Perceptions of COVID-19 and HIV Risk and Related Preventive Health Behaviors in Rural Zambia.

Abstract

Risk perception, its relationship to preventive health behaviors and other factors (e.g., direct experience of a disease) are important for determining effective targets for disease prevention. Whether these relationships are the same for various diseases has not been well-researched. Drawing on a holistic model of risk perception, this study compares levels of perceived risk for COVID-19 and HIV in a rural Zambian community, examines hypothesized correlates of perceived risk, and evaluates whether higher perceived risk and/or its correlates are associated with practicing preventive behaviors for each disease. The sample included 118 adults participating in a larger study of families affected by HIV. Via surveys, information about risk perception, preventive behaviors, knowledge about, trust in information sources, direct experience and hearing about each disease, and prosociality, were collected. For each disease, perceived risk was not related to its preventive behaviors. Levels of perceived risk for COVID-19 and HIV differed significantly, as did their correlates. Having trusted sources of information about HIV was related to higher perceived risk of HIV. Direct experience of COVID-19 was related to higher perceived risk of COVID-19, but only at a level of interest. Although practicing preventive behaviors for each condition was related to higher levels of knowledge about each disease at a level of interest, willingness to engage in behavior beneficial to others (prosociality) was significantly related only to COVID-19 preventive behaviors. Different diseases provoke different levels of perceived risk and engagement with preventive behaviors and may be correlated with distinct factors. These differences may be due to history of experience with a disease, as well as cultural factors.
