| Abstract | Background: Demodex mite is the most common ectoparasite in humans. Demodex infestation or demodicosis often remains asymptomatic, but may be a significant causative agent for many dermatological and ophthalmological conditions. Demodex is found in all parts of the human skin, but the majority are on the face. Demodexbrevis inhabits the bottom of the sebaceous glands. Demodex folliculorum is found in the meibomian glands, eyebrows, and eyelashes, and can cause blepharitis. Both of them feed on oil for nutrition. Objectives: The main purpose of this cross-sectional descriptive research was to study the prevalence of human demodicosis and related risk factors in Ahvaz County, southwestern Iran (2022 - 2023). Methods: A total of 225 men and women referring to the Comprehensive Health Center in East Ahvaz were randomly and voluntarily selected. After completing the questionnaire, sampling from four areas of the face (nose, cheeks, chin, and forehead) was performed using the cellophane tape (CTP) and skin pressurization methods to determine Demodex infestation and evaluate associated risk factors. The results of this research were statistically analyzed using SPSS software version 13 and chi-square and Fisher’s exact tests at a confidence level of 95%. Results: According to the obtained data, Demodex infestation in the participants of the study was 52.7% in men and 47.3% in women, and the total detection rate of Demodex was 57.3%. The prevalence of demodicosis with methods CTP and skin pressurization was 53.8% and 18.2%, respectively. The difference in infestation rates between the two methods was significant. The highest and lowest infestation rates by facial area were in the nose (50.2%) and chin (6.2%), respectively, with a significant difference among facial regions. The study included participants over 20 years of age, with the highest infestation rate among those aged 51 and above (46.5%). A significant difference in infestation rates was observed across age groups. Conclusions: It was concluded that Demodex prevalence increases with age. The CTP is a good sampling method for investigations of demodicosis prevalence. | en |
