Trends in physical fitness among adults from Macao SAR between 2001 and 2020.
Article in BMC public health, 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
backgroundMonitoring temporal trends in physical fitness among adults offers insights into population health and informs preventive health strategies. This study examined such trends among adults aged 20–69 years from the Macao Special Administrative Region (SAR) between 2001 and 2020.
methodsRepeated cross-sectional population-representative data were collected in 2001, 2005, 2010, 2015, and 2020 (n = 20,653). Objectively measured data on body size and physical fitness were analysed. Trends in means were assessed using generalised linear models, with different adjustment and stratification strategies for sex, age, height, and weight. The ratio of the coefficients of variation and visual analysis of percentile curves were used to evaluate trends in distributional characteristics.
resultsDeclines were observed in lower body muscular power (ES = ‐0.34), lower back strength (ES = ‐0.55), flexibility, (ES = ‐0.16), balance (ES = ‐0.21), and reaction time (ES = ‐0.32) among young adults aged 20–39 years. Middle-aged adults aged 40–59 years showed declines in cardiorespiratory fitness (ES = ‐0.28), balance (ES = ‐0.18), and reaction time (ES = ‐0.46). Small improvements were observed in cardiorespiratory fitness (ES = 0.20) for young adults aged 20–39 years and reaction time (ES = 0.25) for older adults aged 60–69 years. Sex-specific temporal trends were observed in cardiorespiratory fitness, flexibility, balance, and reaction time across age groups. Distributional analyses revealed a widening gap across the population in fitness levels, particularly among lower-performing and younger adults.
conclusionsThese findings indicate a general decline in physical fitness among young and middle-aged adults, particularly males, in Macao SAR from 2001 to 2020. This highlights the need for age- and equity-focused interventions. Maintaining and improving adult fitness is essential for long-term health, functional independence, and active ageing.
