Multidimensional factors associated with childhood obesity severity in southern China: a cross-sectional study.
Article in Frontiers in nutrition, 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
Background: Childhood obesity poses a major public health challenge, yet evidence on its graded associations with modifiable factors across dietary, behavioral, familial, and socioeconomic dimensions remains limited, particularly in Southeast China. This study aimed to comprehensively examine the multidimensional factors associated with childhood obesity. Methods: This cross-sectional study included 680 school-aged children from Fujian Province, China. Data on perinatal factors, family weight status, parental education, dietary intake, physical activity, and sleep behaviors were collected. Obesity severity was classified into four ordinal groups based on Chinese national standards. Ordinal logistic regression models were used to estimate associations. Group differences for categorical variables were assessed using the chi-square test. Results: Birth weight and infant feeding mode showed no significant association with obesity severity. Maternal care was associated with lower obesity risk in girls. Significant familial clustering was observed for paternal obesity (OR = 1.93, 95% CI: 1.20-3.06) and sibling obesity (OR = 2.26, 95% CI: 1.16-4.29). Lower parental education correlated with greater obesity severity. Breakfast frequency declined progressively with increasing obesity severity. At lunch and dinner, intakes of poultry, seafood, vegetables, fruits, and legumes decreased significantly across groups. Poultry intake at lunch was significantly associated with lower obesity risk (OR = 0.558, 95% CI: 0.354-0.878). Barbecue, cold drinks, and puffed foods were associated with increased obesity risk (OR = 1.763, 95% CI: 1.096-2.836). In contrast, nuts (OR = 0.477, 95% CI: 0.282-0.807) and biscuits (OR = 0.483, 95% CI: 0.322-0.723) showed significant were associated with lower risk. Regarding physical activity, ball sports (OR = 0.457, 95% CI: 0.227-0.918) and walking (OR = 0.368, 95% CI: 0.180-0.751) were significantly associated with lower obesity risk. Later bedtime and shorter sleep duration exhibited associations with obesity severity. Conclusions: Childhood obesity severity is associated with multiple factors, including familial weight status, parental education, meal diversity, snacking patterns, physical activity, and sleep behaviors. These findings may inform multifaceted, family centered approaches that could be considered for the prevention of childhood obesity.
