“…A possible limitation in this study was also the subjective measure of indoor exposures of potential allergens and chemical pollutants from cooking fuels, which was not corroborated with objective environmental measurements. However, our findings are similar to other studies that have used similar subjective assessments of indoor pollutants …”

“…However, the prevalence of doctor‐diagnosed asthma reported in this study is within the range of those reported in the global pediatric asthma prevalence surveys on African children with reported proportions from 2.5% in Ethiopia and Burkina Faso to almost 10% in Swaziland . The prevalence of doctor‐diagnosed asthma from recent cross‐sectional studies from other low‐ and middle‐income countries were as high as 7.5% in Iran, 6% in India, 4.8% in China, 3% in Senegal, 2.5% in Mongolia, to 2% in Georgia …”

Asthma‐related outcomes associated with indoor air pollutants among schoolchildren from four informal settlements in two municipalities in the Western Cape Province of South Africa

The health impact of indoor air pollution in informal settlement households has not been extensively studied in South Africa. This cross‐sectional study investigated the association between asthma and common indoor exposures among schoolchildren from four informal settlements located in two municipalities in the Western Cape Province. A total of 590 children, aged 9‐11 years, were recruited. The International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was administered to caregivers. Pulmonary function assessment included spirometry and fractional exhaled nitric oxide (FeNO). Phadiatop test for atopy was done. The prevalence of doctor‐diagnosed asthma was 3.4% (n = 20) among whom only 50% were on treatment. The prevalence of current wheeze was 12.9%, and 17.6% had airway obstruction (FEV1 < lower limit of normal), while 10.2% had airway inflammation (FeNO > 35 ppb). In adjusted logistic regression models, dampness, visible mold growth, paraffin use for cooking, and passive smoking were associated with a twofold to threefold increased risk in upper and lower airway outcomes. The strongest association was that of visible mold growth with rhinitis (adjusted odds ratio—aOR 3.37, 95% CI: 1.69‐6.71). Thus, there is a need for improved diagnosis of childhood asthma and Indoor Air Quality in informal settlement households.

“…In a cross‐sectional study conducted in rural Senegal (west Africa) from a total of 1513 children aged 6‐7 years, 130 (9%) reported wheezing within the last 12 months, and 41 (3%) had a clinical asthma diagnosis which were compatible with the results of the current study. Our results showed that the prevalence of wheezing within the last year was higher in 6‐ to 7‐year olds (7.8%) while lower prevalence was obtained in participants aged 13‐14 years (9.5%).…”

Background:The actual prevalence of paediatric asthma as a worldwide chronic disease has been surveyed in developed countries. However, no sufficient survey has been conducted in most of the eastern developing countries. Herein, we took measures to evaluate the prevalence of paediatric asthma in Iran. Methods: In this national cross-sectional study, the prevalence of asthma symptoms was estimated throughout the country using a randomized multistage stratified cluster sampling method in 16 410 and 16 850 individuals aged 6-7 and 13-14 years, respectively. A validated questionnaire including core questions of the International Study of Asthma and Allergies in Childhood (ISAAC) was applied between November 2015 and February 2016. Results: The total prevalence of asthma was 10.9% (n = 3624) (95% confidence interval [CI]: 10.6%-11.2%) which was significantly higher among 13-to 14-year olds compared to a younger age group (12.4% vs. 9.4%, P < 0.001), males versus females (12.1% vs. 9.8%, P < 0.001) and residents of urban compared to rural areas (P = 0.003). The prevalence of severe asthma was 3.9%, being significantly more prevalent in higher age groups and male individuals (P < 0.001). A significant relationship was found between asthma and passive smoking in both 6-to 7-and 13-to 14-year olds (P < 0.001). Conclusions: The prevalence of asthma and severe asthma in the paediatric population of Iran was similar to other developing countries. It is recommended to pay special attention to urban regions, male individuals and higher age groups for better controlling of asthma. Nevertheless, further national surveys are necessary to determine the trend of paediatric asthma in Iran.

“…However, depending on exposure to these stoves, opinions may have been based on a specific stove design rather than the broader category of ICS. Finally, in the context of a preceding survey asking questions about child respiratory symptoms related to smoke [ 21 ], participants may have been inclined to report dissatisfaction with their traditional open-fire stove and show enhanced interest in alternative technologies.…”

“…The largest villages were more consistently accessible during the rainy seasons and including them allowed our field workers to contact the greatest number of households within a defined geographic area. This survey was co-administered with a survey on asthma symptoms in children [ 21 ]. All households within each village with at least one child aged five through eight years old (the inclusion criteria for the asthma portion) were included.…”

Traditional cooking practices and preferences for stove features among women in rural Senegal: Informing improved cookstove design and interventions

Nearly half the world’s population burns solid fuel for cooking, heating, and lighting. The incomplete combustion of these fuels is associated with detrimental health and environmental effects. The design and distribution of improved cookstoves that increase combustion efficiency and reduce indoor air pollution are a global priority. However, promoting exclusive and sustainable use of the improved stoves has proved challenging. In 2012, we conducted a survey in a community in rural Senegal to describe stove ownership and preferences for different stove technologies. This report aims to describe local stove and fuel use, to identify household preferences related to stove features and function, and to elicit the community perceptions of cleaner-burning stove alternatives with a focus on liquid propane gas. Similar to many resource-limited settings, biomass fuel use was ubiquitous and multiple stoves were used, even when cleaner burning alternatives were available; less than 1% of households that owned a liquid propane stove used it as the primary cooking device. Despite nearly universal use of the traditional open fire (92% of households), women did not prefer this stove when presented with other options. Propane gas, solar, and improved cookstoves were all viewed as more desirable when compared to the traditional open fire, however first-hand experience and knowledge of these stoves was limited. The stove features of greatest value were, in order: large cooking capacity, minimal smoke production, and rapid heating. Despite the low desirability and smoke emisions from the traditional open fire, its pervasive use, even in the presence of alternative stove options, may be related to its ability to satisfy the practical needs of the surveyed cooks, namely large cooking capacity and rapid, intense heat generation. Our data suggest women in this community want alternative stove options that reduce smoke exposure, however currently available stoves, including liquid propane gas, do not address all of the cooks’ preferences.
