Globally, one in four adults does not meet the WHO-recommended level of physical activity. Insufficient physical activity is the fourth leading risk factor, contributing to 9% of global premature mortality. PA is effective in weight management, cardiorespiratory fitness, and increasing quality of life. However, there is lack of evidence on effectiveness on promoting physical activity in community level. The aim of the study is to test the effectiveness of Female Community Health Volunteers (FCHVs)-led community-based educational program on physical activity promotion in community level. This is an open label cluster-randomized controlled trial with 1:1 allocation where FCHVs will deliver a family-based education for the promotion of physical activity at community level in Nepal. The intervention package will be guided by Theory of planned behavior and will contain home-based interactive health education sessions focused on increasing PA in a household setting. FCHVs will use resource materials for health education. The mixed-effect linear regression model will determine the adjusted interaction between time and intervention. The results of this study will show the changes in the mean moderate to vigorous physical activity minutes per day due to time intervention interaction. The evidence generated from this study will help to provide new knowledge on the community-based promotion of Physical Activity and its effectiveness for policymakers and researchers. It will hopefully support the attainment of the national and global target of reducing insufficient physical activity.
