Cardiometabolic Syndrome
Conditions
Brief summary
Cardiovascular disease, type 2 diabetes mellitus and associated diseases combined are the leading health burden and cause of mortality worldwide; therefore, the necessity for an intervention is paramount. Dietary interventions to improve cardiometabolic health are highly sought after as they possess less risk than pharmacological drugs. It has been postulated that Berberine may be beneficial in improving cardiometabolic outcomes. However, to date, no research has explored this using a placebo randomized intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Blood triglycerides | Baseline | Capillary blood triglycerides - mmol/L |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Systolic blood pressure | Baseline | Systolic blood pressure - measured using a digital blood pressure monitor |
| Diastolic blood pressure | Baseline | Diastolic blood pressure - measured using a digital blood pressure monitor |
| Percent bodyfat | Baseline | Participants percentage composition of fat - measured using bio-electrical impedance |
| Waist to hip ratio | Baseline | Ratio of waist to hip circumference - measured using anthropocentric tape |
| Blood glucose | Baseline | Capillary blood glucose - mmol/L |
| Triglyceride glucose index | Baseline | Calculated as the natural logarithm of (blood triglycerides x blood glucose) /2) |
| Blood cholesterol - Total | Baseline | Capillary blood cholesterol - mmol/L |
| Blood cholesterol - LDL | Baseline | Capillary blood cholesterol - mmol/L |
| Blood cholesterol - HDL | Baseline | Capillary blood cholesterol - mmol/L |
| Coop-Wonka chart | Baseline | Psychological wellbeing - The Coop-Wonka chart is a six item questionnaire with a 1-5 scoring |
| Beck Depression Inventory | Baseline | Psychological wellbeing - the Beck Depression Inventory is a 21 questionnaire with questions that range in scoring from 0-3, thus the maximum score is 63 which is the highest depression score possible. |
| State Trait Anxiety Inventory | Baseline | Psychological wellbeing - the state trait anxiety inventory is a 40 item questionnaire with each question having a 1-4 score system, thus the maximum score is 80 which indicates the highest level of anxiety. |
| Insomnia Severity Index | Baseline | Sleep quality - The Insomnia Severity Index is a brief instrument designed to assess the severity of both nighttime and daytime components of insomnia. The Insomnia Severity Index is a 7-item self-report questionnaire yielding a total score ranging from 0 to 28. |
| Pittsburgh Sleep Quality Index | Baseline | Sleep quality - The Pittsburgh Sleep Quality index, is a questionnaire that consists of 19 self-rated questions, grouped into 7 components. Each component is scored separately, weighted equally on a 0 - 3 scale and the scores of the 7 components are then added to give a global score, which has a range of 0 - 21 with higher scores indicating worse sleep quality. |
| Epworth Sleepiness Scale | Baseline | Sleep quality - The Epworth Sleepiness Scale is a self-administered questionnaire with 8 questions. Respondents are asked to rate, on a 4-point scale (0-3) with a maximum score of 24. |
