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 InnvaDiab-DE-PLAN study: a randomised controlled trial with a culturally adapted education programme improved the risk profile for type 2 diabetes in Pakistani immigrant women.
The objective of the present study was to explore whether a culturally adapted lifestyle education programme would improve the risk factor profile for type 2 diabetes ( T2D ) and the metabolic syndrome ( MetS ) among Pakistani immigrant women in Oslo , Norway . The r and omised controlled trial ( the InnvaDiab study ) , lasting 7 ± 1 months , comprised six educational sessions about blood glucose , physical activity and diet .  Participants ( age 25 - 62 years ) were r and omised into either a  control ( n 97 ) or an  intervention ( n 101 ) group . Primary outcome variables were fasting and 2 h blood glucose , and secondary outcome variables were fasting levels of insulin , C-peptide , lipids , glycated Hb , BMI , waist circumference and blood pressure , measured 1 - 3 weeks before and after the intervention . During the intervention period , the mean fasting blood glucose decreased by 0·16 ( 95 % CI -0·27 , -0·05 ) mmol/l in the intervention group , and remained unchanged in the control group ( difference between the groups , P=0·022 ) . Glucose concentration 2 h after the oral glucose tolerance test decreased by 0·53 ( 95 % CI -0·84 , -0·21 ) mmol/l in the intervention group , but not significantly more than in the control group . A larger reduction in fasting insulin was observed in the intervention group than in the control group ( between-group difference , P= 0·036 ) . Among the individuals who attended four or more of the educational sessions ( n 59 ) , we found a more pronounced decrease in serum TAG ( -0·1 ( 95 % CI -0·24 , 0·07 ) mmol/l ) and BMI ( -0·48 ( 95 % CI -0·78 , -0·18 ) kg/m² ) compared with the control group . During the intervention period , there was a significant increase in participants having the MetS in the control group ( from 41 to 57 % ) , which was not seen in the intervention group ( from 44 to 42 % ) . Participation in a culturally adapted education programme may improve risk factors for T2D and prevent the development of the MetS in Pakistani immigrant women
