The objective of the study was to determine the association of home visiting with subsequent pregnancy outcomes.


Retrospective study of Ohio mothers delivering their first infant from 2007 to 2009. First, we compared mothers enrolled in home visiting with a matched eligible group. Second, we compared outcomes within home visiting based on program participation (low <25% of recommended home visits, moderate 25 to 75%, high 75 to 100% and very high >100%). Time to subsequent pregnancy within 18 months was evaluated using Cox proportional hazards regression; logistic regression tested the likelihood of subsequent preterm birth.


Of 1516 participants, 1460 were matched 1:1 to a comparison mother (n = 2920). After multivariable adjustment, enrollment was associated with no difference in pregnancy spacing or subsequent preterm birth. Among those enrolled, moderate vs low participants had reduced risk of repeat pregnancy over 18 months (hazard ratio 0.68, P = 0.003).


Increased pregnancy spacing is observed among women with at least moderate home visiting participation.
