Community effectiveness of stove and health education interventions for reducing exposure to indoor air pollution from solid fuels in four Chinese provinces

<p>In addition to many recent actions taken to reduce emissions from energy production, industry, and transportation, a new campaign substituting residential solid fuels with electricity or natural gas has been launched in Beijing, Tianjin, and other 26 municipalities in northern China, aiming at solving severe ambient air pollution in the region. Quantitative analysis shows that the campaign can accelerate residential energy transition significantly, and if the planned target can be achieved, more than 60% of households are projected to remove solid fuels by 2021, compared with less than 20% without the campaign. Emissions of major air pollutants will be reduced substantially. With 60% substitution realized, emission of primary PM2.5 and contribution to ambient PM2.5 concentration in 2021 are projected to be 30% and 41% of those without the campaign. With 60% substitution, average indoor PM2.5 concentrations in living rooms in winter are projected to be reduced from 209 (190-230) &#956;g/m3 to 125 (99-150) &#956;g/m3. The population-weighted PM2.5 concentrations can be reduced from 140 &#956;g/m3 in 2014 to 78 &#956;g/m3 or 61 &#956;g/m3 in 2021 given that 60% or 100% substitution can be accomplished. Although the original focus of the campaign was to address ambient air quality, exposure reduction comes more from improved indoor air quality because approximately 90% of daily exposure of the population is attributable to indoor air pollution. Women benefit more than men.</p>

Indoor Air Pollution (IAP) has become a major concern in India in recent years because women and young children are highly exposed to smoke of various types of unclean fuels used for cooking and heating in the household result into risk of respiratory disorders among them. The paper aims to seek association between prevalence of acute respiratory infection (ARI) among children less than five years of age and use of cooking fuels in households of India. The analysis is based on 52,868 Children less than five years of age included in India's third National Family Health Survey conducted in 2005-2006. Effects of exposure to cooking smoke, determined by the type of fuel used for cooking such as biomass and solid fuels versus cleaner fuels, on the reported prevalence of ARI were estimated using multivariate logistic regression. Since the effects of cooking smoke are likely to be confounded with effects of tobacco smoking, age, and other such factors, the analysis was carried out after statistically controlling for such factors. The results indicate that Children under five years of age living in households using biomass and solid fuels have a significantly higher risk of ARI than those living in households using cleaner fuels (OR: 1.54; 95%CI: 1.38-1.72; p = .010). The findings have important program and policy implications for countries such as India, where large proportions of the population still rely on polluting biomass fuels for cooking and heating. Decreasing household biomass and solid fuel use and increasing use of improved stove technology may decrease the health effects of indoor air pollution. More epidemiological research with better measures of smoke exposure and clinical measures of ARI is needed to validate the findings.

Background. More than 90% of all low birthweight (LBW) babies are born in developing countries, and half of the population in developing nations uses solid fuels as their primary source of energy for cooking. An association between household use of solid biomass fuels and reduced newborn weight has been found in a number of countries. Bangladesh has a high prevalence of LBW babies (22%), and 88% of the population use solid fuels for cooking. Objectives. This study aims to explore whether indoor air pollution is associated with LBW in Bangladesh, an important determinant of infant mortality and morbidity. Methods. The 2011 Bangladesh Demographic and Health Survey (BDHS) was used for the present analysis. The total number of births reported in the previous five years by respondents in the survey sample was 8,753. Mothers' recall of their baby's weight was the dependent dichotomous variable. A mixed effects logistic regression model was fitted using region as a random effect and several independent fixed effects. Results. High pollutant cooking fuels, such as coal and wood, resulted in higher odds of having a LBW child compared to use of electricity/gas (odds ratio (OR): 2.6, confidence interval (CI): 1.1–6.2 and OR: 1.1, CI: 1.0–1.2). Factors which lowered the odds include mothers with a bachelor's degree or higher education (OR: 0.6, CI: 0.4–0.9), third order children (OR: 0.8, CI: 0.6–0.9), fourth or higher order children (OR: 0.8, CI: 0.6–1.0), having a male child (OR: 0.7, CI: 0.7–0.8), and receiving sufficient antenatal care (OR: 0.8, CI: 0.6–0.9). Factors which increase the odds of having a LBW infant include mothers who are underweight compared to normal weight mothers (OR: 1.1, CI: 1.1–1.2), mistimed pregnancies (OR: 1.2, CI: 1.0–1.4), or unplanned pregnancies (OR: 1.3, CI: 1.0–1.7), compared to planned pregnancies. Conclusions. This is the first paper to show an association between use of highly pollutant biomass fuel and prevalence of LBW babies in Bangladesh, suggesting that besides polluting the air and causing respiratory illnesses, biomass fuel combustion may also affect the health of fetuses in utero. Further longitudinal studies are required to establish this finding among mothers in developing countries.
