RESUMEN

BACKGROUND: Public health strategies to improve patient adherence to antibiotics rely mostly on raising awareness of the threat of antimicrobial resistance (AMR) and improving knowledge about antibiotics. We aimed to evaluate how adherence to antibiotics relates to knowledge and the threat perceptions proposed by the Protection Motivation Theory (PMT). METHOD: A cross-sectional online survey was conducted in September-December 2020 with 1002 participants aged 21-70 years in Singapore. Two items, which were reverse coded, evaluated adherence to antibiotics: 'how often do you obtain antibiotics that were left over from the previous prescription' and 'how often did you treat yourself with antibiotics in the past year'. Questions about the PMT-related constructs, and knowledge regarding antibiotics and AMR knowledge were also included. Hierarchical regression models were performed at a 5% significance level. RESULTS: Adherence to antibiotics was associated with knowledge level (ß = 0.073, p < 0.05), education level (ß = - 0.076, p < 0.01), and four of the five PMT constructs: "perceived response cost" (ß = 0.61, p < 0.01), "perceived response efficacy of adherence to antibiotic" (ß = 0.096, p < 0.01), "perceived susceptibility to AMR" (ß = 0.097, p < 0.01), and "perceived severity of AMR" (ß = - 0.069, p < 0.01). Knowledge about AMR, perceived self-efficacy in adhering to antibiotics, age, and sex were not associated with adherence. CONCLUSIONS: In Singapore, patient adherence to antibiotics appear to be driven by the perceived costs of visiting a doctor to obtain antibiotics, followed by perceptions of AMR as a threat and to a lesser extent, knowledge about antibiotics. Public health strategies to mitigate antibiotic misuse should consider these patient barriers to medical care.

RESUMEN

Public health crises like the ongoing COVID-19 pandemic appear to be the perfect breeding ground for misinformation. As influential information sources, mainstream news media have a unique opportunity to use their platform to debunk and educate the public about misinformation. Despite evidence lending support to the potential for mainstream news media to play a larger role in combating misinformation in society, empirical explorations of how they have contributed to the management of misinformation remain scant. This study aims to address these major gaps in research by investigating how mainstream news dailies gatekeep and correct COVID-19 related misinformation in Singapore. The content of 164 news articles published by the mainstream news dailies in Singapore from January 1 to April 30, 2020 on COVID-19 misinformation was analyzed qualitatively and quantitatively. Results show that the two main types of misinformation, fabricated and reconfigured misinformation, were covered almost equally by mainstream news media. Misinformation related to science and health were most frequently reported, followed by scams, and government policy. Statistically significant differences were found between how mainstream news media corrected the various types and topics of misinformation. Significant differences were also found within the various types, topics, and corrections of misinformation across the early stages of the pandemic. Taken together, these findings shed light on the critical role of mainstream news media as public education tools to correct misinformation during public health crises. From a theoretical perspective, these findings contribute to the understanding of media misinformation gatekeeping, and misinformation correction. From a practical perspective, it highlights the capacity and potential roles of the press in supporting government efforts to combat misinformation.

RESUMEN

BACKGROUND: The first wave of COVID-19 during April to July 2020 in Singapore largely affected the migrant workers living in residential dormitories. A government taskforce working with dormitory operators, employers and non-government agencies came together to deliver behavioral interventions and health care services for migrant worker as dorms were imposed movement restrictions. To fill the research gap in understanding movement restriction experiences of migrant workers, this research seeks to describe dormitory contexts and explore behavior change related to both prevention of transmission as well as healthcare seeking for COVID-19 among male migrant workers. METHODS: With social constructivism as the foundation for this study, 23 telephone interviews were conducted with Bangladeshi and Indian migrant workers. A theory-informed, data-driven conceptual framework, characterized by the "Four Ss": Sensitization, Surveillance, Self-preservation, and Segregation was first generated and later used to frame second-stage, more in-depth, thematic analyses. An effective multipronged approach was documented, persuading migrant workers in our case-study to improve hygiene and follow some safe distancing measures, and adhere to help-seeking when symptomatic. RESULTS: Rapid collective adaptation was demonstrated; it was propped up by effective harnessing of infrastructure and technology. While technology and digital platforms were central to shaping Sensitization for prevention-related behaviors, interpersonal communication, especially peer-sharing, was key to normalizing and accepting healthcare delivery and norms about healthcare seeking. Interpersonal factors particularly supported successful implementation of case-detection Surveillance, stimulating Self-preserving and acceptance of rules, and was found helpful to those Segregated in recovery facilities. In contrast, encouraging prevention-related behaviors relied more heavily on multiple online-platforms, phone-based e-learning/knowledge testing, e-monitoring of behavior, as well as interpersonal exchanges. CONCLUSION: Overall, the findings showed that the conception of the Four Ss helped inform intervention strategies. Anchoring these towards optimal use of technology and harnessing of interpersonal communication for prevention and promotion of healthcare seeking in the planning of future Infectious Disease outbreaks in closed institutional settings is recommended.

RESUMEN

OBJECTIVE: To evaluate how public perceptions and trust in government communications affected the adoption of protective behaviour in Singapore during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: We launched our community-based cohort to assess public perceptions of infectious disease outbreaks in mid-2019. After the first case of COVID-19 was reported in Singapore on 23 January, we launched a series of seven COVID-19 surveys to both existing and regularly enrolled new participants every 2 weeks. As well as sociodemographic properties of the participants, we recorded changing responses to judge awareness of the situation, trust in various information sources and perceived risk. We used multivariable logistic regression models to evaluate associations with perceptions of risk and self-reported adopted frequencies of protective behaviour. FINDINGS: Our cohort of 633 participants provided 2857 unique responses during the seven COVID-19 surveys. Most agreed or strongly agreed that information from official government sources (99.1%; 528/533) and Singapore-based news agencies (97.9%; 522/533) was trustworthy. Trust in government communication was significantly associated with higher perceived threat (odds ratio, OR: 2.2; 95% confidence interval, CI: 1.6-3.0), but inversely associated with perceived risk of infection (OR: 0.6; 95% CI: 0.4-0.8) or risk of death if infected (OR: 0.6; 95% CI: 0.4-0.9). Trust in government communication was also associated with a greater likelihood of adopting protective behaviour. CONCLUSION: Our findings show that trust is a vital commodity when managing an evolving outbreak. Our repeated surveys provided real-time feedback, allowing an improved understanding of the interplay between perceptions, trust and behaviour.

RESUMEN

This research aims to better understand cultural disparities in cancer prevention behaviors. To do this, we investigate how four cultural beliefs - optimism, pessimism, naïve dialecticism, and superstition - associate with cancer fatalism, which has been recognized as a major barrier to cancer prevention behaviors. Based on an online survey of 1,021 Singapore residents, the results reveal that cancer fatalism is positively associated with pessimism, naïve dialecticism and superstitions, and associated negatively with optimism. Mediation analyses further reveal that cancer fatalism is a significant mediator between these four cultural beliefs and four cancer prevention behaviors including fruit and vegetable intake, regular exercise, avoidance of smoking, and sunscreen use. This study offers theoretical insights into the understanding of how people develop cancer fatalism and practical guidance on the promotion of cancer prevention behaviors, particularly among Asian populations.

RESUMEN

Parents are important sources of influence in the development of healthy eating among children and adolescents. Besides gatekeeping and modeling, parents serve as health educators and promoters, using intentional and persuasive communication to encourage healthier eating preferences and behaviors in children. Despite this, a lack of reliable and valid measures has limited the research on how parent-driven interpersonal communication about foods influence child food consumption outcomes. Building on the research in parental mediation of media consumption, and parenting practices in public health nutrition, this study details the development and validation of the active and restrictive parental guidance questionnaire with a sample of 246 children and adolescents at the scale development phase and another sample of 1,113 children and adolescents at the scale validation phase. Findings show that parents employ four communicative strategies to encourage a healthier diet: active guidance, general discussion, preventive restrictive guidance, and promotive restrictive guidance. The new measure was shown to have good validity and measurement model fit. Implications for future research are discussed.

RESUMEN

One major gap in existing health communication research is that few studies have synthesized findings from the literature to map out what are the key factors related to workplace (a) safety awareness, (b) safety risks, (c) health awareness, and (d) health risks. This study bridges the gap by systematically reviewing what these organizational, cultural, and individual-level factors are, and examine the impact of workplace safety and health publications using traditional and alternative metrics in academic and non-academic settings. Through an iterative process of coding, the results revealed six categories of organizational (management commitment, management support, organizational safety communication, safety management systems, physical work environment, and organizational environment), two cultural (interpersonal support and organizational culture), and four individual-level (perception, motivation, attitude, and behavior) factors. In terms of impact, articles that were most impactful in academia (e.g., high citation count) may not necessarily receive the same amount of online attention from the public. Theoretical and practical implications for health communication were discussed.

RESUMEN

Objectives. To evaluate the effectiveness of point-of-care informational interventions in general practitioner clinics to improve influenza and pneumococcal vaccination uptake among elderly patients.Methods. We conducted a pragmatic, cluster-randomized crossover trial in 22 private general practitioner clinics in Singapore, from November 2017 to July 2018. We included all patients aged 65 years or older. Clinics were assigned to a 3-month intervention (flyers and posters encouraging vaccination) plus 1-month washout period, and a 4-month control period (usual care). Primary outcomes were differences in vaccination uptake rates between periods. Secondary outcomes were identification of other factors associated with vaccination uptake.Results. A total of 4378 and 4459 patients were included in the intervention and control periods, respectively. Both influenza (5.9% vs 4.8%; P = .047) and pneumococcal (5.7% vs 3.7%; P = .001) vaccination uptake rates were higher during the intervention period compared with the control period. On multilevel logistic regression analysis, follow-up for hypertension, diabetes mellitus, hyperlipidemia, or any combination of the 3 was associated with uptake of both vaccines.Conclusions. Point-of-care informational interventions likely contributed to increased influenza and pneumococcal vaccination uptake. Patients on follow-up for hypertension, diabetes mellitus, hyperlipidemia, or any combination of the 3 were more likely to receive influenza and pneumococcal vaccination and should be actively engaged by physicians.Trial Registration. ClinicalTrials.gov Identifier: NCT03445117.

RESUMEN

The study of parenting practices on child food consumption has often been characterized as having great utility but lacking in theory. In contrast, the theory of planned behavior (TPB) has often been suggested to be limited in its utility. To address these gaps, interpersonal constructs - the concepts of active parental guidance (e.g., nutrition education) and restrictive parental guidance (e.g., rule-setting) - were integrated as antecedents to the original TPB variables in predicting child fruits and vegetables (FV) consumption. We surveyed 210 child/adolescent participants, aged between 10 and 16 in Singapore. Results from structural equation modeling showed that the integrative TPB model displayed an acceptable fit. Parental active guidance was associated with all three proximal predictors of behavior. Our results suggest that there are promising contributions to the theory of planned behavior in predicting child food consumption behavior by considering interpersonal antecedents.

RESUMEN

BACKGROUND: Dengue is a serious problem around the globe, with 3.9 billion people at risk of the disease. Sri Lanka has recently seen unprecedented rates of dengue with 4.3 times more cases than during the same period over the previous six years. The paper discusses the development of an integrated health systems framework, aided by mobile technology, to combat and contain dengue via a health hackathon in Sri Lanka. RESULTS: The framework addresses the key functions of surveillance, health communication and civic engagement through innovations including digitisation of hospital forms; digital aid to Public Health Inspectors (PHIs); data consolidation and analytics; education for construction workers, GPs, and schools; and educating the general public. CONCLUSIONS: We present the impact of the disease burden in tropical countries, such as Sri Lanka, current technological solutions, and the process of developing the mobile application modules developed via the health hackathon.

RESUMEN

BACKGROUND: The family is an important social context where children learn and adopt eating behaviors. Specifically, parents play the role of health promoters, role models, and educators in the lives of children, influencing their food cognitions and choices. This study attempts to systematically review empirical studies examining the influence of parents on child food consumption behavior in two contexts: one promotive in nature (e.g., healthy food), and the other preventive in nature (e.g., unhealthy food). METHODS: From a total of 6,448 titles extracted from Web of Science, ERIC, PsycINFO and PubMED, seventy eight studies met the inclusion criteria for a systematic review, while thirty seven articles contained requisite statistical information for meta-analysis. The parental variables extracted include active guidance/education, restrictive guidance/rule-making, availability, accessibility, modeling, pressure to eat, rewarding food consumption, rewarding with verbal praise, and using food as reward. The food consumption behaviors examined include fruits and vegetables consumption, sugar-sweetened beverages, and snack consumption. RESULTS: Results indicate that availability (Healthy: r = .24, p < .001; Unhealthy: r = .34, p < .001) and parental modeling effects (Healthy: r = .32, p < .001; Unhealthy: r = .35, p < .001) show the strongest associations with both healthy and unhealthy food consumption. In addition, the efficacy of some parenting practices might be dependent on the food consumption context and the age of the child. For healthy foods, active guidance/education might be more effective (r = .15, p < .001). For unhealthy foods, restrictive guidance/rule-making might be more effective (r = -.11, p < .01). For children 7 and older, restrictive guidance/rule-making could be more effective in preventing unhealthy eating (r = - .20, p < .05). For children 6 and younger, rewarding with verbal praise can be more effective in promoting healthy eating (r = .26, p < .001) and in preventing unhealthy eating (r = - .08, p < .01). CONCLUSIONS: This study illustrates that a number of parental behaviors are strong correlates of child food consumption behavior. More importantly, this study highlights 3 main areas in parental influence of child food consumption that are understudied: (1) active guidance/education, (2) psychosocial mediators, and (3) moderating influence of general parenting styles.

RESUMEN

This study proposes that parental mediation of television advertising and parental guidance of food consumption differentially influence children's attitude, intention, and behavior toward the consumption of healthy and unhealthy foods. Structural equation modeling based on a survey of 1,119 children aged 9-12 supported our model, revealing that parental education strategies influence children's food consumption in a complex manner that is highly context-dependent. Parental guidance of food consumption enhanced children's healthy food attitude and intention to consume, while reducing the intention to consume unhealthy food. However, parental mediation of television advertising influenced unhealthy food attitude to a greater extent than healthy food attitude. Implications for health promotion and education, as well as parents and policy makers are discussed.

RESUMEN

Although culture is acknowledged as an important factor that influences health, little is known about cultural differences pertaining to cancer-related beliefs and prevention behaviors. This study examines two culturally influenced beliefs-fatalistic beliefs about cancer prevention, and optimistic beliefs about cancer risk-to identify reasons for cultural disparity in the engagement of cancer prevention behaviors. We utilized data from national surveys of European Americans in the United States (Health Information National Trends Survey 4, Cycle3; N = 1,139) and Asians in Singapore (N = 1,200) to make cultural comparisons. The odds of an Asian adhering to prevention recommendations were less than half the odds of a European American, with the exception of smoking avoidance. Compared to European Americans, Asians were more optimistic about their cancer risk both in an absolute and a comparative sense, and held stronger fatalistic beliefs about cancer prevention. Mediation analyses revealed that fatalistic beliefs and absolute risk optimism among Asians partially explain their lower engagement in prevention behaviors, whereas comparative risk optimism increases their likelihood of adhering to prevention behaviors. Our findings underscore the need for developing culturally targeted interventions in communicating cancer causes and prevention.

RESUMEN

This article focuses on a novel social media-based system that addresses dengue prevention through an integration of three components: predictive surveillance, civic engagement and health education. The aim was to conduct a potential receptivity assessment of this system among smartphone users in the city of Colombo, the epicenter of the dengue epidemic in the island country of Sri Lanka. Grounded in Protection Motivation Theory (PMT) and using a convenience sampling approach, the cross-sectional survey assessed perceived severity (PSe), perceived susceptibility (PSu), perceived response efficacy (PRE), perceived self-efficacy (PSE) and intention-to-use (IU) among 513 individuals. The overall receptivity to the system was high with a score of >4.00 on a five-point scale. Participants belonging to younger, better educated and higher income groups reported significantly better perceptions of the efficaciousness of the system, were confident in their ability to use the system, and planned to use it in the future. PMT variables contributed significantly to regression models predicting IU. We concluded that a social media-based system for dengue prevention will be positively received among Colombo residents and a targeted, strategic health communication effort to raise dengue-related threat perceptions will be needed to encourage greater adoption and use of the system.

RESUMEN

Although interventions targeting the health of students in schools are becoming common, few studies have examined how health messages operate at the group level in school environments. This study examines the effects of message-based health interventions (extrinsic vs. intrinsic goal framing) in group environments (exergame competitive vs. exergame noncompetitive) on eliciting attitudes and intentions toward physical activity among children and adolescents. We conducted a 7-week school-based intervention program involving 336 children and 259 adolescents in Singapore in which pre- and post-intervention responses were recorded. Our findings revealed the difference in responses between child and adolescent groups. Children who participated in noncompetitive exergames with extrinsically framed health messages and those who participated in competitive exergames with intrinsically framed health messages demonstrated more favorable attitudes toward physical activity. However, the same effects were absent in our adolescent group. These findings suggest that the integration of exergames into competitive and noncompetitive environments can serve as a gateway to traditional physical activity in schools when strategically combined with intrinsically and extrinsically framed messages. Practical and theoretical implications for schools and health educators are discussed.

RESUMEN

BACKGROUND: Sri Lanka has witnessed a series of dengue epidemics over the past five years, with the western province, home to the political capital of Colombo, bearing more than half of the dengue burden. Existing dengue monitoring prevention programs are exhausted as public health inspectors (PHIs) cope with increasing workloads and paper-based modes of surveillance and education, characterizing a reactive system unable to cope with the enormity of the problem. On the other hand, the unprecedented proliferation and affordability of mobile phones since 2009 and a supportive political climate have thus far remained unexploited for the use of mobile-based interventions for dengue management. OBJECTIVE: To conduct a needs assessment of PHIs in Colombo with respect to their dengue-related tasks and develop a new mobile-based system to address these needs while strengthening existing systems. METHODS: One-on-one in-depth interviews were conducted with 29 PHIs to a) gain a nuanced, in-depth understanding of the current state of surveillance practices, b) understand the logistical, technological and social challenges they confront, and c) identify opportunities for mobile-based interventions. Quantitative analysis included simple descriptive statistics while qualitative analysis comprised textual analysis of 209 pages of transcripts (or nearly 600 minutes of conversations) using grounded theory approaches. RESULTS: Current paper-based data collection practices for dengue surveillance involved a circuitous, time consuming process that could take between 7-10 days to officially report and record a single case. PHIs confronted challenges in terms of unreliable, standalone GIS devices, delays in registering mosquito breeding sites and lack of engagement from communities while delivering dengue education. These findings, in concert with a high motivation to use mobile-based systems, informed the development of Mo-Buzz, a mobile-based system that integrates three components - digitized surveillance, dynamic disease mapping and digitized dengue education - on a common platform. The system was developed through an iterative, evolutionary, collaborative process, consistent with the Spiral model of software development and is currently being used by all 55 PHIs in the CMC system. CONCLUSIONS: Given the entrenched nature of existing paper-based systems in PHIs' work habits, we expect a gradual adoption curve for Mo-Buzz in the future. Equally, we expect variable adoption of the system with respect to its specific components, and specific PHI sub-groups (younger versus older). The Mo-Buzz intervention is a response to multiple calls by the global mHealth community for collaborations in the area of mobile interventions for global health. Our experience revealed that the benefits of this paradigm lies in alleviating country-specific public health challenges through a commonly shared understanding of cultural mores, and sharing of knowledge and technologies. We call upon future researchers to further dissect the applicability of the Spiral Model of software development to mHealth interventions and contribute to the mHealth evidence debate from theoretical and applied perspectives.

RESUMEN

This study examines the effectiveness of incorporating exergaming into physical education lessons as a platform for imparting health education messages and influencing children's beliefs about and attitudes toward physical activity. The authors launched a 6-week intervention program using Nintendo Wii games coupled with protection motivation theory-based health messaging among 5th-grade school children in Singapore. Results indicated that when children who were exposed to threat-framed messages played Wii exergames during physical education lessons, they reported more positive physical activity attitude, self-efficacy, and perceived behavioral control than did those who underwent regular physical education lessons and were exposed to the same message. In addition, among children playing Wii, the threat and coping frames had similar effects on the degree of message influence on physical activity attitudes and beliefs. The implications for schools, parents, and health policy are discussed.

RESUMEN

Food packaging in general and packaging incorporating health messages in particular have been active areas of inquiry, receiving attention from policymakers and food manufacturers alike. This study explores the effects of package seals and claims on perceived product healthfulness as a function of dietary restraint status. A laboratory experiment using realistic three-dimensional packaging shows that for restrained eaters (i.e., those who try to restrict their food intake), nutrition claims on "healthy" products and nutrition seals on "unhealthy" products are effective at enhancing perceptions of product healthfulness. Unrestrained eaters, in contrast, are largely unaffected by nutrition seals and claims. These results provide insights into restrained eaters' purchase motivations, as well as guidance for policymakers seeking to regulate the use of seals and claims.

RESUMEN

BACKGROUND: The use of artificial intelligence (AI) can revolutionize health care, but this raises risk concerns. It is therefore crucial to understand how clinicians trust and accept AI technology. Gastroenterology, by its nature of being an image-based and intervention-heavy specialty, is an area where AI-assisted diagnosis and management can be applied extensively. OBJECTIVE: This study aimed to study how gastroenterologists or gastrointestinal surgeons accept and trust the use of AI in computer-aided detection (CADe), computer-aided characterization (CADx), and computer-aided intervention (CADi) of colorectal polyps in colonoscopy. METHODS: We conducted a web-based questionnaire from November 2022 to January 2023, involving 5 countries or areas in the Asia-Pacific region. The questionnaire included variables such as background and demography of users; intention to use AI, perceived risk; acceptance; and trust in AI-assisted detection, characterization, and intervention. We presented participants with 3 AI scenarios related to colonoscopy and the management of colorectal polyps. These scenarios reflect existing AI applications in colonoscopy, namely the detection of polyps (CADe), characterization of polyps (CADx), and AI-assisted polypectomy (CADi). RESULTS: In total, 165 gastroenterologists and gastrointestinal surgeons responded to a web-based survey using the structured questionnaire designed by experts in medical communications. Participants had a mean age of 44 (SD 9.65) years, were mostly male (n=116, 70.3%), and mostly worked in publicly funded hospitals (n=110, 66.67%). Participants reported relatively high exposure to AI, with 111 (67.27%) reporting having used AI for clinical diagnosis or treatment of digestive diseases. Gastroenterologists are highly interested to use AI in diagnosis but show different levels of reservations in risk prediction and acceptance of AI. Most participants (n=112, 72.72%) also expressed interest to use AI in their future practice. CADe was accepted by 83.03% (n=137) of respondents, CADx was accepted by 78.79% (n=130), and CADi was accepted by 72.12% (n=119). CADe and CADx were trusted by 85.45% (n=141) of respondents and CADi was trusted by 72.12% (n=119). There were no application-specific differences in risk perceptions, but more experienced clinicians gave lesser risk ratings. CONCLUSIONS: Gastroenterologists reported overall high acceptance and trust levels of using AI-assisted colonoscopy in the management of colorectal polyps. However, this level of trust depends on the application scenario. Moreover, the relationship among risk perception, acceptance, and trust in using AI in gastroenterology practice is not straightforward.

RESUMEN

The current study aims to understand the factors that influence adolescents' disclosure of personally identifiable information (PII) on social networking sites (SNSs). A survey was conducted among 780 adolescent participants (between 13 and 18) who were Facebook users. Structural equation modeling was used for analyzing the data and obtaining an overarching model that include cognitive, personality, and social factors that influence adolescents' PII disclosure. Results showed privacy concern as the cognitive factor reduces adolescents' PII disclosure and it serves as a potential mediator for personality and social factors. Amongst personality factors, narcissism was found to directly increase PII disclosure, and social anxiety indirectly decreases PII disclosure by increasing privacy concern. Amongst social factors, active parental mediation decreases PII disclosure directly and indirectly by increasing privacy concern. Restrictive parental mediation decreases PII disclosure only indirectly by increasing privacy concern. Implications of the findings to parents, educators, and policy makers were discussed.
