PPARa L162A, PPARg 12A, PPARβ/d rs226766 , and PGC-1a G482S genotype distributions were compared with TFEQ-R18 and ecSI scores; responses were gender-specific and paralleled published values. Results confirmed less emotional eating (EE) (P<.001), cognitive restraint (CR) (P<.001) and uncontrolled eating (UE) (P=.1) with EC (ecSI score >= 32). Subjects in the lowest ecSI tertile had significantly more CR (P<.001), EE (P<.001), and UE (P=.007).
The homozygous G/G PPARβ/d genotype tended (P=.06) toward less UE; females with the homozygous G/G PPARβ/ genotype tended (P=.1) toward less CR than males. Homozygous A/A PPARg genotype tended (P=.08) toward less CR and significantly more UE (P=.04). Students of homozygous S/S PGC-1 genotype (n=35) tended not to be eating competent (P=.05) and to be in the lowest ecSI tertile (P=.14). The PPARβ/d genotype and gender interaction was significant (P=.04) with higher ecSI scores for males (35.3 ± 5.8 vs. 30.8± 4.9) who were homozygous G/G. These data support the hypothesis of a link between EC and PPARβ/d and PGC-1a genotypes.
