Birth-related outcomes, such as birth weight, have lifelong impacts on
health. Home visiting (HV) is an established approach to improve the health of
children and families, parenting practices, and connections to social and health
services. Many HV programs target first-time mothers, in part because HV
activities related to a first-birth may improve birth outcomes for subsequent
children, but few researchers have examined these effects. We will link data
from a statewide HV program (Nurturing Families Network [NFN]) to birth
certificate data to create comparison groups and measure outcomes in this
observational study. Specifically, we will compare birth outcomes for NFN
second-children (n = 3000) to those for: (a) first-child older
siblings whose birth/gestation led to NFN enrollment (n =
3000); (b) second children of families who were screened as eligible for NFN,
but not offered the program due to home visitor availability and other
logistical reasons (n = 650); and (c) non-NFN second children
in a propensity-score-matched group created using the likelihood of enrollment
in NFN based on maternal health, demographics, and neighborhood characteristics
(n = 6000). The outcomes we will examine are birth spacing,
prenatal care received, cesarean section rate, gestational age, and birth weight
in second-children. We will also examine the associations between program
attendance (i.e., missed visits, dropout) and birth outcomes, that will generate
evidence that may be used in programmatic decisions regarding continued funding
and/or modification of NFN, prioritization of specific retention efforts, and
targeting of first-time mothers. Use of this evidence should improve outcomes
for future NFN families and may inform similar programs.
