Background: Lupus erythematosus is a chronic inflammatory autoimmune
disease that affects various body systems and results in a wide range of
clinical symptoms, including photosensitivity. Sun exposure/UV light is a
well-known factor for disease activity. Therefore, photoprotective measures
are used in patients with lupus erythematosus. This study aimed to estimate
the prevalence of sunscreen use, limitations and association with disease flares
among patients with lupus erythematosus at King Fahad University Hospital,
Al Khobar, Saudi Arabia. Methods: A cross-sectional questionnaire-based
study was conducted on patients with lupus erythematosus at King Fahad
University Hospital between January and March 2022. Results: A total of 146
patients with lupus erythematosus participated in the study and the
prevalence of sunscreen use was found to be 46.6% in the week before
completing the survey. The study also showed that patients who were young,
female, married, had a higher education level and had experienced an
increased number of lupus erythematosus flares tended to use sunscreen more
often. On the other hand, the most common barrier to sunscreen use was
finding it inconvenient; 80% of those who found it inconvenient did not use it
in the week prior the questionnaire (p=0.001), followed by those who believed
that sunscreen did not prevent lupus erythematosus flares (74.7%, p=0.002)
and those who found sunscreen to be expensive (63.0%, p=0.014). Conclusion:
This study revealed a low prevalence of sunscreen use among patients with
lupus erythematosus. Therefore, efforts should be done to raise the awareness
of importance of sunscreen use among patients
