Examination of the correlation between hand grip strength and muscle mass, balance, mobility, and daily life activities in elderly individuals living in nursing homes.

BACKGROUND: Aging is a process that includes progressive physiological changes. Grip strength is an important indicator of current health in the elderly. OBJECTIVE: The aim of the study was to examine the correlation between dominant-hand grip strength (HGS) and cognitive function, mid-upper arm circumference, muscle-bone mass, balance, mobility, and daily life activities in elderly individuals living in nursing homes and determine the effect rates of these factors on HGS. METHODS: Seventy-two elderly individuals aged over 65 who lived in a nursing home were included in the study. Dominant HGS and mid-upper forearm circumference were measured. Muscle and bone masses were measured with bioelectrical impedance analysis. Mid-upper arm circumference was measured using a non-elastic tape. HGS was measured using a hand dynamometer. Cognitive function was evaluated with the Standardized Mini-Mental Test (SMMT); mobility and balance were evaluated with the Timed Up and Go Test (TUGT) and Berg Balance Scale (BBS); the Katz Activities of Daily Living Scale (KATZ ADL) was used to evaluate daily life activities. RESULTS: There was a significant correlation between HGS and muscle and bone masses (p < 0.001). A significant correlation was found between HGS and TUGT, ADL (p = 0.001, p = 0.016). There was no significant correlation between HGS and BBS (p = 0.2). There was a correlation between HGS and SMMT at the statistical significance limit (p = 0.055). On HGS, the Body Mass Index had a 64.9% effect; the muscle mass had a 30.9% effect; the TUGT had a 27.7% effect. These parameters were found to explain 59.9% of the variance. CONCLUSION: As a global indicator of muscle strength, HGS can be used to predict age-related functional changes. Approaches to increase physical activity levels in elderly can be effective in reducing age-related negativities.

Comparison of Short Form-36 Health Survey and Nottingham Health Profile in moderate to severe patients with COPD.

OBJECTIVE: To compare the health-related quality of life (HRQoL) assessed by Short Form-36 Health Survey (SF-36) and Nottingham Health Profile (NHP) on the basis of lung function and exercise capacity parameters in patients with moderate to severe chronic obstructive pulmonary disease (COPD). METHODS AND MATERIALS: The investigation was a prospective, quality-of-life survey and cross-sectional study of 130 consecutive COPD patients. The NHP and SF-36 as generic HRQoL instruments, the Chronic Respiratory Disease questionnaire (CRQ) as a disease-specific HRQoL instrument and 6-minute walking test, severity of dyspnea, leg fatigue and lung function, were the measurements and instruments used in the study. RESULTS: It was determined that the subscales of both questionnaires were generally related with the FEV(1), walking distance, CRQ, severity of dyspnea and leg fatigue values (P<0.05). The much higher correlation coefficient was determined between these parameters and NHP compared with the SF-36. Only NHP was found to be correlated with the age, body mass index and smoking consumption (P<0.05). CONCLUSIONS: The stronger relation of NHP with the clinical and physical parameters of the patients compared with that of SF-36 may be associated with the increased sensitivity of NHP to the clinical state owing to the increasing respiratory symptoms of our old patients with moderate to severe obstruction and/or the more intelligible and easy-to-respond nature of NHP compared with SF-36.
