General knowledge on hypertension among study participants using three different forms of classification
| Question (% of the overall population giving a right answer) |
Forms of classifying participants (% with a right answer by category, Χ2 statistic) |
||
|---|---|---|---|
| By years being diagnosed (3 incremental levels) | By % of follow up visits with the same doctor (3 incremental levels) | By knowledge of blood pressure levels (Yes/No answer) | |
| Hypertension stands for high blood pressure (67) | 63/69/68 (6.1)* | 57/74/70 (32.7)* | 77/59 (55.7)** |
| The two BP numbers stands for systolic and diastolic BP (8) | 8/7/7 (0.1) | 4/9/9 (11.9)** | 13/3 (52.3)** |
| BP treatment goals are < 140 and < 90 (43) | 41/41/45 (2.1) | 33/48/46 (27.1)* | 56/32 (87.8)** |
| If BP is not within goals additional medications may be needed (58) | 59/59/58 (0.3) | 54/65/57 (10.4)* | 67/52 (35.1)** |
| 3–4 of the above questions right (26) | 26/26/26 (0.1) | 17/34/28 (36.8)** | 40/15 (128.4)** |
