A laboratory study was conducted to evaluate if two different age groups(young vs. old) had differences in walking velocity and heel contact velocity and, furthermore, if these gait characteristics could adversely influence initial friction demand characteristics(i.e. RCOF) and the likelihood of slip-initiation. Twenty eight(14 younger and 14 older adults) participated in the study. While wearing a safety harness, all participants walked at their preferred gait speed for approximately 20 minutes on the linear walking track(1.5m× 20m) consisting of two floor-mounted forced plates. During subsequent 20 cameras, respectively. The results indicated that older adults walked slower(i.e., slower whole body center-of-mass velocity), exhibited lower heel contact velocity, and produced lower initial friction demand characteristics (i.e. RCOF) in comparison to younger adults. However, ANCOVA indicated that the diferences in heel contact velocity between the two age groups were due to the effects of walking velocity. The bivariate analysis further suggested that walking velocity was correlated to RCOF and heel contact velocity, while heel contact velocity was not found to be correlated to RCOF. In conclusion, could be a better indicator for predicting initial friction demand characteristics(i.e. RCOF) not hel contact velocity.

Purpose: The purpose of this study is to identify factors influencing activities-specific balance confidence in community-dwelling older adults. Methods: This is secondary analysis of data from an intervention study for improving cognitive function. The data were collected from March 2 to September 30, 2017 at a senior center. Data of 131 older adults were included for this secondary analysis, and were analyzed by using t-test, ANOVA, and multiple regression. Results: The mean score of activities-specific balance confidence is 65.08 out of a possible range of 0-100. The significant factors affecting activities-specific balance confidence among old adults include 'more than 85 years old', 'waist circumference', 'depressive symptoms', 'activity restriction due to fear of falling', and 'self-rated health' which explained 52.8% of the variance. Conclusion: The study results indicate that psychologic factors as well as physical condition should be considered for interventions to increase activities-specific balance confidence.

Purpose: This study aimed to determine the prevalence of dizziness in adults and to identify factors associated with dizziness. Methods: This cross-sectional study used secondary data from the Eighth Korea National Health and Nutrition Examination Survey. Participants included 10,265 older adults aged≥40 years. Data were analyzed using descriptive statistics, the chi-squared test, and multinomial logistic regression with the SPSS/WIN 27.0 program. Results: The prevalence of dizziness was 26.2%, with 20.9% reporting episodic dizziness and 5.3% reporting chronic dizziness. Compared to that noted in the control group participants without dizziness, the risk of episodic or chronic dizziness was higher in women and in participants with older age, low education level, low income level, high perceived stress level, depression, tinnitus, and occupational noise exposure. Moreover, the risk of chronic dizziness was higher among those with a body mass index of <25 kg/m², stroke, cardiovascular disease, or severe hearing loss. Conclusion: The study underscores the need to comprehensively identify risk factors associated with dizziness and to develop interventions to prevent and manage the occurrence and chronicity of dizziness in the general population.

This study aims to observe the effect of age friendliness of cities on life satisfaction and to suggest ways to improve quality of life of older people. The secondary data sets were used in this study, which were '2014 Survey of Living Conditions and Welfare Needs of Korean Older People.' It's a nationwide data collected by the Korean Institute of Health and Social Affairs. A multilevel analysis model was used to analyze the data because the level of age friendliness has a hierarchical data structure. Results showed as follows: First, life satisfaction of older adults is affected by the level of age-friendliness of cities in which they live. Second, on the personal level, older people showed low life satisfaction when they are more older and have more chronic diseases and more depressed. On the contrary, life satisfaction of older adults increased when they have higher education and income. Third, on the city level, older people showed higher life satisfaction when they live in high employment rate area and participation rate of lifelong education. Cautions should be placed when interpret the result because the variables that represent the characteristics of age friendless of cities were constituted arbitrary. Based on the results, suggestions for improving the city environment age-friendly and implications for social welfare practice were provided.

Purpose: This study aimed to investigate health behavior related to particulate matter (PM) in older adults and examine the factors affecting it. Methods: A cross-sectional survey design was used. Data were collected from 150 voluntary older adult participants from Songpa-gu in Seoul. The survey questions measured service perception and experience related to PM, risk perception related to PM, attitude toward risk of PM, and health behavior related to PM. Results: The average score for health behavior related to PM was 79.37, ranging from 51 to 115. There was a significant positive correlation between health behavior related to PM and risk perception related to PM (r=.58, p<.001) as well as between health behavior related to PM and attitude toward risk of PM (r=.70, p<.001). Multiple linear regression revealed that health behavior related to PM was predicted by levels of the existence of disease related to PM (β=.14, p=.019), service experience related to PM (β=.20, p=.021), risk perception related to PM (β=.20, p=.019), and attitude toward risk of PM (β=.44, p<.001). The model including these variables accounted for 47.0% of health behavior related to PM. Conclusion: Korean older adults have the low level of health behavior related to PM. The findings of this study emphasize that risk perception and attitude toward risk of PM should be evaluated, and the underlying diseases related to PM and their service experience should be considered in developing intervention to improve health behavior related to PM.

Purpose: This study was conducted to identify risk factors that influence the probability and severity of elder abuse in community-dwelling older adults. Methods: This study was a cross-sectional descriptive study. Self-report questionnaires were used to collect data from community-dwelling Koreans, 65 and older (N=416). Logistic regression, negative binomial regression and zero-inflated negative binomial regression model for abuse count data were utilized to determine risk factors for elder abuse. Results: The rate of older adults who experienced any one category of abuse was 32.5%. By zero-inflated negative binomial regression analysis, the experience of verbal-psychological abuse was associated with marital status and family support, while the experience of physical abuse was associated with self-esteem, perceived economic stress and family support. Family support was found to be a salient risk factor of probability of abuse in both verbal-psychological and physical abuse. Self-esteem was found to be a salient risk factor of probability and severity of abuse in physical abuse alone. Conclusion: The findings suggest that tailored prevention and intervention considering both types of elder abuse and target populations might be beneficial for preventative efficiency of elder abuse.

Purpose: The purpose of this study was to explore the relationships among pain, depression, health behaviors, and activities of daily living (ADL) in older adults after femur fracture surgery. Methods: This was a descriptive correlational study. Ninety seven outpatients aged 65 or older were selected, who agreed to participate and visited the four hospitals located in G providence. Numeric Rating Scale (NRS) for pain, a Short form Geriatric Depression Scale (SGDS) for depression, health behavior scale and Korean version of Bathel Index for ADL were used. Data were analyzed using t-test and ANOVA, Pearson's correlation and the hierarchical regression analysis in SPSS 18. Results: Pain and depression were positively correlated (r=.35, p<.001). Pain and health behaviors (r=-.30, p=.010), pain and ADL (r=-.21, p=.044), depression and health behaviors (r=-.51, p<.001), depression and ADL (r=-.29, p=.004) were negatively correlated. The variables affecting the ADL was intake of a painkiller or not (${\beta}$=-.32), age (${\beta}$=-.25), transitional period after discharge (${\beta}$=.23) and depression (${\beta}$=-.23). ADL was accounted for 33.4% in total by these four variables. Conclusion: Interventions for alleviating pain, and managing depression would be effective in enhancing ADL in older adults after femur fracture surgery.

Background: Participation is one of the major factors affecting the long-term success of population-based prostate cancer screening programs. The aim of this study was to explore strong factors linked to participation in prostate cancer screening among older Jordanian adults using the Health Belief Model (HBM). Materials and Methods: Data were obtained from Jordanian older adults, aged 40 years and over, who visited a comprehensive health care center within the Ministry of Health. A pilot test was conducted to investigate the internal consistency of the the Champion Health Belief Model Scale for prostate cancer screening and the clarity of survey questions. Sample characteristics and rates of participation in prostate cancer screening were examined using means and frequencies. Important factors associated with participation in prostate cancer screening were examined using bivariate correlation and multivariate logistic regression analysis. Results: About 13% of the respondents had adhered to prostate cancer screening guidelines over the previous decade. Four out of the seven HBM-driven factors (perceived susceptibility, benefits and barriers to PSA test, and health motivation) were statistically significant. Those with greater levels of susceptibility, benefits of PSA test and health motivation and lower levels of barriers to PSA testing were more likely to participate in prostate cancer screening. Family history, presence of urinary symptoms, age, and knowledge about prostate cancer significantly predicted the participation in prostate cancer screening. Conclusions: Health professionals should focus more on the four modifiable HBMrelated factors to encourage older adults to participate in prostate cancer screening. Intervention programs, which lower perceived barriers to PSA testing and increase susceptibility, benefits of PSA testing and health motivation, should be developed and implemented.

This study intended to understand the way loneliness and depression affect psychological and physical health of older adults, and conducted a structural equational modeling of a relationship among loneliness, depression and health status of older adults. A survey was conducted on 329 individuals who were utilizing senior welfare agencies located in Seoul and the surrounding cities. The study examined the effects of loneliness and depression on their health status as well as the role of depression in this process. The data analysis showed a good fit of the structural model and suggested an evidence of depression fully mediating the effect of loneliness on health status. This result indicated that the current focus of services on increasing quantity of social contact among older people may need a paradigm shift towards improving their subjective loneliness and quality of interpersonal relationships.

The purpose of this study was to investigate social networks, loneliness, and sleep quality related to health-related quality of life in older adults living alone. Data were collected from 111 community-dwelling elderly. The data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple linear regressions with IBM SPSS 26.0 program. In multiple regression analysis, physical component summary (PCS) was predicted by the level of education (β=.20, p=.020), social networks (β=.31, p=.012), and sleep quality (β=-.23, p=.011). The model including these variables accounted for 25.7% of the variance in the PCS. Mental component summary (MCS) was predicted by loneliness (β=-.37, p=.004). Loneliness accounted for 31.7% of the variance in the MCS. In order to enhance the health-related quality of life of the older adults living alone, the intervention program to resolve social isolation should be provided for them.
