Aspirin Use among Saudi Adults: The Prevalence and Users' Characteristics

Despite the public routine use of aspirin as cardio-prophylaxis agent, its use is only recommended in particular situations, and not as usual primary prevention. Only few local studies investigate the use of aspirin in patients with certain diseases, but not within the public population. The purpose of this study was to evaluate the prevalence of aspirin use and identify the demographic and clinical characteristics among Saudi users.

A cross-sectional study targeting Saudi adults in Saudi Arabia was conducted over a period of four months in 2021 using online Google forms. The study collected data to assess the prevalence of use, use of aspirin according to prevention type, users' characteristics and comorbidities. Additionally, a self-assessment of knowledge, perception, reasons and attitude towards aspirin use among Saudi adults was conducted. A chi-square test was used to determine the association between the variables. A P-value ≤ 0.05 was considered statistically significant.

The prevalence of aspirin use was 47%. Regarding the self-assessed aspirin knowledge, the majority of the respondents (n = 481; 62.4 %) found to have good knowledge. Less than half of the participants (n = 341; 44%) use aspirin as primary prevention agent while only 23 participants (2.9%) use aspirin as secondary prevention agent. There was a significant difference between gender and user type (p = 0.001). With regards to comorbidities, hypertension, hyperlipidemia, diabetes, and obesity were common among the primary users of aspirin. Significant associations were found (p = 0.001) between participant's user type and the following characteristics such as smoking status, past medical history, presence of comorbidities.

Aspirin use is commonly prevalent Saudi population with good level of knowledge of the therapy; however, its popular use as primary preventive agent for CVD may necessitate medical advice based on the level of cardiovascular risk.
