Introduction
Studies have demonstrated the benefit of weight loss and physical activity for diabetes
prevention among those with prediabetes. Despite this evidence, only about half of
people with prediabetes report engaging in these behaviors. One presumed barrier is
low patient awareness of prediabetes. The purpose of this study is to examine the
impact of prediabetes awareness on the odds of engagement in diabetes risk–reduction
behaviors.
Methods
A pooled cross-sectional analysis of adults from two cycles (2007–2008, 2009–2010)
of the National Health and Nutrition Examination Survey was conducted. Those with
prediabetes were identified by excluding people with self-reported diabetes and then
screening for hemoglobin A1c values between 5.7% and 6.4%. This group was then divided
based on self-reported prediabetes. Multivariate logistic regression was used to estimate
the effect of prediabetes awareness on the odds of engagement in physical activity,
weight management, and the combination of physical activity and weight management.
Results
Of those meeting the defined criteria for prediabetes (n=2,694), only 11.8% (n=288) were aware of their status. Prediabetes-aware individuals had higher odds of
engagement in the combination of moderate physical activity plus BMI-appropriate weight
management (AOR=1.5, 95% CI=1.1, 2.0), and the combination of at least 150 minutes/week
of moderate activity and 7% weight loss in the past year (AOR=2.4, 95% CI=1.1, 5.6).
Conclusions
Prediabetes-aware adults have increased odds of engagement in physical activity and
weight management. Increasing patients’ awareness of prediabetes could result in increased
performance of exercise and weight management behaviors and, most importantly, decreased
risk of future diabetes.
