“…Regarding meteorological factors, Tosca's study found a positive association between emergency calls for asthma exacerbation in children, wind speed, and amount of rainfall [27]. In our study, ambient temperature was a risk factor for asthma-related emergency room visits.…”

“…This meant that exposure levels for cases and controls were similar. In other studies, emergency calls for asthma exacerbation were significantly correlated with pollen exposure between April and August [27].…”

“…In recent decades, several epidemiological studies reported an association between short-term exposure to air pollution and adverse health effects, showing an increase in emergency room visits or hospital admissions as a result of increased pollution levels [1,7,8,26,27]. In a recent review, all 25 included studies reported an association between outdoor air pollution and asthma incidence in children [28].…”

“…It has been shown that average rates of pollutants (PM 10 , ozone, nitrogen dioxide, carbon monoxide, and benzene) vary; similarly, rates of nasal eosinophils, values for the fraction of exhaled nitric oxide, and peak flow charts have been found to vary over a week in asthmatic children [23]. However, few epidemiological studies take into account confounding factors such as meteorological conditions, viral infections, and pollen counts according to place of residence [6,14,27]. For a decade, no French study has evaluated the impact of pollution on asthmatic disease, despite the lowering of the WHOrecommended threshold values.…”

C h i l d r e n 's a s t h m a i s m u l t i f a c t o r i a l . Environmental factors like air pollution exposure, meteorological conditions, allergens, and viral infections are strongly implicated. However, place of residence has rarely been investigated in connection with these factors. The primary aim of our study was to measure the impact of particulate matter (PM), assessed close to the children's homes, on asthma-related pediatric emergency hospital visits within the Bouches-du-Rhône area in 2013. In a nested case-control study on 3-to 18-year-old children, each control was randomly matched on the emergency room visit day, regardless of hospital. Each asthmatic child was compared to 15 controls. PM 10 and PM 2.5 , meteorological conditions, pollens, and viral data were linked to ZIP code and analyzed by purpose of emergency visit. A total of 68,897 visits were recorded in children, 1182 concerning asthma. Short-term exposure to PM 10 measured near children's homes was associated with excess risk of asthma emergency visits (adjusted odds ratio 1.02 (95% CI 1.01-1.04; p = 0.02)). Male gender, young age, and temperature were other risk factors. Conversely, wind speed was a protective factor. Conclusion: PM 10 and certain meteorological conditions near children's homes increased the risk of emergency asthma-related hospital visits in 3-to 18-year-old children in Bouches-du-Rhône. What is Known:• A relationship between short-term exposure to air pollution and increase in emergency room visits or hospital admissions as a result of increased pollution levels has already been demonstrated. What is New:• This study confirms these results but took into account confounding factors (viral data, pollens, and meteorological conditions) and is based on estimated pollution levels assessed close to the children's homes, rather than those recorded at the hospital.• The study area, the Mediterranean, is favorable to creation of secondary pollutants in these sunny and dry seasons.

“…Significant associations have been identified between springtime pollen concentrations and emergency calls for asthma exacerbations among children [183]. Furthermore, an increase in the concentration of Ambrosia pollen by 10 grains/m 3 may increase hospital admissions for respiratory disorders by 25% [184].…”

Abstract:The evidence of observed health effects as well as projections of future health risks from climate variability and climate change is growing. This article summarizes new knowledge on these health risks generated since the IPCC fourth assessment report (AR4) was published in 2007, with a specific focus on the 53 countries comprising the WHO European Region. Many studies on the effects of weather, climate variability, and climate change on health in the European Region have been published since 2007, increasing the level of certainty with regard to already known health threats. Exposures to temperature extremes, floods, storms, and wildfires have effects on cardiovascular and respiratory health. Climate-and weather-related health risks from worsening food and water safety and security, poor air quality, and ultraviolet radiation exposure as well as increasing allergic diseases, vector-and rodent-borne diseases, and other climate-sensitive health outcomes also warrant attention and policy action to protect human health.

Over 2 million children in the US have uncontrolled asthma. African American children are disproportionately affected with a risk of dying from asthma that is 7.6 times higher than non-Hispanic White children. Racial disparities in childhood asthma are partially attributed to differential exposures to poverty; unsafe and stressful neighborhoods; and unhealthy physical environments. This paper describes the protocol for an ongoing National Institutes of Health/National Institute of Nursing Research-funded descriptive, cross-sectional study to investigate two neighborhood factors that may influence children's asthma. Building on an existing dataset, this study examines associations among neighborhood greenspace, neighborhood safety, and level of asthma control while controlling for indoor asthma triggers in an urban sample of predominantly low-income, African American children with persistent asthma. Two new variables are added to the dataset: availability of neighborhood greenspace and neighborhood violent crime rate. Greenspace is being accessed using geographic information systems and measured using the normalized difference vegetation index. Neighborhood violent crime rate is calculated using geocoded, point locations for crimes downloaded from the city police department. It is hypothesized that parents living in unsafe neighborhoods are likely to keep their children indoors, thereby increasing their children's exposure to indoor asthma triggers and limiting the potential benefits of neighborhood greenspace. The biggest challenges thus far are related to limited variability in greenspace and violent crime rates. Progress to date and strategies to address these challenges are discussed. Results have the potential to inform interventions to improve asthmatic children's health and influence public health policy.
