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 ) .
Piloting a behavioral intervention delivered through interactive voice response telephone messages to promote weight loss in a pre-diabetic population.
OBJECTIVE To pilot test the feasibility and effectiveness of interactive voice response ( IVR ) calls targeting physical activity and healthful eating as strategies for weight loss for patients with pre-diabetes . METHODS Participants ( N=77 ) who engaged in a 90-min diabetes prevention class were r and omly assigned to receive IVR support targeting physical activity and nutrition weight loss strategies or to a no-contact control .  Physical activity , dietary intake , and body weight were assessed prior to and following the 3-month intervention . RESULTS Eighty-five percent of the intervention participants completed at least half of the intervention . Participants assigned to receive the intervention lost an average of 2.6 % of body weight during the 3 months while control participants lost an average of 1.6 % . To determine the effect of the calls when used we found that those who used the system lost approximately 3 % of body weight which approached significance when compared to controls ( p<.06 ) . CONCLUSION IVR holds promise for follow-up encounters with patients with pre-diabetes . PRACTICE IMPLICATION S IVR can be used to provide physical activity and nutrition counseling that can enhance the potential reach and effectiveness of health professionals working with patients who have diabetes while placing a minimal burden on financial re sources and staff time
