Numerator

Number of persons aged 18 years and over who are high risk for diabetes and who report trying to lose weight

Denominator

Number of persons aged 18 years and over without self reported diabetes who have a fasting glucose greater than or equal to 100 and less than 126mg/dl or an HbA1c value greater than or equal to 5.7%  and <6.5%.

Methodology

From the 2005-2008 National Health and Nutrition Examination Survey:

[NUMERATOR:]

To lower {your/his/her} risk for certain diseases, {are you/is s/he} now doing any of the following:

a. controlling {your/his/her} weight or losing weight?

  1. Yes
  2. No
  3. Refused
  4. Don't know
  5. Missing

[NUMERATOR and DENOMINATOR:]

{Other than during pregnancy, {have you/has SP}/{Have you/Has SP}} ever been told by a doctor or health professional that {you have/{he/she/SP} has} diabetes or sugar diabetes?

  1. Yes
  2. No
  3. Borderline
  4. Refused
  5. Don't know
  6. Missing

The population at high risk for developing diabetes is defined as persons who have pre-diabetes—this includes persons who have do not have doctor diagnosed diabetes (do not respond yes to ever being diagnosed with diabetes or sugar diabetes) and have either a fasting blood glucose level of greater than or equal to 100 or less than 126 mg/dl or have an A1c level of ≥5.7% to <6.5%.

Data for HbA1c are available for the whole sample, but data for fasting glucose are only measured for the morning examination session. For these analysis the cohort examined is restricted to persons in the AM exam session only.

Trend Issues

Hemoglobin A1c results for 2007-2008 (GHB_E) and 2009-2010 (GHB_F) were temporarily withdrawn in November 2011 to evaluate a shift to the right (increased values) in the distribution of Hemoglobin A1c in 2007-2010 compared to 1999-2006. After careful evaluation of participant data, laboratory quality control data and non-NHANES A1c studies, a cause for this shift in the distribution of Hemoglobin A1c could not be identified. Therefore, the Hemoglobin A1c data for 2007-2008 (GHB_E) and 2009-2010 (GHB_F) were re-released in March 2012 without changes to the data. The user will need to carefully consider the information presented in this analytic note when analyzing Hemoglobin A1c data from 1999-2010.

Interventions

Obesity Prevention and Control: Technology-Supported Multicomponent Coaching or Counseling Interventions to Reduce Weight and Maintain Weight Loss

Technology-supported multicomponent coaching or counseling interventions use technology to facilitate or mediate interactions between a coach or counselor and an individual or group, with a goal of influencing weight-related behaviors or weight-related outcomes.
