Title: Diabetes Quantified self-tracking Study

 

Summary: Quantified self tracking devices and smartphone health applications have been proliferating in the consumer sector for the measurement of a wide variety of health conditions. This study seeks to investigate the use of quantified self tracking devices in the health context and linkage between self tracking data and genomic profiles, physical biomarkers, behavioral change, and personalized intervention.

 

Hypothesis: Quantified self tracking devices may be leading to interesting new methods of discovery, empowerment, and health self-management amongst individuals. Specifically, quantified self tracking device data generates a large volume of attribute-rich data that could have novel correlations with both traditional and health 2.0 data streams such as genomic data, blood test data, online phenotypic surveys, and self-experimentation data. Baseline hemoglobin measures may already predict diabetes in high-risk individuals (Heianza 2012).

 

Genotype data: 

  • SNPs associated with resting heart rate: COMT Val158Met rs4680,[i] and GJA1 (rs9398652, rs11154022), MYH6 (rs452036, rs365990), MYH7 (rs223116), Intergenic (rs17287293), SLC35F1 (rs281868), SLC12A9 (rs314370), UfSp1 (rs12666989), FADS1 (rs174547), and CD34 (rs2745967).[ii]
  • SNPs associated with insulin resistance: TCF7L2 (rs7903146), PPARG (rs1801282, rs6802898, rs2197423 ), KCNJ11 (rs5219), IGF2BP2 (rs4402960), HHEX (rs1111875), CDKAL1 (rs4712523), SLC30A8 (rs13266634), WFS1 (rs10012946), CDKN2A/B (rs2383208), KCNQ1 (rs2237892), and MTNR1B (rs1387153).[iii]

 

Phenotype data:

Quantitative data: Hemoglobin & cholesterol profiles at baseline & after three months (HgbA1c + Chem 12 Panel + Lipid Profile - $69), and for intervention group B, quantitative data output from glucometer tracking devices. Ideally, an LDL particle size and an HS-CRP test (both must be doctor-ordered) would also be included to indicate diabetes risk and measure of overall current inflammation in the body

Qualitative data: standardized user survey instruments

 

Study protocol: Minimum n=100, goal n=300. Ongoing open enrollment in a study with one month duration. Participants randomized into three groups: 

A: Control group: No intervention

B: Experimental group 1: maintain a daily food consumption and exercise diary and conduct daily glucometer measurements (2x daily, fasting and postprandial (1-2 hrs after a meal)

C: Experimental group 2: maintain a daily food consumption and exercise diary

 

Study conduct: The study will be conducted in a healthy crowdsourced cohort. Enrollment will be open and ongoing, with at minimum 100 participants sought for the first phase of data analysis. Study recruitment and operation will be via the internet-based health collaboration community Genomera.com. The process is that participants will join the study, complete an informed consent process, agree to share personal genotyping data for the required variants, and complete the online survey instruments and other requirements. Personalized feedback will be provided to participants.
