Prevalence of obesity in asthma and its relations with asthma severity and control

Childhood obesity in relation to poor asthma control and exacerbation: a meta-analysis

“…We excluded studies that had different measurement of exposure and outcomes because we intended to reduce heterogeneity as much as possible. A statistically significant higher risk of asthma severity in obese compared with non-obese children was reported by five excluded studies [31,32,34,36,37]. The other four excluded studies [13,33,35,56] showed no significant association between obesity and asthma control.…”

“…Low-quality studies (criteria for this exclusion are explained in the quality assessment section) were excluded from this meta-analysis. Studies that evaluated adolescents and adults without showing separate results [30,31] or studies that used other measurements of outcomes (e.g. missing schools due to wheezing and wheezing with exercise) [13,18,[32][33][34][35][36][37] were also excluded.…”

Atopic dermatitis is more severe in children over the age of two who have an increased body mass index

“…Obese children are more likely to develop atopic diseases such as atopic dermatitis and asthma , and up to 70% of children with atopic dermatitis may develop subsequent atopic diseases in the phenomenon known as the atopic march . While obesity is associated with an increased risk for atopic diseases such as atopic asthma, there has been conflicting evidence of whether or not obesity is related to a more severe disease . Likewise, obesity has been reported to correlate with more severe atopic dermatitis, although this was determined by parents' subjective rating of their child's atopic dermatitis as mild, moderate or severe in a questionnaire .…”

Long-term effect of weight loss induced by bariatric surgery on asthma control and health related quality of life in asthmatic patients with severe obesity: A pilot study

“…Obesity is a global problem, with several effects on the respiratory system, predisposing to serious respiratory diseases, including asthma [1]. Several epidemiological studies have reported the association between obesity and asthma [2e4], indicating an increase in asthma severity and exacerbation [5e7], therefore burdening patient's quality of life [8] and asthma control [9,10]. Recently, the respiratory metabolic phenotype (also called "metabotype") of obese asthmatic patients has been investigated by metabolomics [11,12].…”
