Summary
Urban children with asthma who are overweight engage in less physical activity. Weight and environmental factors influence this relationship, highlighting areas for future interventions.
Area of Science:
- Pediatric respiratory health
- Childhood obesity and physical activity
Background:
- Asthma and obesity are prevalent in urban minority children.
- Lower physical activity levels are a risk for urban children with asthma, contributing to obesity.
Purpose of the Study:
- To examine the association between lung function and moderate to vigorous physical activity (MVPA) in children with asthma.
- To identify moderators of this association, including weight and cultural/contextual factors.
Main Methods:
- A longitudinal study of 142 urban children (ages 7-9) with persistent asthma.
- Longitudinal mixed-effects models analyzed daily asthma status and physical activity, assessing moderating effects of weight and cultural/contextual factors.
Main Results:
- Average daily MVPA was below recommended guidelines, with variations by race/ethnicity and weight.
- Poorer asthma status correlated with lower MVPA in specific racial/ethnic groups and normal-weight children.
- Body Mass Index (BMI) moderated the asthma-MVPA association; lower BMI was linked to better asthma status and higher MVPA.
Conclusions:
- Suboptimal asthma status is linked to reduced physical activity in urban children.
- Weight status and cultural/contextual factors significantly influence this relationship.
- These factors represent important targets for future research and interventions to improve child health.

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.

Bronchodilators are critical in managing asthma, a chronic respiratory condition characterized by airway constriction due to inflammation and hyper-reactivity. Specifically, bronchodilators ease this constriction by relaxing the bronchial muscles, facilitating easier breathing.
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce...
