Long-term effects of cooking with liquefied petroleum gas or biomass on linear growth trajectories from birth to the pre-school years in Puno, Peru: a prospective cohort study.

ABSTRACT:

Background

Household air pollution (HAP) is a major global health risk. Observational studies link HAP exposure to impaired child growth, but randomized controlled trial (RCT) evidence is inconsistent.

Methods

We followed children born during an RCT of an 18-month liquefied petroleum gas (LPG) intervention among 800 pregnant women in Puno, Peru. We measured personal exposures to fine particulate matter (PM_2.5) and carbon monoxide (CO) three times during pregnancy and three times during infancy. We measured length quarterly between birth and 12 months and height once between age 2-4 years. We assessed the effect of the LPG intervention on growth trajectories and evaluated exposure-response associations between height-for-age z-score (HAZ) and PM_2.5 or CO
