Background: Currently, there is a growing concern about the disease burden of child asthma particularly due to high body mass index (BMI). The prevalence and disease burden of asthma differ between developing and developed countries, with implications on disease intervention. Therefore, we provide a comparative analysis of childhood asthma between China and the United States of America (USA).
Methods: Using the Global Burden of Disease (GBD) 2019 data, we estimated and compared the age-standardized prevalence, disability-adjusted life years (DALYs), years of life lost (YLLs), years of lost due to disability (YLDs), DALYs due to high BMI of asthma in children aged 1-14 years in China and the USA. Joinpoint regression analysis was applied to assess changes in temporal trends.
Results: DALYs due to high BMI and the ratio of DALYs to DALYs due to high BMI in children with asthma showed a significant upward trend in both countries and were higher in males than in females. Almost all epidemiological indicators of asthma showed a hump of curve from 2014 to 2019, and peaked in 2017. There was a decreasing trend of YLLs for asthma in children both countries, while China has a saliently greater decreasing trend.
Conclusion: The disease burden caused by high BMI of childhood asthma was on the rise in children with asthma in both China and the USA. High BMI needs to be taken more into account in the development of future policies for the prevention, control, and treatment of childhood asthma. However, the increasing trend of this disease burden in American children was significantly lower than that in Chinese children. We recommend learning from the American government to impose a high-calorie tax, increase physical exercise facilities, and provide better health care policies.
