Physical Activity, Functional Capacity and Quality of Life in Older Patients With Chronic Comorbidities

Globally, the elderly population is increasing, along with a significant rise in the prevalence of chronic conditions such as obesity, hypertension (HT) and type 2 diabetes (T2D). The World Health Organization (WHO) reported in 2021 that over 2 billion adults were overweight, with more than 800 million classified as obese. At the same time, HT affected 1.28 billion adults globally, and the incidence of T2D surged from 108 million in 1980 to 537 million in 2021. Focusing on the older population, recent studies show that around 50% of older adults are affected by obesity, approximately 52.9% suffer from HT, and about 27.5% have T2D. The high prevalence of chronic diseases among older adults poses a significant health challenge and strains healthcare systems globally. This challenge is driven by increased life expectancy and the rapid aging of the population, which together lead to a larger elderly population and, consequently, a higher incidence of chronic diseases. Obesity, T2D, and HT can lead to complications in the cardiovascular and musculoskeletal systems, which in turn are likely to negatively affect PA, functional capacity, and QoL. For instance, obesity can increase the load on joints due to excessive weight, thereby restricting mobility, while T2D may adversely affect walking capacity through peripheral neuropathy and vascular complications. Hypertension could exacerbate symptoms during PA by increasing the cardiovascular load. In managing chronic diseases such as obesity, HT, and T2D, medications play a vital role in controlling these conditions and preventing complications. Nevertheless, even with this treatment, patients may continue to experience declines in functional capacity, PA, and QoL. The impact of chronic diseases such as obesity, HT, and T2D on PA, functional capacity, and QoL in older adults remains unclear in the literature. Although early detection and prevention of these conditions are important, the specific effects on these health aspects are not well-defined. Research indicates that while these conditions can influence health, their impact varies among individuals, and effective management may mitigate some adverse effects. Further research is needed to clarify how chronic diseases such as obesity, HT, and T2D affect PA, functional capacity, and QoL in the older population, as there remains a significant gap in empirical data regarding these effects. Therefore, the aim of our study is to compare PA, functional capacity, and QoL between patients with obesity, HT, T2D, and healthy controls, and to elucidate the differing impacts of these chronic conditions on these parameters. The physical activity level will be evaluated using the short form of the International Physical Activity Questionnaire (IPAQ), the functional capacity will be evaluated using the 6-minute walk test, and the quality of life will be evaluated using the SF-36 Quality of Life Scale. At the end of the study, physical activity, functional capacity and quality of life will be compared between older patients with chronic comorbidities and healthy peers.
