Adherence
A 3-year worksite lifestyle intervention significantly improves cardiovascular health metrics in middle-aged adults, but the effect attenuates to non-significance after the first year when intervention intensity is reduced.
If you are implementing a lifestyle change for heart health, expect significant benefits in the first year if you engage actively with coaching and tracking tools. However, do not assume these benefits will persist automatically if you stop engaging with the program after the first year. To maintain gains, you must either continue with periodic check-ins or independently maintain the high level of behavioral effort established during the initial intensive phase.
At Year 1, the score improved significantly in intervention participants compared with controls [estimate 0.83 (95% CI 0.52–1.15) points]. However, intervention effectiveness decreased to non-significant levels at Year 3 [0.24 (95% CI –0.10 to 0.59) points].
Why this rating
Large randomized controlled trial (n=1020) with stratified analysis, though the primary outcome was not significant at the final timepoint.
