distributions of high-sensitivity c-reactive protein, total cholesterol-hdl ratio and 10-year cardiovascular risk: national population-based study

the present study aimed to evaluate the distributions of high-sensitivity c-reactive protein, tc-hdl ratio and 10-year risk of cardiovascular diseases among iranian adult population. we conducted a cross-sectional study on a total of 2125 adults aged 25 to 65. data of the third national surveillance of risk factors of non-communicable diseases (surfncd-2007) was used. anthropometric indices, blood pressure and biochemical measurements had been obtained. ten-year risk of cardiovascular events was also calculated using different models. median (interquartile range) and geometric means (95% ci) of hs-crp were 5.1(3.9) and 4.1(4.38-4.85), respectively. mean tc-hdl ratio±(sd) was 5.94±2.84 in men and 5.37±1.97 in women ( p <0.001). in spite of risk scores (frs and score), no significant gender and age-related differences were observed in hs-crp levels. exclusion of crp levels≥10 did not change the results. the proportion of high-risk categories using score and frs models were 3.6 % and 8.8 %, respectively. in comparison with other published data, greater means and median values of high-sensitivity c-reactive protein were observed. higher tc-hdl ratio and cardiovascular risk in men than in women were also demonstrated. the issue of screening for cardiovascular diseases has yet to be addressed due to considerable prevalence of elevated crp and increased risk of cardiovascular events among various subgroups.
