Abstract

BACKGROUND:

Acne is one of the most common chronic inflammatory dermatological diseases among adolescents.

OBJECTIVES:

We sought to estimate the prevalence of acne among schoolchildren and its association with puberty, body mass index (BMI), acne history of parents, nutritional habits, smoking and alcohol consumption.

METHODS:

A cross-sectional study was conducted on 1277 pupils aged 7-19 years. Children were interviewed with self-administered questionnaires, and were subsequently examined by one specially trained dermatologist. To evaluate the onset of puberty, girls provided details about their menarche and boys--about their facial hair growth.

RESULTS:

The overall response rate of the study was 51.4%. The prevalence of acne among respondents was 82.9%, and was strongly age-dependent with highest rates in the age groups of 13-15 and 16-19 years. The prevalence of pre-pubertal acne among participating girls and boys was 69.9% and 73.6% respectively. The main risk factors of acne were facial hair growth in boys (OR = 4.9), menarche in girls (OR = 3.1), overweight/obesity (BMI ≥ 25 kg/m(2) at 18 years of age) (OR = 2.6), acne history from both parents (OR = 2.6) and from mother alone (OR = 2.1). We did not find any associations between acne and nutritional habits, smoking or alcohol consumption. The self-reported prevalence of acne among children who refused to take part in the study was lower than that among participants of the study.

CONCLUSIONS:

The overall prevalence of acne among schoolchildren is high and age-dependent. The onset of puberty, overweight/obesity and history of acne from both parents are the top risk factors for acne.
