r, Pearson's correlation coefficient; SD-PA, step-defined physical activity; HDL, high density.

lipoprotein; LDL, low density lipoprotein; SBP, systolic blood pressure; DBP, diastolic blood pressure.

a Change = baseline subtracted from six-month follow-up.

b Percentage of values which met at least 7,500 or 10,000 steps/day.

c Change between intervention weeks 1 and 2 and remaining intervention weeks (3–27).

Positive change indicates an increase during intervention.
