Background: The extension of the life span has led to an increase in the number of older people and an increase in the prevalence of disability in people over 60 years of age. The aim of this study was to assess the prevalence of ADL and IADL disability and to analyze its determinants among people aged 60 and older living in southeastern Poland. Methods: This cross-sectional study was carried out among a randomly selected, representative population of people aged 60 and older living in southeastern Poland. Disability was assessed using the Katz Index of Independence in Basic Activities of Daily Living and Instrumental Activities of Daily Living. Logistic regression models were used to identify the factors related to ADLs and IADLs. For the variables that were included in the above models, their clustered influence on the increase in the odds ratio for the occurrence of an ADL or IADL limitation was also examined. Results: The research results show that 35.75% of the participants reported at least one problem with IADLs. At least one problem with ADLs was reported by 17.13% of the participants. The most significant modifiable factors influencing the occurrence of disability were the presence of barriers in the participant’s environment, poor relations with relatives, a lack of social contacts, multimorbidity and pain. A multiple increase in the odds ratio of disability was found with the presence of pairs of analyzed factors. The highest odds ratio of at least one ADL limitation was observed for the combination of barriers in the participant’s environment with multimorbidity (OR 74.07). With regard to IADL disability, the highest odds ratio was observed for the combination of pain on the VAS scale ≥3 points with older age (OR 19.47). Conclusions: The study showed a high prevalence of ADL and IADL disability in older people living in southeastern Poland. It also indicated the extent to which modifiable factors influenced the occurrence of disability and the extent to which the risk of disability increased with the presence of pairs of factors, especially those that included environmental barriers in the participant’s environment.

Introduction. Low muscle strength is common and important in geriatric syndromes including frailty and sarcopenia. The epidemiology of grip strength of older people under long-term care facilities has been little explored.Purpose. The aim of this study was to assess handgrip strength of older women and men covered by institutional care and to analyse the associations between HGS and mobility, leg strength, flexibility, and postural balance.Materials and Methods. This is a cross-sectional study carried out at care homes in southeastern Poland. After considering the inclusion criteria, 209 older people aged 65 to 85 were included in the study. Sociodemographic data were collected, and tests of muscular strength, mobility, flexibility, and postural balance were carried out by the use of the stabilometric platform CQ Stab 2P.Results. The average handgrip strength in the study group amounted to 19.8 kg, including 14.8 kg in women and 25.9 kg in men. Low grip strength was found in 67.83% women and 52.13% men in institutional care. A negative correlation between handgrip strength (HGS) and the Timed Up and Go (TUG) test was demonstrated, both with and without cognitive task and strength of lower limbs. Gait speed and dynamic balance were positively correlated with HGS. A negative correlation was found between the total length of the centre of pressure (COP) path, the length of the COP path in the lateral-medial direction, and the sway area delimited by the COP and HGS for the dominant hand. Speaking of women, gait speed was most strongly associated with HGS, while among men, it was upper limb flexibility.Conclusion. Regardless of gender, HGS is associated with mobility, strength of the lower limbs, and dynamic balance. By means of simple tools, early diagnosis will facilitate the planning of appropriate interventions in order to prevent disability and mortality in long-term care facilities.

Demographic changes in Europe have resulted in anincreased demand for healthcare and social care for the elderly. The aim of this study was to analyze the factors related to disability in ADL and IADL among elderly inhabitants of rural areas of southeastern Poland. The study involved 426 subjects aged 71-80 years. To assess their activities of daily living, the Katz ADL Scale was used, and the Lawton IADL Scale was used to assess their instrumental activities in daily living. The subjects reported at least one problem with IADL (43.19%) more often than with ADL (36.85%). The strongest factors related to difficulties with ADL were assessment of satisfaction with life, using assistive devices, and having one's home suitably adapted. The strongest factors related to IADL were the assessment of satisfaction with life, education, using assistive devices and performing moderate physical exercise at a minimum of 150 minutes per week. Age, education, pain, falls, household not fully adapted for one's needs, using assistive devices, lack of satisfaction with life, and low assessment of quality of life had a significant impact on the prevalence of ADL and/or IADL disabilities in the elderly inhabitants of rural areas. Most of these factors can be subject to modification. They are also a complex of predictors that allow for identifying and supporting those elderly patients from rural areas who are the most vulnerable.

Introduction: Quality of life (QOL) is an important aspect of life, reflecting health and conditioning the well-being of older adults. Maintaining the QOL is essential in times of demographic changes which resulting longer life spans, and consequently an increased proportion of older adults in...

Background: The assessment of disability in a population is an important part of public health management. In this article, we examine the psychometric properties and validation of the Polish version of the 12-item World Health Organization Disability Assessment Schedule 2.0. (12-item WHODAS 2.0). Methods: A systematic random sample comprised 584 adult urban residents. The Polish version of the 12-item WHODAS 2.0 and the World Health Organization Quality of Life-BREF, Short Form (WHOQOL-BREF) questionnaire were used to assess disability and quality of life, respectively. Basic sociodemographic data and selected health-related data (e.g., pain and depressive moods) were also collected. Results: Good scale score reliability for the entire tool was confirmed in the study population (Cronbach’s α = 0.90; Composite reliability = 0.95). In confirmatory factor analysis (CFA), satisfactory values of the fit indices were obtained (comparative fit index, CFI = 0.999; Tucker-Lewis Index, TLI = 0.999; root mean square error of approximation, RMSEA = 0.004; standardized root mean square residual, SRMR = 0.043, p = 0.454). Good consistency was noted over time (correlation coefficient = 0.88). The tool was found to have an appropriate level of validity. Conclusions: We found that the 12-item WHODAS is short and easy to use, and it is suitable for use in the form of an interview during screening tests. This tool is appropriate for measuring the health status, functioning, and disability of an average population. It may be more relevant for studying populations with health problems. The 12-item WHODAS can be used to successfully obtain information about the general level of disability in a population.

BACKGROUND:The proportion of elderly people living in Poland has risen in recent years. With rising life expectancy, there is likely to be a concurrent increase in the incidence of chronic diseases and disabilities. Therefore, this study aimed to ana...
