INDOOR AIR POLLUTION FROM BIOMASS STOVES AS A RISK FACTOR FOR ACUTE RESPIRATORY INFECTIONS IN KENYA

摘要

55 randomly-selected households (including 93 infants and children; 229 individuals between 5 and 49 years of age; and 23 at ages ≥ 50) in central Kenya were followed up for more than 2 years. Longitudinal data on acute respiratory infections (ARI) and acute lower respiratory infection (ALRI) were recorded in weekly clinical examinations. Exposure to PM_(10) was estimated from 210, 14-hour days of continuous real-time monitoring of particulate matter concentration under the conditions of actual use as well as the location and activities of household members, supplemented by data on spatial dispersion of pollution and interviews. Estimates of risk associated with exposure to indoor smoke (measured by PM_(10) concentration) are presented using linear and logistic models for average daily exposure below and above 1000 μg/m~3. There was increased risk for both total ARI and ALRI for those at higher exposure in both age groups.
