Changes in accelerometer-measured physical activity and self-reported leisure time physical activity from adolescence to young adulthood: a longitudinal cohort study from the Fit Futures Study.

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
backgroundAdolescence is associated with declining physical activity (PA) levels, and potential prevailing changes into young adulthood are indicated, but less explored. This study investigates longitudinal changes in PA from adolescence to young adulthood among males and females in a North Norwegian cohort.
methodsIn the population-based Fit Futures Study, PA was assessed with both questionnaires (Saltin-Grimby Physical Activity Level Scale) and accelerometers (ActiGraph) at ages ~ 16 (n
resultsWe observed a significant non-linear U-shaped trend in accelerometer-measured moderate-to-vigorous PA (MVPA) over time (p < 0.001), with an initial decline in minutes per day from age 16 (mean ± SD: 70.7 ± 25.2) to age 18 (62.3 ± 23.8), followed by an increase to age 27 (67.5 ± 30.4). At age 16, males exhibited higher MVPA than females. By age 18 and 27, MVPA levels were similar between sexes. Accelerometer-measured sedentary time decreased linearly across all three surveys (p = 0.002). We observed distributional shifts in self-reported leisure time PA over time: vigorously- and highly active proportions declined, while the moderately active proportion increased, and the proportion of sedentary participants remained stable (~ 20%). Compared to vigorously active, the odds of reporting sedentary (OR: 1.07, 95% CI: 1.03 to 1.11), moderately active (OR: 1.11, 95% CI: 1.07 to 1.15), and highly active (OR: 1.07, 95% CI: 1.03 to 1.11) increased with each year from age 16 (all p ≤ 0.001). Compared to moderately active, the odds of reporting other categories decreased over time (ORs: 0.92 to 0.96, all p ≤ 0.001).
conclusionsWe observed non-linear changes in accelerometer-measured MVPA, indicating a U-shaped trend with a decline from 16 to 18 years, followed by an increase to age 27. Self-reported leisure time PA levels declined from adolescence to young adulthood, with decreasing proportions highly and vigorously active, while the proportion moderately active increased and the proportion of sedentary was unchanged. These results indicate that from adolescence to young adulthood, not all PA changes lead exclusively to increased sedentariness.
