This observation, which is consistent with the lack of interaction between fitness and fatness (38), supports the concept that fitness ameliorates the unfavorable CVD risk factor profile driven by increased adiposity through mechanisms independent, at least partly, of weight loss.
Further exploration of the interaction between fitness and ethnicity and the obesity paradox is warranted.
We found no statistically significant interaction between fitness and PA in any of the above models.
Further studies are needed for the interaction of fitness costs of antibiotic resistance with other factors.
Hatchery males left fewer offspring than wild males only when mating with hatchery females, suggesting a possible negative interaction for fitness, but the result was not statistically significant.
When environmental conditions vary across sites, a genotype × environment interaction for fitness may permit natural selection for LA at individual sites (Kawecki and Ebert 2004), resulting in a LIB pattern.
We did not observe any differences between boys and girls when considering SBacc in these associations, nor did we observe a statistically significant interaction between fitness and PA in any of these analyses.
Antagonistic interactions induce fitness costs on both species: successful interactions come at a cost for species X while unsuccessful interactions come at a cost for species Y.
Thus, Ford invokes genotype-by-environment interactions for fitness as well as gene-gene interactions for fitness in his cases of rapid evolution.
There were no significant interactions between fitness and each obesity measure with IFG and type 2 diabetes risks, using interaction terms in the Cox regression models and comparing stratum-specific risk estimates in the stratified analyses.
