“…Obesity in children is associated with reduced levels of physical activity and sports participation [21,49]. Our finding of a moderate association between BMI-Z scores and PACER scores such that increasing BMI-Z scores are associated with decreasing physical fitness score is consistent with the lower levels of activity in this population [39].…”

Background Childhood obesity is associated with reduced quality of life, physical fitness, and a higher prevalence of lower extremity (LE) pain; however, it is unclear whether and how these factors are related. Questions/purposes For this study we asked if obese children with LE pain (LE+) had higher BMI-Z scores, lower physical function and psychosocial health, and lower physical fitness compared with obese children without LE pain (LEÀ). We determined the association of BMI-Z score with physical function, psychosocial health, or physical fitness in obese children.

“…The risk factors related to the Westernised lifestyle that led to an increase in cases of obesity and asthma could also have led to the increase in the number of obese asthmatics. There are a number of common factors observed to be promoting both conditions, such as sedentary lifestyle (71,72) , dietary changes (73)(74)(75)(76)(77) , vitamin D insufficiency due to lower exposure to sunlight (78)(79)(80)(81) and tobacco exposure (82)(83)(84) , amongst others. Westernised lifestyle increased exposure to risk factors common to these conditions and contributed to the increase in obese children's development of asthma symptoms, as well as their experiencing them more severely and finding less success in treatment (85)(86)(87)(88)(89)(90) .…”

Association between obesity and asthma – epidemiology, pathophysiology and clinical profile

Obesity is a risk factor for asthma, and obese asthmatics have lower disease control and increased symptom severity. Several putative links have been proposed, including genetics, mechanical restriction of the chest and the intake of corticosteroids. The most consistent evidence, however, comes from studies of cytokines produced by the adipose tissue called adipokines. Adipokine imbalance is associated with both proinflammatory status and asthma. Although reverse causation has been proposed, it is now acknowledged that obesity precedes asthma symptoms. Nevertheless, prenatal origins of both conditions complicate the search for causality. There is a confirmed role of neuro-immune cross-talk mediating obesityinduced asthma, with leptin playing a key role in these processes. Obesity-induced asthma is now considered a distinct asthma phenotype. In fact, it is one of the most important determinants of asthma phenotypes. Two main subphenotypes have been distinguished. The first phenotype, which affects adult women, is characterised by later onset and is more likely to be non-atopic. The childhood obesity-induced asthma phenotype is characterised by primary and predominantly atopic asthma. In obesity-induced asthma, the immune responses are shifted towards T helper (Th) 1 polarisation rather than the typical atopic Th2 immunological profile. Moreover, obese asthmatics might respond differently to environmental triggers. The high cost of treatment of obesity-related asthma, and the burden it causes for the patients and their families call for urgent intervention. Phenotype-specific approaches seem to be crucial for the success of prevention and treatment.

Objective:To assess the effects of obesity on lung volume and capacity in children and adolescents.Data source:This is a systematic review, carried out in Pubmed, Lilacs, Scielo and PEDro databases, using the following Keywords: Plethysmography; Whole Body OR Lung Volume Measurements OR Total Lung Capacity OR Functional Residual Capacity OR Residual Volume AND Obesity. Observational studies or clinical trials that assessed the effects of obesity on lung volume and capacity in children and adolescents (0-18 years) without any other associated disease; in English; Portuguese and Spanish languages were selected. Methodological quality was assessed by the Agency for Healthcare Research and Quality.Data synthesis:Of the 1,030 articles, only four were included in the review. The studies amounted to 548 participants, predominantly males, with sample size ranging from 45 to 327 individuals. 100% of the studies evaluated nutritional status through BMI (z-score) and 50.0% reported the data on abdominal circumference. All demonstrated that obesity causes negative effects on lung volume and capacity, causing a reduction mainly in functional residual capacity in 75.0% of the studies; in the expiratory reserve volume in 50.0% and in the residual volume in 25.0%. The methodological quality ranged from moderate to high, with 75.0% of the studies classified as having high methodological quality.Conclusions:Obesity causes deleterious effects on lung volume and capacity in children and adolescents, mainly by reducing functional residual capacity, expiratory reserve volume and residual volume.
