60% Lower Risk of Type 2 DiabetesJoin D*action

GrassrootsHealth Analysis

GrassrootsHealth did an analysis of type 2 diabetes, comparing GrassrootsHealth D*action participants with the National Health and Nutrition Examination Survey cohort (NHANES).

  • diabetes-chartGrassrootsHealth participants ≥ 20 years of age (N=4933) had a median serum level of 41 ng/ml and a type 2 diabetes incidence rate of 3.7 per 1000 population.
  • In contrast, the NHANES cohort from 2005-6 (N=4078) had a median serum level of 22 ng/ml and a type 2 diabetes incidence rate of 9.3 per 1000 population.
  • Participants in the GrassrootsHealth cohort had a 60% lower risk of type 2 diabetes compared to participants in the NHANES cohort after adjusting for age, gender, race, BMI and smoking status.

  • 12,055 women were enrolled and 10,366 children were included in the analysis.
  • Data was taken during the infants’ first year of life about frequency of vitamin D supplementation and whether it was at, above or below the recommended dose of 2000 IU/day.
  • Children with regular supplementation, regardless of dose, had a lower rate of type 1 diabetes than those who did not.
  • Among those who received regular vitamin D supplementation, those receiving at least 2000 IU/day had an 80% reduced risk of type 1 diabetes compared to those who received smaller doses.
