Abstract :
Trends in cholesterol level of different populations have been investigated in several studies. This study is conducted to determine the trend of cholesterol level of Iranian adults from 1990 to 2007. Data on cholesterol measurements of four national health surveys that have been carried out in Iran used in this study. Cholesterol level of 12728 adults aged 25-64 were measured in 1990-1 survey. Also in 1999, 2005, and 2007 surveys, blood cholesterol level of 18398, 52344 and 19630 have been sampled, respectively. The median of cholesterol were modeled with age for men and women separately for the four surveys using fractional polynomials. Then, trends in the median of cholesterol across these four surveys were studied. The analysis of cholesterol data over four national health surveys showed that the change in malesʹ cholesterol level had a decreasing trend. This decreasing trend was more pronounced in ages younger than 45 years. However, the medians of cholesterol of females during 16 years of four national surveys had a varying trend. It was decreasing in ages younger than 45; but increasing in ages over 45 years. The median of the cholesterol level of males and females in 2005 survey was on average about 10 mg/dl higher in comparison with the other surveys. Our findings showed that the pattern of trend in cholesterol level of Iranian men and women adults have a considerable difference with those of the other developing and developed countries.
