Popis: The antioxidant vitamin E (&alpha
tocopherol, &alpha
TOH) protects lipids from oxidation by reactive oxygen species. We hypothesized that lifestyle factors associate with vitamin E metabolism marked by urinary &alpha
tocopheronolactone hydroquinone (&alpha
TLHQ) and &alpha
carboxymethyl-hydroxychroman (&alpha
CEHC levels), as potential reflection of lipid oxidation. We conducted a cross-sectional study in the Netherlands Epidemiology of Obesity Study. Serum &alpha
TOH, and urinary &alpha
TLHQ and &alpha
CEHC were quantified by liquid chromatography coupled with tandem mass spectrometry. Information on the lifestyle factors (sleep, physical activity (PA), smoking and alcohol) were collected through questionnaires. Multivariable linear regression analyses were performed to assess the associations between the lifestyle factors and &alpha
TOH measures. A total of 530 participants (46% men) were included with mean (SD) age of 56 (6) years. Of the examined lifestyle factors, only poor sleep was associated with a higher serum &alpha
TOH (mean difference: 4% (95% CI: 1, 7%)). Current smoking was associated with higher urinary &alpha
CEHC (32%: (14%, 53%)), with evidence of a dose&ndash
response relationship with smoking intensity (low pack years, 24% (2, 52%)
high pack years, 55% (25, 93%)). Moderate physical activity was associated with a lower &alpha
TLHQ relative to &alpha
CEHC (&minus
17%: (&minus
26, &minus
6%), compared with low PA). Only specific lifestyle factors associate with vitamin E metabolism. Examining serum &alpha
TOH does not provide complete insight in vitamin E antioxidant capacity.
