Article Synopsis
  • Residential biomass burning significantly contributes to black carbon (BC) exposure in rural communities, especially among pregnant women in low- and middle-income countries.
  • In a study involving 3103 pregnant women, those who received liquefied petroleum gas stoves showed much lower BC exposure (2.8 μg/m) compared to those using traditional biomass stoves (9.6 μg/m).
  • The study identified primary stove type as the strongest predictor of BC exposure, and highlights the need to consider various factors, such as kitchen location and adherence to stove use, to improve the efficacy of cookstove intervention trials.

Background: Maternal overweight and obesity has been associated with poor lactation performance including delayed lactogenesis and reduced duration. However, the effect on human milk composition is less well understood.

Objectives: We evaluated the relationship of maternal BMI on the human milk metabolome among Guatemalan mothers.

Article Synopsis
  • Waste collection is limited in rural low-resource areas, leading to garbage accumulation and environmental issues like air pollution from burning waste, particularly in places like Jalapa, Guatemala.
  • A study examined the exposure of 60 adolescent girls (ages 13-17) to household air pollution (HAP) and garbage burning, comparing those using wood-burning stoves to those with gas stoves.
  • Results showed that gas stove users experienced significantly lower levels of fine particulate matter and black carbon, suggesting gas stoves help reduce harmful exposure to air pollution among adolescents involved in household cooking.

The Household Air Pollution Intervention Network trial is a multi-country study on the effects of a liquefied petroleum gas (LPG) stove and fuel distribution intervention on women's and children's health. There is limited data on exposure reductions achieved by switching from solid to clean cooking fuels in rural settings across multiple countries. As formative research in 2017, we recruited pregnant women and characterized the impact of the intervention on personal exposures and kitchen levels of fine particulate matter (PM) in Guatemala, India, and Rwanda.

Rationale: The spread of severe acute respiratory syndrome coronavirus-2 has suspended many non-COVID-19 related research activities. Where restarting research activities is permitted, investigators need to evaluate the risks and benefits of resuming data collection and adapt procedures to minimize risk.

Objectives: In the context of the multicountry Household Air Pollution Intervention (HAPIN) trial conducted in rural, low-resource settings, we developed a framework to assess the risk of each trial activity and to guide protective measures.

Household air pollution (HAP) generated from solid fuel combustion is a major health risk. Direct measurement of exposure to HAP is burdensome and challenging, particularly for children. In a pilot study of the Household Air Pollution Intervention Network (HAPIN) trial in rural Guatemala, we evaluated an indirect exposure assessment method that employs fixed continuous PM monitors, Bluetooth signal receivers in multiple microenvironments (kitchen, sleeping area and outdoor patio), and a wearable signal emitter to track an individual's time within those microenvironments.
