BV, baseline value of corresponding outcome variable; SD-PA, step-defined physical activity; NS, not significant at the 0.05 level; DX = diagnosis for relevant condition (high cholesterol, high blood glucose).
a Change = baseline subtracted from six-month follow-up.
b Full included all steps/day values; truncated included all values with those < 500 recorded as 500 steps/day and those > 30,000 recorded as 30,000 steps/day; excluded included only values between 500 and 30,000 steps/day.
c Continuous variable coefficient per 1,000 steps.
d Included age (years), sex, marital status (married or not married), education (less than high school, high school/GED, some college/technical), income (continuous as 12 categories), current smoker, BMI, DX, fitness (baseline value for 6-minute walk test), compliance (proportion of daily step logs completed), and baseline outcome value.
e For all significant outcome models: age, sex (decrease larger for males), fitness, and baseline outcome values had negative associations; income and baseline BMI values had positive associations.
f Change between intervention weeks 1 and 2 and remaining intervention weeks (3–27). Positive change indicates an increase during intervention
g Percentage of values which met at least 7,500 or 10,000 steps/day.
