Objective: Frailty is defined as an aging-associated syndrome characterized progress loss of physiologic reserve and function in multiple organ systems. Frailty is highly prevalent with increasing of the elderly population. Frailty is expected to be an important public health problem because the socio-economic burden for elderly population has risen exponentially. Korea is one of the rapidly aging countries in the world. Especially, Rapid aging of the farmer population is one of important social issues in Korea. Therefore, frailty may be a more important problem in farm population. Understanding the characteristics of frailty of farmers should help to design medical and public health programs for aging populations. The purpose of this study was to investigate the relationship between frailty and socio-demographic, functional, and behavior factor in Korean farmers.
Method: Cardiovascular health study (CHS) frailty index by Fried et al. with five domains is the most extensively tested instrument: unintentional weight loss, exhaustion, low physical activity, slow gait speed, and weakness of handgrip strength. In this criteria, a score of 0 was considered as robust, 1 to 2 as prefrail, and 3 to 5 as frail. Recruited subjects were completed anthropomorphic measurements and structured questionnaires such as Korean version of MMSE in the Korean version of CERAD Assessment Packet (MMSE-KC), International Physical Activity Questionnare (IPAQ), Center for Epidemiologic Studies Depression (CES-D), Korean version of Activities of daily living (K-ADL), and Pittsburgh Sleep Quality Index (PSQI).
Results: A total of 539 farmers were enrolled. Subjects were excluded for the following reasons: a preexisting neurological or psychiatric disease or disease that was expected affect gait speed or answering questionnaire, such as stroke (n=2), dementia (n=1), depression (n=4), cancer (n=2), arthritis (n=18), fracture (n=7) and COPD (n=1). Finally, 504 farmers (255 males, mean age 60 years) included participants in this study. In univariate logistic regression analysis, prefrail was significantly associated with orchards farming (OR=2.019, P=0.014) and CES-D (16≤; OR=1.166, P=0.002), while frail was significantly associated with dependent ADL (7<; OR=11.156, P<0.008) and sedentary behavior (540min/day≤, OR=46.095, P<0.001). In multivariable logistic regression analysis, prefrail was related with CES-D (16≤; OR=2.843, P<0.001), while frailty was significantly associated with dependent ADL (OR=7.8, P<0.046) and sedentary behavior (OR=15.584, P<0.001).
Conclusion: This study purposed to identify the association between prefrail/frail and related factors in farmers. Subjects with depressive mood had a 2.843 times higher risk of experiencing prefrail compared to those with normal mood. Frailty is more prevalent among Korean farmers who exhibit dependent ADL and a great amount of time spent sitting.
