Abstract

Background The type of cooking fuel used in households can expose the members to polluted air which has been shown to have multiple health effects. We describe the trend in household air pollution (HAP) caused by the type of cooking fuel used in Ugandan households from 2001 to 2016 and explore the household factors associated with it. Methods This was a retrospective analysis of four datasets of Ugandan demographic and health surveys (DHS) conducted from 2000/2001 to 2016 with the household as the unit of analysis. We included variables that described the households, the type of cooking fuel, and where the food was cooked. A household was considered to have exposure to HAP if they used cooking fuels like coal, charcoal, wood, straw/shrubs/grass, crops, or animal dung for cooking. Bivariate and multivariate logistic regression was used to determine the association between household characteristics and exposure to household air pollution (HAP) from the most recent DHS of 2016. Results A total of 45,376 households were included in the study. In all the surveys, the majority of the households were rural (74.33–85.11%), were headed by a male (68.98–72.46%), and with their highest educational attainment as incomplete primary education (37.21–42.44%). In all the surveys, the majority of the households used wood as a cooking fuel (71.69–82.08%). Most of the households were exposed to HAP (96.69–99.80%). From the multivariate logistic regression analysis, households with a household head having attained either complete secondary education [Adjusted Odd ratio: 0.13, 95% Confidence interval (0.03–0.58), p-value = 0.008] or higher education [Adjusted Odd ratio: 0.11, 95% Confidence interval (0.03–0.48), p-value = 0.003] were less likely to be exposed to HAP when compared with households with a household head having no education. Conclusions This study revealed that most households in Uganda have exposure to household air pollution caused by the type of cooking fuel used in the household. This underscores the need for innovations in cooking fuels like clean energy stoves that are cost-effective and cause less exposure to household air pollution.
