Abstract
Asthma is a chronic condition that affects children worldwide. Accumulating number of studies reported that the prevalence of pediatric obesity and asthma might be altered through breastfeeding. It has been proposed that Leptin, which exists in human milk, is oppositely associated with weight increase in newborns. It may also influence peripheral immune system by promoting TH1 responses and suppressing TH2 cytokines. Leptin influences body weight and immune responses through complex signaling pathways at molecular level. Although previous studies provide explanations for the protective role of breastfeeding against both obesity and asthma, other factors such as duration of breastfeeding, parental, and prenatal factors may confound this relationship which requires further research.

Abstract
OBJECTIVE To examine associations between neighborhood characteristics and asthma prevalence and severity among low-income children in a large nationally representative sample. METHODS Data source: 2018 National Survey of Children's Health, limited to low-income children, ages 0-17 years. We grouped parent responses about neighborhood characteristics into 5 scores: neighborhood support, safety, resources and quality, and a total score. Logistic regression compared rates and severity of asthma by neighborhood scores, adjusting for age, sex, race, and income. RESULTS Of 8,653 low-income children, those living in neighborhoods with better total neighborhood scores were significantly less likely to have parent-reported asthma; OR = 0.9, 95% CI: 0.8-1.0; P = .02, with similar findings for children living in neighborhoods with higher support, safety, and quality scores. We found no associations between neighborhood scores and asthma severity in this population. CONCLUSIONS Favorable neighborhoods are associated with lower parent-reported asthma prevalence in low-income children but not asthma severity. These data may support providers and policy makers interested in child asthma in addressing neighborhood improvement.

Abstract
For centuries, regular exercise has been acknowledged as a potent stimulus to promote, maintain, and restore healthy functioning of nearly every physiological system of the human body. With advancing understanding of the complexity of human physiology, continually evolving methodological possibilities, and an increasingly dire public health situation, the study of exercise as a preventative or therapeutic treatment has never been more interdisciplinary, or more impactful. During the early stages of the NIH Common Fund Molecular Transducers of Physical Activity Consortium (MoTrPAC) Initiative, the field is well-positioned to build substantially upon the existing understanding of the mechanisms underlying benefits associated with exercise. Thus, we present a comprehensive body of the knowledge detailing the current literature basis surrounding the molecular adaptations to exercise in humans to provide a view of the state of the field at this critical juncture, as well as a resource for scientists bringing external expertise to the field of exercise physiology. In reviewing current literature related to molecular and cellular processes underlying exercise-induced benefits and adaptations, we also draw attention to existing knowledge gaps warranting continued research effort. © 2021 American Physiological Society.

Abstract
Regular physical activity not only improves general health but also can positively impact asthma outcomes, such as control and quality of life. Despite this, many asthma patients do not engage in regular physical activity because they mistakenly believe that they should restrict exercise participation. Health care providers have an opportunity to influence the physical activity levels of their patients during regular office visits. Nonetheless, health care providers often overlook physical activity counseling as an adjunct to pharmacological therapy in asthma patients, and in particular, overlook physical activity counseling. Some providers who acknowledge the benefits of physical activity report being unaware how to approach a conversation with patients about this topic. To address these issues, members of the Sports, Exercise, and Fitness Committee of the American Academy of Allergy, Asthma, and Immunology (AAAAI) performed a focused literature search to identify and evaluate the effects of physical activity in patients with asthma. The purpose of this report is to summarize the evidence for physical activity's impact on asthma patients' disease control, pulmonary function, and overall well-being. Several subpopulations of patients with asthma, including children, adolescents, and older adults, are considered individually. In addition, this report offers practical recommendations for clinicians, including how to identify and overcome barriers to counseling, and methods to incorporate physical activity counseling into asthma treatment practice.

Abstract
The prevalence of asthma remains high worldwide, with increasing awareness of the morbidity and mortality from asthma in low-income countries. In the UK, despite the development of biological treatments, many patients remain suboptimally controlled, and mortality rates have been static for decades. Therefore, new approaches are needed to treat asthma that are scalable at minimal cost. Exercise immunology is an expanding field, and there is growing evidence that exercise can modulate inflammatory and immune processes in asthma. Whilst exercise is encouraged in current treatment guidelines, there are no specific recommendations as to the intensity, frequency or duration of exercise exposure. Despite national and international guidance to increase exercise, patients with asthma are less likely to engage in physical activity. This review explores the disease modifying benefit of exercise in asthma. We also review the domains in which exercise exerts positive clinical effects in asthma, including the effects of exercise on symptom scores, quality of life, psychosocial health, and in the obese asthma phenotype. Finally, we review the barriers to exercise in asthma, given the benefits it confers. A better understanding of the mechanisms through which exercise exerts its positive effects in asthma may provide more accurate prescription of exercise training programmes as part of broader asthma management, with the potential of identification of new drug targets.

Abstract
Adverse childhood experiences (ACEs) are stressful or traumatic events that children experience before age 18 years. Studies have linked exposure to ACEs and negative health, and developmental and behavioral outcomes. Screening in pediatric medical settings provides a clear opportunity for early detection, intervention, and treatment. Providing anticipatory guidance on healthy relationships, sleep, exercise, nutrition, mindfulness, and nature is essential. Pediatric medical providers must screen and intervene. Primary care is the ideal setting for ACE screening because interacting with children and their families at regular intervals can allow patients and providers to develop a trusting relationship.

Abstract
PURPOSE OF REVIEW The purpose of this review is to discuss the most recent studies on lifestyle interventions in pediatric asthma. We include studies on physical activity and exercise, sedentary time, nutrition, behavioral therapy and the role of schools. RECENT FINDINGS Several small studies in children with asthma suggest that exercise interventions can improve aerobic fitness, asthma symptoms or control and quality of life. Existing evidence supports recommending higher intake of fruits and vegetables for asthma risk and control. In contrast, the 'Western diet' - high in refined grains, highly processed foods, red meats and fried foods with low intake of fruits and vegetables - has a proinflammatory effect and may alter microbiota composition leading to worse asthma outcomes. Finally, there are opportunities to utilize schools to promote physical activity, though standardization of asthma management in the schools is needed. SUMMARY Assessing physical activity/fitness levels, sedentary time and nutritional status is important in the management of children with asthma, as they are modifiable factors. Larger rigorous studies evaluating lifestyle interventions are needed to better inform current asthma guidelines as well as to understand the underlying mechanism(s) related to physical activity and diet in asthma.

Abstract
Introduction: Obesity affects about 40% of US adults and 18% of children. Its impact on the pulmonary system is best described for asthma. Areas covered: We reviewed the literature on PubMed and Google Scholar databases and summarize the effect of obesity, its associated metabolic dysregulation and altered systemic immune responses, and that of weight gain and loss on pulmonary mechanics, asthma inception, and disease burden. We include a distinct approach for diagnosing and managing the disease, including pulmonary function deficits inherent to obesity-related asthma, in light of its poor response to current asthma medications. Expert opinion: Given the projected increase in obesity, obesity-related asthma needs to be addressed now. Research on the contribution of metabolic abnormalities and systemic immune responses, intricately linked with truncal adiposity, and that of lack of atopy, to asthma disease burden, and pulmonary function deficits among obese children is fairly consistent. Since current asthma medications are more effective for atopic asthma, investigation for atopy will guide management by distinguishing asthma responsive to current medications from the non-responsive disease. Future research is needed to elucidate mechanisms by which obesity-mediated metabolic abnormalities and immune responses cause medication non-responsive asthma, which will inform repurposing of medications and drug discovery.

Abstract
Background: There is a clear relationship between obesity and asthma, with obesity recognized as a risk factor for asthma. There is mounting evidence, however, that asthma may predict obesity risk via behavioral pathways. Objectives: The purpose of this study was to assess the cross-sectional relationships between asthma, body mass index (BMI) percentile, and behavioral factors including caloric intake, dietary inflammatory index, moderate-vigorous physical activity (MVPA), and sedentary time (SED) among African American adolescents. Methods: A community-based sample of 195 African American youth (ages 11-18 years) were included in this analysis. Asthma status was based on self-report using the International Study of Asthma and Allergies in Children's Phase Three questionnaire. MVPA and SED were measured via accelerometry, and caloric intake and dietary inflammatory index were evaluated with the Food Frequency Questionnaire. Weight status was assessed via BMI percentile using measured weight, height, and CDC growth charts. Results: Adolescents with a history of asthma were significantly more overweight (62% vs. 43%, p = 0.04) and consumed a higher inflammatory diet (1.6 ± 0.3 vs. 1.0 ± 0.2, p = 0.02) than their peers who never had asthma. After adjusting for all covariates, activity and dietary variables, odds ratio analysis revealed adolescents who reported ever having asthma were 3.1 ± 1.5 times as likely to be overweight or obese than adolescents with no asthma history (p = 0.02). Conclusions: Presence of asthma history was associated with increased obesity risk in African American adolescents, independent of behavioral factors. Longitudinal studies are needed to better understand the relationship between asthma and obesity in African American adolescents.

Abstract
Introduction: Fitness can improve asthma management. However, children from disadvantaged and minority communities generally engage less in physical activity, and have increased obesity and asthma disease burden. The goal of this pilot study is to evaluate (1) the feasibility of an exercise intervention program in a school-based setting (attendance and fitness improvement) and (2) the effect of the intervention on fitness, asthma, and clinical outcomes in normal weight and overweight/obese children with asthma from low-SES population. Materials and Methods: Nineteen children, ages 6-13 years, from two elementary schools in Santa Ana, CA, a population with high percentage of Hispanic and low socioeconomic status, participated. Training sessions occurred at the schools during afterschool hours (3 sessions weekly × 4 months) and included mainly aerobic age-appropriate activities/games and a small component of muscle strength. Before and after the intervention, evaluations included pulmonary function testing, cardiopulmonary exercise testing (peak V ˙ O2), assessments of habitual physical activity, body composition (DXA), asthma questionnaires, and blood (cardiometabolic risk factors). Results: Seventeen of 19 participants completed the study. Adherence to the program was 85%. Based on BMI %ile, 11 of the participants were overweight/obese and 8 were normal weight. Ten participants had persistent asthma and 9 children had intermittent asthma. Training was effective as peak V ˙ O2 improved significantly (8.1%, SD ± 10.1). There was no significant change in BMI %ile but a significant improvement in lean body mass (1%, SD ± 2.0) and decrease in body fat (1.9%, SD ± 4.6). Asthma quality of life outcomes improved following the intervention in symptoms, emotional function, and overall. There was no change in asthma control or pulmonary function. Five of 10 participants with persistent asthma decreased their maintenance medications. Lipid levels did not change except HDL levels increased (46.1 ± 8.4 mg/dL to 49.5 ± 10.4 mg/dL, p = 0.04). Discussion: A school-based exercise intervention program designed specifically for children with asthma for a predominantly economically disadvantaged and minority population was feasible with good adherence to the program and substantial engagement from the schools, families and participants. The exercise intervention was effective with improvement in aerobic fitness, body composition, asthma quality of life, and lipid outcomes, setting the stage for a larger multicenter trial designed to study exercise as an adjunct medicine in children with asthma.
