* Raw data in pair sets. See text for multivariable regression results. 1Although anthropometry was collected on all 250 participants, data is only shown for 243, as evaluable serum samples for vitamin D3 analysis were available for this number (N) only. 6 samples were not obtained due to unsuccessful venepuncture and 1 sample was lost in transit to the laboratory. For the sub-groups some samples were not evaluable due to sample quality or loss. Sample number (N) is shown for each category. 2 Metabolic syndrome (N=234) is defined by the International Diabetes Federation as 1) Waist circumference: Europids and Undefined groups [such as Maori and Pacific Peoples] ≥ 94 cm (men), ≥ 80 cm (women), Asian (based on a Chinese, Malay and Indian Asian population) ≥ 90 cm (men) and ≥ 80 cm (women). Waist must be included, plus two or more of 2) Systolic and diastolic blood pressure ≥ 130/85 mmHg, 3) High density lipoprotein – cholesterol <1.03 mmol/L (<40 mg/dL) men, <1.29 mmol/L (<50 mg/dL) women 4) Triglyceride ≥ 1.69 mmol/L (150 mg/dL) 5) Fasting plasma glucose ≥ 5.6 mmol/L (≥ 100 mg/dL) and/or on treatment medication for the latter 4 conditions.
