Abstract

<abstract abstract-type="main" xml:lang="en" id="dme12173-abs-0001"> <title>Abstract</title> <sec id="dme12173-sec-0001" sec-type="section"> <title>Aims</title> <p>Rising rates of obesity have led to an increasing prevalence of Type 2 diabetes mellitus in young people. Uncertainty exists over the utility of screening younger adults for Type 2 diabetes, as existing data sets have focused on mature (> 40 years) cohorts. The aim of this study was to determine the prevalence of impaired glucose metabolism in higher risk younger adults.</p> </sec> <sec id="dme12173-sec-0002" sec-type="section"> <title>Methods</title> <p>Overweight (with an additional risk factor) or obese adults (18–40 years) were recruited for the Sedentary Time And Diabetes (STAND) randomized controlled trial.

Forty‐three per cent had a first‐degree family history of Type 2 diabetes. Previously undiagnosed Type 2 diabetes was present in 4.7% (<italic>n</italic> = 9). Of participants, 18.1% (<italic>n</italic> = 35) had impaired glucose metabolism: 4.7% (<italic>n</italic> = 9) HbA<sub>1c</sub> ≥ 48 mmol/mol (6.5%); 9.3% (<italic>n</italic> = 18) HbA<sub>1c</sub> 42–46 mmol/mol (6.0–6.4%); 3.1% (<italic>n</italic> = 6) Type 2 diabetes on oral glucose tolerance test; 6.2% (<italic>n</italic> = 12) isolated impaired glucose tolerance; 2.1% (<italic>n</italic> = 4) isolated impaired fasting glucose; 1% (<italic>n</italic> = 2) both impaired fasting glucose and impaired glucose tolerance. Of participants, 58.5% (<italic>n</italic> = 113) had dyslipidaemia, 28.0% (<italic>n</italic> = 54) had hypertension, 31.1% (<italic>n</italic> = 60) were vitamin D deficient and 7.3% (<italic>n</italic> = 14) had abnormal liver function.</p> </sec> <sec id="dme12173-sec-0004" sec-type="section"> <title>Conclusions</title> <p>This study identified a high prevalence of Type 2 diabetes and impaired glucose regulation in overweight and obese younger adults.
