Effects of Knowledge Program on Changing Health Behavior of Village Health Volunteers with Obesity

Abstract

This quasi-experimental research aimed to compare body mass index (BMI), knowledge and behaviors on body-weight control in 40 village health volunteers. The one group pretest and posttest design was used for this study. The participants were 40 village health volunteers, who had BMI and waist circumferences higher than standards. The knowledge program for changing health behavior was used as an intervention tool. In addition, a questionnaire related to knowledge and behaviors linked to exercise, food consumption and emotional expression was employed for collecting data. The questionnaire had its reliability = 0.722 assessed by Cronbach's alpha method. Data were analyzed by percentage, mean, standard deviation and inferential statistics in terms of independent t-test.
The results indicated that after the intervention, the participants had their BMI and mean of knowledge and behaviors higher than before the intervention significantly (p<0.05).
