A Survey on the Effects of the Penderʹʹs Health Promotion Model on Prediction of the Employeesʹʹ Physical Activity

Aims: Most of the world population who is at work and production age does not have appropriate and regular physical activity for various reasons. Accordingly, the researchers tried to evaluate the effect of physical activity predictors of employees through the path analysis based on the Penderʹs Health Promotion Model (HPM). Methods and Materials: We conducted this study on 359 employees of the milk and milk powder production factories in Mashhad. A questionnaire consisted of items related to the structure of the Penderʹs Health Promotion Model (Perceived Benefits, Perceived Barriers, Prior Related Behavior, Perceived Self-Efficacy, Activity Related Affect, Personal Factors, Interpersonal Influences and Situational Influences) and the IPAQ standard questionnaire related to the physical activity were designed and applied in interviews as data collection instruments. Findings: One fourth of the employees had proper physical activity. Generally, structures of the Penderʹs Health Promotion Model predicted 34.8 % of the physical activity behavior variance. Regression analysis has shown that the predictability of Prior Related Behavior, Perceived Self-Efficacy, Personal Factors, Activity Related Affect and Interpersonal Influences are significant and Situational Influences are nearly significant. Prior Related Behavior (B = 0.45, P < 0.000) and Self-Efficacy (B = 0.17, P < 0.001) had the highest positive predictability in physical activity. Conclusions: The findings of the study revealed that HPM is efficient in identifying and predicting the physical activity behavior. This pattern can be used as a framework for planning and implementing educational interventions in order to improve the physical activity of the adult employees.
