Mammography Exemplars in online News Commentary: Prevalence of Exemplars, Effects on Risk Perceptions and Mammography Intentions, and Mechanisms of Action
Multiple prior studies have examined the nature of news coverage of mammography but have neglected comments generated by readers. However, comments on online news stories have been shown to affect readers’ beliefs and behaviors. Understanding the potential effects of user-generated comments and comments with exemplars, in particular, is necessary to fully understand the effects of online mammography news on media consumers.
Study 1 describes the prevalence, content, and representativeness of mammography exemplars in comments on online news about mammography using a content analysis of mammography news articles (n = 71) and comments (n = 5,858) appearing on The New York Times website from November 2009 to December 2014. Study 2 tests the effects of comments on risk perceptions and mammography intentions and mechanisms of these effects using a randomized online experiment with a sample of U.S. women between the ages of 38 and 48.
Of comments on news articles about mammography, 31% included a mammography exemplar. Of those, 41% included a mammogram-detected breast cancer exemplar and 19% included a false-positive mammogram exemplar. Additionally, articles with mammography exemplars were more likely to have comments that included mammography exemplars.
In Study 2, when compared to comments without exemplars, comments with exemplars did not produce effects on mammography intentions or risk perceptions. Compared to comments about false positives, comments about mammogram-detected breast cancer led to higher intentions to have a mammogram in the next two years, lower intentions to wait until age 50 to have a mammogram, and higher breast cancer risk perceptions. Effects were moderated by participant education level, family history of breast cancer, history of prior mammography, and time spent reading the experimental manipulation. Some effects on mammography intentions were mediated by changes in attitude toward waiting until age 50 to have a mammogram.
This study adds to evidence suggesting that comments appearing with news articles have effects on readers. Those who share content online and allow user-generated comments should consider potential effects before allowing comments to be posted
Evaluation of a Health Education Intervention for Rural Preschool and Kindergarten Children in the Southeastern United States: A Cluster Randomized Trial
This research employed a matched-pairs randomized field experiment design to evaluate a classroom-based health education intervention for pre-Kindergarten and Kindergarten children in a rural region of the southeastern United States. Schools were matched on demographic characteristics, then one school from each pair was randomly assigned to the treatment group and one to the delayed treatment group. The intervention included a field trip experience and an integrated curriculum designed to increase knowledge about nutrition, physical activity, and sleep. Staff conducted individual assessments of changes in knowledge with a random sample of children from each classroom (252 children from treatment classrooms; 251 children from delayed treatment classrooms). We used a multilevel linear regression with maximum likelihood estimation to incorporate the effects of clustering at the classroom and school level while examining the effects of the intervention on individual assessment change scores. During the intervention period, an estimated 3,196 children (treatment: 1,348 students in 68 classrooms in 10 schools; delayed treatment: 1,848 students in 86 classrooms in 10 schools) participated in the intervention. Children in the treatment group had significantly larger assessment change scores than children in the delayed treatment group. Findings suggest significant beneficial effects of the intervention on health knowledge
Addressing the Opioid Epidemic: Defining Cooperative Extension\u27s Role
The PReventing Opioid Misuse In the SouthEast (PROMISE) Initiative team conducted a needs assessment to explore Mississippians\u27 perceptions of the emerging issue of opioid misuse and to identify ways Extension professionals can assist in opioid misuse prevention. In this article, we describe the assessment process that included a series of community forums and a statewide electronic survey. Additionally, we explain how we used the assessment findings to define participants\u27 involvement in opioid misuse prevention and to develop messages to be disseminated by Extension professionals. Information presented here may be of use to Extension personnel in other states interested in engaging in opioid misuse prevention
Making COVID-19-Related Decisions: A Qualitative Study of University Students
Background: SARS-Cov-2 (Coronavirus Disease or COVID-19) has impacted society greatly since its arrival to the United States. More specifically, college students have had to modify their behaviors on campus to minimize the spread of the virus.Purpose: The purpose of this study was to identify benefits and barriers to testing, reporting, and quarantining of undergraduate college students attending a large southeastern university.Methods: Undergraduate students were asked to complete an open-ended Qualtrics survey to share their perceived benefits and barriers to engage in behaviors to detect and prevent the spread of COVID-19. Data was analyzed via Grounded Theory techniques to determine codes and subsequent themes related to the probes.Results: Themes emerged in the categories of (a) Influencing Factors, and (b) Outcomes of the Health Behavior with 12 in the former and six in the latter. Emphasis on disclosure of COVID-19 status could be beneficial in preventing the spread of the virus on large college and university campuses.Conclusion: The data collected in this study can be used to inform COVID-19-related policies and health communication campaigns at similar colleges and universities
The Human Phenotype Ontology in 2024: phenotypes around the world.
The Human Phenotype Ontology (HPO) is a widely used resource that comprehensively organizes and defines the phenotypic features of human disease, enabling computational inference and supporting genomic and phenotypic analyses through semantic similarity and machine learning algorithms. The HPO has widespread applications in clinical diagnostics and translational research, including genomic diagnostics, gene-disease discovery, and cohort analytics. In recent years, groups around the world have developed translations of the HPO from English to other languages, and the HPO browser has been internationalized, allowing users to view HPO term labels and in many cases synonyms and definitions in ten languages in addition to English. Since our last report, a total of 2239 new HPO terms and 49235 new HPO annotations were developed, many in collaboration with external groups in the fields of psychiatry, arthrogryposis, immunology and cardiology. The Medical Action Ontology (MAxO) is a new effort to model treatments and other measures taken for clinical management. Finally, the HPO consortium is contributing to efforts to integrate the HPO and the GA4GH Phenopacket Schema into electronic health records (EHRs) with the goal of more standardized and computable integration of rare disease data in EHRs
Efficiently and Effectively Evaluating Public Service Announcements: Additional Evidence for the Utility of Perceived Effectiveness
Do They Really Work? Quantifying Fabric Mask Effectiveness to Improve Public Health Messaging
The purpose of this study is to compare masks (non-medical/fabric, surgical, and N95 respirators) on filtration efficiency, differential pressure, and leakage with the goal of providing evidence to improve public health messaging. Masks were tested on an anthropometric face filtration mount, comparing both sealed and unsealed. Overall, surgical and N95 respirators provided significantly higher filtration efficiency (FE) and differential pressure (dP). Leakage comparisons are one of the most significant factors in mask efficiency. Higher weight and thicker fabric masks had significantly higher filtration efficiency. The findings of this study have important implications for communication and education regarding the use of masks to prevent the spread of COVID-19 and other respiratory illnesses, specifically the differences between sealed and unsealed masks. The type and fabric of facial masks and whether a mask is sealed or unsealed has a significant impact on the effectiveness of a mask. Findings related to differences between sealed and unsealed masks are of critical importance for health care workers. If a mask is not completely sealed around the edges of the wearer, FE for this personal protective equipment is misrepresented and may create a false sense of security. These results can inform efforts to educate health care workers and the public on the importance of proper mask fit
The Impact of a Risk-Based Breast Cancer Screening Decision Aid on Initiation of Mammography Among Younger Women: Report of a Randomized Trial
Background. Guidelines recommend that initiation of breast cancer screening (BCS) among women aged 40 to 49 years include a shared decision-making process. The objective of this study is to evaluate the effect of a breast cancer screening patient decision-aid (BCS-PtDA) on the strength of the relationship between individual risk and the decision to initiate BCS, knowledge, and decisional conflict. Methods. We conducted a randomized clinical trial of a BCS-PtDA that included individual risk estimates compared with usual care. Participants were women 39 to 48 years of age with no previous mammogram. Primary outcomes were strength of association between breast cancer risk and mammography uptake at 12 months, knowledge, and decisional conflict. Results. Of 204 participants, 65% were Black, the median age (interquartile range [IQR]) was 40.0 years (39.0–42.0), and median (IQR) breast cancer lifetime risk was 9.7% (9.2–11.1). Women who received mammography at 12 months had higher breast cancer lifetime risk than women who had not in both intervention (mean, 95% CI): 12.2% (10.8–13.6) versus 10.5% (9.8–11.2), P = 0.04, and control groups: 11.8% (10.4–13.1) versus 9.9% (9.2–10.6), P = 0.02. However, there was no difference between groups in the strength of association between mammography uptake and breast cancer risk ( P = 0.87). Follow-up knowledge (0–5) was greater in the intervention versus control group (mean, 95% CI): 3.84 (3.5–4.2) versus 3.17 (2.8–3.5), P = 0.01. There was no change in decisional conflict score (1–100) between the intervention versus control group (mean, 95% CI): 24.8 (19.5–30.2) versus 32.4 (25.9–39.0), P = 0.07. Conclusions. The BCS-PtDA improved knowledge but did not affect risk-based decision making regarding age of initiation of BCS. These findings indicate the complexity of changing behaviors to incorporate objective risk in the medical decision-making process
