Table 3. Association between nutritional status at baseline based on the NSIC and functional capacity decline at the 2-year follow-up among the 536 subjects.

	ADL decline (n = 24)/ Non-ADL decline (n = 512)		IADL decline (n = 68)/ Non-IADL decline (n = 468)
	OR (95%CI)	P value	OR (95%CI)	P value
Group
Low nutritional risk	1.0 (reference)		1.0 (reference)
Moderate nutritional risk	3.00 (0.96, 9.35)	0.058	1.45 (0.74, 2.86)	0.279
High nutritional risk	4.96 (1.59, 15.5)	0.006	2.58 (1.31, 5.06)	0.006

NSIC, Nutrition Screening Initiative Checklist; ADL, activities of daily living; IADL, instrumental ADL; OR, odds ratio; CI, confidence interval.

Logistic regression analysis, adjusted for age, sex, body mass index, hypertension, cerebrovascular diseases, and smoking habit and using low nutritional risk as the reference, was used to determine odds ratios and 95% CIs. ADL and IADL at follow-up were assigned as the dependent variable, and baseline nutritional status according to the NSIC was assigned as the independent variable.
