Implication

Comparative cohort study finds lower respiratory disease rates but higher symptom prevalence in farmers, suggesting early microbial protection alongside occupational airway irritation.

Key Points

To evaluate the prevalence of respiratory diseases and symptoms among farmers and their spouses compared with the general United States population.
Compared self-reported respiratory outcomes in 43,548 participants from the Agricultural Health Study (AHS) in Iowa and North Carolina with adult data from NHANES (2005–2010).
Controlled statistical models for smoking, body mass index, and demographic population characteristics.
Overall asthma prevalence in the AHS cohort was 7.2% (95% CI 6.9 to 7.4), which was 52% of the prevalence observed in NHANES (13.8%, 95% CI 13.3 to 14.3).
Adult-onset asthma prevalence among men was 3.6% in AHS versus 3.7% in NHANES.
AHS participants had lower prevalences of chronic bronchitis and emphysema, but experienced higher prevalences of current symptoms including cough, wheeze, and phlegm, especially among men.
