Are all risks equal? Understanding the differential mechanism linking early environmental risk and obesity via the interplay of mental health and lifestyle factors.

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 mechanisms linking early environmental risk (EER) and obesity via the interplay of mental health and lifestyle factors in the early life stage remain unclear.
objectiveTo examine whether EER was associated with later mental health, lifestyle factors and obesity and to identify the mediating roles of mental health and lifestyle in these relationships.
methodUsing data from the Millennium Cohort Study (valid n=5401), we longitudinally assessed the relationship between EER (prenatal risks, neonatal risks, low socioeconomic status, maternal psychological problems and harsh parenting; 9 months to age 3 years), mental health problems in childhood (internalising and externalising problems; age 7 years), lifestyle factors in early adolescence (diet, exercise, smoking and drinking; age 11 years) and obesity in late adolescence (age 14-17 years). Structural equation modelling was used to test proposed pathways.
findingsThe proposed model showed an acceptable fit (Comparative Fit Index=0.926, Tucker-Lewis Index=0.875, root mean square error of approximation=0.034, standardised root mean square residual=0.046). EER was significantly associated with later mental health problems, lifestyle factors (ie, diet, exercise, smoking) and obesity. Higher EER was modestly associated with higher obesity risk via the interplay of externalising problems and drinking (β=0.01, p=0.036). The sex-stratified model results indicated differences between males and females.
conclusionBy highlighting the importance of EER and the mediating role of lifestyle factors in mental health and later obesity risk, our findings provide evidence of shared risk mechanisms linking mental and physical health. CLINICAL IMPLICATIONS: These findings suggest that integrating mental health assessment (especially externalising symptoms) with routine screening for adolescent alcohol use and other risk factors could inform more targeted obesity prevention in clinical and public health settings.
