Predicting Chikungunya disease personal protective behaviors: Results of a cross-sectional survey of US-Caribbean travelers

Background: Incidents of vector-borne disease have recently tripled in the United States. Chikungunya disease is a particularly common disease in the Caribbean, posing a threat to international tourists. However, the relationship between psychological variables derived from the protection motivation theory (PMT), and adoption of protective behaviors against the disease, is uncertain. This study sought to identify the psychological predictors of travelers’ protective health behaviors, specifically (1) appropriate clothing use, and (2) indoor spatial repellent use.

Methods: An online, retrospective survey of U.S. international travelers to Caribbean destinations measured the five constructs of the PMT in the context of Chikungunya disease: Perceived severity, perceived vulnerability, perceived response efficacy, perceived self-efficacy, and knowledge. Hierarchical logistic regression analyzed whether these five theoretical constructs predicted the two protective behaviors in respondents who met study criteria (n = 184).

Results: Results suggest that the interaction between chikungunya knowledge and perceived chikungunya severity predicts both appropriate clothing use (odds ratio [OR]: 1.95, CI: 1.18-3.25, P =0.010) and indoor spatial repellent use (OR: 1.55, CI: 1.05-2.29, P =0.029). In the cases of appropriate clothing use, the interaction between perceived chikungunya severity and perceived vulnerability was also a significant predictor (OR: 9.67, CI:1.23-75.80, P =0.031). Additionally, indoor spatial repellent use was also predicted by the interaction of chikungunya knowledge and perceived vulnerability (OR: 1.88, CI:1.18-3.02, P =0.009).

Conclusion : Two-pronged educational approaches may be most efficacious in increasing protective health behaviors. Such efforts could reduce incidents of chikungunya disease and other vectorborne diseases in travel destinations featuring high exposure risks.

Health information seeking behaviour: a concept analysis

BACKGROUND

In 2007, Lambert and Loiselle conducted an extensive concept analysis of the term health information seeking behaviour (HISB) to examine the concept's level of maturity and critically analyse its characteristics. Since their groundbreaking work, HISB has evolved with the proliferation of ICTs. The Internet is now a common and often preferred medium for the pursuit of health information.

OBJECTIVES

The previous analysis spanned 42 years of literature; this article describes an analysis of the last 10 years of literature on HISB and how online seeking has caused the concept to evolve in the literature.

METHODS

This study used the concept analysis methodology employed by Lambert and Loiselle in the original analysis. It also included a systematic search conducted in five databases to identify studies from 2007 to 2017, using similar inclusion criteria from the original study.

RESULTS

Of the more than 500 articles retrieved, 85 journal articles met the inclusion criteria. Consistent with the original work, articles that included outcomes were identified as either behavioural or cognitive.

CONCLUSION

Most of the attention of the works studied focused on individuals and their information source preferences. This HISB analysis can be incorporated with studies to understand how various communities seek information in online versus non-online contexts.

Social Determinants of Health-Related Quality of Life: A Recreation Setting Analysis

Objective. To determine if significant differences between park users and non-park users are associated with scores on a composite health-related quality of life (HRQoL) index. Methods. Data for this study were collected based on random intercept of a cross section of eligible Monroe County, Indiana, residents at four selected public recreational parks, as well as nonpark locations from July to December 2017. Based on data collected using validated survey items, we created a composite HRQoL index. Statistical analysis included independent-samples t test, chi-square cross-tabulation, bivariate regression, and multivariate regression. Results. Frequent park users were significantly different from nonfrequent park users in various respects. The most leisure-time physical activity (LTPA) experiences of frequent park users occurred at a park location. Body mass index and park-based LTPA were significantly positively associated with HRQoL scores in a linear regression model. Conclusion. Frequent park use was shown to be positively associated with increased park-based LTPA and HRQoL. It is therefore possible that increasing park visitation will result in more members of a community who report experiencing their LTPA at a park location. Study outcomes lend support to the validity of a composite HRQoL index for population health assessments.

Mosquito-borne infectious disease, risk-perceptions, and personal protective behavior among U.S. international travelers

Vector-borne diseases account for a significant amount of the global infectious disease burden, including morbidity and mortality. In particular, mosquito-borne infectious diseases (MBIDs) have the greatest burden in number of cases, mortality, and disability-adjusted life years and their prevention and control is critical. However, prevention efforts are hindered by the absence of vaccines and failure of long-term mosquito vector control for these MBIDs. Thus, personal protective behaviors (PPBs) may offer the most promising and effective mode of prevention. This study examines the impact of awareness, perceived susceptibility, and perceived severity for five MBIDs (e.g., Malaria, Dengue, Zika, Chikungunya and West Nile) on the adoption of PPBs. Study participants (n = 1043) were recruited from a probability-based internet panel of adult United States residents with a history of traveling outside of the country in the past year. Data were collected in the U.S. between June 7, 2017 and June 12, 2017. Our findings show that awareness of Zika disease among respondents was consistently associated with adoption of all three PPBs. Respondents that reported high-perceived severity for all five MBIDs were also more likely to report adopting the PPBs of wearing covering clothing and use of mosquito repellent spray. Our findings indicate that U.S. travelers are largely more concerned about Zika, Chikungunya, and Dengue than Malaria and West Nile and that these concerns drive their adoption of the three recommended PPBs. This information should inform the development and design of future public health campaigns for behavior modification to prevent MBIDs.

Awareness and knowledge of Chikungunya infection following its outbreak in Pakistan among health care students and professionals: a nationwide survey

Background

The World Health Organization (WHO) declares Chikungunya (CHIK) infection to be endemic in South Asia. Despite its first outbreak in Pakistan, no documented evidence exists which reveals the knowledge or awareness of healthcare students and workers (HCSW) regarding CHIK, its spread, symptoms, treatment and prevention. Since CHIK is an emergent infection in Pakistan, poor disease knowledge may result in a significant delay in diagnosis and treatment. The current study was aimed to evaluate the awareness and knowledge of CHIK among HCSW.

Methods

A cross-sectional study was conducted among HCSW from teaching institutes and hospitals in seven provinces of Pakistan. We collected information on socio-demographic characteristics of the participants and their knowledge by using a 30-item questionnaire. The cumulative knowledge score (CKS) was calculated by correct answers with maximum score of 22. The relationship between demographics and knowledge score was evaluated by using appropriate statistical methods.

Results

There were 563 respondents; mean age 25.2 ± 5.9 years with female preponderance (62.5%). Of these, 319 (56.7%) were aware of CHIK infection before administering the survey. The average knowledge score was 12.8 ± 4.1 (% knowledge score: 58.2%). Only 31% respondents had good disease knowledge while others had fair (36.4%) and poor (32.6%) knowledge. Out of five knowledge domains, domain III (vector, disease spread and transmission) and V (prevention and treatment) scored lowest among all i.e. percent score 44.5% and 54.1%, respectively. We found that socio-demographic characteristics had no influence on knowledge score of the study participants.

Conclusion

Approximately one-half of participants were not aware of CHIK infection and those who were aware had insufficient disease knowledge. Findings of the current study underscore the dire need of educational interventions not only for health care workers but also for students, irrespective to the discipline of study.
