Household Air Pollution and Health: A Multi-country LPG Intervention Trial

This study is a randomized controlled trial of liquefied petroleum gas (LPG) stove and fuel distribution in 3,200 households in four countries (India, Guatemala, Peru, and Rwanda). Following a common protocol, each intervention site will recruit 800 pregnant women (aged 18-34 years, 9 - \<20 weeks gestation) and will randomly assign half their households to receive LPG stoves and an 18-month supply of LPG. Control households are anticipated to continue to cook primarily with solid biomass fuels and will receive compensation based on a uniform set of trial-wide principles, customized to each site based on formative research. The mother will be followed along with her child until the child is 1 year old. The researchers estimate that 15% of households will have a second, non-pregnant older adult woman (aged 40 to \<80 years) who will also be enrolled at baseline and followed during the 18-month follow-up period. To optimize intervention use, the researchers will implement behavior change strategies informed by previous experiences and formative research in Year 1. This study will assess cookstove use, conduct repeated personal exposure assessments of household air pollution, and collect dried blood spots and urinary samples for biomarker analysis and biospecimen storage. The primary outcomes are low birth weight, severe pneumonia incidence, and stunting of the child, and systolic blood pressure in the older adult woman. Participants in India, Guatemala and Rwanda will be followed until the child is 5 years old to assess the longer-term effects of the intervention.

Generic Database of Very Low Birth Weight Infants

The Generic Database (GDB) is a registry of very low birth weight infants born alive in NICHD Neonatal Research Network (NRN) centers. The GDB collects observational baseline data on both mothers and infants, and the therapies used and outcomes of the infants. The information collected is not specific to a disease or treatment (i.e., it is "generic"). Data are analyzed to find associations and trends between baseline information, treatments, and infant outcome, and to develop future NRN trials.

Global Survey on Newborns' HOspitalisation and Parental Experiences - the HOPE Study

This study aims to explore parents' experiences and emotional burdens related to their newborn's hospital stay using an online survey. Our target population consists of parents of newborns born preterm, with low birthweight, or critically ill. Particularly the presence of infant- and family-centred developmental care (IFCDC) principles as well as support through political framework conditions will be investigated.

Follow-up Visit of High Risk Infants

The NICHD Neonatal Research Network's Follow-Up study is a multi-center cohort in which surviving extremely low birth-weight infants born in participating network centers receive neurodevelopmental, neurosensory and functional assessments at 22-26 months corrected age (Infants born prior to July 1, 2012 were seen at 18-22 months corrected age). Data regarding pregnancy and neonatal outcome are collected prospectively. The goal is to identify potential maternal and neonatal risk factors that may affect infant neurodevelopment.
