This study from the Journal of Asthma focuses on developing a better understanding of the relationship among asthma, obesity, and health behaviors in African American youth.  

The study participants included 195 African Americans aged 11 to 18. Cross-sectional relationships were assessed among asthma, body mass index (BMI) percentile, caloric intake, dietary inflammatory index, moderate-vigorous physical activity, and sedentary time. Asthma status was self-reported via questionnaire, and weight status was assessed using BMI percentile. Caloric intake and dietary inflammatory index were evaluated by questionnaire. Moderate-vigorous physical activity and sedentary time were measured using accelerometry. 

The researchers found that adolescents with asthma were significantly more overweight or obese and consumed a higher inflammatory diet than their peers without asthma. This finding held after adjusting for all covariates. 

Overall, the researchers concluded that the data presented do not conclusively indicate that asthma results in obesity due to behavioral factors. However, a causal pathway may exist and deserves further research. A call to action is made advocating for longitudinal studies to gather more accurate data that can be used to formulate clinical and public health solutions for the prevention and treatment of asthma and obesity in Black youth [1].
