Prevalence and factors associated with willingness to use oral fluid based HIV self testing among university students in Dodoma region Tanzania
This study of 384 university students in Dodoma, Tanzania, found that while only 5.7% had previously used oral fluid-based HIV self-testing, a significant majority (72.4%) expressed willingness to adopt it in the future due to its convenience and privacy, despite barriers such as low availability, lack of awareness, and the need for counseling.

HIV remains a persistent global health challenge, a virus that attacks the body's immune system and, without treatment, can lead to severe illness and death. For decades, the standard way to know if someone has the virus has been to visit a clinic, where a nurse draws a small amount of blood to test. While this method is reliable, it often requires people to travel to a facility, wait in line, and face the possibility of being seen by others, which can create fear and stigma. To overcome these barriers, health experts have developed HIV self-testing kits that allow individuals to test themselves in private. There are two main types of these kits: one that uses a tiny drop of blood from a finger prick, and another that uses a swab to collect fluid from the mouth, avoiding needles entirely. The goal of expanding access to these tools is to help more people, especially young adults, learn their status early so they can start treatment if needed, which is crucial for stopping the spread of the virus and keeping people healthy.
In the Dodoma region of Tanzania, researchers set out to understand how university students feel about these self-testing options, with a specific focus on the oral fluid method. They wanted to know how many students had already tried these tests, how many were willing to try them in the future, and what factors might encourage or discourage them. The team gathered a group of 384 students from two universities in the area, asking them to fill out a questionnaire about their lives, their sexual habits, and their thoughts on testing. The students were selected through a simple, random process in their classrooms to ensure a fair mix of participants from different years of study and different fields of learning.
The results revealed a clear gap between what students had done and what they were willing to do. Only a small fraction of the students, about 5.7 percent, had ever used an oral fluid-based HIV self-test. In contrast, roughly 34 percent had used the blood-based version. Despite this low history of use, the mood was surprisingly positive for the future. Nearly three-quarters of the students, or about 72.4 percent, said they would be willing to use the oral fluid test if it were available to them. The researchers found that the main reasons for this willingness were the convenience of the kit, the desire for privacy regarding test results, and a strong fear of needles. Many students simply preferred not to prick their fingers.
However, the study also uncovered significant hurdles that kept students from using these tests in the past. The most common barriers were a lack of availability of the kits, a general lack of awareness about how to use them correctly, and the feeling that they needed professional counseling or support while testing, which they did not have. When the researchers looked deeper into the data, they found that a student's willingness to use the oral test was strongly linked to their personal experiences. Students who had ever had sex were far more likely to say they would use the test than those who had not. Similarly, those who had recently experienced a sexually transmitted disease or who had not used a condom during their last sexual encounter were more inclined to want the test. Interestingly, students who believed the oral test results were accurate were much more likely to be willing to use the method, as were those who had previously received education on how to use the kit.
The study did not find that age, gender, or religion played a significant role in a student's decision to use the test. Instead, the decision seemed to hinge on personal risk perception and practical knowledge. The researchers noted that while the students were eager to use the tool, the current system was failing to provide it. The low usage rates were not because students rejected the idea, but because the services were not accessible and the instructions were not clear. The authors concluded that to increase the use of these life-saving tools, universities and health organizations need to work together to make the kits easier to find, provide clear instructions on how to use them, and offer support systems that respect the student's need for privacy. By addressing these specific gaps, the hope is that more young people will feel empowered to know their status and protect their health.
