The aim of this study to assess the level of physical activity among diabetic patients in Kurdistan and determine the association between levels of physical activity and certain variables of socio-demographic and clinical data. Methods: This cross-sectional study was conducted on 444 diabetes patients in the Kurdistan region of Iraq. The data was collected from 20th June to 10th September 2018 through interviews by using a questionnaire checklist. The data was analyzed by using the statistical package for the social sciences program. Results: Nearly half of the participants (49.1%) were middle-aged (36-55 years).
