Body mass index and serum periostin
In according with the previous adulthood studies (21, 22), we found a
negative correlation between serum periostin levels and body mass index
in children with asthma along with healthy controls. In our previous
studies, we have demonstrated associations between anthropometric
measures and asthma severity along with pulmonary functions (23-25). In
the current study, our results did not reveal an independent association
between body mass index and asthma severity. The different study design
and the lack of controls group with obese children is the most plausible
explanation. Addition of serum periostin measurement into the studies
can help us to better understand the interaction between obesity and
asthma in the future.
