Awareness of the Prevention of Work-Related Diseases among Farmers - Based on Qualitative Research Methods / 農村醫學 地域保健

Objective@#This study was conducted to investigate the awareness of work-related disease prevention of farmers.Method: As a research method, a qualitative focus group interview was conducted in 18 participants. @*Results@#Prevention and management services for work-related diseases of farmers mostly are based on research from other fields and so are not highly effective because their content is not relevant to agricultural work. It has been suggested that such program designers be required to have some appropriate related knowledge, and that incentives and a certification system for participation in such education be established. To analyze work-related diseases of farmers, fields of prevention, diagnosis, treatment, and rehabilitation should be created. They demanded the designation of hospitals and the actualization of compensation for farmers' safety insurance. The work-related diseases to address were include musculoskeletal diseases, pesticide poisoning-related diseases (cardiovascular disease, respiratory disease), psychiatric diseases such as depression, and allergic diseases. However, this must have been the result of the harmful factors they felt during agricultural work. And for farmer patients diagnosed with work-related diseases, it was said to strengthen farmer safety insurance. @*Conclusion@#In order to increase the safely and health effects of agricultural work, it is necessary to prevent and manage work-related diseases of farmers. Projects should be developed in consideration of cultural and economic barriers of farmers and the characteristics of the work.

Associations between Frailty in Older Adults and Malnutrition in Rural Areas: 2019 Updated Version of the Asian Working Group for Sarcopenia

Purpose@#The purpose of this study was to evaluate the prevalence of frailty among an older adult population living in rural communities and to determine if frailty is associated with nutritional status after adjusting for sarcopenia and depression. @*Materials and Methods@#This research used baseline data from the Namgaram-2 study. Frailty was evaluated using the Kaigo-Yobo checklist in an older Korean population. The nutritional statuses of older people were measured using the Korean version of the mini nutritional assessment (MNA). The recent criteria of the Asian Working Group for Sarcopenia were applied for diagnosis of sarcopenia, and depression was assessed using the Geriatric Depression Scale-Short Form. @*Results@#The prevalence of frailty was 18.8% (male: 9.6%; female: 23.4%) and was significantly higher in individuals in their 80s [male, 35.3% (p<0.001); female, 42.3% (p<0.001)], those of poor economic status [male, 18.2% (p=0.012); female, 34.9% (p<0.001)], those with hypertension [female, 27.7% (p=0.008)], those with sarcopenia [male, 34.1% (p<0.001); female, 37.2% (p<0.001)], those with depression [male, 46.4% (p<0.001); female, 51.7% (p<0.001)], and those at high risk of malnutrition [male, 44.4% (p<0.001); female, 51.7% (p<0.001)]. After adjusting for demographic variables, including hypertension, diabetes, sarcopenia and depression, frailty was significantly associated with nutritional status [male: odds ratio (OR)=6.73, 95% confidence interval (CI), 1.84–24.65; female: OR=4.83, 95% CI, 2.88–8.11]. @*Conclusion@#For older adults, MNA is a suitable tool of use in assessing both nutritional status and frailty. Moreover, the nutritional status of older adults appears to be associated with frailty, even after corrections for physical and psychological function.

Barriers related to Walking Activity according to the Age Group of Rural residents / 農村醫學 地域保健

Objective@#This study aimed to report the relationship between walking activity and perceived physical activity barriers after classifying the age group(≤64, 65-74, ≥75). @*Methods@#The subjects were conducted on 1500 residents of two areas, and the walking activity was defined as five or more times a week, 10 minutes or more at a time, and 30 minutes or more per day. Perceived physical activity barriers were lack of time, lack of social support, lack of energy, lack of willpower, and fear of falling. @*Results@#In the group under 64 year, the lack of time (exp(B)=0.819, p=0.002) and the lack of willpower (exp(B)=0.656, p<0.001) were significantly associated. In the 65-74 year old group, the lack of willpower (exp(B)=0.714, p<0.001) and fear of falling (exp(B)=0.787, p=0.003) were a significant association. In the group aged 75 years and over, lack ofwill power (exp(B)=0.734, p<0.001) and fear of falling (exp(B)=0.807, p=0.003) were significantly associated. @*Conclusion@#In order to solve the lack of willpower and lack of time, a walking activity should be performed together at a certain time in the village, and the elderly in the late ages should reduce the fear of falling by performing a fall prevention exercise in parallel.

Validation of the Western Ontario and McMaster Universities Arthritis Index Short Form (WOMAC-SF) and Its Relevance to Disability and Frailty

PURPOSE: This study aimed to evaluate the validity of the Western Ontario and McMaster Universities Arthritis Index Short Form (WOMAC-SF) for the assessment of musculoskeletal disorders. We evaluated whether WOMAC-SF correlated with the World Health Organization Disability Assessment Schedule 12 (WHODAS-12) and Kaigo-Yobo questionnaires for assessing health-outcomes in Korea.MATERIALS AND METHODS: This cross-sectional study used data from the Namgaram-2 cohort. WOMAC, WOMAC-SF, WHODAS-12, and Kaigo-Yobo questionnaires were administered to patients with musculoskeletal disorders, including radiology-confirmed knee osteoarthritis (RKOA), sarcopenia, and osteoporosis. The relationships among WOMAC-SF, WHODAS-12, and Kaigo-Yobo scores were analyzed by stepwise multiple regression analysis.RESULTS: WOMAC-SF was associated with the WOMAC questionnaire. The results of confirmatory factor analysis for the hypothesized model with two latent factors, pain and function, provided satisfactory fit indices. WOMAC-SF pain and function were associated with RKOA. Kaigo-Yobo was associated with WOMAC-SF pain (B=0.140, p=0.001) and WOMAC-SF function (B=0.042, p=0.004). WHODAS-12 was associated with WOMAC-SF pain (B=0.679, p=0.003) and WOMAC-SF function (B=0.804, p<0.001).CONCLUSION: WOMAC-SF was validated for the evaluation of low extremity musculoskeletal disorders and health-related quality of life in a community-based population. Furthermore, we confirmed that WOMAC-SF were reflective of disability and frailty, which affect health outcomes.

The Association of Perceived Neighborhood Walkability and Environmental Pollution With Frailty Among Community-dwelling Older Adults in Korean Rural Areas: A Cross-sectional Study / 예방의학회지

OBJECTIVES@#The aim of this study was to evaluate the associations of frailty with perceived neighborhood walkability and environmental pollution among community-dwelling older adults in rural areas.@*METHODS@#The participants were 808 community-dwelling men and women aged 65 years and older in 2 rural towns. Comprehensive information, including demographics, socioeconomic status, grip strength, polypharmacy, perceived neighborhood environment (specifically, walkability and environmental pollution), and frailty, was collected from participants using face-to-face interviews conducted between June and August 2018. Perceived neighborhood walkability was measured using 20 items that were selected and revised from the Neighborhood Environment Walkability Scale, the Neighborhood Walkability Checklist from the National Heart Foundation of Australia, and the Physical Activity Neighborhood Environment Survey. The Kaigo-Yobo Checklist was used to assess participants’ frailty.@*RESULTS@#The overall prevalence of frailty in this community-dwelling population was 35.5%. Sex, age, cohabitation status, educational attainment, employment status, grip strength, and polypharmacy were significantly associated with frailty. In the logistic regression analysis, frailty was associated with low perceived neighborhood walkability (adjusted odds ratio [aOR], 0.881; 95% confidence interval [CI], 0.833 to 0.932; p<0.001) and severe perceived neighborhood environmental pollution (aOR, 1.052; 95% CI, 1.017 to 1.087; p=0.003) after adjusting for sex, age, cohabitation status, educational attainment, employment status, monthly income, grip strength, and polypharmacy.@*CONCLUSIONS@#More studies are warranted to establish causal relationships between walkability and environmental pollution and frailty.
