Background: Although obesity and health-related quality of
life (HRQOL) in elderly are well known to be associated
with obesity and sitting time, it is unclear whether effect of
sedentary lifestyle on HRQOL is affected by
body mass index (BMI) or not. So we analyzed the
relationship between sitting time and HRQOL according to
BMI groups in elderly Korean.
Methods: Participants aged over 60 from the 6th Korea
National Health and Nutrition Examination Survey (2014
and 2015) were included. Participants were classified as
normal weight and overweight/obese groups. Mean
sitting times were compared between groups according to
the EuroQol 5 dimension (EQ-5D) And logistic regression
analyses were performed.
Results: Men with mobility, usual activity, or pain/discomfort
domain problem had longer sitting time. Women
with a problem in every domain had longer sitting time.
Overweight/obese women with problem showed longer
sitting time. Odds ratios (ORs) of mobility, usual activity,
pain or discomfort, and low EQ-5D score domain were
increased regardless of BMI groups in men. But, ORs of all
domains were increased only in overweight/obese
group in women.
Conclusions: In elderly Korean, prolonged sitting time
associated with decreased HRQOL. Impaired HRQOL is
associated with increased sitting time regardless of BMI in
men. But only overweight/obese group showed association
between prolonged sitting time and impaired HRQOL in
women. These results represents that decrease
in quality of life according to the increase of the sitting time
differs according to the BMI in elderly Korean
women.
