Frequency of exposure to the media is associated with levels of HIV-related knowledge and stigmatising attitudes among adults in Ghana

Abstract

Studies show that increased knowledge of the human immunodeficiency virus (HIV) is achieved through exposure to mass media, which then contributes to positive attitudes and behaviours towards people living with HIV and acquired immune deficiency syndrome (AIDS). This study examined the relationship between the frequency of exposure to the media and the level of HIV-related knowledge and stigmatising attitudes towards HIV and AIDS among adults in Ghana. A weighted sample of 13 484 men and women 15 to 59 years old took part in the study. The main outcome variable was the HIV-related knowledge score, calculated based on responses to eight questions about general HIV concepts and HIV transmission modes. The frequency of exposure to the media was the primary explanatory variable. The relationship between the frequency of media exposure and the level of HIV-related knowledge was investigated using Poisson regression methods in Stata 13.0. Of the 13 484 respondents analysed, 25%, 88.2% and 79.7% reported reading print media, listening to the radio and watching TV at least once a week respectively. The average HIV-related knowledge score was 4.9 (SD 1.6), with 22.9% of respondents correctly answering five questions and about 2.0% correctly answering all eight questions. The frequency of exposure to the media, particularly print media and television, was associated with an increase in the level of HIV-related knowledge. When compared to having a low level of HIV-related knowledge, having a moderate and high level of HIV-related knowledge reduced the score of stigmatising attitude by 0.065 and 0.277 points, respectively. The adult population in Ghana has a very low level of HIV or AIDS knowledge, as well as a significant level of stigma associated with HIV or AIDS, which could stymie HIV prevention efforts. The media, on the other hand, provide a platform for these issues to be addressed.
