Depictions of Firearms and Other Projectile Weapons in Top-Selling Japanese Manga.

Firearm violence is a pressing public health issue in the United States and becoming increasingly so worldwide. This concern has prompted researchers to examine the prevalence of such violence in media entertainment. Japanese manga have a large youth readership in the U.S., yet research on their depictions of firearms is presently lacking. We randomly selected 50 chapters from each of ten top-selling manga series worldwide (N = 500) to identify dialogue, action, and other illustrations involving handguns, rifles, machine guns, other projectile weapons, and bombs. Of the 500 chapters, 129 (25.8%) had at least one depiction of a firearm or other projectile weapon, with 684 instances of characters handling (e.g., carrying, holding, firing, reloading) such a weapon. Of the 384 unique characters so depicted, the vast majority were males (88.3%), adults (92.2%), and "good" characters (73.4%). Manga readers, especially male adolescents and preteens, are frequently exposed to storylines in which one or more characters are using a firearm or other projectile weapon. Working collaboratively, manga publishers and distributors should act to develop and implement a comprehensive rating system to flag content that may be harmful to youth so that parents can more easily monitor what their children are reading.

Evaluation of the population-level impacts of the LiveLighter® obesity prevention campaign from 2012 to 2019 based on serial cross-sectional surveys.

BACKGROUND: Halting and reversing the upward trend in obesity requires sustained implementation of comprehensive, evidence-based strategies at the population-level. The LiveLighter® program targets adults using a range of public education strategies, including mass media campaigns, to support healthy lifestyle changes to attain or maintain a healthy weight and reduce the risk of chronic disease. LiveLighter® has been implemented in Western Australia (WA) since 2012 and, to our knowledge, includes the longest running adult-targeted mass media campaign for healthy weight and lifestyle promotion and education globally. This evaluation assessed the impact of LiveLighter® on WA adults' knowledge, intentions and behaviours as they relate to healthy eating and body weight from 2012 to 2019. METHODS: LiveLighter® mass media campaigns, which are TV-led and aired statewide, depict genuine, graphic imagery of visceral fat around internal organs to raise awareness about the link between excess body weight and chronic diseases; demonstrate how unhealthy food and drink consumption can contribute to unhealthy weight gain; and recommend healthy alternatives. Cross-sectional telephone surveys were conducted at baseline and following each campaign phase with an independent, randomly selected sample of WA adults aged 25 to 49 years (n = 501 to n = 1504 per survey) to assess their knowledge of the link between excess body weight and chronic diseases, and their intentions and behaviours related to healthy eating and weight. Multivariable logistic regression models were undertaken to assess differences in responses between baseline and each post-campaign survey. RESULTS: Compared to baseline, there were significant increases in the proportion of respondents reporting knowledge of excess body weight as a risk factor for certain cancers and type 2 diabetes, intentions to eat more fruit and vegetables and drink less sugar sweetened beverages (SSBs) in the next seven days, and the proportion of respondents who reported meeting guidelines for daily vegetable intake. Reported consumption of SSBs significantly decreased. CONCLUSIONS: LiveLighter® is associated with improvements in knowledge of the health risks associated with excess body mass, increased vegetable intake and reduced SSB consumption in WA adults. These findings support the use of sustained, well-designed healthy lifestyle promotion and education programs as part of a comprehensive obesity prevention strategy.

Exposure to pro-tobacco and anti-tobacco media messages and events and smoking behaviour among adolescents in Gambia.

BACKGROUND: Despite the widespread prevalence of adolescent smoking in Gambia, a West African country, there is limited research exploring the relationships between exposure to pro-tobacco and anti-tobacco media messages and events and smoking behaviour among young people. This study investigates the interplay of these exposures and smoking behaviour among 11-17-year-old adolescents in Gambia. METHODS: Secondary data analysis was conducted using the 2017 Gambia Global Youth and Tobacco Survey (GYTS), which included a total of 9,127 respondents. Descriptive and inferential analyses, including proportions, Pearson's chi-squared tests, and multivariable logistic regression models, were employed to estimate adjusted odds ratios (aOR) with 95% confidence intervals (CI). RESULTS: The final model revealed significant associations between exposure to anti-tobacco media messages and events and smoking behaviour. Adolescents exposed to anti-tobacco media messages had a 29% increased odds of smoking (aOR 1.29,CI = 1.08,1.53) compared to those unexposed, while exposure to anti-tobacco media events showed a 31% increased odds (aOR 1.31,CI = 1.09,1.59) compared to those unexposed. Exposure to pro-tobacco messages, such as witnessing tobacco use on TV (aOR 1.41, CI = 1.17,1.69) and owning objects with tobacco brand logos (aOR 1.49,CI = 1.19,1.86), was associated with higher odds of smoking. Covariates, including sex, age, and exposure to smoking behaviour by significant others, also demonstrated associations with smoking behaviour. Notably, male respondents showed significantly higher odds of smoking (aOR = 4.01,CI = 3.28,4.89) compared to females. Respondents aged 15 years and older had increased odds of smoking (aOR = 1.47,CI = 1.22,1.76) compared to those below 15 years old. Those whose fathers smoke displayed higher odds of smoking (aOR = 1.35, CI = 1.04,1.76) compared to individuals with non-smoking parents. Additionally, those whose closest friends smoke showed remarkably higher odds of smoking (aOR = 2.87,CI = 2.37, 3.48) compared to those without such influence. CONCLUSION: This study underscores the significant impact of exposure to both anti-tobacco and pro-tobacco media messages and events on smoking behaviour among adolescents in Gambia. However, pro-tobacco messages had a greater influence on smoking prevalence than anti-tobacco messages and events. Understanding these associations is crucial for devising effective public health interventions aimed at reducing tobacco use in this population.

Sweden's excess mortality in 2020-2022 and reporting in the media.

AIM: The aim was to scrutinize the report in March 2023 that Sweden's excess mortality was lowest in 2020-2022 compared with other European Union and Nordic countries, a report that received great national and international attention. STUDY DESIGN: Comparison of excess mortality in Sweden and Norway. METHODS: Excess mortality for 2020-2022 was calculated for Sweden and Norway, the country with per-capita excess mortality closest to Sweden's, compared with the average mortality for 2017-2019 in the respective country, following the definitions by Statistics Sweden reported in a daily newspaper. RESULTS: Excess mortality is a measure with low misclassification compared with other pandemic outcome measures. Following the definitions, total excess mortality for the years 2020-2022 was 11,897 individuals in Sweden and 6089 in Norway. However, the distributions of excess mortality across the 3 years strongly differed. In Sweden, 60% of excess mortality was observed in 2020, 8% in 2021 and 32% in 2022. In sharp contrast, 0% of excess mortality was observed in Norway in 2020, 20% in 2021 and 80% in 2022. If the relative distribution of excess mortality in Sweden had been the same as in Norway in 2020-2022, approximately 7000 individuals who died in 2020 would instead have died as excess mortality in 2022, saving approximately 14,000 person-years in Sweden. CONCLUSIONS: The report disregards residual confounding due to the broad definition of the period 2020-2022. Mass media should avoid one-sided reporting.

How individuals' opinions influence society's resistance to epidemics: an agent-based model approach.

BACKGROUND: Protecting public health from infectious diseases often relies on the cooperation of citizens, especially when self-care interventions are the only viable tools for disease mitigation. Accordingly, social aspects related to public opinion have been studied in the context of the recent COVID-19 pandemic. However, a comprehensive understanding of the effects of opinion-related factors on disease spread still requires further exploration. METHODS: We propose an agent-based simulation framework incorporating opinion dynamics within an epidemic model based on the assumption that mass media channels play a leading role in opinion dynamics. The model simulates how opinions about preventive interventions change over time and how these changes affect the cumulative number of cases. We calibrated our simulation model using YouGov survey data and WHO COVID-19 new cases data from 15 different countries. Based on the calibrated models, we examine how different opinion-related factors change the consequences of the epidemic. We track the number of total new infections for analysis. RESULTS: Our results reveal that the initial level of public opinion on preventive interventions has the greatest impact on the cumulative number of cases. Its normalized permutation importance varies between 69.67% and 96.65% in 15 models. The patterns shown in the partial dependence plots indicate that other factors, such as the usage of the pro-intervention channel and the response time of media channels, can also bring about substantial changes in disease dynamics, but only within specific ranges of the dominant factor. CONCLUSIONS: Our results reveal the importance of public opinion on intervention during the early stage of the pandemic in protecting public health. The findings suggest that persuading the public to take actions they may be hesitant about in the early stages of epidemics is very costly because taking early action is critical for mitigating infectious diseases. Other opinion-related factors can also lead to significant changes in epidemics, depending on the average level of public opinion in the initial stage. These findings underscore the importance of media channels and authorities in delivering accurate information and persuading community members to cooperate with public health policies.

Knowledge and Perceptions of the Public VIS-À-VIS Colorectal Cancer Information in Newspapers in Malaysia.

OBJECTIVE: The study examines knowledge and perceptions of colorectal cancer vis-à-vis colorectal cancer information in newspapers in Malaysia. METHODS: A total of 152 respondents filled in a 76-item questionnaire based on the Health Belief Model. Articles on colorectal cancer in three English newspapers in Malaysia from 1 January to 30 June 2022 were analysed. RESULT: A majority of the Malaysian respondents had low experiential knowledge of colorectal cancer, high perceived severity, low perceived susceptibility, and low to moderate susceptibility based on self-reported lifestyle and health conditions. The diet factor puts a majority of respondents at risk but smoking, alcohol drinking, and large intestine problems are risk factors for less than 10% of the group. The respondents believed in the benefits of seeking treatment but they were only marginally positive as to whether quitting smoking and losing weight could reduce colorectal cancer risk. They reported strong response efficacy and self-efficacy but the top barriers were lack of knowledge and cost. The strongest cue to action for their health protective intentions was news about colorectal cancer in newspapers, magazines, television and youtube. There were positive moderate correlations among perceived severity, benefits, response efficacy, self-efficacy, cues to action, and intention. Little salience was given to colorectal cancer in the three English newspapers based on the number of articles (N=10). The high frequency of information on severity, susceptibility, and benefits of lifestyle changes and screening in the newspaper articles are reflected in questionnaire results on better knowledge. Lack of information and cost prevented respondents from seeking screening or treatment, despite attempts by the newspaper articles to address barriers. CONCLUSION: The study suggests a need to heighten cues to action in the mass media and social media by providing information on cost and practical details of colorectal cancer screening and benefits of diet-related risk factors.

Impact of Traditional and New Media on Smoking Intentions and Behaviors: Secondary Analysis of Tasmania's Tobacco Control Mass Media Campaign Program, 2019-2021.

BACKGROUND: Tasmania, the smallest state by population in Australia, has a comprehensive tobacco control mass media campaign program that includes traditional (eg, television) and "new" channels (eg, social media), run by Quit Tasmania. The campaign targets adult smokers, in particular men aged 18-44 years, and people from low socioeconomic areas. OBJECTIVE: This study assesses the impact of the 2019-2021 campaign program on smokers' awareness of the campaign program, use of Quitline, and smoking-related intentions and behaviors. METHODS: We used a tracking survey (conducted 8 times per year, immediately following a burst of campaign activity) to assess campaign recall and recognition, intentions to quit, and behavioral actions taken in response to the campaigns. The sample size was approximately 125 participants at each survey wave, giving a total sample size of 2000 participants over the 2 years. We merged these data with metrics including television target audience rating points, digital and Facebook (Meta) analytics, and Quitline activity data, and conducted regression and time-series modeling. RESULTS: Over the evaluation period, unprompted recall of any Quit Tasmania campaign was 18%, while prompted recognition of the most recent campaign was 50%. Over half (52%) of those who recognized a Quit Tasmania campaign reported that they had performed or considered a quitting-related behavioral action in response to the campaign. In the regression analyses, we found having different creatives within a single campaign burst was associated with higher campaign recall and recognition and an increase in the strength of behavioral actions taken. Higher target audience rating points were associated with higher campaign recall (but not recognition) and an increase in quit intentions, but not an increase in behavioral actions taken. Higher Facebook advertisement reach was associated with lower recall among survey participants, but recognition was higher when digital channels were used. The time-series analyses showed no systematic trends in Quitline activity over the evaluation period, but Quitline activity was higher when Facebook reach and advertisement spending were higher. CONCLUSIONS: Our evaluation suggests that a variety of creatives should be used simultaneously and supports the continued use of traditional broadcast channels, including television. However, the impact of television on awareness and behavior may be weakening. Future campaign evaluations should closely monitor the effectiveness of television as a result. We are also one of the first studies to explicitly examine the impact of digital and social media, finding some evidence that they influence quitting-related outcomes. While this evidence is promising for campaign implementation, future evaluations should consider adopting rigorous methods to further investigate this relationship.

[Analysis of journalistic framing during the Covid-19 pandemic in Colombia's leading newspapers: El Tiempo and El Espectador]. / Análisis del encuadramiento periodístico en tiempos de pandemia de covid-19 en los principales diarios de Colombia: El Tiempo y El Espectador.

This study presents a content analysis of headlines featured on the front pages of Colombia's two most prominent newspapers during the COVID-19 health emergency. The objective was to examine the framing strategies employed by El Tiempo and El Espectador during their journalistic coverage of the initial phase of the pandemic. Criteria for analysis included informational tone, thematic approaches, grammatical structures in the headlines, information sources, coverage scope, and media perspective. Regarding interpretative frameworks, both newspapers predominantly adopted a negative approach towards the crisis and the structural impact the pandemic had on the country, especially within a context marked by uncertainty and tension. Primary themes were associated with economic and social aspects. The most prominent terms in the headlines during this period were linked to the pandemic, Covid-19, and the virus, concepts that consistently maintained a significant presence in the media agenda of the studied outlets.

Se presenta un análisis de contenido de los titulares publicados en las portadas de los dos diarios de mayor tradición en Colombia durante la emergencia sanitaria por covid-19. El objetivo fue analizar el encuadramiento o framing de los periódicos El Tiempo y El Espectador durante el cubrimiento periodístico del primer periodo de la pandemia. Se tomaron como criterios de análisis el tono informativo, los abordajes temáticos, el tipo de estructura gramatical en los titulares, las fuentes de información, la cobertura y la perspectiva mediática. En relación con los marcos de interpretación, los medios privilegiaron un enfoque negativo de la crisis y del impacto estructural que la pandemia desencadenó en el país, sobre todo desde un contexto marcado por la incertidumbre y la tensión. Los principales temas se asociaron a lo económico y social. Los términos que tuvieron mayor visibilidad en los titulares de dicho periodo se asociaron con pandemia, covid-19 y virus, conceptos que transversalmente mantuvieron una marcada presencia en la agenda mediática de los medios objeto de estudio.

A systematic review of second-hand smoking mass media campaigns (2002-2022).

BACKGROUND: Second-hand smoking (SHS) increases the risk of chronic disease in adults and poses a serious health threat to children. Mass media campaigns are instrumental in raising awareness and reducing SHS exposure. There is a need to identify recent SHS mass media campaigns and assess their sustainability in terms of knowledge, attitudes, and behavioural changes. This systematic review summarises the characteristics and outcomes of mass media campaigns on SHS prevention. METHODS: PubMed, Embase, Web of Science, and grey literature were searched in November 2022 for SHS campaigns implemented between 2016 and 2022. The eligibility criteria included campaigns on the dangers or effects of SHS with any target group, dissemination medium, study design, or language. The database search identified 1,413 peer-reviewed titles, of which 82 full-texts were screened, with 14 meeting the eligibility criteria. The grey literature search identified 9,807 sources, of which 61 were included. We extracted data on the campaign characteristics, metrics, and smoking-related outcomes. The JBI critical appraisal tool was used to assess the risk of bias of the included studies. RESULTS: We found 73 SHS campaigns conducted between 2002 and 2022, across 50 countries. The campaigns reached 378 million people. The reported recall rates range from 8 to 76%. Of the 11 studies that reported smoking-related outcomes, 10 reported increased knowledge in understanding SHS risks (73-85%), five reported an increased prevalence of smoke-free homes, and two reported an increase in number of participants persuading others to quit smoking. Two studies reported a decrease in overall smoking, whereas three studies observed a reduction in smoking in the presence of children. CONCLUSION: The available data provide some support for the effectiveness of SHS campaigns in reducing smoking behaviours in homes and around children. However, the certainty of evidence was low due to the lack of a control group and the substantial heterogeneity in the outcomes assessed. Future campaigns need comprehensive evaluation and reporting to reduce publication bias.

Text analysis of billboards and infographic graphics advertising COVID-19 on promoting preventive behaviors and taking vaccination against the coronavirus pandemic and investigating the opinions of the Iranian adult population.

BACKGROUND: Advertising is one of the most important solutions that health centers and medical services around the world use to try to encourage public opinion to create a positive attitude towards preventive measures and vaccination. This study has been done with the aim of text analysis of billboards and infographics related to promoting preventive behaviors and vaccination against the coronavirus pandemic and providing solutions and models for preventive information and advertising in the field of health. METHODS: The study method in this research is a combination of qualitative and content analysis. Data collection was done in a targeted manner. The sample size includes 33 advertising billboards and infographics. Data collection has been done through searching the sites and websites of health networks and medical education centers in Iran, taking pictures of infographics and billboards in public places, and also receiving archive files of pictures from the public relations of health networks and medical services. The data was collected from February 19, 2020 to December 30, 2022 (the time frame of the pandemic and public vaccination program in Iran). The data was analyzed based on the three-dimensional discourse analysis theory of Fairclough. Then, an online survey about promoting preventive behaviors and vaccination against the coronavirus pandemic in the format of billboards and infographics was designed in SurveyMonkey and its link was provided to the audience through virtual networks and other platforms. The age group of people was selected from 18 to 70 years. Considering that the number of participants should be representative of the entire community under investigation, therefore, based on Cochran's formula, the sample size was equal to 350 people. Finally, users' opinions were analyzed using descriptive statistics. The assessment of validity involved experts in infection control and linguistics. The reliability of the measurement, determined through the Cronbach's alpha internal consistency coefficient, yielded a coefficient of 0.968. RESULTS: The results show that among the four linguistic components of words, syntax, coherence and text structure; "live metaphors", "pronoun "we", "collocation and reference", and "attitude markers" have the most impact on the audience. The frequency percentage of the data shows that these language elements have tremendous power in attracting the audience to perform preventive behaviors. The results show that the language reflects the culture, opinions and needs of people in the society. Also, the results show that encouraging people to perform preventive behaviors should be through the integration of medical information with motivational linguistic factors in order to attract the audience more. CONCLUSIONS: It can be concluded that the use of the appropriate pattern of medical advertising discourse and correct communication strategies, will help public participation in the field of epidemic control. The language of effective health education and health communication during an epidemic must be related to the ways of thinking and speaking of ordinary people. Also, words with metaphorical and ironic meanings have a high potential to influence the health performance of people in society and increase public awareness of health communication. Therefore, using them to create a new value system with the aim of controlling and overcoming the consequences of the epidemic is very effective.

Social media literacy: A conceptual framework.

Concerns over the harmful effects of social media have directed public attention to media literacy as a potential remedy. Current conceptions of media literacy are frequently based on mass media, focusing on the analysis of common content and evaluation of the content using common values. This article initiates a new conceptual framework of social media literacy (SoMeLit). Moving away from the mass media-based assumptions of extant approaches, SoMeLit centers on the user's self in social media that is in dynamic causation with their choices of messages and networks. The foci of analysis in SoMeLit, therefore, are one's selections and values that influence and are influenced by the construction of one's reality on social media; and the evolving characteristics of social media platforms that set the boundaries of one's social media reality construction. Implications of the new components and dimensions of SoMeLit for future research, education, and action are discussed.

Process evaluation of the Belgian one-month-without alcohol campaign 'Tournée Minérale': a mixed method approach.

BACKGROUND: The Tournée Minérale campaign [TMC] is a mass media prevention campaign challenging Belgian adults to refrain from alcohol during one month. A process evaluation may help us better understand the effect of TMC and to formulate recommendations for future editions. The current study aimed to examine reach, experiences, perceived effectiveness and maintenance of TMC. METHODS: A mixed method design was used to assess the process, using pre- and post-questionnaires (n = 49.022, 44.5 ± 13.1 years old, 37.0% men) and focus groups (n = 31, 47.3 ± 14.3 years old, 33.3% men). RESULTS: Most campaign materials were considered useful and/or motivating. Facilitators for taking part in TMC were connectedness with other participants, stimulus control (e.g. removing alcohol at home) and a supportive social environment. Most difficulties were encountered with abstaining during social occasions as participants had to change a habit or find alternative non-alcoholic beverages. Participants reported both beneficial (e.g. sleeping better) and adverse effects (e.g. drinking more soft drinks). CONCLUSIONS: Future editions of TMC should try to decrease perceived adverse effects (e.g. by providing attractive non-alcoholic beverages) and can benefit from having a forum where people can share experiences.

Medication safety perceptions in China: Media exposure, healthcare experiences, and trusted information sources.

OBJECTIVE: Amid ongoing medication safety concerns in China and limited research on public perceptions, this study investigates the correlations between media exposure, healthcare experiences, and individuals' perceptions of medication safety. It also examines individuals' reliance on information sources during safety crises. METHODS: A multistage stratified random sampling was employed with the gross sample containing 3090 Chinese adults aged 18-60 years. Data were analyzed using multiple linear regression. RESULTS: Social media exposure was found to negatively correlate with perceptions of current medication safety and its perceived improvement, while exposure to television and print media showed positive correlations. Positive healthcare experiences were associated with improved medication safety perceptions. Among various information sources, healthcare professionals were deemed most trustworthy during medication safety incidents. CONCLUSIONS: Media exposure and personal healthcare experiences significantly shape individuals' perceptions of medication safety in China, with healthcare professionals playing a crucial role in this context. Practiceimplications: Effective health crisis communication in China needs to be multifaceted, integrating traditional media and social media platforms to disseminate accurate information broadly. Additionally, healthcare professionals should be actively involved in crisis communication. Their role as trusted sources can be leveraged to clarify misconceptions, and reassure the public during medication safety incidents.

Hormonal Contraceptive Side Effects and Nonhormonal Alternatives on TikTok: A Content Analysis.

The use of hormonal contraceptives is decreasing in the United States alongside a growing interest in nonhormonal contraceptive options. Social media messaging may be contributing to this trend. TikTok thus offers a novel opportunity to understand how people share information about risks and alternatives for pregnancy prevention. To describe the availability and content of information about hormonal contraceptive side effects and nonhormonal contraceptive options on TikTok, we conducted a content analysis of 100 videos using the hashtags #birthcontrolsideeffects and #nonhormonalcontraception. We found that these videos were popular and often framed hormonal contraceptives and patient-provider interactions negatively, with users frequently discussing discontinuation of hormonal contraception and no plans for uptake of another contraceptive. When uptake of a new contraceptive method is mentioned, creators typically mention a fertility awareness-based method, which requires specialized knowledge to use safely and effectively. The risks and side effects of hormonal options were often overemphasized compared with the possible risks and side effects of nonhormonal options. This framing may suggest opportunities for providers and health educators to reassess how they counsel about contraceptive options. We conclude with recommendations for future research on TikTok and consider the policy implications of these findings.

Association between exposure to tobacco information through mass media, smoking households and secondhand smoke exposure in adolescents: Survey data from South Korea.

INTRODUCTION: To explore the current situation of exposure of Korean adolescents to secondhand smoke (SHS) in households our study aimed to determine the relationship between family member smoking status, exposure to tobacco information through mass media, and household SHS exposure. METHODS: The present study uses pooled data from the Korean adolescent health behavior online survey conducted in 2015, 2018 and 2021, with 157944 participants. The regression models were used to explore the association between the smoking status of households, and exposure to tobacco information through mass media, and household SHS exposure in adolescents, controlling for potential confounding factors. RESULTS: SHS exposure duration of Korean adolescents in households was 0.88 days per week. The households with smokers including the father (ß=1.087; 95% CI: 1.0-1.126), mother (ß=1.461; 95% CI: 1.379- 1.543), siblings (ß=0.545; 95% CI: 0.493-0.597), grandparents (ß=0.224; 95% CI: 0.174-0.272), and other relatives (ß=0.170; 95% CI: 0.126-0.214), showed a positive association with SHS exposure in adolescents within the household. At the same time, information about anti-smoking ads on television (ß= -0.042; 95% CI: -0.069 - -0.015) and public transportation (ß= -0.031; 95% CI: -0.054 - -0.010), showed a negative association with SHS exposure in adolescents. However, broadcasts, online, and newspaper non-smoking ads were not associated with SHS exposure (p>0.05). In addition, regression models revealed that exposure to cigarette advertising in magazines (ß=0.131; 95% CI: 0.097-0.166), networks (ß=0.151; 95% CI: 0.127-0.175), convenience stores (ß=0.061; 95% CI: 0.035-0.087), and supermarkets (ß=0.133; 95% CI: 0.108-0.158) is associated with SHS exposure in adolescents. Finally, our study showed stronger ties between SHS exposure, family smoking, and tobacco ads in girls. The link between maternal smoking, supermarket ads, and adolescent SHS exposure intensified in 2021 compared to 2015. CONCLUSIONS: Family and media were identified as potential factors associated with SHS exposure in adolescents. Therefore, publicity and education regarding household SHS hazards, and smoking bans in media, can be helpful in protecting adolescents from SHS.

The effect of mass media campaigns on oral health knowledge: A systematic review and meta-analysis.

OBJECTIVES: Knowledge and awareness gained from mass media can prepare people for lifestyle changes and impact their health and well-being. Considering the differences in the results of primary studies, we decided to conduct this study to evaluate the effect of mass media campaigns on oral health knowledge as a systematic meta-analysis and review. METHOD: The databases such as the Web of Sciences (ISI), Scopus, PubMed/Medline, and the Cochrane Library were searched systematically until February 2022. Data pooling was performed using a random effects model. The effect sizes were estimated as odds ratios (ORs) with their 95% confidence intervals (CIs). Additional analyses, including sensitivity, subgroup, and publication bias analyses, were also conducted. RESULTS: Our meta-analysis comprised a total number of seven articles. The pooled results indicated significant increases in oral health knowledge among included studies (OR = 1.64, 95% CI: 1.20-2.24, p < 0.001). In subgroup analyses, the effects of mass media campaigns on oral health knowledge remained significant for the studies with follow-up of less than 150 weeks (OR = 1.69, 95% CI: 1.49-1.91) and working-age populations (OR = 1.80, 95% CI: 1.40-2.32) compared to other categories. CONCLUSION: In general, this study showed that mass media campaigns may have positive effects on oral health knowledge, especially in the working-age population; it seems that for improving health knowledge among children, more initiatives are needed. Besides, the effects of these campaigns seem to be time-dependent and higher in shorter follow-up periods.

Appropriately Addressing Too Much Sitting as a Public Health Issue: Content Analysis of Coverage in the Five Major National Japanese Newspapers.

Recent international public health guidelines now address reducing and breaking up time spent sitting (sedentary behavior). Japanese people spend considerable time sitting in workplaces and other contexts. With potential future public health guidelines in Japan, there is the need for greater public awareness of the importance of reducing sedentary time and of practical ways to do so. From the five major Japanese national newspapers, articles on sedentary behavior published between 2000 and 2021 were identified and coded for content analysis, including the main topic of the article, population group, sedentary behavior context or domain, health outcome, and solutions for reducing sedentary time. There were 53 articles identified, with sedentary behavior being the main topic in 22; workers as a population group appeared in 20 articles and workplaces as a domain in 22. More than 70% mentioned health influences, but fewer than 60% mentioned solutions. Further to informing the public about adverse health influences and consequences for workers and workplaces, there is also the need for improved coverage of the broader benefits of reducing sitting time, sedentary behavior among older adults and children, sitting in all aspects of daily life, and, importantly, considering public health guidelines and solutions for reducing prolonged sitting.

Population-level impact of 'The Real Cost' campaign on youth smoking risk perceptions and curiosity, United Sates 2018-2020.

INTRODUCTION: The FDA's 'The Real Cost' tobacco prevention campaign aimed to counter tobacco marketing efforts directed toward children and youths. Our objectives were to explore the associations between exposure to the FDA's campaign and cigarette risk perception among the US adolescent population, and between exposure and cigarette smoking curiosity among adolescents who never smoked cigarettes. METHODS: We analyzed 3 cycles of National Youth Tobacco Survey (NYTS 2018-2020, n=53738). Multivariable logistic regression models were fitted to measure the relationship between campaign exposure and cigarettes risk perception (among all), as well as the relationship between campaign exposure and cigarette curiosity (among cigarette never smokers). RESULTS: Majority of youths have reported exposure to the campaign 63% between 2018-2020. The odds of youths perceiving cigarettes as risky were 1.6 times higher among exposed compared to those not exposed (adjusted odds ratio, AOR=1.60; 95% CI: 1.43-1.79). There were some racial disparities in risk perceptions among Hispanics and Non-Hispanic Blacks across exposure groups. Exposure was associated with higher cigarettes curiosity odds among Hispanic youths who never smoked (AOR=1.26; 95% CI: 1.10-1.44) compared to their Non-Hispanic White peers. CONCLUSIONS: The FDA's 'The Real Cost' campaign had exposure levels deemed essential for population-level perceptions change. Exposure was associated with youths having higher risk perceptions about the negative health outcomes related to cigarette smoking. However, students that never smoked were more curious about smoking with campaign exposure. Therefore, future health communication plans should consider both the potential benefits and possible unintended consequences prior to launching such campaigns.

Exploring Vaccine Hesitancy and Uptake during COVID-19: A Review of PM's Mann Ki Baat Dialogue.

Public health programmes are interlinked and intertwined with communication, advocacy and social mobilisation for their success. The unprecedented situation created by COVID-19 brought a medical emergency all over the world, the like of which was probably not seen after the Spanish Flu outbreak, a century ago. First there seemed no solution in sight when tens of thousands of people lost their lives to the coronavirus in various countries, but when the vaccine arrived, there were, in general, doubts about its efficacy and safety. Indian scenario was not any different. When the government launched the vaccine in a campaign mode in January 2021, it was also battling with misperceptions and vaccine hesitancy.
