry tools. They mainly used the lexical specificity analysis tool, which statistically measures the irregularity of the word distribution according to the parts of the corpus. They also analyzed the concordances of certain very specific lexical forms. Analysis revealed the important influence of social roles on the construction of memories and narratives of this event. Application of textometry tools highlighted lexical fields specific to the different social roles played by the interviewees in this social drama, and showed that it was through these specific vocabularies that they remembered and recounted this extraordinary story. Social roles therefore influence the formation of memories both individual and collective, by modulating the way in which individuals select what to remember and what to forget. The article opens up several interesting avenues for future analyses, mainly a longitudinal perspective (including phases 2 and 3 of Study 1000) for the study of flashbulb memories and the gender issue to fine-tune the analysis of social roles.

Neutrality and impartiality in Midwestern U.S. newspapers: community-oriented newspaper journalists reporting of environmental water problems in agricultural and ranching states.

BACKGROUND: U.S. journalists embedded in rural and agricultural communities could adversely affect the health of residents if they avoid alerting and engaging their readers - farmers, ranchers, and community members - on environmental and health issues. We expected reporters would maintain community status quo and inaction by framing local water pollution and quality issues neutrally deemphasizing threats and solutions to maintain their own credibility as unbiased informational sources. METHOD: In a content analysis of local water quality newspaper articles from five farming and cattle ranching states in the west central U.S. Midwest, we employed seven variables to investigate whether journalists practiced neutral, detached forms of journalism (i.e. dissemination versus interpretative role enactment, government-frame) as well as whether they deemphasized water pollution as a concerning issue (i.e. problem, threat), water pollution solutions, and readers' efficaciousness. RESULTS: The results showed these journalists relied heavily on government-driven narratives presenting water quality issues from an impartial, straight reporting lens in which they primarily followed the journalistic dissemination role enactment, while neglecting to provide readers with interpretative, threat, efficacy, or solution's information. CONCLUSIONS: The study seeks to help communicators understand the information diet people living in this part of the country likely receive on environmental and health risks in the context of water pollution. Communicators seeking to reach and affect audiences in this region should understand local information practices to navigate how to craft culturally specific public health messages.

Dementia Knowledge in Chinese Newspapers (2005-2020): A Topic Modeling Analysis.

How public policies convey dementia is an important source of the public's understanding of dementia, and newspapers are critical to depicting and disseminating this information to the public. The present study used topic modeling strategies to analyze Chinese newspaper portrayals of dementia from 2005 to 2020 to trace changes in key areas of dementia knowledge in relevant policies. Using WiseNews, the largest Chinese media database, we chose 45 newspapers from mainland China and identified 12,719 articles related to dementia. Using latent Dirichlet allocation (LDA), we performed a topic modeling analysis and identified the six most prevalent topics on dementia across articles: lifestyle recommendations, neighborhood life, foundational scientific research, celebrity and media portrayals, dementia caregiving, and pharmaceutical innovations - all related to the dementia knowledge scale's four dimensions. Findings suggest a steady increase in the number of articles on dementia caregiving and a decline in lifestyle recommendations from 2005 to 2020. However, newspapers continued to stigmatize aging by regularly co-depicting dementia and old age and by using biased terminology. Among the first to investigate dementia's portrayals in mainland Chinese newspapers, this study illuminates the need for expanding mass media campaigns to raise the country's dementia knowledge to foster a dementia-inclusive society.

Using a novel 'difference-in-differences' method and syndromic surveillance to estimate the change in local healthcare utilisation during periods of media reporting in the early stages of the COVID-19 pandemic in England.

OBJECTIVES: Syndromic surveillance supplements traditional laboratory reporting for infectious diseases monitoring. Prior to widespread COVID-19 community surveillance, syndromic surveillance was one of several systems providing real-time information on changes in healthcare-seeking behaviour. The study objective was to identify changes in healthcare utilisation during periods of high local media reporting in England using 'difference-in-differences' (DiD). STUDY DESIGN: A retrospective observational study was conducted using five media events in January-February 2020 in England on four routinely monitored syndromic surveillance indicators. METHODS: Dates 'exposed' to a media event were estimated using Google Trends internet search intensity data (terms = 'coronavirus' and local authority [LA]). We constructed a negative-binomial regression model for each indicator and event time period to estimate a direct effect. RESULTS: We estimated a four-fold increase in telehealth 'cough' calls and a 1.4-fold increase in emergency department (ED) attendances for acute respiratory illness in Brighton and Hove, when a so-called 'superspreading event' in this location was reported in local and national media. Significant decreases were observed in the Buxton (telehealth and ED attendance) and Wirral (ED attendance) areas during media reports of a returnee from an outbreak abroad and a quarantine site opening in the area respectively. CONCLUSIONS: We used a novel approach to directly estimate changes in syndromic surveillance reporting during the early phase of the COVID-19 pandemic in England, providing contextual information on the interpretation of changes in health indicators. With careful consideration of event timings, DiD is useful in producing real-time estimates on specific indicators for informing public health action.
