Abstract
Rosacea is a chronic inflammatory skin disease characterized by facial redness and bothersome symptoms. It can exert significant psychological effects and impair the quality of life of patients. To investigate the prevalence and risk predictors of anxiety and depression in rosacea patients, we conducted a cross-sectional study in an outpatient setting. Consecutive patients completed a questionnaire, which included questions on sociodemographic information and severity of signs and symptoms; they also completed the Patient Health Questionnaire and the Generalized Anxiety Disorder scale. Disease burden was assessed using Dermatology Life Quality Index (DLQI), Willing-to-Pay, and Time trade-off. Multivariate analysis was conducted to determine the risk factors for anxiety and depression. A total of 774 patients completed the survey. The prevalence of anxiety was 53.9% (95% CI: 50.4–57.4%) and that of depression was 58.1% (95% CI: 54.7–61.6%). The factors associated with anxiety were age, gender, the need to make appearances at work, severity of self-reported symptoms, the number of rosacea signs and adaptive behaviors, and disease burden. Depression was associated with younger age, more severe self-reported symptoms, more adaptive behaviors, and higher disease burden. After adjusting for demographics, the risk of anxiety or depression increased in young patients who had severe self-reported symptoms, high DLQI scores, and many adaptive behaviors. Taken together, there is a high prevalence of anxiety and depression among Chinese rosacea patients. Younger rosacea patients who have more severe self-reported symptoms and higher disease burden are prone to anxiety and depression.

Introduction
Rosacea is a chronic inflammatory cutaneous disease with an estimated worldwide prevalence of 5.5% (1). In China, the prevalence of rosacea is up to 3.48% (2). Rosacea mostly affects facial areas and is characterized by recurrent flushing, telangiectasia, persistent erythema, phymas, papules, pustules, edema, and irritated eyes (3, 4). In addition to visible signs, patients with rosacea often complain of high levels of discomfort due to the accompanying subjective symptoms, indicating a possible adverse impact on the psychological well-being of the patients. The pathogenesis of rosacea is complex and multifactorial (5); however, it is widely accepted that numerous exogenous factors, including sun exposure, heat, stress, spicy food, and hot beverages, can initiate rosacea (6). In a high proportion of patients, rosacea is triggered or exacerbated by emotional stress, ranking only behind well-known factors such as sun exposure or elevated temperature (7).
Rosacea patients indeed often experience various symptoms of emotional stress, including depression, anxiety, social phobia, low self-esteem, and frustration (8–11). This might result from that rosacea often involves the central parts of the face and affects the patient's appearance; naturally, the patient will likely be constantly concerned with his/her appearance and how it may be misinterpreted by other people. In addition, the recurrent flushing and the accompanying symptoms are so annoying that they negatively influence the patient's emotional health (12). Besides, the current therapies for rosacea are still limited and transiently effective. This decreases the patient's satisfaction and confidence regarding the treatment, and may further aggravate the patient's psychological distress (13). In general, rosacea and psychological distress are intertwined, thus forming a vicious cycle (14, 15).
Rosacea not only has severe physical and mental health effects, but also imposes a heavy burden on the patients. For the assessment of skin diseases, clinicians commonly use measures/tools, such as the Dermatology Life Quality Index (DLQI) (16, 17), Willingness To Pay (WTP) (18), and Time Trade-Off (TTO) (19), to assess the disease burden. To date, research on rosacea has elucidated the effect of rosacea on the quality of life (20) and its economic (21), and psychological burden (22) on affected patients; however, investigations on anxiety and depression and their association with the disease burden of rosacea are limited. Therefore, to improve the management of rosacea, it is important to comprehensively investigate the psychological status of rosacea patients, especially in China.
In this study, we aimed to investigate the prevalence of anxiety and depression among rosacea patients and to identify the possible demographic/clinical characteristics associated with anxiety and depression in rosacea patients. Identification of the predictors for anxiety/depression in rosacea patients may be valuable to clinicians in daily practice.
Patients and Methods
Study Design and Patients
This was a cross-sectional, single center study of 774 rosacea patients conducted at the dermatology outpatient department of Xiangya Hospital of Central South University from May 2018 to August 2019. The inclusion criteria included: (1) patient who visited the hospital for the first time and was independently diagnosed with rosacea by two board-certified dermatologists according to the diagnostic criteria proposed by the National Rosacea Society Expert Committee (3); (2) provision of written informed consent. The exclusion criteria were as follows: (1) patient diagnosed with other concurrent facial skin diseases, such as acne, eczema, systemic lupus erythematosus, seborrheic dermatitis; (2) patient diagnosed with mental illness prior to the occurrence of rosacea; (3) patients who undergo any kinds of trauma that may cause mental illness; (4) patient who had been receiving treatments for rosacea; (5) patient aged <18 years. The study was approved by the ethics committee of the hospital.
Data Collection
The survey consisted of two parts: a self-administered questionnaire and a face-to-face interview. The self-administered questionnaire included questions on patients' demographic information, patients' self-reported signs and symptoms, symptoms of anxiety/depression, and disease burden-related measures (WTP, TTO, and DLQI), whereas the face-to-face interview included questions on clinical information. The severity of rosacea symptoms was assessed by patients themselves and clinicians using a Visual Analog Scale (VAS) (23)–a horizontal 10 cm VAS with the starting point labeled “none” and the endpoint labeled “very severe” (range of values, 0–10).
We evaluated anxiety and depression separately using a seven-item Generalized Anxiety Disorder scale (GAD-7) and a nine-item Patient Health Questionnaire (PHQ-9) (24, 25). The reliability and validity of the Chinese versions of these scales have been confirmed previously (26). Based on the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) criteria, the GAD-7 scale focuses on the presence of 7 core anxiety symptoms in the last 2 weeks, and can be categorized into four severity groups: none (0–4), mild (5–9), moderate (10–14), and severe (15–21). Similarly, the total score of PHQ-9 ranges from 0 to 27, and can be categorized into 4 categories: none (0~4), mild (5~9), moderate (10~14), severe (15~19), and very severe (≥19). In the present study, patients who scored 5–9 and ≥10 on the GAD-7 were deemed to have mild and moderate-to-severe anxiety, respectively. Patients who scored 5–9 on the PHQ-9 were classified as having mild depression, whereas those who scored≥10 were considered to have moderate-to-severe depression.
Assessment of Disease Burden
Quality of life: We utilized the DLQI to assess the effect of rosacea on the quality of life of the patients. The DLQI scores range from 0 to 30, with grade 1 (0~1) indicating no e?ect on the patient's quality of life, grade 2 (2~5) indicating a mild effect, grade 3 (6~10) indicating a moderate effect, grade 4 (11~20) indicating a severe effect, and grade 5 (21~30) indicating very severe impact on the patient's life.
Economic burden: We used WTP, which has been widely used in previous studies, to measure the economic burden of rosacea on the patients (18, 21, 27). Patients were asked what percentage and absolute sum of their monthly income they are willing to pay for the disease to be cured.
Psychological burden: To further assess the psychological burden of rosacea on the patients, we used TTO as previously described (27). We asked the patients the amount of time they were willing to “trade off” in exchange for a health status without rosacea.
As described previously (27), a definition of “high burden (HB)” includes of the three domains mentioned above, together with the number of adaptive behaviors. Each domain is recognized as positive if its individual value exceeds the median score of all the patients.
Statistical Analysis
Categorical variables were described as absolute and relative frequencies, whereas continuous variables were expressed as means, standard deviations, and medians. The chi-square test was used to compare the prevalence of anxiety and depression among patients with different sociodemographic and clinical characteristics. The chi-square test and Spearman's correlation analysis were used to assess the relationship between anxiety and depression and disease burden. Variables that were identified as significant using univariate analysis were further investigated using multivariate analysis. Multivariate analysis was performed by using multiple logistic regression (forward elimination: Wald) to identify variables that were independently associated with anxiety and depression among rosacea patients. Relative risk estimates were calculated as odds ratios (ORs) with 95% confidence intervals (CIs). A two-tailed 5% significance level was used in this study. All analyses were performed using SPSS for Windows (version 20.0; SPSS, Chicago, IL, USA).
Results
Prevalence of Anxiety and Depression Among Rosacea Patients
A total of 774 patients were enrolled in this study; 417 (53.9%, 95% CI: 50.4–57.4%) suffered from anxiety, whereas 450 (58.1%, 95% CI: 54.7–61.6%) had depression. Among the patients who had anxiety, 20.0% (95% CI: 17.2–22.9%) reported moderate to severe symptoms. For the patients who had depression, 25.8% (95% CI: 22.8–28.9%) reported moderate to severe symptoms.
Characteristics of Anxiety and Depression Among Rosacea Patients
Demographic and Clinical Data
The demographic and clinical information of the participants are summarized in Table 1. Out of the 774 patients enrolled in this study, 75 were males and 699 were females. The mean age of the participants was 33.01 ± 11.13 years and their age range was 18–70 years. Regarding disease duration, 77.6% (n = 601) of the patients have had rosacea for less than a year. Furthermore, 29.1% of the patients (n = 225) had more than six adaptive behaviors (consciously avoiding heat, sun exposure, and exercise and so on).

Factors associated with anxiety were younger age, female gender, and higher requirement for appearances in the workplace. Factors linked to depression were younger age and an unmarried status. Moreover, we found that patients who had more rosacea signs displayed a significant association with anxiety, but no association with depression. It is widely accepted that patients have identified many factors that can easily induce or exacerbate rosacea, thus making them consciously avoid these triggers in daily life, named “adaptive behaviors.” Patients who had anxiety or depression tended to have more adaptive behaviors to avoid recurrence and exacerbation of rosacea.
Additionally, we found that the patients' self-reported signs and symptoms, rather than the clinically evaluated ones, were significantly associated with both anxiety and depression in a logistic regression model before and after adjusting for demographics. As shown in Table 2, the number of times flushing occurred in the past 24 h, severity of flushing, flushing-induced sleep disorders, and distress in daily life, burning, stinging, itching, and erythema have significantly positive associations with anxiety and depression. Furthermore, we found that the severity of anxiety or depression increased with increasing VAS scores of self-reported symptoms (Table 3).

Disease Burden
We initially used the DLQI to assess the burden of rosacea. Judging by the DLQI scores, rosacea had a moderate-to-severe impact on the quality of life of 73.9% (n = 572) of the patients (DLQI score≥6). The mean ± SD total DLQI score of patients who had anxiety and depression was 14.034 ± 7.511 and 13.336 ± 7.497, respectively, and 8.048 ± 6.348 and 8.407 ± 6.791 for the patients who did not have anxiety and those who did not have depression, respectively. We used WTP and TTO to further evaluate the economic and psychological burden of rosacea on the patients, respectively. Overall, we revealed that the relationship of anxiety/depression with disease burden correlated in a significant way (Table 4).

DLQI, Dermatology Life Quality Index.
The Prevalence of Anxiety and Depression Among “High-Burden” Patients
Based on the insights from previous studies, some patients who have rosacea can be defined as a “high-burden (HB)” population who are characterized by an adverse quality of life, adaptive behaviors, and other economic and psychosocial factors (27). Accordingly, applying this definition to our data, we found that HB patients accounted for 17.8% (n = 138) of the patients enrolled in this study.
As mentioned previously, we have determined that patients with anxiety or depression had a significantly positive result in three domains that are indicative of HB (DLQI, WTP, and TTO). Further, we also found that there is a positive correlation between the final domain of adaptive behaviors and anxiety (r = 0.163, P = 0.000) or depression (r = 0.169, P = 0.000).
Risk Factors for Anxiety and Depression
Multivariate analysis further identified several predictors for anxiety and depression (Table 5). The risk of anxiety was significantly increased in younger patients, those who experienced more severe stinging, those who had higher DLQI scores, and those who had more adaptive behaviors. Except stinging, the factors mentioned above and more severe flushing-induced life distress predict a higher risk for more severe anxiety. Regarding depression, four factors were significantly associated with an increased risk of depression; they include: younger age; more severe flushing-induced sleep disorders, higher DLQI score, and having more adaptive behaviors. In addition to these factors mentioned, patients who experienced more severe stinging also indicated a higher possibility to suffer from more severe depression.

Discussion
In this study, we investigated the prevalence of anxiety and depression in Chinese rosacea patients. In addition, we identified several possible predictive factors for anxiety and depression among rosacea. These results can help clinicians to identify the psychological distress of patients early, thereby facilitating prompt intervention and comprehensive rehabilitation.
Our results showed that 53.9 and 58.1% of the patients had anxiety and depression, respectively, a finding which is comparable to that of a survey conducted by the National Rosacea Society (28). However, the prevalence of anxiety in the present study was much higher than that of a study conducted in Turkey (29). Further, the prevalence of anxiety and depression in the present study was higher than that reported in another Chinese study (30). These discrepancies in the prevalence of anxiety and depression between our data and others' may be attributed to differences in location, types of screening instruments, or the sampling methods used. On the other hand, given that a negative association exists between age and anxiety/depression in our study, the relatively younger age of the patients in the present study may explain the higher prevalence of anxiety and depression recorded in the study.
The causes of the high prevalence of anxiety and depression among rosacea patients are still unclear. However, several plausible reasons may be responsible for the association between anxiety/depression and rosacea. Firstly, rosacea patients tend to experience embarrassment, anxiety, low self-esteem, and decreased quality of life (9, 10, 21) because of their facial face. Secondly, subjective symptoms are always bothersome and may be a source of psychological distress (22). Thirdly, rosacea is extremely susceptible to external stimuli and its severity can fluctuate in accordance with emotional stress; this can lead to recurrence of signs and symptoms, thus further aggravating the patient's psychological sequelae. Finally, psychological distress being involved in the pathogenesis of rosacea (20) may cause an aggravation of inflammation and neurovascular response by increasing the release of cytokines, chemokines, and neurotransmitters from cutaneous cells (31–33).
Our results highlighted many factors that have significant associations with anxiety and depression. From the perspective of demographics, we found that younger patients were more prone to anxiety and depression than older patients. Consistent with the findings of some previous studies (29, 34), we also found that female rosacea patients were more susceptible to anxiety than male patients. However, some other previous studies had contrasting results (9, 22, 35). In the present study, the gender-related differences may be explained by the fact that females are generally more sensitive to changes in their physical appearance than males. Accordingly, we found that patients whose occupations have higher requirements for physical appearance were prone to anxiety. This finding further emphasizes the crucial influence of physical appearance on quality of life, from impairment of social adaptations to psychological sequelae.
Our findings support previous studies that have identified a link between the severity of subjective symptoms and the presence or severity of anxiety/depression in rosacea patients (12). Additionally, we found that the severity of self-reported and clinically evaluated erythema were not parallel. Further, we found that anxiety and depression were more prevalent among patients who had more severe self-reported symptoms but had no significant association with the severity of the symptoms observed by a clinician. However, in daily practice, clinicians often focus exclusively on the visible signs and overlook the invisible symptoms; this makes the patient feel that his/her subjective symptoms are easily neglected.
In addition, we also investigated the possible association between anxiety/depression and the disease burden of rosacea. Consistent with results of prior studies, we found that DLQI score has a significantly positive association with anxiety and depression (22, 30). We also identified a correlation between the self-perceptions of flushing-related sleep disorders/life distress and the presence or severity of anxiety/depression in rosacea patients. These findings highlight that the mental and functional impairments associated with the disease largely contribute to anxiety or depression. In addition to DLQI, we utilized WTP to assess the economic burden of rosacea (18, 21, 26, 36), and TTO to evaluate the psychosocial burden of rosacea (27). We observed that patients who had anxiety and depression preferred to invest more money and trade more of their lifetime for a complete cure of rosacea. In addition to these classic indicators of disease burden, “adaptive behavior” was another challenging issue for the patients. It is widely accepted that patients have identified many factors that can easily induce or exacerbate rosacea, thus making them consciously avoid these triggers in daily life (7, 29); these avoidance habits are termed “adaptive behaviors.” Based on the results, we found that patients who had more adaptive behaviors were more likely to be anxious or depressed, indicating that the more lifestyle habits they had to change, the larger the impact of the disease on their lives, and the higher the psychological burden.
A new concept of HB in rosacea patients was recently proposed. This concept indicates that for HB rosacea patients, at least three of four domains are positive (DLQI, WTP, TTO, and lifestyle) (27, 29). Based on this definition, we identified 17.8% HB rosacea patients in the present study, a finding which is similar to that of a previous study (27). Further, we found that anxiety and depression were more prevalent and severe in HB rosacea patients. Taken together, these results indicate a close relationship between anxiety and depression and the high disease burden of rosacea. The recognition of HB patients may encourage clinicians to screen for anxiety and depression in rosacea patients.
Considering the high incidence of anxiety and depression among rosacea patients, especially in HB patients, it is necessary to identify patients who have anxiety or depression to avoid serious consequences such as suicide. Our results highlighted that younger age, more severe self-reported symptoms, higher DLQI score, and having more adaptive behaviors are predictive factors for the presence and severity of anxiety and depression.
Since utilizing GAD-7 and PHQ-9 scales that have numerous questions is not practical in a clinical setting due to the restricted duration of clinical visits, asking questions using the VAS would be of simple and value. Therefore, to screen for anxiety and depression, we recommend the use of the following questions in clinical practice:
Score the effect of rosacea on your sleep using the VAS.
Score the effect of rosacea on your daily life using the VAS.
Describe the severity of your symptoms (including flushing, stinging, burning, and itching) using the VAS
How many lifestyle changes have you made due to rosacea?
These questions will help physicians to recognize patients who have psychological burdens and o?er them psychological counseling earlier.
This study has some limitations. Firstly, as this was a single-center survey, the sample population is not representative of the whole population of China. Secondly, the choice of scale for the assessment of anxiety and depression may have the potential to skew the detection of the presence and severity of anxiety and depression in rosacea patients. Lastly, we overlooked the prevalence of anxiety and depression in rosacea patients after proper treatments, and thus not being able to provide comprehensive data to fully demonstrate that rosacea can cause anxiety and depression. However, these limitations are unlikely to confound the comparison of the groups evaluated in this study. We will continue to explore these issues more thoroughly and comprehensively in further studies.
In conclusion, the proportion of rosacea patients who have anxiety or depression is large. However, the psychological distress experienced by these patients is usually neglected by clinicians. Our study revealed that younger age, more severe self-reported symptoms, and higher disease burden may indicate the possibility of anxiety or depression, especially when clinical signs and self-reported symptoms are inconsistent or if patients have apparently impaired quality of life. Psychological intervention should be taken into consideration when prescribing atreatment regimen.
