RESUMEN
Background: Hypertension is the most common cardiovascular disease which substantially increases cardiovascular morbidity and mortality. Despite the broad availability of antihypertensive medication, control of hypertension is not satisfactory worldwide. Objective: The study aim was to assess longitudinal trends in blood pressure, prevalence, awareness, treatment, and control of hypertension in a representative population sample of the Czechia from 1985 to 2016/2017, focusing on sex differences. Methods: A total of 7,606 men and 8,050 women aged 25-64 years were screened for major CV risk factors in seven independent cross-sectional surveys run consistently in the same six country districts of the Czechia between 1985 and 2016/2017. The population samples were randomly selected. Results: Over a study period of 31/32 years, there was a significant decline in systolic and diastolic blood pressure in both sexes, whereas the prevalence of hypertension decreased only in women. There was an increase in hypertension awareness in both sexes over the entire study period with consistently higher rates in women. The proportion of individuals treated with antihypertensive drugs increased significantly in both sexes throughout the study, again with consistently higher rates in women. Control of hypertension increased significantly over the study period with consistently higher rates in women. The age-adjusted trends in blood pressure, prevalence, awareness, and treatment of hypertension were significantly different in men and women, always in favor of women. The age-adjusted trends in control of hypertension in treated patients were equally poor in both sexes. Conclusion: There are significant differences in longitudinal trends in blood pressure, prevalence, awareness, treatment, and control of hypertension between men and women, always in favor of women except for the control of hypertension in treated patients, where it is equally poor in both sexes.
RESUMEN
BACKGROUND: Compared with Western Europe, the decline in cardiovascular (CV) mortality has been delayed in former communist countries in Europe, including the Czech Republic. We have assessed longitudinal trends in major CV risk factors in the Czech Republic from 1985 to 2016/17, covering the transition from the totalitarian regime to democracy. METHODS: There were 7 independent cross-sectional surveys for major CV risk factors conducted in the Czech Republic in the same 6 country districts within the WHO MONICA Project (1985, 1988, 1992) and the Czech post-MONICA study (1997/98, 2000/01, 2007/08 and 2016/2017), including a total of 7,606 males and 8,050 females. The population samples were randomly selected (1%, aged 25-64 years). RESULTS: Over the period of 31/32 years, there was a significant decrease in the prevalence of smoking in males (from 45.0% to 23.9%; p < 0.001) and no change in females. BMI increased only in males. Systolic and diastolic blood pressure decreased significantly in both genders, while the prevalence of hypertension declined only in females. Awareness of hypertension, the proportion of individuals treated by antihypertensive drugs and consequently hypertension control improved in both genders. A substantial decrease in total cholesterol was seen in both sexes (males: from 6.21 ± 1.29 to 5.30 ± 1.05 mmol/L; p < 0.001; females: from 6.18 ± 1.26 to 5.31 ± 1.00 mmol/L; p < 0.001). CONCLUSIONS: The significant improvement in most CV risk factors between 1985 and 2016/17 substantially contributed to the remarkable decrease in CV mortality in the Czech Republic.

OBJECTIVES: To assess longitudinal trends in cardiovascular mortality and population mean blood pressure, prevalence, awareness, treatment, and control of hypertension in a representative Czech population sample from 1985 to 2007/2008. METHODS: Source data on mortality rates were provided by the Czech Statistical Office and further processed by the Institute for Health Information and Statistics of the Czech Republic. Six independent cross-sectional population surveys were conducted in 1985, 1988, 1992, 1997/1998, 2000/2001, and 2007/2008 with randomly selected men and women aged 25-64 years and resident in six districts of the Czech Republic (Praha-východ, Benesov, Pardubice, Chrudim, Cheb, and Jindrichuv Hradec). The total number of participants was 13 972. RESULTS: Since 1985, there has been a significant continuous, almost linear decline in standardized total, cardiovascular disease, ischemic heart disease, and stroke mortality (P < 0.001).There was a significant downward trend in the population mean SBP (from 133.6 ± 20.2 to 129.5 ± 18.5 mmHg; P < 0.001) and DBP (from 84.1 ± 11.3 to 82.5 ± 10.0 mmHg; P < 0.001) from 1985 to 2007/2008. This was associated with a significant decrease in the prevalence of hypertension only in women (from 42.5 to 37.2%; P < 0.001). Awareness of hypertension increased in both sexes (men, from 41.4 to 68.4%; women, from 58.9 to 71.4%; both P < 0.001) as did the number of individuals on antihypertensive medication (men, from 21.1 to 58.2%, women: from 38.9 to 58.9%; both P < 0.001). Control of hypertension improved significantly (from 3.9 to 24.6%) over the same period. CONCLUSION: The reduction in population blood pressure and improved hypertension control may have contributed substantially to the decrease in cardiovascular disease mortality in the Czech Republic.

OBJECTIVE: The aim of our study was to assess longitudinal trends in major CV risk factors in a representative population sample of the Czech Republic. METHODS: Three cross-sectional surveys of CV risk factors were conducted within the WHO MONICA project in six Czech districts in 1985 (n=2570), 1988 (n=2768), and 1992 (n=2343). In 1997/98, 2000/01, and 2007/08, another three screenings for CV risk factors (a 1% random sample, aged 25-64, mean age 45 years) were conducted in the six original districts (n=1990; 2055; and 2246, respectively). RESULTS: Over a period of 22/23 years, there was a significant decrease in the prevalence of smoking in males (from 45.0 to 30.5%; p<0.001) and no change in smoking habits in females. BMI increased in males and did not change in females. Both systolic and diastolic blood pressure decreased significantly in both genders, while the prevalence of hypertension declined only in females. Awareness of hypertension also rose as did the proportion of individuals treated by antihypertensive drugs in both genders. Hypertension control improved in either gender. A remarkable drop in total cholesterol was seen in both sexes (males: from 6.21 + or - 1.29 to 5.29 + or - 1.10 mmol/L; p<0.001; females: from 6.18 + or - 1.26 to 5.30 + or - 1.06 mmol/L; p<0.001). CONCLUSIONS: The striking improvement in CV risk factors documented between 1985 and 2007/8 most likely contributed to the decrease in CV mortality in the Czech Republic.

OBJECTIVE: To assess trends in blood pressure (BP) levels, prevalence, awareness, and control of hypertension in the Czech population from 1985 to 2000/01. DESIGN: Five independent cross-sectional population surveys conducted in 1985, 1988, 1992, 1997/98, and 2000/01. SETTING: Six, mostly rural, districts of the Czech Republic (Praha-východ, Benesov, Pardubice, Chrudim, Cheb, and Jindrichuv Hradec). PARTICIPANTS: Men and women aged 25-64 years randomly selected from six districts using the National Population Register/General Health Insurance Company Register (covering, by law, all citizens). The total number of participants was 11 726. MAIN OUTCOME MEASURES: We assessed the mean systolic BP, diastolic BP and pulse pressure, prevalence of hypertension (systolic BP > or = 140 mmHg and/or diastolic BP > or = 90 mmHg, or current treatment with antihypertensive drugs), awareness, treatment, and control of hypertension. RESULTS: Mean systolic BP, diastolic BP, and pulse pressure decreased significantly over a period of 15/16 years. This was associated with a significant decrease in the prevalence of hypertension (from 47.1 to 39.1%, P < 0.001) and with an increase in its awareness (from 49.5 to 67.2%, P < 0.001), use of antihypertensive medication (from 29.3 to 49.3%, P < 0.001), and hypertension control (from 3.9 to 17.0%, P < 0.001). Despite having lower BP values and prevalence of hypertension, females showed higher awareness of the disease, and were more frequently taking antihypertensive medication, and their hypertension was better controlled. CONCLUSION: The reduction in population BP and improved control of hypertension may have contributed to the decrease in cerebrovascular and coronary heart disease mortality in the Czech Republic. The positive longitudinal changes seen in the MONICA regions need not necessarily reflect the situation in the country as a whole. The situation is far from being optimal; a major problem is inadequate treatment of hypertension
