BACKGROUND The widespread use of nutritional supplements among athletes is poorly understood. The prevalence of supplement intake and users' knowledge have been researched independently leading to useful, but disconnected, information on supplement use. METHODS The 'UK Sport 2005 Drug Free Survey' data (n = 874) were re-analysed using association [chi2] and 'strength of association' tests [ph...

Haematological indices of iron deficiency and serum ferritin concentrations were compared in 42 women complaining of menorrhagia and in 34 with normal menstrual loss. No significant differences in haemoglobin concentration, mean corpuscular volume, or mean corpuscular haemoglobin concentration were found between the two groups. Serum ferritin concentrations were significantly lower (p less than...

A woman (70-years) with a history of iron deficiency anemia and chronic kidney disease presented with two weeks of abdominal pain. Upper endoscopy demonstrated the gastric and duodenal mucosa was black and speckled consistent with diagnosis of pseudomelanosis. Biopsies showed pigment-laden macrophages in the lamina propria, which stained positive for iron and Masson-Fontana trichrome stain cons...

BACKGROUND Iron deficiency is common during pregnancy. Experimental animal studies suggest that it increases cardiovascular risk in the offspring. OBJECTIVE To examine the relationship between maternal pregnancy dietary and supplement iron intake and hemoglobin, with offspring's arterial stiffness (measured by carotid-radial pulse wave velocity), endothelial function (measured by brachial art...

OBJECTIVE This study aimed to assess the contribution of postnatal services to the risk of neonatal mortality, and the relative contributions of antenatal iron/folic acid supplements and postnatal care in preventing neonatal mortality in Indonesia. DESIGN Retrospective cohort study. SETTING AND PARTICIPANTS Data used in this study were the 2002-2007 Indonesia Demographic and Health Surveys,...

OBJECTIVE To examine the determining factors of anemia and iron deficiency in children attending two day care centers in the town of Pontal, southeast of Brazil. METHODS Cross-sectional study was conducted in 192 children aged 12 to 72 months. Personal data (age, sex, use of medicinal iron supplements, duration of breast-feeding, type of delivery, prenatal care, weight, and height), and socio...

This study investigated whether athletes meet micronutrient recommendations and whether the adequacy of their intake is related to the use of dietary supplements, sport nutrition products or a combination. Micronutrient intakes of 553 Dutch (sub-) elite athletes were assessed using web-based 24-h dietary recalls with accompanying nutritional supplement questionnaires. In the majority of both us...

This study compares the eating habits and consumption of natural and fortified iron sources in pregnant and reproductive aged women. This cross-sectional study was developed in a health center located in São Paulo, SP, Brazil. We studied 61 women, of which 30 were pregnant. A food frequency questionnaire and a 24-hour recall instrument were used. The main natural sources of iron were beans and ...

The effects of a single intramuscular iron dose, 10mg, to pregnant rats on Day of pregnancy, on the outcome of pregnancy, with respect to foetal weight and mother's immune function has been investigated. Despite significantly elevated hepatic iron stores after iron supplementation in pregnant rats this had no significant effect upon blood haemoglobin or transferrin saturation levels. However th...

Asymptomatic iron deficiency is frequently observed in competitive athletes and an impaired iron metabolism may lead to abnormal haemoglobin and myoglobin production limiting endurance capacity. Iron supplementation could improve blood biochemical measures and increases work capacity but the use of iron supplements should be a judicious choice based on a careful hematological evaluation since a...
