This review found no clear or consistent evidence that genetic risk communication alone either raises motivation or translates into actual change in dietary intake or physical activity to reduce the risk of cardiometabolic disorders in adults .
Genetic risk prediction of chronic conditions including obesity , diabetes and CVD currently has limited predictive power but its potential to engage healthy behaviour change has been of immense research interest .
We aim ed to underst and whether the latter is indeed true by conducting a systematic review and meta- analysis investigating whether genetic risk communication affects motivation and actual behaviour change towards preventative lifestyle modification .
Impact of Delivery Models on Understanding Genomic Risk for Type 2 Diabetes
Background : Genetic information , typically communicated in-person by genetic counselors , can be challenging to comprehend ; delivery of this information online - as is becoming more common - has the potential of increasing these challenges . Methods : To address the impact of the mode of delivery of genomic risk information , 300 individuals were recruited from the general public and r and omized to receive genomic risk information for type 2 diabetes mellitus in-person from a board-certified genetic counselor or online through the testing company 's website . Results : Participants were asked to indicate their genomic risk and overall lifetime risk as reported on their test report as well as to interpret their genomic risk ( increased , decreased , or same as population ) . For each question , 59 % of participants correctly indicated their risk . Participants who received their results in-person were more likely than those who review ed their results on-line to correctly interpret their genomic risk ( 72 vs. 47 % , p = 0.0002 ) and report their actual genomic risk ( 69 vs. 49 % , p = 0.002 ) . Conclusions : The delivery of personal genomic risk through a trained health professional result ed in significantly higher comprehension . Therefore , if the online delivery of genomic test results is to become more widespread , further evaluation of this method of communication may be needed to ensure the effective presentation of results to promote comprehension
