Abstract

Background/Objectives: Despite the high incidence of sickle cell anemia in Saudi Arabia, little is known about the sociodemographic characteristics, behavioral risk factors, and concomitant conditions of the condition. We performed this study to measure the prevalence of sickle cell anemia and its associated predictors among Saudi residents. Methods: This cross-sectional study was conducted in 48 primary healthcare centers across Saudi Arabia. A total of 14,239 Saudi residents were included through multi-stage random sampling. Data on sociodemographic variables, behavioral factors, and comorbidities were collected using a validated and reliable questionnaire. Univariate and multivariate logistic regression analyses were performed to identify the predictors of sickle cell anemia, with the statistical significance set at a p-value of <0.05. All analyses were carried out using SPSS version 26 for Windows. Results: Overall, the prevalence of sickle cell anemia was found to be 3.2% among Saudi residents. There was a positive association between insurance coverage and sickle cell anemia (AOR: 1.87; 95% CI: 1.52, 2.31). The odds of sickle cell anemia were 1.39 times higher among diabetic than non-diabetic individuals (AOR: 1.39; 95% CI: 1.01, 1.91). There were positive associations between sickle cell anemia and hypertension (AOR: 1.70; 95% CI: 1.23, 2.35), high cholesterol (AOR: 2.38; 95% CI: 1.74, 3.24), and heart disease (AOR: 8.05; 95% CI: 6.05, 10.71). Conclusions: Our findings indicate significant associations between sickle cell anemia and insurance coverage, smoking, obesity, diabetes mellitus, hypertension, hypercholesterolemia, and heart disease. While the overall prevalence of sickle cell anemia in our study was relatively modest, the Saudi Arabian government should prioritize the objective quantification of the disease burden across the population to effectively mitigate its consequences.
