Examining lifestyle factors as potential moderators of the link between childhood adversity and comorbid psychological distress and obesity in early adulthood.

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
backgroundWhilst childhood adversities have been shown to be risk factors for mental, physical, and comorbid health problems in childhood and middle-to-late adulthood, there is less evidence for these associations in early adulthood. It is also unclear if lifestyle factors can modify the risk of these health outcomes following childhood adversities. This study aims to examine childhood adversities as risk factors for psychological distress, obesity, and their comorbidity, and further quantify the moderating impact of lifestyle factors. This could provide insight into potential protective influences against the detrimental health consequences of childhood adversities, particularly mental-physical comorbidity.
methodsAnalyses were conducted on data from the 1970 British Cohort Study (n = 16,407). The cumulative impact of parent- and self-reported adversities (range: 0-33) were consolidated across childhood (0-16 years) and examined as a predictor of psychological distress (Malaise Inventory ≥ 8), obesity (BMI ≥ 30 kg/m
resultsA one-item increase on the childhood adversities scale elevated the risk of psychological distress (OR [95% CI]; 1.11 [1.09, 1.13]), obesity (OR [95% CI]; 1.05 [1.03, 1.06]) and mental-physical comorbidity (OR [95% CI]; 1.16 [1.12, 1.20]). Compared to comorbidity, childhood adversity was a weaker risk factor for psychological distress (OR [95% CI]; 0.96 [0.92, 0.99]) or obesity alone (OR [95% CI]; 0.90 [0.87, 0.94]). No lifestyle factors were significant moderators of the association between childhood adversities and these health outcomes.
conclusionsConsistent with evidence from middle- to late-adulthood, childhood adversities showed a stronger association with comorbidity in early adulthood than mental or physical health problems alone. There was no evidence that lifestyle factors influenced the association between childhood adversities and comorbidity or individual health problems. Our findings highlight the importance of considering comorbidities when investigating the negative health consequences of childhood adversities, and therefore, the continuing need to identify factors which mitigate the increased risk of comorbidity.
