Bone mineral density accrual in students with autism spectrum disorders: Effects of calcium intake and physical training / Mahmood GOODARZI in Research in Autism Spectrum Disorders, 6-2 (April-June 2012)
[article]
Titre : Bone mineral density accrual in students with autism spectrum disorders: Effects of calcium intake and physical training Type de document : Texte imprimé et/ou numérique Auteurs : Mahmood GOODARZI, Auteur ; Rasool HEMAYATTALAB, Auteur Année de publication : 2012 Article en page(s) : p.690-695 Langues : Anglais (eng) Mots-clés : Weight-bearing exercise Calcium Bone mineral density (BMD) Autism Index. décimale : PER Périodiques Résumé : The purpose of this study was to investigate the effects of weight bearing exercise and calcium intake on bone mineral density (BMD) of students with autism spectrum disorders. For this reason 60 boy students with autism disorder (age 8–10 years old) were assigned to four groups with no differences in age, BMD, calcium intake, and physical activity: exercise groups with or without calcium supplementation (Ex+Ca+ and Ex+Ca−) and non-exercise groups with or without calcium supplementation (Ex−Ca+ and Ex−Ca−). The intervention involved 50 min of weight bearing exercise performed 3 sessions a week and/or the addition of dietary calcium rich food using enriched cow milk with vitamin D containing 250 mg calcium per serving, over 6 months. Paired-samples t test, one way ANOVA analysis, and Tukey tests were used to determine the main and combined effects of training and calcium on BMD. All groups showed greater femoral neck BMD after 6 months. The increase in femoral neck BMD in the Ex+Ca+ group was 14.04% greater than increase in the Ex+Ca− group (P < 0.05). Apparently, the effect of training was greater than calcium intake because the Ex+Ca− group achieved 4.71% greater BMD than Ex−Ca+ group (P < 0.05). In this study, all experimental groups had greater BMD than the control group (Ex−Ca−) (P < 0.05). In these participants, additional weight bearing exercise and calcium supplementation resulted in a greater increase in BMD than controls at the loaded site (femoral neck). These results help to provide more evidence for public health organizations to deal with both exercise and nutrition issues in children with autism disorder for the achievement and of peak BMD.

Titre : Serum vitamin D and folate levels in children with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Ça?atay U?UR, Auteur ; Cihat Ka?an GÜRKAN, Auteur Article en page(s) : p.1641-1647 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Vitamin D Calcium Folate Index. décimale : PER Périodiques Résumé : Abstract It has recently proposed that vitamin D and folate may be involved in the aetiology of autism. We investigated the serum levels of vitamin D, calcium (Ca), phosphorus (P), alkaline phosphatase (ALP) and folate in 54 young children, aged 3–8 years, with autism spectrum disorders (ASD) and in 54 age and gender matched normal controls. Vitamin D, Ca, P, ALP and folate levels in children with ASD were not different from control group. The correlational analysis in children with ASD revealed that Aberrant Behaviour Checklist, Autism Behaviour Checklist, and Childhood Autism Rating Scale scores and the level of cognitive development were not correlated with these laboratory findings. Our findings do not support the idea that serum levels of vitamin D and folate might be low in children with ASD. Nevertheless, it is possible that vitamin D and folate deficiency may be playing a role in development of ASD at earlier ages or during prenatal period.

We performed a case-controlled cross-sectional analysis to assess vitamin D levels in 83 children with ASD aged less than 8 years old compared to 106 healthy controls. In addition, the association between vitamin D deficiencies and gastrointestinal (GI) complains and electroencephalogram (EEG) abnormalities commonly found in children with ASD was investigated. Vitamin D levels in ASD patients were significantly lower. Also, Vitamin D levels in ASD patients had significant correlation with GI complains, but no correlation between vitamin D levels and Ca(2+)or EEG abnormalities was detected. These data suggest a possible role for vitamin D deficiency in the pathophysiology of ASD.

Titre : The association of serum 25-hydroxyvitamin D3 and D2 with depressive symptoms in childhood – a prospective cohort study Type de document : Texte imprimé et/ou numérique Auteurs : Anna-Maija TOLPPANEN, Auteur ; Adrian SAYERS, Auteur ; William D. FRASER, Auteur ; Glyn LEWIS, Auteur ; Stanley ZAMMIT, Auteur ; Debbie A. LAWLOR, Auteur Année de publication : 2012 Article en page(s) : p.757-766 Langues : Anglais (eng) Mots-clés : 25-Hydroxyvitamin D calcium parathyroid hormone child depression ALSPAC Index. décimale : PER Périodiques Résumé : Background: Depression in adolescence is common and early onset predicts worse outcome in adulthood. Studies in adults have suggested a link between higher total 25-hydroxyvitamin D [25(OH)D] concentrations and lower risk of depression.
Objectives: To investigate (a) the association between serum 25(OH)D2 and 25(OH)D3 concentrations and depressive symptoms in children, and (b) whether the associations of 25(OH)D2 and 25(OH)D3 are different from, and independent of, each other.
Methods: Prospective cohort study with serum 25(OH)D2 and 25(OH)D3 concentrations measured at mean age of 9.8 years and depressive symptoms assessed with the Mood and Feelings Questionnaire by a trained interviewer at the mean ages of 10.6 years (n = 2,759) and 13.8 years (n = 2,752).
Results: Higher concentrations of 25(OH)D3 assessed at mean age 9.8 years were associated with lower levels of depressive symptoms at age 13.8 years [adjusted risk ratio (RR; 95% confidence interval (CI)): 0.90 (0.86–0.95)], but not at age 10.6 years [adjusted RR (95% CI): 0.98 (0.93–1.03)] and with increased odds of decreasing symptoms between age 10.6 and 13.8 years [adjusted RR (95% CI): 1.08 (1.01–1.16)]. Serum 25(OH)D2 concentrations were not associated with depressive symptoms.
Conclusions: This is the first study in children to suggest that the association between 25(OH)D3 concentrations and depression emerges in childhood. The association is independent of a wide range of potential confounding factors, and appears to be stronger with greater time separation between assessment of 25(OH)D3 and assessment of depressive symptoms. Confirmation of our findings in large prospective studies and trials would be valuable.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2011.02518.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=166
