Energy and Dietary Intakes in Adult Atopic Dermatitis

ABSTRACT

@#Introduction: Studies on nutrition among adult AD, a chronic inflammatory skin condition, are lacking. The objective of this cross-sectional study was to investigate the energy, micro and macro nutrient intakes. Methods: Sixty two adult participants defined by the Hanifin-Rajka criteria were included. AD severity was determined using SCORAD index and objective SCORAD. Demographic data and a three-day 24-hour dietary recall were collected and analyzed. Basal metabolic rate (BMR) was estimated using Schofield’s equation. The Energy Intake (EI): BMR ratio was used to identify under reporters (EI:BMR<1.2). To understand food preferences, main food groups consumed, meat (chicken, beef, and pork), seafood (fish, crustaceans, and mollusk), vegetables, fruits, including eggs and milk were examined. To ascertain food avoidance, open ended questions were asked. Results: Significant differences between the severity of AD groups and energy intake, vitamin A, beta carotene, magnesium, and energy intake-basal metabolic rate ratio (EI: BMR) were seen for SCORAD index. Energy intake was significantly lower among severe AD. Vitamin A and magnesium intake was lower among severe AD. Saturated fat intake was higher among mild AD. EI: BMR was inversely correlated with objective SCORAD. Seventy seven percent of participants were under reporters. Almost 10 percent reported avoiding some form of seafood; predominantly form the crustacean or mollusk group. Conclusion: Subjective symptoms, a component of SCORAD index but not objective SCORAD, may have contributed to significant differences seen. Lower energy intake in severe AD was due to reduced dietary intake during flares rather than underreporting.
