Abbreviation: aOR, adjusted odds ratio.
a
Values based on intakes of 100 g/d.
b
Analysis included 11 068 never acne participants (54%), 7983 past acne participants (39%), and 1361 current acne participants (7%). Data are missing for some variables used in adjustment; therefore, the sample number (20 412) differed from the overall population.
c
P values were determined in a multivariate logistic regression after adjustment for total calorie intake, the number of dietary records completed, sex, age, smoking status, physical activity, educational level, body mass index, and history of cancer, diabetes, cardiovascular disease, or depressive symptoms.
