Prevention of Type 2 Diabetes by lifestyle intervention in an Australian primary health care setting: Greater Green Triangle (GGT) Diabetes Prevention Project
Background R and omised controlled trials demonstrate a 60 % reduction in  type 2 diabetes incidence through lifestyle modification programmes . The aim of this study is to determine whether such programmes are feasible in primary health care . Methods An intervention study including 237 individuals 40–75 years of age with moderate or high risk of developing type 2 diabetes . A structured group programme with six 90 minute sessions delivered during an eight month period by trained nurses in Australian primary health care in 2004–2006 . Main outcome measures taken at baseline , three , and 12 months included weight , height , waist circumference , fasting plasma glucose and lipids , plasma glucose two hours after oral glucose challenge , blood pressure , measures of psychological distress and general health outcomes . To test differences between baseline and follow-up , paired t-tests and Wilcoxon rank sum tests were performed . Results At twelve months participants ' mean weight reduced by 2.52 kg ( 95 % confidence interval 1.85 to 3.19 ) and waist circumference by 4.17 cm ( 3.48 to 4.87 ) . Mean fasting glucose reduced by 0.14 mmol/l ( 0.07 to 0.20 ) , plasma glucose two hours after oral glucose challenge by 0.58 mmol/l ( 0.36 to 0.79 ) , total cholesterol by 0.29 mmol/l ( 0.18 to 0.40 ) , low density lipoprotein cholesterol by 0.25 mmol/l ( 0.16 to 0.34 ) , triglycerides by 0.15 mmol/l ( 0.05 to 0.24 ) and diastolic blood pressure by 2.14 mmHg ( 0.94 to 3.33 ) . Significant improvements were also found in most psychological measures . Conclusion This study provides evidence that a type 2 diabetes prevention programme using lifestyle intervention is feasible in primary health care setting s , with reductions in risk factors approaching those observed in clinical trials .
