  - To examine associations of step accumulation patterns with all-cause mortality and CVD incidence in persons with 8000 or fewer daily steps.

  - 33 560 persons (mean age, 62.0 years [SD, 7.7]) who were engaging in 8000 or fewer daily steps and were free of CVD or cancer at baseline.

  - Over an average 7.9-year follow-up (266 283 person-years), 735 deaths and 3119 CVD events occurred.

  Cumulative all-cause mortality at 9.5 years decreased with bout length:

  - For bouts shorter than 5 minutes, it was 4.36% (95% CI, 3.52% to 5.19%);

  - for 5 to shorter than 10 minutes, 1.83% (CI, 1.29% to 2.36%);

  - for 10 to shorter than 15 minutes, 0.84% (CI, 0.13% to 1.53%);

  - and for 15 minutes or longer, 0.80% (CI, 0.00% to 1.89%).

  Cumulative CVD incidence at 9.5 years followed a similar pattern:

  - For bouts shorter than 5 minutes, it was 13.03% (CI, 11.92% to 14.14%);

  - for 5 to shorter than 10 minutes, 11.09% (CI, 9.88% to 12.29%);

  - for 10 to shorter than 15 minutes, 7.71% (CI, 5.67% to 9.70%);

  - and for 15 minutes or longer, 4.39% (CI, 1.89% to 6.83%).
