|---|---|---|---|---|
Prevalence | Self-reported | 17.4 (16.5–18.3) | 12.2 (11.5–13.0) | 6.1 (5.6–6.7) |
Measured to have risk factor | 23.9 (22.9–24.9)* | 37.3 (36.2–38.4)* | 4.5 (4.0–4.9)* | |
Accuracy of self-report | Overreported: Self-reported but no measured risk factor | 9.8 (9.1–10.5) | 8.1 (7.5–8.8) | 2.9 (2.6–3.3) |

Accurate, has disease: Self-reported and measured to have risk factor | 7.6 (7.0–8.2) | 4.1 (3.6–4.5) | 3.2 (2.8–3.6) | |
Accurate, does not have disease: Did not self-report and no measured risk factor | 66.3 (65.2–67.3) | 54.6 (53.4–55.7) | 92.6 (92.0–93.2) | |
Misreporting rate | Proportion of those measured to have risk factor that did not self-report | 68.4 (66.2–70.6) | 89.0 (87.9–90.2) | 28.6 (23.7–33.6) |
Proportion of those who self-reported that had no measured risk factor | 56.5 (53.8–59.2) | 66.6 (63.5–69.7) | 48.0 (43.3–52.6) |
