Introduction: Estimation of absolute risk for cardiovascular death (SCORE 2005) is recently basic stratification procedure in decision for therapy of arterial hypertension and dyslipidemia in primary and secondary prevention. Extrapolation of AR on age of 60 years allows to compare also cohorts with different age.
Methods: We examined 1241 "blue collar" workers (786 males, 455 females) in factory Duslo Šala (project Omron) (42.8±9.90 yrs) and 296 "white collar" workers (100 males and 196 females) from Slovak National Bank and Prvá Stavebná Sporiteľna (project Whico) (40.1±8.83 yrs).
Results: White collars exhibited significantly lower absolute risk extrapolated to age of 60 years both in males (3.8±1.86 vs 5.3±2.63; p<0.001) and females (1.6±0.79 vs 2.1± 1.45; p<0.01). Risk of males in both groups were twice as high as females'. "White collar" workers had significantly lower blood pressure, however, females in both groups had lower systolic (SBP) and diastolic blood pressure (DBP) about 5 mm Hg compared to males (see Table).
| SBP [mmHg] | DBP [mmHg] | |||||
| "White" | "Blue" | Sign. | "White" | "Blue" | Sign. | |
| Males | 119.8±12.2 | 130.0±18.4 | p<0.001 | 79.7±9.7 | 86.1±10.5 | p<0.001 |
| Females | 114.8±14.3 | 123.8±18.9 | p<0.002 | 75.8±9.2 | 80.6±10.2 | p<0.001 |
| Sign. | p<0.001 | p<0.001 | p<0.01 | p<0.001 |
Conclusion: "White collar" workers exhibited significantly lower absolute risk for cardiovascular death and lower blood pressure in comparison with "blue collars“ of analogous age. Moreover, males in the both groups had almost twice higher risk in comparison with females.
