Abstract
Thalassemia is a life-threatening blood disorder that has a high prevalence in Saudi Arabia despite the implementation of mandatory premarital testing and the availability of genetic counseling. This study aimed to assess college students' knowledge of thalassemia. A cross-sectional survey of a random sample of 920 senior students enrolled at King Abdulaziz University was conducted. A self-administered questionnaire was used to collect information about thalassemia and socio-demographic characteristics. Of the 920 students, 445 (48%) had ever heard of thalassemia. Despite the mandatory premarital testing for thalassemia, only 50% of married students stated having heard of the disease. The mean thalassemia knowledge score was 4.4 +/- 2.2 out of a maximum of 12. Knowledge was significantly influenced by university faculty, gender, and education outside of Saudi Arabia. Those who had heard of thalassemia had misconceptions about the disease characteristics and pattern of inheritance such as associating thalassemia with low iron levels. A substantial proportion of the participants had a low knowledge of thalassemia. This lack of awareness requires a reassessment of the goals and success of the premarital testing program, including the genetic counseling services, and also indicates the importance of emphasizing thalassemia in school curricula and promoting and scaling up existing thalassemia campaigns in the region.
