“…Our study showed that 35.8% of students got an acne treatment without a prescription; which are most probably over the counter drugs. This is comparable to the general estimation that 30% of affected acne patients are likely to use OTC treatments [14]. Surprisingly the treatment duration expectation was less than one week in 9.9% of students and more than 2 months in 39.1% of students only.…”

Acne is a common skin disorder of teenagers and continues into adulthood. Research has been limited regarding acne prevalence, perception and health care utilization in Saudi Arabia. The objective of this study was to assess acne prevalence in final year female medical students in Jeddah, Saudi Arabia using the global acne grading system (GAGS) compared with student's self-report of their acne. This is a cross-sectional study conducted among 151 students during 2016, in which students were interviewed subjectively and examined objectively by a trained physician. This study showed that acne was reported subjectively by 83.4% of female students compared to 98% of students assessed objectively by the global acne grading system. 14.6% of students claimed having no acne while it was objectively present, which was statistically significant (Χ 2 = 15.4, P < 0.001). 41% visited a dermatologist and 28.5% waited 1 year until seeking a dermatologist. However, 35.8% of students got an overthe-counter drug for their acne. Surprisingly, treatment duration expectation was <1 week in 9.9% compared to >2 months in 39.1% of students. Acne was present in 41.1% of the students parents compared to 83.4% in their siblings. A total of 41.7% of student had trunk acne. 60.9% of students had scarring and 72.8% of them had pigmentation. Moderate to severe acne students had higher siblings acne history of 95.2% (Χ 2 = 5.85, P < 0.05), higher scaring of 73.8% (Χ 2 = 4.05, P < 0.05), and higher pigmentation of 85.7% (Χ 2 = 4.87, P < 0.05) which was statistically significant. Our study confirms that acne is very common in female medical students in Jeddah, Saudi Arabia with a prevalence rate of 98%. Knowledge regarding acne treatment was inadequate demonstrating the need for educational and awareness programs about early treatment that will prevent suffering from acne scarring or pigmentation.

“…Por outro lado, a entrevistadora não percebeu dificuldade na realização dos inquéritos. 8,10,11,23 Houve diferença significativa na idade de início da acne entre os grupos. Mesmo assim, 80% das mulheres do grupo adulto relataram o início das lesões ainda na adolescência, ratificando observações prévias de que a maioria dos casos de acne de mulheres adultas pode corresponder a persistência do quadro juvenil.…”

Resumo: FUNDAMENTOS: Acne é dermatose comum que acomete ambos os gêneros e todas as faixas etárias. Mulheres apresentam diferentes padrões clínicos da doença, além de frequente persistência da acne após a adolescência. OBJETIVO: Analisar características clínicas e epidemiológicas associadas às diferentes faixas etárias acometidas por acne feminina. MÉTODOS: Estudo transversal envolvendo mulheres com diagnóstico de acne, atendidas em ambulatório de dermatologia geral. Variáveis relacionadas à doença e às pacientes foram avaliadas com o emprego de questionário padronizado. RESULTADOS: Avaliaram-se 103 pacientes, cuja idade média na época da consulta foi 21,7 ± 7,3 anos. Definiram-se dois subgrupos com idade de corte de 21 anos e idades médias de 15,8 ± 2,3 e 28,0 ± 5,1 anos. Houve correlação entre a duração do quadro e a idade das pacientes na consulta (R = 0,7). Observaram-se diferenças entre os grupos nas frequências de uso de contraceptivo oral combinado (OR = 48,1), lesões no colo (OR = 11,6), lesões no dorso (OR = 0,2), predominância na topografia superior da face (OR = 0,1) e idade de início das lesões (OR = 1,8). No grupo de mulheres adultas, 80% relataram iní-cio do quadro antes dos 20 anos. CONCLUSÕES: Identificaram-se padrões clínicos cronológicos e topográficos que caracterizaram a acne feminina em diferentes faixas etárias, alertando para a importância da abordagem diagnóstica e terapêutica individualizada. Palavras-chave: Acne vulgar; Dermatologia; Estudos transversais; Hiperandrogenismo Abstract: BACKGROUND: Acne is a frequent skin disease that occurs in both sexes and all age-groups. Women present several clinical disease patterns; moreover, persistence after adolescence is common. OBJECTIVE: To analyze clinical and epidemiological characteristics associated with different age-groups affected by acne in women. METHODS: Cross-sectional study involving female patients diagnosed with acne, at a general dermatology outpatient clinic. Variables related to disease and patients were assessed through a standardized questionnaire. RESULTS: One hundred and three women were assessed. The average age of patients at the time of the consultation was 21.7 ± 7.3 years. Two groups were defined (cut-off age of 21 years), with means of 15.8 ± 2.3 and 28.0 ± 5.1 years. There was correlation between disease duration and current age (R=0.7). There were group differences among frequencies of covariables: combined oral contraceptive (OR=48.1), lesions located on upper chest (OR=11.6), lesions on upper dorsum (OR=0.2), predominance on upper half of face (OR=0.1) and age at disease onset (OR=1.8). Among adult women, 80% reported acne onset before 20 years of age. CONCLUSION: Chronologic and topographic patterns of female acne in different age-groups were defined, reinforcing the importance of an individualized diagnostic and therapeutic approach.

“…A recent study measuring the validity of self-report for acne showed that college students cannot accurately report that they have acne. 35 Again, although statistically significant, the prevalence ratios demonstrating an association between milk and acne were very low (maximum of 1.24). Thus, the clinical relevance of these results remains in question.…”

“…Studies that have compared self-report of acne with objective acne assessments have shown that people with acne are not able to accurately report that they have acne. 35 Validity of self-report is moderate at best. Furthermore, recall bias may be playing a role in this study.…”
