Olfactory Function in Greenhouse Workers With Allergic Rhinitis Assessed by Sniffin' Sticks Testing

Area of Science:

• Occupational Health
• Otorhinolaryngology
• Environmental Health

Background:

• Allergic rhinitis (AR) is a common condition affecting many individuals.
• Greenhouse workers are potentially exposed to various environmental factors.
• Olfactory dysfunction can significantly impact quality of life.

Purpose of the Study:

• To assess olfactory perceptual ability in greenhouse workers diagnosed with allergic rhinitis.
• To compare olfactory function between greenhouse workers with AR and healthy controls.
• To explore potential factors influencing olfactory ability in this population.

Main Methods:

• The study involved 51 greenhouse workers with AR (study group) and 49 healthy volunteers (control group).
• Olfactory perception was evaluated using the Sniffin' Sticks test battery.
• Statistical analyses were performed to compare scores between groups and identify influencing factors.

Main Results:

• Greenhouse workers with AR demonstrated significantly lower overall olfactory scores compared to controls.
• Specific odorants (pen 6 and pen 12) were more difficult for the AR group to identify.
• A higher prevalence of anosmia and hyposmia was observed in the AR group.

Conclusions:

• Greenhouse workers with allergic rhinitis exhibit decreased olfactory perceptual ability.
• Occupational exposures (gases, pesticides) and smoking may contribute to olfactory decline.
• The use of protective equipment like masks and clothing could be beneficial in preventing olfactory impairment.
