Which state reported the lowest percentage of asthma in the Comparative Health Index?

Iowa is the correct choice for the state with the lowest percentage of asthma in the Comparative Health Index. This designation typically reflects the results of public health studies and surveys that measure respiratory conditions across various states. Factors contributing to Iowa's lower asthma rates may include its geographical characteristics, lower levels of urban pollution compared to larger states, and possibly healthier lifestyles that can mitigate asthma triggers.

Aspects such as air quality, availability of healthcare resources, and community health initiatives also play a critical role in managing asthma rates. States with significant urban centers, like California and New York, often have higher asthma rates attributed to pollution and environmental factors. Meanwhile, Florida, with its unique climate and demographic factors, can also experience elevated asthma levels.
