Descriptive characteristics of the participants.

Background
The human body changes during life, but research on how sociodemographic characteristics and physical activity (PA) related to all aspects of body image are still unclear and there is conflict in the relevant results. This study aims to examine gender-specific body image perception and physical activity in relation to BMI and sociodemographic characteristics among health employees who worked in health and medical care centers.
Methods
The study was a population-based cross-sectional survey of 170 health employees (55 men and 115 women) in Binaloud, Iran. Participants completed a self-administered questionnaire, which consisted of a self-administered Multidimensional Body-Self Image Questionnaire (MBSRQ) and stages of change scales. The full version of Marcus-TTM based on the stages of physical activity changes was used based on 5 items related to regular physical activity behavior and intentions.
Results
There were no significant differences between men and women in total body image score, body area satisfaction, and attitude. Disease orientation (p = 0.02) and health orientation (p = 0.05) were the only significant differences between men and women. The number of children, level of education, BMI, and PA had a stronger influence on body image concerns and body dissatisfaction. PA and 7 of the 10 subclasses of MBSRQ (appearance evaluation, fitness evaluation, fitness orientation, health evaluation, health orientation, and illness orientation) showed a significant difference (P<0.05) between participants in the five TTM stages.
Conclusion
The ideal body image and body satisfaction may differ by the number of children, level of education, gender, BMI, and PA. Evidence from this study supports that participants’ stages of change affect their physical activity and body image perception. This result suggests a need for conducting work/home place intervention to promote adults’ body image perception and body area satisfaction based on the usage-specific stage under consideration.
