Higher acne incidence among preadolescent girls linked to high BMI suggests a new study published in Pediatric Dermatology.
Researchers have found in a large population-based retrospective study that among preadolescent kids incidence of acne was associated with higher body mass index (BMI) percentiles. However incidence of acne was higher in girls than in boys.
Little is known about acne incidence in preadolescents and its potential association with body mass index (BMI). Our study aims to determine acne incidence in preadolescents and its association with BMI.
A population-based retrospective cohort study identified 7- to ≤12 year-olds with an initial acne diagnosis during 2010–2018, and incidence was calculated. Two age- and sex-matched controls without acne were randomly selected per case, and BMI was recorded.
Results
• A total of 643 acne patients were identified.
• Annual age- and sex-adjusted incidence rate was 58.0 per 10,000 person-years, higher in females vs. males, and increased with age
• Systemic medication use was associated with increasing BMI
• Median BMI percentile was higher among acne cases vs. controls, as was the proportion with BMI ≥95th percentile
Acne incidence is higher in preadolescent girls than boys and increases with age. Preadolescents with acne are more likely to be obese than those without acne. Those with higher BMIs are more likely to be given systemic treatment.
