| point-of-care HbA1c | Diagnostic Test | The Afinion2™ (Abbott, Oslo, Norway), will be used for the current study as it is recently validated. According to American Diabetes Association (ADA), pre-diabetes (pre-DM) is diagnosed if HbA1c is 5.7-6.4% and diabetes (DM) is diagnosed if HbA1c is ≥6.5% |
| Measure | Description | Time Frame |
|---|---|---|
| Point-of-care (POC) HbA1c | the measurement to diagnose pre-diabetes or diabetes; pre-DM is diagnosed if HbA1c is 5.7-6.4% and DM is diagnosed if HbA1c is ≥6.5%. | baseline |
| Measure | Description | Time Frame |
|---|---|---|
| Office blood pressure | a measurement to screen for hypertension; BP will be measured for 2 times (1-minute apart) and will be in accordance to the Hong Kong Primary Care Office guideline (e.g. the choice of cuffs and positioning). The average of the two BP readings will be used for analysis and management. Elevated BP is defined as a systolic BP (SBP) of ≥140mmHg and/or a diastolic BP (DBP) ≥90mmHg |

| baseline |
| Body mass index | a measurement for obesity. Body mass index (BMI) is calculated by weight divided by the square of height (BMI = weight (kg)/height(m)2). According the Hong Kong Centre for Health Protection, overweight and obesity are defined as a BMI of 23-24.9kg/m2 and ≥25kg/m2 respectively | baseline |
