Knowledge, Awareness, and Perceptions of Genetic Testing Towards Hereditary Diseases among University Students in Lebanon: A Cross- Sectional Study
This cross-sectional study of 339 Lebanese university students reveals high levels of knowledge and positive perceptions regarding genetic testing for hereditary diseases, with prior exposure identified as the strongest determinant of these favorable outcomes.

Genetic testing has quietly become a cornerstone of modern medicine, offering a way to look inside our biological blueprint before symptoms ever appear. It allows doctors to identify inherited conditions, understand a person's susceptibility to certain illnesses, and make informed choices about family planning and treatment. Yet, for these tools to work effectively, the people using them must understand what they are and what they can do. In many parts of the world, a gap exists between the availability of these technologies and the public's ability to navigate them. This is particularly relevant in regions where family ties are close and hereditary disorders are more common, as the decisions made by one generation can ripple through the next. Understanding how young adults view these tests is crucial, as they represent the future parents, patients, and healthcare decision-makers who will shape how genetic medicine is integrated into daily life.
In Lebanon, where consanguineous marriages are relatively common and increase the risk of passing down genetic disorders, researchers set out to measure exactly how well university students understood genetic testing. A team of investigators from Holy Spirit University of Kaslik and the American University of Beirut conducted a study involving 339 students from various universities across the country. They wanted to know if these young adults had heard of genetic testing, whether they understood how it works, and what they thought about its role in society. The researchers asked the students to fill out a detailed online survey that covered their personal background, their knowledge of specific hereditary diseases, and their feelings about the ethics and utility of genetic screening.
The results revealed a population that is surprisingly well-informed. Nearly 78 percent of the students had heard of genetic testing before, and a striking 83 percent demonstrated an adequate level of knowledge about the subject. When asked to identify which common conditions run in families, most students correctly recognized that diabetes, cancer, and color blindness are hereditary, though fewer could name less common conditions like hemophilia. The study found that gender played a significant role in knowledge levels, with female students scoring higher than their male counterparts. However, the single strongest factor determining a student's understanding was simply whether they had heard of the term "genetic testing" before. Those who had prior exposure were far more likely to have a solid grasp of the concepts, while those who had never heard of it struggled significantly.
Beyond raw facts, the students held generally positive and pragmatic views about the technology. They largely agreed that genetic testing is important and that its primary value lies in preventing disease rather than just treating it. There was strong support for using these tests on newborn babies and pregnant women to catch health issues early. The students also recognized that while knowing one's genetic risks can improve quality of life and help people live longer, not all genetic disorders can be cured. Interestingly, the group remained cautious about the commercial side of the industry; most believed that genetic tests should only be performed in hospitals with a doctor's prescription and strongly opposed the idea of buying them over the internet or in retail stores. They viewed the technology as a serious medical tool that requires professional oversight.
Despite their positive outlook, the students were not entirely without hesitation. When asked if genetic testing interferes with nature or goes against religious beliefs, a large portion of the group chose to remain neutral, neither agreeing nor disagreeing. This suggests that while they see the medical benefits, they are still weighing the deeper philosophical and ethical questions. The researchers noted that the students themselves identified a lack of public education as the main source of ethical concerns surrounding genetic testing. Consequently, the group strongly supported the idea that governments need to create laws and policies to ensure these tests are used safely and effectively.
The study concludes that Lebanese university students are ready for the integration of genetic testing into their healthcare landscape, possessing both the knowledge and the favorable attitudes necessary to make informed decisions. However, the researchers emphasize that this readiness is not uniform across the entire population. The findings suggest that expanding educational initiatives and strengthening public health policies are essential steps to ensure that the benefits of genetic medicine reach everyone, not just those who have already encountered the concept. By bridging the gap between awareness and understanding, Lebanon can better prepare its future generations to navigate the complexities of hereditary health.
