Study design and protocol for nourishing beginnings, an integrated service delivery model addressing food insecurity and social needs of low-income pregnant individuals

BACKGROUND: Nourishing Beginnings is an integrated referral and service delivery model supporting Medicaid-eligible pregnant individuals by providing increased nutritional food access throughout pregnancy up to three months postpartum, through community health workers (CHW), who simultaneously address and provide support for social service needs of the client. METHODS: To study the impact of possible interventions on food security, the program includes two distinct interventions each paired with traditional CHW services, nutrition educational materials, and provision of basic essential cooking tools. Interventions consist of either bi-weekly home food delivery from the local food bank or bi-weekly financial assistance with healthy food access navigation. The study population consists of 160 pregnant individuals (18 or older, <22 weeks pregnant; 80 per intervention arm) who were referred to a countywide Pathways Community HUB (HUB), a community-based care coordination network that uses an evidence-based model to connect at-risk individuals to resources that address medical, social, economic, and behavioral health needs. Key data collection occurs at baseline, eight weeks after intervention begins, near delivery (36-38 weeks gestation), and three months postpartum. Intervention groups are compared to each other as well as against HUB historical controls and a concurrent matched sample from local Medicaid data. CONCLUSION: The goal of Nourishing Beginnings is to improve long-term health outcomes (i.e., maternal and infant) both directly and mediated through a set of proximal outcomes, including prenatal care, food security, diet and nutrition, reported race discrimination and psychosocial factors including depression, stress, healthy eating self-efficacy, and social support.
