  Background and Aim: Physical inactivity is one of the 10 leading causes of mortality and disability. This study aimed to investigate the effect of e-learning on physical activity and body mass index (BMI) of female-employees.

Materials and Methods: In this semi-experimental interventional study, 120 female-employees of Tehran University of Medical Sciences were selected randomly and assigned to a case or control group. Data were collected using a demographic and an international physical activity questionnaire. Pre-test and post-test questionnaires were completed by the case and control subjects prior to, and 2 months after the final phase of, the intervention. The intervention included virtual education through short message service (SMS), email messages or messages via intanet, and educational films for a period of 16 weeks. SPSS-17 was used to analyze the data, the statistical tests being Chi-square, independent and paired-t, and Fisher's exact tests.

  Results: The mean age of the participants was 41 and 39 years in the case and control group, respectively. Most of them held a bachelor's degree and were married with 1 or 2 children. After the intervention, the mean score of physical activity in the intervention group increased significantly as compared with the control value (p<0.001). However, the intervention did not produce any change in the mean BMI of the case in comparison with the control group (p=0.119), although it brought about a statistically significant reduction in the initial BMI (p<0.001).

  Conclusion: Web-based education, SMS and multi-media messages can increase physical activity in female-employees and might prevent illnesses caused by physical inativity.
