National Survey of Non-Communicable Diseases Risk Factors in 2016 (STEPs)
 

What Is STEPs


In the 2016 Stepwise Approach to Non-Communicable Risk Factors Surveillance (STEPs) survey in Iran, the mean and prevalence of non-communicable risk factors have been estimated in province level. However, the mean and prevalence of risk factors of the non-communicable diseases are not equally distributed among districts in each province. The district level data can be considered to determine priority setting and public health policy. So, in the 429 districts of Iran, non-communicable risk factors were estimated by small area estimation using bayesian spatial mixed-effect regression model. The input data for small area estimation have been achieved from the STEPs 2016 survey in Iran and age-standardized and all-ages estimates were obtained by sex in each district.

 

Objectives of the project


    1. To determine the prevalence of major preventable risk factors of non-communicable diseases in Iran (including: smoking, poor nutrition, low physical activity, high blood pressure, overweight and obesity, high blood glucose, and high blood lipids) by age and sex groups
    2. To determine the trend of major preventable risk factors of non-communicable diseases in Iran by age and sex groups based on data generated from the annual studies

     

     

  • Samples under study: 31000 subjects
