To establish a relation between the body fat percentage (BF %) and Pupil cycle time (PCT) in healthy adult male.
The Pupil Cycle time (PCT) is the parasympathetic response in the eye. This is a sensitive and specific test to determine the ophthalmological parasympathetic response. Cardiac parasympathetic tone is comparable with the ophthalmological parasympathetic tone.
The PCT is calculated by throwing a beam of light on the edge of the pupil and measuring the time of a single constriction and dilatation of the pupil. Body fat percentage was calculated from the body weight and body density. Body density is calculated from log of 4-skinfold thicknesses in different parts of the body.
We obtained that the mean of fat percent in three groups was 14.2±4.47% in the undernourished, 19.49±5.61% in well-nourished and 29.3±2.13 in overweight/obese. In the present study, we established the fact that the PCT is altered according to the body fat percentage irrespective to their BMI.
It is established that there is a decrease in parasympathetic activity when there is more percentage of fat in body irrespective of their BMI and vice versa.
