This is the third and final post in recognition of World Asthma Day, Tuesday May 2nd. This post looks at research from the University of Adelaide in South Australia. In particular, the researchers examined the relationship between soft drink consumption and asthma as well as chronic obstructive pulmonary disease (COPD) among a sample of adults in South Australia.

Using a random sample of South Australians phone interviews were conducted with adults ages 16 and older, with a mean of 47 years. In all, nearly 17,000 adults were interviewed.

Respondents were questioned regarding any diagnosis of asthma that was associated with symptoms over the past year, or use of typical asthma medications over the past year. Respondents were similarly queried regarding COPD diagnosis. Soft drink intake was associated by asking about the amount of soft drinks and sports drinks consumed in a typical day.

Results showed that higher levels of soft drink consumption were associated with a higher prevalence of asthma and COPD. Respondents who drank a half liter or more of soft drinks each day had a substantially higher prevalence of asthma (14.7%) compared to those who did not consume soft drinks (11.9%) A similar relationship was seen in COPD where those who drank a half liter or more of soft drinks each day had a prevalence of asthma of 6.0%, compared to only 4.2% in those who did not consume soft drinks.

In the U.S. the CDC estimates 1 in 12 adults has asthma. Women are more likely than men to have asthma. Given these statistics moderating our soft drink intake seems like a simple way to potentially limit one’s risk of asthma.
