Olfaction

The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
The olfactory receptors are embedded in the cilia of the...

Area of Science:

  • Pediatric Olfaction
  • Sensory Science
  • Cross-cultural Psychology

Background:

  • Limited research exists on odor recognition in children from Poland and Eastern Europe.
  • Olfactory screening tests are valuable diagnostic tools for children's health.

Purpose of the Study:

  • To determine odors recognizable by Polish children for a potential screening olfactory test.
  • To establish normative data for olfactory recognition in Eastern European children.

Main Methods:

  • A 21-odor olfactory test was administered to 91 children (aged 2.9-10 years) in Warsaw.
  • Children were grouped by age, and 85 completed the full test.
  • Statistical analysis identified significant factors influencing odor recognition.

Main Results:

  • Age significantly impacts the number of odors children can identify (p=0.0001; r=0.676).
  • Six odors (bubble gum, lemon, cola, mint, toffee, fish) were identified for the screening test.
  • 96.5% of children correctly identified at least 4 of the 6 odors, establishing a norm.

Conclusions:

  • Olfactory evaluation is feasible in children from age 3.
  • Odor recognition is influenced by age, geographic location, and eating habits.
  • The 6-odor test is valid, reliable, fast, easy, and inexpensive for olfactory screening in Eastern European children.
