Lifestyle, skincare habits, and dietary habits were collected using a validated questionnaire survey. A Multivariate logistic regression model was employed to analyze risk factors associated with acne vulgaris. Further subgroup analysis and restricted cubic spline function was used to analyze the related risk factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The prevalence of acne vulgaris was 30.33% in 300 rosacea patients, which is significantly higher than the 14.83% observed in the general population. Multivariate logistic regression analysis revealed that sufficient sleep duration was a protective factor against acne vulgaris in rosacea patients [OR\u202f=\u202f0.738 (0.589\u20130.926)] (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05), while the use of sunscreen products was identified as a risk factor [OR\u202f=\u202f2.602 (1.083\u20136.249)], (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05).
