The Pre-diabetes Risk Education and Physical Activity Recommendation and Encouragement (PREPARE) programme study: are improvements in glucose regulation sustained at 2 years?

Abstract

To determine whether improvements in glucose regulation following the PREPARE structured education programme were sustained at 24 months. Ninety-eight overweight or obese individuals with impaired glucose tolerance were randomized to receive: (1) advice leaflet, (2) 3-h structured education programme aimed at promoting physical activity, (iii) 3-h structured education with personalized pedometer use. The primary outcome was change in 2-h post-challenge plasma glucose. Seventy-three (74%) individuals were included for analysis at 24 months; age 65 ± 8 years, BMI 29.3 ± 4.8 kg/m(2), South Asian ethnicity 21%. A statistically significant reduction in 2-h glucose of -1.6 mmol/l (-0.4 to -2.7) was seen in the education-with-pedometer group compared with the control group. There is no significant difference in the education-only group. Improvements in glucose regulation following a pragmatic group-based structured education with pedometer use were sustained at 24 months.
