Micronutrient Status and Nutritional Intake in 0- to 2-Year-old Children Consuming a Cows' Milk Exclusion Diet.

OBJECTIVES: To study micronutrient status and nutritional intake from complementary feeding in children on a cows' milk exclusion (CME) diet. METHODS: Fifty-seven children with cows' milk allergy, younger than 2 years, were included in a cross-sectional study. Blood was analyzed for micronutrient status. Complementary feeding was defined as all solids and liquids except of breast milk, and assessed by 3-day food diary. The results were analyzed according to 3 feeding patterns: mainly breast-fed (mBF), partially breast-fed, and no breast milk group (nBM). RESULTS: The children had a median age of 9 months and micronutrient status was within normal range for total homocysteine (p-tHcy), s-B12, s-folate, b-Hb, s-ferritin, s-zinc, and s-25(OH)D. There were no significant differences between feedings groups, except for B12-biomarkers. The mBF had higher p-tHcy (P < 0.000) and lower s-B12 (P = 0.002) compared nBM. Vitamin B12 deficiency (p-tHcy >6.5 µmol/L combined with s-B12 <250 pmol/L) was found in 12% of participants, most frequently among the mBF (36%) and none in nBM group (P = 0.009). Vitamin B12 intake from complementary feeding was negatively correlated with p-tHcy (r = -0.479, P = 0.001) and positively with s-B12 (r = 0.410, P = 0.003). Iron deficiency anemia was found in 5%. Iron intake correlated positively with b-Hb (r = 0.324, P = 0.02). Zinc deficiency was found in 7% and low 25(OH)D in 9%. Vitamin D intake was positively correlated with the use of supplements (r = 0.456, P = 0.001). CONCLUSION: The risk of B12 deficiency was high in mBF infants on CME diet, and complementary feeding was associated with better B12 status. Iron, zinc, and vitamin D deficiencies were present in all feeding groups. Complementary feeding should be introduced at 4 to 6 months of age. Vitamin D supplement is recommended to ensure adequate intake.

Minor impact of juvenile arthritis on nutritional status in young adult patients.

OBJECTIVE: Growth abnormalities and poor nutritional status have been reported in children with juvenile idiopathic arthritis (JIA). The aim of this study was to evaluate the impact of juvenile chronic rheumatic disease on current nutritional status in adult patients in remission or with active disease. METHODS: One hundred thirty-eight women and 82 men, aged >20 years, with JIA were studied after a mean disease duration of 15.5 +/- 2.3 years. Eighty-four (61%) of the women and 49 (60%) of the men were in remission. Forty-one healthy women and 54 healthy men served as a reference group. Body composition was analyzed by dual-energy x-ray absorptiometry. RESULTS: There was no difference in height or body mass index (BMI) between patients and healthy subjects. However, female patients with systemic disease had significantly reduced BMI compared with those with pauciarticular JIA (P < 0.001), and female patients who used or had been using corticosteroids had significantly lower weight, height, and BMI compared with the patients who had never used corticosteroids (P < 0.05). Female patients in remission had significantly more lean body mass compared with healthy controls (P < 0.05) and significantly less body fat was found in both women and men (P < 0.01 for both). Patients with active disease had the same amount of lean body mass as the healthy controls, but significantly less body fat (P < 0.05 for women and P < 0.01 for men). CONCLUSION: Adult patients with JIA had attained normal height, weight, and BMI, with the exception of women with systemic JIA and those who were using or had used corticosteroids. Patients with JIA in remission seemed to have a better nutritional status than healthy subjects.
