0	Less than 1 time per week	17	72.764 ± 5.883	70.875
1	1 time per week	24	73.387 ± 7.238	74.722	0.0680–1
2	2 times per week	21	73.516 ± 8.845	72.810	0.3290–2, 0.3121–2

n = 76; *p < 0.05; **p < 0.01; ***p < 0.001. ^c non-adjusted for any demographic variables ^d adjusted for age, sex, BMI, length of education, annual income, tenure, occupation, and GM-BHQ by ANCOVA method. ^0–1 p-value derived from comparison between “less than 1 time” and “1 time” by ANCOVA method. ^0–2 p-value derived from comparison between “less than 1 time” and “2 times” by ANCOVA method. ^0–3 p-value derived from comparison between “less than 1 time” and “more than 2 times” by ANCOVA method. ^1–2 p-value derived from comparison between “1 time” and “2 times” by ANCOVA method. ^1–3 p-value derived from comparison between “1 time” and “more than 2 times” by ANCOVA method. ^2–3 p-value derived from comparison between “2 times” and “more than 2 times” by ANCOVA method.
