Pattern of skin diseases in a university hospital in Jeddah, Saudi Arabia: age and sex distribution

Abstract

BACKGROUND Previous studies have investigated the pattern of dermatological diseases in some regions of Saudi Arabia, but studies on the prevalence of skin diseases in Jeddah are lacking. OBJECTIVES Assess the pattern of skin diseases in Jeddah based on age and sex differences and compare the results with those of previous studies conducted in other regions of Saudi Arabia and the Middle East. DESIGN A cross-sectional prevalence study, retrospective. SETTING Dermatology clinic of King Abdulaziz University hospital. PATIENTS AND METHODS Data obtained from electronic medical records were summarized and analyzed. We only included new patients, who first visited the clinic in 2017. MAIN OUTCOME MEASURES Descriptive epidemiological data and statistical comparisons. SAMPLE SIZE 1244. RESULTS Among 3458 patients who attended the dermatology clinic, 1244 were new patients. There were 365 (29.3%) men and 879 (70.7%) women for a male-to-female ratio of 1:2.4. The mean (SD) age of the total population was 35 (3.8) years. The most common dermatological disease was dermatitis (n=266, 21.4%), followed by acne (n=195, 15.7%) and fungal infection (n=136, 10.9%). Atopic dermatitis was the most prevalent dermatome in children (41.7%), while acne was the most prevalent disease in adults (19.5%). The chi-square test indicated a significant difference between acne and sex ( P =.007), with adult women being more commonly affected (79%) and for alopecia and sex ( P <.001), with women being more commonly affected (91.2%). CONCLUSIONS There are slight differences in the prevalence of dermatological diseases in Jeddah, as shown in this study and other studies from other regions in Saudi Arabia and the Middle East. We recommend initiating awareness campaigns to increase knowledge about skin diseases, particularly in men, and improving dermatology-related training programs for primary health care physicians. A population-based study is warranted to clarify the prevalence of skin diseases in Saudi Arabia. LIMITATIONS The inclusion of patients who visited the dermatology clinic only in 2017 and data collection from only registration records.

“…Another study published in 2019, which included children from six schools in Eastern Saudi Arabia, showed that the prevalence of skin disorders among these children was 23.6%, of which 11 (11.3%) had allergic dermatoses and 14 (11.8%) had eczema [26]. Another singlecenter study in Jeddah showed that 41.7% of the children attending the University's dermatology clinic in 2017 had AD [27]. On the other hand, a cross-sectional study involving 1,337 male children in Al Hassa reported a total of 47 (3.5%) children affected by eczematous lesions [28].…”
