Mothers' and fathers' cognitive and affective responses to epigenetics concepts.

Advances in our understanding of epigenetics present new opportunities to improve children's health through the counseling of parents about epigenetics concepts. However, it is important to first evaluate how parents respond to this type of information and determine the consequences of educating parents about epigenetics. We have taken an initial step toward this goal by assessing parental responses to an epigenetics learning module. Parents (n = 190, 126 mothers) responded to pre- and post-module survey questions. Prior to the module, parents reported that mothers' lifestyles prior to conception were more important for children's health than fathers' lifestyles prior to conception (t = 4.49, df = 316.5, P < 0.0001). However, after the module, there was no difference between ratings of the importance of mothers' and fathers' preconception lifestyles (t = 1.18, df = 319.8, P = NS). Furthermore, after viewing the module, parents increased their ratings of the importance of both mothers' (t = -5.65, df = 294.8, P < 0.0001) and father's (t = -9.01, df = 287.2, P < 0.0001) preconception lifestyles for child health. After viewing the module, most parents reported feelings of guilt and negativity regarding epigenetics (78 and 55%, respectively). When compared with lean parents, parents with overweight more often reported feelings of guilt (χ ² =10.27, P = 0.001). This work represents an important first step in evaluating parental responses to epigenetics concepts.
