Abstract

Background and aims: Pilgrims with pre-existing Chronic Diseases are at high risk of physical stress that can lead to unexpected health outcomes, including multiple visits to the hospital, organ failure, or even death. In addition, the risk of mortality related to Chronic Diseases increases during mass gatherings due to these same reasons. Therefore, this study aims to evaluate the Prevalence of Chronic Diseases and clinical symptoms among pilgrims during Hajj 2024 in Saudi Arabia.

Methods: During the 2024 Hajj rituals, cross-sectional questionnaires were administered to pilgrims at the Jeddah International Airport. The questionnaire contained questions on sociodemographic information, the presence of Chronic Diseases, types of Chronic Diseases, and clinical symptoms.

Results: A total of 1920 pilgrims were included in the study, with a mean age of 52.03 ± 13.43 and a median of 53 years. Among those, 49.4% were males. The prevalence of Chronic Diseases (CDs) was 36.3% (n = 697). Among those, 16% (n = 308) of them reported hypertension, followed by diabetes 11.6% (n = 222), asthma (4%, n = 76), and cardiovascular diseases (3.4% n = 65). The most common symptoms associated with Chronic Diseases were cough (36.5%, n = 700), followed by fever (21.8%, n = 419), and sore throat (21.2%, n = 407). The presence of diabetes was significantly associated with gender (p = 0.019), while hypertension was more common among male pilgrims (n = 829) compared to female pilgrims (n = 783) (p = 001). Furthermore, the presence of coughing was significantly associated with the age and educational level of the pilgrims (p = 0.001). On the other hand, headaches were more common among females compared to male pilgrims (p = 0.001).

Conclusion: A considerable number of pilgrims suffer from Chronic Diseases, with hypertension being most common. Further interventions, such as education and management before Hajj, are recommended.
