The Relationship between Psychological Distress and Physical Frailty in Japanese Community-Dwelling Older Adults: A Cross-Sectional Study

摘要

BACKGROUND: Older adults' mental health and physical frailty have been a frequent research focus, but few studies have investigated the relationship between them. OBJECTIVES: To investigate the association between mental health and physical frailty in community-dwelling older Japanese people. DESIGN: Cross-sectional study from the Itoshima Frail Study. SETTING: Itoshima City, Fukuoka, Japan. PARTICIPANTS: A total of 919 community-dwelling older individuals aged 65-75 years. MEASUREMENTS: Physical frailty was measured based on five criteria proposed by the Fried scale, and the subjects were classified into three groups: robust, pre-frailty, and frailty. Psychological distress was used to assess the subjects' mental health, with the Kessler 6-Item Psychological Distress Scale (K6) score; the subjects were divided into three groups based on their K6 score: 0-1, 2-4, and >=5. Psychological distress was defined by K6 score >=5. Ordinal logistic regression was used to estimate the odds ratios (OR) and 95 confidence intervals (CIs) between the psychological distress and physical frailty status.
