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 ) .

Some slight departures from the protocol of individual r and omization affecting only a small subset of participants in the Prevencion con Dieta Mediterranea ( PREDIMED ) trial ( at most 14 % ) occurred and prompted a thorough re analysis of data and republication of the main PREDIMED paper ( see Estruch et al. , Primary prevention of cardiovascular disease with a  Mediterranean diet supplemented with extra-virgin olive oil or nuts . N Engl J Med 2018;378:e34 ) . The authors report the
