Primary care referral to Weight Watchers is associated with weight loss, HbA1c reduction
TUESDAY, Oct. 17, 2017 (HealthDay News) -- Primary care referral along with a commercial weight management provider can deliver an effective diabetes prevention program (DPP), according to a study published online Oct. 16 in BMJ Open Diabetes Research & Care.
Carolyn Piper, from the Department of Public Health in London, and colleagues evaluated whether a DPP delivered by a commercial weight management company using a primary care referral pathway could reduce progression to type 2 diabetes. A total of 166 patients with non-diabetic hyperglycemia were referred by 14 primary care practices. The intervention included an initial 90-minute session followed by 48 weekly Weight Watchers group meetings.
Of the referred patients, 149 were eligible to participate; 79 percent of them attended an activation session, and 77 percent started the weekly sessions (75 percent female, 90 percent white). The researchers found that DPP resulted in a mean reduction in HbA1c of 2.84 mmol/mol at 12 months. More than one-third of patients (38 percent) returned to normoglycemia, while 3 percent developed type 2 diabetes at 12 months. Over the 12-month period there was a mean weight reduction in BMI of 3.2 kg/m2.
"The lifestyle changes and weight loss achieved in the intervention translated into considerable reductions in diabetes risk, with an immediate and significant public health impact," conclude the authors.
