1. Title : RELATION BETWEEN HEALTH LOCUS OF CONTROL WITH HEALTH-PROMOTING BEHAVIORS of PEOPLE OVER 15 YEARS OLD By: Teamur Aghamolaei, Amin Ghanbarnejad Reserch Center for Social determinants of Health Promotion, Hormozgan University of Medical Sciences, Bandar Abbas, Iran. 1

2. Introduction Julian B Rotter in 1954. locus of control refers to the extent to which individuals believe they can control events affecting them. 2

3. Introduction Individuals with a strong internal locus of control believe events in their life derive primarily from their own actions. People with a strong external locus of control tend to praise or blame external factors 3

4. Introduction Wallston et al. (Health Locus of Control) Internal Powerful Other Chance 4

5. Aim To Study relation between Health Locus of Control (HLC) with Health Promoting Behaviors (HPB) of people over 15 years old in Bandar Abbas, Iran. 5

6. Methods Population based study Population study: people over 15 years old Be able to answer the items Cluster sampling 6

7. Methods Sample Size: 753 To omit cluster sampling effect: +10% 38 cluster from different areas of the city In each cluster 22 individual Totally: 836 7

8. Data Collection Wallston scales Forms: A, B, C In This Study: Form A Form A: Internal Chance Powerful Other 8

9. Data Collection Form A including 18 items: Likert 1(strongly disagree) to 6 (Strongly Agree) Internal: Six items, 6-36 Chance: Six items, 6-36 Powerful Other, Six Items, 6-36 9

10. Data Collection Health Promoting Behaviors was assessed by Health Promoting Lifestyle Profile II This scale has 52 items: Likert: 1-5 Six subscales including: Social Support Spiritual Growth Health Responsibility Stress Management Nutrition Behaviors Physical Activity 10

11. Data Analysis SPSS 19 Software Repeated measure Design T-test Pearson Correlation Multiple Regression 11

12. Results From 836 subjects 687 answered all of items of scales (Response rate=82.8%) The mean age of subjects was 34.3 years (SD=12.1) ranging from 15 to 82. 49.8% male and 50.2% female 12

24. Discussion As the result showed there was direct correlation between age with internal health locus of control and powerful other. In Grotz et al. study in Germany there was direct correlation between age with powerful other and chance. In Kuwahara et al. study in Japan there was direct correlation between age with all subscales of HLC. 24

25. Discussion As the results showed Internal health locus of control and powerful other predict HPB. Studies have shown that people with Internal health locus of control, more intend to take behaviors that can prevent disease and promote their health. In Grotz et al. study, people with high scores in chance had less physical activity. In Norman et al. study, people with high scores in internal health locus of control had more physical activity and better nutritional behaviors. 25

26. Conclusion HLC of Studied people is more internal followed by powerful other and is less by chance. Internal health locus of control and powerful other predict HPB. To increase knowledge of people regarding determinants of health and empower of them in order to promote internal health locus of control and finally improve HPB is recommended. 26
