Participants completed a questionnaire addressing skin color, specific habits, dietary and environmental factors, comorbidities, and assessments of quality of life and depression levels using the Dermatology Life Quality Index (DLQI) and the Patient Health Questionnaire\u20109 (PHQ\u20109), respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The chi\u2010square test was employed to compare the distribution of general characteristics. Univariate analysis was conducted using Pearson's chi\u2010square test. DLQI is a continuous scale analyzed via independent <jats:italic>t<\/jats:italic>\u2010test and PHQ\u20109 is an ordinal scale analyzed via Mann\u2013Whitney <jats:italic>U<\/jats:italic> test. Spearman's rank correlation coefficient was used for nonparametric correlation between two ranked variables. A <jats:italic>p<\/jats:italic> value\u2009&lt;\u20090.05 was considered statistically significant. Chi\u2010square results with OR and 95% CI indicated significant associations between rosacea and factors such as female gender, age, smoking, alcohol consumption, environmental influences (sun exposure, use of cosmetics\/hair products, exercise, exposure to hot weather, hot baths), dietary factors (dairy products, hot coffee consumption), and comorbidities (diabetes mellitus). No significant links were found with skin colors, dietary factors (fatty food, hot and spicy food, hot tea, sweet food), or other comorbidities (hypertension, high cholesterol, <jats:styled-content style=\"fixed-case\"><jats:italic>Helicobacter pylori<\/jats:italic><\/jats:styled-content>, cancer, Crohn's\/ulcerative colitis, dry eye syndrome, chronic kidney disease, and migraine). The rosacea group showed notably higher DLQI scores with moderate effect (9.0%), large effect (40.5%), and extremely large effect (45.5%), along with elevated PHQ\u20109 scores for depression compared to controls, highlighting a significant impact on their quality of life and mental health. Spearman's rank correlation coefficient demonstrated a significantly positive correlation between DLQI and PHQ\u20109 scores among participants (rho\u2009=\u20090.423, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), indicating that greater quality of life impairment is linked to increased depression levels.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These results underscore the complex nature of rosacea and its significant psychosocial burden. Addressing modifiable risk factors (e.g., smoking cessation, avoid alcohol, hot coffee and dairy products intake, sun protection, cessation of cosmetic products) and incorporating (DLQI\/PHQ\u20109 screening) mental health screening and psychological support into treatment could enhance patient outcomes. Further research is necessary to clarify causal mechanisms and improve management strategies, which will aid in preventing and improving rosacea conditions and treatment approaches in the future.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jocd.70337","type":"journal-article","created":{"date-parts":[[2025,7,31]],"date-time":"2025-07-31T10:20:08Z","timestamp":1753957208000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Exploring
