Abstract
We aimed to investigate whether frequencies of protein-rich food intake were associated with frailty among older Japanese adults. A cross-sectional study was conducted in 2011 among 3843 men and 4331 women in a population-based cohort of Kameoka city, Kyoto Prefecture, Japan. Frailty was assessed by the weighted score based on the 25-item Kihon-Checklist. The frequency of protein-rich food intake was examined as “seafood”, “meat”, “dairy products”, “eggs”, and “soy products”. The outcome of frailty was analyzed with a multiple logistic regression model using the frequency of protein-rich food intake. When compared to the first quartile, it was observed that there was a significant association between the lower adjusted prevalence ratio (PR) for frailty and the frequency of seafood intake in the fourth quartile among men (PR 0.64, 95% confidence interval (CI), 0.42, 0.99) and from the second quartile to the third quartile among women (PR 0.61, 95% CI, 0.43, 0.85; PR 0.64, 95% CI, 0.46, 0.91). The frequency of dairy products intake in the third quartile among women was significantly associated with a lower PR for frailty (p-value = 0.013). Our findings suggest that the consumption of seafood and dairy products may help older adults in maintaining their independence.
Highlights
It is estimated that Japan has the highest proportion of elderly citizens globally
The receiver operating characteristic (ROC) curve analysis with a total β score of 3.80 as the cutoff point for frailty resulted in an area under the curve (AUC) of 0.86, sensitivity of 89.4%, and specificity of 81.6%
2.1 times/day in the fourth quartile for men; 1.1–2.2 times/day in the third quartile for women) and dairy products in women (1.0–1.9 times/day in the third quartile) resulted in a 0.61–0.69-fold lower prevalence ratio for frailty compared to the lowest intake frequency group in older Japanese adults
Summary
It is estimated that Japan has the highest proportion of elderly citizens globally. The JapaneseCensus Bureau approximates that, as of 2015, 27% of the Japanese population is aged 65 years and above [1]. It is estimated that Japan has the highest proportion of elderly citizens globally. In a recent review article, three studies that included older Japanese populations reported on the significant association between higher protein intake and a lower prevalence of frailty; there was a null association in two other studies [5]. It is still controversial whether there is a significant association between protein-rich food intake (e.g., seafood, meat, dairy products, egg, and soy products) and frailty status in older adults
