The aim of this study was to identify factors associated comprehensive HIV knowledge among reproductive-age women in Gambia.
Age of the women was significantly associated with comprehensive HIV knowledge. Older age women were more likely to have comprehensive HIV knowledge than younger ages. This finding is in line with the studies done in Sub-Saharan Africa, Uganda, India and Nigeria (10,16,18,19). This might be due to older women are matured and they may search information about their health. The other possible reason might be older women might feel free to visit a health facility to get information about their general health condition and they might understand their susceptibility to diseases as well as the dysfunctional outcomes associated with it (21).
Marital status was significantly associated with comprehensive HIV knowledge. Married women were less likely to have comprehensive HIV knowledge than single women. This result is consistent with the studies done in Ghana, and Ethiopia (9,17). The possible reason might be that married women might believe that marriage is protective of HIV/AIDS and may not seek information about HIV transmission as well as prevention methods (16).
Local geographic area was significantly associated with comprehensive HIV knowledge. Women who reside in Kerewan and Janjanbureh regions of Gambia were more likely to have comprehensive HIV knowledge than those who reside in Banjul region. In contrary with this, women who reside in Basse were less likely to have comprehensive HIV knowledge as compared with Banjul. The possible reason might be that there may be spatial differences in access and availability of media or other information system about HIV. There may also be inter and intra-regional socio-cultural variation which may either impede or facilitate HIV knowledge. The other possible reason might be that there may be educational level differences and differences in wealth quintile which may in turn results in variation of comprehensive HIV knowledge across and with in regions of Gambia. However, this needs further research of why this regional discrepancy occurs.
Current contraceptive use was significantly associated with comprehensive HIV knowledge. Those women who use contraceptives were more likely to have comprehensive HIV knowledge. This finding is in line with the study done in Ethiopia (20). This might be due to the reason that women who used contraceptive methods might get information about HIV while they are going to the health facility. The other reason might be since condom is one of the HIV and pregnancy preventive method a health professional might advice about the importance of using condom and about HIV prevention as well as transmission in general.
Educational level of the women was significantly associated with comprehensive HIV knowledge. Women with secondary and higher educational level are more likely to have higher comprehensive HIV knowledge than women with no education. This finding is in line with the studies done in Indonesia, Uganda, and Bangladesh (16,22,23). Educated women have decision making power which helps them to seek health information about HIV/AIDS and their health issues in general. They might have autonomy to decide on their health related aspects of life, and could access to health care services easily the other possible reason might be This might due to women attending secondary and higher education may get HIV related information either in the school curricula or in different extra-curricular activities like in different school clubs and education may also help people to be curious about their health as well as to seek information for their health. Educated women may search different information sources like the social media and internet web-sites of various organizations who are working targeted primarily on HIV which may help them to clear out misperceptions there by helping to develop comprehensive knowledge(13,24,25).
Wealth was significantly associated with comprehensive HIV knowledge. Women who were from middle and rich wealth quintiles were more likely to have comprehensive HIV knowledge than those from poor quintiles. This finding is in line with the studies conducted in Vietnam, Ethiopia, and Sub-Saharan Africa(19,20,26). The possible reason might be women from higher wealth quintiles may have access to media and health information.
Media exposure was significantly associated with comprehensive HIV knowledge. Women who had exposed to media were more likely to have higher comprehensive HIV knowledge than their counterparts. This finding is in line with the studies done in Uganda, Ethiopia, and Malawi(13,16,25). Media has a great importance in creating awareness, enhancing knowledge, and changing health behavior of individuals as well as the community at large by delivering health information through the use of various channels (27).
Ever tested for HIV was significantly associated with comprehensive HIV knowledge. Women who had ever tested HIV were more likely to have higher comprehensive HIV knowledge as compared with their counterparts. This finding is in line with the studies done in Kenya, Uganda, Ethiopia, and Vietnam(13,16,26,28). The reason might be women who had tested for HIV may be get HIV counseling services by the health care provider about its transmission as well as preventive methods.
Internet use was significantly associated with comprehensive HIV knowledge. Women who had used internet were more likely to have higher comprehensive HIV knowledge than those who had not used. This finding is in line with the studies done in Nigeria (29). Internet has a substantial impact in providing health information especially in this information era it takes a lion share of information dissemination(30).
Visiting health facility in the last 12 months was significantly associated with comprehensive HIV knowledge. Women who had visited health facility within the last 12 months were more likely to have comprehensive HIV knowledge than those who had not visited. The possible reason might be those who visited health facility may get health education about different health and health related issues during their waiting time. A women visited a health facility for another purpose may get information on HIV at the health facility(7).
Strength
The use of sample weighting to overcome non-proportional sample allocation during the survey is one of the strengths of the study. The other Strength of the current study is the use of a large sample size that can help to increase the statistical power and validity of the study. Utilization of large sample size and nationally representativeness of DHS data helps to generalize to the population of Gambia.
Limitations
The main limitation of the study is that since it is a cross-sectional study the causal relationship between the outcome and independent variables could not be ascertained. Due to the use of secondary data some important variables like socio-cultural factors could not be identified which limits the number of variables to be included in the study. Since data has been collected through self-reporting of the participants there may be a chance of introducing recall bias.
