Lessons learned from the Philadelphia Collaborative Preterm Prevention Project: the prevalence of risk factors and program participation rates among women in the intervention group

Table 3 Risk factor prevalence, acceptance rates and rates of minimal participation in PCPPP treatment protocols ¹

¹The number of women assessed (the denominator for prevalence) in all cases except for urogenital track infection and periodontal disease was 471. For periodontal disease 446 women were assessed by the dental hygienist; 25 women could not be assessed for periodontal disease because the hygienist experienced a temporary illness during the course of the study and was therefore unavailable at the time their clinic visit occurred. These 25 women were subsequently lost to follow-up. For urogenital tract infection 464 women were assessed/swabbed for infections; over the course of the study a total of 7 women had to leave the clinic before they could be tested for infections and were subsequently lost to follow-up.
²A women was classified as having accepted if she was identified as having a risk factor and agreed to receive the risk-appropriate treatment or service as defined in Table 1.
³See last column of Table 1 for explanation of how “participation” was defined.
