Bidirectional relationship between somatic pain and depression in Chinese adolescents: a cross-lagged study.
Article in BMC public health, 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
backgroundSomatic pain and depression are prevalent health concerns among Chinese adolescents. This study aims to examine the longitudinal reciprocal effects between these conditions in this population, explore the moderating role of gender, and propose recommendations to improve adolescent health. MATERIALS AND
methodsUtilizing a cross-lagged design, this longitudinal study tracked a convenience sample of seventh- and eighth-grade students (aged 12-16) from two middle schools in Sichuan between April 2023 and April 2024. Measures included the Patient Health Questionnaire (PHQ-9) to assess depression and a five-item somatic pain scale. Analytical methods comprised descriptive statistics, Harman's single-factor test, correlation analyses, t-tests, and structural equation modeling.
resultsCross-lagged analyses reveal a dynamic interplay between somatic pain and depression over time among Chinese adolescents, with gender serving as a significant moderator in this reciprocal relationship. Specifically, among adolescent boys, depression predicts somatic pain over a one-year interval, and somatic pain similarly predicts depression. In contrast, among adolescent girls, depression unidirectionally predicts somatic pain over the same period, with no significant effect observed in the reverse direction. Additionally, the association between somatic pain and depression is significantly stronger in adolescent girls than in boys at both time points. Furthermore, adolescent girls report higher levels of both somatic pain and depression compared to boys at both time points.
conclusionSomatic pain and depression exhibit a dynamic interplay over time among Chinese adolescents, with gender significantly moderating their reciprocal relationship. These findings highlight the need for gender-specific intervention strategies and underscore the importance of addressing both somatic pain and depressive symptoms with equal priority in adolescent health management programs.
