Introduction: The prevalence of Non-communicable diseases (NCDs) has increased so it's becoming a global public health problem. This problem is also threatening in Sub-Sahara Africa (SSA) country including Ivory Coast. Ivory Coast is a country of 22.6 million people experiencing rapid economic development and social change. All development is typically associated with an increase in non-communicable disease (NCD) risk factors. Our study aimed to determine the prevalence and associated factors of the major risk factors of NCDs among the population of Cocody, Abobo and Yocoboué in the Ivory Coast. Methods: A descriptive and analytical cross-sectional study was conducted and involved 1146 adults of 19 to 60 years from general population in Cocody (urban), Abob (peri-urban) and Yocoboué (rural). The WHO STEPS risk factor survey has been changed a bit and was administered. it contains anthropometric and biochemical measures. Results: The prevalence of NCD risk factors was markedly different across the three sites particularly between urban (Cocody) and rural (Yocoboué) areas. The overall prevalence estimates of the risk factors were 15.2% for current smoking, 57.71% for harmful use of alcohol, 58.84% for low physical activity, 24.71% for sedentariness (sitting at least 7 h), 69.45% for skipping breakfast, 61% for having late dinner and 36% for snacking. Concerning biological risk factor we noticed 40.95% for Overweight/obesity, 52.96% for abdominal obesity, 14.61% for raised blood pressure, 23.37% for raised blood sugar and 18.51 low HDL-C.
