Abstract

Canadian children have been shown to be not meeting the revised (2010) dietary recommended intake (DRI) for vitamin D through diet alone. However, no study has evaluated whether diet and supplementation together are supporting Canadian children in meeting the DRIs for vitamin D intake. This study assessed the adequacy of vitamin D intake through diet and supplements among Albertan children and the determinants of meeting dietary guidelines. 2686 grade 5 students aged 10 to 11 years in Alberta, Canada were surveyed. We hypothesized that less than 50% of children would meet the DRI. Vitamin D intake from diet and supplements was assessed using a food frequency questionnaire. The adequacy of vitamin D intake was estimated using the Estimated Average Requirement (EAR) of 400 IU (International Units) and Recommended Dietary Allowance (RDA) of 600 IU. Random effect multiple logistic regression was used to identify correlates of meeting DRIs. Forty five percent of children met the EAR and 22% met the RDA for vitamin D. When vitamin D intake from diet alone was considered, only 16% and 2% met the EAR and RDA, respectively. Parental education, household income and physical activity were positively correlated with meeting DRIs, and stude...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
