Acne vulgaris is a dermatological disorder that is related to inflammation and oxidative stress. Recent studies have also suggested diet as a potential reason for acne. Considering the inconsistency of the few previous reports, the present study aimed to determine the levels of vitamin D, adiponectin, oxidative stress, lipid profile and nutrient intakes in females with acne.
Forty females with acne vulgaris and 40 age-matched healthy females were included in this study in Shiraz, Iran. Data on their sociodemographic status, acne history, and anthropometric indices were collected. Blood samples were taken to determine the levels of 25-hydroxyvitamin D, adiponectin, malondialdehyde, total antioxidant capacity, and lipid profile. Three 24-hour dietary recalls were also obtained from each of the individuals to evaluate nutrient intakes. Data were analyzed using the Chi-square test, Independent-samples t-test or Mann–Whitney U-test, and Logistic Regression.
Patients with acne had a significantly higher family history of acne compared to controls (P=0.006). Serum level of malondialdehyde was significantly higher in cases (P=0.01), while high-density lipoprotein cholesterol was significantly lower (P=0.02). Moreover, significantly lower fiber intake was observed in cases compared with controls (P=0.007). In the multivariate analysis, a family history of acne and increased malondialdehyde levels were risk factors for acne, whereas a higher fiber intake was protective.
Family history of acne, oxidative stress, dyslipidemia, and lower dietary fiber intakes may play a role in acne pathogenesis. An early assessment of these parameters may be useful for planning treatment procedures.
