Timing of the decline in physical activity in childhood and adolescence: Gateshead Millennium Cohort Study
Open accessAbstract
Background and aim: There is a widely held and influential view that physical activity begins to decline at adolescence. This study aimed to identify the timing of changes in physical activity during childhood and adolescence. Methods: Longitudinal cohort study (Gateshead Millennium Study) with 8 years of follow-up, from North-East England. Cohort members comprise a socioeconomically representative sample studied at ages 7, 9, 12 and 15 years; 545 individuals provided physical activity data at two or more time points. Habitual total volume of physical activity and moderate-to-vigorous intensity physical activity (MVPA) were quantified objectively using the Actigraph accelerometer over 5–7 days at the four time points. Linear mixed models identified the timing of changes in physical activity across the 8-year period, and trajectory analysis was used to identify subgroups with distinct patterns of age-related changes. Results: Four trajectories of change in total volume of physical activity were identified representing 100% of all participants: all trajectories declined from age 7 years. There was no evidence that physical activity decline began at adolescence, or that adolescent declines in physical activity were substantially greater than the declines during childhood, or greater in girls than boys. One group (19% of boys) had relatively high MVPA which remained stable between ages 7 and15 years. Conclusions: Future policy and research efforts to promote physical activity should begin well before adolescence, and should include both boys and girls.

Written from the paper’s full text.
TL;DR
In the Gateshead Millennium Study, objectively measured physical activity was already declining by age 7 years in both boys and girls, with no evidence that the decline began or accelerated specifically at adolescence. The findings challenge the orthodox focus on adolescent girls as the main high-risk group for low physical activity.
Key findings
- Total physical activity declined from age 7 years in all identified trajectories: boys had three distinct trajectories and girls had one, together representing 100% of participants; no trajectory showed high childhood levels followed by a sharp adolescent decline.
- Mean total physical activity fell from 780 cpm at age 7 to 482 cpm at age 15 in boys, and from 746 cpm to 400 cpm in girls; MVPA fell from 75.5 to 51.4 min/day in boys and from 63.4 to 41.0 min/day in girls.
- MVPA trajectories were more complex: in boys, 3% had low and relatively stable/slowly declining MVPA, 17% had initially high but rapidly declining MVPA, 61% declined gradually, and 19% had relatively high and stable or increasing MVPA; in girls, 19% had low and relatively stable/modest declines, 62% declined gradually, and 19% had high initial MVPA with steeper declines.
- There was no evidence that physical activity decline began at adolescence, was substantially greater during adolescence than childhood, or was greater in girls than boys.
Methods
- Longitudinal cohort study (Gateshead Millennium Study) in North-East England, with follow-up at ages 7, 9, 12 and 15 years; 545 individuals provided physical activity data at two or more time points, and 217 at all four time points.
- Habitual total physical activity and MVPA were measured objectively with Actigraph GT1M accelerometers over 5–7 days at each time point; MVPA used a cut-point of 574 counts per 15 s, with a +9% correction applied to raw data, and age-15 data adjusted for season.
- Linear mixed models in SPSS described age-related changes; group-based trajectory modelling in STATA (Traj module) identified distinct trajectories, modelled separately for boys and girls using BIC and posterior probabilities.
Limitations
- The paper states that generalisability may be limited to populations with substantially different physical, social and/or policy environments; it also states that why changes occur was beyond scope, direct biological measures such as pubertal maturation were unavailable, the 3% boys subgroup needs confirmation in other populations, and measurement timing was largely determined by funding availability.
- Evident from the text: sample size declined across time points (431 at age 7 to 278 at age 15), and accelerometry excluded water-based activities, so some activity may be unmeasured.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-08, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-08 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
