| Summary: | Introduction
Some elderly people in China prefer sun-cured tobacco to cigarettes,
and the composition of sun-cured tobacco and cigarettes is inconsistent. The
influence of cigarettes on the cognitive function of COPD patients has been widely
reported, but the research on sun-cured tobacco is relatively rare. Our study
explored the association of sun-cured tobacco and cigarette use with cognitive
decline in COPD patients.
Methods
This was a cross-sectional study. A total of 401 COPD patients were
included, and 190, 103, and 108 participants were included in non-smoking,
cigarette-smoking, and sun-cured tobacco groups, respectively. We evaluated the
global cognitive function using the Beijing version of the Montreal Cognitive
Assessment, verbal fluency function using an animal fluency test, and memory
function using ten unrelated words.
Results
The participants of both cigarette-smoking (AOR=11.18; 95% CI: 1.28–
97.5) and sun-cured tobacco (AOR=10.46; 95% CI: 1.14–96.4) groups were more
likely to develop mild cognitive impairment compared to the non-smoking group.
The mean z scores of global cognitive function, verbal fluency, and memory
were lower in cigarette-smoking and sun-cured tobacco groups than those in a
non-smoking group; Multivariable linear regression showed that global cognitive
function (β= -0.61; 95% CI: -1.04 – -0.18; and β= -0.48; 95% CI: -0.91 – -0.05)
and verbal fluency (β= -0.79; 95% CI: -1.33 – -0.26; and β= -0.69; 95% CI:
-1.23 – -0.16) of the sun-cured tobacco group and the cigarette-smoking group
were significantly lower than those of the non-smoking group when adjusting for
demographic and disease-related characteristics. However, there was no significant
difference between the cigarette-smoking and sun-cured tobacco groups in global
cognitive function, verbal fluency, and memory.
Conclusions
Compared with non-smokers, the use of cigarettes and sun-cured
tobacco may damage the cognitive function of COPD patients, especially in global
cognitive function and verbal fluency. |
