Lifestyle factors, including physical activity status, associated with fragility fractures and falls: a cross-sectional study.
Article in BMC geriatrics, 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
backgroundFragility fractures, which frequently occur following falls, represent a growing concern in aging populations, severely affecting health-related quality of life (HRQOL) and increasing mortality. Although physical activity is generally beneficial for health, it may also increase the risk of falls and, consequently, fragility fractures. The present cross-sectional study was aimed at comprehensively analyzing factors, including physical activity status as a key variable of interest, associated with fragility fractures and falls.
methodsAn online survey was conducted among 4,967 community-dwelling older adults in Osaka, Japan. Data on a 5-year history of fragility fractures, falls within the past year, demographics, use of sleeping pills, polypharmacy (i.e., use of multiple medications), unintentional weight loss, and physical activity were collected. Physical activity levels were assessed using the International Physical Activity Questionnaire–Short Form (IPAQ-SF). Binary logistic regression analyses were conducted to identify factors associated with fragility fractures and falls. The EuroQol 5-Dimension 5-Level (EQ-5D-5 L) was used to compare HRQOL between participants with and without a history of fragility fractures and falls.
resultsFragility fractures within the past 5 years were reported by 7.3% of participants and were independently associated with female sex (odds ratio [OR] = 1.68, p < 0.001), polypharmacy (OR = 1.57, p = 0.001), fall history (OR = 2.63, p < 0.001), and unintentional weight loss (OR = 1.37, p = 0.031). Falls within the past year were experienced by 20.6% of participants and were independently associated with sleeping pill use (OR = 1.53, p < 0.001), polypharmacy (OR = 1.342, p < 0.001), and unintentional weight loss (OR = 1.86, p < 0.001). Moderate physical activity was not related to fragility fractures (OR = 1.03, p = 0.840) or falls (OR = 0.90, p = 0.144). In the HRQOL assessment, EQ-5D-5 L index scores were significantly lower among participants with a history of fragility fractures and falls than among those without such a history.
conclusionsThis study identified several key modifiable factors associated with fragility fractures and falls, demonstrating that physical activity was not independently associated with either outcome. Addressing these modifiable factors may help improve HRQOL in older populations.
