Danish legislation regarding food fortification has been very restrictive resulting in few fortified food items on the Danish market. Folate and vitamin B12 deficiency is thought to be common due to inadequate intakes but little is known about the actual prevalence of low serum folate and vitamin B12 in the general population. The aim of the present study was to evaluate the folate and vitamin ...

OBJECTIVE To examine the prevalence of low serum folate and vitamin B12, in association with elevated serum homocysteine, in a representative sample of older Australians. METHODS During 1997-2000, 3,508 persons aged 50+ years were examined in a population-based cohort study conducted in two postcodes, west of Sydney, Australia. Of these, 2,901 participants (82.7%) provided fasting blood for e...

Background: Vitamin B12 and folate defi ciency can cause anemia which may lead growth and development impairments. This study was aimed to determine serum folate levels among infants aged 6–8 months and the relation to infants’ nutritional indicators and maternal knowledge-attitude-practice about infant feeding. Methods: A cross–sectional design was implemented in infants aged 6–8 months and th...

1. There are conflicting reports regarding the effect of oral contraceptives on serum and erythrocyte folate concentrations and on folate absorption. A detailed study of this problem was therefore undertaken. 2. It was first ascertained that there was no significant variation in serum folate concentrations at different stages in the normal menstrual cycle. 3. No significant difference was found...

BACKGROUND Newfoundland has one of the highest rates of neural tube defects in North America. Given the association between low maternal folic acid levels and neural tube defects, a cross-sectional study was conducted to obtain base-line data on the folate and vitamin B12 status of a sample of women in Newfoundland who were pregnant. METHODS Blood samples were collected between August 1996 an...

The aim of this study was to analyse the hematologic status in patients with recurrent oral ulceration (ROU). Twenty-three patients with ROU and 19 control subjects were examined consecutively for hematological abnormalities including serum folate, red cell folate and vitamin B12 levels. Their complete blood counts, hemoglobin typing, serum and red cell folate and serum vitamin B12 levels were ...

Of the 85 female marathon runners examined in this study, 14 (16%) had serum ferritin levels below 40 ng/ml but only two (2%) had iron deficiency anaemia (haemoglobin below 12 g/dl); 28 (33%) had serum folate levels below 4.8 ng/ml and of these two (2%) had haemoglobin levels below 12 g/dl and 13 (15%) had mean corpuscular volumes greater than 95 fl. One week after treatment with oral folate (5...

The folate status and dietary folate intake of Taiwanese schoolchildren was investigated by analysis of both serum and red blood cell (RBC) folate levels and dietary folate intake in 1105 boys and 958 girls aged 6-13 years sampled from the Nutrition and Health Survey in Taiwan Elementary School Children 2001-2002 (NAHSIT Children 2001-2002). Mean serum folate levels were 18.3+/-8.8 nmol/L (8.1+...

AIM To study the effect of folate treatment on hyperhomocysteinaemia and the effect of 5,10-methylenetetrahydrofolate reductase (MTHFR) gene polymorphism on total homocysteine and folate concentrations after renal transplantation. METHODS A total of 30 transplanted children and adolescents were investigated for total homocysteine and folate serum concentrations before and after folate treatme...

A prospective study of folate metabolism has been conducted in outpatient anticonvulsant-treated epileptics on 68 occasions. An attempt was made to compare the relative sensitivities of serum and red cell measurements of folic acid, lactic dehydrogenase (LD), and 2 hydroxybutyric dehydrogenase (2HBD). The most sensitive indices of folate deficiency appeared to be serum folate, red cell LD, red ...
