Associations of accelerometer-measured physical activity, sedentary behaviour and different types of smartphone apps usage among university students: a 7-day tracking study.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundPrevious studies suggest that total screen time does not comprehensively predict health behavior. The effects on health behaviors vary by app type. This study examines the association of different app categories (social, entertainment, game, education) related to physical activity (PA) and sedentary behavior (SB) patterns among university students.
methodsThis study followed 345 university students aged 18–22 for 7 days. Physical activity (PA), and sedentary behavior (SB) were objectively measured using the ActiGraph GT3X-BT accelerometer. Smartphone app usage was tracked via objective daily survey logs. After the 7-day tracking period, semi-structured interviews were conducted to gather detailed information on app usage and physical activity. Data analysis was performed using SPSS 26.0 and R software.
resultsIn 248 participants (139 males, 109 females), Males had higher daily energy expenditure and more sedentary time (ST) compared to females, who spent more time in light-intensity physical activity (LPA) but less in vigorous-intensity physical activity (VPA). Males showed a positive correlation between entertainment app usage and ST (r = 0.271, p = 0.017) and a negative correlation with sedentary interval (SI) (r = -0.266, p = 0.019). In females, social app usage correlated with increased LPA (r = 0.321, p < 0.001) and VPA was positively correlated with screen time (ScT) (r = 0.195, p = 0.042). App usage also influenced SB patterns, particularly in active individuals. After controlling for confounding factors, gaming app usage in males who inactive decreased LPA (0.341 min, p = 0.036). In females, social app usage increased LPA (0.112 min, p = 0.018) but decreased VPA (0.012 min, p = 0.011) in those who inactive. ScT was linked to an increase in ST and to a decrease in SI time in both genders.
conclusionsDifferent smartphone app categories show distinct associations with physical activity and sedentary behavior, with social apps linked to more light activity and entertainment/gaming apps to more sedentary patterns, especially in males.
