However, it is possible to reach it in a healthy way. Many chronic diseases are preventable, and their prevention and early management mean reduction of enormous human, social, and economic cost to the country. This is especially important for developing countries.7 In Healthy People 2010, regular physical activity is ranked as a leading health indicator, and has been shown

to have many health benefits for all age groups.8 According to the World Health Inhibitors,research,lifescience,medical Organization,9 physical activity is the single most useful thing that individuals can do to maintain their health, daily function and quality of life. The challenge of the GF109203X public health is to promote the awareness of physical activity and its implementation as an important aspect of a healthy lifestyle among older adults. Physical activity may also offer a useful alternative to drug management by reducing the need Inhibitors,research,lifescience,medical for medication in some conditions, such as hypertension and type 2 diabetes in elder people.2 The benefits for elder people include improved fitness and quality of life.10 Unfortunately, despite the extensive benefits of physical activity, the population of older people

is much less active than desired.8 Therefore, Inhibitors,research,lifescience,medical the need to understand physical activity behavior and implement effective intervention strategies is paramount. This study was designed to examine to predictors of physical activity intention and behavior in a sample of elderly men of nursing home residents using theory of planned behavior (TPB) and the self-efficacy

construct. Theory of Planned Behavior Theories can be used to plan these programs by providing a method of understanding why people are or are not following public health and medical advice. Existing theories can help pinpoint what you need to know before developing an intervention Inhibitors,research,lifescience,medical program and provide insight into how to shape program Inhibitors,research,lifescience,medical strategies to effectively reach people and organizations. They can also help identify what should be monitored, measured and or compared to during program evaluations.11 The TPB explains and predicts physical activity behavior effectively.12 The TPB suggests that the proximal determinant of a volitional behavior is one’s intention to engage in that behavior. Intentions are the motivational factors that influence a behavior.13 Subjective norm and attitude are suggested to exert their effects Rolziracetam upon a behavior through its influence on one’s intentions. Subjective norm assesses the social pressures on an individual to perform or not to perform a particular behavior. Attitude is an individual’s positive or negative evaluation of self-performance of a particular behavior. Attitude is further divided into affective and instrumental attitudes. Previous research has consistently identified the construct distinction of these two attitudinal components.14 Thus in this study, affective and instrumental attitudes were modeled as distinct constructs. Currently, there are few studies on the behavioral theories in elder men.
