“…Fine particulates from cooking are not associated with gas cooking in particular, but with all heating of foods. Thus NO 2 and/or other unmeasured components from gas use could lead to inflammatory responses in the airways [28]. PEF and MEF75% indicate large airway dysfunction, but the variability is caused by effort and muscle strength.…”

“…Several studies found reduced respiratory health associated with gas stoves [3][4][5][6][7][8][9][10][11][12][13]. NO 2 emitted from gas stoves and ovens can increase exposure, especially in small kitchens with tight windows, to concentrations above the threshold limit value (protecting workers) and well above ambient air quality standards (protecting the general public).…”

Inconsistent effects of gas cooking on lung function have been reported. In a previous study from Austria, we demonstrated a significant, though small, reduction of lung function parameters in children living in homes with gas stoves. We used a larger international database to check if this finding can be generalised.To study the relative impact of cooking with gas on lung function parameters of primary school children in a wide range of geographical settings, we analysed flow and volume data of ,24,000 children (aged 6-12 yrs) from nine countries in Europe and North America.Exposure information was obtained by comparable questionnaires and spirometry according to an American Thoracic Society/European Respiratory Society protocol. Linear regressions were used, controlling for individual risk factors and study area. Heterogeneity between study-specific results and mean effects were estimated using meta-analytical tools.On average, gas cooking reduced lung function parameters. Overall effects were small (-0.1-0.7%) and only significant for forced vital capacity and forced expiratory volume in 1 s. There was some indication that allergic children were more affected by gas cooking.Under current housing conditions, gas cooking is associated with only small reductions in lung function.

“…Exposure to other ambient pollutants (particulate matter [85,86] nitrogen dioxide, gas cooking [87], sulphur dioxide, etc) is also associated with increased cough in children in both cross sectional [85,86] and longitudinal studies [88]. Indoor biomass combustion exposure also increases coughing illness associated with respiratory infections with an exposure-response effect [89].…”

Defining the Cough Spectrum and Reviewing the Evidence for Treating Non-Specific Cough in Children

Cough is the most common presenting symptom to medical practitioners to the USA and Australia. Worldwide, the desire to reduce the impact of the symptom of cough is reflected in the billions of dollars spent on over the counter cough medications. Easy to apply and clinically relevant definitions of cough are necessary for effective communication and to progress clinical research. Based on current data, pediatric cough definitions have been formulated on timeframe (acute and chronic), clinical cough characteristics (dry vs wet/productive and classical recognizable cough sounds) and suggestive broad underlying etiology categories (expected cough, specific cough, non-specific cough and protracted bronchitis). These definitions are distinct from adult definitions, as many of adult-type aspects of cough cannot be applied to young children. With the lack of pediatric data, adult data is often inappropriately extrapolated to children.In the second part of this paper, the evidence for and against the use of the various pharmaceuticals (such as OTC medications, antimicrobials, treatment for gastroesophageal reflux and asthma) for cough in children are reviewed. The utility of 'time to response' is important in the management of cough in children to minimize possible associated morbidity of the therapies for non-specific cough.

The aim of the environmental epidemiological study was to determine possible adverse effects on the health of children in the environmentally polluted areas of Bitterfeld and Hettstedt compared to the less polluted area of Zerbst (Eastern Germany). The changes of the health parameters were recorded together with the environmental changes during the time period of 6 years. The study design consisted of three repeated regional cross-sectional studies in 1992/93, 1995/96 and 1998/99. In total, 7,611 questionnaires could be analysed (participation rate: 89%, 75% and 75%). Children living in the most polluted area of Hettstedt had a noticeable higher risk for non-allergic respiratory diseases and symptoms compared to children living in the control area of Zerbst. From 1992 to 1999 a statistically significant decrease in the prevalences of these health outcomes was found. Children without indoor pollutants in their homes had the greatest benefit by the improvement of ambient air quality. The increase in lung function (FVC, FEV1) also underlines the improvement of the respiratory health. Children living in the polluted areas reported allergies more often (physician's diagnosis, allergy specific antibodies). The prevalence of asthma, the bronchial hyperreactivity and atopic eczema was increased within the observational period of 6 years. An increased prevalence was also shown for more severe allergic sensitisation (RAST classes> 17.5 kU/l), while the prevalence of hay fever increased slightly on a non-significant level. The burden with lead and cadmium was higher in children living in polluted areas and decreased during the study period except for 1997 where the lead concentration in blood increased according to the higher lead concentration in settled dust in Hettstedt at that time.
