Associations of moderate-to-vigorous physical activity and body roundness index with psychological symptoms in adolescents in mainland China: a national multicenter cross-sectional survey.
Article in BMC psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundDecreased physical activity and overnutrition among adolescents have become important public health problems shared by countries around the world. In addition, the prevalence of psychological symptoms among adolescents continues to increase, which negatively affects schooling and future quality of life. However, no studies have been found in the past on the association of moderate-to-vigorous physical activity(MVPA) and body roundness index(BRI) with psychological symptoms in Chinese adolescents. This study may provide theoretical support for the prevention and intervention of psychological symptoms among adolescents in mainland China.
methodsFrom September to November 2023, MVPA, BRI, and psychological symptoms were assessed in 43,031 adolescents aged 12-17 years from different regions of mainland China. The chi-square test, t-test, logistic regression analysis, and ordered logistic regression were used to analyze the associations that existed between MVPA and BRI with psychological symptoms.
resultsThe prevalence of psychological symptoms among adolescents in mainland China was 20.3%. The proportions of adolescents with MVPA of < 30 min/day, 30-60 min/day, and > 60 min/day were 46.0%, 40.0%, and 14.0%, respectively. The adolescent BRI value was (2.02 ± 0.95); boys (2.12 ± 1.03) had a higher BRI value than girls (1.92 ± 0.86), and the difference was statistically significant (t = 22.111, P < 0.001). After adjusting for relevant covariates, ordered logistic regression analysis showed that, overall, adolescents in the group with MVPA > 60 min/day and BRI quartiles Q1 as the reference group, adolescents in the group with MVPA of 30-60 min/day and BRI quartiles Q2 (OR = 0.65, 95% CI:0.51 ∼ 0.82) had a lower risk of developing psychological symptoms (P < 0.001); adolescents in the MVPA < 30 min/day group and BRI quartiles Q4 group (OR = 1.62, 95% CI: 1.30-2.02) had a higher risk of psychological symptoms (P < 0.001).
conclusionsThere is an association between MVPA and BRI and psychological symptoms among adolescents in mainland China. A decrease in MVPA and an increase in BRI were associated with an increase in the prevalence of psychological symptoms. In the future, we should effectively improve the MVPA level and maintain a reasonable BRI value in adolescents in mainland China to better promote adolescents' mental health development.
