RÉSUMÉ
This study was conducted to examine the relationship between urbanization and risk factors of noncommunicable diseases [NCDs] according to the World Health Organization stepwise approach to surveillance of NCDs. This study is part of a NCD risk factor surveillance of 10 069 individuals in all provinces of the Islamic Republic of Iran, aged over 20 years, during 2011. By utilizing 2011 census data, urbanization levels were determined in all provinces and logistics regression was used to examine the relationship between urbanization and risk factors. Among males, urbanization had a positive correlation with low physical activity [OR=1.7; 95% CI: 1.42-2.09], low fruit and vegetable consumption [OR=1.8; 95% CI: 1.09-2.96], and high BMI [OR=1.4; 95% CI: 1.20-1.70]. Among females there was a positive and significant correlation with low physical activity [OR=1.2; 95% CI: 1.08-1.49], low fruit and vegetable consumption [OR=1.22; 95% CI: 0.78-1.91] and high BMI [OR=1.3; 95% CI: 1.14-1.53]. Thus, urbanization has a significant correlation with increases in NCD factors in the Islamic Republic of Iran
