acne scars tied with three risk factors: male gender, positive family history of acne, and acne severity
Three major risk factors for individuals with acne scars are having a positive family history of acne, being of the male gender, and severity of acne, according to recent findings published in the Skin Research and Technology.
Acne scar is a persistent complication of acne vulgaris. However, the prevalence and risk factors are still unclear. This study aimed to assess the global prevalence and risk factors of acne scars in patients with acne. A systematic search of published studies in three databases was performed and the meta-analyses were conducted.
Results
Finally, they included 37 studies involving 24 649 acne patients. And, the pooled prevalence of acne scars in these patients was 47% (95% confidence interval [CI]: 38–56%). Besides, the differences in prevalence were observed based on the subgroup analysis for age, gender, acne severity, source of patients, and so on. Subsequently, we quantified the relationship of three risk factors with acne scars: male gender (odds ratio [OR]: 1.58, 95% CI: 1.19–2.09), positive family history of acne (OR: 2.73, 95% CI: 1.26–5.91), and acne severity (OR for moderate acne: 2.34, 95% CI: 1.54–3.57; OR for severe acne: 5.51, 95% CI: 2.45–12.41).
