Study results published in the Journal of the American Academy of Dermatology suggest a family history of acne and various lifestyle factors are associated with adult acne in women.
Researchers measured factors associated with adult female acne in 248 women aged 25 years or older and 270 female controls who were a mean age of 36.4 years old. The control group was diagnosed with undisclosed conditions other than acne. Among the patients with acne, 50.2% had moderate acne, 42% had mild acne and 7.8% had severe acne.
Multivariate analysis indicated a significant association between adult female acne and a history of acne in parents or siblings. Other factors associated with adult female acne included history of acne during adolescence, being an office worker compared with being unemployed or a housewife, having no previous pregnancies, having hirsutism, having a high or very high level of reported psychological stress during the previous month and a low intake of fruits of vegetables.
“We did not establish an onset date for acne, and our associations may not reflect a causative role but may, at least in part, reflect shared risk factors or consequences of established acne,” the researcher wrote. “Lifestyle factors may play an important role for acne development in adulthood, but their role should be further assessed in prospective studies.”
