Description of intervention(s) / exposure
This is an observational study. All patients undergoing video capsule endoscopy that are recruited will have clinical parameters recorded (sex, age, height, weight, waist circumference, blood pressure and body mass index). A fasting blood sample will be collected for insulin, glucose and full lipid profile (total cholesterol, triglycerides, high density lipoprotein (HDL), low density lipoprotein (LDL)). Insulin resistance is to be calculated using the validated HOMA-IR (homeostasis model of assessment of insulin resistance) method. Participants are asked about the relevant past medical history (medically diagnosed diabetes, dyslipidaemia, hypertension, ischaemic heart disease, cerebrovascular disease or peripheral vascular disease) and medications.

The capsule endoscope system takes about 10 minutes to be connected and swallowed. The recorder is worn for 10-12 hours. Data and blood test samples are collected before the capsule endoscopy procedure and this takes about 15 minutes.

Statistical methods / analysis
Consecutive patients undergoing capsule endoscopy during the study period were recruited. The association between study variables and the outcomes were compared using a one-way analysis of the variance with t-testing. P values of less than or equal to 0.05 were considered significant. A multivariate multiple linear regression model was used to calculate the adjusted means of the clinical outcomes. All determinants with p-values of less than or equal to 0.25 were entered together in the full model of linear regression, and the model was reduced by excluding variables with p-values of greater than or equal to 0.05. Statistical analyses were performed using SAS version 9.00 (SAS Institute Inc., Cary, NC, USA).
