The effect of the World Kidney Day campaign on the awareness of chronic kidney disease and the status of risk factors for cardiovascular disease and renal progression.

BACKGROUND

Chronic kidney disease (CKD) is a worldwide problem. We describe the trends in CKD awareness before and after the World Kidney Day (WKD) campaign and the impact of the WKD campaign in increasing awareness and appropriate management of the risk factors for cardiovascular disease and renal progression.

METHODS

We selected 57 718 people who had undergone a routine health check-up.

RESULTS

The average CKD awareness was 3.1% (95% CI: 2.6-3.7%) and was increased with progressing CKD stage. The awareness was increased from 1.1% before the WKD campaign to 5.8% after the campaign (P < 0.001). CKD awareness in the post-WKD period was increased in CKD stages 2 (OR 4.535: 95% CI: 2.044-10.062) and 3 (OR 6.614: 95% CI: 4.282-10.217) and profoundly increased in stage 4 (OR 13.800: 95% CI: 2.127-89.524), compared to the pre-WKD period. In the CKD-aware group compared to the CKD-unaware group, the awareness of diabetes mellitus (90.0% versus 54.2%, P < 0.001) and hypertension (87.2% versus 64.7%, P < 0.001) was higher and the levels of systolic blood pressure (116.9 +/- 1.0 versus 120.1 +/- 0.2, P < 0.01) and serum cholesterol (198.3 +/- 2.7 versus 205.0 +/- 0.5, P < 0.05) were lower by covariance analysis.

CONCLUSIONS

The WKD campaign had a positive impact on the awareness and control of risk factors in CKD subjects but the absolute frequency of CKD awareness still remains undesirable in Korea. We need new campaign strategies to publicize the importance of early diagnosis and appropriate management of CKD.
