“…The finding that more boys than girls were iron deficient is difficult to explain since there are no sex differences in iron requirements in the preschool age group. It has recently been shown that obesity and being overweight are associated with greater risk of ID, perhaps due to low diet quality, increased iron requirement due to higher blood volume as well as decreased iron absorption induced by chronic low-grade inflammation (40)(41)(42)(43)(44) . In another analysis of the Inuit Child Health Survey, boys were noted to have higher BMI-for-age Z-scores than girls (27) .…”

Objective: To report the prevalence rates and correlates for anaemia, iron deficiency (ID) and iron-deficiency anaemia (IDA) among Inuit preschool-aged children. Design: A cross-sectional study assessed iron intake, demographic information, medical history, anthropometrics, Hb, ferritin, C-reactive protein and antibodies to Helicobacter pylori. Setting: Sixteen selected Inuit communities in Nunavut Territory, Canada. Subjects: Inuit (n 388) aged 3-5 years randomly recruited from communities. Results: Anaemia (3-4 years: Hb , 110 g/l; 5 years: Hb , 115 g/l) was prevalent in 16?8 % of children. The prevalence of ID (ferritin , 12 mg/l) was 18?0 % and that of IDA was 5?4 %. When ID was defined as ferritin ,10 mg/l, 10?8 % of children were iron deficient and 3?3 % had IDA. In multiple logistic regression, boys were more likely to be iron deficient (OR 5 2?28, 95 % CI 1?17, 8?25), but no other risk factor emerged for ID. Three-to 4-year-olds were less likely than 5-year-olds to have anaemia from causes other than ID (OR 5 0?11, 95 % CI 0?08, 0?58). Anaemia from other causes was more common among children residing in crowded homes (OR 5 2?30, 95 % CI 1?37, 12?31) and those treated for past-year ear infection (OR 5 1?35, 95 % CI 1?05, 7?21). Conclusions: The low prevalence of ID and IDA is encouraging, but efforts are still needed to reduce rates as they continue to be higher than general population rates. Household crowding and infections may contribute to anaemia and warrant further research.

-Trace elements and minerals influence the pathogenesis of obesity and diabetes and their complications, mainly through their involvement in peroxidation and inflammation. On the other hand, peroxidation and inflammation are liable to alter the metabolism of these nutrients, which should be taken into account when assessing their status. Milk products are capable of preventing iron-induced peroxidation and the metabolic complications of the diseases. Calcium, especially cow milk calcium, seems to be capable of preventing the development of adipocytes and obesity complications (inflammation, hypertension, and insulin resistance), mainly through interactions with vitamin D metabolism. These observations give an opportunity to influence the course of obesity by dietetic advices.calcium / trace element / iron / obesity / diabetes / peroxidationRésumé -Rôle des oligo-éléments et du calcium dans les formes de diabète et l'obésité et leurs complications. Effet protecteur des produits laitiers. Les oligo-éléments et les minéraux jouent un rôle dans la genèse de l'obésité, du diabète et de leurs complications métaboliques, en particulier par leur implications dans les phénomènes inflammatoires et la peroxydation. Ces derniers pouvant modifier par eux-mêmes le métabolisme des minéraux, il faut en tenir compte dans l'appréciation de leur statut. Les produits laitiers préviennent la peroxydation liée au fer (rôle principalement joué par les protéines) et les complications métaboliques : ainsi, le calcium, surtout d'origine laitière, interagit avec la vitamine D pour prévenir la différenciation des adipocytes, la lipogenèse et favoriser la production de chaleur ; il lutte contre l'inflammation, l'hypertension et la résistance à l'insuline, composants majeurs du risque cardio-vasculaire. Ces données ouvrent la voie à une intervention non médicamenteuse, sur le long terme, des maladies de civilisation.calcium / oligo-éléments / fer / obésité / diabète / peroxydation *Corresponding author (通讯作者): dbougle@wanadoo.fr Dairy Sci.

“…The mechanism underlying these associations is poorly understood. Leptin, the protein product of the ob gene, is a hormone that is secreted primarily by adipose tissue and is responsible for regulating feeding behavior (4)(5)(6)(7)(8). Dongiovanni et al found that serum leptin is decreased in mice fed with 2% carbonyl iron diet, while this might be a secondary effect of fat-mass loss (9).…”
