    【Objective】This study aimed to examine the correlates of fall among workers in the retailing industry.

    【Methods】This study targeted the workers of 3 shops and 3 delivery centers of the Consumer Co-operative Kobe, a grocery-retailing company. Among them, 397 workers responded to the questionnaire and agreed to the use of their health data which the company had. The questionnaire inquired about fall experience during 1 year in occupational and non-occupational settings, Demura's fall risk assessment chart (physical function, disease and physical symptoms, environment, and behavior and character), and demographic factors (gender, age, exercise habit, and use of glass). From the health data, smoking habit, grip strength, body mass index, corrected visual acuity, blood pressure, urinary acid concentration, and diagnosis of diabetes were used.

    【Results】Among participants, 6.5% fell in occupational settings. Logistic regression analysis revealed that those who worked at delivery centers (adjusted odds ratio [AOR], 15.13; 95% confidence interval [CI], 3.12‒73.46; p=0.001) and those who fell in non-occupational settings (AOR, 3.11; 95% CI, 1.07‒9.07; p=0.038) were more likely to fall in occupational settings, and that those with higher grip strength (AOR, 0.34; 95% CI, 0.13‒0.87; p=0.024) were less likely to fall in such settings. Other factors were not significantly correlated with fall in occupational settings.

    【Conclusion】This study found that fall in non-occupational settings, working in delivery centers, and lower status of grip strength are correlated with fall in occupational settings among workers in a retailing company.

    【Objective】We aimed to clarify the mechanism of falls associated with cognitive decline by investigating the cognitive processes through which patients perceived and judged their own mobility.

    【Methods】We assessed 304 patients with an average age of 82 (range, 65-97) years who were hospitalized in a community-based integrated care ward after acute-phase treatment. Pre-hospitalized mobility was assessed according to information from the family. Actual mobility (Functional Independence Measure [FIM] transfer and gait), perceived mobility (physical functioning subscale on SF-8), and cognitive function (Mini-Mental State Examination [MMSE]) scores for each patient were evaluated upon admission and discharge. The presence or absence of falls was assessed three months after discharge. The participants were divided into three (high, medium, and low) or two (high and low) groups according to MMSE scores. We analyzed the cognitive processes involved in the patients’ perception and judgment of their mobility using structural equation modeling, and investigated whether a discrepancy between actual and perceived mobility affected the occurrence of falls after discharge using binomial logistic regression analysis.

    【Results】Structural equation modeling indicated that self-evaluated mobility was affected by actual mobility at the time of admission in the group with high MMSE scores, and was affected by pre-hospitalized mobility in the groups with medium and low MMSE scores. Binomial logistic regression results showed that a discrepancy between actual (at discharge) mobility and perceived (pre-hospitalized) mobility affected the occurrence of falls at three months after discharge in the group with low MMSE scores.

    【Conclusion】After acute-phase treatment, elderly patients with cognitive decline overestimated their mobility based on the mental representation of their pre-hospitalized mobility, and the inaccurate perception can lead to risky judgment and an increased risk of falls.
