Are technologies designed to support physical activity really helping young adults be active? A four-year longitudinal study.
Article in Journal of behavioral medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHealthy lifestyle technologies (HLT), including (i) exergaming systems; (ii) fitness trackers; (iii) fitness apps; (iv) interactive exercise equipment; (v) smart apparel; and (vi) heart rate monitors are highly commercialized, but it is unclear whether their volitional use promotes physical activity (PA). The first objective was to describe the average association between use of different types of HLT and PA levels. The second objective was to assess if changes in use of HLT predict changes in PA.
methodsWe used four yearly cycles of data from the MATCH longitudinal study, when participants were 20, 21, 22 and 23 years on average, respectively. Participants self-reported their use of HLT and their PA level at every cycle. General estimating equations were used to estimate (1) the odds of reporting any PA, (2) the association between use of HLT and PA level of participants reporting PA, and (3) the association between change in use of HLT and change in PA.
resultsAmong the 522 participants retained, approximately 40% reported using HLT. The most used HLT were fitness trackers (30%), followed by fitness apps (9%), interactive equipment (9%), heart rate monitors (7%), smart apparel (5%), and exergaming (4%). Whereas HLT use was not associated with the odds of reporting some PA (OR 1.2, 95% CI 0.9 -1.7), participants using at least one HLT reported 21% (95% CI 7-36%) higher levels of PA than non-users. Over the years, the adoption of HLT was not related to a change in PA, but discontinuing the use of HLT was associated with a 40% reduction in PA.
conclusionAlthough HLT users report higher PA than non-users, the use of HLT is not associated with a different likelihood of taking part in MVPA. The volitional use of HLT does not lead to an uptake in PA.
