Table 5 Impact of genetic test scores and risk perception on changes in diet and exercise

From: Diet and exercise changes following direct-to-consumer personal genomic testing

Variable β (95% CI), p-value R2
Cardiometabolic genetic test score  
 Fruit Servings per Day β = -0.04 (-0.14, 0.06), p = 0.42 0.18
 Vegetable Servings per Day β = -0.02 (-0.11, 0.08), p = 0.73 0.14

  1. Adjusted for: baseline behavior, company, season change, age, gender, education, income, race, ethnicity, baseline BMI, baseline self-reported health
  2. β estimates are raw coefficients
  3. aAlso adjusted for baseline perceived riskNote: The presented model R2 values (with genetic risk score/risk perception) are all equivalent to the covariate-only R2 values for each fitted model
