Correlation between Family History and the Age of Onset of Childhood Acne in Relation to Sex and Type of Acne

Acne vulgaris is a common chronic skin disorder of the pilosebaceous unit with a wide range of clinical presentations, which depend on the age of onset of acne, sex, family history of acne, and genetic factors, especially the genes affecting keratinization and desquamation. This retrospective study investigated pediatric acne using the patients' past medical history, with patients aged from newborns to 15 years of age. Acne were further stratified by 5 parameters: sex, age, family history, acne type, and localization. Our main aim was to investigate the possible association between selected parameters and the presence or absence of family history of acne. We did not find statistically significant correlation between sex, age of onset, and positive family history of acne. Furthermore, we did not find any association between age of onset and family history according to family members (mother/father/brother or sister). However, we found statistically significant correlation between sex and type of acne. This retrospective analysis of pediatric acne in Croatia did not reveal statistically significant correlation between positive family history and sex, age of onset, and clinical type of acne. In analyzing the correlation between family history and localization of acne, however, we found that the number of patients with acne localized on both the face and trunk and positive family history was statistically significant higher than expected.
