Exercise and/or Dietary Varieties and Incidence of Frailty in Community-Dwelling Older Women: A 2-Year Cohort Study.

摘要: Exercise and dietary habits rich in variety may reduce the risk of frailty incident, but such association remains unexamined. This study aimed to examine longitudinal associations between exercise and/or varieties incidence older women. A 2-year population-based prospective cohort study. Six hundred four community-dwelling Japanese women aged ≥75 years with non-frailty at baseline survey. Frailty was assessed using Fried’s criteria composed shrinking, weakness, slowness, low activity, exhaustion both follow-up surveys. incident defined as presence =3 components At baseline, information about were obtained from all participants through a face-to-face interview. Participants grouped into two categories, high (=2) (<2) varieties, by number participations 17 types. By variety, Dietary Variety Score (range, 0 10), two, (=4 points) (<4 varieties. Binary logistic regression analyses applied obtain adjusted odds ratios (ORs) 95% confident intervals (CIs) 4 groups (low-exercise low-dietary [low EV + DV] reference; low-exercise high-dietary DV]; high-exercise [high DV]). rate 9.3% over period. Incidence rates follows: 23.7%, 10.1%, 6.5%, 7.7% DV, DV groups, respectively. After adjustment for covariates, only group associated significantly lower OR (0.38; CI 0.15–0.92) compared group. Higher diet frailty. Thus, combination variety-rich program be useful preventing
