Bodyodor has been a subject of interest since olden times. The attention body odorstill gets is fascinating especially when an intriguing study titledThe Smell of Age: Perception and Discrimination of Body Odors of Different Ages by Dr. Johan Lundstrmand colleagues, Monell University, Philadelphia,shows that the smell of older people isless intense and less unpleasant thanbody odors originating from Young and Middle-age donors.Dr. Lundstrm shares more details of his study with Medindia.
Q. In the study conducted, did the weight of the person have any impact on body odor?
A. No, subject groups were matched for general health, which included the BMI. It was not clear in the paper since it fell within the general screening category. However, it is something we routinely do.
A. Yes, the more you sweat the more body odor you tend to emit. Also, if a person is obese and has skin flaps, body odor accumulates under the flaps and becomes a breeding ground for bacteria.
Q. What were the selection criteria for participants of the study who were asked to evaluate the odors?
Q. During the study, what kind of diet was prescribed? Did you experiment with the diet to see how that might affect body odor?
A. Volunteers were asked to refrain from eating spicy food and foods that we know would affect a persons body odor such as garlic, asparagus, certain spices and of course food additives.
Q. On an average day, people use perfumes, talc, deodorants, how do you think that would alter the results of your current study on body odor?
Q. Why were sexual preferences a factor?
Q. Three age groups were selected, all of them were adults, if the comparison should be between body odor of old people to that of infants (most of them have lactic smell) how would the results fare?
A. I believe that the discrimination performance would be even greater since infants tend to have a very characteristic odor.
