Abstract

Objective: To compare the nutritional status, chronotype and eating behavior of a subject who simultaneously has the rs3749474T and rs4864548A polymorphisms to groups of subjects who have only one of these polymorphisms. Methods: The presence of the polymorphisms was established by PCR. BMI, cardiovascular risk, and fat percentage were determined as described by Durnin and Womersley and the Siri equation. The TFEQ-P19 questionnaire (adapted to the Chilean population) and the Hor-ne-Ostberg questionnaire were applied. Results: The subject with both polymorphisms presented obesity, cardiovascular risk, and late-night chronotype. Its scores on the dimensions of uncontrolled feeding and emotional feeding were low, and its score for cognitive restriction was the highest. Conclusions: The presence of the TA haplotype (rs3749474; rs4864548A) would increase the possibility of having a late-night type chronotype, risk of obesity, and cardiovascular risk associated with waist centimeters.
