Symptoms of sleep apnea are markedly increased in children exposed to smoke from biomass fuels and are reduced by kitchen stoves that improved indoor biomass pollution. However, the impact of adherence to the use improved stoves has not been critically examined.
Sleep-related symptom questionnaires were obtained from children <15 years of age in 56 families residing in the communities of Lliupapuquio, Andahuaylas province in Peru before and 2 years after installation of less-polluting Inkawasi cooking stoves.
82 children with a lifetime exposures to indoor fuel pollution were included. When compared to those alternating between both types of stoves or those using traditional stoves only, those children who exclusively used Inkawasi cooking stoves showed significant improvements in sleep and respiratory related symptoms, but some minor albeit significant improvements occurred when both stoves were concomitantly used.
Improvements in respiratory and sleep-related symptoms associated with elevated indoor biomass pollution occur only following implementation and exclusive utilization of improved kitchen stoves.

    • "A major study of this intervention in Guatemala found that using clean stoves was associated with a 30% reduction in severe pneumonia among children younger than 18 months of age (Smith et al. 2011). A study in Peru found that using the new cookstoves significantly reduced sleep and respiratory symptoms in children 2 to 14 years of age, but only in households that used the less-polluting stoves exclusively and with adequate maintenance (Accinelli et al. 2014).

    ABSTRACT: Chronic diseases are increasing among children in Latin America. To examine environmental risk factors for chronic disease in Latin American children and to develop a strategic initiative for control of these exposures, the World Health Organization (WHO) including the Pan American Health Organization (PAHO), the Collegium Ramazzini, and Latin American scientists reviewed regional and relevant global data. Industrial development and urbanization are proceeding rapidly in Latin America and environmental pollution has become widespread. Environmental threats to children's health include traditional hazards such as indoor air pollution and drinking water contamination; as well as the newer hazards of urban air pollution; toxic chemicals such as lead, asbestos, mercury, arsenic, and pesticides; hazardous and electronic waste; and climate change. The mix of traditional and modern hazards varies greatly across and within countries reflecting industrialization, urbanization and socioeconomic forces. To control environmental threats to children's health in Latin America, WHO, including PAHO will focus on the most highly prevalent and serious hazards - indoor and outdoor air pollution, water pollution, and toxic chemicals. Strategies for controlling these hazards include developing tracking data on regional trends in children's environmental health (CEH); building a network of Collaborating Centres; promoting biomedical research in CEH; building regional capacity; supporting development of evidence-based prevention policies; studying the economic costs of chronic diseases in children; and developing platforms for dialogue with relevant stakeholders.

    ABSTRACT: Previous studies have uncovered a very high prevalence of sleep disorders in general, and of sleep-disordered breathing in particular among children exposed to indoor biomass fuel pollution. However, despite the significant symptomatology, parents are unlikely to report these issues during health-care visits. The objective of this study was to determine whether reduced caregiver perception of sleep disorders may account for the infrequent diagnosis and treatment of such problems in children residing at high altitudes and exposed to high biomass pollution. Parents of children aged 9-15 years of three communities residing in the Pasco region in Peru located between 3800 and 4200 meters above sea level were surveyed using a validated questionnaire instrument focused on symptoms associated with sleep-disordered breathing as well as whether caregivers perceived that their child suffered from a sleep disorder. Among the 77 children included, 48.1% had nocturnal awakenings and 46.8% had repetitive movements and restless sleep. Habitual snoring was present in 33.8% of all children. However, only 10.4% of mothers considered that their children had sleep problems, and all of their children had positive answers for ≥4 sleep symptoms. Children residing at high altitudes and exposed to traditional biomass-fueled stoves exhibit an extremely high frequency of sleep symptoms that are misperceived by their mothers as being "normal." Interventions aimed at increasing parental recognition and awareness of sleep problems will be essential to foster improved diagnosis and treatment. Copyright © 2015 Elsevier B.V.

    ABSTRACT: Household air pollution (HAP) resulting from the use of solid fuels presents a major public health hazard. Improved stoves have been offered as a potential tool to reduce exposure to HAP and improve health outcomes. Systematic information on stove interventions is limited. We conducted a systematic review of the current evidence of improved stove interventions aimed at reducing HAP in real life settings. An extensive search of ten databases commenced in April 2014. In addition, we searched clinical trial registers and websites for unpublished studies and grey literature. Studies were included if they reported on an improved stove intervention aimed at reducing HAP resulting from solid fuel use in a low or middle-income country. The review identified 5,243 records. Of these, 258 abstracts and 57 full texts were reviewed and 36 studies identified which met the inclusion criteria. When well-designed, implemented and monitored, stove interventions can have positive effects. However, the impacts are unlikely to reduce pollutant levels to World Health Organization recommended levels. Additionally, many participants in the included studies continued to use traditional stoves either instead of, or in additional to, new improved options. Current evidence suggests improved stove interventions can reduce exposure to HAP resulting from solid fuel smoke. Studies with longer follow-up periods are required to assess if pollutant reductions reported in the current literature are sustained over time. Adoption of new technologies is challenging and interventions must be tailored to the needs and preferences of the households of interest. Future studies require greater process evaluation to improve knowledge of implementation barriers and facilitators. The review was registered on Prospero (registration number CRD42014009796 ).
