BACKGROUND AND OBJECTIVES: Recent data suggest that cow's milk allergy (CMA) has become more persistent, prolonging treatment via strict elimination of cow's milk products into a period of skeletal growth. The objectives of this study were to compare bone mineral density (BMD), vitamin D status, and dietary intakes of calcium and vitamin D between prepubertal children with persistent CMA and those with non-cow's milk food allergies (NCMA) as control subjects and to assess the use of and compliance to calcium and vitamin D supplementation among children with persistent CMA.

SummaryThere is little evidence regarding the associations between bone growth and environmental factors among growing children, especially in Asians. The aim of this crosssectional study was to search for the promotion factors of bone growth in Japanese children during growth. The study subjects were male (nϭ333) and pre/post-menarcheal female (nϭ179/nϭ68) school children aged 8-14 y. Bone status at the calcaneus was evaluated by quantitative ultrasound (Benus III), and the bone area ratio (BAR) was used as an evaluation index. Dietary intakes were assessed via brief self-administered diet history questionnaires. The participants were asked to record all of their activities for 3 d (2 weekdays and 1 holiday). They were also required to provide the most recent anthropometric measurement records at their schools and answer questions about the frequency of fractures and, for females, the length of time since menarche. Multiple regression analysis with dummy variables demonstrated that age, magnesium (more than the RDA), vitamin B1 (more than the RDA), mean physical activity intensity per day (more than 1.7 METs), vitamin C (more than the RDA) and calcium (more than the RDA) were signifi cantly positive infl uential factors of BAR for males. For premenarcheal females, age, vitamin A (more than the RDA), BMI, and mean physical activity intensity per day (more than 1.7 METs) were signifi cantly positive infl uential factors of BAR, and for postmenarcheal females, only BMI and age were signifi cantly positive infl uential factors of BAR. The results suggest that several manageable factors correlate with the bone mass, and the associations differ depending on gender and menarcheal status.

“…Calcium intake has been shown to correlate with bone density in healthy children (23), and maintaining adequate calcium intake during childhood and adolescence is necessary to attain a normal peak bone mass, which may be important in reducing the risk of fractures and osteoporosis later in life (24).…”

Introduction: Although hypoparathyroidism with hypocalcaemia is one of the most frequent clinical features of monoallelic microdeletion of chromosome 22q11 (22q11DS), bone mass and metabolism have not yet been assessed in these patients. Design: This study aimed to evaluate bone mass and metabolism in a cohort of patients, both children and adults, with 22q11DS. Methods: In twenty-eight patients with 22q11DS (median age 12.5, range 6.1-42.8 years), serum levels of ionised and total calcium, phosphate, parathyroid hormone (PTH), 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D, osteocalcin and bone-specific alkaline phosphatase (BSAP), and urinary deoxypyridinoline concentrations were evaluated. In these patients, bone mineral density (BMD) was evaluated by dual-energy X-ray absorptiometry (DXA) examination, and volumetric BMD (bone mineral apparent density (BMAD)) was calculated. The data obtained from paediatric and adult patients were compared with two age-, sex-and body sizematched healthy subject control groups. Results: Patients with 22q11DS showed a reduced BMAD Z-score compared with controls (P!0.001). These patients also had significantly lower ionised (P!0.001) and total calcium (P!0.05) levels as well as lower PTH levels (P!0.05), compared with the controls. In particular, children and young patients with 22q11DS had significantly lower serum osteocalcin levels (P!0.001), BSAP levels (P!0.001) and urinary deoxypyridinoline concentrations (P!0.001) than controls. These results were not confirmed in adults. Finally, patients with hypoparathyroidism and/or hypocalcaemia at the time of the study showed significantly lower ionised (P!0.001) and total calcium levels (P!0.001), PTH levels (P!0.05), BSAP levels (P!0.001), osteocalcin levels (P!0.001) and urinary deoxypyridinoline concentrations (P!0.001), compared with patients without hypoparathyroidism and/or hypocalcaemia. Nonetheless, the BMAD Z-score did not show substantial differences between these two groups. Conclusions: Subjects with 22q11DS have a significant reduction in bone mass that appears to be more severe in adults who have already attained peak bone mass than in children who are still growing. Therefore, we suggest a close monitoring of bone mass and metabolism in 22q11DS patients.
