Evaluating the Dietary Intakes of Energy, Macronutrients, Sugar, Fiber, and Micronutrients in Children With Celiac Disease.

OBJECTIVES: Children with celiac disease (CD) follow a lifelong gluten-free diet. This restrictive diet may be associated with nutritional compromise. Our objectives were, therefore, to evaluate the dietary composition (energy, macronutrients and micronutrients, and fiber) in children with CD compared with healthy controls (HC) and relationship between dietary composition and socioeconomic status. METHODS: This cross-sectional, case-control study recruited children with CD ages 2 to 18 years and HC matched for age, sex, and socioeconomic status. Clinical, sociodemographic, and dietary information were collected. A false discovery rate correction was applied to the P-value for multiple comparisons (q-value). RESULTS: Sixty-five CD children were matched with 65 HC (mean [SD] age: 10.2 [3.6] vs 10.1 [3.7] years, P = 0.96). Compared with HC, CD children had higher intakes of energy (2413.2 [489.9] vs 2190.8 (593.5) kcal/day, P = 0.02), total fat (818.1 ±â€Š180.9 vs 714.3 ±â€Š212.2 kcal/day, q = 0.018), and subtypes of fat (saturated, polyunsaturated, and monounsaturated). There were no differences in other macronutrients, sugar, micronutrients, or fiber between CD and HC, and no difference in dietary intake among CD between socioeconomic disadvantage versus advantage. Children with CD had lower weight z-scores (-0.06 [1.05] vs 0.47 [0.96], P = 0.003) and body mass index (BMI) z-scores (-0.02 [0.88] vs 0.41 [1.09], P = 0.02) than HC. CONCLUSIONS: Children with CD had higher calorie and fat intake compared with HC. Despite this, CD children had lower weight and BMI z-scores compared with HC.
