“…Regarding scar assessments, comparing self-to local professional assessments, the pilot suggests the need for dermatological assessments rather than reliance on self-assessment. As opposed to an earlier study, the pilot results hint towards a tendency of participants to minimise the presence of acne scars rather than overestimate, which was earlier found 19 . It was shown that a simple majority consensus is sufficient to determine the presence or absence of acne scars, so the use of three dermatologists is recommended for final evaluation (minimum number needed to reach a simple majority consensus).…”

Pilot study for the evaluation and adaptation of a Four Item-Acne-Scar Risk Assessment Tool (4-ASRAT): a resource to estimate the risk of acne-induced scars

Background: Acne-induced scarring is associated with a similar burden as acne, i.e. diminished quality of life, and may be avoided if patients receive appropriate and timely acne treatment. In 2017, a four item-Acne-Scar Risk Assessment Tool (4-ASRAT) was designed by Tan et al. to categorise patients with acne into lower-risk or higher-risk for acne scarring. Its applicability outside the initial study population (France, Brazil and United States) remains to be determined. Methods: A study protocol was developed to create a systematic approach for validating and adapting 4-ASRAT to different populations, Ecuador in this case. The protocol was reviewed by 11 local and international dermatologists and pilot-tested in an Ecuadorian population using a sample of 10 participants who currently had or had had acne. Feedback from the pilot study was used to improve the study protocol. The results of the pilot study are included here, and the final study protocol is available as extended data. Results: The protocol proved to be applicable. Images taken of participants were a valuable resource for dermatological evaluation about the presence or absence of acne scars. Tangential light is necessary for this evaluation. Although dermatological assessments varied, we concluded that assessment by three local dermatologists for each participant was adequate for reaching a consensus on the presence or absence of acne scars. Conclusions: Considering the morbidity related to acne and acne scars, tools designed as prevention that alert patients about risk of developing scarring are necessary. The proposed protocol shows a feasible way of validating and adapting 4-ASRAT to different populations.

“… 10 This may stem from a true unawareness, denial, or a reluctance to be branded as having the same disease as persons with more severe forms of acne. In a Brazilian study among male adolescents with acne, Almeida et al 19 reported that the prevalence of active acne obtained by dermatological examination was higher than that for self-reported acne, concluding that self-reporting of acne in adolescents is an inadequate instrument for epidemiological studies.…”

BackgroundAcne vulgaris is a common skin condition, which affects most adolescents at some point in their lives. It has been found to have a significant impact on their psychological well-being and has been associated with depression and suicide ideation. Many studies have assessed the impact of acne vulgaris on the quality of life (QoL) in different population subgroups around the world, but there is a dearth of reports from the African subcontinent. This study thus seeks to assess the severity of acne vulgaris and determine its effect on the QoL of adolescents in Lagos, Nigeria.MethodsIn a cross-sectional survey employing a two-stage sampling method, the severity of acne vulgaris and its impact on the QoL of adolescents attending a senior secondary school in Lagos, Nigeria was assessed using the Global Acne Grading Scale (GAGS) and the Cardiff Acne Disability Index (CADI), respectively. The correlation between the results of the GAGS and CADI was also determined.ResultsOne hundred and sixty adolescent students with acne were recruited, with males accounting for 51.9% and females 48.1%. The mean and standard deviation of the GAGS severity scores were 11.3±5.4 for males and 11.9±5.4 for females. Only one student had severe acne vulgaris (GAGS, 31–38), 10% moderate (GAGS, 19–30), and 89.4% mild (GAGS, 1–18). The overall CADI score was 3.4±3.0, which suggests mild impairment in QoL; however, the solitary student with severe acne had severe QoL impairment. There was a weak positive correlation between the GAGS and the CADI score.ConclusionMost adolescents in our study had mild acne vulgaris, and the overall impact on their QoL was mild. However, the correlation between the psychosocial impact and acne severity was weak. There is a need for similar studies in other parts of the country and for further studies to determine the adequacy of the existing instruments in assessing the impact of acne vulgaris in Nigerian adolescents.

“…Self‐rated acne severity grading scales have been increasingly used in acne epidemiological surveys . Their advantage is that a patient‐based measure factors in the multiple dimensions of acne into a singular outcome response.…”

A global perspective on the epidemiology of acne

SummaryAcne is estimated to affect 9Á4% of the global population, making it the eighth most prevalent disease worldwide. Epidemiological studies have demonstrated that acne is most common in postpubescent teens, with boys most frequently affected, particularly with more severe forms of the disease. This paper aims to provide an update on the epidemiology of acne worldwide. Recent general and institutional studies from around the world have shown that the prevalence of acne is broadly consistent globally (with the exception of specific populations, which are discussed). However, this review highlights that there is a wide range of disparate outcome measures being applied in epidemiology studies, and we emphasize the need to develop a widely accepted, credible, standard assessment scale to address this in the future. In addition we discuss special populations, such as those devoid of acne, as well as the impact of potential determinants of acne on disease epidemiology.Acne vulgaris, or acne, is a common condition with a wide range of potential harms and associated costs. The former include symptomatic discomfort, scarring, emotional and psychosocial distress, occupational consequences and potential psychiatric disturbances including depression and suicide. Identification of individuals at risk of these sequelae can contribute to reducing the morbidity associated with acne.The Global Burden of Disease Project estimates the prevalence of acne at 9Á4%, ranking it as the eighth most prevalent disease worldwide. 1,2This initiative established prevalence and disability data from primary research manuscripts and databases, and conducted subsequent data analysis with a Bayesian meta-regression methodology, providing a means to harmonize discordant data and to account for a lack of data in geographical, temporal or other demographic items.2 While this project uses primary research findings to inform global metrics, there has not been a recent attempt to collate and present the world literature on acne prevalence collected over the past decade and a half. The last such review of acne prevalence in both general and schoolaged populations comprised literature up to 1995.

Sensitivity and specificity of self‐reported acne in 18‐year‐old adolescent males

Abstract: Our findings showed that sensitivity and specificity of self-reported acne was very low, pointing out that, in a sample of adolescents, self-reporting of acne shows itself as an inadequate instrument for epidemiological studies.
