Table 3.

Risks of Abdominal Obesity Chewing Difficulty, and Possessing Both on Cognitive Impairment, and Risk of Chewing Difficulty on Cognitive Impairment According to Abdominal Obesity.

Variables	Cognitive impairment OR (95% CI)	P-value
Abdominal obesity (N = 380)
No abdominal obesity (ABSI <.085)	1.00	-
Abdominal obesity a	1.54 (.91–2.62)	.110
Chewing ability (N = 380)
Normal chewing ability (chewing difficulty = 0)	1.00	-
Chewing difficulty b	1.87 (1.10–3.18)	.021
Abdominal obesity and chewing ability (N = 380)
No abdominal obesity with normal chewing ability	1.00	-
Abdominal obesity with chewing difficulty	2.22 (1.18–4.17)	.014

Note: Risks were demonstrated using OR (95% CI) and conducted by a general logistic regression model, taking ‘normal cognition’ group as reference, adjusting for age, sex, education, past smoking history, past drinking history, cerebrovascular disease history and heart disease history.
