Table 3 Factor loading of three food patterns among Chinese urban elders with different gastrointestinal symptom rating scale scores (n = 688)

Food pattern1		GSRS score2			P value
		≤ 17	18-20	≥ 21
Pattern 1	Median (25th, 75th)	0.0. (-0.32, 0.80)	0.34 (-0.30, 0.83)	0.36 (-0.29, 0.84)	0.200
	Adjusted OR (95%CI)3	Ref.	0.09 (-0.10, 0.27)	0.07 (-0.03, 0.16)
Pattern 2	Median (25th, 75th)	-0.10 (-0.70, 0.45)	-0.02 (-0.47, 0.44)	-0.18 (-0.75, 0.56)	0.412
	Adjusted OR (95%CI)3	Ref.	0.05 (-0.13, 0.23)	-0.01 (-0.10, 0.08)
Pattern 3	Median (25th, 75th)	0.14 (-0.54, 0.65)	-0.07 (-0.62, 0.57)	0.24 (-0.62, 0.81)	0.199
	Adjusted OR (95%CI)3	Ref.	0.08 (-0.10, 0.25)	0.07 (-0.02, 0.16)

¹The first food pattern was characterized by high intake of salt and tea; the second pattern was characterized by more frequent intake of tubers, fruits, aquatic products, and soybean and nuts; the last pattern was associated with high intake of cereal, vegetables, and meat.

²The total GSRS score was divided into three groups according to the tertiles.

³The linear regression was performed and adjusted for gender, education level, and family income. GSRS: Gastrointestinal symptom rating scale; OR: Odds ratio; CI: Confidence interval.
