The cost of intervention per participant delivered by dietitians was lower than interventions delivered by non-dietitians , although few studies reported costs .
Lifestyle interventions are effective in reducing body weight and glucose-related outcomes .
Dietitian-delivered interventions , compared with those delivered by other personnel , achieved greater weight reduction .
No consistent trend was identified across different delivery channels
BACKGROUND Type 2 diabetes is a significant public health concern .
With the completion of the Diabetes Prevention Program , there has been a proliferation of studies attempting to translate this evidence base into practice .
However , the cost , effectiveness , and cost-effectiveness of these adapted interventions is unknown .
OBJECTIVE The purpose of this systematic review was to conduct a comprehensive meta- analysis to synthesize the effectiveness , cost , and cost-effectiveness of lifestyle diabetes prevention interventions and compare effects by intervention delivery agent ( dietitian vs non-dietitian ) and channel ( in-person vs technology-delivered ) .
Translating the Diabetes Prevention Program into an Online Social Network
Purpose The purpose of this study was to evaluate the efficacy of Prevent , an online social network-based translation of the Diabetes Prevention Program ( DPP ) lifestyle intervention , against the Centers for Disease Control and Prevention ( CDC ) Diabetes Prevention and Recognition Program ( DPRP ) outcome st and ards and weight loss outcomes of other DPP translations . Methods Two hundred twenty participants previously diagnosed with prediabetes were recruited online and enrolled in Prevent , a DPP-based group lifestyle intervention that integrates a private online social network , weekly lessons , health coaching , and a wireless scale and pedometer . Participants underwent a core 16-week intensive lifestyle change intervention and were then offered to continue with a post-core lifestyle change maintenance intervention , with the entire intervention ( core plus post-core ) totaling 12 months . Results One hundred eighty-seven participants met inclusion criteria for the core program and achieved an average of 5.0 % and 4.8 % weight loss at 16 weeks and 12 months , respectively . They also had a 0.37 % reduction in their A1C level at final measurement . One hundred forty-four of these same participants also met inclusion criteria for the post-core program and achieved an average of 5.4 % and 5.2 % weight loss at 16 weeks and 12 months , respectively , and a 0.40 % reduction in A1C at final measurement . Conclusion Results indicate that Prevent meets CDC DPRP outcome st and ards for diabetes prevention programs and performs favorably to other DPP translations . Considering national initiatives to address the obesity and diabetes epidemics , online delivery platforms like Prevent offer an effective and scalable solution
