Indeed, increased airway and systemic ADMA is inversely associated with eNO [40] and in the SARP study population, with more frequent respiratory symptoms, poorer quality of asthma and lower lung function [34]. The primary aim of asthma management is to make an early diagnosis and to achieve a prompt control of symptoms, in order to reduce the risk of future exacerbations and progressive loss of lung function ().When asthma is correctly diagnosed, low-dose inhaled . Therefore, the extent by which greater BMI increases the likelihood of being diagnosed with asthma, independently of bias, remains unknown. http://prismstandard.org/namespaces/basic/2.0/ Am J Respir Crit Care Med.

For example, in a cross sectional study of the SARP study population, the relationship between BMI and duration of asthma (in years) varied with regard to whether the onset of asthma was early or late (before or after 12 years of age) [5]. Systematic reviews have shown benefit from weight-loss interventions on asthma outcomes, but the role of bariatric surgery is still unclear.

Springer Nature ORCID Schema 10.1186/s40733-015-0001-7 The response may depend on how it relates to additional phenotypical factors. However, this phenomenon may not necessarily reflect an absolute reduction of airway eosinophils in obesity, but rather, reduced migration into the airway lumen. orcid However, clinical characteristics associated with the highest BMI cluster that have been consistently described across studies include having late onset asthma, lower exhaled nitric oxide (eNO) levels, less airway eosinophils, and reduced atopy [8–10]. In a large study of 4,619 eligible participants in the Coronary Artery Risk Development in Young Adults (CARDIA) cohort followed over 25 years, MetSyn predicted asthma incidence in women, but this association was found to be mostly confounded by BMI [56].

The reduced steroid response in obese asthmatics could be secondary to increased resistance; as shown by Sutherland et al, who showed that being obese was associated with an in vitro blunted response to dexamethasone-induced mitogen-activated protein (MAP) kinase phosphatase-1 (MKP-1) and baseline tumor necrosis factor (TNF)-alpha in peripheral blood mononuclear cells (PBMCs) and bronchoalveolar lavage cells.

Ultimately, increased steroid resistance may explain why, even when adequately treated, asthmatics – regardless of severity - with a BMI > 25 are less likely to transition from an uncontrolled state to a controlled state over time [48]. An important confounder to the obese – asthma association is metabolic syndrome (MetSyn), which occurs in ~20 % of the general population and 60 % of obese subjects. This report is based on an exhaustive review of the published literature on the definitions, measurements, epidemiology, economics and interventions applied to nine chronic conditions and risk factors.

The mechanism justifying the higher prevalence of obesity related to asthma amongst boys is fairly unclear, but those sources reporting a stronger association amongst girls suggest similar explanations to those in adults, pointing at adipokine production (Reference Sood 39) and early menarche; this is caused by increased body mass associated . However, it remains to be determined whether obesity that antecedes or occurs after an asthma diagnosis impacts asthma severity or control any differently. An important question, which remains to be answered, is whether weight loss improves response to inhaled or systemic corticosteroids.
