[Stoves] NPJ publication: Effects and acceptability of implementing improved cookstoves and heaters to reduce household air pollution [including evaluation of ESMAP supported heating stove trial in Kyrgyzstan]

Sat Aug 17 11:48:01 CDT 2019

Dear Friends

This report documents the (very) positive result of the health impact on people living in homes in Kyrgyzstan that received a new high performance, low emissions heating and cooking stove, substituting for their traditional appliances.

Dear colleagues,

Hope you are having a great summer! I would like to draw your attention of a recent publication by npj│Primary Care Respiratory Medicine “Effects and acceptability of implementing improved cookstoves and heaters to reduce household air pollution: a FRESH AIR study”. The study includes an independent evaluation of ESMAP supported high efficiency low emission heating stove trial in Kyrgyzstan. I extract the findings on Kyrgyzstan as well as the abstract for your easy reference.

Trust it adds additional evidence on the linkages of access to clean cooking/heating solutions, household air pollution, and health as well as the importance on locally tailored implementation to improve acceptability and effectiveness.

Kyrgyzstan.  The daily  respiratory  symptoms among adults and children  decreased;  breathlessness  among  adults  and  both breathlessness  and  wheeze  among  children disappeared. Symptoms  during  cooking disappeared in almost all cases, both in adults and children. The CCQ and MRC score reduced by 93 and 23% respectively. The number of chest infections decreased considerably for both adults and children. The number of missed days at school decreased by 72%. All changes in Kyrgyzstan between the baseline and second post intervention measurement were statistically significant (p< 0.05).

Abstract: The objective was to evaluate the effectiveness and acceptability of locally tailored implementation of improved cookstoves/heaters in low- and middle-income countries. This interventional implementation study among 649 adults and children living in rural communities in Uganda, Vietnam and Kyrgyzstan, was performed after situational analyses and awareness programmes. Outcomes included household air pollution (PM2.5and CO), self-reported respiratory symptoms (with CCQ and MRC-breathlessness scale), chest infections, school absence and intervention acceptability. Measurements were conducted at baseline, 2 and 6–12 months after implementing improved cookstoves/heaters. Mean PM2.5values decrease by 31% (to 95.1 μg/m3) in Uganda (95%CI 71.5–126.6), by32% (to 31.1 μg/m3) in Vietnam (95%CI 24.5–39.5) and by 65% (to 32.4 μg/m3) in Kyrgyzstan (95%CI 25.7–40.8), but all remain above the WHO guidelines. CO-levels remain below the WHO guidelines. After intervention, symptoms and infections diminish significantly in Uganda and Kyrgyzstan, and to a smaller extent in Vietnam. Quantitative assessment indicates high acceptance of the new cookstoves/heaters. In conclusion, locally tailored implementation of improved cookstoves/heaters is acceptable and has considerable effects on respiratory symptoms and indoor pollution, yet mean PM2.5 levels remain above WHO recommendations.
