Independent and joint associations of dietary diversity and physical activity on mental health among older adults in China: a cross-sectional 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 9 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
backgroundThe joint association of dietary diversity (DD) and physical activity (PA) on anxiety, depressive symptoms, and their comorbidity have not been extensively explored. Hence, this study focused on examining this association.
methodsData in this cross-sectional study was derived from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Based on self-reported dietary diversity score (DDS) questions were used to assess DD, ranging from 0 to 8. DDS < 5 was defined as insufficient DD and DDS ≥ 5 was defined as sufficient DD. PA was based on a self-reported binary question. Anxiety was assessed using the Generalized Anxiety Disorder Scale-7 (GAD-7), and depressive symptoms were evaluated by the Center for Epidemiologic Studies Depression Scale-10 (CESD-10). The independent and joint associations of DD and PA on anxiety, depressive symptoms, and their comorbidity were examined by multivariable-adjusted binary logistic regression models.
resultsIn this cross-sectional study, sufficient DD was independently associated with a decreased risk of anxiety (adjusted OR = 0.57, 95% CI = 0.50-0.65), depressive symptoms (adjusted OR = 0.69, 95% CI = 0.63-0.77), and their comorbidity (adjusted OR = 0.58, 95% CI = 0.49-0.68). Similarly, exposure to current exercise was also a significant protective factor for mental health. Importantly, co-exposure to sufficient DD and current exercise may amplify the protective effects on mental health (adjusted OR = 0.47, 95% CI = 0.38-0.57 for anxiety; adjusted OR = 0.36, 95% CI = 0.31-0.42 for depressive symptoms; adjusted OR = 0.37, 95% CI = 0.29-0.48 for their comorbidity). The robustness of these associations was demonstrated in four sensitivity analyses.
conclusionsOur study found that sufficient DD and current exercise were associated with a decreased risk of mental health disorders. Importantly, the combination of both appeared to enhance this protective effect. Our findings promote the joint assessment of DD and PA to provide new insights into health-related behaviors for prevention strategies for mental health disorders in older adults.
