Phone messaging modestly improved measured activity in cancer studies, with uncertain persistence

A review found a small improvement in objectively measured activity after messaging interventions, but no statistically significant effects at follow-up.

The 30-second takeaway

Messaging interventions produced a small improvement in objectively measured physical activity after the interventions. Self-reported activity and step counts did not show statistically significant overall improvements. At follow-up, none of these activity outcomes showed a statistically significant effect. The results leave sustained benefit uncertain and apply to patients with cancer.

Keep in mind

This abstract-based summary cannot identify the control conditions, intervention lengths or follow-up intervals. Activity outcomes varied, and statistically nonsignificant results do not establish equivalence between groups.

THE NUMBERS, WITH CONTEXT

What researchers found

SMD 0.37 (95% CI: 0.10–0.64)

Objectively measured physical activity

Messaging versus trial controls after intervention; exact timing and control care were unreported. The standardized mean difference expresses the activity difference in standard-deviation units.

Different ways of measuring activity

The review pooled randomized trials and examined activity measured objectively, activity reported by participants and step counts as separate outcomes. The improvement in the objective activity measure did not extend consistently across these outcomes.

Subgroup findings need context

The review also reported step-count improvements in analyses involving more behavior change techniques and patients who had completed active cancer treatment. These subgroup findings do not establish that a particular messaging regimen is superior or that gains persist.
