[Changes in the cardiovascular risk profile of the population of the Czech Republic--MONICA 1992].
BACKGROUND
The cardiovascular risk profile of the population in the Czech Republic is unfavourable, the mortality of the population from cardiovascular diseases is among the highest in the world. The objective of the present work was to compare the prevalence of the most serious risk factors in 1988 and 1992 and to find out whether the change of the political and economic system in 1989 had an impact on the risk profile of the population. Within the framework of the international WHO project MONICA independent 1% random population samples, age bracket 25-64 years, were examined in six districts of the Czech Republic.


RESULTS
In 1988 1,357 men (response rate 85.5%) and 1,412 women (88.4%) were examined; in 1992 1,139 men (71.2%) and 1,214 women (75.0%) attended the examination. The prevalence of smokers (regular consumption of more than 1 cigarette per day) did not differ significantly in men: 41.8% in 1988, 40.3% in 1992 nor in women: 25.3%-24.1%. Also the prevalence of elevated blood pressure levels (BPs > 21.3 and/or BPd > 12.7 kPa) did not reveal a significant difference neither in men: 19.1%-20.4% nor in women 14.0%-15.0%. The prevalence of hypercholesterolaemia (total cholesterol > 6.5 mmol/l) was in 1992 significantly lower than in 1988--in men by 9% (39.6%-30.6%, p < 0.001) and in women by 6.3% (36.3%-30.0%, p < 0.001). Also in the prevalence of obesity (BMI men > 30, women > 29) a significant drop was recorded in men by 5.2% (23.8%-18.6%, p < 0.01) in women by 5.1% (33.3%-28.2%, p < 0.01).


CONCLUSIONS
The probable reason for this partial improvement of the risk profile in 1992, as compared with data in 1988, are dietary changes which may be the result of the introduced market economy and global transformation of society after the political change in 1989.
