An Exploratory Analysis of Adherence Patterns and Program Completion of a Pedometer-Based Physical Activity Intervention.

BACKGROUND

We examined participant characteristics related to pedometer program adherence and completion.

METHODS

Participants (n = 177, age = 43 ± 9 y, BMI = 29.5 ± 6.2 kg/m) were from sedentary workplaces. Baseline steps/day for women (n = 153) was 7230 ± 3447 versus men (n = 24) 8265 ± 2849 (P < 0.05). Records included pedometer use, days/week goals were achieved, and steps/day. Program completers (n = 104) fulfilled pre- and post-program assessments and at least 8 wk of recording. Non-completers (n = 53) met neither requirement, but pre-program data were available.

RESULTS

There were no significant differences in sex, age, education, or time at work between completion strata. The only significant baseline difference was an initial "worry about completing the program" (completer < non-completer; P < 0.05). The pedometer-based program was most successful in increasing physical activity in overweight or class I obese individuals. Participants with lower baseline steps/day were also more likely to complete the program.

CONCLUSION

The study findings have potential to inform effective health promotion planning.
