Abstract EN
The increase of ageing population has raised public attention on the concept of successful ageing.
Studies have shown that vitamin D, telomere length, and brain-derived neurotrophic factor (BDNF) have been associated with cognitive function.
Therefore, this study aimed to identify neuroprotective factors for cognitive decline in different ageing groups.
A total of 300 older adults aged 60 years and above were recruited in this population based cross-sectional study.
Participants were categorized into three groups: mild cognitive impairment (MCI) (n=100), usual ageing (UA) (n=100), and successful ageing (SA) (n=100).
Dietary vitamin D intake was assessed through Diet History Questionnaire (DHQ).
Out of the 300 participants, only 150 were subjected to fasting blood sample collection.
These samples were used for serum vitamin D and plasma BDNF measurements.
Whole blood telomere length was measured using RT-PCR method.
The results show that the reduction of the risk of MCI was achieved by higher serum vitamin D level (OR: 0.96, 95% CI: 0.92–0.99, p<0.05), higher plasma BDNF level (OR: 0.51, 95% CI: 0.30–0.88, p<0.05), and longer telomere (OR: 0.97, 95% CI: 0.95–0.99, p<0.001).
In conclusion, participants with higher vitamin D level, higher BDNF level, and longer telomere length were more likely to age successfully.
