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 ) .
A Randomized-Controlled, Pilot Intervention on Diabetes Prevention and Healthy Lifestyles in the New York City Korean Community
Asian Americans experience diabetes at a higher rate than non-Hispanic whites . Diabetes prevention programs using lifestyle interventions have been shown to produce beneficial results , yet there have been no culturally-tailored programs for diabetes prevention in the Korean community . We explore the impact and feasibility of a pilot Community Health Worker ( CHW ) intervention to improve health behaviors and promote diabetes prevention  among Korean Americans using a r and omized controlled trial . Between 2011 and 2012 , a total of 48 Korean Americans at risk for diabetes living in New York City ( NYC ) participated in the intervention . Participants were allocated to treatment or control groups . A community-based participatory research approach guided development of the intervention , which consisted of 6 workshops held by CHWs on diabetes prevention , nutrition , physical activity , diabetes complications , stress and family support , and access to health care . Changes over 6 months were examined for clinical measurements ( weight , BMI , waist circumference , blood pressure , glucose , and cholesterol ) ; health behaviors ( physical activity , nutrition , food behaviors , diabetes knowledge , self-efficacy , and mental health ) ; and health access ( insurance and self-reported health ) . In this small pilot study , changes were seen in weight , waist circumference , diastolic blood pressure , physical activity nutrition , diabetes knowledge , and mental health . Qualitative findings provide additional context ual information that inform ways in which CHWs may influence health outcomes . These findings demonstrate that a diabetes prevention program can be successful among a Korean American population in NYC , and important insight is provided for ways that programs can be tailored to meet the needs of vulnerable population
