  • Data are means ± SD unless indicated otherwise. Values represent the first of two repeated measurements of triglycerides within a 5-year interval.

  • * A family history for type 2 diabetes indicates the presence of type 2 diabetes in a first-degree relative.

  • Eating breakfast denotes the percentage of persons reporting eating breakfast regularly. To convert the values for triglycerides to millimoles per liter, multiply by 0.0113. To convert the values for glucose to millimoles per liter, multiply by 0.0555. To convert the values for cholesterol to millimoles per liter, multiply by 0.0259.
