Exposure during pregnancy to household air pollution caused by the burning of solid biomass fuel is associated with adverse health outcomes, including low birth weight. Whether replacement a cookstove liquefied petroleum gas (LPG) would result in an increase weight unclear.
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...
Exposure to household air pollution is a risk factor for severe pneumonia. The effect of replacing biomass cookstoves with liquefied petroleum gas (LPG) on the incidence infant pneumonia uncertain. We conducted randomized, controlled trial involving pregnant women 18 34 years age and between 9 less than 20 weeks' gestation in India, Guatemala, Peru, Rwanda from May 2018 through September 2021. were assigned cook unvented LPG stoves fuel (intervention group) or continue cooking (control...
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,...
Abstract Lead (Pb) and cadmium (Cd) are metals that occur naturally in the environment present biomass fuels, such as wood. When these fuels burned, they can release Pb Cd into air, leading to exposure through inhalation. Studies of health outcomes suggest harmful impacts, including cardiovascular diseases. We assessed baseline associations between concentrations dried blood spots with systolic diastolic pressure (SBP, DBP) among women Household Air Pollution Intervention Network (HAPIN)...
Objective Household waste burning, especially of plastics, is a major, but unaddressed environmental and health hazard in countries that lack infrastructure to properly manage waste. This study will implement village-level community working groups aim reduce household plastic burning improve health-related quality life women reproductive age rural Guatemala. Methods Using type 1 hybrid-effectiveness-implementation design, we randomize 16 villages Jalapa, Guatemala randomly select 400 (25...
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.
Household air pollution (HAP) from cooking with solid fuels used during pregnancy has been associated adverse outcomes. The Air Pollution Intervention Network (HAPIN) trial was a randomized controlled that assessed the impact of liquefied petroleum gas (LPG) stove and fuel intervention on health in Guatemala, India, Peru, Rwanda. Here we investigated effects LPG stillbirth, congenital anomalies neonatal mortality characterized exposure-response relationships between personal exposures to...
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 Rationale The spread of severe acute respiratory syndrome coronavirus-2 has suspended many non-COVID-19 related research activities. Where restarting activities is permitted, investigators need to evaluate the risks and benefits resuming data collection adapt procedures minimize risk. Objectives In context multicountry Household Air Pollution Intervention (HAPIN) trial conducted in rural, low-resource settings, we developed a framework assess risk each activity guide protective...
Household air pollution from solid cooking fuel use during gestation has been associated with adverse pregnancy and birth outcomes. The Air Pollution Intervention Network (HAPIN) trial was a randomized controlled of free liquefied petroleum gas (LPG) stoves fuelin Guatemala, Peru, India, Rwanda . A primary outcome the main to report effects intervention on infant weight. Here we evaluate LPG stove spontaneous abortion, postpartum hemorrhage, hypertensive disorders pregnancy, maternal...
We conducted a cross-sectional study with 208 HIV-uninfected and 188 HIV-infected women in Uganda Zimbabwe to investigate differences median CD4 counts. Absolute counts were determined by flow cytometry. Multivariate analyses used examine the association of country HIV-infection status on Median significantly lower than overall (649 783 cells/mm 3 , P = 0.009) among (470 614 0.003). In separate multivariable models, ( 0.014) infected < 0.001) women, controlling for age, contraceptive...
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...
Background Household air pollution (HAP) is a leading environmental risk factor accounting for about 1.6 million premature deaths mainly in low- and middle-income countries (LMICs). However, no multicounty randomized controlled trials have assessed the effect of liquefied petroleum gas (LPG) stove intervention on HAP maternal child health outcomes. The Air Pollution Intervention Network (HAPIN) was first to assess this by implementing common protocol four LMICs. Objective This manuscript...
Randomized controlled trials (RCTs) that evaluate the efficacy of an intervention remain underutilized in community-based environmental health research. RCTs use a pragmatic design emphasize effectiveness interventions complex, real world settings. Pragmatic may be especially relevant when address social and determinants threaten equity. The revised Explanatory Continuum Indicator Summary (PRECIS-2) is validated tool developed 2015 by trialists to ensure clinical are designed fit their...
In Brief Objective We conducted a randomized trial to determine whether pretreatment with meclizine reduces the incidence of nausea and vomiting associated Yuzpe regimen emergency contraception. Methods randomly assigned 343 women aged 18–45 years who were not at risk for pregnancy 50 mg meclizine, placebo, or no drug 1 hour before first two doses contraceptive pills. asked participants complete three questionnaires over following 48 hours. Results The was 47% in group pretreated 64% other...
Here, we present a visual representation of standard procedures to collect population-level data on personal exposures household air pollution (HAP) from two different study sites in resource-constrained setting Tamil Nadu, India. Particulate matter PM2.5 (particles smaller than 2.5 microns aerodynamic diameter), carbon monoxide (CO), and black (BC) were measured pregnant mothers (M), other adult women (OAW), children (C) at various times over 4 year period. In addition, stove usage...
