J-CHS, Japanese version of the Cardiovascular Health Study [27]; OR, odds ratio; CI, confidence interval.
1)Numbers of subjects. Total: 267, non-frailty, 167; prefrailty, 100; bread and beverages, 54; vegetables and dairy products, 113; rice and fish and shellfish, 100.
2)Adjusted for age (yrs) as continuous variables (n = 267), living alone (yes: n = 53 or no: n = 214), current smoker (yes: n = 15 or no: n = 252), and alcohol drinking (yes: n = 108 or no: n = 159).
