[Association between fear of falling and activities of daily living among community-dwelling Japanese older adults].

Objectives　This study aimed to explore the association of difficulties in activities of daily living (ADL) (activities related to bending, spine extension, standing endurance, and walking) with fear of falling among community-dwelling older adults.Methods　We recruited 642 older adults (men, n=267; women, n=375) aged 65 years and over. The mean age was 72.2±5.1 years. Fear of falling, falls in the previous year, pain (low back pain or knee pain), comorbidity, and cataracts were assessed using a self-administered questionnaire. ADL difficulties were assessed individually, such as activities related to bending (getting in or out the car, picking up a lightweight object, putting on socks or stockings, and lifting a 5 kg object from the floor), spine extension (reaching an object above your head), standing endurance (standing on your feet for 2 h), and walking (walking 100 m on a level surface, climbing 10 steps without stopping, and walking down 10 steps). The independent association between fear of falling and each ADL difficulties was assessed using logistic regression analysis.Results　Participants with fear of falling, compared with those without fear of falling, had an older age (74.8 and 71.6 in men, 73.3 and 71.0 in women, respectively; P<0.01), more falls in the previous year (21% and 9% in men, 28% and 11% in women, respectively; P<0.05), pain (80% and 61% in men, 82% and 64% in women, respectively; P<0.01), and comorbidity (23% and 15% in women, respectively; P<0.05). Multivariate logistic regression analysis identified each ADL difficulties except walking 100 m on a level surface as being independently associated with fear of falling after adjusting for age, body mass index, sex, falls in the previous year, pain, and comorbidity.Conclusion　ADL difficulties, such as activities related to bending, spine extension, standing endurance, and walking, except for walking 100 m on a level surface, were associated with fear of falling.
