Asthma-related lung function and physical activity patterns among children living in urban neighborhoods

Abstract

Objective

Black and Latino American children residing in urban environments are at increased risk for comorbid asthma and obesity. Physical activity (PA) is a modifiable behavior known to contribute to the asthma-obesity phenotype. While research has indicated links between optimal asthma status and high PA among children, little is documented about whether this group may display other asthma and PA patterns that warrant clinical attention and tailored interventions.

Methods

Children with persistent asthma (N = 97) ages 7–9 and their caregivers from urban neighborhoods completed daily measures of asthma status and moderate-to-vigorous physical activity (MVPA) and questionnaires about health and sociodemographic characteristics. Clinical asthma guidelines (e.g. FEV1 ≥ 80%) and sample means were used to categorize children into high or low lung function and MVPA patterns. Individual, family, and contextual differences across lung function and MVPA patterns were investigated.

Results

Twenty-nine percent of participants displayed optimal lung function and high MVPA. The remainder of the sample exhibited various less optimal patterns (e.g. poorer lung function and high MVPA). Caregivers of children displaying poorer lung function and high MVPA levels were more likely to report asthma related fears than caregivers of children with low MVPA levels regardless of lung function status.

Conclusions

Asthma and PA interventions can be tailored to better address each child’s unique clinical and behavioral patterns. An enhanced understanding of risk factors for suboptimal patterns of asthma status and PA may aid in multicomponent intervention efforts.
