Can Vitamin C Intake and Physical Activity Individually and Jointly Lower Inflammation in Chronically Infected Populations? Insights from NHANES 2005–2018
Abstract
Background:
Systemic
immune-inflammation
is
a
key
contributor
to
chronic
disease
pathogenesis.
Whether
vitamin
C
intake
and
physical
activity
influence
inflammatory
status
in
individuals
with
latent
viral
infections
remains
unclear.
Methods:
We
conducted
cross-sectional
analysis
of
33,590
U.S.
adults
from
NHANES
2005–2018.
Vitamin

assessed
by
two
24-hour
dietary
recalls;
self-reported.
The

secondary
outcomes
including
NLR,
PLR,
PPN,
PC,
NC,
LC.
Multivariable
linear

models
adjusted
for
sociodemographic

covariates.
Analyses

Results:
