The Analysis of BMI, Asthma Prevalence, and Lung Functions of Schoolchildren in Southern Taiwan
An observational study of Asthma and Obesity, run by Kaohsiung Medical University Chung-Ho Memorial Hospital.
Trial summary
The prevalence of obesity and asthma has increased in recent decades. We investigated the relationship between body mass index (BMI) and lung function, and also tried to determine if asthma prevalence differs between obese and non-obese children. Read more about this study

About this study
The prevalence of obesity and asthma has increased in recent decades. We investigated the relationship between body mass index (BMI) and lung function, and also tried to determine if asthma prevalence differs between obese and non-obese children. We propose this cross-sectional, retrospective analysis to figure out whether the BMI is associated with elevated prevalence of asthma, and how their lung function changes in different BMI groups.
