Studies of B vitamins and related genetic factors in relation to bone health in older adults

Subject: Biomedical Sciences


Summary

Osteoporosis is a major public health problem among older adults throughout the world. Given the significant healthcare costs of treating osteoporosis and its consequences, new strategies to maintain better bone health in older age are urgently needed. Vitamin D and calcium have well established preventive roles against osteoporosis, but other nutritional factors are emerging. Recent evidence suggests important protective roles for folate and the metabolically related B vitamins (i.e. vitamins B12, B6 and B2) in bone, through a separate mechanism - involving one carbon metabolism - that is unrelated to vitamin D (Clarke et al 2014; Bailey et al 2015). Notably, recent work from the nutrition team at Ulster University in collaboration with partners in Trinity College Dublin (TCD) showed that older people with low B-vitamin intakes or with a genetic variant folate metabolism were at significantly higher risk of osteoporosis.

This PhD project builds on this evidence, and will involve conducting human studies on B vitamins in relation to bone health outcomes in older adults. The project will form part of the ongoing TUDA study, the largest cohorts of its kind in Europe, providing comprehensive nutrition and health data on 5200 older adults recruited from North and South of Ireland. Embedded within the TUDA study is the OptiAGE project which specifically focusses on bone health and extends the existing collaboration of Ulster with TCD to also include UCD. Working as part of the TUDA-OptiAge team, this PhD project will involve conducting human trials in older people to optimise B vitamin status with the potential to influence bone mineral density.

The overall aim will be to investigate the role of B vitamins in bone in older adults. Methods: TUDA study participants will be screened and those identified with low B-vitamin intakes or genetic variation in folate metabolism will be invited to participate in intervention trials. These will include a 2-year trial of B vitamins supplements and shorter-term food trials to test the effectiveness of a newly developed B-vitamin fortified drink in older adults at-risk of sub-optimal B-vitamin status.  The student will gain experience in running human trials, analysing results using appropriate statistical methods and in the use of a range of relevant laboratory measures (related to B vitamin status and bone biomarkers), as well as performing and interpreting bone mineral density (BMD) measurements in participants using Dual energy X-ray absorptiometry (DXA) bone scans (gold standard measurement for osteoporosis diagnosis). The student will need to work closely with the wider TUDA team at Ulster, interact with our external collaborators at TCD and UCD, and participate in meetings in Dublin and Norway as required.

This project will be based at Ulster's Nutrition Innovation Centre for Food and Health (NICHE).
