Predictors of sedentary behaviour in adults: the role of social media addiction and physical activity - a cross-sectional study from Turkey.

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
Background: Sedentary behaviour is increasingly recognised as a major global public health concern due to its well-established associations with adverse health outcomes. Despite the rapid rise in digital media use, research examining the relationship between digital media use and sedentary behaviour in adult populations remains limited, especially in developing countries such as Turkey, where digital access and usage patterns are rapidly evolving. Therefore, to examine the associations between social media addiction and sedentary behaviour and to identify the predictors of sedentary behaviour in adults. Methods: This cross-sectional analytical study was conducted online with volunteer participants between April and June 2025. A total of 442 individuals aged 18-65 years living in Turkey participated. Data were collected using the sociodemographic form, the Bergen Social Media Addiction Scale, the Sedentary Behavior Scale, and the International Physical Activity Questionnaire-Short Form. Results: Social media addiction was weakly positively correlated with sedentary behaviour (r = 0.294, P < 0.001) and negatively correlated with physical activity (r = -0.124, P = 0.009), while no significant correlation was found between sedentary behaviour and physical activity (r = 0.020, P = 0.679). In a four-step hierarchical regression analysis, demographic variables explained 9.5% of the variance in sedentary behaviour. Physical activity was not a significant contributor (ΔR Conclusions: Hierarchical regression analyses showed that daily internet use was the strongest predictor of sedentary behaviour, while social media addiction had a small but significant effect. Physical activity was not a significant predictor, and several sociodemographic factors (age, gender, education, income, and employment) were also associated with sedentary behaviour. Overall, sedentary behaviour appears to be influenced by both demographic and behavioural factors, with digital addiction contributing modestly beyond traditional predictors.
