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 ) .
The Live Well, Be Well study: a community-based, translational lifestyle program to lower diabetes risk factors in ethnic minority and lower-socioeconomic status adults.
OBJECTIVES We evaluated a community-based , translational lifestyle program to reduce diabetes risk in lower-socioeconomic status ( SES ) and ethnic minority adults . METHODS Through an academic-public health department partnership , community-dwelling adults at risk for diabetes were r and omly assigned to individualized lifestyle counseling delivered primarily via telephone by health department counselors or a wait-list control group . Primary outcomes ( 6 and 12 months ) were fasting glucose level , triglycerides , high- and low-density lipoprotein cholesterol , weight , waist circumference , and systolic blood pressure . Secondary outcomes included diet , physical activity , and health-related quality of life . RESULTS Of the 230 participants , study retention was 92 % . The 6-month group differences for weight and triglycerides were significant . The intervention group lost 2 pounds more than did the control group ( P=.03 ) and had decreased triglyceride levels ( difference in change , 23 mg/dL ; P=.02 ) . At 6 months , the intervention group consumed 7.7 fewer grams per day of fat ( P=.05 ) and more fruits and vegetables ( P=.02 ) than did control participants . CONCLUSIONS Despite challenges design ing effective translational interventions for lower-SES and minority communities , this program modestly improved some diabetes risk factors . Thus , individualized , telephone-based models may be a promising alternative to group-based interventions
