BackgroundThe COVID-19 pandemic has created unprecedented challenges for first responders (eg, police, fire, and emergency medical services) and nonmedical essential workers (eg, workers in food, transportation, and other industries). Health systems may be uniquely suited to support these workers given their medical expertise, and mobile apps can reach local communities despite social distancing requirements. Formal evaluation of real-world mobile app–based interventions is lacking. ObjectiveWe aimed to evaluate the adoption, acceptability, and appropriateness of an academic medical center–sponsored app-based intervention (COVID-19 Guide App) designed to support access of first responders and essential workers to COVID-19 information and testing services. We also sought to better understand the COVID-19–related needs of these workers early in the pandemic. MethodsTo understand overall community adoption, views and download data of the COVID-19 Guide App were described. To understand the adoption, appropriateness, and acceptability of the app and the unmet needs of workers, semistructured qualitative interviews were conducted by telephone, by video, and in person with first responders and essential workers in the San Francisco Bay Area who were recruited through purposive, convenience, and snowball sampling. Interview transcripts and field notes were qualitatively analyzed and presented using an implementation outcomes framework. ResultsFrom its launch in April 2020 to September 2020, the app received 8262 views from unique devices and 6640 downloads (80.4% conversion rate, 0.61% adoption rate across the Bay Area). App acceptability was mixed among the 17 first responders interviewed and high among the 10 essential workers interviewed. Select themes included the need for personalized and accurate information, access to testing, and securing personal safety. First responders faced additional challenges related to interprofessional coordination and a “culture of heroism” that could both protect against and exacerbate health vulnerability. ConclusionsFirst responders and essential workers both reported challenges related to obtaining accurate information, testing services, and other resources. A mobile app intervention has the potential to combat these challenges through the provision of disease-specific information and access to testing services but may be most effective if delivered as part of a larger ecosystem of support. Differentiated interventions that acknowledge and address the divergent needs between first responders and non–first responder essential workers may optimize acceptance and adoption.

Public education campaigns in tobacco control play an important role in changing tobacco-related knowledge, attitudes and behaviors. The Oklahoma Tobacco Stops with Me campaign has been effective in changing attitudes overall and across subpopulations towards secondhand smoke risks.Investigate campaign impact on secondhand smoke policy and risk attitudes.Serial cross-sectional data analyzed with univariate and multivariable models.Random-digit dialing surveys conducted in 2007 and 2015.Oklahomans 18-65 years old.1) Support for smokefree bars; 2) risk assessment of secondhand smoke (very harmful, causes heart disease, causes sudden infant death); and 3) likelihood of protecting yourself from secondhand smoke.With Tobacco Stops with Me exposure, from 2007 to 2015, Oklahomans demonstrated significant increases in: 1) supporting smokefree bars (23.7% to 55%); 2) reporting beliefs that SHS causes heart disease (58.5% to 72.6%), is very harmful (63.8% to 70.6%) and causes sudden infant death (24% to 34%); and 3) reporting they are very likely to ask someone not to smoke nearby (45% to 52%). Controlling for demographics, smokers and males showed reduced attitude change. In uncontrolled comparisons, high-school graduates faired better than non-diploma individuals, who lacked significant attitude changes.Tobacco Stops with Me achieved its mission to more closely align public perception of SHS with well-documented secondhand smoke risks. Efforts to target women were particularly successful. Smokers may be resistant to messaging; closing taglines that reinstate individual choice may help to reduce resistance/reactance (e.g., adding Oklahoma Helpline contact information).

Background: Modern technology (ie, websites and social media) has significantly changed social mores in health information access and delivery. Although mass media campaigns for health intervention have proven effective and cost-effective in changing health behavior at a population scale, this is best studied in traditional media sources (ie, radio and television). Digital health interventions are options that use short message service/text messaging, social media, and internet technology. Although exposure to these products is becoming ubiquitous, electronic health information is novel, incompletely disseminated, and frequently inaccurate, which decreases public trust. Previous research has shown that audience trust in health care providers significantly moderates health outcomes, demographics significantly influence audience trust in electronic media, and preexisting health behaviors such as smoking status significantly moderate audience receptivity to traditional mass media. Therefore, modern health educators must assess audience trust in all sources, both media (traditional and digital) and interpersonal, to balance pros and cons before structuring multicomponent community health interventions. Objective: We aimed to explore current trust and moderators of trust in health information sources given recent changes in digital health information access and delivery to inform design of future health interventions in Oklahoma. Methods: We conducted phone surveys of a cross-sectional sample of 1001 Oklahoma adults (age 18-65 years) in spring 2015 to assess trust in seven media sources: traditional (television and radio), electronic (online and social media), and interpersonal (providers, insurers, and family/friends). We also gathered information on known moderators of trust (sociodemographics and tobacco use status). We modeled log odds of a participant rating a source as “trustworthy” (SAS PROC SURVEYLOGISTIC), with subanalysis for confounders (sociodemographics and tobacco use). Results: Oklahomans showed the highest trust in interpersonal sources: 81% (808/994) reported providers were trustworthy, 55% (550/999) for friends and family, and 48% (485/998) for health insurers. For media sources, 24% of participants (232/989) rated the internet as trustworthy, followed by 21% of participants for television (225/998), 18% for radio (199/988), and only 11% for social media (110/991). Despite this low self-reported trust in social media, 40% (406/991) of participants reported using social media for tobacco-related health information. Trust in health providers did not vary by subpopulation, but sociodemographic variables (gender, income, and education) and tobacco use status significantly moderated trust in other sources. Women were on the whole more trusting than men, trust in media decreased with income, and trust in friends and family decreased with education. Conclusions: Health education interventions should incorporate digital media, particularly when targeting low-income populations. Utilizing health care providers in social media settings could leverage high-trust and low-cost features of providers and social media, respectively. [JMIR Public Health Surveill 2018;4(1):e8]

ObjectivesDescribe tobacco companies' marketing strategies targeting low socioeconomic status (SES) females in the U.S.A.MethodsAnalysis of previously secret tobacco industry documents.ResultsTobacco companies focused marketing on low SES women starting in the late 1970s, including military wives, low-income inner-city minority women, 'discount-susceptible' older female smokers and less-educated young white women. Strategies included distributing discount coupons with food stamps to reach the very poor, discount offers at point-of-sale and via direct mail to keep cigarette prices low, developing new brands for low SES females and promoting luxury images to low SES African-American women. More recently, companies integrated promotional strategies targeting low-income women into marketing plans for established brands.ConclusionsTobacco companies used numerous marketing strategies to reach low SES females in the U.S.A. for at least four decades. Strategies to counteract marketing to low SES women could include (1) counteracting price discounts and direct mail coupons that reduce the price of tobacco products, (2) instituting restrictions on point-of-sale advertising and retail display and (3) creating counteradvertising that builds resistance to psychosocial targeting of low SES women. To achieve health equity, tobacco control efforts are needed to counteract the influence of tobacco industry marketing to low-income women.
