Associations of dietary patterns and screen time with depressive symptoms among adolescents in Shandong Province, China.
Article in BMC public health, 2025. 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
backgroundUnderstanding the interplay among dietary patterns, screen time, and depressive symptoms among adolescents is crucial for the development of effective prevention strategies. This study aimed to explore the associations between dietary patterns, screen time, and their combined effects on depressive symptoms among high school students in Shandong Province, China.
methodsUtilizing the Database of Youth Health (DYH) from the China Population Health Science Data Center in 2020, demographic characteristics, food intake frequencies, and screen time information were collected from 8,276 high school students aged 12-20 years in Shandong Province, China. Principal component analysis was employed to identify distinct dietary patterns, and logistic regression analysis was used to assess the associations of dietary patterns and screen time single and co-exposure with depressive symptoms.
resultsThe prevalence of depressive symptoms among adolescents in Shandong Province stood at 18.9%. Principal component analysis identified three main dietary patterns: balanced dietary patterns, high-protein dietary patterns, and processed dietary patterns. In comparison to students who maintained balanced dietary patterns, those who followed processed dietary patterns demonstrated a higher risk of depressive symptoms, exhibiting odds ratios (ORs) and 95% confidence intervals (CIs) of 1.62 (1.40-1.88). Additionally, adolescents whose screen time ≥ 2 h/d faced a greater risk of depressive symptoms than those whose screen time was < 2 h/d (OR = 1.46, 95% CI 1.25-1.70). Adolescents in high-protein dietary patterns with screen time ≥ 2 h/d, processed dietary patterns with screen time < 2 h/d, and processed dietary patterns with screen time ≥ 2 h/d all showed elevated risks of depressive symptoms. The respective ORs (95% CIs) for these groups were 1.71 (1.27-2.31), 1.60 (1.36-1.89), and 2.34 (1.86-2.94).
conclusionsOur findings demonstrate that co-exposure to high-protein dietary patterns and screen time ≥ 2 h/d is significantly associated with increased risk of depressive symptoms in adolescents. Notably, processed dietary patterns exhibit a more pronounced association, demonstrating heightened depressive symptom risks even when combined with either shorter (< 2 h/d) or longer (≥ 2 h/d) screen time durations.
