This FHH-based genomics training successfully educated Texas CHWs, and the outcomes were promising. Dissemination of training to CHWs in and outside of Texas is needed to promote better access to and delivery of personalized genomics services for the lay and underserved communities.
Background
Subjective risk perception is an important theoretical construct in the field of cancer prevention and control. Although the relationship between subjective risk perception and health behaviors has been widely studied in many health contexts, the causalities and associations between the risk perception of developing lung cancer and cigarette smoking have been inconsistently reported among studies. Such inconsistency may be from discrepancies between study designs (cross-sectional versus longitudinal designs) and the three hypotheses (i.e., the behavior motivation hypothesis, the risk reappraisals hypothesis, and the accuracy hypothesis) testing different underlying associations between risk perception and cigarette-smoking behaviors. To clarify this issue, as an initial step, we examined the association between absolute and relative risk perceptions of developing lung cancer and cigarette-smoking behaviors among a large, national representative sample of 1,680 U.S. adults by testing an accuracy hypothesis (i.e., people who smoke accurately perceived a higher risk of developing lung cancer).
Methods
Data from the U.S. Health Information National Trends Survey (HINTS) were analyzed using logistic regression and multivariate linear regression to examine the associations between risk perception and cigarette-smoking behaviors among 1,680 U.S. adults.
Results
Findings from this cross-sectional survey suggest that absolute and relative risk perceptions were positively and significantly correlated with having smoked >100 cigarettes during lifetime and the frequency of cigarette smoking. Only absolute risk perception was significantly associated with the number of cigarettes smoked per day among current smokers.
Conclusions
Because both absolute and relative risk perceptions are positively related to most cigarette-smoking behaviors, this study supports the accuracy hypothesis. Moreover, absolute risk perception might be a more sensitive measurement than relative risk perception for perceived lung cancer risk. Longitudinal research is needed in the future to investigate other types of risk perception-risk behavior hypotheses—the behavior motivation and the risk reappraisals hypotheses—among nationally representative samples to further examine the causations between risk perception of obtaining lung cancer and smoking behaviors.
Understanding parents' educational needs concerning genetic testing for their children with autism spectrum disorder (ASD) is important in developing tailored, evidence-based health education materials for clinical use. Since research is lacking in this area, to bridge the gap, we examined genetic testing education needs using a nationwide sample of parents of biological children with ASD in the United States. Prospective participants were recruited from the interactive autism network, and 552 parents of biological children with ASD completed the online survey. Most participants (73.7%) were interested in receiving health education about genetic testing. Yet, the majority of them (64.7%) reported that they did not receive the information needed from physicians. Parents who identified as racial/ethnic minorities (P = 0.029), who had an education degree below college (P = 0.002), or displayed low/no awareness of genetic testing (P = 0.003) were more interested in receiving health education regarding genetic testing. Parents' most desired topics for health education include the accuracy of genetic testing (88.4%), cost (85.9%), relevant benefits of such testing (83.8%), testing procedure (77.8%), eligibility to undergo genetic testing for their children with ASD (62.4%), potential harms caused by genetic testing (56.1%), previous use and experience among individuals affected by ASD (50.8%), and confidentiality issues (48.0%). Furthermore, web-based education was the preferable approach (85.4%). Our findings can help develop health education programs and/or materials regarding genetic testing for parents and physicians to facilitate better physician-parent communication and assist parents in making informed medical decisions regarding genetic testing.Lay Summary: This study examined educational needs on genetic testing among 552 American parents of children with autism spectrum disorder (ASD). Results showed that most parents expressed interests in receiving health education regarding genetic testing (73.7%) and favored online education resources (85.4%). Preferred topics included accuracy, cost, and testing benefits. Our findings can help develop genetic testing related health education programs and materials for parents of children with ASD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
