title: Primiparous outcomes and future pregnancy health behaviors.
abstract: OBJECTIVE
  To examine the impact of repeat, G2, and outcomes of first, G1, (previous livebirth, PLB, or stillbirth, PSB) pregnancies on health-compromising behaviors (HCB).
  
  
  METHODS
  Retrospective cohort study of 137,374 pregnancies in Kansas City, MO, 1990 through 2009, using birth certificate database.
  
  
  RESULTS
  Overall HCB rate was 17% and increased with G2 and PSB (G1=12% v G2-PLB=21% v G2-PSB=29%, p < .001). Compared to G2-PLB, the odds of HCB increased for G2-PSB (OR=1.42; 95%CI 1.10, 1.82) and decreased for G1 (0.54; 0.52, 0.56).
  
  
  CONCLUSIONS
  Women are more likely to engage in HCB during their second pregnancy, especially those who lose their first pregnancy. This finding is evidence for promoting effective inter-conception health care at post-partum and primary care visits.
