children s respiratory health after an efficient Biomass Stove patsari intervention
Ecohealth, 2015Co-Authors: Astrid Schilmann, Horacio Riojasrodriguez, Karina Ramirezsedeno, Victor Berrueta, Rogelio Perezpadilla, Isabelle RomieuAbstract:Household use of fuelwood represents a socio-ecological condition with important health effects mainly in rural areas from developing countries. One approach to tackle this problem has been the introduction of efficient wood-burning chimney Stoves. The aim of this study was to assess the impact of the introduction of Patsari Stoves on the respiratory health of young children in highlands Michoacan, Mexico. A total of 668 households in six rural communities in a fuelwood using region were selected and randomized to receive an improved Stove (Patsari) or rely entirely on the traditional wood fire until the end of the follow-up including 10 monthly visits. Adherence to the intervention was variable over the follow-up time. The actual use of the Patsari Stove as reported by the mother showed a protective effect mainly on the upper and lower respiratory infection duration (IRR URI 0.79, 95% CI 0.70–0.89, and LRI 0.41, 95% CI 0.21–0.80) compared to households that used only an open fire. Fewer days of child’s ill health represents saved time for the woman and avoided disease treatment costs for the family, as well as a decrease in public health costs due to a reduction in the frequency of patient visits.

impact of the improved patsari Biomass Stove on urinary polycyclic aromatic hydrocarbon biomarkers and carbon monoxide exposures in rural mexican women
Environmental Health Perspectives, 2011Co-Authors: Horacio Riojasrodriguez, Astrid Schilmann, Adriana Teresa Marronmares, Omar Masera, Lovisa C Romanoff, Andreas Sjodin, Leonora Rojasbracho, Larry L Needham, Isabelle RomieuAbstract:Background: Cooking with Biomass fuels on open fires results in exposure to health-damaging pollutants such as carbon monoxide (CO), polycyclic aromatic hydrocarbons (PAHs), and particulate matter. Objective: We compared CO exposures and urinary PAH biomarkers pre- and postintervention with an improved Biomass Stove, the Patsari Stove. Methods: In a subsample of 63 women participating in a randomized controlled trial in central Mexico, we measured personal CO exposure for 8 hr during the day using continuous monitors and passive samplers. In addition, first-morning urine samples obtained the next day were analyzed for monohydroxylated PAH metabolites by gas chromatography/isotope dilution/high-resolution mass spectrometry. Exposure data were collected during the use of an open fire (preintervention) and after installation of the improved Stove (postintervention) for 47 women, enabling paired comparisons. Results: Median pre- and postintervention values were 4 and 1 ppm for continuous personal CO and 3 and 1 ppm for passive sampler CO, respectively. Postintervention measurements indicated an average reduction of 42% for hydroxylated metabolites of naphthalene, fluorene, phenanthrene, and pyrene on a whole-weight concentration basis (micrograms per liter of urine), and a 34% reduction on a creatinine-adjusted basis (micrograms per gram of creatinine). Pre- and postintervention geometric mean values for 1-hydroxypyrene were 3.2 and 2.0 μg/g creatinine, respectively. Conclusion: Use of the Patsari Stove significantly reduced CO and PAH exposures in women. However, levels of many PAH biomarkers remained higher than those reported among smokers.

improved Biomass Stove intervention in rural mexico impact on the respiratory health of women
American Journal of Respiratory and Critical Care Medicine, 2009Co-Authors: Isabelle Romieu, Horacio Riojasrodriguez, Astrid Schilmann, Adriana Teresa Marronmares, Rogelio Perezpadilla, Omar MaseraAbstract:Rationale: Exposure to Biomass smoke has been related to adverse health effects. In Mexico, one household in four still cooks with Biomass fuel, but there has been no evaluation of the health impact of reducing indoor air pollution. Objectives: To evaluate the health impact of the introduction of an improved BiomassStove (Patsari; Interdisciplinary Groupfor Appro- priate Rural Technology (GIRA), Patzcuaro, Mexico) in Mexican women. Methods:ArandomizedcontrolledtrialwasconductedintheCentral Mexican state of Michoacan. Households were randomized to re- ceive the Patsari Stove or keep their traditional open fire. A total of 552 women were followed with monthly visits over 10 months to assessStoveuse,inquireaboutrespiratoryandothersymptoms,and obtain lung function measurements. Statistical analysis was con- ducted using longitudinal models. Measurements and Main Results: Adherence to the intervention was low(50%).WomenwhoreportedusingthePatsariStovemostofthe timecomparedwiththoseusingtheopenfirehadsignificantlylower riskofrespiratorysymptoms(relativerisk(RR),0.77;95%confidence interval(CI),0.62-0.95forcoughandRR,0.29;95%CI,0.11-0.77for wheezing) adjusted for confounders. Similar results were found for otherrespiratorysymptomsas wellas for eyediscomfort, headache, and back pain. Actual use of the Patsari Stove was associated with alowerFEV1decline(31ml)comparedwiththeopenfireuse(62ml) over 1 year of follow-up (P 5 0.012) for women 20 years of age and older, adjusting for confounders. Conclusions: The use of the Patsari Stove was significantly associated with a reduction of symptoms and of lung function decline compa- rable to smoking cessation.

performance testing for monitoring improved Biomass Stove interventions experiences of the household energy and health project
Energy for Sustainable Development, 2007Co-Authors: Robert Bailis, Omar Masera, Victor Berrueta, Chaya Chengappa, Karabi Dutta, Rufus Edwards, Dean Still, Kirk R SmithAbstract:This paper describes the monitoring and evaluation of three improved cookStove dissemination projects implemented between 2004 and 2006 by non-governmental organizations (NGOs) in India and Mexico. The projects assessed Stove performance using lab-based water boiling tests (WBTs), which yield a number of performance indicators including time to boil water, specific fuel consumption, and energy efficiency when the Stove is operated at both high and low power output. They also conducted field-based kitchen performance tests (KPTs), which yield daily per capita fuel consumption in real cooking conditions. In addition, one NGO utilized a controlled cooking test, which combined elements of lab- and field-based tests. In all cases, improved cookStoves (ICSs) were compared to local traditional cookStoves (TCSs). The results of the WBTs were mixed. Although the improved Stoves generally showed some improvement in efficiency for the low-power simmering phases, the Stoves were less efficient than traditional Stoves in high-power water-boiling phases. The results from the KPTs were much less ambiguous. Three ICS models were tested for fuel consumption during real household use. All ICSs showed statistically significant reductions (p < 0.05) in average daily per capita fuel use ranging from 19 to 67 %. We also explore the correlations between the outcomes in lab-based tests and field-based tests in order to understand the relationships between the two assessment methods. Only fuel consumption in the low-power phase of the WBT showed a strong correlation with fuel consumption in the field (r 2 = 0.83, p = 0.01). We discuss the implications of this association as well as the other outcomes and present some policy recommendations for monitoring and evaluation of large-scale Stove interventions.
