The radical and transformative developments in information and communication technologies (ICTs) offer unprecedented opportunities to promote cancer control and enhance population and individual health. However, the current context in which these technologies are being deployed—where cancer incidence and mortality and communication are characterized by inequalities among different racial/ethnic and socioeconomic status groups—raises important questions for cancer communication research, policy, and practice. Drawing on illustrative data, this essay characterizes the communications revolution and elucidates on its implications for cancer control, with a particular focus on communication inequalities and cancer disparities.
It is known that the level of HIV/AIDS-related knowledge and the degree of condom use varies by socioeconomic status (SES). However, there is limited research on the effect of mass media use on HIV/AIDS-related cognitive and behavioral outcomes in low-income countries and how it might influence the association between SES and HIV-related outcomes. We investigated the moderating effect of media use on the relationship between SES and HIV/AIDS-related knowledge and condom use in sub-Saharan Africa in terms of communication inequalities. Cross-sectional data from the Demographic Health Surveys from 13 sub-Saharan countries (2004–10) were pooled. Gender-stratified multivariable poisson regression of 151,209 women and 68,890 men were used to calculate adjusted relative ratios and 95% confidence intervals for the associations between SES, media use, HIV-related outcomes, and condom use. We found significant disparities in mass media use among people from different SES groups as well as among countries. Education and wealth are strongly and positively associated with awareness of HIV/AIDS and knowledge about transmission and prevention of HIV/AIDS and are significantly associated with condom use. These associations are attenuated when the use of various types of mass media is added to the models, with newspapers showing the strongest effect. The findings of this study suggest that media use has the potential to blunt the impact of socioeconomic status though not completely eliminate it. Thus, we need to pay attention to reducing communication inequalities among social groups and countries to moderate the effect of wealth and SES on HIV/AIDS.
Background:Information seeking may increase cancer survivors' ability to make decisions and cope with the disease, but many also avoid cancer information after diagnosis. The social determinants and subsequent communication barriers that lead to avoidance have not been explored. The purpose of this study is to examine the influence of social determinants on information avoidance among cancer survivors.Methods:We examined how health information avoidance is associated with structural and individual factors in a mail-based survey of 519 cancer survivors. Factor analysis was conducted to determine barriers to obtaining cancer information, and multivariable logistic regression models by gender were run to analyze social determinants of avoidance from an intersectional approach.Results:Participants who were younger, female, had greater debt and lower income, and had difficulty finding suitable information were more likely to avoid information. The probability of information avoidance increased when survivors reported barriers to information use or comprehension.Conclusion:These results indicate that survivors' information avoidance may be driven, in part, by social determinants, particularly among those at the intersection of multiple social status categories. Customized strategies are needed that maximize the likelihood that information will be used by vulnerable groups such as those from a lower socioeconomic position.
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.
