Vitamin D across the lifecycle to inform nutritional policies

Subject: Biomedical Sciences


Summary

Vitamin D is essential for calcium and phosphate metabolism and plays a major role in bone health(1).  Research has also shown that vitamin D has other non-skeletal roles including muscle function, immune regulation, brain development and anti-cancer effects(2).  The primary source of vitamin D is via sun exposure, with limited rich dietary sources available.  Ensuring optimal vitamin D status is now a recognised worldwide public health problem(3) and strategies are needed to reduce deficiency and insufficiency as well as prevent excess intake.

In July 2016, the UK Scientific Advisory Committee on Nutrition (SACN) published new guidelines on vitamin D, recommending a reference nutrient intake (RNI) of 10µg of vitamin D per day throughout the year for everyone in the population aged 4 years and older(4).  This intake refers to all dietary sources of vitamin D including: natural food sources, fortified foods and supplements.

Currently there is a paucity of data from randomised controlled trials to inform specific dietary requirements for young children. A safe intake of between 8.5 and 10µg vitamin D/day is supported for this age group albeit no clear guidance exists. Factors such as sun-exposure, diet (including fortififed foods) and optimal need to be considered.

The aim of this proposed PhD is to investigate factors predicting vitamin D status across the lifecycle to inform nutritional policies. The main objectives of this PhD research will be met using a range of research methods, to:

*systematically review the literature to critically evaluate changes in vitamin D status and intake across the lifecycle, with a particular emphasis on the current evidence in children

*determine factors predicting status across the lifecycle (using all available ‘biobank’ data from previous studies)

*using Geographic Information System (GIS) technology to map vitamin D status of a sample of the population and identify spatial variations that may exist.

*conduct a randomised controlled trial in children to establish the distribution of dietary vitamin D required to maintain vitamin D status throughout wintertime to inform dietary guidelines

The proposed research will extend the vitamin D research expertise of NICHE, building on the existing evidence-base and directly informing the REF Impact Case Study on ‘Vitamin D and Health’ for Biomedical Sciences.

The PhD researcher appointed to the project will be given every opportunity to maximise on training by participating in relevant workshops, specialist skills sessions, relevant online courses, PhD researcher initiatives and personal development activities organised by the Doctoral College. In addition, the student will be expected and strongly encouraged to prepare and present their research findings when appropriate at national and international conferences.
