Figure 1.
From the population of 21,210 female participants in the NHANES 1999–2006, women who were younger than 20-year old (n = 10,509), pregnant at the interview (n = 1,173), did not complete interview and exam (n = 662), did not report previous live birth delivery (n = 2,308), or were in other race group (n = 209) were excluded. This led to a target population of 6,349 women. Women who did not answer the pregnancy history questions were excluded from the target population (n = 42). Therefore, a total of 6,307 women were included in the analysis.

Prevalence of hypertension in white, black, and Hispanic women.
Overall, black women had higher prevalence of hypertension compared to white and Hispanic women. Within each race/ethnicity group, women who had a SGA-LBW or Preterm-LBW infant had higher prevalence of HTN than the BW≥2,500 g group. It was of note that even black women with BW≥2,500 g infant delivery had higher prevalence of hypertension compared to any group of white and Hispanic women.
