The Trend of Changes in the Risk Factors of Coronory Heart Disease from 1980 to 2010 in Iran

[Background]Industrialization is the significant cause of death and inability in the most developed and ‎developing countries, and a greater part of nourishing inadequacies and infectious ‎diseases is attibuted to this outcome of modernity. The current study aimed at determining the status of the cardiovascular disease progression in Iran (as a developing country) by assessing the trend of risk factors such as blood pressure (PB), total cholesterol, and body mass index (BMI) from 1980 to 2010.[Methods]The current cross sectional study was conducted based on aggregate data extracted from the Gapminder Website. No sampling was done in the study. The research was conducted from 1980 to 2010. The bivariate Pearson correlation, independent samples t test, and message sequence charts were used to analyze data with SPSS version 16; α = 0.05 was considered the level of significance.[Results]The mean total cholesterol in females over 3 decades showed an increasing trend. The mean BMI increased within the study period. The mean BMI of males decreased from 1980 to 1997 and then, increased until 2008; while it remained constant in 2009 and 2010. The mean PB decreased in females aged above 31 years. The total cholesterol levels in males decreased from 1980 to 1990 and afterwards increased to 2010. The mean BMI of males increased in the same period.[Conclusions]By the improvement of lifestyle, healthy nutrition, purposive training, and increasing the knowledge about risk factors of chronic heart disease (CHD), these risk factors as well as the rate of CHD reduced in the studied population.
