Birth Weight

Allergy prevalence is increasing steadily with some describing as the "epidemic of the twenty-first century". Maternal diet during pregnancy has been linked to offspring allergy risk, so it represents a potential target for allergy prevention. The Mediterranean Diet (MD) is considered one of the healthiest dietary models which exerts regulatory effects on immune system, due to the synergistic and interactive combinations of nutrients. We aim to study the effects of MD in pregnancy on the onset of allergic diseases at 2 years of age in the offspring.

Gestational diabetes mellitus (GDM) is a transient hyperglycemic condition identified during pregnancy in women without a history of chronic diabetes. Evidence indicates that GDM can lead to various adverse health outcomes, including preterm birth, progression to pre-diabetes, and type 2 diabetes after delivery in mothers. Notably, GDM is becoming increasingly prevalent among Asian pregnant women due to rising rates of overweight and obesity, as well as genetic susceptibility. Despite growing recognition of GDM, its treatment efficiency and efficacy remain poor, primarily due to its heterogeneity, which is underpinned by various pathophysiological mechanisms. Therefore, a better understanding of GDM heterogeneity can aid clinicians in providing more targeted treatment and follow-up strategies for GDM mothers. This study aims to define GDM phenotypes based on in vivo cardio-metabolic profiles and treatment response during pregnancy, utilizing advanced technologies such as continuous glucose profiling and untargeted metabolite profiling. In this proposed 3-year pregnancy cohort study, the investigators will recruit 800 overweight or obese Asian pregnant women in early pregnancy, without a history of diabetes, and follow them through to delivery. The goal of the study is to develop systematic antenatal and postnatal screening, treatment, and intervention guidelines for mothers with GDM.

Background: This programme effectiveness study responds to the need for evidence on the effect on birthweight of switching from iron-folic acid supplementation (IFA) to multiple micronutrient supplementation (MMS) as part of routine antenatal care in Ethiopia. A 2019 meta-analysis of trial data reported a mean improvement of 35g in newborn birthweight amongst newborns born to women who took MMS in pregnancy compared to those who took IFA. Responding to this evidence, in 2020 the World Health Organisation updated its global guideline on MMS from 'not recommended' to 'recommended in the context of rigorous research'. The guideline identifies priority research being 'to establish the impact of switching routine antenatal IFA to MMS on important health outcomes, equity, acceptability, feasibility, sustainability and health-care resources in different country settings.' In 2022 the Ministry of Health of Ethiopia (MoH), will change from MMS to IFA in a set of pilot districts. EPHI and LSHTM have been asked to evaluate the effect of this change on mean birthweight and propose the current trial for this purpose. The overall aim is to evaluate the programme effectiveness on mean birthweight of providing MMS as part of routine antenatal care, compared to providing IFA. Findings will support the MoH to make evidence-informed decisions about the large-scale implementation of MMS in Ethiopia and also contribute to the global evidence base on the effectiveness of MMS in a programmatic setting. Methods: A two-arm cluster randomized trial will be used to estimate the effect of the programme change on mean birthweight, with cost-effectiveness and process evaluations embedded in the trial design. Women aged 15-49 who deliver a live born child in a study district health facility (mother/infant dyads) will be eligible for enrolment in the study. The primary outcome measure will be birthweight, recorded in facilities at the time of birth as part of the routine maternity care. Secondary objectives include costs of providing MMS, acceptability of MMS, adherence to antenatal micronutrient supplementation and implementation challenges.

Visfatin, released in maternal milk at different concentrations related to the maternal conditions, could act as a biomarker with a prognostic/predictive value to determine different newborn clinical conditions, particularly the weight loss of the neonate.

In this study, at least 400 women with high-risk of pregnancy hypertension will use a wearable device to monitor the blood pressure during gestational age from 12 weeks to 28weeks. The observed outcomes including maternal and offspring. Participants were from three hospital including Shanghai Xinhua Hospital, Jiaxing Maternal and Child Health Hospital and Peking University Third Hospital. Pregnant women were randomly divided into control group (routine delivery examination group) and intervention group (routine delivery examination group + use of wearable blood pressure monitoring device group), 200 cases each.

This study is an evaluation of the Fresh Rx: Nourishing Healthy Starts program administered by Operation Food Search, a St. Louis-based nonprofit organization. The program provides food and nutrition supports to food insecure pregnant women in conjunction with integrative care services in order to improve health and birth outcomes for both the mother and the child. The purpose of this study is to test the efficacy of this approach through a field experiment, and to assess the extent to which these services can provide cost savings to the healthcare system.
