Background: Acne vulgaris is a common skin disease that can affect people in any ages. The development of acne have adverse effects on life quality. Psychological disorders increased in these patients and their psycho social activities have been affected. Since few studies have been done regarding illness perception in people with acne in Iran, this study aimed to investigate the association of perception of acne disease and quality of life in central of Iran. Methods: we analyzed 200 patients Acne Vulgaris referred to Khatam-Al Anbia in 2013-14 by questionnaire of perception of disease (Brief IPQ) and quality of life (DLQL. the data was analyzed using t-test and Chi-square by SPSS-16. Results: Mean age of patients was 24.3 years and 158 people (79%) were women and 42 people (21 %) were men. Mean quality life score in women was 8.79±5.3 and in men was 8.69±5.18. Most patients had moderate acne and duration of their disease was between 1 to 5 years. 136 people were 18 to 25 years old and 64 persons were higher than 25 years. The mean perception scores in men and women were 51.83 and 53.26 respectively In this study, there was a relation between sex (P=0.03), Acne severity and duration with quality of life score. Conclusion: Women and patients with severe acne and longer duration of symptoms had higher quality life score that had more disorder in life.. There was relation between perception and sex and duration of symptoms.

Background: Excessive exposure to solar ultraviolet (UV) radiation can cause skin cancer. Implementing new technologies and computational algorithms can potentially change the outlook for cancer prevention and facilitate early detection of melanoma, thereby reducing mortality. Mobile technology as a potential provider of health services in delivering health information and conducting interventions, especially in skin fields, where a significant part of diagnosis is based on visual examination, can be important. Evidence showed that constructs of protection motivation theory (PMT) were good predictors of practicing sun protection behaviors in students. This study will investigate whether mobile applications improve safe and healthy behaviors and affect students' reduced UV exposure.Method/design: This randomized controlled trial will be conducted on 320 students in 06/04/2022 in Zahedan. We created mobile applications (Sunshine and Skin Health and WhatsApp apps). Sunshine and Skin Health app allows users to see their changed faces in three stages of adolescence, middle age, and old age based on sun protection behavior. The WhatsApp app has 27 health messages based on PMT theory, eight educational files, and a skin cancer clip that will be sent through WhatsApp during a week. Randomization will be performed using a 1:1 (control: intervention) ratio. The primary endpoint is the group difference in sun-protective behaviors immediately after the intervention. The secondary endpoint is the group difference in sun-protective behaviors at a 3-month follow-up. The data will be analyzed in SPSS.22, and the significance level will be considered 0.05.Discussion: The present study examines the effectiveness of mobile applications in improving sun-protective behaviors. If this intervention enhances sun protection behaviors, it can prevent students' skin damage. Trial registration: This trial was prospectively registered on the Iranian Registry of Clinical Trials on February 8, 2021 (IRCT20200924048825N1).
