Efficacy of tailored-print interventions to promote physical activity: a systematic review of randomised trials.

In the other studies comparing tailored print to more rigorous interventions, a marginally significant positive effect was found (compared to the targeted materials) at mid-term but not at long-term [ 42 ] and significant increases in PA were found across conditions (tailored-print and tailored-internet and standard internet) but no significant between group diffrerence at mid or long-term were reported [ 22 ].
