What does this research mean for the field?

Frequent consumption of fast food, sweets, and non-fermented milk, along with poor sleep and high stress, are associated with increased acne severity, whereas fermented dairy products, fruits, vegetables, and exercise are associated with reduced severity. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Implication

Cross-sectional study observes lower acne severity with fermented dairy and higher risk with non-fermented milk in youth, suggesting distinct physiological impacts across dairy subtypes.

Key Points

To examine how dietary patterns, dairy subtypes, and other lifestyle factors correlate with the severity of acne vulgaris among youth.
Conducted a clinic-based cross-sectional study of 423 acne patients (mean age 20.2 years) at dermatology clinics in northern Jordan.
Graded acne severity using the validated Global Acne Severity Scale and collected lifestyle and dietary details via structured interviews.
Identified correlates of moderate-to-severe acne using multivariate logistic regression analysis, including post hoc dairy-subtype evaluations.
Significant risk correlates for moderate-to-severe acne included frequent fast-food intake (aOR = 1.56, 95% CI: 1.21–1.81), sweets (aOR = 1.51, 95% CI: 1.15–1.98), lack of sleep (aOR = 1.19, 95% CI: 1.02–1.36), and high psychological stress (aOR = 1.63, 95% CI: 1.28–1.93).
Protective inverse associations with acne severity were observed for regular fruit and vegetable consumption (aOR = 0.66, 95% CI: 0.41–0.84) and regular exercise (aOR = 0.76, 95% CI: 0.44–0.89).
Dairy-subtype analysis revealed inverse associations with moderate-to-severe acne for yogurt (aOR = 0.65, 95% CI: 0.53–0.83) and labneh (aOR = 0.63, 95% CI: 0.51–0.79), whereas non-fermented milk was positively associated with severity (aOR = 1.37, 95% CI: 1.12–1.68).
