Prevalences of suboptimal cholesterol concentrations, eligibility for treatment, treated and controlled hypercholesterolaemia for different time periods and separately for primary and secondary prevention, weighted by the age and gender distribution of the general Dutch population and corrected for intra-person variability.
| Respondents | Suboptimal cholesterol concentrations | Eligible for treatment | Treated | Controlled* | |
|---|---|---|---|---|---|
| 1987–92 | 41 647 | 27 457 (59.6%) | 1739 (5.1%) | 165 (10.1%) | 12 (7.7%/0.8%) |
| 1993–97 | 21 776 | 12 607 (51.7%) | 980 (6.6%) | 265 (27.0%) | 71 (27.3%/7.4%) |
| Primary prevention** | 61 918 | 38 839 (62.7%) | 1494 (3.8%) | 294 (19.7%) | 36 (12.2%/2.4%) |
| Secondary prevention** | 1 505 | 1 225 (81.4%) | 1225 (100.0%) | 136 (11.1%) | 47 (34.6%/3.8%) |
*
% of those treated and percentage of those eligible for treatment, respectively
**
correction for the age and gender distribution not possible, because data on the age and gender distribution of the Dutch population among those with or without pre-existing CHD was not available.
