Feasibility of an ADAPTive Intervention to Improve Food Security and Maternal-Child Health

Официальное название

Feasibility of an ADAPTive Intervention to Improve Food Security and Maternal-Child Health (ADAPT-MCH)

Обзор

Food insecurity affects up to 30% of pregnancies and leads to worse health in pregnant people and their children, including an increased risk of gestational diabetes, pre-term birth, and future cardiometabolic chronic conditions (e.g., type 2 diabetes and obesity). Interventions are being utilized to address food insecurity in clinical care settings, but patients differ in the support needed to reduce food insecurity and health systems have limited resources to invest in these interventions. Rather than a single intervention, adaptively allocating interventions could be a more effective, equitable, and efficient approach to improve food security; the objectives of this pilot study are to determine the feasibility of recruiting, retaining, and adaptively providing food insecurity interventions to pregnant patients in anticipation of a large, definitive trial in the future.

Подробное описание

The US is facing a maternal and infant health crisis. Each year in the US there are \>700 maternal deaths and \>60,000 life-threatening pregnancy events. Despite decreasing in other high-income countries, maternal mortality has increased in recent years in the US with a staggering 1210 maternal deaths in 2019. Importantly, maternal deaths in the US are now less likely to be due to direct complications of childbirth, and are increasingly due to endocrine (e.g. gestational diabetes (GDM)) or cardiovascular (e.g. pre-eclampsia) conditions directly related to obesity and other nutrition-related chronic diseases. One significant contributor to maternal mortality is food insecurity (FI), or the lack of consistent access to the food needed for a healthy life. In 2023, 13.5% of US households, (\>40 million people), were food insecure. Households with young children have higher rates of FI. Also, up to 30% of pregnancies are impacted by FI. Pregnant and postpartum women are especially vulnerable to the impacts of FI as they have increased nutritional requirements for the growing fetus and while breastfeeding. FI has been associated with inadequate or excessive gestational weight gain, GDM, and pregnancy-induced hypertension. Excess retained weight after pregnancy has important health consequences including development of type 2 diabetes. GDM and gestational weight retention also confer higher risk of complications in subsequent pregnancies and future cardiovascular disease. Additionally, FI is associated with increased risk of preterm birth and infants being born low birth weight, affecting children's growth trajectories and future risk of developing obesity.

To address the high prevalence of FI and its impact on health, national healthcare organizations, including the Centers for Medicare and Medicaid (CMS) and The American College of Obstetricians and Gynecologists, have recommended that health systems address FI as a routine part of clinical care. The integration of interventions to address FI in different populations, particularly those with nutrition-related conditions, has been termed "Food is Medicine". CMS has been piloting Food is Medicine interventions as part of Medicaid reform in several states, including North Carolina. Three "Food is Medicine" interventions that are being studied and used by health systems and insurers include: 1) referring patients to government benefits intended to support nutrition or directly providing food through the use of 2) produce prescriptions and 3) medically-tailored meals. Despite the growing use of FI interventions in clinical care settings, a 2023 systematic review highlighted the need for more research on healthcare system-based interventions to reduce FI in pregnancy.

Вмешательства

• Поведенческое Produce prescription
  Participants randomized to this arm will receive $10 worth of produce delivered to their home weekly. Participants will receive a weekly delivery of produce for 3 months.
• Поведенческое Medically tailored meals
  Medically tailored meals will be delivered weekly to participant's homes for 3 months. During the 3 months, participants will receive 10 medically-tailored refrigerated or frozen meals (5 lunches and 5 dinners) delivered to their home weekly. All meals are planned by a registered dietician. Meals have minimal preparation time, can be heated by stove, oven, or microwave, and will be provided free-of-charge. Because the meals are medically tailored, participants are asked not to share them. Adhere
• Поведенческое Electronic health record WIC referral
  Participants randomized to this intervention will be referred to their county WIC program through an already developed electronic referral process. To enable WIC offices to receive referrals and easily communicate with healthcare teams, our EHR also offers a community provider-facing, read-only EHR version. We have already successfully provided WIC staff with access and training for our ongoing WIC screening and referral pilot in pediatrics.
• Поведенческое Electronic health record WIC referral + care navigation
  Participants will receive the same intervention as the electronic WIC referral. In addition, a patient care navigator will meet with the participant at enrollment to discuss any anticipated barriers to accessing WIC. The purpose of the visit is to build rapport and trust and to identify any social and structural barriers to enrolling in WIC. The navigator will also contact participants at 2 weeks to discuss any additional barriers reported and as necessary after the baseline visit. Specific coun
