Background: Exposure to PM2.5 arising from solid fuel combustion is estimated result in ∼2.3 million premature deaths and 91 lost disability-adjusted life years annually. Interventions attempting mitigate this burden have had limited success reducing exposures levels thought provide substantive health benefits. Objectives: This paper reports exposure reductions achieved by a liquified petroleum gas (LPG) stove intervention for pregnant mothers the Household Air Pollution Intervention Network...
Household air pollution (HAP) from solid fuel use is associated with adverse birth outcomes, but data for exposure-response relationships are scarce. We examined associations between HAP exposures and birthweight in rural Guatemala, India, Peru, Rwanda during the Air Pollution Intervention Network (HAPIN) trial.
BACKGROUND: High quality personal exposure data is fundamental to understanding the health implications of household energy interventions, interpreting analyses across assigned study arms, and characterizing exposure-response relationships for air pollution.This paper describes collection Household Air Pollution Intervention Network (HAPIN), a multicountry randomized controlled trial liquefied petroleum gas stoves fuel among 3,200 households in India, Rwanda, Guatemala, Peru.OBJECTIVES: The...
BackgroundHousehold air pollution might lead to fetal growth restriction during pregnancy. We aimed investigate whether a liquefied petroleum gas (LPG) intervention reduce personal exposures household pregnancy would alter growth.MethodsThe Household Air Pollution Intervention Network (HAPIN) trial was an open-label randomised controlled conducted in ten resource-limited settings across Guatemala, India, Peru, and Rwanda. Pregnant women aged 18–34 years (9–19 weeks of gestation) were...
Traditional gravimetric instruments used for personal air pollution exposure measurements are often cumbersome and noisy do not offer real‐time assessment capability. The Enhanced Children’s MicroPEM (ECM) is a comparatively lightweight quiet instrument designed to capture both integrated filter‐based samples continuous (nephelometric) particulate matter with an aerodynamic diameter of 2.5 μ m or less (PM ) concentrations. We assessed the performance reliability collocated ECMs in subset...
The Household Air Pollution Intervention Network trial is a multi-country study on the effects of liquefied petroleum gas (LPG) stove and fuel distribution intervention women's children's health. There limited data exposure reductions achieved by switching from solid to clean cooking fuels in rural settings across multiple countries. As formative research 2017, we recruited pregnant women characterized impact personal exposures kitchen levels fine particulate matter (PM2.5) Guatemala, India,...
Pneumonia is the leading cause of death in children worldwide. Identifying and appropriately managing severe pneumonia a timely manner improves outcomes. Little known about readiness healthcare facilities to manage pediatric low-resource settings.
Assessment of personal exposure to PM2.5 is critical for understanding intervention effectiveness and exposure-response relationships in household air pollution studies. In this pilot study, we compared concentrations obtained from two next-generation monitors (the Enhanced Children MicroPEM or ECM; the Ultrasonic Personal Air Sampler UPAS) those with a traditional Triplex Cyclone SKC Pump (a gravimetric cyclone/pump sampler). We co-located cyclone/pumps an ECM UPAS obtain 24-hour kitchen...
Abstract Background Household air pollution (HAP) from solid fuel use is associated with adverse birth outcomes, but data on exposure-response relationships are limited. We examined associations between HAP exposures and birthweight in rural Guatemala, India, Peru, Rwanda during the Air Pollution Intervention Network (HAPIN) trial. Methods recruited 3200 pregnant women 9 <20 weeks of gestation. Women randomized to intervention arm received a liquified petroleum gas (LPG) stove pregnancy,...
Exposure to household air pollution is a leading cause of ill-health globally. The Household Air Pollution Intervention Network (HAPIN) randomized controlled trial evaluated the impact free liquefied petroleum gas stove and fuel intervention on birth outcomes maternal child health. As part HAPIN, an extensive exposure assessment was conducted. Here, we report PM 2.5 CO exposures young children (≤ 15 months old) reconstructed using Bluetooth-beacon based time-activity monitoring system...
Waste collection services are uncommon in rural areas of low-resource countries, causing waste accumulation and subsequent dumping burning garbage. Air pollution from household garbage burning, including plastics, has been observed Jalapa, Guatemala addition to air (HAP) cooking. Adolescent girls often help with these cooking tasks, but little is known about their exposures. We characterized 24-h exposures HAP adolescent by measuring fine particulate matter (PM2.5), black carbon (BC),...
Background Household air pollution adversely affects human health and the environment, yet more than 40% of world still depends on solid cooking fuels. The House Air Pollution Intervention Network (HAPIN) randomized controlled trial is assessing effects a liquefied petroleum gas (LPG) stove 18-month supply free fuel in 3,200 households rural Guatemala, India, Peru, Rwanda. Aims We conducted formative research Guatemala to create visual messages that support sustained, exclusive use LPG HAPIN...
Residential biomass burning is an important source of black carbon (BC) exposure among rural communities in low- and middle-income countries. We collected 7165 personal BC samples individual/household level information from 3103 pregnant women enrolled the Household Air Pollution Intervention Network trial. Women intervention arm received free liquefied petroleum gas stoves fuel throughout pregnancy; control continued use stoves. Median (IQR) postintervention exposures were 9.6 μg/m3...
Exposure to household air pollution has been linked adverse health outcomes among women aged 40–79. Little is known about how shifting from biomass cooking a cleaner fuel like liquefied petroleum gas (LPG) could impact exposures for this population. We report 24-h particulate matter (PM2.5), black carbon (BC), and monoxide (CO) 40 <80 years participating in the Household Air Pollution Intervention Network trial. 209 participants were randomized intervention received an LPG stove continuous...
Abstract Background Exposure to PM 2.5 arising from solid fuel combustion is estimated result in approximately 2.3 million premature deaths and 90 lost disability-adjusted life years annually. ‘Clean’ cooking interventions attempting mitigate this burden have had limited success reducing exposures levels that may yield improved health outcomes. Objectives This paper reports exposure reductions achieved by a liquified petroleum gas (LPG) stove intervention for pregnant mothers the Household...
Waste collection services are uncommon in rural areas of low-resource countries, causing waste accumulation and subsequent dumping burning garbage. In addition to household air pollution (HAP) from cooking, garbage burning, including plastics, has been observed Jalapa, Guatemala. Adolescent girls often help with cooking tasks, but little is known about their exposures. To characterize exposures HAP pollutants adolescent by measuring fine particulate matter (PM2.5), black carbon (BC), urinary...
Background and Aim Low birth-weight is a leading contributor to the burden of disease in low- middle-income countries (LMICs). Household air pollution (HAP) has been reported impact birth-weight, but evidence quantitative exposure-response relationships limited. As part multi-country Air Pollution Intervention Network (HAPIN) trial, we examined associations between prenatal exposure HAP as well weight-for-age z-scores, among 3200 pregnant women (recruited 9 <20 weeks gestation).
