The Health Communication and Informatics Research Branch at the U.S. National Cancer Institute was founded in 1999 in response to increasing evidence demonstrating a link between effective health ...communication and improved cancer-related outcomes and in recognition of the rapid and dramatic technological changes that were transforming health communication at the turn of the 21st century. For the past 25 years, the Health Communication and Informatics Research Branch has been conducting and supporting research at the forefront of emerging cancer communication trends and technologies, making numerous contributions to health communication science, public health, and cancer control practice. In this essay, we provide a brief history of the branch and the context that led to its establishment, discuss contributions made by the branch to health communication research and practice through key projects and initiatives, and conclude by highlighting health communication and informatics research priorities that offer opportunities for significant impact going forward in light of the challenges posed by the current communication environment.
Purpose
To analyze communication-focused grants funded by the National Cancer Institute (NCI) between fiscal years 2013 and 2019 to provide insight into the characteristics of funded projects and ...identify promising areas for future research.
Methods
iSearch, a portfolio analysis tool, was queried to identify communication-related grants funded by NCI. Abstracts and specific aims were coded for key study characteristics. 344 unique competing grants with a substantial communication component were included in the final analysis. SAS version 9.4 was used to calculate code frequencies.
Results
Most communication grants focused on cancer prevention (
n
= 197), with fewer targeting diagnosis, treatment, survivorship, or end-of-life. Tobacco product use was the most frequently addressed topic (
n
= 128). Most grants targeted or measured outcomes at the individual (
n
= 332) or interpersonal level (
n
= 127). Cancer patients/survivors (
n
= 101) and healthcare providers (
n
= 63) were often the population of focus, while caregivers or those at increased risk for cancer received less attention. Studies were often based in healthcare settings (
n
= 125); few studies were based in schools or worksites. Many grants employed randomized controlled trials (
n
= 168), but more novel methods, like optimization trials, were uncommon.
Conclusion
NCI’s support of health communication research covers a diverse array of topics, populations, and methods. However, the current analysis also points to several promising opportunities for future research, including efforts focused on communication at later stages of the cancer control continuum and at multiple levels of influence, as well as studies that take advantage of a greater diversity of settings and leverage novel methodological approaches.
Sharing data from wearable health and activity trackers (wearables) with others may improve the health and behavioral outcomes of wearable users by generating social support and improving their ...ability to manage their health. Investigating individual factors that influence US adults' willingness to share wearable data with different types of individuals may provide insights about the population subgroups that are most or least likely to benefit from wearable interventions. Specifically, it is necessary to identify digital health behaviors potentially associated with willingness to share wearable data given that the use of and engagement with various technologies may broadly influence web-based health information-sharing behaviors.
This study aims to identify sociodemographic, health, and digital health behavior correlates of US adults' willingness to share wearable data with health care providers and family or friends.
Data for the analytic sample (N=1300) were obtained from the 2019 Health Information National Trends Survey of the National Cancer Institute. Digital health behavior measures included frequency of wearable device use, use of smartphones or tablets to help communicate with providers, use of social networking sites to share health information, and participation in a web-based health community. Multivariable logistic regression analysis of weighted data examined the associations between digital health behaviors and willingness to share wearable device data, controlling for sociodemographics and health-related characteristics.
Most US adults reported willingness to share wearable data with providers (81.86%) and with family or friends (69.51%). Those who reported higher health self-efficacy (odds ratio OR 1.97, 95% CI 1.11-3.51), higher level of trust in providers as a source of health information (OR 1.98, 95% CI 1.12-3.49), and higher level of physical activity (OR 2.00, 95% CI 1.21-3.31) had greater odds of willingness to share data with providers. In addition, those with a higher frequency of wearable use (OR 2.15, 95% CI 1.35-3.43) and those who reported use of smartphones or tablets to help communicate with providers (OR 1.99, 95% CI 1.09-3.63) had greater odds of willingness to share data with providers. Only higher level of physical activity was associated with greater odds of willingness to share wearable data with family or friends (OR 1.70, 95% CI 1.02-2.84). Sociodemographic factors were not significantly associated with willingness to share wearable data.
The findings of this study suggest that, among US adult wearable users, behavior-related factors, rather than sociodemographic characteristics, are key drivers of willingness to share health information obtained from wearables with others. Moreover, behavioral correlates of willingness to share wearable data are unique to the type of recipient (ie, providers vs family or friends). Future studies could use these findings to inform the development of interventions that aim to improve the use of patient-generated data from wearable devices in health care settings.
Cells are continually exposed to a range of electromagnetic fields (EMFs), including those from the Schumann resonance to radio waves. The effects of EMFs on cells are diverse and vary based on the ...specific EMF type. Recent research suggests potential therapeutic applications of EMFs for various diseases. In this study, we explored the impact of a physiologically patterned EMF, inspired by the H3 receptor associated with wakefulness, on PC-12 cells in vitro. Our hypothesis posited that the application of this EMF to differentiated PC-12 cells could enhance firing patterns at specific frequencies. Cell electrophysiology was assessed using a novel device, allowing the computation of spectral power density (SPD) scores for frequencies between 1 Hz and 128 Hz. T-tests comparing SPD at certain frequencies (e.g., 29 Hz, 30 Hz, and 79 Hz) between the H3-EMF and control groups showed a significantly higher SPD in the H3 group (p < 0.050). Moreover, at 7.8 Hz and 71 Hz, a significant correlation was observed between predicted and percentages of cells with neurites (R = 0.542). Key findings indicate the efficacy of the new electrophysiology measure for assessing PC-12 cell activity, a significant increase in cellular activity with the H3-receptor-inspired EMF at specific frequencies, and the influence of 7.8 Hz and 71 Hz frequencies on neurite growth. The overall findings support the idea that the electrical frequency profiles of developing cell systems can serve as an indicator of their progression and eventual cellular outcomes.
ObjectivesTo systematically document measurement approaches used in the monitoring and evaluation of gender-based violence (GBV) risk mitigation activities, categorise the types of available ...literature produced by sector, identify existing tools and measures and identify knowledge gaps within the humanitarian sector.DesignSystematic mapping and in-depth review.Data sources: Pubmed, Global Health, PsychInfo, ReliefWeb, OpenGrey (grey literature), Google Scholar, Web of Science (Social Science Index)Eligibility criteria: a structured search strategy was systematically applied to 17 databases as well as registers, websites and other resources to identify materials published between 1 January 2005 and 15 May 2019.Data extraction and synthesis: Those resources that met the inclusion criteria underwent a comprehensive full-text review. A detailed matrix was developed and key data from each resource were extracted to allow for the assessment of patterns in thematic areas.ResultsA total of 2108 documents were screened. Overall, 145 documents and 112 tools were reviewed, representing 10 different humanitarian sectors. While numerous resources exist, many lack sufficient information on how to monitor outputs or outcomes of GBV risk mitigation activities. There is also limited guidance on how to integrate the measurement of GBV risk mitigation into existing monitoring and evaluation frameworks. Those reports that aimed to measure GBV risk mitigation activities mostly employed qualitative methods and few measured the impact of a GBV risk mitigation with robust research designs.ConclusionsRecent efforts to adapt humanitarian response to COVID-19 have highlighted new and existing challenges for GBV risk mitigation. There is a significant gap in the evidence base around the effectiveness of GBV risk mitigation across all sectors. Understanding and strengthening measurement approaches in GBV risk mitigation remains a critical task for humanitarian response.
Early stage diagnosis strongly predicts cancer survival. Recognition of potential symptoms of cancer may improve survival by reducing time to seeking care.
Telephone interviews with a ...population-representative sample of English-speaking adults (aged ≥50 years) in the U.S. (N=1,425) were conducted in 2014 using an instrument adapted from the International Cancer Benchmarking Partnership Awareness and Beliefs about Cancer survey. Anticipated time to seeking care for four cancer symptoms (persistent cough, rectal bleeding, mole changes, and breast changes) was assessed, and delay was defined as waiting >2 weeks. Recognition of symptoms as potential cancer signs was assessed dichotomously. Multivariate logistic regression models were used to assess associations between symptom recognition and anticipated delay, adjusting for demographics, cancer experience, self-reported health, and healthcare access. Analyses were weighted and conducted in 2017.
Symptom recognition varied but was relatively high across all symptoms (76.9%–95.5%). Anticipated delay varied by symptom and was highest for persistent cough (41.2%) and lowest for rectal bleeding (9.1%). For rectal bleeding (AOR=2.65, 95% CI=1.31, 5.36) and mole changes (AOR=3.30, 95% CI=1.48, 7.33), anticipated delay was more likely among individuals who did not recognize the symptom as a warning sign. Adults with lower education levels (p<0.05) and African Americans (p<0.05) were less likely to delay for some symptoms.
Lack of symptom recognition was associated with anticipated delay in seeking care for some cancer symptoms. Differences in recognition and delays by symptom could be driven partly by screening messaging or by ambiguity and functional impact of each symptom.
Background. The use of videos for patient and public health education has been widely adopted and well documented in the literature. Aims. To conduct a systematic review of empirical studies that ...used video-based interventions for cancer prevention and control to document study designs, settings, approaches, targeted cancer sites and behaviors, and outcomes and to identify gaps in research and practice. Method. PubMed, PsychINFO, CINAHL, SCOPUS, and Web of Science were searched for studies published in the 30-year period from 1984 to 2014. Of 1,521 articles identified, duplicates were removed, and titles and abstracts of 779 were examined for eligibility. In all, 315 articles met the inclusion criteria and were coded by three independent coders. Interrater reliability was assessed. Descriptive frequencies and proportions were calculated. Results. Studies evaluating video interventions for cancer prevention and control have increased over time. The majority used randomized controlled trial designs (54%), followed by single-group pre–posttest designs (18%). Most were delivered in health care settings (39%). Detection (30%) and treatment (16%) were the cancer control continuum stages most frequently addressed, with breast cancer (29%) being the most frequently targeted cancer site. The behavior most commonly targeted was screening/early detection (39%). Topics such as caregiving, coping, palliative care, and end of life were rarely addressed. The majority (69%) reported being successful at achieving their stated objectives, though outcomes varied across studies. Conclusions. Video interventions have been widely utilized for cancer prevention and control, with demonstrated successes. Future research should test innovative designs and new delivery platforms and should include underrepresented topics and cancer sites.
Emerging tobacco products have become increasingly popular, and the US Food and Drug Administration extended its authority to all products meeting the definition of a tobacco product in 2016. These ...changes may lead to shifts in public perceptions about tobacco products and regulation, and national surveys are attempting to assess these perceptions at the population level. This article describes the item development and cognitive interviewing of the tobacco product and regulation perception items included in two tobacco-focused cycles of the Health Information National Trends Survey (HINTS-FDA), referred to as HINTS-FDA.
Cognitive interviewing was used to investigate how respondents comprehended and responded to tobacco product and regulation perception items. Adult participants (n = 20) were selected purposively to oversample current tobacco users and were interviewed in two iterative rounds. Weighted descriptive statistics from the fielded HINTS-FDA surveys (N = 5474) were also calculated.
Items were generally interpreted as intended, and participants meaningfully discriminated between tobacco products when assessing addiction perceptions. Response selection issues involved inconsistent reporting among participants with little knowledge or ambivalent opinions about either government regulation or tobacco products and ingredients, which resolved when a "don't know" response option was included in the survey. The fielded survey found that a non-negligible proportion of the population do not have clear perceptions of emerging tobacco products or government regulation.
A "don't know" response option is helpful for items assessing many emerging tobacco products but presents several analytic challenges that should be carefully considered. Multiple items assessing specific tobacco product and regulation perception items are warranted in future surveys.
The findings from this study can serve as a foundation for future surveys that assess constructs related to emerging tobacco products, harm perceptions across multiple tobacco products, and tobacco-related government regulatory activities. The data provide unique insight into item-specific motivation for selecting a "don't know" response option for tobacco survey items.
The National Cancer Institute (NCI) developed the Health Information National Trends Survey (HINTS) to monitor population trends in cancer communication practices, information preferences, health ...risk behaviors, attitudes, and cancer knowledge. The U.S. Food and Drug Administration (FDA) recognized HINTS as a unique data resource for informing its health communication endeavors and partnered with NCI to field HINTS-FDA 2015. HINTS-FDA 2015 was a self-administered paper instrument sent by mail May 29 to September 8, 2015, using a random probability-based sample of U.S. postal addresses stratified by county-level smoking rates, with an oversampling of high and medium-high smoking strata to increase the yield of current smokers responding to the survey. The response rate for HINTS-FDA 2015 was 33% (N = 3,738). The yield of current smokers (n = 495) was lower than expected, but the sampling strategy achieved the goal of obtaining more former smokers (n = 1,132). Public-use HINTS-FDA 2015 data and supporting documentation have been available for download and secondary data analyses since June 2016 at

. NCI and FDA encourage the use of HINTS-FDA for health communication research and practice related to tobacco-related communications, public knowledge, and behaviors as well as beliefs and actions related to medical products and dietary supplements.
Background The Family Smoking Prevention and Tobacco Control Act granted the Food and Drug Administration (FDA) the authority to regulate tobacco products in the U.S. However, little is known about ...how regulation may be related to judgments about tobacco product–related risks. Purpose To understand how FDA tobacco regulation beliefs are associated with judgments about tobacco product–related risks. Methods The Health Information National Trends Survey is a national survey of the U.S. adult population. Data used in this analysis were collected from October 2012 through January 2013 (N=3,630) by mailed questionnaire and analyzed in 2013. Weighted bivariate chi-square analyses were used to assess associations among FDA regulation belief, tobacco harm judgments, sociodemographics, and smoking status. A weighted multinomial logistic regression was conducted where FDA regulation belief was regressed on tobacco product judgments, controlling for sociodemographic variables and smoking status. Results About 41% believed that the FDA regulates tobacco products in the U.S., 23.6% reported the FDA does not, and 35.3% did not know. Chi-square analyses showed that smoking status was significantly related to harm judgments about electronic cigarettes ( p <0.0001). The multinomial logistic regression revealed that uncertainty about FDA regulation was associated with tobacco product harm judgment uncertainty. Conclusions Tobacco product harm perceptions are associated with beliefs about tobacco product regulation by the FDA. These findings suggest the need for increased public awareness and understanding of the role of tobacco product regulation in protecting public health.
