RESUMO
BACKGROUND: Rehabilitation tailored to older adults' needs might improve their functional performance and quality of life, as well as increase social participation. The aim of the study was to evaluate the use of medical rehabilitation services among older Poles in relation to socio-economic and health-related determinants. MATERIALS AND METHODS: Data regarding medical rehabilitation were obtained from the nationwide, multidisciplinary PolSenior project (2007-2012) conducted on representative sample of 4813 respondents (48.3% women) aged 65+ years. Socio-economic status, physical functioning, falls, chronic pain, and formal disability occurrence, as well as self-rated health were accounted for. RESULTS: One in six respondents (18.9% women vs. 15.8% men, p < 0.005) underwent medical rehabilitation during 12 months prior to the survey. Respondents mostly received electrotherapy or light radiation therapy (61.3%). Multivariate logistic regression analysis revealed that women aged 80+ years and men aged 90+ years had a significantly lower chance of using rehabilitation services compared to the youngest study participants (65-69 y.o.). City dwellers used rehabilitation services nearly twice as frequently as rural dwellers. Respondents with university education level were most likely to take part in these services. Dependence in IADL decreased participation in medical rehabilitation, while formal disability and chronic pain promoted utilization of rehabilitation services. CONCLUSIONS: Younger age, city dwelling, higher education, functional independence, formal disability certificate, and chronic pain increased participation in medical rehabilitation. Such results of the study should be considered in planning actions towards reducing health inequalities at the national level and promoting health and well-being among older adults.
RESUMO
BACKGROUND: Immunosenescence is related to the deterioration of many immune functions, which may be manifested in increased susceptibility to infection, cancer, and autoimmunity. Lifestyle factors, such as diet or physical activity, may influence the senescence of the immune system. It is widely accepted that moderate physical activity may cause beneficial effects for physical and psychological health as well as for the immune system activity in aged people. METHODS: Thirty elderly women aged 62 to 86 were subjected to a two-years authorized physical activity program. Peripheral blood lymphocytes distribution and the production of cytokines involved in the immune response development and regulation (IL-2, IL-4 and IFN-gamma) were investigated. The same parameters were evaluated in two control groups of women: a sedentary group of 12 elderly women selected for the second round of the physical activity program and in a group of 20 sedentary young women. Flow cytometry methods were used for the examination of surface markers on peripheral blood lymphocytes and intracellular cytokines expression. RESULTS: The distribution of the main lymphocytes subpopulations in the peripheral blood of elderly women did not show changes after long-term moderate physical training. The percentage of lymphocytes expressing intracellular IL-2 was higher in the group of women attending 2-years physical activity program than in the control group of elderly sedentary women, and it was similar to the value estimated in the group of young sedentary women. There was no difference in the intracellular expression of IL-4 and IFN-gamma between the active and elderly sedentary women. CONCLUSIONS: Our results suggest that moderate, long-term physical activity in elderly women may increase the production of IL-2, an important regulator of the immune response. This may help ameliorate immunosenescence in these women.
