Type D personality and quality of life among polish university students: a cross-sectional study.

Chronological aging was considered as age over 65 years. World Health Organization classification of old age; He/she classified the 65–74 age group as “young and old”, the 75–84 age group as “old”, and the 85 and over age group as “older old”. The increasingly aging population is at risk in many ways. The most important of these risks include loss of balance and falling. Falls are a major health problem that causes high mortality, disability and workforce losses. Approximately 45% of the older adults in society experience falls every year. Falls can cause injury, loss of physical independence, or death in this population. In order to reduce the risk of falling and develop healthy strategies, factors affecting falls need to be determined. The deterioration of the organism and its functions along with the aging process reduces the ability of older individuals to adapt to environmental factors. This loss of adaptation causes a decrease in balance ability and locomotor capacity in older adults. Decrease in muscle strength, joint mobility, proprioceptive sense and vision with aging causes postural imbalances. In older individuals, balance is essential to continue activities such as taking steps, going up and down stairs, sitting and standing up. Urinary incontinence (UI), one of the urinary system diseases, is defined as involuntary loss of urine and is a common health problem in older adults that not only affects the individual but also brings with it many social problems. In older adults, UI may cause depression, impaired walking function, balance problems, falls, worsening of functional status and social isolation, and may make older individuals even more dependent. Poor locomotor capacity and reduced mobility may be considered a risk factor for urinary incontinence. The rationale for examining psychometric properties specifically in this population stems from the intrinsic link between mobility and UI; the physiological pressure of urgency often leads to a “hurried gait” and unstable postural transitions during the rush to reach a bathroom, creating a unique functional demand that requires validated assessment. Functional status, locomotor capacity and balance are frequently affected in older adults with incontinence, and improvements in these are an important goal of rehabilitation. Studies have found a significant relationship between the ‘Timed up and go test (TUG)’ and the severity of urinary incontinence. It has been stated that mobility, balance and functional status are more affected in older adults with incontinence. The rationale for selecting the TUG, Modified Four-Square Step Test (mFSST), 30-Second Chair Stand Test (30s-CST), and 2MinWT as primary outcome measures lies in their clinical brevity and ability to assess distinct components of locomotor capacity. In patients with UI, the urgency to reach a bathroom necessitates rapid transitions from sitting to standing (30s-CST), dynamic balance during directional changes (mFSST and TUG), and functional endurance (2-Minute Walk Test (2MinWT)). Validating these specific tools is essential for providing clinicians with time-efficient assessment options that directly reflect the functional demands of this population. Measures of physical function are used in older adults to determine the effects of an intervention or to predict future events such as hospitalization or death. Walking is an important determinant of health in older adults. Impaired walking performance in older adults has been associated with poor mobility, worsening functional status, increased risk of hospitalization, and decreased survival rate. Likewise, walking speed is associated with decreased balance ability and increased risk of falling. Berg Balance Scale (BBS), 30 s chair sit-to-stand test (30s-CST) and 6 m walk test are widely used in the clinic, are frequently compared with other balance measurements and are considered the gold standard measures for concurrent validity. The 30s-CST is one of the most important functional assessment clinical tests because it measures lower limb strength and relates it to the most demanding activities of daily living. Lower extremity muscle weakness has been identified as a risk factor for falls, inability to perform lower extremity functional tasks such as walking, sitting-to-standing transfers, climbing stairs, and lower extremity dressing. It is associated with decreased walking speed, decreased balance ability, and increased risk of falls; it can predict health status, survival and hospital costs.
