Study summary

This study will examine the impact diabetes genetic counseling on patient motivation and disease prevention behaviors among subjects with pre-diabetes. Intervention subjects will be provided with their individual diabetes genotype risk score derived from aggregating the combined results of 37 diabetes risk-associated genetic loci. Controls will not be tested. All subjects will be enrolled in a 12-week diabetes prevention program.

Read the detailed description

This study will examine the impact diabetes genetic counseling on patient motivation and disease prevention behaviors among subjects with pre-diabetes. We will randomize subjects with pre-diabetes to genetic testing vs. no genetic testing in order to obtain an unconfounded test of the hypothesis that genetic testing will change patient behavior. Intervention subjects will be provided with their individual diabetes genotype risk score derived from aggregating the combined results of 37 diabetes risk-associated genetic loci. Because patients can receive either "Higher risk" or "Lower risk" genetic test results, we will separately examine the impact of "Higher risk" and "Lower risk" test results compared to untested controls. All subjects will be enrolled in a 12-week diabetes prevention program.

Study arms

  • Experimental
    Diabetes Genetic Counseling

    Subjects will have been genotyped and will received genetic counseling based on their results

    Behavioral: Diabetes Genetic Counseling

  • Placebo comparator
    No Genotyping or Counseling

    Patients will not be genotyped and will therefore not receive genetic counseling

    Behavioral: No genetic counseling

Interventions

  • BehavioralDiabetes Genetic Counseling

    Subjects will be genotyped based on a 37-allele aggregate score and counseled regarding the implications of the results prior to enrollment in a 12-week diabetes prevention program

  • BehavioralNo genetic counseling

    These subjects will not be genotyped or counseled prior to enrollment in a 12-week diabetes prevention program
