A 12-week diabetes prevention programme can reduce body mass index in pre-diabetes patients in primary care.
The US trial data found that patients randomised to a coach-led intervention programme experienced significantly greater reductions in mean BMI at 15 months, compared with those on a self-directed version of the intervention and usual care – with decreases of 2.2, 1.6 and 0.9 respectively.
Weight loss was also significantly greater in the coach-led intervention group than those in the self-directed group or those receiving usual care, with reductions of 6.3kg, 4.5kg and 2.4kg respectively.
Self-directed participants showed significantly greater reductions in weight and BMI than those getting usual care.
The trial involved 241 patients, with the prevention programme consisting of 12 face-to-face classes for the coach-led group and a home-based DVD for the self-directed patients.
The US researchers concluded: ‘Successful adaptation of proven lifestyle interventions such as the diabetes prevention programme for multiple channels of delivery, all populations at risk and primary care settings will be critical to stem the tide of obesity and lessen its disease burden.’
