Table 3.
Demographic and anthropometric characteristics of the three blood pressure groups, by sex.
| Normotensives (1) | P Value (1 vs. 2) | Incident Hypertensives (2) | P Value (1 vs. 3) | Self-Reported Hypertensives (3) | P Value (2 vs. 3) | ||||||||||
| F (n = 142) | M (n = 281) | F (n = 53) | M (n = 163) | F (n = 123) | M (n = 226) | ||||||||||

BMI: body mass index; WHR: waist to hip ratio; SBP: systolic blood pressure; DBP: diastolic blood pressure; NS: not significant (p > 0.05); Incident Hypertensives are SR normotensives with high blood pressure. The differences between the three methods are tested using Tukey's method, adjusted for sex.
