Prevalence and Perception of HPV Vaccination Among Health Science Students in Saudi Arabia.

Objective: This study was carried out to assess the prevalence and perception of human papilloma virus (HPV) vaccination in health science students in Majmaah University, Saudi Arabia. Methodology: A descriptive cross-sectional study was conducted at different health science colleges of Majmaah University on female students. The knowledge of the participants regarding HPV was assessed using a pre-tested questionnaire. The history of vaccination of these female participants was also enquired. Results: More than three-fifth of the participants had heard about HPV. Of these, 83 participants, 59 (71.1%), were aware that it is a disease of women and how to diagnose it. Most participants (86.7%) knew that it can cause cervical cancer, while only 57.8% knew it could be asymptomatic. There were 18% of such participants who thought that HPV and human immunodeficiency virus are the same and that there is no vaccine for the prevention of HPV. Only 14.5% (n = 12) were vaccinated against HPV. Conclusion: A clear gap between knowledge and practice of HPV vaccination was observed, and health education should be planned to educate health professionals to avoid misconceptions.

Regional Prevalence of Hemoglobin C Across Saudi Arabia: An Epidemiological Survey.

INTRODUCTION: HbC is a common structural hemoglobinopathy especially in West Africa. Prevalence and regional distribution of HbC in Saudi Arabia are widely undocumented. Patients with homozygous HbC disease may have mild hemolytic anemia whereas combination with hemoglobin S (HbS) leads to a clinically severe phenotype. AIM: The current epidemiological study, considered the largest from Saudi Arabia, aimed to evaluate the regional prevalence of the HbC variant among the couples participating in the premarital screening program from 2011 to 2018. METHODS: Data from the PMSGC program were obtained for premarital screening and genetic counseling. The collected data were then entered into the SEHA platform, a centralized electronic repository for the 13 designated regions in Saudi Arabia. Hemoglobin electrophoresis samples are analyzed using either HPLC, capillary electrophoresis, or a combination of both methods to confirm the presence of abnormal hemoglobin bands. RESULTS: This study included 1,871,184 individuals from 2011 to 2018. Of those, 49.8% were males and 50.2% were females. 112,618 (6.0%) had an abnormal test. Total number of Hb C cases were 778 (0.04%). HbC trait (HbAC) was detected in 764 participants while homozygous HbC (HbCC) and combined heterozygous (HbSC) were found in 9 and 5 cases, respectively. The regions near the Red Sea have higher rates than the central and eastern regions. CONCLUSION: HbC is a rare variant in Saudi Arabia with varying regional frequencies. HbC variant is more common in Mecca and Madina regions. The geographic area of HbC distribution differs from the areas with high prevalence of HbS, which explains why HbSC disease cases are overwhelmingly rare.
