Differences in clinical characteristics of rosacea across age groups: A retrospective study of 840 female patients

BackgroundAging remains a common influencing factor for many diseases. Previous studies have shown that age is significantly associated with rosacea among female cases and that the incidence of rosacea increases with age. However, previous studies did not specifically analyze the clinical characteristics of different age groups. ObjectiveThis study aimed to analyze and compare the clinical characteristics of female patients of rosacea among different age groups. MethodsWe conducted a retrospective study of 840 female rosacea subjects and compared cutaneous features, aggravating factors, systemic diseases, and psychological states across age groups. The patients were divided into three groups according to their age at diagnosis: <= 30 years?31-44 years?and >= 45 years. ResultsIn our study, the mean age of subjects was 35.9 +/- 10.23 years. The common symptoms included telangiectasia (82.6%), persistent erythema (82.0%), burning/stinging sensation (89.3%), dry sensation (74.0%), and pruritis (41.9%). Hot temperature (89.9%), emotional changes (67.3%), spicy food (55.6%), and sun exposure (50.7%) were the common aggravating factors. Some patients had comorbidities of systemic disorders (20.4%). Of the patients, 48.8% presented with anxiety and 35.2% with depression. The clinical characteristics were found to be significantly different among the different age groups. Middle-aged and older patients (>= 45 years) were more likely to have more serious persistent erythema and telangiectasia. And these patients were relatively less affected by some of the influencing factors and had more systemic diseases of the digestive system, endocrine metabolic system, and cardiovascular system (p < 0.05). ConclusionWe revealed the impact of age on the characteristics of rosacea, which indicated that the clinical features of rosacea are more complex and more difficult to treat in females over the age of 45.
