ASSOCIATIONS OF LIFESTYLE FACTORS AND 25 HYDROXYVITAMIN D ACCORDING TO COGNITVE STATUS AMONG OLDER ADULTS
Lifestyle can affect vitamin D status in old adults, however, it is not known whether lifestyle is associated with vitamin D in old adults with mild cognitive impairment (MCI) or dementia. In this cross-sectional study we examined associations between lifestyle and serum-25-hydroxyvitamin D (25OHD)...

According to multivariate statistics, cod liver oil (7.1 - 9.1nmol/L, P<0.001) and dietary supplements (4.5–11.1nmol/L, P<0.001) were associated with higher 25OHD in all three groups.

Lifestyle can affect vitamin D status in old adults, however, it is not known whether lifestyle is associated with vitamin D in old adults with mild cognitive impairment (MCI) or dementia. In this cross-sectional study we examined associations between lifestyle and serum-25-hydroxyvitamin D (25OHD) among old adults (65-96yrs) with dementia (n=393, 6.8%), MCI (n=550, 9.5%) and normal cognitive status (NCS) (n=4569, 79.2%) from Reykjavik, Iceland. Information on 25OHD, physical activity (PA), cod liver oil, dietary supplements, anthropometrics, smoking and alcohol were collected. 25OHD was significantly lower in demented (53.8nmol/L) and in MCI (55.8nmol/L) than in healthy participants (57.6nmol/L). According to multivariate statistics, cod liver oil (7.1 - 9.1nmol/L, P<0.001) and dietary supplements (4.5–11.1nmol/L, P<0.001) were associated with higher 25OHD in all three groups. However, physical activity (6.6nmol/L, P<0.001), BMI<30kg/m2 (5.2nmol/L, P<0.001), non-smoking (4.8nmol/L, P<0.001) and alcohol consumption (2.5nmol/L,P<0.001) were related to 25OHD in NCS only but not in participants with dementia or MCI. Summing up, it shows that good lifestyle is associated with higher 25OHD in demented (18.2nmol/L), MCI (16.2nmol/L) and healthy participants (32.5nmol/L). Lifestyle is an important determinant of 25OHD among older adults.
