Temporal trends of physical fitness in northern Italian children (2014-2019): a repeated cross-sectional study.
Article in Journal of public health (Oxford, England), 2026. 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
backgroundPhysical fitness (PF) is a crucial indicator of long-term health in children, influencing risks for cardiovascular disease, obesity, and overall mortality. Despite its significance, Italy lacks a national surveillance system able to track PF trends in children, hindering efforts to combat rising obesity rates. This study aims to evaluate temporal trends in PF through a possible surveillance system in elementary school children.
methodsA repeated cross-sectional study was performed and consisted of assessing five PF domains: balance, upper and lower limb strength, cardiorespiratory fitness (CRF), and, speed-agility, along with BMI z-scores. PF trends were analyzed by age and sex, with logistic regression assessing the link between PF and obesity risk. Effects sizes (ES, Cohen's d) were computed to describe the trend's magnitude.
resultsCRF improved across all ages, especially in 10-11-year-olds (ES > 1.00). Younger children (6-9 years) showed gains in speed-agility, upper and lower limb strength, but these plateaued in older groups. We observed a decline in balance in 10-year-old boys.
conclusionsOverall, PF levels increased over time, with the most notable improvements observed in CRF. Implementing a nationwide PF surveillance system would facilitate continuous tracking of fitness trends, enabling policymakers to identify declines and develop targeted interventions.
