Purpose: Increased life expectancy leads to an increase in the elderly population. However, with an increase in the age, the number of chronic diseases and cognitive disorders also increases. Since the social, cultural, environmental, lifestyle and health-related behavior is specific to each nation, the present study aimed at investigating the relationship between socio-economic status, health, physical fitness, and cognitive function in older adults with functional performance in Iran.Methods: It is a cross-sectional study involving 42 older adults (20 women, 22 men) through a survey questionnaire and accessible sampling method. The age range of the study participants was 60 to 91 years. The questionnaire was used by the examiner to collect information on the age, height and weight, history of diseases, health status, physical fitness, and socio-economic status, for assessing the functional performance of older adults. The three performed tests included Sit-toStand test to examine the strength and lower extremity function, the Timed Up and Go (TUG) test to measure the speed and balance while walking and the Purdue Pegboard Test (PPT) for measuring the hand function. A step-wise regression model analysis was applied by using SPSS (version 19). Results:In sit-to-stand test, the test of significance of regression coefficients was profound in case of dependent variables (marital status (P=0.003) and overweight (P=0.014)). In TUG test, the dependent variables, age (P=0.002), marital status (P=0.081), and cognitive function (P=0.048) were influential on the TUG performance. In PPT, the independent variables, age (P=0.041), gender (P=0.012), marital status (P=0.058), and cognitive function (P=0.001), had a significant effect on the hand function. Conclusion:Age-related changes, cognitive functions, and socioeconomic status were the most important factors affecting the functional performance of the elderly. Weight and gender also affected some aspects of functional performance. The author further recommends controlling and preventing loss of cognitive function and improving the social status and age-related changes in the older Iranian adults.

Purpose: Due to unhealthy lifestyles, there has been an increase in the prevalence of coronary artery disease (CAD) and a reduction in its age of onset. Given the high cost of diagnosis and treatment of CAD, there is an urgent need to teach people strategies helpful in changing their lifestyles as this can help reduce the risk factors of the disease. Therefore, the goal of the present study was to examine the relationship between physical activity and risk factors of CAD in patients suspected with thid disese in Tehran City. Methods:In this cross-sectional study, a total of 92 patients with suspicion of CAD were examined. Interviews, patient medical history, and angiography reports were used to collect data. In addition, the International Physical Activity Questionnaires (IPAQ) was used to determine the level of physical activity of the patients. Results:The study results indicated 6% increase in the chance of having CAD for each oneyear increase in age. Patients who smoked cigarettes were about four times more likely to have coronary atherosclerosis than non-smokers. Among all participants, 34.7% had low physical activity, 43.47% had moderate physical activity, and 21.73% had high physical activity. A reverse and significant relationship was seen between the level of physical activity and number of narrowed coronary arteries. There were direct and significant relationships between blood glucose, cholestrol , and LDL with the number of involved coronary arteries. Conclusion:Among the effective factors for heart diseases, older age and smoking had the highest correlations with the chance of catching CAD. Based on the study results, changing lifestyle, including diet and more physical activity is related to the number of involved coronary arteries.
