Heng AHS, Say YH, Sio YY, et al. - Researchers conducted this cross-sectional study for examining the prevalence of acne, acne severity, and scarring grades, and their associated epidemiological risk factors among a cohort of the Singapore Chinese population. In total, 3,888 individuals (2,090 cases/1,798 controls; median age = 21 ± 4.589; range 17–71) completed an investigator-administered questionnaire as part of a cross-sectional study, which involved sociodemographics, familial medical history, lifestyle factors, dietary habits, and acne history. A key predisposing factor in determining acne presentation, severity, and scarring is a positive family history. Demographic factors (gender, age) and sedentary lifestyle (increased computer/TV usage) affect acne presentation, whereas dietary habits (milk and butter consumption) affect acne severity and scarring. The predisposing factors identified in this study may aid in the understanding of acne pathophysiology and, as a result, the development of interventions that specifically target modifiable risk factors.
